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.

    Wow I wish I had first comment here so I could get a response.

    In Anand's otherwise near-perfect review, he talked about Exchange support but didn't cover my #1 iPhone question: does Exchange support work without the $45 Enterprise Data plan? I can't for the life of my get a conclusive answer if the Enterprise plan is required for exchange, or just required if the iPhone is going to be purchased or paid for through a business.

    i'm still holding out for the day the iphone comes with some real screen resolution.

    if the N810 can do much better than this, why can't the almighty apple?
  • sleepr0 - Friday, July 18, 2008 - link

    Lets see:

    - The 3G doesn't fit the old cradle and the cradle is not included - $15.
    - Old cover doesn't fit - $20.
    - Unlimited data up $10/month.
    - Text up $5/month.
    - Cellular triangulation works nearly as well as GPS.
    - 3G not significantly faster than Edge and all the new users will take a load off of the Edge network, freeing up bandwidth and making Edge a bit faster.
    - Battery life worse.

    I'll wait for Version 3, thanks.

    Why do you buy a new phone when you are happy with your old one – it has pretty much the same functionality anyway? What is wrong with all those people who buy something just because Apple (or whoever) releases it? All these morons queueing up, did they all accidentally happen to break their phone the day before?

    It's a nice in-depth article, no remarks there, I've just heard enough already about this consumer hype. It's just talking people into fake needs.

    Blast me for being negative, but you know I'm right.

    The problem is that people aren't happy with their old one, and it doesn't have the same functionality, so that is why they queue for the iPhone. So essentially all your base assumptions are wrong.

    There is nothing wrong with these people; there is something wrong with the RZRS et al they already own, because they were broken the minute they bought them. No accident, they were just made that way.

    No, actually you aren't right. You could be, if we were here to make free-philosophy, but that's not the case, we're here to talk about hardware (and related).

    So then, you are accusing the mass of an excess of "hype" around the iPhone, and well, while it's definitely true that many of those people will buy it for "trendy" purposes, there are surely others (like me) who are about to buy it because they just like it and could benefit from it. In my particular case, I have lost my iPod Mini (...) and my cellphone is at its 4th year of life, with the keyboard almost died (intense 20.000+ sms usage in these years). The iPhone, by simply being, to me, an iPod which calls and writes sms, is great to have both the devices in the "main" pocket.

    Full comfort over the whole year (no matter what clothes I'm wearing, the front/right pocket does ALWAYS have my cellphone inside, and thanks to the iPhone, the iPod as well), a brilliant keyboard for my heavy SMS usage, and I could be happy without anything else. Plus, there's something else actually, and I'll surely enjoy.

    If we had to think like you in your post, we should all tell you: Why do you read Anandtech? You can live with a 5 years old PC without problems nor upgrades, if you just use some Office, browse the web and check your mail. If you game, well, that's energy consuming, money-wasting, time-wasting, and you should quit. But, of course, none in here would say that to you, neither would I.

    Regards

    First, I've had AT&T for years. Never stepped in a store, and never talked with them about a purchase. They were very helpful and darn quick about replacing my wife's phone when it died. AT&T is the easiest to work with (and I work with most of them because I support a lot of folks on different networks) Plus, the AT&T signal in the places I go beats out all others hands down. So for you to say their signal is bad is very objective and quite stupid, since you did it only probably in one room and not overall.

    Also, your indications that other phones can't do what the iPhone can do are all false. One thing the iPhone CAN'T do that many many other phones can do is change. It can't change it's interface to suit other purposes, it can't change it's battery, and it can't change carriers. The 3G's only add over the old iPhone is 3G and GPS. All other features are software, and now available on the original iPhone. So an upgrade is useless until you contract is up.

    Apple is a closed box. I prefer freedom.

    Uh, with a soft interface and touchscreen, the iPhone is just about the only device where it's interface can change as needed; you get two buttons when in Camera mode, 20+ in Calculator mode, 26+ in note-taking mode, etc.

    I will buy at lunch. I read alot of reviews over the web including sites that dedicate themselves to phones. I found this to be one that i could relate to. Thanks.

    My younger brother works for Garmin. You almost certainly won't get voice directions, at least not for free. The licensing agreements with the few companies that make the maps used in mapping software (e.g. Navteq) are very specific about what you can and can't do with the maps they provide. The mapping companies currently charge significantly more if you want to do voice directions. Nokia's purchase of Navteq makes a huge lot of sense given what one can do with maps, a GPS, and Internet all in one package. All of this is probably part of the reason that Garmin is getting into the phone business with the nuvifone.
