One ui7 update

Anyone else having really fast battery drain after the update? I lost 14% during 6 hours sleep with all apps closed. I've lost 6% in the process of looking into the problem in 5 mins time

Using the Samsung Phone App (not the Google one)

Dial *#9900# then scroll down to battery stats reset. Click then restart your phone.

Make sure Auto Blocker is turned off when doing this

Aside from the information @Tourbillion De La Vie provided you now need to connect to computer ,other mobile or for instance TV USB with USB-C cable. This is recommended after updates,particularly major OS updates. Do though also try the Battery stats Reset as mentioned by @Piper123.

Hey all, I have done as y'all suggested, twice. It has improved my battery drain, but it still isn't lasting as long as prior to the update
