Rapid Battery Drain after UI5.1 Udate

[philipos]

Hi all. 3 days ago I updated the software on my Galaxy ZFold Flip 3. Now the smart phone becomes very warm & the battery does not last anywhere near as beforehand. 

The smartphone now gives audible alerts & there are no alerts I can find.

The smartphone has changed all the calender reminders to 10 minutes from 1 hour.

This flip 3 is the 2nd one I have had & it is about 10 months old, the first one I had the screen protector fitted by Samsung came unstuck on the fold. The first one was only 6 months old.

Has anyone else had this latest issue after software update?

Try wiping the phones cache partition in recovery mode.

Hi Fiona26. I just did that after my first post. Let's see what happens now. I am about to do a power off & on again. Thank you

What does the device care say and does it indicate what is causing the battery drain. Before I list the probable culprits.
