I have noticed this with a cheap Window tablet i acquired recently. Left alone it will eventually hibernate, something my Android tablets have never attempted.

I have noticed this with a cheap Window tablet i acquired recently. Left alone it will eventually hibernate, something my Android tablets have never attempted. Similarly, when it goes below 4% battery it will basically force a hibernate. That said, all mobile devices, laptops included, have a "force shutdown" option activated by holding the power button for x seconds.
