Why is it my phone only shows battery usage on screen time yet i use quite lot of app
Guess nobody gives a damn about this issue huh??
Not sure. That reporter is notoriously inaccurate however, I recommend you not rely on it for the baseline battery monitoring.
If you are really dead set on using that, try a reboot and checking the settings within Autostart Manager.
