Read through this thread, and I just wanted to add a few things:
- Is Bluetooth on? If you are using your S22 Ultra in tandem with a Galaxy Watch or a Galaxy Buds, it will impact your battery life.
- Are you using any power-hungry apps in the background? Make sure to clear all background apps every now and then as they may contribute to battery drain as well.
Otherwise, if it is a major concern, you can always reach out to our customer support. I think it'd be better if one of our technicians got a closer look at your device :)
You can book an appointment through the Samsung Members App. Just visit the Support tab and scroll down to "Book appointment."
