The battery life doesn't seem a lot different. I think it is too early to say and I have been playing some power hungry games

Lot of apps keep crashing, but that is expected till the developers update the apps.
Also I think there is some lag after using the phone for a while, again I have Nova launcher, could be the launcher.
