Fix: Sony Xperia E4 Battery Drain/Overheating

Does your Sony Xperia E4 battery drain very fast? Or does your Sony Xperia E4 overheat? This is a common problem among Sony Xperia E4 users, however, there are a few things that you can try to do to fix the issue. Sometimes the draining is a direct result of apps installed on your device. It could be that you have not optimized your battery settings and other settings on your device for optimal performance. Over the next few minutes you are going to learn what to do if your Sony Xperia E4 battery drains fast so read on for all the possible causes and solutions to your problem. We will begin with the battery draining issue and the possible causes and fixes, after which, we will talk about overheating issues and the possible causes and fixes for that problem in the second section.


The first thing you can do to help save battery life on the Sony Xperia E4 is install an app. I would suggest Greenify. This useful app allows you to place all your apps in a state of hibernation and they will only be activated when you choose to launch the app yourself. After you have finished using the app, the Greenify application checks for the amount of time that the app has been inactive and then places it back into hibernation. With no apps running in the background, you will definitely see an increase in battery health on your Sony Xperia E4 device. You can read this article to learn how to use the Greenify app to extend battery life on your Sony Xperia E4.


The first thing you need to do is turn off the automatic brightness feature and set the brightness to a lower setting manually (not so low that you can hardly see the screen). Turning your Sony Xperia E4 display brightness down is a simple way to seriously improve battery life.

The next thing you might want to do is limit location services. One of the most power consuming features of the Sony Xperia E4 is the GPS location services. And you might be surprised to know that it is used for more than just Google Maps. Social networking apps like Facebook, Twitter and even WhatsApp make use of the GPS functionality of your Sony Xperia E4 which in turn drains your battery even more.

And while location services are useful, limiting those settings boosts battery life and this is what we are focused on. In order to limit the location services on you Sony Xperia E4, do the following:


Go into Settings > Location > Mode and you will find three options: High Accuracy, which uses GPS, Wi-Fi and the mobile network to determine your position, which in turn uses quite a lot of power to do so; Battery Saving which, as the name suggests, reduces battery drain; and Device Only, which only uses the on-board GPS. You can also turn off location services altogether, but of course that then limits your devices capabilities.

You can adjust the settings to your liking. I personally use the battery saving option, unless I am out for a jog or walk, in which case I will momentarily use the High Accuracy setting.


Another setting that you can tweak is the Sync setting. This is used to deliver push notifications such as emails to your Sony Xperia E4 smartphone. When you disable syncing you also prevent a ton of app update notifications, which gives you time to actually connect your device to a charge port to install the updates.

Of course, you can choose to disable certain sync features while leaving the important ones (email delivery) enabled. Again, this is totally up to you. Lastly you can explore the battery settings on your Sony Xperia E4. This way you can get of feel of what is using up your battery life and take steps to reduce the load on the battery. Android devices have lots of settings that can reduce battery drain.


Go into Settings > Device > Battery and you will see exactly what’s making your Sony Xperia E4 battery drain very fast – and if you tap on each of the apps you can then adjust the settings to improve battery performance. Click on the dotted icon at the top right of the screen and you’ll see the option for Battery Saver. If you enable this you can specify when it should activate (never, 5% battery or 15% battery), and when it does it’ll seriously limit the over-usage of your battery. It’ll reduce app activity, disable syncing for some apps, reduce vibration, dim the screen, etc.

You can choose to customize these features to your liking for optimal battery performance on your Sony Xperia E4. However, none of them are mandatory and you will know what works best for you. To be honest the Greenify app already saves a ton load of battery life on my device and the extra settings that can be tweaked are only used when I really need to squeeze the extra life out of my battery.

Calibrate your Sony Xperia E4 battery

The Android operating system has a feature called Battery Stats, which keeps track of battery capacity, when it is full or empty. The problem is that it sometimes it become corrupted and starts displaying data that isn’t real, which, for example, causes the phone to turn off before reaching 0 percent. Calibrating your Android battery simply means getting the Android OS to correct this information so it is reflective of your actual battery levels once again.

It's important to understand that you can't actually calibrate the battery: it is, after all, just a cell that stores and discharges. However, lithium-ion batteries do include a printed circuit board (PCB) that serves as a protection switch to stop them from exploding or deep discharging.

How to calibrate Sony Xperia E4 battery without root access?

Method 1

  1. Discharge your SONY XPERIA E4 fully until it turns itself off.
  2. Turn it on again and let it turn off.
  3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
  4. Unplug your charger.
  5. Turn your phone on. The battery indicator will likely not say 100 percent, so plug it in (leave your phone on for this) and continue charging until it says 100 percent on-screen as well.
  6. Unplug your phone and restart it. If it doesn't say 100 percent plug the charger back in until it says 100 percent on screen.
  7. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
  8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
  9. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.

Please remember that it is not recommended to perform this process all the time. Even when your battery is so dead your phone won't even turn on, your battery still has enough reserve charge to avoid system damage.  Perform this process once every three months at the most. If it is required more often than that you have bigger problems at hand.

Put plainly: fully discharging a battery is bad for it. Trying to overload a battery is also bad for it. The good news is that charging batteries automatically shut off when their safe limit is reached and there's always a little in reserve even if your SONY XPERIA E4 won't start. But again: do this only when really necessary, because it does have a negative impact on battery life.

How to calibrate SONY XPERIA E4 battery with root access?

Even though it is not clear if clearing the batterystats.bin file has any meaningful effect on how the Android system reports remaining battery charge, there are those who swear by this method. So in the interests of fairness the process is included for you here (it is true that different manufacturers use the batterystats.bin file for different things). It's basically the same process as above but with the added step of a root-enabled app.

Method 2

  1. Discharge your SONY XPERIA E4 fully until it turns itself off.
  2. Turn it on and let it discharge and turn off again.
  3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
  4. Unplug your charger.
  5. Turn your phone on. The battery indicator will likely not say 100 percent, so plug it in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
  6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
  7. You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
  8. Now, install the Battery Calibration app and, before launching it, make sure your battery is at 100 percent again, then restart.
  9. Immediately launch the app and recalibrate your battery.
  10. Once you've calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
  11. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.

Now We’re going to go through the problem of the Sony Xperia E4 or the battery of your Sony Xperia E4 overheating. Please read on for more information on how to deal with this particular issue. Below you will find out how to find the cause of the overheating and what you can do to help resolve the issue.


If your Sony Xperia E4 or its battery is hot and you are looking for a way to check the temperature of your battery then you are in the right place. If you are unsure whether it’s your Sony Xperia E4 or the battery that’s heating up or getting hot, then there are ways to know for sure which of the components is causing the overheating. You can use these tips/tricks to help you find the root of the problem.


Here, you need to use the most insightful tidbit of information in order to diagnose the battery on your Sony Xperia E4 device. In order to get this information, you will need to access an in depth analysis of your device’s battery. There is a simple way to get this information however, this tool does not come installed on every Android device and it may also be absent depending on the version of Android on your device, and sometimes the carrier that you are subscribed to.

Nonetheless, there are still many devices that use the code to bring up information on your device’s battery, you can try this first before installing any of the recommended apps to find your Sony Xperia E4 in-depth battery information.  If it does not work, then please use one of the recommended apps outlined below to find gain access.

Start by opening the dial pad, as though you were going to dial a telephone number, and type in ##4636##. If this feature is available on your device, then a screen should automatically appear. You can choose and open the option that says Battery Information (there are quite a few other options as well).

You should then see the following information about your battery including:

  • Battery Status: should show whether the device is charging or if the battery is full.
  • Power Plug: shows how the device is charging, AC (wall charger), USB (computer) etc.
  • Battery Level: shows what percentage the battery is charged.
  • Battery Scale: should read “100”.
  • Battery Health: should say “Good”. If your Androids Battery Health shows “unknown” or “unknown error” then your phones battery might be having issues. If you see anything other than “Good” then I recommend that you power cycle (turn the phone off than on), enter the code again, open the Battery Information again and see if this option has changed. If it still doesn’t say good. Then there is a good chance the battery itself is defective.
  • Battery Voltage: really isn’t something the average phone user is going to need to worry about (unless perhaps it’s abnormally high) but from my experience I have found that the voltage for the battery of an Android cell phone is usually around 3.7V-4.2V.
  • Battery Temperature: this is the option that you want to check when your device seems to heat up or has started getting HOT as it should allow you to check the temperature of your cell phones battery. If the batteries temperature is above normal, then it would likely indicate the battery is heating up but if the battery temperature doesn’t seem to be too hot then the issue could be that the phone itself is heating up. Battery temperatures are going to vary of course but the battery in an Android cell phone often remains in the 30C range sometimes in the low 40s depending on the phones usage (86 °F – 104 °F) …
  • Battery Technology: usually just shows Li-ion (because of the common Lithium Ion batteries found in the majority of Android devices).
  • Time Since Boot: shows the amount of time since you last booted up or turned on the phone.

If the code does not work for your device, then here are the alternatives. These apps can provide you with the same insightful data as the ##4636## code so, after reading the description of each, download and install the one you’re most comfortable with.

Battery Drain Analyzer is a sophisticated app that tracks your battery and power usage behind-the-scenes to give you an idea of what’s using the most juice. Think of it as Android’s built-in battery usage app on steroids; it offers tons of statistics and numbers that should satisfy even the most demanding power user.

As the name implies, the app will analyze app and power usage and let you know which apps are draining the most power, or if it’s even an app that’s causing battery drain. The Analyzer screen shows what percentage of app drain is caused by what system activity, whether that’s your screen, applications, phone idling, Wi-Fi or Bluetooth radios, etc. Below that, it shows which applications are consuming the most battery, including the infamous Android OS battery drain, rated by percentages. If Facebook is using 65% of the battery drain caused by apps, for example, you’ve got a pretty good idea of what’s causing your power usage.

Battery Doctor is a helpful battery analyzer and extender that also has a few tricks in its toolbox that you won’t find in other apps. On the surface, it offers a very clean interface for checking out your battery life. It gives a rough estimate for how much battery life left you have left in your current charge based on your usage habits at the time, but it goes a step further by showing how much potential battery life you can save by turning off specific radios or application syncing. Turning off that Bluetooth radio that you aren’t using might squeeze an extra hour out of your current charge, for example. It can also estimate how much battery life you’ll get if you start doing things like playing games or streaming music. If you’re stuck at work for an extra few hours, this is a great tool for managing what you need to turn off to make your battery last for the rest of the day.

The really great part of Battery Doctor is the actual Doctor part of the application. It acts as a personal battery adviser by giving you tips on when to charge your battery for maximum battery life and what apps and hardware functions you can disable to extend your charge. Disabling haptic feedback, for example, gives a little more juice than you think it would.

There are many other apps on the Google Play Store but these are the ones recommended. You can check out some more of these apps here. Once you have the app then you can proceed to analyze your Sony Xperia E4 battery statistics to find the root cause of your battery overheating issue.


This one is a bit tricky. Sometimes it is best to check the battery of your device as a whole. What you’re checking for is to see if the Sony Xperia E4 battery is bloated or malformed in anyway. If the device is designed in such a way that you cannot remove the battery, then do not proceed as taking your phone apart will void your warranty. If you can gain access to the battery by removing the back cover then do so and perform a visual inspection of the battery.

If you cannot see any malformations, then set the battery down on a flat surface and see if it remains flat or if it rocks back and forth in anyway. Should the battery not sit flat then you may need to replace your battery.



If your device is still under the Manufacturer’s warranty which will also cover defective or malfunctioning parts, then you should take it in to have your device or battery replaced.  If there is no physical or water damage on your battery and it’s less than a year old, then you will likely get a replacement battery at no cost to you. Give your service provider a call and ask them about your cell phones warranty.

Note: most cell phones and cell phones batteries will have what is referred to as an LDI (Liquid Damage Indicator) somewhere on the device which, if exposed to moisture or liquid, will change from white to pink or red. If your battery’s LDI has been activated and contains any pink or red, then that battery is no longer covered under warranty and you will likely need to purchase a new battery instead.


If you’re going to purchase a new battery, then its best to go to a repair shop to have it replaced. This is your best chance at having a safe “procedure”.


A hot Sony Xperia E4 battery does not necessarily indicate a bad or defective battery. It may also indicate an issue with the Sony Xperia E4 itself and before you go off to replace the device or the battery, you ought to consider reading on below for some great suggestions on how to fix a Sony Xperia E4 battery that’s really hot or overheating.


The fact is that your Sony Xperia E4 will get warm. After all, they are electronic devices. This is why you should not panic if your Sony Xperia E4 is getting a bit warm. However, your Sony Xperia E4 should never get HOT! If your Sony Xperia E4 is getting hot so much so that it is actually over heating then you might risk damage to your device, yourself or those around you. What you need to do is figure out what is causing the problem and learn how to prevent your device from overheating.


The first thing that you can do is to find the location where the device is getting hot. It does not necessarily have to be the phone that I getting hot but it could be the battery or the charger and even the speakers that are causing the problem. So, where exactly does your Sony Xperia E4 have overheating problems?


When your device starts to get warm does it seem to be the whole phone or does it seem to be mostly on the back area where the battery sits? Perhaps it’s not device that’s overheating but the battery inside.


Is the device getting warm towards the bottom where you plug in the charger? Is your device only getting warm while being plugged into the charger? If so, then there might be an issue with the charger itself. Make sure to try a different charger, preferably one approved by the manufacture of your device, to see if your device continues to heat up.

If a new charger fixes the problem, then you can get rid of your previous charger and enjoy work with the new charger. If it’s not the charger, then continue the guide.


If the back of the device seems to be getting hot and it’s not exactly where the battery sits then there is a good chance that the Sony Xperia E4 itself is overheating. If this is the case, then there can be a few reasons why this is happening. Read on for a bit of info on this.


If the part of your device that you hold up to your ear or where you hear music/sound from is getting hot, it can indicate a high possibility that there is an issue with the device itself. Don’t worry we’re getting to the troubleshooting tips soon.


Your device’s screen can get warm of course but if the touch screen or display screen is getting too warm or even hot then this is another indicator that there is an issue with the device itself.

The tips outlined below will help resolve the issue with your device as it pertains to overheating and burning.


Now that you have narrowed down the overheating issue to the device and not necessarily an issue with the battery or the charger, it’s time to find out what you need to do to get the heating down. Below is a list of the most common reasons and best resolutions that you can use to combat overheating on your cell phone.


Things on your Sony Xperia E4 are the same as any other thing that you have around your household. Things can get cluttered and become overwhelming for your device. If your device has started to unexpectedly get warm or hot then there is a good chance that your cell phone has processes, such as applications, that are running in the background and you don’t even know that they are running. Some of which might even start running as soon as you power on your phone.

If you’ve read the article from the top, then you already know that you need to uninstall a few of these apps or put them in hibernation mode whenever they are not in use. As suggested, Greenify is a great app for getting this done.


The Sony Xperia E4 is a powerful device! That’s one thing we can be certain of. You can play games, watch YouTube videos, listen to music, capture pictures, watch movies, search the web, send messages and make phone calls.

While all this is good, there is a limit that you need to pay attention to. This limit affects how long and how often you can do the same things over and over before they take a toll on your Sony Xperia E4’s performance. Let’s have a look at a couple of the things that your Sony Xperia E4 can do well but which might cause it to overheat in the long run.


Watching videos and other media content is one of the things that can make your Sony Xperia E4 a great device. Watching a movie when traveling can make the time it takes to get to your final destination go by a lot faster. Watching movies and playing videos constantly however, can certainly require more work from the Sony Xperia E4 processor and not only can it consume a lot of battery power but it can cause things to get warmer over time as well, especially as our standards for media consumption moves to using streams that offer clearer picture with a higher definition.

Combine the load of playing a video with the load of a data connection when streaming content along with other processes running in the background (and over time your phone might start to get a little warm to the point of overheating.


The Android App store has a pretty wide selection of some pretty fun and entertaining games and more and more applications are being created and released every day. Some of these games and applications require more processing power than others depending on the complexity of the app and when you add this required processing power with lengthy usage then things can start to heat up a bit.

What you have to remember is that many of these games might very well require you to use other resources on your Sony Xperia E4. Many of them require a data connection which means that your Sony Xperia E4 now has to maintain an active internet connection via mobile data or Wi-Fi connectivity, the app might require to access your contacts both on your device and social media accounts, etc. All these things add up and your device can get extremely hot over time.


If the battery itself isn’t heating up, then the problem is less likely your battery that’s causing the problems but if your battery is old or malfunctioning (even if it passes the battery test mentioned above) then you might want to consider replacing the battery.

If your battery is defective or malfunctioning and you have had it (and your device) for less than a year, then you might be able to get a free replacement battery/device. If your device is a little older and no longer covered under warranty then you might be able to find a great deal on a new replacement battery/device online from stores like Amazon or eBay.



If your Sony Xperia E4 seems to start overheating when it’s in your pocket/bag/etc., then take it out of the confining area to let it have a bit of fresh air. If you need to keep your device nearby then you can keep it in a backpack (non-cluttered), locker, or in a protective case on your waist.


Protective cases are one of the best investments that you can make for a device. They help keep your device well protected and can certainly help save the phone from accidental falls or accidental damage. While it is recommended that you invest in a good case for your smartphone you may want to try using your phone outside of the case for a little while to see if the phone continues to overheat or if it helps prevents the phone from getting hot.


Other less common but possible reasons an Sony Xperia E4 can get hot.


Do you listen to music from your device while taking a shower? Do you keep your device in a sweaty pocket? Or has your device simply had an accident where you dropped it in some sort of liquid? Power issues and overheating are common problems that a water damaged Sony Xperia E4 can experience.

You might want to try and locate the LDI (Liquid Damage Indicator) sticker(s) on your device to just make sure that your cell phone is not experiencing any side effects of moisture or liquid damage. Your phone may very well have moisture damage and you might not even know it.


When was the last time your device got to rest for a few minutes? Does your Sony Xperia E4 remain turned on constantly throughout the day then remains on and plugged into a charger all night? It might just need to be powered off to rest for a little bit.

As Androids get used apps and processes can start to run and continue to run until they are manually stopped or the device reboots (which was mentioned above) but being constantly powered on can also cause minor software problems which can often be solved by simply restarting the phone.


This suggestion kind of goes hand in hand with too many things running at once but if you have an animated wall paper with 10 different widgets such as a clock widget, a weather widget, a favorite contacts widget, an alarm widget, a calendar widget, a music widget, etc. then these things are going to be running all at once, and they are going to be causing your Sony Xperia E4 to work harder, and could be causing your device to heat up. Chances are your Sony Xperia E4 has some widgets on its home screen(s) and you didn’t even know it.


If you don’t know what overclocking means, then you can likely disregard this little piece of advice all together but your device is just like a computer. If you have manipulated or customized the software on your Sony Xperia E4 to get it to go faster or run differently then you may have inadvertently caused the overheating on your device.

Just remember that if you choose to overclock your Android and as a result it’s getting hot, heat can lead to a shorter life span for your device and can even result in hardware damage depending on how hot your phone is getting.


Outdated software is not likely the culprit for your phone heating up but I thought that I would add this to the list as updated software can help a cell phone run smoother which can cause less strain on your phone and might help to lower its average temperature.


Much like the possibility of liquid or moisture damage if a part of the device itself has become damaged then that part may need to be repaired or replaced in order for your device to function properly again; in this case for your device to stop overheating.

Try to think back to when your mobile phone started to get hot. Can you remember anything happening to the device around that time that could shed light on the recent overheating issues? Was the device dropped accidently? Are there any signs of physical damage on the device? If so, then this might be the culprit and fixing it might be more of a challenge as the damaged piece that’s causing the device to heat up would have to be located and repaired or replaced.


Just like a possible hardware issue can you remember downloading any new applications or programs etc. around the time that your Sony Xperia E4 started to get hot? If so, then you may want to locate that application and disable it or even temporarily uninstall it just to rule out the possibility that it’s not that app that’s causing any problems on your device.

This should go hand in hand with checking your running applications, which was mentioned earlier. If you notice that a certain application is running every time that your phone starts to heat up and you have to force stop or force close that application to get your phone to cool off, then you might need to decide if it’s worth it to continue to use that application. You might want to rule out that application completely by temporarily uninstalling it. If you uninstall it and your device seems to stop getting hot, then you will have located the issue and you could try re-installing it to see if a fresh copy helps but if not you might need to decide to keep that app (or apps) off your phone.

If you have done everything that you can think of to try and get your Sony Xperia E4 to stop heating up and it’s still getting hot, then you might also want to consider backing up all of your device’s important information and then perform a hard reset on the unit. A hard reset or factory data reset removes all user data from the device and it back to like new condition. This can help rule out the possibility that something found its way onto your device and is causing problems as the reset would help remove that “something” (whatever it may be) from the device. The only catch is that it removes all of your other information as well.


Do NOT put your device into the fridge or worse a freezer. Exposing your cell phone to extreme temperatures coupled with moisture is just a bad idea all around and is definitely not recommended.


If you have tried ALL of the suggestions in this article, then chances are your device is experiencing a hardware malfunction or another issue that cannot be resolved through standard troubleshooting and at this point you will likely need to look into your possible repair or replacement options. Luckily if your Sony Xperia E4 is still less than a year old and doesn’t have any physical or liquid damage it is highly likely that your device is still going to be covered under the manufactures warranty. If so, then your cell phones manufacture may be responsible for the repair or replacement of your unit.

If you have confirmed that your Sony Xperia E4’s battery is at fault and is getting hot to the point of overheating, then you may need to consider a replacement battery. You don’t want a hot battery to cause damage to your cell phone and cause even more trouble later on.
