Apple, Antennagate, And Why It's Time To Move On

"There's an awful lot of hoopla about that iPhone 4 antenna." Why yes, there is. And while there's much to criticise about Apple's response, we're glad to see they've stopped pretending the problem doesn't exist.

Apple spent most of the time last week defending the iPhone 4's antenna, using both data and rhetoric that was impressive in its scope.

Defence No. 1: Life Sucks

Apple's primary defence is that every phone's reception sucks when you hold it. The company line from the very beginning: "Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone."

Apple showed this "fact of life" using three non-iPhones in particular: the BlackBerry Bold 9700, HTC Droid Eris and Samsung's Omnia 2. The phones are death gripped; the bars plummet.

It's true, you can readily demonstrate attenuation on a lot of phones. Just the handful of phones at my place, where I have mediocre coverage, show that. Gripping the Nexus One on the bottom causes a bar to drop; the BlackBerry Bold 9700 drops three bars, precisely as demoed by Apple; neither the Droid X nor the Evo drop any bars held with a normal death. (You have to hold the very top of the Droid X or Evo to knock off a bar.) The iPhone 4, upgraded to 4.0.1, touched in the single weak spot, drops two bars.

The difference is that the other phones, with the exception of the Nexus One, require a grip - your hand has to wrap around where the antenna is located to cause noticeable attenuation, while touching the iPhone 4 at a single point disrupts the signal. (As RIM and Nokia were quick to reply when Apple singled them out.)

Which is exactly what Ryan Block asked Apple's Bob Mansfield about at the post-conference Q&A:

Q: How does touching the corner with a single finger seem to cause this issue? It's not just a grip, it can just happen by touching a single finger.

A: Your body is a pretty effective signal absorber. When you make contact with that phone, its performance in contact with you is less than its freespace performance. It's a way to attenuate the signal by some amount.

Then why would cases, which you wrap your hand around, be a working solution to the problem? As an engineer told us, the fact that bumpers are the solution shows that the real problem has to do with skin contact with the iPhone 4's antenna - not attenuation simply from signals passing through your body. Rather, it seems like the antenna's impedance is changing as a result of the skin contact, so it's possible that a thin electrically non-conductive coating could solve the problem. (Perhaps this is why Steve promised to re-evaluate the issue in September.) That's why the other phones don't have a signal loss from attenuation that's quite as profound.

It's also why Steve Jobs offered his own "pet theory": that not enough cases have been sold for the iPhone 4. That seems a little silly, as the iPhone 3G and 3GS didn't have a single weak point, affected by skin contact.

Defence 2: Everything Is Just Great

The iPhone 4 is using "a very advanced new antenna system". In fact, Steve says it "is a more advanced antenna than ever has shipped on a smartphone before". And later he says, "looking at the data, we don't think we have a problem". What data is that?

Well they've spent $US100 million on a very fancy facility with 17 different antenna characterisation chambers to test phones.

Only 0.55 per cent of all iPhone 4 users have called AppleCare about the antenna or reception. (This includes Genius Bar visits, apparently.) That's around 16,500 complaints, out of three million iPhones sold. "Historically for us, this is not a large number," Steve says. (What is a large number then? A normal number? He does not say.)

For comparison, HTC says that the Droid Eris - one of the phones Apple used to show that attenuation screws every phone - has fielded reception or antenna complaints from just 0.016 per cent of all users. (It's possible that it's harder to find where to complain about the Eris.) Oh, and the return rate for the iPhone 4 is just 1.7 per cent, versus 6 per cent for the iPhone 3GS. Happy campers!

But then there's this: "I can tell you since we're being totally transparent, that even though we believe the iPhone 4 antenna is superior to that of the iPhone 3GS, I must report to you that the iPhone 4 drops more calls per 100 than iPhone 3GS." The rate of iPhone 4 dropped calls is less than 1 per cent greater than the iPhone 3GS.

That number is fuzzier than it seems, too. Less than 1 per cent could be anywhere from .01 per cent to .99 per cent. Presumably, Steve would use the smallest number possible - something like less than one half of one percent. So let's round up to 1 per cent. Adding another percent to 100,000 dropped calls is an additional 1000 dropped calls. Or, put a more damning way, if the iPhone 3GS dropped 1 out of every 100 calls, the iPhone 4 could drop up to 1.9 out of every calls - it's possible we're talking a nearly double dropped call rate.

Still, it's a pretty curious thing. Shouldn't the iPhone 4's "very advanced antenna" result in fewer dropped calls, not more, especially if it's superior?

Defence 3: We Made a Little Mistake, We're Being Exploited, But Now Everything Is Fixed

If you want to boil it all down, Steve says, "The heart of the problem is: smartphones have weak spots. We made ours extremely visible. Some took advantage of that to demonstrate it. It was very easily demonstrable. We screwed up on displaying too many bars and made that demonstration more theatrical than it needed to be."

Apple says they've been incorrectly displaying the bars, so they've fixed it. "We screwed up on our algorithm...Our choice is to put the correct algorithm in, which we've just done." It's true, they have corrected a real issue, as Anandtech beautifully shows. The iPhone's signal bars painted a much rosier picture of the signal situation than reality, and the compressed dynamic range of the bars made them only slightly more accurate than licking your finger and sticking it in the wind. They're now far more meaningful and evenly distributed indicators of signal than they've been for the last two years. But why didn't Apple do this sooner, if it was so terribly wrong?

Well originally it made the iPhone's reception look better, that's why. It stretches credulity to super-spandex levels to think it slipped by Apple's engineers for years, undetected. (After all, they're making the most advanced antennas in any smartphone, with $US100 million testing facilities. They didn't notice the iPhone used a juiced signal indicator?) The flipside of pumping the bars, what came back to bite Apple, was that the signal drops looked worse than they actually were.

There's a weird subtext about transparency and victimisation through all of this too. A sense of, "See what happens when we're transparent?" Apple's not known for being very open, so it's interesting that when Steve talks about the pains they're taking to be transparent more than a couple times - "we went through a lot of trouble to put this beautiful line in the steel" to mark the weak spot - it's interspersed with comments like the one above and "When people are criticising us, we take it really personally. Maybe we should have a wall of PR people keeping us away from all that." As a journalist, this is laughable: Apple has one of the most opaque and impregnable walls of PR people in the industry. Apple's silence, enforced by PR staff who will clam up at the slightest hint of someone going off-message, are legendary.

That's why you'll never get a straight-up apology from Apple. They're smart enough to know that would open the door to a class action suit and too proud to throw themselves on their sword over a single irritating-if-minor issue. It's just not their style and never will be while Jobs is in charge.

Defence 4: It's a Little Problem

See all those numbers? It's a little problem. We work hard. We love you. We make great stuff. We're giving out free cases. Stop talking about this. Steve says, "We've been working really, really hard for the last 22 days to try to understand what the real problem is, so that when we solve it, we actually solve it, rather than just putting a Band-Aid on it."

This elides the fact that cases are a Band-Aid. Almost literally - it's a piece of material affixed at top a gaping hole in the phone. There is a problem when people's skin comes into contact with the weak spot on the phone. On every single iPhone 4.

The Upshot

So! There is a problem with a particular point on the iPhone 4's external antenna. When you touch that single point with bare skin, you lose signal strength - around 24dB, to precise. The old method of displaying signal bars did made it look worse, because of the way it compressed the dynamic range. The free cases will help - significantly, according to Anandtech's numbers, but it's not a permanent fix. The vast majority of the time, it does offer better reception.

Apple's done the right thing, for now, by fixing the iPhone's signal display, which might be the best of any smartphone - even if it's a little ridiculous that this is what it took for that to happen. And the free cases do ameliorate the antenna problem, even if they don't fix its cause. Maybe, as Jean-Louis Gassee suggested, it should've been framed as a tradeoff from the very beginning. Informed consumers, radical transparency, crisis averted. Everyone would've talked about how much they love their iPhone anyway from the very beginning.

The iPhone 4 is a fantastic phone - among the best yet made - and the antenna issue may dent its crown, but doesn't dethrone it.

    Hmm. Fascinating. Something happens with Apple, it's 'time to move on'. Something happens with Microsoft, we just poke fun until it's so overdone and boring I think my brain will implode from reading it.

    I can haz dubble standards?

      I was thinking the same thing... if moving on would mean that some of the Apple fanboys would eat some humble pie, I might, you know, move on... unlikely.

      when apple has made around 1000 stuff ups likes Microsoft and go into denial for years on end, get back to me.

        I'd like to see you list 1000 stuffups Microsoft has made. I can only think of Windows ME and Windows Vista - BOTH have already been acknowleged by MS as "not good enough".

        1000 stuff ups

        of hand here we go:

        windows 3.1, windows 95, win 98, BoB, windows mobile 6.0 and 6.5 the zune, the kin, all the crap tablets that didnt sell, and every single virus they didnt address within 22 days... that about sums up 1000000000000

        You want 1000 stuff ups?

        Open Start > All Programs > Windows Update...

        There's your list of 1000 updates to try and fix 1000 stuff ups....

      Remember the slogan 'It just works'? Well does the iphone 4 just work? No. Does the latest iphone 3 software update work? No. Did the screen on the imac just work? No. How can Apple suggest the iphone 4 problems relate merely to a 'stunning' finding that their software showed the wrong number of bars on the phone? Why are they then giving out phone holders if it is merely a software problem? The ACCC should be looking into this. Moreover, if I were Microsoft, I would launch the new windows phone with an ad which mimics the Apple imac ads, but this time the fat guy will have the last laugh with the 'cool' guy holding an iphone wrapped in rubber.

    That would explain all these manuals by all those companies saying how to hold their phones then to stop signal loss...

      please note: "hold the phone like you would ANY OTHER PHONE" i.e. naturally!

      note the placement of the antennas are out of the way of where your hand would naturally be!

      and there IS the undeniable design flaw that allows the iphone4's antennas to be bridged, something that does not effect other phones.

      All phones will lose some reception if dethgripp'd in a particular manner. This is why they are generally designed so that when held naturally the antenna is out of the way and not effected.

      NO other phone that I know of loses reception when lightly touched with your finger on one spot. And secondly it's a spot that one is likely to touch when holding the phone naturally.

      The "every other phone has this problem" argument just doesn't fly. I like the iPhone, I'll probably still buy it. But there's a difference between thinking a product is good but has problems and being a dogmatic fangirl and denying that anything apple make could ever have a problem.

        "being a dogmatic fangirl and denying that anything apple make could ever have a problem"

        when did that person ever say anything in these forums to make you draw that conclusion?

        I myself have had a fair few apple products fail me in the past 20 years, but they were always addressed, and in perspective of other windoze stuff and other tech gadgets (xbox 360) they were never ignored for years on end and addressed quickly...

        How long did it take MS to redesign the 360.. 3 years!! How long to fix the MS EXCHANGE bug in server 2000? 8 months! TIME for a little perspective!

    I love it - Apple screw the pooch on the very thing a mobile PHONE has to do first and foremost and the fanpress set cycle to "spin".

    Rinse and repeat.

    wow some people are moving on arnt they..... must be a slow news day...

    Now they're planning on releasing the phone in new markets presumably with the same known problem.

    They never denied there was a problem.

    Gizmodo, on the other hand, tried to whip up a frenzy as payback for the stolen iPhone debacle.

    Too bad for you, but the vast majority of users will never be affected.

    It is remarkable that they stuffed up the reception reporting algorithm for 2 years. What a load of crap. They would have specifically used that so the phone appeared to have better reception. That decision certainly did come back to bite them in the ass. Hilarious that they think people believe that 'we just discovered this'. Someone at Apple would be smugly smiling (more than usual) and thinking I told you so

    Great write up Matt.

    I guess one of the reasons Apple doesn't like being open and transparent is that it makes it easier to see through their marketing nonsense. Facts have a tendency to get in the way of lies.

    thing is, we HAVE moved on... to Android, WebOS, Win Phone 7, etc

      WIN PHONE 7, LOL!

      Windows Phone 7: Don't bother with this disaster...,0&source=footer

        I read the article. That article was written by Galen Gruman, former Executive Editor for MacWorld. A bit biased I would think, especially considering how negative it was and how it was written.

        If you read the comments in the article you would see the majority of commentors are calling him out for his dishonest and ill-informed article.

        As one of the very few negative opines of Windows Phone 7, you're really grabbing at straws with this one.

    I remember when I first heard about the bumpers when the iPhone was unveiled and thinking "That's weird; usually phone companies (especially Apple) leave that sort of thing to third-parties." As soon as all this brouhaha appeared about the antenna placement I realised why they were making it themselves and pushing it along with the phone. Now they're saying 'Ok, just to prove there's not an issue we'll give them out for free...'
    Of course, I'm probably just being biased against Apple, and/or paranoid by your reckoning...
