> I have a fair bit of experience with charging batteries of many types, and with confidence I can say that these concerns are largely overblown. Any appropriately designed battery charging system will stop charging the battery once it's fully charged.
Tell that to the multitude of laptops I've owned and/or repaired because the battery swells up and pushes the keyboard and trackpad out of the chassis.
I had a little fleet of phones doing some IoT-like operation but they eventually all went offline, restarted, or just developed wonky issues.
Cell phones simply do not like being powered on 24/7 and actively doing things - they are used to being used for a bit, then off. It gets worse as the battery ages, of course - and maybe that's the main reason for the failures.
Oh my god please tell me someone remembered to throw the toilet-water-rice out and not accidentally use it for cooking X-(
If only we had truly unlimited data plans to go with it
I did. Several old devices of mine died like that.
At higher voltages the passivation layer at the cathode, necessary for the battery to function, becomes unstable and decomposes.

> Researchers at the University of California San Diego are planning a 2,000-phone computing cluster to support computer science classes such as Parallel Computation and Systems Programming. Early experiments show that even a moderately-sized cluster of 20 phones is capable of supporting peak submission rates for a 75+ student class, with grading latencies below the default AWS backend. A 2,000 phone deployment will be capable of supporting a hundred such classes at once.

I do think there is huge potential here for things like running lots of semi persistent agent harnesses. The work time is currently massively dominated by the remote LLMs, so running on old phones would be cheap and because of Amdahl's Law it wouldnt really be much slower.
