Phone telling me apps need to be shut down due to power use

[AzureVice]

I woke up this morning and it was saying an app was using a lot of CPU power and when I clicked it it said android 12 itself was the problem using 23% CPU

After that happens my wallpaper on the home screen completely blurs out.

Also noticed the phone gets hotter than before

Using an S21U unlocked

My phone did the same thing. Then, I factory reset my phone. I don't have that problem anymore

That seems drastic..woulda cleared the the system cache before that.

Just backup your phone

The mod suggested the same thing..it takes a few minutes to do instead going the reset route.. that should be a last resort. But I'm glad it worked for you.

Hello @AzureVice ,

We would recommend clearing cache of the device 

1. Turn off the device.
2. Press and hold the Volume Up key and the Side key.
3. When the Android logo displays, release both keys.
4. An 'Installing system update' message may show briefly before the Android Recovery menu options appear.
5. Press the Volume down key several times to highlight Wipe cache partition.
6. Press Side key to select.
7. Press the Volume down key to highlight Yes, then press the Side key to select.
8. When the process is complete, Reboot system now is highlighted.
9. Press the Side key to restart the device.

If issue continues to happen even a day or two after clearing cache, Please send us an error report from the Samsung member’s app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
