I just bought a new htc one m8, it's still in the box and I am super excited. My question regarding the first and also other charging is this: how long should I charge it now? Until it will show that's it's fully charged? Or wait some more? Shall I leave the phone off or can it be turned on? I know it may sound funny to some of you, I just want to make sure I won't destroy the battery. To get the most of it
Thank you for your answers and advices.
