  • Battery only lasts a few hours, have 3 apps Pixel 9

I have Signal, Scalable Capital and Tidal installed, have limited 69 system processes to save battery, always turn off mobile communications and only use WLAN. I have revoked the permissions for all apps.
Although I only have the standard apps from GrapheneOS and the 3 apps already mentioned on it and always have energy saving mode, WLAN, NFC, Bluetooth off, the battery lasts 6 hours, brightness is already very low, In confidential mode, I have all the important apps Sparkassen APP Bank and Insurance App, i use confidential mode not and it is deactivated, 99% of the time, all of these apps are always closed, right? Because i dont open the confidental Mode.
I have a Pixel 9

    Rooouug have limited 69 system processes to save battery,

    There might be your problem. Limiting certain apps and processes can actually increase battery drain. I would just leave everything at default settings for system apps.

        n3t_admin I have measured again with the APP AccuBattery since I switched all system processes back on I am at 57℅ and according to the APP the battery still lasts 3 hours. I don't have any apps running in the background

            Rooouug in that case I would recommend a factory reset. Make backups of everything on the Pixel, then perform the factory reset (you can do it via settings, no need to do it in recovery mode). When you set up the phone afterwards, don't touch any settings. Just install the apps you had before and check how it goes.

                As already stated on other posts..
                You need to approach this battery diagnosis one step at a time.
                Firstly If you are able, (your phone is not your daily driver). Factory set set it, and just run GrapheneOS for a day or so. If it operates as normal, introduce one app at a time, until you find your problems. If however it misbehaves with just GrapheneOS, then re install stock android and see if it misbehaves with that. If so then it may be a battery problem.
                Chopping and changing app settings at once is a sure fire way to confuse.
