So you won't be correcting your mistake? Milliamp-hours not milliamps-per-hour. It's one tiny word but it makes a big difference to the meaning.

No mention that all those other tablets cost less. Isn't the most expensive product supposed to be superior? I think my Transformer Prime is superior and cost less. I can customize it, play Flash, thinner, lighter, laptop dock (18 hour battery), live wallpapers, Widgets, Amazon FREE daily paid app. ipads nice screen not sufficient for me. There is no perfect tablet out there, then why not use what costs less and does more?

Because I don't need those things, and find the iPad better for the things I do need. Just my opinion, though.

If I dispute one single point in a post, that should not be taken as an indication that I agree/disagree with any other point made by that poster or anyone else in the thread. Or anywhere else. Ever.

That's fantastic you can do all those things with a Android tablet. So can with mine, but I also own an iPad. The sole reason I own an iPad is for their selection of apps and their hardware. I wanted the high resolution and I wanted the high quality games and apps I like. If you could care less about either of those then I wouldn't recommend an iPad to you. Like Windows vs Mac(OSX) everyone argues based on preference and to justify what they bought. I have a Windows PC. The reason why is because I'm a gamer and I also like to choose my hardware for the games I play. A Mac doesn't have nearly the quantity of games I like nor can I replace the hardware as I see fit. Does that mean that people who choose a Mac are stupid. No. The Mac is very user friendly and has it's advantages for users that could give a crap about the stuff I like. Same can be said for Linux. I use Linux and Windows at work. Both have their attractions to individuals. So really it's just what is best for the individual consumer.

My Dad owns a flip phone because he's old and not accustomed to technology. I own an iPhone. Do I think he's stupid for owning a flip phone? No. It's what works best for him. I work with multiple guys who have Android phones. They don't play games quite as much as me and are more linux lovers. They love their Galaxy Nexus phones. It does everything they want it to do. I have an iPhone 4 because I addicted to the games and other apps that aren't on Android. I love customizing my Android tablet but that only provides me with limited entertainment, so I chose an iPhone.

Basically what I'm getting at is that we all have our preferences and whether your device isn't as good at something as another means absolutely nothing when it boils down to preference. Specifically I don't care if a new Mac cost $100, has 32core processors, 128GB of RAM, and quad video cards. I'm still not buying one because it doesn't support the games I want and other applications that are also unsupported(Let's forget about dual booting for this). Same goes for an Android phone. I don't care if it's waterproof, has an 8core CPU and GPU, 10GB of RAM, and a 1000DPI screen. If it doesn't do what I want then why am I buying it.

If you favor any specific brand over another, you are only hurting yourself. If in some insane future the Mac supports all the games and applications I like, maybe I'll switch. Till then NO! If in some (not so insane) future Android supports all the games and applications I like, maybe I'll switch. Currently they are differant.

It's truly sad what PC Magazine has become.

Funny; on any given day, we're accused of being biased for or against Google, Microsoft, Apple, and any number of other companies. If people can't figure out what your biases are, I think that's a sign that you're doing something right (that is, you have no bias).

Also: we're PCWorld.


Yeah, that was a funny post. Not only did Bozzified not know what he's talking about, he wasn't even aware of the publication he was criticizing. Priceless.

Anyway, I'm glad you ran this story. I was skeptical of the Consumer Reports' story, particularly because they didn't provide an adequate frame of reference for competing devices. From my perspective, that was either lazy reporting or a demonstration of bias on their part. This was a nice piece that presented the facts and served to keep these ridiculous "heat gate" stories in perspective. Well done.

I think that's because reality is more favorable to Apple than anything else.

I hate when that happens.

I like your use of the word "hottest." I've never seen lukewarm temperatures described as hot...

Anywho...In 8 of the 12 tests, the new iPad was less than 5 degrees warmer than the warmest Android tablet. In fact, in 1 of the 12 tests, the iPad was actually 1 degree cooler than the warmest Android tablet and in no case was the temperature difference ever greater than a mere 6 degrees.

In fairness he was only pointing out the silliness of claiming the article was Apple biased.

It seems to me from your figures that the new iPad runs pretty consistently hotter than most of the competition


Let me help you out with that first, I just want to say that I've never seen lukewarm temperatures described as hot...

Anyway, in 8 of the 12 tests, the new iPad was less than 5 degrees warmer than the warmest Android tablet. In fact, in 1 of the 12 tests, the iPad was actually 1 degree cooler than the warmest Android tablet and in no case was the temperature difference ever greater than a mere 6 degrees. Big deal.

although I agree the issue is overblown.

Some interesting points from Ray Soneira (yeah the battery charging guy) about the new iPad...

Expert: iPad heat claims overblown, not a real issue

updated 03:15 am EDT, Thu March 22, 2012
Driving 3.1 million pixels a big job

DisplayMate Technologies Corporation president Ray Soneira has delved further into the technology behind the new iPad's Retina Display as well as its relationship to the battery and come up with a simple conclusion: the new iPad, operating normally, should run a bit warmer than the previous model. He calls the thermographic portraits circulating the web "overblown" and says the extra heat is the natural consequence of increased power.

The third-generation iPad uses 2.5 times as much backlight power to illuminate the new display at the same luminance levels as the previous model, Soneira found. The high pixels-per-inch (PPI) ratio of the new display makes the LCD have a lower light efficiency and thus power efficiency. The doubled number of LEDs also give off 2.5 times as much heat, but remarkably the new battery in the iPad manages to (mostly) compensate for the increase...

...He tested the new iPad by running it at maximum brightness and found that the battery was exhausted in 5.8 hours, 20 percent less time than a similar test with the iPad 2, indicating that the increased resolution can also generate more heat, which contributes to battery drain. Soneira also found that maximum brightness consumed 65 percent of the total power used by the device, stressing the importance of both heat-generation and power-consumption in test results. Tests with the brightness at normal levels (middle brightness) showed the new iPad almost exactly matching the previous model, proving heat generation of the display can play a major role in the device's efficiency.

The New iPad Display, Tested and Praised
By HARRY MCCRACKEN | @harrymccracken | March 20, 2012

My friend Dr. Ray Soneira, president of DisplayMate Technologies, has been evaluating computer displays for a long time. In recent years, he’s turned his attention to smartphone and tablet screens — and he’s published a piece that compares the new iPad with the iPad 2 and the iPhone 4.

He likes the new Apple tablet’s Retina display. A lot. In fact, he says that the company’s claim that it’s the best mobile screen ever isn’t hype:

Apple has taken the very good display on the iPad 2 and dramatically improved two of its major weak points: sharpness and color saturation – they are now state-of-the-art. Our lab tests and visual tests agree with Apple’s claim that the new iPad has “the best display ever on a mobile device” so we have awarded the new iPad the Best Mobile Display Award in DisplayMate’s Best Video Hardware Guide. But there’s more…the new iPad’s picture quality, color accuracy, and gray scale are not only much better than any other Tablet or Smartphone, it’s also much better than most HDTVs, laptops, and monitors. In fact with some minor calibration tweaks the new iPad would qualify as a studio reference monitor.

So now I don't know what to think about Dr. Soneira, maybe he's really good with displays and not so hot with batteries.

Did PCWorld calibrate the infrared thermocouple for emissivity factor? That factor depends on the object that you're pointing at. The default according to the manual is 0.95, and that needs to be changed depending on the "reflectiveness" of the object that you are trying to measure. (-25 to 999°F, 12:1 (D:S), ±1% accuracy, laser sight, fixed emissivity (.95), hard case)

My company actually bought a $40,000 temperature measurement camera, and it has automatic emissivity correction and high resolution. I don't think a $500 infrared would have it. A black case, a white case, and a silvery reflective case will make a huge difference if the factor is not adjusted correctly.

It's difficult to take the results for what they are if the methodology of testing is wrong. What color of the tablets were used? The infrared camera needs to be calibrated for the different color cases. If the Samsung Galaxy and Asus Transformer Prime were in black and the iPad 2/3 were white, then the readings will likely to be lower on the iPad 2/3 simply the emissivity factor for white is less than that of black. http://en.wikipedia....wiki/Emissivity

There's probably a good reason why his company is called DisplayMate and not BatteryMate :lol:

I doubt it, but the rear center temperature reading would be accurate, because there's a black rubbery plastic apple shaped spot in the middle. I did my own testing with a Fluke 561 and compared the result with a K-type thermocouple and found the medium setting was the most accurate for the aluminum areas. I would expect the new iPad to run hotter than all tablets simply by virtue of having the highest battery current needs.

LOL..for your information iPad doesn't need help. No matter how hard haters tries to destroy it, people still buy and love it..because they know better...you can say whatever you want but the sales we'll just keep coming and you'll be more pissed. And it's not just PC Magazine that did the test..here's another one from wired.
