Hot on the heels of our Retina Display analysis we have some more data for you: battery life of the new iPad. The chart above is our revamped web browser battery life test that we introduced in Part 2 of our Eee Pad Transformer Prime review. Despite the huge increase in battery capacity, battery life seems to be a bit lower than the iPad 2. The drop isn't huge but it does echo what we've seen in our subjective testing: the new iPad doesn't appear to last as long as the old one.

The drop on LTE is in line with what Apple claims you should expect: about an hour less than on WiFi. 

Now for the killer. If you have an iPad on Verizon's LTE network and use it as a personal hotspot (not currently possible on the AT&T version), it will last you roughly 25.3 hours on a single charge. Obviously that's with the display turned off, but with a 42.5Wh battery driving Qualcomm's MDM9600 you get tons of life out of the new iPad as a personal hotspot.

    Do you have to 'only' do something to benefit from it? It has the best normal battery life anyway, excluding the iPad 2. Just another benefit. Reply

    Wait... so you mean there was an easier way to do it rather than for me to buy a 4G Ipad for 500 and WiFi Ipad for 800? I generally keep the 4G Ipad turned off and use it as a hotspot so I can get better battery life on my WiFi Ipad.

    If only I could have it all with just one Ipad.

    Verizon doesn't have a cap and they don't throttle. If you use more you move to a higher bucket of GB. They will even back date you so you don't pay a per GB overage. Might as well get used to it. Wireless network capacity is a scarce commodity. You don't complain that electricty, water, or natural gas are generally metered (even though there are still plenty of people that have unlimited for those too). Reply

    Amount it takes to charge? Reply

    Yeah, I'd love to see the amount of time it takes to charge using the AC adapter, Mac USB port, and PC USB port from 0-100%. I suspect that standard spec 500mA are so pitifully slow at charging that they aren't useful anymore. I never bothered using the AC adapter with my previous iPads but I might have to this time. Reply

    0.5A * 5V = 2.5W -> 2.5W * 80% efficiency = 2W -> 42.5Whr/2W = 21 hours --> charging via normal USB takes one day. Charging via 1A charger probably half a day.

    But I'm also curious to see real life numbers.

    iPads of any generation won't charge at .5A. The included adapter is 2A. I charged from 8% this weekend, it was about 6 hours.

    Charge time is the only drawback I have experienced from upgrading from the first gen.

    Agreed. Sounds like this is one of the big negatives of the new display and the corresponding 70% increase in battery size. Also, is there any way to speed up the battery charging process? Like using an Innergie 3A/15W wall charger instead of the supplied Apple 2A/10W charger? Or does that not do anything? Reply

    I had to become a member to correct that chart. It simply is incorrect.

    I own an ipad 3 32g 4g Lte Verizon model and I properly calibrated my battery and I am getting 11 hours battery life with wifi enabled. Please correct your data and run a proper test next time.
