Fast battery drainage since Feb and March 2025 updates. March 1st update makes it much worse !

[marcovth]

The Feb update was already bad, but the March update is even worse for battery drainage.

The s23 was updated yesterday with the March 1 update. After 3 hours it went from 80% to 0% shutdown.

This morning, it went from 100% to 60% in 2 hours. The phone was warm. All apps we killed.

I then turned off the Wifi, and the battery went from 60% to 58% in two hours.

The Wifi is really the problem. I noticed the same in February during my vacation that I had to turn off the wifi because it was constantly reconnecting, making the phone hot, and draining the battery.

But at home, all was fine until yesterday with the March 1 update.

Can you check your used apps. Does YouTube feature on the list?

[marcovth]

I turned off all the apps at 100%. I even removed my anti-virus app at 100%, because it took 5-20% of the charge during previous days. 

I don't have youtube installed. I prefer to use YT via the Brave browser because Brave kills the ads.

Do you clear your phone cache partition after updates?

[marcovth]

I don't know what a phone cache partition is, and I should not have to know what it is. Samsung introduced the wifi battery drainage problem, and Samsung should fix this problem as well.

@marcovth: While I do appreciate your viewpoint, wiping the phone's cache partition can be an effective means of improving the performance of the device, and resolving any temporary software issues. 

To proceed, please power off your phone, connect it to a home computer via USB cable, then press the Power and Volume Up keys together until the Samsung logo appears on screen. Release the buttons at this stage, and you should see a Recovery Mode screen. Using the Volume Down button, scroll to Wipe Cache Partition, and hit the power button to select it. Select 'Yes', then scroll to Reboot System Now on the Recovery Menu, and tap the Power button.

Let me know how you get on.

Alright, done. It's 17:02h and battery at 89%. Will check in an hour.

[marcovth]

18:38h, 85% ... I will test another wifi connection.

[marcovth]

21:06h, 82%, so normal again. Thanks.

I've also been experiencing battery drain just recently on my tab s9 FE. My friend's also been saying the same thing on her s7 FE, but hers is worse because she's had that tab for 3+ years now. I used to be just scrolling, viewing, and annotating pdfs and I could go for more than an hour and have a 1-2% battery drain, but this past 1-2 weeks, that number goes up to about 4-5% drain per hour. Even when I'm not using my tab, it drains faster than before. I've seen other Samsung users report the same thing recently with their phones and tablets.
