High Battery use after one time use, but on some phones only

[GoogleCodeExporter]

I use CSipSimple on several devices, and always with the exact same 
configuration.
Some details: Version 1.02.03, Integrate with Android, Only for outgoing, UDP 
only, Only "Wifi for outgoing calls" is checked under Network (and the 2 
"detect roaming" boxes, they were checked by default), nothing else.

I have the following observation:
- On all devices, after a fresh boot, and no CSipSimple call placed, power 
consumption is, say, 5% overnight (phone left alone untouched).
- On an htc Desire X (Stock Android 4.1.1), this does not change, even after I 
placed a call with CSipSimple in the evening
- But on a Samsung S4 Mini (Stock Android 4.4.2) the following happens 
reproducibly: After placing a short call with CSipSimple and hanging up again, 
the battery consumption of the phone rises to about 5% per HOUR (phone again in 
left alone in sleep mode and not touched overnight.)

This is despite the fact that CSIP simple is not shown by Samsung's task 
manager, and has apparently exited cleanly (also no icon shown in the task 
bar). Under Settings/Battery, the excessive battery consumption is assigned to 
"Android OS", CSipSimple does not even show on the list of apps using power 
there.

All settings not detailed above are left on the app's default, e.g. I did _not_ 
activate "Keep awake while on call", or "Activate partial wake lock", etc.

So it looks we have to somehow check what CSipSimple does here (on some phones 
only) ...

I have produced 3 screenshots illustrating the issue to more detail:

Screenshot 1 clearly demonstrates when the SIP call was taken, and how it 
permanently increased the power consumption of the (otherwise idle) phone. The 
screenshot also demonstrates that (before and after) the phone status really 
seems idle, specifically "WiFi" and "Awake" status are reported as essentially 
"off" (blue bars in the lower half of the screen). Only mobile network signal 
was "on" all the time (but I cut off "Mobile data", and it is barred from being 
used in my CSipSimple's network settings anyway).

Screenshot 2 seems to indicate that the bulk of the power consumption is 
attributed to "Android OS".

Screenshot 3 shows the power consumption details of "Android OS". Curiously, 
here a very long time of "Stay awake" is reported, this indicates where the 
power may be drawn to, (at least as far this Android Power consumption setting 
interprets it).

I have so far not found any other way to rectify the situation than a complete 
device re-start. (Also going to Samsung's "Active Apps" manager and clearing 
the RAM there, which seems to close all background apps, did not change this 
behavior).

Unfortunately I cannot attach the screenshots here due to "quota exceeded", so 
I will send them to the project owner by mail, hope that's ok.

Just as a workaround for the mean time while this is not resolved: The only 2 
ways I could find so far to stop the excessive battery drain again after a SIP 
call are
- either completely re-boot your device
- or go to Android's settings, App manager, and force-stop CSipSimple. You can 
immediately re-start CSipSimple by tapping it in your devices apps folder to 
re-create the Android device integration with the dialer for the next time you 
dial  (then exit CSipSimple again).
