Unofficial Pinephone Battery Case
Picked up an S20 Ultra battery case with 8,500 mAh battery. I've left my Pinephone Pro off the charger for two days straight without charging and it's still at 100% with battery case showing only 50% capacity. Combined the Pinephone Pro's battery 3,000 mAh battery with the extended battery case 8,500 mAh battery gives the Pinephone Pro a whopping 11,500 mAh charge to work with. I've used about 3 hours screen on time both days (6 hours screen time total) without seeing much drain at all, and this is with suspend completely disabled.

While the official Keyboard case does offer a similar solution with a 6,000 mAh battery, I decided having a keyboard in my face in public is not ideal.

The buttons line up perfectly with the case buttons, but has a half inch gap at the top between case and phone. Also be aware the thickness of the phone is doubled to almost the size of the keyboard case and does add a little extra weight but feels durable.

The case, however, offers no protection if your phone would to fall screen face down, so be aware of this as well.

I've had the charging case for 48h on Manjaro so reliability and lifespan of the case still hasn't been assessed, but for $25 I feel it's pretty low risk. The case takes about 6-8 hours to charge from zero but this fine for an overnight charge while sleeping --did this as soon as I got it. You do not need to take the phone out to charge case.

The Pinephone Pro in this case seems to only reliably work in Manjaro at the moment as Arch power management is still early and drains faster than the case can charge it, but this is a bug which should be worked out soon. Have not tried with Postmarket or Mobian. I've also not tested peripherals such as OTG cables / hubs in the USB C port but will report back once I've done so.

The battery can be toggled with the power button on the back and Manjaro will report immediately when charge is active. Turn it off if you wish to power the phone down as the constant charge causes the phone to boot again

Here is a link to the case if anyone is interested:

Feel free to ask any questions I didn't address here and I'll do my best to answer them.
