This post is an update of the second part of my Moto server series: https://lemmy.zip/post/72142441
Rumor has it that keeping an 8-year-old phone permanently plugged in with its equally ancient Li-ion battery might not be the greatest idea ever conceived.
Some even claimed that a phone needs a battery to work.
Very negative people.
Anyway, I removed it.
Pettyl did not care.

The battery is currently sitting next to the phone, contributing absolutely nothing to the project.
Pettyl is now running entirely from USB power, at around 37°C, while continuing to serve the website like this is completely normal.
There is, however, one tiny detail the haters may enjoy:
It can’t boot without the battery.
So the official Pettyl disaster recovery procedure is now:
- Insert battery
- Boot Pettyl
- Connect USB power
- Remove battery
- Pretend this is enterprise infrastructure
The battery is no longer a battery.
It is the starter motor.
I see no problems with this architecture.
Anyway, Part 3 is going great.
Nice.
There is often a check for battery that is effectively a check of resistance between sense and ground. Looks like that battery is labelled, you might be able to bodge a resistor between sense and ground on the phone and get it to boot without the battery?
Here I was thinking you should add a capacitor so there is some juice if the phone draws more than the USB can supply. Maybe even a super cap so you get a more robust drain discharge cycles.
