Why Your Tablet Turns Off Itself & How to Fix it

To avoid this, it is a good practice to occasionally restart your tablet after heavy usage or using it for a couple of days to reset the memory, clear app caches, and reset the system.
2 – High CPU Usage
Although your tablet’s CPU may be capable of running so many apps at once in the background, the long-term usage of the tablet will require the CPU to reset, making your tablet to keep turning itself off automatically. If this happens to your tablet after you recently installed a new app, try to uninstall (or freeze) the newly installed app ASAP and restart your tablet to check if the problem persists.
3 – Scheduled Power On and Off

While you have no control over firmware bugs, there is something you can always do to prevent or fix firmware bugs from causing your tablet to turn itself off. That is updating your tablet regularly when new system updates are released.
Mind you, only update your device from the phone’s settings, device/system update. Installing the update elsewhere may brick your phone and void your warranty.
