Google began rolling out the Nexus S ICS update in several regions a short time ago but it seems they’ve already had to suspend the upgrade for an issue that is affecting battery life.
Alongside abnormal battery drain users are seeing high spikes of CPU usage, two things that could be directly related. If you’ve gotten a notification that the upgrade was available but you have since been unable to apply it, don’t worry – you’re not crazy.
Now is as good a time as any to mention that Galaxy Nexus users have also been experiencing less-than-normal battery drainage for quite some time. Many believe it to be a kernel driver issue and is causing the OS to keep the device awake (this doesn’t necessarily mean the screen has to be on) which causes excessive battery drain.
I personally have been seeing half the awake time as overall up time (for instance, 4 hours on battery gives me 2 hours of awake time even if I’m not using the device more than 10 minutes throughout that period) on my Galaxy Nexus. Compared to other devices this most certainly is an anomaly. We’re not sure what’s going on but Google is apparently aware and working on a fix.
For the time being, if any of you have a Nexus S receiving the official update would you please be kind enough to go into the Battery Usage menu and letting us know what your Android OS usage is showing after using it for some time? It would go a long way toward figuring out if this is an Ice Cream Sandwich issue in general or if the two devices are unrelated. [Google Code (Galaxy Nexus), Google Support, XDA via Droid Dog]
