I just bought my S20FE 5G few days back . After charging 100% I'm seeing a drop to 94 % within 10 mins usage .

I bought my device S20FE 5G few days back.  The battery drains way too fast from 100% even without usage . Should I return the device . The replacement is just for 14 days . Should I wait or get it replaced ? . @samsung

Bit of a drop but put power saving on gives you an extra 3hrs

@MADHAV As your device is new, this is expected. Your device is learning your usage pattern so that it can optimize the battery life based on your performance, this may drain the battery quicker in the first few days.

It will get better but not by much, the battery is worse than my now old batteries in my s8+/s10.

I have multiple bixby routines micromanaging my phone functions to improve battery management and this phone still doesn't being used as my old one did (and still continues to do so for my family members).

Replacing it will yield the same results I'm afraid.

It really depends on a lot of factors. Your display brightness setting, what apps you've downloaded and their sync settings for a start. Like the Moderator has mentioned, it is still learning your usage pattern and will make optimisation adjustments after a few days.
