Last nite I left my phone off the charger just to test. It went from 80% to 40% in about 7.5 hours (1am to 8:30am) with only Bluetooth and hourly email synching on (I received 5 emails throughout the nite, 50kb in size max). I do not have Juice Defender (just recently disabled it). I will be doing testing with it installed as well. This is after turning off DRM services and toggling airplane mode from on to off. If you have the information, can you please post what your battery usage is during standby, and what, if any, extra wireless services you have running (bluetooth, wireless, 4g, Synch etc...) and any other pertinent info. I just don't agree that this should be normal battery performance while the phone is doing nothing, so I would like to compare with everyone else. Thanks.
