I had the same thing after a clean install. Maybe its the same after an update. Android system consumed most power, this stopped after approx 9 days and the battery life went up. Just give it some time to do its thing in the background and the battery life will be like it was. At least that is...
Pinch homescreen -> widgets -> search glass thing top right corner -> Android widgets bottom screen. The Android widgets including calendar one is in there
I am on Mi11le Lisa, standby drain is the same. clearing Play services cache and data helps for some time. But after a while the drain will be back. Could be placebo though. Maybe battery backup on Lisa just isnt that great.
Thanks! I installed the previous version 14.0.6.0 via fastboot and got twrp installed with it. The re-uploaded rom got updated via twrp and all went without issues. Thanks again
Mi 11 lite 5g ne Lisa, I am on latest 14.0.6.0, updated via fastboot from 14.0.5.0. I have theme reset to standard from time to time. I only apply Icons, and these are reset to stock after a while.
