If you want great battery life, customizations, and also stable overclocking to 1.35Ghz, you might just want to give the Apex ROM a try, which I have been using for couple days now and simply love it.
First, battery life is great on the Apex ROM, you can expect full 2-3 days.
Second, there’s lots of customizations you can do with Apex Customizations option in Settings.
Third, you can overclock to 1.35Ghz with its native CPU settings without use of an overclocking app like SetCPU.
Overall, everything is built-in and again, I love the battery life I get on this plus the performance.
And lastly, it’s available for both GSM and CDMA versions of Galaxy Nexus so you have nothing to lose.
Try out this ROM and let me know what you think, I think you will be very happy.
