Battery backup

[Suhayel_hossain]

Since the April update, I have been getting noticeably less screen-on time. Before the update, I used to get around 8 hours from 100% to 20%, but now I only get around 6 to 7 hours.

At first, I thought it was normal and that the phone would take a few days to optimize after the update, but the battery backup has not improved at all. I do not understand why it suddenly dropped so much.

Is there any chance the next update could fix this issue, or is this the kind of battery life I should expect from now on?

I recently switched to Samsung.

Device: Samsung Galaxy S25 Ultra Global Variant The phone is official and around 1 year old.
