Performance issues ANDROID 15

[lost_traveleros]

After the most recent Android update, my phone's performance has taken a serious hit. Everything feels noticeably slower—apps take longer to open, there's frequent lag, and even basic actions like scrolling are choppy and delayed. On top of that, the battery is draining much faster than usual, even when the phone is idle.

I tried a full factory reset hoping it would resolve the issues, but unfortunately, it made no difference. Whatever changes were introduced in this update have significantly degraded the overall user experience.

I strongly urge the developers to address these performance and battery problems in the next patch. As it stands, this update has made my phone frustrating to use.

Let me know if this helps.

It's a long shot, but don't you have by any chance Google Reading Mode installed? For me that one caused most of the animations and transitions to be very badly choppy as well as frame drops in videos etc. Once uninstalled it, everything went back to normal. I have the latest Android update and have 290 apps installed on my phone but have no performance issues, except one: occasionally (about 1 in 10) when pressing the physical power button it takes the phone up to 3 seconds to show the lock screen, and then another up to 3 seconds to unlock which is like 5x longer than normal - this I only experience since the latest update.

Also, Samsung Secure Folder can take a big enough toll on performance. And turning RAM Plus on can slow down some apps if you use a lot of apps.

I just updated my samsung A25, thinking it would significantly improve the overall experience,  just to find out that the phone has now a serious issue when it comes to fingerprint unlock,  over and above the stated issue, I encountered a significantly higher battery drainage.  Please attend to these issues as soon as possible.

Same thing for both of my Tabs and my Z Fold 7. I have the Z Fold 8 being delivered today, if it's happening on that one too I'm not sure what I'm going to do. I have 3 high end Samsung devices and every single app, from FedEx, UPS, GE, CNN to my bank and others will not open or they take several minutes to load. This all started after the last update from Samsung.
