    Hey all,

    I have had my iPad 2 plugged in charging for sometime now...and the battery percentage has shown 99% with the charging bolt symbol for many hours now. It has yet to show 100% with a plugged in symbol and my iPad 2 has been plugged in for about 6 hours now.

    Is this normal or a problem?

    Thanks.

    It's normal. The percentage indicator is a pretty rough guestimate. I don't think battery chemistry is that precise. This happens with my iOS products sometimes.

    And it happens with the MacBook (pro) line as well.

    Completely normal.

    Who cares.. 99% is the same as 100% anyway..

    Two pieces are at work: You need to calibrate by allowing the iPad to die completely then recharge for 7 hours. The charger trickles and in order to protect the battery it will vary 98%-100% when fully charged.
