S23 Ultra battery drain after February 2025 update

Stigeh — Wed, 05 Mar 2025 18:16:29 GMT

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 — Thu, 06 Mar 2025 07:29:01 GMT

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. 🙏

allan20166 — Thu, 06 Mar 2025 07:33:03 GMT

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

Re: Re: Re: Re: Re: S23 Ultra battery drain after February 2025 update

Piper123 — Thu, 06 Mar 2025 07:34:43 GMT

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

Re: Re: Re: Re: Re: Re: S23 Ultra battery drain after February 2025 update

allan20166 — Thu, 06 Mar 2025 07:42:14 GMT

S24 ultra series where the first to be blocked using these codes ever since Samsung wants everyone to use Samsung members app to run diagnostics

Some Older phones like s23 s22 series and A series phone will still use these codes but any new phone going forward will use the app for diagnostics

Works fine in my S25 Ultra, S24 Ultra and S23 Ultra but hey, you work in a shop so we will all assume you know best.

Thanks for your input.

allan20166 — Thu, 06 Mar 2025 07:55:53 GMT

Dude don't sit there and try to intimidate me because it won't work because you think you know better when you don't, these codes haven't worked over the past 2 months and that's on a mix of SM S24 and SM 24ultra SM25 and SM 25ultra aswell as SM A53 SM A54 and SM A55 including SM A05s= a06s and A16 all which have been verified with Samsung because the codes are not expected to work it's all gotta be done on the app.

Odd, still seems to work fine on my Note 10+ 5G, S21 Ultra and S25 Ultra. Even works on my non-phone Tab S8 Ultra. Better yet, it works on my Galaxy Watch 6 too... 😂

Same here. Hopefully the battery stats reset works for me

S23 battery life after February 2025 update

Truckdude239 — Sat, 08 Mar 2025 20:45:13 GMT

My battery life after the February 2025 update has cut the life in half, I use to take the phone off the charger at 7am and not have to plug it up till around 930pm even with heavy usage, now I have to charge my phone during the day.....

Anyone got any ideas on how to boost the battery life back up, or is this more of the planned let make the phones obsolete so they upgrade?

Re: S23 battery life after February 2025 update

Hello 👋 @Truckdude239

First please use the optimisation option in your device Care section.

Then under the battery section look at what apps are using your battery and take appropriate action such as using sleep or deep sleep or remove the app if its not needed.

You can clear the phone's System Partition Cache Files Section too.

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 }

May I suggest to perform a forum search as you may find already existing threads with help and advice within.

Is there a fix for this or is this typical Samsung forcing you to upgrade

Re: S23 battery life after February 2025 update

Rraykov — Sun, 09 Mar 2025 10:41:13 GMT

If they don't fix this the only upgrade I'll be making is is switching to a phone that has a very distinctive logo in the shape of a fruit and a number 16.
