Battery thief framed by app: all details inside

Following up from a battery draining problem, I've found a tool (BetterBatteryStats) that profiles battery usage in grater detail than the Android stock battery tool:

Here is the profile of a full day plagued by anomalous battery consumption:

BetterBatteryStats has found RILJ to be the prime suspect:

It seems to be a known behavior as said here:

I've followed the instruction and disabled Google geolocalization:

After some time running, RILJ is still top in battery usage, but it's weight is comparable to other processes, and battery consumption is a reasonable 1%/h

All went fine for some days, when after sending an SMS and receiving a call, the issue surfaced again.

I tried disabling "increase volume when in pocket".

My phone is running fine since then.
