Phone resetting might be improved battery life. Specially after a software upgradation

A. Wipe Cache Partition.

if you not done yet then do some settings to save more battery life and observe for next 1-2 days, it will give a noticeable difference

1. Connection>more connections settings> disable nearby device settings

2. Location>improve accuracy >disable
A. Wifi scanning
B. Bluetooth scanning .

3. Device care>battery >power mode>select "optimised" and "adaptive power saving".

And then click on "app power management >
And enable these 2 options.
A. Adaptive battery
B. Put Unused Apps to Sleep.

4. Long press on each app specially 3rd party(LIKE FACEBOOK, INSTA,YOUTUBE) and rarely used apps and also ON "GOOGLE APP" as well, then click on>app info> then go to these 3 options below on by one

A. Mobile data> allow background data usage>off

B. Battery >allow background activity >off

C. Notification >disable unnecessary notifications like promotional and unnecessary reminder notifications.

5. Go to settings >apps>search "weather" >click on settings icon right side > change "auto refresh" settings as per your requirements and disable some unnecessary reminder. ( due to auto refresh it continuously consuming battery?)


6. If you use Facebook frequently then disable "auto play video"
And if you are mostly uses mobile, on wifi connection then also disable "auto play videos" in YouTube.

if battery draining is new only after update with same settings and usage as before then no new settings needed.. just a calibration problem.
1. clear cache partition
2. drain the battery completely until it doesn't turn on.
3. charge the device to 100 in switchoff mode for good results.
4. again drain and charge again for 100. do this twice.
5. once done use your device between 20-80% for better battery life.
