Adding a high quality smart switch to a 5-year old battery might do some good, of course. But this is a cluster of old batteries, all in bad shape for many years of usage under different circumstances, temperatures, etc. And they’re all different models. Each battery will need a different time for going from 20 to 80%… it’s wild.

I do this kind of risk assessment on the worst scenario, a fire could turn your home into ashes. The only option to me, being strict, would be removing those batteries (after all, your main goal is to re-use the other hardware.) But that’s only possible in a handful of phone models… it’s just unfortunate. I guess I should get a FairPhone next time!

This doesn’t address the fire hazard at all.

I havent read the paper and surely he did a great job. Regardless of that, and in principle, anyone can do this in less than hour. The trick is to get an external confirmstion for all the discoveries you’ve made.

Corn has been doing that. We only need to wait for the oil lobby to die and then science will probably figure things out…

That’s probably the pricing before including anything (cpu, ram, ssd, ports.)

The more reason to get a Steam Deck.
