Hello! I have a serious problem with my phone. My battery drains very fast and changed the battery (the old one had swallowed), but with the new one it is still falling. From 60% in 2-3 minutes it drops to 0%. I do not know what to do next, hard reset-2 times and ... nothing. I tried charging with other chargers, but continued like this. I have almost no applications, I always clean everything up. Most spend when the phone is while idling. Dear people, help me ... I'm totally desperate now.
