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.

    Like it or not, the iPhone is hardware.

    AnandTech is run by Anand, and whatever strikes his fancy (be they MacBook Airs or iPhones) gets reviewed.

    Yes its hardware, so is a toaster..I away his review on the latest model toasters that come out, as well as the top of the line flashlights... i rest my case.

    Its sad that you aren't realistic enough to know that currently lots of people are looking for a decent and unbiased iPhone 3G review, and Anandtech (A technology site I recall) offers a very good and highly technical review, the best I've seen. Where's the issue there? Are you annoyed that the iPhone is again in great demand and in the news? Its hardly the iPhone's fault that the HTC *fill in this weeks model* garners about as much press attention as a comeback by Kelly Clarkson, its fundamentally outdated and playing catchup to the new kid on the block.

    You really need to roll over and die.

    you ungrateful morons don't seem to get a simple fact. this site is FREE

    Anand & Co. owe you nothing & yet they keep putting up good/great articles

    Lately all i see is whine & cheese about how anandtech has lost its hardware focus , while commenting in 'the third' article of hardware

    more often than not this is a one stop place for getting your info. don't like it , don't click.

    and im not a mindless fanboy - someone here was recently criticizing the AT staff over something , but he made clear , precise & constructive points why he felt so - and thats a good way to go about it. your stale WAAWAAWAA is just a stupid annoyance

    VERY well said. Almost the exact words I was thinking.

    Keep up the EXCELLENT work Anand and Staff!

    What he said, roll over and die.

    What are you talking about? I think that Anand's article provides one of the, no, the clearest and most consise iPhone article, and I'm done hunting for them to learn some more random details that I may have been interested in. His conclusion was not the standard three paragraph garbage you see on most other review sites - thanks for the really in depth final conclusion and summary.

    The first and last good iPhone review I've read, coming from an iPod Touch user for the past three months.

    What am i talking about? I guess you are oblivious to the fact that the iphone is a niche market. Like every smart phone out there. Yet they review a iphone and no other phone? You know why they don't review others phones..because there are millions of sites that do that all the time.

    Stick with actually HARDWARE analysis like next to Anandtech on top of page. Leave the phones/cars/apple related stuff/ game reviews, etc to other sites who do it 24/7.

    I think there needs to be some emphasis in the section dealing with reception on the fact that coverage is STRONGLY influenced by where you are. When I was at college, a large number of my friends were Verizon customers, but most dropped Verizon and switched to either Cingular/AT&T or regional carriers because Verizon coverage in the area was practically nonexistent. None of their phones got reception in any of the buildings on campus or in any most of the apartment complexes, and signal strength in open air was limited to one or two bars at best.
