6 hours 7 minutes of idle time with modem on and fully reachable on Birch! That'd be about 10h for Dogwood's battery!
The only caveat: SD card reader needs to be disabled (for now). Power management comes together pretty nicely on the Librem 5! :)
With modem and WiFi on I got 5h 34min, and with both off - 7h 45min. With final battery that should translate to about 9h and 12h respectively.
This progress comes mostly due to runtime power management improvements - we don't suspend the CPU! With WiFi on, the phone was reachable and ssh-able through all this time.
@dos out of curiosity, would a suspended cpu be able to process incoming calls and potentially increase battery life even more? Or is it a deliberate decision to keep it powered on when the screen is off?
Amazing to see how much battery life is improving!
@Alexmitter @agx @dos It would sound like push messages could send some sort of interrupt, to temporarily wake up the cpu?
@Alexmitter @agx @dos right :) to be honest I trust the purism developers 100% in choosing the right way to handle this. I can't wait to get the thing, but it's still great to see how it keeps improving the way it does.
@agx @vancha @dos Would it be possible that the cpu wakes up every few minutes for a short moment to check for push notification updates?
