Hi,
I owned a Huawei Ascend Mate 7 Gold 9 months ago, and I was very happy because I could use the phone for more than 2 days withouth charging. But recently, the battery started to drain VERY FAST :(.
For instance, if I go to sleep with the phone at 100%, when I wake up (8h later) , the battery is at 70% or less. With my investigation, I tried/found that:
-The problem is not caused by deep sleep mode, or at least "CPU Spy" shows that the phone is able to do it.
-I tried wipe (factory reset/partition/cache) with no results.
-I calibrated the battery but the problem persists, also I tried charging with 1A charger.
-"GSam Battery Monitor - Root" shows that 47% of the battery goes to "Android System" and another 20% goes to "Kernel (Android OS)".
The issue started at the last week, and the first thing I did was updating Lolipop (I was using it for more than 4 months) to Marshmallow 6.0 (B561). I don't know what do to now, ATM I'm underclocking the CPU, but that's a temporally solution. I always take the battery with a lot of care, I don't know why is happening this.
If someone could help me, I will be very thankfull :D.
