How to Reduce LG G4 Battery Drain And Overheating issues

Change LG G4 Settings to extend Battery Life

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 LG G4 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 LG G4 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 LG G4 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.

Modifying the Sync Settings on your LG G4 to stop the Battery from Draining Fast

Another setting that you can tweak is the LG G4 Sync setting. This is used to deliver push notifications such as emails to your LG G4 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 LG G4. 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. In order to limit the location services on you LG G4, do the following:

Change GPS Settings to Improve your LG G4 Battery Life

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.

Check to see which Apps are draining your LG G4 Battery

Go into Settings > Device > Battery and you will see exactly what’s making your LG G4 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 LG G4. 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 LG G4 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. If you don’t have a rooted LG G4 then the first steps are for you:

How to calibrate LG G4 battery without root access?

Follow these Steps to calibrate your LG G4 Battery Performance:

  • Discharge your LG G4 fully until it turns itself off.
  • Turn it on again and let it turn off.
  • Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
  • Unplug your charger.
  • 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.
  • 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.
  • 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.
  • Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
  • 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 LG G4 won’t start. But again: do this only when really necessary, because it does have a negative impact on battery life.

Use an app to reduce battery drain on the LG G4

The first thing you can do to help save battery life on the LG G4 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 LG G4 device.

When you’re done with Greenify then check out the other optimization tips for maximum battery life.

LG G4 Screen seems to be too Hot

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. Read the reasons why your LG G4 maybe overheating and the things you can do to cool down your G4.


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.

  • To heavy of a load for too long of a time

    The LG G4 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 LG G4’s performance. Let’s have a look at a couple of the things that your LG G4 can do well but which might cause it to overheat in the long run.

  • To many things Running

    Things on your LG G4 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.

  • Heavy Streaming Videos

    Watching videos and other media content is one of the things that can make your LG G4 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 LG G4 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.

  • Heavy Gaming

    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 LG G4. Many of them require a data connection which means that your LG G4 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.

Note : 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.
