I meant battery drains fast, no deep sleep. I hope now you understand.

I think he meant faster battery drain due to wakelock and network issue which you said will be fixed in this build.
Aug 17, 2012
I understand. I don't think this is fixed now in v0.2.0. It will come in a next release.

Attaching screenshots of Better Battery Stats and Battery Graph so that you can understand it better. As you can see phone is always awake and not going to sleep. Not fixed in v0.2.0 as you said.

I'm satisfied with the battery backup for now considering it really a early build with CM9 Kernel. Hope Oxygen kernel improves it with WiFi and Data too :) Here are few screenshots to help you decide whether it's good or not.

The problem with the battery still exists at the version 0.4.0 (ICS). The battery drains very fast. Except from this problem the phone is working faster.

Granted, there still are bugs in the ICS rom that wake up the phone and drain the battery. But Android 4+ is a battery hog. I've managed to make the phone sleep more and so you can get 3-4 days of standby. But once the phone wakes up, it drains the battery like crazy. There is not much I can do about that. The added features require more juice. That's why with every Android update, the battery life has decreased Froyo>GB>ICS>JB and so on.

I feel the same way. With the ICS version, battery drains many times faster than the GB version. Using the GB version I was able to have the phone working for a whole week (2G network and not using the phone). Now in airplane mode and the Processor in 99% deep sleep at all time, it lasts a day at best. I think I will go back to GB while this battery issue isn't fixed. It's a shame, I liked ICS A LOT. Although it's a little bit slower than GB too. Ps:. Sorry I deleted my comment after you posted a reply. Great to see that developers answer so fast. And yeah, the newer versions seem to require more and more power. A shame, since ICS has a lot of good features.
