A couple of weeks ago, I started experiencing some reboot and boot loop issues with my LG G3.
I noticed that it would suddenly reboot while I was using the phone – browsing the Internet, using apps, or playing games. At first, I thought that it was the built-in safety measure to prevent the phone from being damaged due to overheating. Then I remembered that I turned OFF the High Temperature Property and the Thermal Daemon Mitigation settings from the Hidden Menu so that couldn’t be it.
After observing it for a couple more days and I noticed that the phone rebooted even though the phone was barely used and the phone’s temperature wasn’t that high. Then as the days passed, I also noticed that the reboots happened more frequently and now it became worse because it would get stuck on a boot loop. The only way to stop it the boot loops was to boot the device into Safe Mode*. The phone would get to the home screen and I’m able to access the app drawer but as soon as I reboot the phone into Normal Mode, it would go back to the annoying boot loop.
Some LG G3 owners have reported experiencing these reboot/boot loop issues after upgrading to Android 5.0 Lollipop and it’s confirmed to be a software issue. In my case, my device was still running on Android 4.4.2 KitKat so I know that it wasn’t the problem.
I tried to disable and/or uninstall some recently installed/updated apps to see if those were the culprit but the problem persisted. Then I noticed that whenever I plugged in my LG G3 to a power source, the phone worked fine. But as soon as I unplug it from the charger, the device would go into a boot loop after a few minutes.
With that, I determined that the culprit was the LG G3’s battery. I purchased the Anker 3000mAh Li-ion Battery for LG G3 from Amazon for $15 and as soon as I replaced the original battery with it, the boot loops stopped!
If you happen to experience frequent reboots or boot loop issues on your LG G3 or any Android device, make sure to check the battery first before you try to fix the software, reformat your device, or bring it to the shop for repairs.
Anyone here who had a similar experience to this with their LG G3 or Android device? Was it also caused by the battery or was it software-related? Please share your thoughts by leaving a comment below.
*reboot the phone and when the LG logo appears, long press on the Volume Down button and hold it until you see the home screen.
