I just bought a brand new Zonda a450 with android 4.4, i was quite surprised when the battery started to drain too fast, even taking a photo with flash could take 3% of the battery instantly. I searched in google on how to optimeze the OS, remove useless apps and widgets, etc. but i just saw a slighty improvement.
From what i see the device being idle and the phone being inactive take 50% of the battery! What i can do to reduce the percent used battery? since these two aren't apps i couldn't find an answer in google. Anyone one else had this problem? how i can fix this issue?
