i am using the latest version of CM6 on my Motorola Milestone. The one based on the G.O.T. sbf with the 2.2 test kernel.
I was experiencing a significant battery drain. The battery wouldn’t hold a whole day…
So i did a little analysis.
First i found a little hidden feature of Android. Go to the phone app and type: *#*#4636#*#*. This will bringt up some stats. Most interesting are the battery usage stats.
Here is saw that “Being executed” (“Wird ausgeführt” in german) had 100%. That means that the Milestone didn’t go to deep sleep at all. So i tried to find out why. There is another stats screen titled “usage in partial sleep mode” or something like that (“Verwendung im Teilwachzustand” in german). There i saw “Facebook” with nearly 70% of all apps that were listed there.
So i went to the facebook app and deactivated the notifications (which didn’t work for me anyway). And the problem was fixed. The Milestone is now going into deep sleep normally and the battery drain is gone
Hope that helps many of you out there suffering under the battery drain!
