S23 ultra battery draining fast after One UI 6.0 update

[JAbid]

The problem started after updating my S23 ultra to One UI 6.0. 

Earlier, my phone's battery would last around 36 hours on heavy usage. Since the update, the battery performance reduced to 24 hours.

Since the One UI 6.1 update, battery life has become miserable and lasts for mere 10 to 12 hours. 

Battery life was one the main reasons I bought this phone, Seems my loyalty with Samsung nears its end. Time to switch to Apple.

Yes! I thought I was losing it! I have to keep battery saver on all the time. My nfc sent random ping sounds after this last update. All my notifications are messed up when I did a reset of those trying to find the dumb sound. I swear they better not be trying to copy Apple and killing phones. Lawsuit!!

I have done all of the above and even done the hard factory wipe (which was ultra frustrating and cost me a lot of data loss) with no avail. Now the battery doesn't last even last 8h on my S23 Ultra. I will have to revert to Apple as the battery as well as camera performance were the deciding factors for Samsung. Never again.

I turned off the always on display, deleted internet and chrome (internet ended up staying but I swear I deleted it). Then deleted Facebook as well. I've used 34 percent with screen on time of 2.5 hours and off time of 8 hours. So it seems to be working.

You can do the same by hard resetting it manually and reboot it to boot loader not resetting your phone you only wipe the cache. No computer needed.
