What are some battery lives people are seeing? Personally, I've found almost no reason to clamor over ICS. The pulldown curtain I have on Gingerbread right now with a scrolling row of various toggles is far more useful. Samsung's integrated slide-your-finger-along-the-top brightness adjustment is incredibly useful. I'm still not sure how I feel about the task manager option, it feels limited and offers no ram/cpu usage data and feels more like a knockoff of the IOS task manager rather than something useful. The only thing I've found significantly more intuitive/useful is the system settings.
These are my opinions, no need to argue, nothing against CM9.
But it is CM9 that has brought ICS to our phone, and I have to feel that a lot of deep settings and drivers have not been fine-tuned to our phone to maximize performance and battery the way Samsung intended. After popping in a fresh battery, I watched my phone lose 50% in 10 hours without my even touching it. Battery stats indicate that the phone was not waking up, ruling that out as a factor. Fine tweaking adjustments to cpu and ram yielded similar, if not worse, results. What kind of battery lives are other people seeing?
If you know my roms, you know I strive for battery life. My phone is a tool, and to be a useful tool it needs to have power.
