I would say that sounds right. I'd also advise you not to run it down to zero, at least not on a regular basis.

Actually Apple recommends that you do exactly that, once a month:

What's the best percentage to let the iPad run down to? 5%-10%?

A quick couple questions for you:

1. Are you charging it through a computer's USB port?

2. Are you using an iPhone or iPod touch's charging adapter instead of the larger, more powerful charging unit that came with the iPad?

3. Have you recently used any travel voltage/amperage adapters with your iPad?

The iPad will still charge via USB or with chargers designed for the iPhone/iPod, however, the wattage is twice that compared to the one included with an iPhone, and has a higher amperage rating (2.1A). USB ports also work, but charge at a slower rate than using the supplied charger.

If you using the charger that came with your iPad, and are noticing longer than usual charging times, make an appointment with your nearest Apple store's Genius Bar, where they can check it for you. Make sure you do one last sync with your computer before going, as they may replace your iPad under warranty if it indeed is not taking a charge properly.

After my wife traveled to Europe with our iPad, upon returning to the US, we noticed that our ipad was intermittently taking a charge and/or charging very slowly - so we made an appt at our closest Apple store's Genius bar, and upon verifying the charging problem, replaced my iPad with a new one.

I cannot tell you what they will do for you when you go and see them, as it is up to the techs that look at your device, but they have the tools and the knowhow to diagnose and troubleshoot Apple products better than anyone.

i charge through the mains, and i am sure my ipad didnt come with a charger, just a usb cable, do you have a picture of what charger you are talking about so i can be certain.

I charge the iPad through my PC's USB.
Works great with the Asus application

This is the charger that is supplied in all US sold iPad boxes:

The quickest 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.

Hi everyone, I have a little question. I'm a proud owner of an Ipad. Bought it couple of months ago. usually I'm waiting till the battery is dead to fully charge it again and I'm charging it to full (100%) every time. Unfortunately, this morning when my Ipad was still plugged, someone from my family unplugged the charger when the battery was only 60% charged. How it will affect Ipad's battery life? I'm really concerned. Thanks for your help guys

Nothing to be concerned about. The Li-Po battery is memory-free, and can be charged from any %. Apple does recommend a full power cycle at least once a month. They also recommend not to leave it charged constantly, as the electrons need to keep flowing.

Your battery is designed to last approximately 1000 full charge cycles. Disconnecting mid-cycle won't harm yor battery life, and does not count as a full charge cycle.

Here is a link directly to Apple's website regarding battery FAQ's: Apple - Batteries - iPad

So glad I found this thread. I had no idea I should let it drain completely once a month. I knew there was no memory like the old batteries but I had no idea it was "healthy" for my iPad to let it drain completely. Good info and great job sourcing it.

I believe the reason a full monthly discharge is recommended is to keep the battery meter calibrated. If having your meter off by a few percentage points doesn't really matter to you then you don't need to make a special effort to perform a full discharge at all. Just use your Ipad and charge it when needed.
