Part 3: They said a phone can’t run without a battery. Unfortunately, Pettyl didn’t get the memo. (lemmy.zip)

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.

nginx: UP PHP-FPM: UP MariaDB: UP WordPress: UP cloudflared: UP sshd: UP

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:

  1. Insert battery
  2. Boot Pettyl
  3. Connect USB power
  4. Remove battery
  5. 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.

I did not need to fake battery presence, just needed the battery as a starter, once the phone is booted just removed the battery.

Although the real test is yet to come, I have to leave it like this for a day or two, to see if it powers off when CPU spikes…

Awww... I remember back when batteries were removable. Good times.
