I didn't find a related topic so i ask here.
I have a serious problem with my Intex Aqua Fish. Battery is draining too fast. I can lose almost 30% battery in one day with wifi,bt closed, no sim card, and no use at all, screen off. I ve heard also some times a reccuring camera focus sound without using the camera. Anyone experienced such problem? How can i check if phone doesn't go to deep sleep mode, or check the wakelocks?
