Can the pinephone be powered without a battery? - stragulus - 02-12-2020
I'd like to be able to power a smartphone device without the battery installed. Is this possible with the pinephone? Assuming by default it won't work (no phone after the galaxy S2 ever supported this), can the presence of a battery be faked such that it will work without damaging the device?
In case you're curious why: Intended application is to have it continuously powered near the head end of my bed where I will mainly use this device as a white noise generator and an alarm clock. I have currently gone through great trouble to rig up an LG Volt to do exactly this, but it relies on a questionable LineageOS build on the software end to work, and even more questionable methods to install said OS onto the phone. All in all it's a pain, and an open platform phone would be far more preferable.

Yes, see the wiki. Without any tweaks you are OK but have no modem, wifi or BT.

Promising! So in order to get everything working, one has to provide 3.8V through the battery terminals with enough current?

Why not just leave the battery in and have it continuously charging?

I hope the charge control strategy's better than that or our battery capacity will degrade faster than necessary, but I agree with the principle. The battery gives you a built in UPS n case of a power cut or glitch.

I had to try and see if it would work. As mentioned above, WiFi isn't working.

Batteries degrade faster if you do that, but more importantly it's right next to my head at night and I'd rather not have a high-energy prone-to-failure device so close to me.
