I just wanted to post some interesting discoveries on battery drain and baseband settings.
Some infos: I'm currently running the most recent quarx CM10 4.1.2 version (20121109) with full gapps, the default CPU governor (interactive) and the default VSels and CPU-Speed, I also installed
the battd-fix some days ago. I live in Germany and use the O2 mobile network, so these particular settings probably
only apply to central European users!
Cause I had issues with mobile connectivity I tried different baseband versions in the last weeks and ended up with 2.21 because this one seemed to be reliable and stable. After some days, again I had problems so I switched baseband back to 3.4.x yesterday.
Good news: I didn't have any problems today and after 8h12min uptime I am still on 87% battery! That was
a lot worse before. Well, I didn't use my phone that much today (some messaging, maybe 30 minutes of music with Apollo, Wifi most of the time on) but I guess this is freaking incredible, compared to before.
TL;DR : If anyone has problems with battery life, try changing your baseband settings!
