    OK, I checked my new usage stats. Its 3 hours and 58 minutes usage with 3 days and 21 hours of standby. OK by 1.0.2 standards, but before I used to get upto 6 hours of usage and 4 days of standby. Hope Apple resolves this issue in the next update

    Kennyboy3, good eyes! I had noticed that the meter sort of "jumped" after 1.02 but never really thought about the implications on charging or tried to see if it was repeatable. Now that you've posted, I've done some testing and I totally agree with you, not only is it repeatable but I feel that if you don't "fix" the jump the phone stops charging before it's full.

    Only if you report it as a bug they might

    I can replicate the 'meter jump' but unfortunately after a charge cycle like this I don't gain any extra battery life.

    I'm thinking this is just a display initialization bug rather than a true 20% undercharged.

    Bug reported last week for my phone...lets see what happens in 1.0.3 :-/

    Replying to myself but I started messing around to try and replicate this, which I can - every time, then I had a sudden thought, I had been mostly charging from the wall outlet in prior firmwares.

    I plugged the phone into the charger instead of the computer dock, the battery showed the same as it did after the power cycle in cradle charge so I let it power off(standby) by itself then turned it back on and lo and behold another 20% is gone..in fact the indicator has turned red.

    This leads me to believe that the issue is something to do with either:

    USB power on my macbook (unlikely?) or the charge cylce gets all messed up by the sync. process somehow.

    I'm going to let it charge on the charger from the wall outlet and see what usage I get over the next 2 or 3 days.

    Au Contraire mon ami...I've noticed the same 15-20 jump just after putting in the dock. I'd bet the software giving the battery visual was changed. Actually battery charging/discharging has probably not changed.

    Hey Steve, I finally tried what you said in an earlier post:

    "I'm going to try that with my phone. If it's consistent, I should be able to charge my phone, turn it off and see the meter drop 20% when I turn it back on."

    And it did exactly what I was afraid it would do.

    (1) I placed iPhone in dock
    (2) Battery meter jumped 15-20%
    (3) I let it charge overnight from this point
    (4) The next morning it said the battery was fully charged (both plug and glow), but is it really?
    (5) I turned iPhone off (with red slider) and back on, all while remaining in dock
    (6) When iPhone powers back up 15-20% is gone from the battery meter, indicating that the phone was not actually fully charged
    (7) Leaving it in the dock it continues to charge until the plug & glow appear again eventually

    I don't guess it's a huge deal to power down and back up every night, but I hope a future update fixes this. I have filed a bug report.

    I am convinced that this is "real" because I can notice a difference in the speed at which my battery drains the next day depending on whether or not I have "corrected" the battery meter (by powering down and back up) prior to charging.

    Yes, I can reproduce this consistently too.

    Are you using the wall charger or charging from the computer? I seem to get a much less buggy charge cycle using the wall charger.

    I charge using the wall charger.

    I plugged into my iBook yesterday to sync up with some new music that I had purchased and noticed that my battery meter jumped up when I plugged into the laptop USB also.

    There is another iPhone in my household and it behaves in exactly the same manner since 1.0.2, also using the wall charger.

    Same here, as soon as i plug my phone even into the wall charger, the battery jumps up about 10%, If i reboot the phone, it starts charging back where it was at before i plugged it in. This *****, Now every time i charge my phone i have to plug it in and reboot it. Great, thanks for 1.0.2, LOL

    Can anyone else confirm that there battery charging is behaving in this manner?

    Thanks, Scott K.
