Hello,

To catch the reason for battery drain I have a cron job which puts every
5 minutes (when the system is awaked from suspend) the information about
the battery and the top 20 CPU processes, like this block into a log
file:

Mon Jul 13 08:45:01 CEST 2015

What calls my attention was the proc 2396 with high CPU utilization:

phablet@ubuntu-phablet:~$ ps ax | fgrep scope
 2319 ?        Ssl    0:06 /usr/lib/arm-linux-gnueabihf/unity-scopes/smartscopesproxy upstart
 2396 ?        Ssl  240:49 /usr/lib/arm-linux-gnueabihf/unity-scopes/scoperegistry

which runs since yesterday like this:

Sun Jul 12 12:30:06 CEST 2015
 2396 phablet   20   0  369716   3456   2360 S  54.4  0.4   1:43.38 scoperegis+

What is this?
