Hey everyone,
So I just bought this z5 dual phone and installed the nougat 7.1.1 update (I don't know if this is the problem or not but everyone brings that up when they complain about the battery) , then I noticed that the battery drains SO FAST, it loses like 10 percent in 15 minutes while I'm using it. I have tried every thing previously suggested on the forum like system repair,turning off NFC and location, activated the safe mode and still had the same problem.
I really need to know whether I can solve this problem by myself or should I return the phone because it's faulty.
