I got yesterday a Galaxy Tab 3 and I want to be sure what's the best way for the first battery charge. On the shop, they told just turn it on, wait for the battery to finish and then charge it to 100% (3 times!).
When I got home I turned it on and the battery was at 50%. But then I saw on the little book in the box that said: when you buy a new tablet, or the battery has not been used for a long time, charge the battery.
So, what do I do now?
The tablet is in sleep mode with 20% battery.
Should I turn it off and charge it? Or just charge it as it is (on)?
