Would love to make this device primary.
Any feedback on the problems / proposed solutions greatly appreciated.
Drove original PinePhone on postmarketOS SXMO + WayDroid for a while. PPP is amazing here, but strangely, suspend doesn't seem to work.
The device will discharge (to 0% battery) if not charged over night, and last ~2 hours without a charger. Random poweroffs.
All connectivity is kill-switched. dmesg reports - "PM: Some devices failed to suspend, or early wake event detected".
Read somewhere that PPP should last for 24h minimally if suspended, yet it doesn't seem to work regardless of OS.
Wireless charging case sadly isn't sold any more (to pair with a smartphone charging case).
Before velcro-fastening the most compact 20000mAh powerbank on a back of PPP, trying software fixes might be in order.
postmarketOS doesn't seem to use Megi's now legendary kernel though, due to it not being mainlined, missing on PPP-critical patches.
Megi's https://xff.cz/kernels/ offers pre-built ones, but sadly kinda lost on how to make it work on postmarketOS (based on Alpine).
Arch seems to use Megi's kernel or patches, but it didn't survive the night either.
Mobian seemed ok, but couldn't get the SXMO working.
The device is also pretty hot. Like, literally.
Convergence + heavier use might need better heat dissipation to prevent thermal throttling (think I read it starts at 65°C/149°F on PPP).
Thinking about using 0.05mm copper pads with kapton tape on conductive shielding to prevent short-circuits & improve cooling.
USB-C doesn't work for data transfers, camera neither, but that isn't deal-breaker.
Anyway, very thankful for the effort that has been put into this by some very talented individuals; making a real pocket privacy-respecting (air-gappable) device possible.
