Charging, and what actually wears a battery out

Charge it without worrying about it, and say what actually wears a battery out.

A tablet battery is not used up by being on. It is used up by the screen, and then by the loudspeakers, and then by very little else.

That is why the same tablet lasts two days on a bedside table and four hours in front of a movie. It is also why turning the brightness down is worth more than closing every app you have ever opened.

What to remember

Try this

Turn on the battery percentage on your own tablet, if it is not on already. Guessing from a small picture is what makes a battery feel unpredictable, and the number is the whole cure.
