Hi, I've updated to Android 14 based Funtouch Os14 on my IQOO 9 5G device and I'm here to report a bug. 

The software version is : PD2136F_EX_A_39.7.7

I'm seeing the app battery usage for most of the installed apps are getting overriden by the software and are setting to 'Unrestricted' which causes unwanted apps to run in background and thus draining more battery. I've seen this issue discussed in various forums and thus once I updated to A14, I checked for apps battery usage and all was set to "Unrestricted". I've changed the priorities for apps that has to be left unrestricted to make sure they work in background and others to 'Optimized'  or 'Restricted'. And after a gap of 24-48hrs, I noticed a serious drain and ran through all apps once again and found most of them are reset to 'Unrestricted' again. 

I know this is a beta phase. Kindly work on this bug before you release a stable one. 

Thank you!
