Turning off battery optimalization

Hello,
I cannot seem to find how to turn off battery optimalization on my Fairphone 6 with the latest update of Android 15 from 5th of July.

I have searched for different steps, which mostly guide me to Settings->Apps->[Name app] and so on. Except for battery usage for an app and allowing it for background usage, I do not see any settings for battery optimalization. Also, if I search of words like ‘Optimalization’ in settings, nothing comes up.

Does anybody else experience this? With my older Fairphone 3 I did not have this problem.

Kind regards,
Karim

Settings->Apps->[Name app]->App battery usage-> click Allow background usage → unrestricted

Aaah, I see now. Wow, so simple… When at the ‘Allow background usage’ screen, I thought I could only click on the slide to turn it on/off, but now I see that that is actually also possible to click on the settings itself. Thank you!
