battery drain after iOS 8.2

I have noticed that the battery of my iPad Air and New iPad are being drained within a day even on sleep mode.

I have been disabled the Updates in second plan it helped up a little but still have to charge ever 1,5 days.

Some one have the same problem?? What did to solve the problem?

It is really unpleased have to turn off severals setting just to get some battery life, that not why i bought an 128gb iPad air wi-fi+4g.
