• It certainly shows the potential for mobile Linux for sure. There’s a project https://postmarketos.org where you can install their mobile Linux OS on Android phones if you want to give it a try on a spare phone or something. The wiki lists what phones the OS can be installed on and what hardware features are working for each device.

        • When the phone is not set to suspend, and mostly idle with a couple of apps running, and some occasional web browsing, its about 4 hours. Under similar conditions using suspend (meaning it will keep the modem powered and wake up the rest of the device wen receiving phone calls and SMS) then I can get through a 9 hour workday and have about 40% battery left.

          I have been daily driving the phone for a couple of years so I’m sure the battery has degraded some, but I don’t know how much difference I would get with a new one. It can be easily replaced, so I may do that in the future.
