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.

    That is so exactly, 180 degrees wrong. 2560x1440 pixels displayed on a 50 foot screen six foot in front of you will have a very visible grain; displayed on a 10 foot screen, less so. Alternatively, 640x480 pixels on a three inch display will have much less grain than 640x48- pixels on a fourteen inch display. When it comes to the clarity of text, with crisp edges and no visible aliasing, it's all about the number of pixels per inch and distance from the eye. I'm typing this on a 27" monitor and the text quality is noticeably worse than on my iPad 3 or my iPhone 4, because the pixels are bigger Reply

    Also, the Transformer Prime is inferior to the iPad 2 from last year, especially in graphics performance. The Tegra 3 is a dog and NVIDIA has serious catch-up to do with the Tegra 4. How do you expect it to be better than the iPad that was released last week?

    It is funny though seeing someone so ignorant and misinformed talking about "sheeple"

    Are you serious? Have you seen one in person? That display is gorgeous! I'm sorry, you gotta see it to believe it. You can see a clear difference. It's not even close. As soon as I saw the iPad3 you knew right away that there's something different about the display. It looks life-like and the photos are of print-quality.

    I don't know about the Transformer Prime because I haven't seen one myself, but at least check out the thing first before you make a judgement.

    "Looks like a better deal" doesn't make it so. There's no way the battery life is better than iPad. That thing's got the biggest battery pack in the industry. If a competitor have a similar display, how can they possibly compete unless it weighs the same as well?

    Graphics chip? The A5X is the fastest in the industry. No one even comes close.

    I don't know what you smoking, but your list of "Apple pitfalls" is pretty pathetic. At least name the things that are true.

    Can you confirm whether there was continuous data transfer during the 20+ hours Verizon LTE hotspot test? If so, that is incredible battery life! Makes me wonder how long next year's iPad could last with the more power efficient 28nm chipset...

    Hi Guys I don't get the graph/chart above is this in minutes or decimels, cos otherwise the ATP(Balanced) last's for 9 hours 16 minutes. This is really wierd way of testing gear along a time axis?

    Please explain?
  • homebredcorgi - Wednesday, March 21, 2012 - link

    It's in decimal hours. So for the ATP (Balanced), 8.76 hours is equal to 8 hours, 45 minutes, 36 seconds.

    Since 0.76*60 = 45.6 minutes and 0.6*60 = 36 seconds.

    Perhaps it's just me, but IMO, > 15% drop in battery life seems "huge".

    Obviously there's always a trade-off in functionality vs performance vs battery life. Realistically, if I'm using an iPad during the day, maybe for work, the 3rd gen has even less of a chance of making it thru the day, which diminishes it's mobility.

    But it's only a7% drop, I wouldn't call that "huge"... I'm assuming the iPad 2 number is for wifi and a 3G model isn't listed. Still the difference wouldnt be that great since apple listed the iPad 2 at about 9 hours for 3G. Reply

    Yes, but they put an enormous battery in there.

    Hint: the energy isn't all getting converted to light.

    This thing is going to roast your nuts.
