HP Prime Battery consumption analysis

[StephenG1CMZ]

When I heard that the HP Prime needed such batteries because of the colour screen and faster processor I did consider the 50g.

I wonder whether the Prime could switch to AA batteries if the faster processor were retained and the screen omitted.

Of course, some of the power saved by omitting the screen would be required to send the display to a mobile phone.

HP have of course chosen a different solution: emulating the whole calculator as an app, rather than just using the mobile as a screen display.

But would omitting the screen have been a sufficient power saving to use AA batteries?
