Form Factor

Samsung Galaxy S II – 125.3 x 66.1 x 8.5 mm
iPhone 4S – 115.2 x 58.6 x 9.3 mm

In comparing phones, most of the users check out the make of the mobile phone and its weight is what that matters. Galaxy S II has the dimension of 125.3 x 66.1 x 8.5 mm with a weight of 116 grams and Apple iPhone 4S has the dimensions of 115.2 x 58.6 x 9.3 mm with a weight of 140 grams.


Samsung Galaxy S II – Dual Core 1.2 or 1.5 Ghz processor
iPhone 4S – A5 dual core processor

The Samsung Galaxy S II phones has Exynos 4210 SoC processor clocked at a frequency of1.2 Ghz Cortex A9 dual core processor with GPU acceleration that is supported by ARM Mali 400 MP. The iPhone 4S is powered with A5 SoC consisting of Cortex A9 dual core processor and a powerful PowerVR SGX543MP2 GPU.

The iPhone 4S has not specified the frequency of its dual core processor hence it would be absurd in comparing it so early until its launch. But considering Samsung Galaxy S II phone the processor is much faster providing an amazing experience. On the other hand the iPhone 4S wins the battle in graphical acceleration.

Operating System

Samsung Galaxy S II – Google Android 2.3 Gingerbread
iPhone 4S – iOS 5 operating system

The main deviation comes in the operating system provided by both the phones. While Android is flying high and Samsung doesn’t leave the Galaxy Series handset, the Galaxy S II phone with TouchWIZ 4.0 has broken the records and it’s the best Android mobile phone to possess. Android OS is liked by everyone because of its open source and easy customization. It’s pretty straight comparison, the iPhone 4S locks you with iOS 5 which is completely revamped with message notifications, new camera app and other changes. The Android 2.3 looks stale when compared to iOS 5 . However a clear-cut comparison between the best operating system depends on the preference of the users whether to go for open source or be with iOS.

Display Screen

Samsung Galaxy S II – 4.3 inches Super AMOLED Plus display
iPhone 4S – 3.5 inches IPS LCD display

The Galaxy S II phone has WVGA 4.3 inches Super AMOLED Plus capacitive touchscreen display with a maximum resolution of 800 x 480 pixels while its competitor iPhone 4S has 3.5 inches IPS LCD touchscreen display with 640 x 960 pixels resolution. The iPhone 4S beats the Galaxy S II phone in terms of pixels and resolution but Galaxy S II emerges as the winner  with 4.3 inches large screen and amazing SuperAMOLED display providing higher colors and contrast ratio.


Samsung Galaxy S II – 8 mega pixel rear and 2 MP front facing
iPhone 4S – 8 mega pixel rear and basic VGA camera on front

Both Apple iPhone 4S and Galaxy S II phone comes with 8 mega pixel rear camera with LED flash. The major difference occurs with the front camera where Galaxy S II leads with 2 mega pixel camera as that of VGA camera on iPhone. This in turn doesn’t mean that iPhone camera is unsuitable, not to forget that iPhone 4S has a custom ISP design which has the feature like Face recognition using Facetime, Hybrid IR filter and auto white balance.

Galaxy S II camera Apple iPhone 4S

Both the phones are able to record HD video at 1080p at a resolution of 30fps but iPhone records much better videos than its competitor. In turn, it doesn’t mean that Galaxy S II camera is crap; it has one of the best cameras among  all the Android handsets in the market.

Winner : iPhone 4S


When it comes to Apple they always go for fixed memory which determines its price. iPhone 4S is available in 16 GB, 32 GB & 64 GB models with no external storage. On the other hand, Galaxy S II provides 16 GB of internal memory and it can be expanded further up to 32 GB in size using the microSD card slot.

Network & Speed

Accordingly the specifications Galaxy S II clearly emerges as the winner as it has 4G WiMax capabilities. Along with that the HSPA+ connectivity provides you a top speed of 21 Mbps. You would be disappointed if  iPhone 4S is just providing 3G HSPA speed of 14.4 Mbps only.


The iPhone 4S has a dedicated camera button, which is absent in Galaxy S2. However, Galaxy S2 comes with rechargeable battery where iPhone 4S doesn’t and it is also clear that iPhone 4S weights 0.6 oz higher than its competitor.


Though battery life is not an important issue to talk about, we just thought of providing you a brief insight of phone batteries.With 1650 mAh battery on Galaxy S II, it can provide you 8 hours of talk time and same could be found on iPhone 4S with undisclosed battery specifications.

The above picture clearly shows the battery of Galaxy S II phone.

Winner: Samsung Galaxy S II


No matter how good your phone is, pricing is what matters finally. Samsung Galaxy S2 is sold from $ 199 to $ 229 in contract with US carriers and unlocked device is priced at over $ 600. The iPhone 4S continues its trends and is available in various storage options, 16 GB at $ 199, 32 GB at $ 299, 64 GB priced at $ 399.

The Verdict

This is for the first time that a product from Apple has faced its downfall compared to any other phone at its launch. The iPhone 4S goes with a small screen compared to other handsets in the market though its evolutionary hardware is a hit. Moreover, iPhone 4S compared with its predecessor models, looks just the same but hardware is evolved. One would be thinking what Apple was cooking out at the back for 14 months since the inception of iPhone 4 but statistics speaks, iPhone 4S creates history by booking 0.6 million on its release day.

So who is the ultimate winner? It would be quite unfair to say iPhone 4S is not good smartphone as the craze for Apple products is still on high. People still get attracted to Galaxy S II as it has a greater advantage  of possessing the best Android operating system. Though I feel that Galaxy S2 has slighter advantage, I would like to leave this decision to our Android Advices readers.

Update – Its quite interesting to read users comments here in this article. There are many Apple fan followers comments.


  1. Magnificent goods from you, man. I have keep in mind your stuff prior to and you are just too fantastic. I really like what you have acquired here, really like what you’re saying and the way during which you are saying it. You’re making it entertaining and you still care for to keep it smart. I can not wait to learn much more from you. This is actually a wonderful website.

  2. SII is the banned phone as copying the features of APPLE.

    Apple 4S battery talk time is 8 hours on 3g and 14 hours on 2g
    but in samsung Talk time*: up to 20 Hr (2G), 10 Hr (3G) is normally 15 hrs and 7 hours in usage.

    The Music Player in iOS an outstanding GUI.
    In terms of OS iOS is the world most advanced operating system.

    Safari the advanced web browser for the mobile platforms. which is lags in ANDROID.


  3. The Samsung is the winner. I have an android smartphone (xperia s)  and an iPhone 4S. I prefer android. iPhone is very good when jailbroken (with iSwipe and SBSettings installed), otherwise it’s really outdated. Sending some attachments by mail is a true crime. I find Android much better than IOS5.with that annoying settings screen, in which you have to set everything… just give me a normal menu in each app, much faster)  Siri is a very nice feature on the iPhone, but often can’t give me the answer i’m searching for, or does not understand what i mean. So if i should recommend something, it will be Android. Android rulez over IOS5, so take the Samsung, it will be the best shot. 
    (Unless Apple comes with a really good update of IOS5 with Swipe, a normal menu and a “one touch auto killing apps”-app, and a better Siri… then i would doubt which to buy).

    But of course, doubt my opinion as you like, and buy what you want. It’s all a matter of taste. But i can’t understand the Apple madness, it’s probably the vitamins…. ;-)

    • People tend to compare to the best… Not a single proud owner of a Iphone will compare his smart phone to a Samsun smart phone. That’s why you see pages and pages people making opinions after opinions to reinsure them self and justify the money that spend on their smart phones. The fact is that Iphone is the leading smart phone and the rest are imitations or wanna beeeeeesssss…

  4. Iphone 4s is creating history i think that…galaxy s || is not worst but i truely say that iphone has many features then galaxy s||.and ios is bestest and android has many bugs… Wnene ios 6 will cone coz it has its own apple map
    Facebook integration…so i think that iphone 4s should be winner….


  6. Galaxy S2 is quite better than Iphone 4S


  8. Galaxy S2 is good but 4s is awesome in many specs

  9. I’m sorry, even with the comparison I still think the IPhone is better than the galaxy S2. I have the IPhone & my boyfriend has the galaxy & I am capable of doing a lot more with my phone than he can with his! True fact!
