Great info, thank you Robert !<br>

I suppose you can confirm that C6* time and usage doesn't change after<br>
starting the script. C7* are not used that much, but that's probably<br>
because you got this snapshot shortly after boot/tests.<br>

Wow... That's a lot of parameters... I'll check mine when I can.<br>
<br>
What about battery life or device temperature when you leave it alone<br>
(it's a bit warm when I leave it alone without C7*) ?<br>
