While we’re still working on the full review, I want to get out some preliminary results for the iPhone 6. For now, this means some basic performance data and battery life, which include browser benchmarks, game-type benchmarks, and our standard web browsing battery life test. There’s definitely a lot more to talk about for this phone, but this should give an idea of what to expect in the full review. To start, we'll look at the browser benchmarks, which can serve as a relatively useful proxy for CPU performance.

SunSpider 1.0.2 Benchmark  (Chrome/Safari/IE)

Kraken 1.1 (Chrome/Safari/IE)

Google Octane v2  (Chrome/Safari/IE)

WebXPRT (Chrome/Safari/IE)

There are a few interesting observations here, as a great deal of the scaling is above what one would expect from the minor frequency bump when comparing A7 and A8. In SunSpider, we see about a 13% increase in performance that can't be explained by frequency increases alone. For Kraken, this change is around 7.5%, and we see a similar trend across the board for the rest of these tests. This points towards a relatively similar underlying architecture, although it's still too early to tell how much changes between the A7 and A8 CPU architectures. Next, we'll look at GPU performance in 3DMark and GFXBench, although we're still working on figuring out the exact GPU in A8.

3DMark 1.2 Unlimited - Overall

3DMark 1.2 Unlimited - Graphics

3DMark 1.2 Unlimited - Physics

GFXBench 3.0 Manhattan (Onscreen)

GFXBench 3.0 Manhattan (Offscreen)

GFXBench 3.0 T-Rex HD (Onscreen)

GFXBench 3.0 T-Rex HD (Offscreen)

In in GPU benchmarks, we generally see a pretty solid lead over the competition for the iPhone 6/A8. It's seems quite clear that there is a significant impact to GPU performance in the iPhone 6 Plus due to the 2208x1242 resolution that all content is rendered at. It seems that this is necessary though, as the rendering system for iOS cannot easily adapt to arbitrary resolutions and display sizes. Before we wrap up this article though, I definitely need to address battery life. As with all of our battery life tests, we standardize on 200 nits and ensure that our workload in the web browsing test has a reasonable amount of time in all power states of an SoC.

Web Browsing Battery Life (WiFi)

As one can see, it seems that Apple has managed to do something quite incredible with battery life. Normally an 1810 mAh battery with 3.82V nominal voltage would be quite a poor performer, but the iPhone 6 is a step above just about every other Android smartphone on the market. The iPhone 6 Plus also has a strong showing, although not quite delivering outrageous levels of battery life the way the Ascend Mate 2 does. That's it for now, but the full review should be coming in the near future.

    Battery Life Iphone 6 in 3G / 4G network is only 1 hour more compared to the iPhone 5s

    Do not expect more than that.

    279 comments for the preliminary results. I wonder how many will be for the final review!!
    Anand, when is gonna be the final review then? :)

    I have a problem with the Battery test.
    I own an iPhone 5 and i love it, but the battery is shit, I cant belive that this device does better than iPhone 5S 5C and Galaxy S5.And how come the MOTO G CAME ALMOST ON TOP, this phone has mediocre battery.

    This is interesting why many other sites write about poor battery life and you say otherwise.
    Sorry, but there isn't any tech out there that allows good battery life from a 1810 mAh battery, period. Maybe just take the phone and test it in real life for a few days.

    Battery life is good on my iPhone 6. Don't really care about all these random tests coming out - in the "real world" this is what I get - http://i940.photobucket.com/albums/ad245/Jimrod/BF... Reply
