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

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.

Hahaha, thank you for defending me! 😄

Just to clarify though, the “they said it couldn’t be done” part was mostly me being ironic and unnecessarily dramatic for the post lol. The comments on this whole project have actually been overwhelmingly positive and helpful.

People here are the reason I even tried some of this stuff in the first place.

But I genuinely appreciate you having my back. And the S5 being able to cold boot without a battery is really interesting — Pettyl unfortunately needs its battery as a starter motor. 😂
