I don't get it. So many people care about this stupid estimated time. Why???
It just calculates the estimated time based on the usage of the last 15 mins or so. So it doesn't make any sense yo either look at that number or even compare it to others!!!
Mine shows 18 hours. If I play a game it will soon show 4h or something like that.
Just remember when you took it off the charger and when you plug it in again. THAT'S THE ACCURATE NUMBER !
