Galaxy S2 vs Galaxy S2 Skyrocket: One and the Same — Not

by: JoseNovember 11, 2011


The Samsung Galaxy line has been a name that many smartphone makers look up to. Two of the latest smartphones in the Galaxy line right now are the Galaxy S II and the Galaxy S II Skyrocket. Several people say that the only difference between the two is just the LTE connection support in the Skyrocket. Let’s go ahead and find out.

The looks

The size of these two smartphones is very similar. The Skyrocket is just slightly bigger by 0.5 mm than the Galaxy S2 and is also thicker by 0.1 mm. The Skyrocket has more curves at its edges compared to the S2, so it’s actually easier to hold.

The arrangement of the physical buttons is the same on these devices: volume rockers at the right side, power button on the left, Micro USB port for charging and syncing at the bottom, and the 3.5-mm headset jack at the top.

You will notice a tiny difference in the position of the camera flash at the back.  On the Galaxy S2, it sits beside the camera.  On the Skyrocket, it sits at the bottom of the camera.

The physical button at the bottom of the screen of the Galaxy S2 would be another noticeable difference since the Skyrocket only has the touch-screen ones.

Processor under the hood

Both devices use dual-core processors, which says much about what one can expect of the devices’ processing potentials.Though they differ in processor type and clock speed.  On the one hand, the Galaxy S2 uses the Samsung Exynos 4210 running at 1.2 GHz.  On the other hand, the Skyrocket uses a Qualcomm Snapdragron processor clocked at 1.5 GHz.  Both devices come with 1 GB of RAM each, to support their powerful processors.

To the ordinary person on the street, the processor type and clock speed on these two devices won’t mean much.  But, to those who are picky about specs and processing potential, the processor type and clock speed may matter much, even if the clock speed difference is only 0.3 GHz.

Operating system

The Galaxy S2 and the Skyrocket run Android 2.3 Gingerbread. There’s a very small difference though, since the Galaxy S2 uses the earlier Android 2.3.4 while the Skyrocket uses Android 2.3.5.  Though, most users don’t seem to mind the slight difference in versions.

These smartphones are also equipped with Samsung’s proprietary Touchwiz UI. This user interface has been known for its good looks and its very fluid animations. It comes with seven home screens which users can easily customize. Gingerbread may be not stay long inside these smartphones, since Samsung is planning an upgrade to Ice Cream Sandwich soon.

Display screen

The screen sizes of these devices are bigger than the typical smartphones. These two might not really be pocket-friendly devices. Both devices use the WVGA Super AMOLED Plus touchscreen display. To protect the display screen, Samsung uses tough Gorilla Glass with fingerprint-resistant coating.

As mentioned, screen size differs between the two. The Skyrocket sports a bigger 4.5-inch screen, while the Galaxy S2 has a 4.3-inch screen. This also explains why the Skyrocket is bigger in size.


Both the Galaxy S2 and Skyrocket sport two digital cameras. The one at the front is a 2-megapixel shooter which enables users to video chat with ease. The back-facing camera is an 8-megapixel shooter paired with a LED flash. The camera at the back doesn’t just capture high resolution pictures but can also record 1080p HD videos.

Storage capacity

Storage is a major concern when it comes to our mobile devices. Samsung made sure that the Galaxy line won’t have any issues with this. The Galaxy S2 has two variants, a 16 GB model and a 32 GB model. The Skyrocket on the other hand has 16 GB of internal storage. Both devices have a microSD card slots, which can support up to 32 GB of additional storage.

Wireless connectivity

These devices are packed with the right communications hardware, after all what’s a smartphone if you can’t communicate.  Bluetooth 3.0 makes it possible for these devices to connect accessories like a wireless headset or a wireless keyboard. This also enables file sharing between devices.  Wi-Fi enables these smartphones to connect to the Web if network data connection is not available.

One of the major differences between the Galaxy S2 and the Skyrocket is LTE network support. The Galaxy S2 can only support 3G HSDPA connectivity, which is the older and slower standard. The Skyrocket, in contrast, supports 4G LTE connectivity, which translates to a faster data connection.

Battery life

The battery life of a phone is an integral factor performance-wise. The devices being compared have different batteries. The Galaxy S2 runs on a 1,650-mAh Li-ion battery while the Skyrocket has a 1,850-mAh Li-ion one. This clearly indicates that the battery in the Skyrocket has higher capacity; though, this won’t mean that it will last longer than the other. The LTE connectivity may require more juice than the usual.

Samsung Galaxy S2


Both smartphones are under the AT&T network. The Galaxy S II is available for US$199.99 with a two-year contract. The Skyrocket, on the other hand, has a price tag of US$249.99 with a two-year contract.


It’s not just LTE connectivity that sets the two devices apart. The battery capacity is another major one besides LTE. The form factor is another thing. The bigger display and size of the Skyrocket may not be appealing to some, but for others, an additional 0.5 mm won’t matter.

As for LTE connectivity, for now this might just be in select areas in the U.S., but this will be the future of data connections. The question is, are you ready to jump to the future?

    what is the sim-free price?

  • Nateysmith

    The physical buttons are not different on the ATT Galaxy S II. This was a European version of the GSII that was being shown in all the pictures.

    You have the processor on the SkyRocket wrong. It is a snapdragon not a exynos. The Shiite processor is a better CPU and gpu

      re-read the article, mr dyslexic

  • Nicholas Berry

    wow huge fail on the article. Lrn2report

    You are wrong about the skyrocket’s processor, it has an different chip (the inferior snapdragon). Maybe you should learn a thing or two about phones before reviewing them?

    • …yes snapdragon is not as powerful as exynos but the extra .3 GHz helps make up for it.

      • The snapdragon is a proven chip but has a tendency to overheat. I think the overall comparison is a wash for this reason. There are no noticeable differences with actual use on the devices I’ve seen so far. Unless the satisfaction of a quadrant number is THAT important to you, I suggest looking at the critical issues – battery life is good on both but the Skyrocket gets hot. Not enough to worry but it makes your average user uneasy (although, those people should just have iPhones and leave the cool devices to people who care). The LTE is an obvious reason to fork out the measly $50. It would be retarded not to get the Skyrocket.

    I was told this phone does not have Gorilla glass by a Samsung representative.

  • aa

    Pretty awful article…

  • Nclsbeltran

    quarkgluonsoup, dude get over the bullshit processor topic. I own
    A SGS Skyrocket and I have no complaints over the processor. I memean it loads webpages instantly. 300 MB bids it downloads in 2 min!!! Can you say that about the gs2?? No I do.t think buddy.

    Well that was a little awkward

    I am looking to replace my Iphone with either the Skyrocket or Galaxy SII. any comments on which one is better from your experience?

  • TurtleJack

    I liked the article although I am not sure of the critics validity below. They may have a point but I am not sure I care at this… point. I have just recently acquired the LTE version and because I have been looking for accessories (nightmare!) I know of an other added difference that is much more significant that you may think. The audio jack is slightly to the left of middle whereas on the other (i9100?) it’s to the right which makes it VERY difficult to find cases, docks & skins. (in addition to the camera configuration).

    I went to 10 different stores/kiosks searching for something cool… and this is a small mall! Finally found a half decent one that I liked (selection sucks for both right now in Canada) and that is when I realized these phones differ… it didn’t fit.

    Trying to find things online but because most sites are American they use different terminology… they call them by their provider’s names. AT&T, T-Mobile, Sprint or their numbers (SGH-1777, SGH-1727, SGH-T989 and the only one I recognize because it’s with Bell… the i9100) so I have no idea what fits my phone!

    I reeeeeally feel they should have changed the name completely or just left the buttons alone to help us find these freakin’ accessories.

    I actually appreciated this article because it’s a start in knowing others may be having the same difficulty as me. Misery loves company!

    If anyone can enlighten me further it’d be appreciated!

    I just bought the skyrocket. This is my first smartphone.

  • Csuebgirl

    Hi. Do you mean 0.5 cm (5mm) and .1 cm (1 mm). A difference of 0.5 is not noticeable if you’re referring to the screen size difference.

  • tiffany

    It clearly states it has snapdragon in it go reread the description

  • joseph

    This phone is badass Sgh i727 skyrocket

  • susan
