One of the things that I have looked at is that it seems that the speed of the CPU doesn't ramp up as fast as it should, or at least, not as fast as I think it should. What does this mean? It means that the CPU governor is taking too long to think about ramping up the speed of the CPU. I eventually see a kernel update in the future that will update some things with the CPU governor.
What will this mean for battery life? Unfortunately, I do see battery life suffering a bit with some CPU governor tweaks since the CPU will be ramping up in speed more often thus causing the CPU to use more power.
So far, I have been able to get my phone to run as close to perfect as I can. I have animations turned on and IMO I'll never turn them back on even if the issues are fixed in the kernel. I've began to like not having the animated screen transitions so having them off is fine with me.
