S23 Ultra battery drain after February 2025 update

[Stigeh]

I have always had Samsung phones and updated as soon as possible, but after updating my phone today my battery is draining very fast. Before the update my phone could have 80% and next day with little use, 40%. After update today 80 %, now 6 hours later after hardly any usage, 17%. Something must have been badly wrong with the latest update! Samsung please fix either roll back or fix the current update!!!

Hello 👋 @Stigeh 

As a process of elimination please try this generic troubleshooting step >

Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port or a usb-c to usb-c phone to phone set up to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

The update won't be rolled back but if there is an inherent issue then Samsung can be advised via feedback in the Samsung Members App. 

If i can be of any further help please don't hesitate to ask  😎

Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum

Please press on the good button in device care to close apps that don't need to be on in the background.

You can also do a battery reset using Samsung Phone App.

This has been asked several times recently.

Dial *#9900# then scroll down to battery stats reset. Click then restart your phone.

Samsung blocked the codes for diagnostics because people like you where handing them out and you shouldn't have been.

[Piper123]

Ate you using Google Phone App or Samsung Phone App?

Only works on Samsung Phone App.

And it does still work as I use it every time I've had an OS or Security Update. 🙏

Dude I work in a phone shop I use these codes on the daily too but ever since the update they have never worked again, Samsung has blocked them

[Piper123]

Kindly explain how I and others are able to use them?
