So the Fairphone 2 runs on just a USB cable with no battery inside?
Yup that's right!

I've gone through a dozen or so LiPo-utilizing portable devices at my property in the Mojave desert. All it takes is a single season for many of these batteries to swell up to such an extent the enclosures split open. Ostensibly they contain charge controllers and temperature sensors, yet they're unable to prevent this outcome when the ambient temperature exceeds 110F day after day while the device stays on in a hot…
This has nothing to do with being near full charge and everything to do with the temperature.
Leaving such devices plugged in 24x7 unattended creates opportunities for such ambient conditions to develop unnoticed.
These mobile LiPo-using rechargeable devices simply aren't ideal for being left powered while unattended, day after day, year after year. All it takes are some sunny days with normally closed blinds left open and you may slowly be cooking that device you forgot about that Just Works but is a ticking time bomb after the 10th day it spent an hour in direct sunlight while charging.
AIUI the high temperatures are particularly damaging to the SEI (Solid Electrolyte Interface) layer, which is the layer preventing dendrite growth. If that layer breaks down enough for dendrites to grow, you're in internal short / fire-risk land.

For home automation, how much energy my solar system produces, birthdays, weather forecast. Stuff like that.
did you flash it or do you just use the browser?
I flashed it. Don’t know if always on works with the browser. But jailbreaking is easy and I think even reversible. Then you can ssh into it and even setup a cron to download a picture and refresh the screen.
