Problem: Poor battery life and overheating – Common OnePlus 6 problems and how to fix them
- Look in Settings > Battery and see what might be causing your issue. If a specific app is draining a lot of battery life, then you might consider uninstalling it.
- Since the biggest battery drain is generally your screen, you can always save battery life by dialing down your screen brightness in Settings > Display and reducing the time it takes for your screen to go to sleep by going to Settings > Display > Sleep.
- Watch out for areas where you get a consistently weak signal and consider turning mobile data off when the signal is weak because this can really drain your battery quickly.
- OnePlus has been releasing a steady stream of software updates, so look in Settings > About Phone > Check for updates and make sure you have the latest.
- Sometimes a simple reboot can make a difference, especially if you haven’t done one recently. Hold down the power button and tap Reboot.
- It’s worth wiping the cache partition to make sure it’s not the cause of your battery issue. Hold down the power key and tap Power off. Once the OnePlus 6 is off, press and hold the power key and the volume down key simultaneously. It should boot into recovery mode, where you can navigate with the volume keys and select options with the power key. Select your language, then choose Wipe data & cache > Wipe cache > Yes > Reboot.
- As a last resort, you might consider factory resetting your OnePlus 6. Back up everything first and then go to Settings > Backup and reset > Factory data reset > Reset phone > Erase everything. Once your device reboots, try setting it up as new without restoring a backup, and test to see if the battery issue is gone.
