Megous posted a follow-up: Some ways to improve Pinephone safety -- https://xnux.eu/log/#018
Alright, something can be gotten to work to protect the PinePhone from going up in flames. I know it will be pretty crude, due to granularity of 3kOhm vs 10kOhm NTC and the tolerance of the part (5% on NTC fitted to Pine64 battery vs 1%). It's better than nothing which is present situation.
Optimisations to eke out power usage safely are a compromise but can be worked on. It will possibly work out eventually for PinePhone outside of a convergence situation. However for convergence, there are still the concerns that Megous has mentioned in earlier (b)log with power consumption being over safe limit. Grateful to Megous for providing all those pointers on what needs doing thanks!
IMO it still may need a re-think about the battery and replacing it with a beefed up one with more granularity on TS. Mostly, in order to make convergence work safely.
May be it might also take a community edition of the PinePhone specifically to help fund safety.
Big question is who is going to take this on?
Yes, another Linux phone offering convergence.
Of course, for the price you'd expect them to be on top of all the nitty-gritty details like thermal management and power developing the software themselves. The battery is 3,500mAh (probably 3,700-3,800mAh) so a better chance theirs will operate more safely during convergence. Plus, the notification LED has PWM which is desirable to me.
The downside of the Purism phone is also the software i.e. you might be stuck with what they offer.
Integrating or running other software distros might offer something minus whatever Purism added to manage safety.
So I prefer instead to buy a $200-or-less phone with diversity of software and carry on using a laptop.

I suggest to everyone concerned about these safety issues to consider Librem 5: https://forums.puri.sm/t/comparing-specs...hones/6827 (I personally preordered both phones).
