High Battery Usage on One UI V7.0

[RedDogRabbit]

If you're seeing the battery take a hit on the April Security Patch Update, you aren't alone.. 

Sammobile says that "it's nothing to worry about", maybe.. if it's fixed in the May 1st Security Patch Update... but right now it's more than a little annoying. 

From when I received my S25 Ultra, the battery life has dropped by 20-30%

I've Toggled OFF AOD, and slight improvement, but System UI and Play Services are still using more than when I got the S25 Ultra. 

SammyFans also reports similar observations.

So for those of you who are desperate for the One UI V7.0 update.. be careful what you wish for.. unless Samsung has resolved the battery problem!

Normally when just setup a new device with fresh new software updates the background processing may take up to 1 week to finished

It's got nothing to do with time, it's based on charge / discharge cycles.. maybe 2 or 3.

This battery issue is a software problem, not a battery settling down scenario.

In this case, it's definitely not a "you thing". It's a Samsung thing.. period.

Strange but I haven't seen the same battery fast discharging on my S25 Ultra that you are having.
I have not been using mine to near the screen on time as you but is about the same since I got the device and really not noticing any problems

[RedDogRabbit]

I had been easily getting 20+ hours on a full charge, now it's down to around 13 hours.. I haven't changed my usage, and I've really noticed it since the April 1st Security Patch OTA.

And apparently, I'm not the only one.. as illustrated in the links from Sammobile & SammyFans.. 

Often I am asked if I work for Samsung, as I am frequently defending them, but I defend when I see what I feel are ridiculous positions, but I have never been shy to criticize either...

I trust Samsung will fix it in the next patch. In the meantime, its all about power saving

No change in battery life for me since the April security patch.
