Z flip 5 battery drain

[Sukriti]

Hi. I updated my phone to UI 6.1. Immediately after the update, my battery started draining extremely fast. Now my phone drains even all the apps are closed and phone is locked. Doesn't last even a single office hours duration. 

How do I roll back the update? 

How to fix this battery drain issue?

Hi @Sukriti 

Once the update and been downloaded and then accepted, your not able to rollback to the previous software. 

Please try these troubleshooting steps. 

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. { Repair Apps may not be availableto the Samsung Galaxy s²⁴ Series of phone's. } 
• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 
• Use the optimisation tool found in your Samsung Device Care. 
• As a last resort back up and factory reset. 

If I can be of any further help then please don't hesitate to ask.  😎
