There are a lot of people out there who have troubles with the new ICS 4.0.3 update for the Google Nexus S because it's draining the battery and has high CPU load.

Google has stoped the rollout of the update for the moment.

The Galaxy Nexus seems to have a similar problem...

I have made a video that demonstrates a strange effect: The display auto rotation setting seems to have a huge impact on CPU load:

Good find! I am going to test it myself. Thanks!
 
I have no idea, why this setting has an influence on cpu load...
 
Well, me neither, but it seems that you are right: disabling display auto rotation keeps Android OS CPU consumption much lower!
Tested on my Nexus S too.
 
We've testet it on a Galaxy Nexus with 4.0.1: same issue...
 
Good! Im going to turn off the auto rotation for now to have a test, btw I installed a shake and rotate app , maybe thats a reason too.
 
Also, Disabling the Google+ App seems to help with battery life as well. Hopefully we get a Nexus S ICS official update soon...
 
Thanks. I always had auto rotation off on my N1 as it seemed pretty sensitive but the GN seems to handle it better so have kept it on. Will turn it off to see the impact on battery.
 
To clarify: I personaly don't think this auto rotation thing is the main reason for the cpu/battery issue, it's only a side effect... The real problem lies elsewhere.
 
Zom glügg probierets da zersch bi eu us und chunt usgriift uf mis H*C ;)
