</div>Hm, there's probably something very wrong with your config, no?<br>
<br>
With GSM on in suspend it should last for 140 hrs and with off it<br>
should be even more.</blockquote><div><br>Really? Isn't that with deep sleep on?<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Hm, so basically your point is that CC allows current measurement in<br>
suspend. Ok, but if there're convenient TPs you can use your DMM to do<br>
the same as well. Also you can do that by connecting the device via<br>
DMM to a lab PSU or a pack of AA batteries. Moreover, there's quite a<br>
limited number of usecases (wrt power-management) so those who has<br>
some EE skills can do the measurements once and then share the info<br>
for everybody.<br>
