Battery related issues after One UI 4 update

[S_Kumar73]

After One UI 4 update the battery getting drained very fast. (Folks don't comment like do wipe cache, wipe data etc.. I even did factory reset after the update. Infact I didn't even install all my previously used 3rd party apps except whatsapp). Previously in thr battery status it shows "A full charge last about 24 hours. Now it shows "A full charge last about 13h 45m only". Samsung spoiled the battery life by giving half baked software update.

Also note, after a major update, any phone requires 5 to 7 full charges to calibrate battery usage meters. This is stated as such on every screen that shows battery capacity.
