as 2 or 3 hours before, but at some 15%.
That's something I noticed too and I'm not sure how we could make it
better. I've frequently used my Keon as a wifi hotspot so that both my
laptop and my wife's could get internet access via my data plan when
traveling. Under those conditions the only way to keep the battery
from drying up is to have it charging via USB at the same time.
In spite of this, under active usage the phone almost doesn't charge
so it's apparent that keeping both the 3G and WiFi antennas busy (plus
the AES encryption on the traffic) is not easy on the hardware.

I know that some home wifi hot spots do some kind of sleep polling thing
to save energy. It means to passively poll for incoming ethernet
requests after some time of inactivitiy every few hundred or (even more)
milliseconds. This could save battery potentially for at least my
case. I understand that when actively using the phone as a hot spot the
battery will go fast down, but for occasional usage it could work.
Patrick might now more as he discovered that 'feature' of home hot spots
recently.
