I was following your concerns and totally understanding the desire for a larger battery, this is totally not necessary. Anyone can easily use any size battery you throw at them, just like storage or ram or cpu speed, and that's what I'm seeing from this. For example, why would you ever need to run a linux vm? Why would you not run your linux instance on a machine somewhere in your virtual private network that you're connected to 24/7? Why do you need to be waking up the phone to run tasker processes so often?
I'd totally be in favour of a larger battery, but I think you could be happy with
