iPhone 4S vs iPhone 4 Speed Test Comparison

Oct 14, 2011 - 5 Comments

We already know the iPhone 4S is significantly faster than the iPhone 4 just by looking at the tech specs, but sometimes the best way to see a speed boost is in real world activities like launching apps, browsing the web, and just tapping around in general.

This video shows the two devices side by side doing just that. Everything is quicker, but what really surprised me was how much faster websites load in Safari on the 4S, they appear almost instantaneously.

This reminds me a lot of when the iPhone 3GS came out, and users of the iPhone 3G felt like they had a fast phone… until they saw and used the 3GS, which then became the must-have upgrade. Very tempting upgrade for those who want the quickest iPhone out there.

Update: More videos below, here are 3G speed tests on AT&T with iPhone 4S vs iPhone 4, as well as more wi-fi tests. The 4S is much faster in both cases:

    I’ll say this here, too: Just not worth spending 1000-1500 of my currency for this, while selling my <1 year old perfect condition iPhone 4 for like 600-700.

    Well, I’ll upgrade in a month when I renew my contract. Might as well… my iPhone 4 is selling for like $350 on eBay. It’s basically a free upgrade to the 4S.

    I also don’t think the speed is that much different, but it looks better. For me, it’s not different enough to upgrade, but I also have to pay the full $550 from AT&T because of the contract, if it were not that, I would upgrade because I like to have the latest and greatest gadgets.

    :D :D :D

    Honestly, I thought the 4GS would be much faster than the 4. The speed difference seems only marginal.

    The iPhone 3G to 3GS and 3GS to 4 seemed like much more significant speed increases. I personally went from iPhone 3G to 4 and it was mind blowing! LOL
