Low Power Consumption Phone

[biketool]

I've been thinking lately one of the issues with the PinePhone concept is that people are working very hard to just replicate what you already can get through Android or IOS. In a way it's almost just a novelty.

Quite frankly, this is a somewhat wrong way of thinking.  Please allow me to explain.(snip)

I need what pinephone is at hardware and with daily driver grade software setup will eventually be, a full function pocket computer phone with an easy to use and hack UI with trusted hardware and software.
That siad....
I would like even more a pocket sized computer which for most purposes can run on a very low consumption ARM or RISC V CPU optomized low power programs(look what we could do in 1999 on an old 200mhz ARM Linux Zaurus) and light up a higher performing watt waster CPU when needed, maybe displaying a warning, say a red border or whatever, so a user doesn't accidently burn through a battery in a few hours when they need a week or more of lifetime for a situation.

I also am called to work in an environments where water resist, a long life low temp battery, option of solar charging, and a e-ink/e-paper display, the solar/e-ink can both be in a case cover. 
Give me an over the top dream gadget, slider keyboard with NFC and Qi as well as some i2c pads and maybe a USB or two for stuff like RTL-SDR, then a flap cover for the front of the phone to portect the glass, inside an eInk and outside a charging solar cell; if you can somehow shoehorn a real SDR with amplified to usable TX for amateur radio freqs even better.  I used to carry a bagphone in the 90s, I still carry around two HTs in my bag as well as often a QRP radio.  I am sure there will be others like me.
