Well, I got it yesterday and I left it plugged in until this morning. However, I didn't realize that I didn't fully shut it down. So, that was dumb.
Anyway, now, I unplugged it this morning and it died within a matter of less than 4 hours, from a full charge.
I brought it down to 4%, then plugged it in and shut it off, fully. It was at 64% after about an hour and 15 minutes.
And, why the hell does it get so hot? What is that?
Auto-Brightness or do I want to just keep it on like 30%?
