Also, does Jitsi for Android work for XMPP/Jingle video/audio calls?
Charged and rebooted the phone last evening. After some two hours from that I switched WLAN on and XMPP online. 3gdata was still on and idling.

The server is OpenFire.

XMPP with WLAN. In 10 hours idle use battery dropped from 93% to 62%. This gives 3 percent drop per hour.

I switched to 3gdata battery at 39%. From that on after next six hours the battery showed 20%. This gives approximately same figure as on WLAN, eg. ~3% per hour, if the battery statistics are correct.

I think it is quite safe to say that plain XMPP in good radio conditions does not use too much power.

I tried Jitsi Android build 163 (maybe a month old nightly), and while I was able to call people inside the same network, when they answered the client simply hung up the call. I recall that this same thing happened earlier with Nexus 7 with the same version of Jitsi. So I'll have to test it later again with the latest build and both devices...
