This article is part of series discussing Everything About How to Use the Samsung Galaxy S4.
EditHow to Charge your S4 Battery and Keep it Working Longer
There are many myths surrounding batteries, charging them, and keeping them charged.
If you are using your Samsung Galaxy S4 for the first time, you've probably been told that you're required to fully charge it, and then fully discharge it, with a strange list of other steps that you could easily mistake for some bizarre form of battery voodoo. Fortunately, you can ignore most of what you've been told, and even most of what you know from the older generation of NiCad batteries you're probably accustomed to.
- For reference, purposes, NiCad is short for Nickel Cadmium batteries, and they are what you've probably been using in any phone you've owned previously. They do require 'training', and need to be used a particular way to help prolong their effective life.
Your Galaxy S4 is different. It uses the latest battery technology, which is Lithium-Ion, or Li-ion. These batteries thrive in environments of burst use, where your device is never fully discharged, and is fully charged every day or so. In fact, it's best to charge them at around 25% or so battery life, which is what most people do already. However, unlike NiCad batteries, your GS4 battery should never be fully discharged unless it's incorrectly reporting the battery status. We'll discuss that in more detail later.
It is very important to fully charge your GS4 battery before using it for the first time.
Most people do this overnight, while they sleep, however, you can chose to do it in whatever manner is most convenient of for you. Just make sure to use the supplied charger if possible. This will charge your device more quickly than using a USB cable to charge it. Also, it's not necessary to unplug your phone the second it is fully charged. The S4 is a smart phone, in that it will stop charging once the battery is fully charged. Therefore, unless your device is defective, it's not possible to 'overcharge' it.
It is impossible to 'overcharge' a functional Samsung GS4, because the phone stops charging when full, and even if that fails, the battery also stops charging when it is full.
For reference, the factory standard battery status icons for the Samsung Galaxy S4 display either charging, or fully charged states. Charging is represented by a series of five circles, with a partially full battery (shown in the left image below). Fully charged is shown as a 100% full green battery (shown in the right image below).
EditHow to Charge your S4 Using the Factory Supplied Charger
This is the fastest way to charge your phone.
Using the supplied USB Power Adapter, the first time you fully charge can take from a few minutes to a a few hours, but usually takes two to three hours. Below you'll find the standard steps for charging your Samsung with the USB Power Adapter charger:
- 1Connect the USB cable to the USB Power Adapter.2Plug the USB cable mini jack into the mini USB jack of your Samsung Galaxy S4.3Plug your charger into the power supply socket.4Wait for your phone to be fully charged, indicated by a continuously lit green led.5Unplug the cable from your Samsung Galaxy S4.6Unplug your charger from the power supply socket.Alternatively you may leave it plugged in if it's in a convenient location, where you'll regularly be charging your phone.
EditHow to Charge the Galaxy S4 Using a Computer or Laptop
USB makes this possible.
One of the advantages the Galaxy's USB connection port provides is the ability to use any USB enabled device to charge your phone. However, due to the lower power output of a USB port, this method does take longer to charge your phone. Here are the steps to charge your phone using your computer or laptop.
- 1Plug the USB cable mini jack into the Mini USB jack of your Samsung Galaxy S4.2Plug the other end of the USB Cable into any USB port on your computer.3Wait for your phone to be 'fully charged.' (It will notify you.)4Unplug the USB cable from your Samsung Galaxy S4.5Unplug the USB cable from the computer's USB port.6That's it.You've successfully charged your GS4 using the USB port of your computer.
- Did you know that you can also use USB devices like your Playstation to charge your Galaxy S4? Just plug it into one of the spare controller slots, and it should charge - just like your controllers do.
EditHow to Charge your Galaxy S4 in a Car, Truck, or Boat
Your car needs to have a cigarette lighter outlet for this to work.
A holdover from a bygone era, the cigarette lighter outlet in cars and trucks has remained relatively unchanged for longer than almost any other electrical component in one. Anywhere in the world, cars still have these, but they've transformed from lighting cigarettes to powering and recharging electronics. So, if you're on the road a lot, or planning a road trip, you can easily recharge your Galaxy S4 with a car charger, which costs less than $10 from Samsung.
If you're in a boat, or on a motorcycle, you can purchase a special boat and motorcycle charger for your Galaxy S4, for about $5 or so. The installation is simple, and requires very little in the way of tools or expertise.
Whatever you choose, you'll want to follow these simple steps to charge your Galaxy S4 in a car:
- 1Plug the 'round' end of the charger into your cigarette receptacle.2Connect the retractable cord's mini jack into the mini jack of your Galaxy S4.3Once charged the battery icon on your Galaxy will have a full and continuous green light.4Unplug the retractable cord first from your Samsung Galaxy S4.5Then unplug it from your cigarette lighter receptacle.6Congratulations, now you know how to charge your S4 on the road.
- The charger you get is entirely up to you. You might prefer one with other features, such as the retractable car charger, like we've shown in the photo below.
EditHow to Keep Your S4 Battery Performing its Best
Li-ion batteries are pretty smart, as batteries go.
To give your Li-ion battery the longest life possible, there are a few simple steps you should follow.
- 1Fully charge your battery when you first start using your phone.If you just got a new battery, fully charge it just like you would if it was a new phone.2Make sure to recharge your battery before it goes below 15% charge.Recharging at 25% charge level is ideal.3Do not expose your battery to heat.This is especially true of leaving it in the sun, or in a car, as the inside of your car can get hot enough in the summer to damage the battery, or even cause it to explode.4Avoid fully discharging your battery to the 0% state.The only time you should ever discharge your battery to a 0% state is when it is not correctly reporting. An example of this is when your battery seems to randomly lose charge, or drop to zero. In such cases, let your phone fully discharge (0%), and then fully recharge it.
EditHow to Increase Battery Life on the Samsung Galaxy S4
If you want to get more time from each charge, try this.
If you're finding that your battery doesn't last as long as you thought it would, here are some tips to help you squeeze every last bit of life from it.
- 1Close all unnecessary applications when they are not in use.Use your task manager to view all active applications, and close the ones you aren't using.2Deactivate Bluetooth when not in use.3Deactivate WiFi when not in use.4Switch your device to 'Sleep Mode' when it is not in use.Auto-sleep may be turned on, but you can save even more power by pressing the Power Button once (which puts the phone in sleep mode) when you are not using your phone.5Deactivate 'Auto-Syncing of applications.'6Decrease the Backlight Time of your device.7Decrease the display brightness.8Turn off vibrate, and only use ring.9
EditHow to Tell How Long it Takes to Charge a Galaxy S4
Charge times vary depending on the method.
Normal charge times for the Samsung GS4 vary depending on whether you're using the wall charger, a USB charger, or a third party device. While there are some cool third party devices out there, some of them, like the Levin Solar Charger, can take a day or more to charge a device - but aren't intended as a substitute charger. Because of that, we'll just discuss the two most common forms of charging - USB and Wall Charger.
- 1Galaxy S4 Charging Time Using the Samsung Wall Charger:
2Galaxy S4 Charging Time Using a PC USB Port:
- Wall chargers are capable of delivering outputs ranging from 0.5A to 2.1A. The Galaxy S4 stock charger comes with 2A amperage. In theory, a totally dried out 2,600 mAH battery should be able to load up in less than 2 hours using a 2A charger.
- In practice, the Galaxy S4 uses Lithium-ion batteries, and because of the proprietary mechanisms that promote battery longevity, the charging time may be longer.
- A computer’s USB 2.0 port usually outputs 0.5A. This means that a Galaxy S4 phone will in most cases charge significantly slower than it would on a stock Samsung wall charger.
- A computer's USB 3.0 port usually outputs 0.9A. This represents an 80% increase in speed over a USB 2.0 port, meaning your phone will charge almost twice as fast.
3Samsung Galaxy S4 battery statistics and facts:
- It's important to keep in mind that different USB cables will also impact this process. Low priced USB cables are usually poorly shielded, and will 'leak' current, resulting in a much slower charging process.
4Bypassing the Galaxy S4 charge negotiation limitations:
- The battery is listed at 2,600 mAH (milliamps/hour)
- The charger and the handset undergo a process called 'negotiation' where the amount of power transmitted between the charger and the phone is defined. There is no universal standard for this negotiation process, so it is subject to proprietary preferences.
- The Galaxy S4 only takes the current it needs, and nothing more. This means that even if a charger is capable of delivering a maximum current of 2A, it will still depend on the result of the negotiation process at to how much actual current the phone will draw from the charger.
- Lithium ion battery powered phones usually employ a mechanism that slows down the charging rate as the battery approaches its full capacity. This is done for battery longevity purposes.
- One interesting device is the Practical Meter, which identifies the actual current being transmitted to your phone while charging. This lets you know approximately how long until your devices is fully charged.
- More importantly, it has the ability to override the 'negotiating' process between the USB port of the power source and the Galaxy S4, allowing the maximum charge speeds to be attained.
EditGS4 Battery Myths: True or False
Your Li-ion battery uses the latest technology - and requires special care.
The science of batteries has nothing to do with myth, yet due to the amount of time battery technology has been in use, there are certain things that people have come to believe about them that aren't necessarily true or accurate. This because, as technology changes, so do the best practices for prolonging the serviceable lifespan of that technology. Batteries are no different, and your Samsung Galaxy S4 uses the latest Li-ion technology, which is quite different that it's predecessor, the NiCad battery.
Read on to learn the difference between fact and fiction.
- 1You should wait until your battery is fully discharged, or at 0%, before recharging it.
FALSE: Your Li-ion battery uses a new technology, and fully discharging it can actually hurt the lifespan of your battery. Do not wait until it is fully discharged or at zero percent. You should actually charge your battery when it is at 25%, or at a low of 15%.2
FALSE: Your Samsung Galaxy S4 will automatically stop charging your battery when it reaches 100% charge. In the event this system were to fail, your Samsung brand battery is also equipped with an internal mechanism to stop charging when it reaches 100%. Combined, these two failsafe prevent any chance of overcharging.3 FALSE: See number two, above.4 TRUE: Overcharging your battery can cause it to explode, however, there are two failsafe mechanisms in place on the GS4 to prevent overcharging. Therefore, your phone will automatically stop charging when it is full, and your battery will not accept additional charge, even if your phone did not stop attempting to charge it. That said, should you bypass these safety features and intentionally overcharge your battery, it can explode.5 TRUE: It is always best to keep your battery charged whenever possible, so as to avoid fully depleting your charge.6 FALSE: Lithium Ion batteries have a set lifespan. Charge as needed, because charging your battery more or less will not change the lifespan of it.7 FALSE: This is true of NiCad batteries, however, it DOES NOT apply to Li-ion batteries.8 TRUE: You should avoid excessive heat with your Li-ion battery, as this can damage the battery.9 FALSE: Li-ion batteries are closed, and do not release gases when charging or discharging. You do not need to ventilate your phone.
EditTips and Suggestions on the GS4 Battery, and Charging it
- Use only original standard Samsung charger, batteries, cables and adapters. Using nonstandard accessories may cause damage to your phone, or void your warranty.
- When your phone display of battery charge drops below 15%, charge your phone as soon as possible.
- To speed up the charging process, close all running applications and wireless connections (WiFi, Bluetooth, SBeam) during charging.
- Make sure to connect your charger properly. An improperly connected charger will result in less receive charge, and can significantly increase resistance based heat, ultimately damaging your phone. Should damage from this happen, it will usually not be covered under warranty, as views this as damage due to negligence and misuse.
- While charging your phone, if the main power supply becomes unstable, your touchscreen may not function. Remove your charger from the main power supply, and wait until the main power supply is stable once again. You can also use an AVR (Automated Voltage Regulator) to stabilize your electric current.
- Situations where this may occur are any instance where you are using dirty power to charge, such as that from a generator, or in situations where your local or regional power supply is degraded. While not as common in America and Canada, it is a common problem in other parts of the world, and one users should be aware of.

Does charging a battery before it is depleted cause damage?
charging a battery before it is depleted cannot cause damage to your mobile phone
Actually, one of the things that causes the battery damaged is going all the way to zero battery depletion. It is suggested not allow it to get to zero, as it can degrade the battery’s life, especially if you have a lithium ion battery. Lithium ion is used for Samsung Galaxy S4 mobile phones. You should also be aware that there are different types of batteries used for various mobile phones:
- Lithium polymer batteries (Li-Poly)
- Nickel metal hybrid batteries (NiMH)
- Nickel cadmium batteries (NiCd)
- Lithium ion batteries (Li-Ion)
Lithium ion is the most popular, expensive, and current technology for mobile phone batteries. There are drawbacks, of course. Apart from degrading the battery’s life, it can also cause damage when it is overcharged for up to 24 hours. Additionally, it can explode if it is charged when completely drained. Why is this so? Lithium ion batteries have self-destruct circuits, which will disable the battery permanently, if they reach rock bottom.
So this is actually better than charging the battery when it is completely empty. Leave 40 percent of battery life and you can recharge it.
Yes, over a period of time it can cause damage to your device. It is recommended that you allow your battery to fully die or discharge before charging it back up fully.

Can Samsung S4 use a normal mini USB cable, or does the S4 require a special cable for charging?
Do I need a special cable to charge my phone?
No. Unlike Apple, Samsung does not natively limit its devices with proprietary hardware or software restrictions. Therefore, a standard mini USB cable will work for charging or data transfer purposes. The brand of manufacturer of the USB cable you choose to use does not matter. However, low quality cables are often poorly shielded, and will not perform at the same level as a higher quality component.
How long does it take my Galaxy S4 to charge?
What is the charge time from empty to full for my phone?
The normal charging time of Galaxy S4 is not definite, and varies according to a number of factors discussed previously in this guide. In theory, your device should completely charge in about two hours, however, some methods are noticeably slower than others, such as USB 2.0 versus the Samsung supplied wall charger.
The Practical Meter, discussed earlier in this guide, is a third party charging tool that can improve charging speeds of your Galaxy S4, or any other device you choose to use it with.
Do i need to charge my s4 before using for first time?
Is it ok to use my new phone if I did not charge it?
The battery that comes with your Samsung Galaxy S4 is already pre-charged, so you can use it out of the box, however, you should plug it into a charger while you are using it, so that you fully charge the battery. Manufacturer recommendations are that you fully charge it before first using it - however, most people generally set up their phone while it is charging, and many stores will set up your phone in the store, before it has been fully charged.
How often should I charge the battery of my Samsung Galaxy S4?
Can I charge my GS4 every day?
The Samsung Galaxy S4 makes use of a Lithium Ion or Li-on battery, and should be charged as needed. Ideally you should not let it drain below 15% charge, but doing so is not going to cause a major loss of .
Why is my Samsung Galaxy phone taking longer to charge than before?
For the first 3 months, it took two hours for my S4 to be fully charged. Now it takes three to four hours to fully charge. Is this normal?
No this is not normal. There are two possible causes.
- 1A Battery Draining Application:You may have installed a battery draining app or widget. When your phone is being charged, the app is still running in the background and consuming power. This can cause your battery to take longer to charge. Android and Samsung Apps don't go through the stringent power testing that iPhone Apps do, so it is possible that you could have an App draining your battery. This is especially true if your phone is draining the battery even when it is screen locked, and should technically be 'OFF', because some of these Apps can run constantly.2A Bad or Defective Battery:It is also possible that you have a bad battery. Note that with a battery, past performance is no indication of future performance. Your battery can go bad at any time, and either gradually, or all at once. Sometimes it is due to the natural progression of a battery through its lifespan, and other times it can be caused by dropping the phone, or a particular defect that wasn't apparent earlier in the lifespan of your battery. This is because batteries are made up of several small cells joined together. If one or more of those cells goes bad, the battery will still produce the same voltage, but the amps (output power) are reduced. This is why you experience diminished battery life. In this case, the charging time is particularly affected by one or more bad cells, as they often drain or hampers the charging of any remaining good cells.
- Note that you can usually get inexpensive Lithium Ion batteries on eBay from China. Some of our users have reported ordering replacements, and even upgrading batteries with a higher amperage than their original Samsung phone battery. Having a spare battery is a good idea anyway, but pay attention to any requirements of the Manufacturer's Warranty.
Should I charge daily as I did with my iPhone?
Hi, with my iPhone i charged it every day whether it was dead or not. Should i be doing the same with the Galaxy S4?
To make the most out of your Galaxy S4's battery, you are to charge it as soon as the battery goes below 50% of the total battery capacity. If you are a low to normal phone user, there will be days that you do not need to charge your device. For mid-heavy users, charging of phone is required at least a day. Charging two or more times a day is required for those people who heavily use their device for online gaming and movies.
No, it is recommended that you allow your battery to die or discharge fully at times in order to allow it to rest or not be fully over used.

How to stop charging when battery full for Samsung S4
When your battery indicator is showing a 100%, or if the battery is full green, then your phone has been fully-charged. In order to conserve energy, you need to stop your phone from charging. You can do this by removing the charging terminal of the charger from your phone's charging port. Your phone is set to automatically stop when battery is at 100%. However, it is always better to stop the phone from being charged because of the following:
- 1If the phone's ability to stop charging at full levels malfunctions, then it won't stop charging even at 100% and may cause overcharging.Though chances are slim that you will overcharged your battery, it is always best to stay on the safe-side.2An overcharged battery will have a shorter life.Again, there is a slim chance that you will overcharge your battery but if by chance you are part of the unlucky minority, and you have a faulty phone charging system, then you could risk overcharging. Cut-out that risk by making sure that you remove the power source once you have a full battery charge.3Problems on the power supply like brownouts and low voltage may damage the charger and the phone.Any unexpected, sudden or unstable power source could damage your phone's battery. Plugging out your phone after charging reduces your chances of being exposed to such unnecessary risk.
Charging speed slows down in S4
There are many possible reasons why speed of charging your Galaxy S4 slows down. It could be an issue with the phone, the charger, the power source or the battery itself. These are the following things that you need to check:
- 1Check your power source.You may have a source that has a low voltage output.
2Check your charger, it may be defective or not functioning at the optimum levels.Your charger could be the culprit. It may have some defective components that's causing you to charge slow. To know if this is the case, do these:
- You may be having a problem with the power supply in your area. If the power levels in your area is constantly fluctuating, then it can cause longer charging time. If this is your problem, consider buying a voltage regulator. Voltage regulators works by maintaining a constant voltage level so that you will be charging at a constant level. The regulator can also be used for other electrical items so this item is a must if you are on an area with erratic voltage levels.
- Your current power source may be the computer's USB port as against the previous charges where you directed it from the power outlet. As discussed in this article, you would have to deal with longer charging times if you are using a computer's USB port to charge your device since a USB port has a low voltage output as compared to power outlets. Normally, a USB give a charging current of about 500mA while normal power supplies give out 1A. This is the reason why it usually takes twice as long it is to charge using the computer's USB port than charging it directly to the power source using a charger.
3Check if your battery is still in good condition.Your battery may be defective and needs replacement. To check if this is the case, do these:
- When you are at 50%, reboot your phone. You can reboot your phone by pressing and holding the Power button and tapping on Restart. Reboot is important to make sure that you are running the same set of applications as we are doing a charging-comparison test.
- Once your phone restarts, normally charge your phone using your charger and take note of the length of time that it took to get it to 100% battery level.
- Use your phone normally and wait for it to reach 50% level again.
- Reboot your phone. Make sure that you do not manually start any applications yet.
- Borrow a similar charger from a friend or someone you knew. Confirm with the owner that the charger is functioning well. Charge your phone the same way and take note of the time to complete the charge.
- Compare the time. If the other charger charges by an hour faster, then there is a problem with your charger. If the difference is a 15 minutes and less, then your charger is still on good condition.
- If you have confirmed that the problem is with your charger, buy a new one. Do not attempt to fix it as you will be risking your phone for electrical damage.
4Background applications may be running that are eating up your battery juice.If this is the case, the following tips can help your charging time faster:
- When you are at 50%, reboot your phone.
- Once your phone restarts, normally charge your phone using your charger and take note of the length of time that it took to get it to 100% battery level.
- Use your phone normally and wait for it to reach 50% level again.
- Reboot your phone. Make sure that you do not manually start any applications yet.
- Borrow a similar battery from a friend or someone you knew. Confirm with the owner that the batter is in good health. Charge your phone the same way and take note of the time to complete the charge.
- Compare the time. If the other charger charges by an hour faster, then there is a problem with your battery. If the difference is a 15 minutes and less, then your battery is still be good condition.
- Once confirmed that it is a problem with the battery, buy a new battery. Do not attempt to do some work-around with your defective battery as you are risking your phone for bigger problems.
5Check if your phone is causing the slow charging.Your phone has a built-in charging components on it that is responsible for regulating the charging process. If these components are defective, you may experience slow charging or no charging at all. If you have confirmed that the problem is not with the power source, the battery, the charger, or some active applications, then there could be a problem with your phone's charging system. If this is the case, have your phone checked by a qualified Samsung technician. Make sure to check if you are still covered by the warranty to save on cost of repairs.
- Close all unused applications while you are charging. Take note that most applications do not terminate when you press the back button or the Home Menu, they merely minimize. To make sure that unused applications are closed, press and hold the Power button until you will be prompted with the task manager. Tap on the active application icon (a pie graph icon) located on the lower-right part of your screen. On the active applications tab, tap on the End button beside the application name to end the process.
- Turn off unnecessary connectivity features as these are great battery consumers and can relevantly delay charging time. If you are not using your Bluetooth, Wi-Fi, GPS and GPRS connection, you may want to turn them off for faster charging time.
I forgot to unplug my phone in my house it's already 48 hours right now,what will be happened
Samsung Galaxy S4 has a function to turn off the charging when the battery is at full levels. However, as time goes by, battery would slowly drain and would automatically by charged to full. What will happen here is that the phone will go into multiple and quick cycles of charging and this is not good for the battery. However, a single 48-hour incident may not do that much damage. Just make sure that you unplug it the soonest time possible. Chances of your phone exploding resulting to fire are fairly slim but since it is an electronic device, the possibilities cannot be completely ruled out. If you left your phone at home while plugged in, this is what you can do.
- 1Ask the help of someone who has access to your house.This is the first thing that you should do. Think of those trustworthy people who have the keys or know of a way to get into your house. Ask that someone to go into your house and unplug the phone from the charge. This is the most convenient and practical way to do. If this is not possible, then you may try of the other suggestions.2Get home fast.If you can get home by yourself, do it as soon as possible. If you have other appointments, check if it can be rescheduled and go home. If there is no way to reschedule and appointment, make sure to go home the moment you are done with it. Postpone any plans of dropping by the grocery to get your weekly needs, that can wait.3Ask help from authorities.Only do this option when the first two suggestions are not possible. Like you are out of the country or into something very important that you cannot leave any time soon. Call the police and ask their help for someone to get into your house and remove the charger plugged. You can also call the electric company and ask if it is possible to temporarily remove power from your house.
- Remember, you are liable to any damaged cause onto other people if, by chance, any accident or incident may happen due to your carelessness.
How long does it take to charge the battery of my Samsung Galaxy S4 for the first time?
Normally, a new phone with a new battery may charge from 3-4 hours using the supplied authentic charger. However, this can only be a rough estimate since there are a lot of factors to consider. For one, you may have used the phone from the moment you bought it to the time you start charging it. The way you used your phone before charging can affect the battery levels of the phone resulting to a longer initial charge. The longer you used your phone before charging, the lower its battery percentage. Opened applications and features used while charging will also affect the length it takes to completely charge your device. If you have turned your Bluetooth and network data on, enabled tethering on your device, or enable the Wi-Fi, then it will take a longer time for you to charge as these features consume battery power. Also, if you are charging through USB instead through the AC socket, then initial charging time will be slower and may take 6-8 hours.
How long is the charging time of Samsung Galaxy S4
As mentioned on the preceding question above, there are some factors that can affect the charging time of your Samsung Galaxy S4. Using the supplied charger, charging your Samsung Galaxy S4 from 50% to full would normally take about 2-3 hours. The following factors will affect the charging time of your Samsung Galaxy S4:
- 1Battery condition.Your battery health is a huge factor in determining the charging time of your Galaxy S4. A battery in good condition will have the normal charging time. A battery on bad health will have a lower charging time. However, do not let this fool you. Lower charging time for a defective battery means that it will also take it faster to lose battery juice. This is because a defective battery will only hold less juice than a healthy battery. Thus, it may appear that your phone is fully charged in a short time when the truth is, battery capacity had just been lessen.2Charger used.The type of charger used during charging will affect your Galaxy S4's charging time. This is because some chargers give a higher ampere output than other chargers. The higher is the Amp output of a charger, the faster it will take it to charge your phone.3Power source.The power source will also determine the charging time of Samsung Galaxy S4. A phone charging through a USB source will charge slower that one on an AC power source. This is because USB gives a lower charging output than the AC socket. Also, USB charging is also not constant. A USB 3.0 may charge faster than a USB 2.0 port as long as the right cable is used.4Device usage.Applications opened, radios used and screen usage will cause a longer time for your Samsung Galaxy S4. This is because any usage on your device will consume battery power. If you can avoid using your device while charging, then do it. This can help extend your battery life and lessen charging time for your battery.
How many Amps do I need to charge my Samsung Galaxy S4?
Samsung Galaxy S4 will charge at a charging input of as low as 0.5A to 3.0A. The higher the Amp rating of your charging, the faster it will take for your device to charge. If you can, consider getting a 3.0A output charger for faster charging time. Also, take note aside from the longer charging time, charging at 0.5A and 0.75A may still deplete your battery especially if you are using your device's radio functions. Having the screen on while charging at 1A may still deplete your phone's battery even if the device is plugged.
When should I charge my Samsung Galaxy S4?
You should charge your Galaxy S4 whenever its battery indicator shows a percentage a little less than 50%. This is the optimum minimum charging percentage of your battery as it allows your battery to have longer charging cycles. Avoid charging your battery at lower than 10% battery level, or worse, when the battery has been depleted already. Charging your battery at very low levels will shorten its useful life.
How to tell when Samsung Galaxy S4 is done charging?
You can tell when your Galaxy S4 has been fully charged when the battery icon indicator on the upper right part of your screen turns to a full green. If your battery icon has a percentage, a label of 100% on it means that your Samsung Galaxy S4 is done charging. Your device will also give a notice that it has been fully charged and will ask you to remove it from the charger. Also, even if the charger is still attached to your phone, charging will automatically stop at 100%. This is to prevent possible overcharging of the battery and overheat that may lead to damage in your device.
How to perform a fast charge on Samsung Galaxy S4

I couldn't charge my battery its keep showing 0% battery status?
My samsung galaxy mini2 battery not charging keep showing 0% and status with !(exclamation sign) i used new battery still is showing same please help me
Borrow a working charger and see if the battery still won't charge. Since your battery is new, the problem is now either on the phone or the charger. Use your charger to charge other phones to confirm if it is still working. If it won't charge with other devices too, then replace it. If it will charge, then the problem is possibly with your phone. Check on the suggestions on the question above if this is your case.
If you have used a new battery but getting the same result then you will need to first diagnose your USB chord to make sure the chord is in fact working properly. If the chord is working then it will be your charging port that is the problem on your device.

Do i have to wait for the light to turn green before i take it off,, been like 17 hours and not green yet?
Does light turn green, been 17 hours and still nothing ... when can i take it off
It should be showing you the green light on being fully charged. If the light hasn`t turned green after 17 hours, it is probably not working. Check by going into settings and then going into battery, you will know if your phone is charged or not. If it isn`t charged then there is something wrong with the phone and you need to get it repaired. If it is charged and the light is not on then, it is just the light that isn`t working and you can get that repaired as well. In either case, you will have to go to the repair shop, only that it is o.k. to not go if it is just the light.
Why is the red light flashing on my Samsung s4?
I have never switched chargers since i've had the phone but tonight the red light starts to flash instead of staying steady when my phone is plugged in to charge . Its doing it on and off . when its flashing it shows my phone not charging
When the LED light blinks red, it means that the phone is connected to a charger but there is an issue with the charging. Do the following to determine solution:
- use another charger- if it charges, the charger is broken
- tried another charger, still does not work- charge the battery only using a universal charger
- charged battery from universal charger (full), still does not power on- battery pin issue or bad battery, try changing the battery (if issue is the same, it could be a battery pin issue) For battery pin issue, send the phone to an accredited Samsung Service Center to get it fixed

Battery Disconnected message on SS G4?
OK - usually charge SS G4 overnight. Woke up this morning with the battery at 80%. I unplugged the charger, plugged it back in and now get 'battery disconnected' instead of 'charging'. Never happened before - and now the battery won't charge ..Cheers
This could be a couple things. Either the charging adapter is bad or the charging port on the phone has gone bad. The best way to test it is to use a new charging adapter to find out whether the old adapter is bad or if it`s the charging port that`s gone bad.

It's not charging and makes a noise every once in a while?
Not charging properly either with computer or a power storage device
It could be a battery or phone problem. To know for sure, you need to use another battery (of the same kind and brand for the same phone), if it works on your phone, does not emit any sound when charging, it can indicate that the battery is to blame.Buy a new one compatible for your phone. However, if it remains the same, it could be a problem with your phone. I suggest you have your phone checked and fixed in order to use it efficiently again.
First you will need to make sure that your USB chord is not the reason for the charging problem. Use your chord on another device to see if it will in fact charge the next device as well. If the chord is perfectly fine then the issue will be with your USB port on your device.

Why my battery icon is colored white instead of green? There are many possible reasons why the battery icon indicator of your phone is white instead of green. The most common reasons are these:
- You are using a customized theme. Some themes alter the battery icon's color. This is not a sign of any problem though. Depending on your them manager application, check if there is a way to change the battery icon color. If you can live with a white colored battery, then that should not be a problem; however, if you are not using any theme-altering applications, then you may need to check on the next possible reasons why you have a white battery.
- Your battery is close to empty. The battery is colored full green when it is fully-charged. At 75% capacity, your battery icon will be colored white from top to the upper 25% of it, and green on the remaining parts. At 50% capacity, your battery is white from top to middle part and will be colored green from the middle to the bottom. When it is close to being fully drained, you battery will be colored white. This means that your phone will power off anytime and you need to charge it to keep it running.
- Your battery is defective. When your battery is defective, it may only show an empty battery icon even if it still has power capacity on it. You can check it by inserting your battery to another working Galaxy S4 and see if the problem is being replicated. If the battery is colored green on the other device, then it could be a problem with your phone.
- Phone's battery capacity reader is defective. As mentioned above, if the battery is colored normally on the other phone, then your Galaxy S4's battery capacity reader may be defective. You can confirm this by using a working battery, with at least half remaining capacity. If the phone show's a white icon, then you may need to have your device checked. Check if your phone is under warranty. Defects of this nature are, normally, part of the warranty coverage.
