Abnormal battery drain

[userpojeebF2lP]

I'm experiencing abnormal battery drain courtesy of "downloads" and.I can't figure out why this is going on.

Anyone have ideas as to potential solutions?

Just my 2 cents I think the x isn't the issue as that's listed 3rd the downloads is the mystery try tapping that and see if it shows anything

Go to the device care app and set performance profile to light.

Yes, many Galaxy S24 users are noticing faster battery drain after the latest One UI 7 / Android 15 update. It’s not just you — several posts on Samsung’s community and Reddit report the same issue. After major updates, phones often run background optimizations and re-indexing, which can temporarily cause high battery usage. Some apps (like Instagram or Samsung Health) may also misbehave until they’re updated or re-optimized.

Here’s what you can do:

1. Wait 2–3 days — the system may stabilize on its own.
2. Check Battery Usage (Settings → Battery → Usage) to find any app draining power.
3. Clear Cache Partition from Recovery Mode — this often helps after updates.
4. Restrict background activity or put heavy apps in “Deep Sleep.”
5. Disable unused features (5G, Bluetooth, NFC, Always-On Display, etc.) when not needed.
6. If the issue persists, backup and factory reset — a clean install can fix leftover software bugs.

Samsung is reportedly aware of post-update drain and may release a patch soon. For now, optimize what you can and give the phone a few charge cycles to relearn your usage pattern. Most users say performance improves within a week.

Many Samsung Galaxy S24 users are reporting rapid battery drain after the latest software update. This issue appears to stem from background processes, app re-optimization, and potential system bugs in One UI 7. While some drain is normal right after an update, it should stabilize within a few days. Users can improve battery life by clearing the cache, limiting background apps, and updating all software. If the problem persists after a week, performing a factory reset or waiting for Samsung’s next patch update is recommended to restore normal battery performance.

Yes, many users noticed increased battery drain after the latest One UI update. It’s often due to background re-indexing or optimization after installation. Give it a few days to stabilize. Meanwhile, restart the phone, wipe cache partition, and check for rogue apps or adaptive battery settings. It usually improves soon.

Hey TarunNagar,

You’re definitely not alone — I and a few others have noticed faster battery drain on the Galaxy S24 after recent One UI/security updates. A few things might be happening:

1. Background indexing & optimization: After an update, the system often re-indexes apps, media, and system data. This can cause higher battery usage for a day or two. Usually, it settles after 2–3 days.

2. Battery-draining apps: Sometimes apps like Instagram, Chrome, or Samsung Messages temporarily use more power after an update due to compatibility tweaks or cache rebuilding.

3. Settings to try:

• Turn off Adaptive Battery temporarily and see if it improves usage.
• Check Battery Usage under Settings → Device Care → Battery to identify unusually high apps.
• Restart in Safe Mode to see if a third-party app is contributing to the drain.
• Make sure all apps are updated to the latest versions compatible with the new One UI patch.

4. Warmth issue: Minor heat right after an update is normal due to background processes, but if it persists along with rapid drain, a soft reset or full cache partition wipe can help.

In most cases, battery normalizes after a few days. If it continues beyond a week, contacting Samsung support or considering a factory reset (after backup) might be necessary.

Hope this helps! Hang tight for a couple of days and monitor — the system usually stabilizes after updates.

My battery is lasting maybe 5 hours with heavy use with an 85% charge. The battery settings app shows a full charge last somewhere between 10 and 13 hours. That number used to be 16 to 24 hours. Phone temperature according to accubattery is typically between 87 and low 90° F (it's kind of cold in my place right now).

The heavy battery use started just before one ui 8 beta and then got much worse after the stable one UI 8 and then again after the November 1 security update. I've been consistently charging to 85% for well over a year now. I do a full charge to 100% from about 15% about once a month.

Heavy usage will lessen the time a battery will last

[userP1RGQBW3CK]

Jesus, are you serious? The one constant in the information I presented is heavy usage. It's not a factor for why battery life has deteriorated so much.

Well fact is if your online using a browser or games etc that affects the battery same on a laptop
