Comment(by lala):
And another thing, maybe will be helpful: the power consumption is ~100mA
with brightness set to low and gsm activated. When events/0 starts to eat
~27% CPU, the consumption goes to 200-240mA, and after 2-3 hours the front
of the neo is unusual hot.

Comment(by andy):
Wow that is good to know, folks have reported that hotness symptom before,
at least we got a clue now it is associated with the events thing and
seems to be to do with WLAN.
When WLAN is in RX or TX in RF, it can pull these kinds of currents like
extra 400mW. Normally it uses 80211 powersave and times its RF activity
around the beacon of the AP, so its average power is much lower. But if
for some reason its RF stage was stuck on, it will heat up itself and
maybe also raise the temperature of the battery.

It's an interesting clue... I guess it means that the settings in the
display asic can be lost during suspend.
