It might be because of your network provider has not properly optimized the network. If you are using Jio SIM and not living in 5G coverage area then select your network as LTE Only mode until stable 5G launching your area. It might help to resolve your issue. Otherwise, you can take a backup and factory reset the phone to solve the issue hopefully.
Select the Network as LTE Only or 4G/3G/2G Auto and restart the phone and try testing, hopefully it will resolve your issue. I am using Same S22 Ultra with Vi SIM but I don't have any issue and my battery last until 2 days so there is no any issue with software side. Also ensure your phone updated with latest software update with January 1 Security patch.
We acknowledge your query and apologize for the inconvenience caused to you and will surely assist you regarding the same. And please follow the easy troubleshooting steps which might help to solve the issue.
