 I've checked the power consumtion as PaulFertser told me using that
 script:
 while true; do cat /sys/class/power_supply/battery/current_now
 >>/var/log/power.log; sleep 1; done
 and suspended/resumed several times, then checked logs.
 The results were horrible:
 52125
 45375
 41437
 Seems that there's something completely wrong with power consumption
 while suspended.
 The Neo lives on battery while suspended only for 1 day in best not
 resumed.
 I'm using shr-unstable
