1) When I unboxed the the new iPad, the battery was at 85%.

2) I put the new iPad into the iPad charging stand I used for the iPad and loaded it up with the software and data from the iPad 2. The charging stand is connected via USB to my iMac.

3) While it was on the stand and loading the apps, I was playing with it and checking out different apps and photos.

4) During this time, the charging indicator has a thunderbolt in it to indicate it is charging.

5) The battery indicator now says 76%

6) I turned the screen off for a couple of minutes and turned it back on and the indicator read 77%. This tells me there is some kind of charging taking place.

7) After leaving the screen on, it started to drop again to 76%.

 

Are other people seeing this?

 

Could this mean that the extra pixels suck electons out of the battery at a faster rate than is put in by the charging cable?


iPad (3rd generation) Wi-Fi, iOS 5.1

    Definitely possible....although Apple says the battery life is about the same or better than the iPad 2.

     

    The other possibility is that the gauge was simply wrong when it said 85%.

    You cannot charge an iPad from the computer's USB port. It does not provide adequate power which is why the iPad comes with a separate 10 watt charger.

    Wrong u can charge an iPad from any powered USB port on any PC of Mac however you can't charge it from the USB hub built into a mac keyboard as there is insufficient power also the iPad won't charge as quickly as it will with the supplied charger.

    Charging Tips

    The fastest way to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter. When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode. Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.

    Hope this helps!

    Enjoy your new iPad

    This is interesting, I'm now noticing a "This accessory is not supported" message when I plug it into the stand. I was not getting that before.

    No, not from "any powered USB port", but only from high--power (0.5mA) USB ports. Not all ports on all computers meet that spec, some laptops have none that do so that part is also incomplete or incorrect. You're correct that a Mac keyboard hub does not have enough juice.

     

    Even from a high-power hub charging the old iPads was problematic and slow and might indeed give you a "Not charging..." indication when you first tried. Generally you could get it to work by putting the iPad to sleep but even then it was slow: A 10W charging source, which is what the supplied Power Adapter is, will simply work faster than a competing 2.5W charging source.

     

    Differences are going to be even more emphasized now with the new 3rd-gen iPad (yes they do need a better name for this thing!). The battery has been bulked up from 25.0 to 42.5 watt-hours, leading to the increases in thickness and weight compared to the iPad2, and it is going to take longer to charge it from any and all sources.

    That is commonly dirty connectors. But it is true - a USB port is not the best charging device you have, and a dock connected to it is likely worse. Both should work, but should not be expected to pump out enough power to charge (very slowly, whilst quite possibly displaying a "not charging" message) the iPad if you are still making it work.

     

    The favoured, most reliable and fastest charger is the one you plug into the wall.  USB ports are not chargers, and should be regarded as a last resort if you do not have the charger handy and can leave the iPad dormant as you charge it.

     

    The battery in the "new iPad" is a monster!

    Yes, I was surprised to see the my iPad draining while plugged in. I've never seen that before with my many previous iPhones or iPads.

     

    Charging has also been exceptionally long. It took around 10 hours to go from 18% to 100%. However, this is the first time recharging. I am curious to see if there will be any uptake on subsequent charges.

    Adding my 2¢ here as well.  Have had my iPad 3 connected to my MacPro's USB hub for 5 hours.  Turned the iPad off, too.  After 5.5 hours, I went from 78% to 96%.  Wow! This really makes me wonder about my future travel with the iPad 3, as it appears charging overnight is not sufficient to reach 100% charge.

    When using the iPad and charging it through the wall outlet plug, it's taking somewhere around 20 minutes to increase the battery indicator by 1%. Ouch.

    Would that be a good idea to use an external battery ? ( like Mophie Powerstation battery)

     

    What do you think?

    Well, I have the new iPad and the battery drains while plugged in with the supplied power supply.  It charges if its asleep but as soon as I start using it (while plugged into wall) the battery drains.

     

    This didnt happen with my iPad 2

    The new iPad will only charge (NORMALLY) with the Supplied Power charger. The current smaller Iphone4 / 4s charger that has been out for some time ,which worked with the iPad2, but will not with the new ipad. The old Ipad 2 Battery was 25W while the new one is 50W. The smaller usb plug charger is simply not "stong enough" to charge the new iPad.

    Both iPad 2 and the new iPad come with a 10w USB charger.
