well ACKSHUALLY 🤓☝️

Unfortunately Pettyl is stupid enough to need the battery to boot, but smart enough to forget about it immediately afterwards.

I don’t make the rules, I just host WordPress on an 8-year-old Motorola.

Since their burst power consumption started using more current than a capacitor in the charging circuitry could provide

It's something about how the charging circuitry is constructed. I've asked a handful of electrical engineers about it but they've never given me a good answer. My guess is that it's easier/cheaper to design and build a circuit that only powers the phone off the battery, and only uses DC to charge the battery.

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)

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).

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 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.

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. 😂

This is obviously ridiculous.

So I’ll do it.

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.

Usually phones have 3 pins on the back for the battery, one of them - usually the one at the center - reads the battery resistance, so if you add a resistor between that pin and another pin, it will fool the phone to belive it has a beattery

Edit: spelling

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…

Nah, an actual UPS with 7kg batteries is way cooler.

But I really appreciate the feedback!

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!
