New iPad runs near rivals' heat, 25 hours as hotspot

iPad 2012 defies battery, temperature expectations

Fresh tests of the new iPad have shown that concerns over its temperature have been overstated in light of competition. The range of Macworld tests showed that, despite the extra backlighting and larger processor demanded by the new screen, the current Apple tablet is within a few degrees of the lower-resolution, slower ASUS Transformer Prime and Samsung Galaxy Tab 10.1 LTE. In a few cases, such as under maximum load for over an hour, the Galaxy Tab was slightly hotter.

A similar effect was visible while plugged in.

It wasn't mentioned why other models were hotter. The Transformer Prime's quad-core NVIDIA Tegra 3 was likely responsible for its own temperature hike. As the LTE isn't known to be a major factor in heat, the Galaxy Tab's temperature might be owed to the older Tegra 2 and the thin, plastic design keeping more of the heat around the case.

Simultaneously, cross-platform benchmarks posted last week have netted some surprises about performance. While the new iPad was already shown by AnandTech to be getting more battery life than a non-extended Transformer Prime, even versus the Prime's battery-saving mode, its real highlight was hotspot support. On Verizon, the iPad's 42.5 watt-hour battery lasted 25.3 hours while the tablet served as an LTE hotspot.

Most portable routers, such as the Samsung Jetpack or Novatel's MiFi line, tend to last three to five hours. The sheer battery capacity, and Apple's ability to minimize the power use by the main OS, are responsible for the iPad's performance. Battery life might be slightly better on HSPA+ 3G given its better lifetime in active use.

    Apple Haters

    Love to spread this kind of thing. I've been hearing about it (though I had already read these articles) from people I knew who thought this was some kind of revelation. Once again the media overstates these things for NEWS. If Apple had a PR firm which responded in kind (without it being obviously Apple) that would be hilarious. This Fall MacNN will still be reporting this as Apple's "heat" problem even though they themselves have dismissed this, just like they occasionally bring up Antenna Gate.

    What, an Apple product "shortcoming" that is blown up into a full blown show stopping recall inducing confirmation of Apple's lack of engineering prowess! Say it aint so. This never happens.

    100F. BFD.

    We've all had fevers higher than 100F.

    Heatgate is officially over.

    Well Duh!

    Of course the new iPad makes a great hotspot. Its temperature characteristics have been all over the news this past week.

    Blame the marketing department

    An Apple branded heating pad could be big in the 80+ market. It's a feature. How did the Apple marketing guys miss this?

    Except CR never said there was a problem. They just investigated the problem and said it was hotter than the last model.

    But why let facts cloud your want to throw stones at those who dare say anything that could be taken badly on apple!

    And droid-haters and apple fanboys love to spread negative things about that platform (like overblowing the malware 'threat' and the like). But why quibble.

    No, what we see here is the iDefenders using one article to claim that another article is completely wrong, for no reason then it matches what they say or believe. ("See, it's proof! This pro-apple magazine says so! That just proves that anti-Apple magazine was wrong and lying!").

    Not debunked

    I'd also like to point out that just because the 'competition' has the same 'issue', that doesn't mean there isn't an issue. It could just be that they all have the issue. Just because they all have the issue doesn't mean there isn't a problem.
