Battery Life

[Daniel87]

Any one notice there s21 ultra isn't lasting a day? 

Before the update I'd get a day and a half roughly 

Now I'd be lucky for it to last untill lunch time.

Mine lasts 2 days plus. Check your battery stats and see what's eating your battery as that is abnormal use. If you are using any Social media apps, they are likely to be the issue. Most barely worked with Android 11, let alone 12.
