battery started to drain quick directly after last update , normally it tooks my phone a day and half to go off and charge it again .. the phone is new i bought it on last october and i use it with caution no game even is installed on phone just few ...
i hope that too .. the point is that the phone is brand new, even I'm using a portable wifi to avoid using the mobile data ... since samsung announced that their devices battery won't be changed easily im using all the ways just for battery saving
