Just a quick warning, since installing Google Chrome on my S3 I'm constantly having a suspend_backoff kernel wakelock. This wakelock isn't in BetterBatteryStats untill you launch Google Chrome and exit it. Turn of your screen for half an hour or so and check back in BetterBatteryStats, you now will see the suspend_backoff kernel wakelock for the whole screen off time. Taken me a whole Saturday to find out it was Google Chrome causing this issue, so just a quick warning. I don't know if you guys have the same issue, but it's worth a check because it kills your battery.
