Fold 4, UI 5.1 battery drain

[Beershark]

Since updatingnto UI 5.1 noticing the battery drains very quickly.

Not running any different apps, use App Killer to close background tasks. 

I don't use Samsung Keyboard, even though installed, I use MS SwiftKey 

I hear other users are having the same.... 

Anyone else here have this problem. 

EDIT.

For clarity, my battery usually lasts comfortably a day under normal circumstances.  When home, I often play Warpath for a few hours on and off in the evening.... Again, battery usually lasts until bed time.  

Post 5.1, I need to recharge battery about twice in an evening (not to the 85% limit I set, but close).

I have now completely reset the Samsung Keyboard and deleted everything.  Restarted phone, when restarting I saw a new splash screen saying "5.1 optimising apps".  

Last night seemed better.

Have been on One UI 5.1 for a month and am loving the battery life on this update.

After updating did you do the following?...

Wipe Cache Partition, Repair apps & Galaxy App Booster

I've performed the Clear Partition and Repair Apps, but not the Galaxy App Booster (didn't even know something like this existed).  It's not available in my region (Canada) but I'll try via APK mirror to see if anything changes.  Thanks!

This is the eu.community, (Europe), section of the Samsung forums for the Fold4, F936B, and Flip4, F721B models and firmware.

You may have a better response for your Canadian model and firmware of Fold4, F936W, or Flip4, F721W, over on the Canadian section, here...

Okay will do, thanks. 

Just wanted to say that I did sideload the Galaxy App Booster APK and it seems to have worked like a charm.  My average battery usage is back to 4.5%/hr again.

Glad it has worked for you. 

It is best practice to do this after a major update as it can right a lot of wrongs without having to Factory Reset the device.

Strange that Samsung's own Good Guardians and Galaxy App Booster are not available in the Samsung Store in Canada.

Is same to me, after my Fold 4 after install to OneUI 5.1, i find out my battery start drain faster compare before upgrade. And phone are generate more heat.

[Beershark]

Did you try resetting the keyboard... That seemed to work, strangely enough.

[Edment Tong]
