A:AnswerMost devices recommend that you initially charge the battery to 100% before using it. Then after that you can use the battery until it's drained.
It used to be the case with older batteries that they had a memory and if you didn't charge them fully all the time you ran into problems with the battery draining too quickly.
But all new devices come with improved batteries they don't have a memory so you can charge them at any point between 100% and 0.
I hope this clarifies the instructions.
A:AnswerThe tablet is not capable of displaying two "windows" or apps on screen at once. There may be an app available in the store that is capable of that though.
