S24 Battery Drain Post-Update

[Jay_Q]

I updated to one UI7 last night and now my battery while on idle is draining extremely fast. 

Had I known this would be an issue I would have never updated to this crappy software. 

This is a major issue and like I said I can notice the extreme battery drain while the phone is idle.

If Samsung doesn't fix this issue I will be filing a claim as to me this is now a defective item that they caused.

I noticed my battery draining much faster after updating it. Is there a fix yet?

IS THERE ANY WAY TO UNINSTALL THIS HORRIBLE UPDATE????
I AM ALSO HAVING SERIOUS BATTERY DRAINING. 🤦‍♀️

Stop being overdramatic. You wait a week or so for the Battery to relearn usage patterns

I am sorry you are having this problem. I have the Samsung Galaxy S24 FE and my battery life has increased. No battery drain problem here. @MatthewReiter has given you sound advice. Your phone will learn your usage pattern.

Many users have reported excessive battery drainage. A few things to keep in mind:

1. It's a new OS. It will take time for it to relearn usage patterns, as has already been pointed out. This can take a week or two.

2. People tend to use their phones more after such a large update (trying to figure everything out), even though they may think they're not.

3. If you haven't done so yet, clear the device cache partition. I'll list steps separately. This partition contains cached system files from the old OS and needs to be manually cleared so the new OS can generate its own files.

That said, now that the update is more widespread and more users are reporting in, they're starting to figure out that the battery drain primarily affects S24, S25, and foldables users. As stated in this article, "A fix is expected in the May 2025 update, addressing software bugs causing excessive power use."

Just so Samsung sees more complaints, this last UI 7 update uses almost 100% more than usual. I have the max battery protector on and it always start the day at 80% and ends up in the middle 60% range. It now ends up in the middle to low 40% range every day. It been going on for three weeks. No social media on this phone. Texts, email a few times a day real quick and quick looks at news and weather. All the apps I use show < 5% total battery use. Your QA testing should have caught this. Or it did and you're not admitting it. Please fix your code.

This is a user-to-user support forum. Samsung isn't reading everyone's complaints to figure out what they should fix. You can submit feedback that they actually will get by going to the support tab at the bottom of the Members app and sending feedback from there.

Did you wipe the cache partition of the phone? That could help your problem. Here are the steps:

1) Turn off your device.
2) Press and hold the Volume Up button and the Side/Power button until you feel a vibration and the Samsung logo appears. Let go of the buttons.
3) You will now be in Android recovery. Use the Volume buttons to highlight "Wipe cache partition."
4) Press the Side/Power button to execute.
5) Use the Volume buttons to highlight "Yes."
6) Press the Side/Power button to execute.
7) "Reboot system now" will already be highlighted. Press the Side/Power button to execute.

Since the recent system upgrade, I've observed a significant decrease in battery life.
