Fix: Samsung Galaxy J7 MAX Battery Drain/Overheating

Does your Samsung Galaxy J7 MAX  battery drain very fast? Or does your Galaxy J7 MAX overheat? Overheating and battery drain are common problems among Galaxy J7 MAX  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 learn what to do if your Galaxy J7 MAX battery drains fast. So, read on for all the possible causes and solutions to your problem. We begin with the battery draining issue and the possible causes and fixes, after which, we talk about overheating issues and the possible causes and fixes for that problem in the second section.


Turn off the automatic brightness feature.  Set the brightness to a lower setting manually (not so low that you can hardly see the screen). Turning your Galaxy S3 display brightness down is an easy way to improve battery life. The next thing to do is limit location services. One of the most power consuming features of the Galaxy S3 is the GPS location services.

Your Galaxy J7 MAX uses Location Services for more than just Google Maps. Social networking apps like Facebook, Twitter, and even WhatsApp make use of the GPS functionality of your Galaxy J7 MAX, which in turn drains your battery even more.

And, while location services are useful, limiting those settings boosts battery life To restrict the location services on you Samsung Galaxy J7 MAX, 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 onboard 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 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.

Calibrate your Samsung GALAXY J7 MAX 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 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 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 GALAXY J7 MAX battery without root access?

  1. Discharge your GALAXY J7 MAX thoroughly 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.
