Here is the battery backup I got after July update. I updated using smartswitch it took 36min as you can see my mobile charged 2% from laptop.
I played Wcc3, used insta, Samsung members etc. The result I got
Usage: 10hrs 15min
SoT : 9hrs 23min
Also battery was not draining much at night
Just 4% in 7hrs 34min sleep.
Overall deep sleep drain was just 5%.
Some more SS
Only thing I observed was between 20-25% mobile became slow and got hang issues. Back to normal below 20%. It is not recommended to use below 20% as it will affect your battery life. This is just a test and I do it only 1s after a update. Generally I keep my mobile charge between 20-80% and during testing 0-100%.
