Those who are suffering from battery issues after one ui update..no matter which device you are using. Just do 1 things 1. Dial *#0228# then click on quick start and select ok. This will re calibrate your battery stats and it will sure give u good back up after that.
Personally, I tried this one , now am getting huge backup.
But one thing keep in mind, whenever you will do ,do this after full charge and after that drain the battery till 0.
