1. remove phone silencer from apps, it causes these "stupid" question. I find it very useful.
You disconnected the phone more than 2 hours before. Being awake is not equivalent to having the display on. Frequently the phone wakes when the screen is off because of some services. You can see it on the graph in battery stats. You can also use Betterbatterystats to check wakelocks showing you processes that awoke the phone.
Thats why is asked how to remove.
I know that it could happend that the phones wakes up, also when the screen is off. But 7 min in 2 hours? So i want to know what this rom is doing when the screen is off.
