3G Performance

The first thing I did after getting the iPhone 3G was to run a 3G performance test on it. I published my findings immediately.

I’m pretty sure that I can answer the “should I upgrade my iPhone?” question in this page alone, so let’s practice being succinct!

Without a doubt 3G is a lot faster than Edge on the iPhone, but it’s worth setting proper expectations; here are the raw numbers:

Edge will download at around 110kbps, 1Mbps for 3G and 3Mbps for WiFi. Fast enough for web browsing, right? Wrong.

Let’s look at some real world tests:

I loaded the iPhone optimized Facebook home page, on Edge it took 9.2 seconds, 8.5 seconds on 3G and 3.8 seconds on WiFi. What’s interesting is that the initial connection to the server seems to take much longer on both Edge/3G than on WiFi. I originally hypothesized that this may be a DNS issue on AT&T’s network, but even visiting sites using their IP address alone showed the same lag before the page started loading. I’ve seen this as long as I’ve had an Edge capable phone, so it’s not an iPhone specific issue - but it does eat into the usefulness of 3G.

Next up was Digg’s iPhone optimized site:

Here 3G offers a more significant performance advantage, but it still takes around twice as long to render a page as WiFi. Again, I suspect that the problem here is the initial connection to the server.

Finally we have a image heavy site, a little hardware website called AnandTech:

With an image heavy website we’re bound more by download speed than by latency, so while Edge took 45 seconds to load, 3G only took 17 seconds, and WiFi barely had an advantage at 13.5 seconds.

If the majority of sites you use on your iPhone are small, text heavy sites, then you honestly won’t notice a huge difference between Edge and 3G, and it won’t feel like WiFi anywhere to you. However, if you use sites with more images and content to download, 3G will feel more like WiFi and Edge just won’t cut it.

    And naturally, the 'competitor' that you chose, the N95 supports 4G does it? Don't make me laugh. I used to have an N95 and I upgraded to the iPhone after having used one and being uber impressed. The N95 might have a longer spec sheet anda better camera, but for usability the iPhone is so far ahead its almost comical. People seem upset that Apple got something right pretty much first time which all the other manufacturers still can't do. Just look at the mess that is Windows Mobile.

    Robin,

    1. I'm talking about N95 8GB and not N95, there is a quite big difference. But nevermind - you can pick N96. It even has built-in TV-tuner.
    2. I never said N95 supports 4G. I was talking about the differences between North America and Europe for example. 4G is for my laptop and stationary phone.

    Besides I never said that iPhone is a bad phone at all.

    For the clumsiness - I agree.

    4G is available here (Bulgaria), though we're the only country in Europe with 4G coverage (yet). I mean nation-wide WiMAX coverage over 4G equipment.

    As for the install base - compare the number of Symbian applications over iPhone apps...

    A-GPS - I've been using this for long time and I can't even imagine that the first iPhone is lacking this. So A-GPS - no news, welcome to the club.

    Accelerometer - welcome to the club also.

    Photo - 2 MP means no camera at all

    Flash support - this feature is mandatory for decent browsing experience.

    Battery - how usefull is a phone which you should recharge twice a day (in case you're using it for more than talk and that's the big idea with iPhone)

    FM Radio, Java, etc... just read this: http://www.gsmarena.com/compare.php3?idPhone2=2088...">http://www.gsmarena.com/compare.php3?idPhone2=2088...

    Epic review. This phone looked like a steal at $200, but man it really is spendy once you do the math for those 2 year contracts. For now, I think I'll hold off until I can find out what's in store with the Google phone.

    There will be no "google phone". You'll just get whatever the various manufacturers do with android and last but not least the telcos feed you - no magic google bullet that will make everything glorious.

    And yet, there are already dark clouds on the android horizon. Open source they said? Why is it that only a handful developers under NDA get SDK updates and the rest is forced to use outdated, bugged versions?

    More about it and a petition can be found here:

    With that in mind, android could face some major delays... big chance for nokia (and their newly founded, open symbian alliance) and apple to steamroll over googles android parade before it really took off.

    With the phone, that is. The article is exactly what I've come to expect from Anand, nothing less.

    I will admit I am normally an Apple hater. I lady I know at work made her husband get her this as soon as it came out. She was showing it off to everybody on Monday. I admit it was pretty darn sweet and had a ton of useful features. When I went to the AT&T site and saw I could get the 8 gig version for 200 bucks I was astonished.
    Of course, AT&T will probably have some way to leech a ridiculous amount of money from me with the service, but the phone itself is great and a really good deal right now.

    Maybe the webpage load times are specific to your area? Ars's findings were significantly more in favor of 3G: http://arstechnica.com/reviews/hardware/iphone3g-r...">http://arstechnica.com/reviews/hardware/iphone3g-r...

    And I agree with the above posters, you should know better than to complain about a specific carrier's reception without heavily qualifying it.
  • GTaudiophile - Wednesday, July 16, 2008 - link

    I refuse to buy one until I can use it (legit) with T-Mobile.
  • Arc 0V - Thursday, July 17, 2008 - link

    Same iPhone should be on more carriers than AT&T but oh well. On the other hand I love my Verizon service. I travel a lot with family and friends, and my cousin and a friend have T-Mobile and the other has AT&T, and I can not count how many times I have service when they don't (wow lots of ands). By travel I mean like out of state constantly either driving or flying.

    Yes 3 articles on Iphone. Sad, pretty sad change of course for the site.

    When can we expect to see a preview, review, and feature set of the Ford Escort, or Bud Light with Lime? I await with anticipation!
