PinePhone sensors - Gyroscope power - WhiteHexagon - 11-27-2025
So I got the proximity / light sensor working in my Zig OS
Although the sensor seems to be always powered on, which kinda makes sense, but I somehow expected a GPIO pin for switching it off. Now I am looking at the gyroscope, wow it looks complicated
and I am kinda glad to see the secondary I2C fusion? lines are not connected.But here again it seems to be always powered on? (based on schematic), and I recall from my early iOS days, that gyroscopes can waste some power when always on. Did I miss something?

The PinePhone hardware is not optimized for power consumption at all. I guess the gyroscope is the least of your worries there.

Thanks for the honest answer! I'm hoping at some point I'll be able to use the RSB bus to monitor power usage, if that is supported? Are there any power hungry parts I should be watching out for please?
I did manage to get the idle temperature down to 42C, so I hope that will reflect in less power usage
Although I think I'll need a 2nd core fired up soon, if I can work out how. Whatever else people say about the PinePhone, I think it is a great learning tool for systems programming!
