Hello guys.

I got mine 3.6Ah battery before a week and I have some observations about its behaviuor. First - N810 reports 10 days for the battery fully charged. 10 days I read as 100% full.

Only once N810 said 16 day when I first placed the new battery. After one charge cycle it consistently says 10 .. 0 days while discharging.

I tested run time. And I am not quite satisfied. Emailed to eten.hu and waiting response.

I tested run time putting N810 at 100% cpu load by little shell script:
while :; do seq 1 40000000; done

The original battery runs about 6h45m.
The new one runs about 10h.
Tested twice.

Times are for discharging full battery until N810 powers off.
10h run time in this case suggests battery of 2.2Ah. Not 3.6

This may be caused by not enough charging or not fully discharging battery also.
Waiting response from eten.hu.
