The device gets in deep suspend mode only when wifi is not actively used. When you're pinging or actively using the phone via SSH, the driver will hold a wakelock and block suspend. You can check for how long the device was actually suspended by checking your /var/log/syslog. Check bug https://bugs.launchpad.net/ubuntu/+source/powerd/+bug/1372413 as well (like comment #3), as there is already a tool that can parse your syslog give you the info you need. > How can I read, i.e. from which file, the actual power values, like > charging rate, power consumption in V and mA?

Upower exports the battery percentage and voltage via DBUS (signals), so that is one way. phablet@ubuntu-phablet:~$ upower -d Device: /org/freedesktop/UPower/devices/battery_battery native-path: battery power supply: yes updated: Tue 07 Apr 2015 01:06:49 AM BRT (7 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 0 Wh energy-empty: 0 Wh energy-full: 0 Wh energy-full-design: 0 Wh energy-rate: 0 W voltage: 4.221 V percentage: 92% temperature: 25 degrees C capacity: 100% technology: lithium-ion icon-name: 'battery-full-charging-symbolic' History (charge): 1428379539 92.000 charging Another way is going directly at /sys/devices/platform/battery/power_supply/battery/ and checking the files 'capacity' and 'voltage_now'.
