regardless of awake i think if the phone lasts 8 hrs with moderate - heavy usage be happy. i only get 6hrs. my phone has been off the charger since 6am it is now 11am and my battery is at36% with a 64% wake time. im pushing my exchange mail which is probably killing the battery. there are probably at least 10 apps causing the phone not to sleep so it will be hard to pinpoint.since writing this post my battery dropped another 2%. its up to sprint and htc to fix this.
