Thank you very much Teknologic!

As I usualy use my tablet at home, it is easy for me to charge it whenever it is better for the battery.
One last question: Can I charge it also at any level of battery, without taking risk for the health of the battery? For example: The battery lever is at 60% and for some reason I want it full for tomorrow. It is better to use it until 20% and charge it or there is
no problem to charge it at 60%?
Thanks a lot, really helpful people here
