Using the new bumble bee governor and stock voltages running at 250 to 800 I've gotten 20 hours and 30 minutes with pretty heavy use, though data was off for 8 of those hours while I was asleep. But, I've had over half a dozen phone calls, lots of texts and emails, used google maps, and browsed for about half an hour before the battery got to 5%. The phone its a bit sluggish when waking sometimes, but other than that no issues answering calls and it's almost as fast as prime using interactive.
Good job. Thanks for a great kernel.
