Experimental Mobian kernel patch for extended battery life

[teekay]

I'm currently testing a #Mobian kernel patch to improve battery life on the #PinephonePro and it's looking promising (about 3 hours of continuous use instead of 1 hour). If you'd like to try it out, assuming you are running Mobian, download the linked deb file onto your phone, install it, then shutdown your phone and remove battery, wait 10 minutes (to reset the battery meter), then boot into the new kernel. I recommend using this with Megi's uboot bootloader as you can then choose which kernel to boot into (6.16 is my patched one, 6.12 is the current Mobian one).

Note that suspend doesn't work in this kernel, I am looking into this. One additional bonus with this kernel is that if you uninstall the default Camera app, then install Camera from Flathub, it should work fine with both front and back cameras, you can take photos and scan QR codes and the image is not inverted on the back camera.

Let me know if you try it out.

What exactly does this do to improve battery life? Where is the source code?

It uses a "raw" state-of-charge value for the battery percentage, rather than the "smoothing algorithm" the battery driver uses, which I have discovered is flawed. See the README.md file in the linked folder for the patch and how to apply it, it's literally just a one character patch. Today I've added another patch to fix the suspend issue, so that automatic suspend now works again. I have been testing this and it's made a huge difference in battery life, making the PPP a daily drive-able phone for me! The battery issues were the only thing stopping me from switching from my Android to the PPP.
