    Is it normal for it to lose about 3% in 8 hours, without being waken once? (Push email is off)

    Seems about right to me.

    That would not be right if you believe Apple's claim of 30 standby.

    Are you sure you don't have push notifications turned on? I'm referring not e-mail push, but App push. I definitely do not lose 3% in 8 hours. Maybe in a day, but not 8 hours.

    Has this happened many times? Or did you just happen to notice it dropped 3% in 8 hours once? If it only happened once, I wouldn't sweat it. Check the drain over the period of 24 hours (assuming you can put it down for that long :)) to see if it is really that high.

    In use - every 6 minutes should lose 1% if you're getting 10 hrs of usage.

    In "sleep" I'm not sure. But the best advice is if you're so concerned about 3% in 8 hours is to turn off your percentage meter.

    Because I still think it's pretty darn good for any device like this to get 11.1 days (33.3 x 8 hours) of standby.

    30 what? Units are important.

    3% in 8 hours is 12% in 32 hours... or a total standby time of around 10-11 days.

    I checked the iPad site, and didn't see any specs for battery time on standby. Where's your info from?

    I'm losing 10% an hour while in heavy use at about 85% brightness and not even 1% while in stand by for 8 hours. I'm very pleased!

    Does their claim go by push email/notifications and/or fetching ON or by them OFF?

    When I go to bed for 7-8 hours sometimes I lose 20% but that might be the push email draining it.

    I have push notifications and push enabled for both Mobile Me and Exchange... mine will rarely loose a percentage point when in sleep mode for 8-10 hours.

    I get 5 days or MORE of my average use off on once full charge. This includes WiFi always on, bluetooth on, and two hours or so a day connected to a TV via the component out video cables. I leave auto brightness on with the brightness slider set to 1/3 or so.

    Battery life is beyond amazing, both while in use, and while asleep.
