S25 Ultra - Battery life affected after 1st Software update

[S_Kumar73]

Two days back Samsung released 1st Software update for S25 series. I updated my S25 ultra and tested 2 charging cycle. 

Before the update I got 9½ to 10½ hours Screen On Time. But after the Feb 2025 update the SOT reduced to 7 hours. Almost affected 3 hrs of SOT.

Before Software update 

After Software update 

Also before update i checked 5% to 1% and the SOT is 28 mins. Now only 15 mins. 

Pathetic update.
