If the voltage go down together /battery and voltage/ the problem is battery?
At the moment voltage is 4065/4056. The battery lost 4% and voltage is 4065/4056.

But i see in history tab.. The voltage is down. 98%  is 4073vM, 95% - 4100vM 96% - 4061vM

Don't know if this is the proper place to post... Please move as necessary.

I'm having an issue with my C Note for a while now... I have had this phone for about 3 months. The battery life was awesome for the first 3 weeks or so (no update)... Then after it kept prompting me to install updates I reluctantly did so and since then I've had a noticeable increase in battery drain, even when idle.
Uninstalling apps one by one; hard resetting; factory resetting; clearing data cache did not help any.
Previously where I could easily get 2 days usage on a single charge I now have to charge daily. Even today I powered on at 77% and with only 1hr 20mins screen time it has drained to 38% battery already.

Is there any way to fix this? Or even reinstall the stock OS without update? Thanks in advance.
