Very bad battery life after One UI 7

[Geopan8800]

I'm sure there are many of this, but I can't believe how much the battery performance has worsen since the update. My phone is on 50% by noon after some music playing, 10 15 min tiktok.... Nothing basically...

The May update didn't seem to hold anything related to battery performance. 

I hope Samsung fixes this ASAP. 

I always have the newest Ultra and been fine with occasional top ups of my battery in the late afternoon. As I consider myself a medium to heavy user. But this is unacceptable now on the S25 Ultra, less than 5 months since launch... 

Next year I'll definitely have to reconsider if I'll stick to my loyalty to Samsung. Some of their competitors are already trying new silicon batteries but even without them, they seem to offer a better battery life.

I am having the same issue... read online that it might take a while until the system reprogrammes itself to the daily usage of the phone, and from there adjusts the battery performance...

Have you been into settings and battery to see what's using an unusual amout of battery life.
Make sure all your apps are upto date. Playstore and Galaxy Store.

Be worth Wiping the Partition Cashe on the phone as well

Yeah, I saw this and it sounds like tons of BS... It shouldn't be the case especially for flagship owners

I have the same problem in the future and it will come back.

Tbh, tons of Pixel users are experiencing this too. Wouldn't be shocked if this was due to Android 15 (Google).

Samsung batteries do, in fact, calibrate over the first 14 days—personal testing done

This has been posted about already; be sure to check out the forums for troubleshooting.

Didn't experience anything like this with the latest May update. In fact I found battery life stability to be better than before. Even YouTube seemed to be playing nice compared to before, which was a terrible battery drain for me prior.

Don't know, just got lucky the beta today of UI 8 and Android 16

Same issue...any update regarding one ui 8 ...any change for battery drain

Just installed it. Over 3GB. I'll give it a few days. Obviously it's Beta so I'm taking the risk. Never done Beta programs before but One UI7 was too bad.
