Does anyone has any issued after the new UI 7.0 update?

After I updated my phone, the battery drained rapidly - after 3 min of use I went from 100%-75% and now after 24h of the new update, my phones shuts down unexpectedly and goes to 0% when it was just at 96% second ago. 

I keep on having to charge my phone to use it and without charging it, it won't even last 5min. 

Can someone help please🙏😭😭😭

Edit: For anyone that has the same issue as me, I waited 4 days and tried everything but nothing helped, so I had to go replace my battery because the old battery just kept getting worse. The battery is now back to normal, and 94% lasted me 25h with bare minimal use on power saver.
