    I drop about 16% in 8 hours. Not bad.

    This is with BT and WIFI off, but location services on.

    Are you all seeing about the same?

    I see around 5-8%. I kill all programs that run in background. It would be better if WP7 had a wifi sleepy policy so when idle it wouldn't use 3G or LTE data therefore extending battery life. This is probably my biggest dislike of WP7.

    I've experienced about the same, 15%. I was a bit surprised the first night, but only because I never really paid attention on my 3GS. It was probably the same, to be honest.

    How do you kill programs?
    I went from 90% at bedtime last night to 40% this morning, trying to figure out what the deal is. Only had the phone a few days, and I do have the SW update.
    Thanks

    10-15% overnight, Wi-Fi on, strong 4G, 2 emails set to hourly and a weather live tile. Seems excessive but I never paid attention to my iPhone 4 so it could have been similiar.

    Last night mine went down 26% over night. I am going to see what it does tonight. My iPhone would typically only go down 3-4%.

    Also keep pressing the back button to make sure all the apps are closed

    I was under the impression those apps are in suspended state and not actually running. Is that not true? Like on iOS; apps are in suspended state in the RAM for faster launching but are given no CPU time so they aren't actually running.

    Depending on which app, some continue to run. For example, music apps.

    I charge my phone when I go to bed. But normally, I lose around 10%.

    My bigger concern would be is how much data usage is happening while the phone is in idle?
