Again great news for the power issue on H300!
From the IRC logs:
[03:46] <amiconn> w0000000000000000000 0t !!!!
[03:47] * amiconn has contact to the isp1362
[03:47] <midkay> amiconn, great, congrats.

[03:47] <amiconn> Now we can try to send it to sleep...
[03:48] <amiconn> ...but before doing so, I need sleep :/
[03:48] <amiconn> We need to stop it from sucking battery
[03:49] <amiconn> midkay: USB on the go
[03:49] <amiconn> The problem was indeed a really fundamental one
<amiconn> We do want to support usbotg one day, but if the chip is not in use, it should be put to sleep
[03:54] <amiconn> The chip sucks power in the same order of magnitude as the CPU, thereby almost halving battery runtime on H300
[03:55] <midkay> amiconn, right, should certainly be disabled while it's not in use..
[03:55] <amiconn> I'd expect >19hours, but get 11 hours
[03:55] <amiconn> (stock battery)
That's all for now, hopefully it will be fixed soon....
