More iPad battery worries surface

Owners of the new iPad are apparently damaging their shiny toys by doing something as drastic as charging it.

The Apple bulletin boards are full of punters who have noticed that the tablet is running out of juice quite quickly.

DisplayMate Technologies noticed that the iPad was showing discrepancies between the charge indicator and the power available.

According to the Sydney Morning Herald, the only way to get a full charge is to leave the iPad plugged in for an hour or more – but that could damage the battery.

DisplayMate president Raymond Soneira warned that if you stop charging the iPad when the indicator reads 100 percent, you’re really only about 90 percent charged.

He said that there was something wrong with the battery charge mathematical model on the iPad as it tells the world it is full up when it isn’t.

Things are complicated by the fact that the new iPad takes longer to charge than the iPad 2 because of its 70 percent larger, 42.5-watt-hour battery.

That would be no problem you could just charge the battery for longer right. But Apple has issued a warning sayin that if you charge it more than when the battery indicator reads 100 percent, you could actually harm the longevity of the battery.

Battery problems are more acute on the iPad because if a battery is knackered you have to take it in to the Apple store to be fixed rather than replacing it yourself.
