After all those years last month my phone began to lose power very quickly - after a full charge, in about 18h the battery is total empty without touching the phone - wifi and data turned off.
Normally it was about 50% in almost 2 days - i use phone at most 5-10 minutes a day.
I have tested everything what i can think of:
- Re-flashed and re-pited few times - tested with different roms from 4.4.4 to 9.0, Clean install - no gapps, Stock roms 4.1.2, Without SDcard, Airplanе mode ON, No sim and no SDcard.
Then i bought a new battery same as the old i was using - Polarcell 1800mAh, and for 2 days I did proper charging for a new battery without cutting corners, and after that i did most of the above tests again - and gave me the same result.
Now here i am, after ~20 days of testing writing this post.
If anyone has an idea then can help it would be great, otherwise i'm thinking to buy a new S7 Edge.
