okay well holding back the switch 15s just literally causes a reboot by cutting the power AFAIK so that sounds right.

Knc1 now knows the most of anyone about the charging logic I would say given his extensive research.

EDIT: Ah *looks up* yeah. him.

I'm firing up my 3 gimme sec...
see if I can grab out some metrics

possible reports:

Quote:
gasgauge-info [-cdhklms] [-i <seconds>] <registers...>
-c output state of charge in percent
-d dump all gas gauge registers
-h help
-i s interval (seconds)
-s same as -c
-t add a timestamp to dumps
-v output battery voltage value
-l output battery charge current (load)
-k output battery temperature
-m output battery available capacity (mAh)
ON A WALL CHARGER:

Hope that is helpful. let me know if not. and I'll run the tests again.

Cheers.

I don't have a battery that is less than 99% full. I will run it down a bit and repeat. (leaves it running an audio book on mute...)

[root@kindle root]# gasgauge-info -c
99%
Thu Oct 11 14:04:40 2012 *INFO:battery charge: 99%

[root@kindle root]# gasgauge-info -k
68 Fahrenheit
Thu Oct 11 14:00:30 2012 INFO:battery temperature: 68 Fahrenheit
(that's 20C to we that need the conversion)
and about 11 above the ambient room temperature
