Why is my battery draining so fast?

[AC Question]

Hello,

Yestarday I have updated my HTC ONE M9 to version 1.40.401.8. After this update my HTC is draining battery like crazy, 1 min on Youtube is 1% (Volumen on 50%). Before update I could do more activities.

Thanks for anysort of help!

Maybe the the manufacturers need to release another update fixing this issue.
