Yeah, I need it to at least keep wifi on and receive push notifications.

I’ve yet to drive down a battery to 25% capacity, but I recall seeing drain on linux phones being like 4x what aosp gets.
And for batteries I have hope of phone repairs.

And then add to that, that more drain means more charge cycles means faster degradation too.

The working features should allow to use the device in most common use cases. A phone for example would typically have calls, SMS, mobile data, Wi-Fi, audio, battery charging, Bluetooth and camera.

What’s the battery life like these days?
That seems like it’d be one of my main blockers, if it can’t last a day with low use.
