Sorry i did not know this was a contest. When i use the phone only for one day and reduce the brightness i'm sure SOT would have been 7-8 hours, but this is not the way i use my phone.
I think it matters. When i go abroad, i want to see what provider has been choosen.
I really love the battery lifetime. That is the first time where i can say, that this is good for Android.
(screentime 90 minutes)
Update on my device:
Regarding mute calls - i think the HTC One has the same, and Trip solved it, see http://forum.xda-developers.com/showthread.php?p=43888422#post43888422
Maybe this helps? Dunno if this is really the same issue.
