I bought an iPad mini 2 it had a problem so I took it back to the store I bought it at and I got a new one, I feel that the battery on this one dies faster than the other one it might just be me but I want to figure out if the battery drainage is normal. The battery goes down about one percent every 6 or 7 minutes when watching Netflix or YouTube videos, when surfing the web it goes down 1 percent every 8 or 9 mins and when playing games it goes down about the same as watching videos is this normal? And on standby it drains a couple percent down within a few hours or when I leave it there overnight.
