I'm having a similar issue, max 4 hours screen time. did you use smart switch to transfer data to the S21U?

I bought it too and got it by 27 Jan, The battery life so far is **bleep**. I have to charge it twice a day and all I do is WhatsApp messaging and camera usage sometimes. It is the worst battery life so far , it says it is learning usage patter even though it is learning but it should have been good on the first place. it has 5000 Mah battery. Cmon..

someone said reset the phone without using smart switch.
anyone used that donot want to format the phone

[VijayKM]

should we return the unit because every YouTube reviewer having exynos version had a great battery life.

May I know why u receive phone earlier?

This is normal for start, as your phone is learning your usage pattern. Once that phase is done your battery life should be stable.

I've had the phone for a week now and the battery life is pretty bad, barely getting 4-5 hours SOT. I cant make it through a full day with basic use, clearly some software issues.  My 2 year old Huawei Mate 20 pro has similar battery life.
