Hi, I don't have any battery issues with some Tips, Please make sure to wipe the cache Partition. Step 1: Connect your Galaxy S21 Ultra to a PC using the original USB-C cable
Step 2: Power off the device using the side key or the
power icon in Quick Toggles. Step 3: Press and hold the volume up and the side key.
Release them when the Samsung Galaxy logo appears on the screen
Step 4: Use the volume-down key to highlight the
"Wipe cache partition" option. Press the side key to select it.
Please always keep Power saving mode ON.
Check background using batteries Apps and third-party apps draining faster batteries.
Close background battery using Apps when it is not in use.
Thank you for discussing this with me 😊

Is it compulsory to connect the phone to PC

Lol, either we need to connect to the original Samsung S21 Ultra charger. All the best for wiping the cache partition is completely good to connect with a PC. Even a PC uses it to install a reliable driver and software to upgrade other smartphones. Thank you for discussing this with me and giving the best discussion 🥰.

You do not need a cable. Go into your settings and search for "side key". Set it so that press and hold is power off instead of wake up bixby.
Now you can get to the recovery menu like normal.

We are discussing clearing the "wipe cache partition" to fix junk data & fixing issues.
