EOS 2.0 ICS deep sleep issue

[Bux1982]

Ok, so I´d like to post this directly to the development forum but I´m not allowed to due to my post count.

Anyway, reading through the related threads, I know I´m not the only one with the following issue.

I used the EOS 1.0 stable on my MZ601 (European/German) since it came out and it was pretty awesome. Battery life was good, and after I wiped cache and dalvik cache once, deep sleep worked like a charme.
Uptime with light usage was between 4 and 5 days

About 3 weeks ago, I upgraded to EOS 2.0 stable and my battery life is a nightmare.
Xoom eats away a full charge in about 1.5 days of just laying around.
I did not use it on purpose to check how long it will take.
Sure I wiped cache and dalvik like before, but nothing helps.


CPU Spy tells me this...
the Tab is not brought back from deep sleep by some app or system call.
The Xoom doesn´t even goes into deep sleep, not at all.
It runs on 266mHz all the time, and AndroidOS consumes allmost 90% of the battery.


Any advice about what to do next?
Even given the fact that 2.0 is a fantastic release and I don´t want to, I consider going back to 1.0 at the moment.

On mine it seems to relate to specific apps. If I reboot, and run nothing, then it does go to deep sleep. If I use a few apps, then it does deep sleep some, but not as it used to.
I have not figured out which apps, or why the change with the upgrade. But one of the apps that seems to greatly reduce deep sleep is email (with exchange). Even though I have it set to never check my mail(except manually) it seems to have wake up alarms that reduce deep sleep and battery like a bunch. If I run mail after a reboot.

Use EOS latest nightly (build74).
In older builds (before 74) I also had this issue.
Now all is fine.
