Power Drain

[Fooey]

4 hours of light use and the battery of the s21 ultra at 48%. Very light use. Seen one app used 25% so uninstalled it but surely that battery drain ain't normal?

Always after an update
A good idea is too clear cache

There I an update available...seems to be fixing quite a few peoples issues

This way you keep posting to clear cache partition is wrong....its for phones running android 10 not 11 or 12...android 11 and above need to have headphones plugged in or be plugged into a computer 🤔

Hmmm l on android 11 on mobile a41 and clear my phones cache regularly and don't have to put my headphones on the phone to clear cache

After my note10 updated to android 11 it had to have headphones plugged in and the same for my S21 ultra....yeah maybe it still works that way for some phones but definitely not Note10, S10, S10+ and S21 series

As far as I am aware from Android 11 onwards  on  Exynos devices phone must be plugged into computer or USB-c Headphones connected in order to access the Recovery Menu.  I do not have  experience of A series devices though.  Apparently the reason  was so that  the phone was not booted in error.  some more information here https://piunikaweb.com/2021/01/09/samsung-devices-on-one-ui-3-0-android-11-update-now-require-a-usb-...

I need to connect my s21u to my tablet via USB to access that menu.
