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.

Many users have reported serious battery drain problems after upgrading to One UI 7: What could be happening? Here are some ways to reduce idle battery drain:

Why One UI 7 Could be draining your battery

• Background processing: This update may have caused system apps or third-party applications to run more frequently in the background.

• Battery Optimization Reset: Certain settings (like app sleep or restricted background use) may have been reset.

• Badly optimized software It is possible that the firmware has bugs which cause unnecessary CPU wakeups or sync issues.

• System caching & reindexing After major updates the phone may take up to 24 hours to complete background optimizations.

What you can do right now

1. Restart Your Device - Simple but can stop buggy background process

2. Check Battery Use: Navigate to . Identify any apps that drain battery in an abnormal way.

3. Put apps that are not in use to sleep : Use the "Put Apps to Sleep" and "Deep Sleep" options under Battery Settings.

4. Clear cache partition for Samsung phones

   • Switch off your mobile phone.

   • Hold Volume Up + Bixby + Power (if available) and wait until you see the Samsung logo.

   • Select Wipe Cache Partition using the volume keys.

   • Reboot.

5. Update apps: Minor updates are released to fix some battery issues after the One UI release.

6. Disable Location, Always On Display or 5G if needed.

Still Not Fixed?

If battery drain persists after several days or, even after you have tried the fixes:

• Report it via Samsung Members app: Include system logs.

• If you think that the hardware has been affected by the update, visit a Samsung service centre.

• You can request a rollback, although it is not supported everywhere.

You are right to be frustrated. Battery drain when the phone is idle is not acceptable, especially after an update. If this was caused by a faulty OTA, Samsung must take responsibility. Backup your device in case you need to perform a service or factory reset.

My battery is still the same on OneUI 7 as on 6.1... but that's on my A16

Does anyone else have the problem of every time the phones update they seem to have worse battery life. I took my phone off the charger at 530am. Sent 4 text and by 630 was at 93 percent. Each update seems to do something to the battery to make it less valuable. I don't understand and its very upsetting. I have to use my phone for work everyday and my battery is at 30 percent by 3pm. This is nuts.

I was told for the s24 that the cause was Instagram. Not entirely sure that I believe that.

Thats a load of bull. I aint done nothing and its drained.

My sentiments exactly

[userEYPDXX9hhY]

I thought It was just me. After this last update, my battery life is abysmal. Yesterday at 8:30am. I was at 100%. At 4:00 I was at 20%.

When they rolled out the 7 ui, that's when I started problems. Plus now my phone get extremely hot when I am charging. Never happened before that update.

[userEYPDXX9hhY]

Mine is getting hot as well. I've been shutting it off during the day for 15-20 minutes.

Mine gets hot during the day while working. Yes im outside but I stay in the shade as much as possible. I have to put my phone in a cooler every chance I get. This just aint right
