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:
- 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.
I should test this with my old s8
Had to toss the spicy pillow and had no clue what to do with it since
Perhaps replace its aging battery with a new one. Then you have a built in UPS for ideal disaster recovery
Nah, an actual UPS with 7kg batteries is way cooler.
But I really appreciate the feedback!
Perhaps then some solar power as well. I think those ecoflow battery + solar can act as UPS too. Could power that server indefinitely 😂
Now we’re speaking the same language!
Can you get a second identical phone. Or a third? I’m thinking perhaps load balancing and failover
Maybe not an identical one, but I did find an interesting Note 9 for around $40…
I guess this is foreshadowing…
Definitely take the battery out of that one
Yeah, for 40 bucks I get a phone with good specs and a free pillow!
Glorious.
Well… I was obviously wrong. Sorry.
Don’t know if my knowledge was just outdated or plain wrong from the start, but good on you for still trying and respect for pulling that off.
You are absolutely fine!
People here, including you, have been very respectful and thoughtful, and I am all for feedback.
I don’t have the knowledge of the whole universe, do I? So please, by all means, I want to hear your critiques, it makes the project better and I learn along the way!
Now plug the phone into a UPS so if the power goes out you’re good for awhile.
This is obviously ridiculous.
So I’ll do it.
I’m honoured to have my idea contributed to this project!
When the battery in my wall mounted android tablet swelled i had to add a 10k resistor to the sense line, inject the 5V directly into the battery port and add a few capacitors to get it to work. But at least it won’t cause a fire now.
Well you better go catch it!
DO NOT skip step 5. It is VERY IMPORTANT.
Remember bezels?
I just have to say, I really enjoy your writing style. Fun project, great post!
Thank you for the kind words 🎩
Remember the days when hou could just pop the back off and take the battery out?
That’s where I am today with my Fairphone.
I honestly held on to my old Nokia, replacing batteries and cases until Fairphone came along and then I jumped from 90’s tech to modern day.
0–>100% in 10 seconds (with a 2nd battery)
And it would still run when you had it plugged in. I could remove the battery from my old Galaxy S2, plug it in and it would work. And if I remember correctly, the same thing went for most of the phones I had before that.
Still have my LG Optimus on Android 2.x somewhere. With 512MB RAM I dunno what to do with it outside of a clock display, but I have it (and a spare battery).
Anything made to be run from battery can work fine without one. Worst case scenario requires you to spoof some I²C communication to properly emulate a battery, but most devices and batteries are far dumber than that. DC is DC, and sometimes you just need to graft something on top for the other pins.
Source: My old laptops charging circuit failed, so I soldered the charger onto the battery pins instead. Then I replaced the actual battery with an Adafruit Itsybitsy 32u4 (because that what I happened to have available) that emulated the battery status of “Charging, nothing to see here, move along” and sent it via I²C
The charging cirtuit that also tries to guess the battery percentage can be the problem. The ‘guessed percentage’ will depending on the chip and programming go down even if you solder in a dc power supply. When it hits the 0% it will shutdown.
Thats the case for some smart phones.
How do I sign up for the pateron?
Damn, I wish they still made phones with a removable battery
All batteries are removable once
I just got a fairphone 6. Removable battery!
Didn’t EU pass a regulation regarding that? If I recall correctly all portable devices sold in the EU after February will will need to have a user replaceable battery.
i’m curious to see how apple will workaround the regulation
They already did I believe. They enhanced their battery glue so it should be easier to remove; reduced the amount of different screwdriver types required to access the battery to one or two; and put a small repair tool set up for sale, for the low price of $700. Thats already impressive for Apple standards
Didn’t know that, fantastic!
I used to keep a charged spare on me. And this was back when a phones battery life was like 3-7 days.
Stop making phones thinner God dammit. I don’t want a thinner phone. I want longer battery life and a removable battery so I can fucking double the shitty longer battery life I get.
I used to keep a charged spare on me.
There’s at least one Chinese brand that has smartphone with hot-swappable battery: https://rugone.net/products/xever-8
Removable battery. Swap within 2 minutes for zero interruption. After 2 minutes, the device enters a 60-second safety lock-out to protect your data.
Unfortunately, software from these brands tends to be shit. I feel like they just outsource it to the cheapest company. Especially following this recent thing:
As of March 4, Sophos X-Intercept telemetry listed over 500 unique compromised Android devices across nearly 50 models. The devices were mostly low-cost models produced by the following manufacturers: Allview, BLU, Dcode, DOOGEE, Gigaset, Gionee, Lava, and Ulefone. The list did not include Alldocube devices, despite Kaspersky reportedly observing Keenadu affect that manufacturer as well.
And a big enough pocket to hold it securely, no matter what gender clothing you wear!
Here here!
There, there. It’s “hear, hear.”
Where, where?
Wherever you were talking about when you said “here.”
Oh, there, there?

That’s kinda hard when women’s pants often have no pockets, fake pockets, or pockets so small they’re functionally useless.
That’s why it’s a response to “I want…”!
An add-on to the wishlist, as it were. I’m just an old non-tech cis woman but I firmly believe generous pockets could and should be designed/engineered/built into every twirly skirt, every thigh-high (but down near the ankle bc gravity) every booty pant and even red-carpet gala gowns. At least someone finally realized workout leggings can have a pocket down on the leg if it’s so god-damned important not to interrupt the “line” elsewhere.
And everyone should feel free to wear whatever styles they feel suit them, with neither social stigma nor pocket-neglectful construction holding them back.
Hell yeah sister! I’m 100% for this. I’m a cis guy but the clear disparity of pants pockets between gendered clothing (and clothing being gendered at all) has always irked me. Everyone should have equal access to pockets!! (Silly but serious)
