Face Off: Samsung Captivate vs. Samsung Vibrant

  • MORE

We've recently settled some pretty tough smart phone battles, but nothing is more intense than a good ole' case of sibling rivalry. We're talking about the recently launch Samsung Captivate (AT&T) and Samsung Vibrant (T-Mobile), the first two members out the gate in the Galaxy S line. Both Android superphones sport Samsung's snappy dazzling Super AMOLED 4-inch displays, 1-GHz Hummingbird processors, and a robuts 16GB of storage. Samsung’s custom Touchwiz 3.0 interface on top of Android 2.1 (Eclair) graces each device, and they both can shoot 720p video.

So, yes, the Captivate and Vibrant are twins, but they're far from identical. And not just because one is sold by AT&T and the other by T-Mobile. Here's how these two powerhouses stack up.


Both the Captivate and Vibrant house the same 4-inch Super AMOLED high-res (800 x 480) display that’s simply a sight to behold.  Movies, pictures, video games-they all look glorious on either device. In almost every other way, though, these phones look quite different.

While dimensionally the same at 4.8 x 2.5 x 0.4 inches, the dark gray sides of the Captivate don’t look as sexy next to the chrome-like border of the iPhone 3G-inspired Vibrant; we prefer its more rounded corners.  They both have touch-sensitive capacitive buttons (Menu, Home, Back, and Search), but the space between the bottom of the display and the bottom edge of each phone (where the buttons are housed) is wider on the Vibrant, making them more comfortable to touch.  We found ourselves touching the bottom edge of the phone on the Captivate more than we liked.  The same buttons are also brighter on the Vibrant, making them easier to see in all lighting conditions.

On the other hand, we prefer the metal backplate of the Captivate over the glossy, more slippery plastic one of the Vibrant.  The sliding hinge on the Captivate also makes it much more user friendly to access the battery over the small slot (beneath the phone) used to pry open the Vibrant. At times we feared we might damage the case if we applied to much pressure.  The volume rocker on the Captivate is more contoured than the flat one on the Vibrant, making it easier to adjust, and the power/lock key on the Captivate is also larger and easier to press.

Winner: Draw. Both phones are svelte and pocket friendly. The sturdier metal backplate, and user-friendly opening mechanism on the Captivate balances with the brighter, more spacious capacitive buttons on the rounder Vibrant.

Specs and Performance

Under the hood, the Captivate and Vibrant have identical guts, including Samsung’s 1-GHz Hummingbird processor and 512MB of RAM, so it’s no surprise that they earned comparable scores during our four main Android benchmark tests.  They were all but dead even with the exception of Memory and Filesystem in the Benchmarking round.  The lower score on the Vibrant could be a side-effect of having a higher number of pre-installed applications.

Everyday use was basically the same with both phones.  For the most part, the Captivate and Vibrant ran Android 2.1 pretty smoothly. However, we did notice some slow down on both devices when opening apps or swiping between screens.  Unlocking the phone and launching the camera was fast on both devices, although the camera itself performed slower on the Vibrant (more on that later).

In terms of memory, the Captivate and Vibrant both have a generous 16GB of storage, but the Vibrant ships with an extra 2GB microSD card while the Captivate packs no extras. We believe the additional memory for the Vibrant makes up for the bundled Avatar: The Movie, a 1.8GB file preinstalled on the device.

Winner: Draw. Both phones are fast performers with identical innards, and their performance numbers place them on even ground.

Included Apps/Services

Both the Captivate and Vibrant operate on Android 2.1 (Éclair) overlaid with Samsung’s Touchwiz 3.0 interface and are nearly identical.  TouchWiz is to the Captivate and Vibrant as Sense is to the HTC Evo 4G, and brings a number of additions to Éclair like 7 home screens (over stock Éclair’s 5 home screens), plus an assortment of useful apps and widgets.

The Vibrant is loaded with more applications than the Captivate, but less bloatware.  T-Mobile nailed down exclusives like Avatar: The Movie and The Sims 3 by EA Games -- free premium items you’re less likely to uninstall (although they can be removed). Plus, there are applications like Audio Postcard, exclusively for T-Mobile Android phones. The premium paid TelNav GPS and GoGo (an in-flight Wi-Fi application) are the only apps we would categorize as bloatware.

There are other pre-installed apps on the Vibrant, including Kindle, Layar, Slacker, and ThinkFree Office- but these are not exclusives, and can be downloaded to the Captivate as well from the Android Market, or removed from the Vibrant altogether.  We do like that the Vibrant has Amazon MP3 for the default music store, rather than the clunky, often slow AT&T Music app that plagues the Captivate.  We recommend Captivate users to download the Amazon MP3 app from the Android Market.

The Captivate suffers from the same problem of too many mapping/location applications that occupy AT&T’s other Android device, The HTC Aria.  In addition to the extremely useful and free Google Maps Navigation, there is AT&T Family Map, AT&T Maps, AT&T Navigator, and YP Mobile.  Most of these apps have features that overlap one another.  Premium paid services like AT&T Radio seems unnecessary when there are free options like Pandora and Slacker (both available in the Android Market).

However, we do like the Instant Messaging app that easily connects you to AOL IM, MSN Messenger, and Yahoo Messenger--these have to be separately installed from the Android Market on the Vibrant.  Other pre-installed apps include Where and Mobile Banking, which can be installed on the Vibrant as well.

AT&T restricts sideloading on the Captivate, so apps and games (EA games in particular) not in the Android Market won't work unless you root the device. T-Mobile does not impose this restriction on the Vibrant.

Winner: Vibrant. The Captivate lacks any exciting exclusives like the entertainment applications on the Vibrant.  The Captivate also has way too many mapping applications, and you can't sideload apps.

Web Browsing

Both T-Mobile and AT&T have been constantly working on the expansion of their 3G networks, so we put the Captivate and Vibrant against one another in a browser battle to determine which device performs better.  While AT&T may have a larger 3G footprint over T-Mobile, the numbers tell a different story, see for yourself.

Web Test Results (seconds)












When we performed our side-by-side tests in our office, outside in Times Square NYC, and on a moving 45 minute bus commute, the Vibrant outpaced the Captivate every single time.  The Vibrant downloaded ESPN.com in an average of 7 seconds compared to the 9 seconds on the Captivate.  Yahoo.com loaded in 6 seconds compared to the Captivate’s 10 seconds, and our own Laptopmag.com site loaded in 19 seconds to the Captivate’s 25 seconds.

On average, the Vibrant was 29 percent faster than the Captivate. The Vibrant is not an HSPA+ device, but it does take of the network's enhanced speeds where available.

Winner: Vibrant. The Vibrant outpaced the Captivate in each test.


Both the Captivate and Vibrant have the same 5-Megapixel sensor, but in our test, they performed different.  Shot-to-shot, both phones had very similar shutter speeds. Each device captured quality images, but the photos taken with the Vibrant appear to have slightly warmer colors outdoors.

Indoors was more of the same;  theVibrant's  images were warmer.  The flowers and fruit snapped by the Captivate, however, appear slightly sharper and have more of a natural tone.

The Captivate and Vibrant were pretty much neck and neck when we captured some 720p footage.  The only difference we noticed again was that the Vibrant’s colors were slightly warmer.

Winner: Draw. The Vibrant produced warmer colors in all scenarios,  but the Captivate captured sharper images with more natural colors indoors.  Video quality was nearly neck and neck.

Battery Life

Both phones have a 1500mAh Li-on battery, and T-Mobile claims the Vibrant has a talk time rating up to 6.5 hours with 18 days standby time, while AT&T says the Captivate has up to 5 hours 50 minutes of talk time and 14 days standby time.

In our battery test, which uses the browser to surf 60 popular websites per minute over 3G until the battery dies, the Vibrant lasted 4 hours and 26 minutes.  The Captivate only endured 3 hours and 42 minutes, 44 minutes less than the Vibrant.  We are currently in the process of running the battery tests again.

Winner: Vibrant. So far the Vibrant outpaces the Captivate, but we'll be updating our results once we've run our test again.

Call Quality

The 0.5-inch earpiece on both the Captivate and Vibrant produced good volume and calls were relatively clear that we received from mobile and land lines.  The microphone, located under the bottom bezel on both phones, produced clear voice quality, and background noise was kept to a minimum from a voice message we left as we walked through a busy shopping mall.

Winner: Draw. With the same diameter earpiece and microphone position, both phones produced clear calls of the same quality.


Both the Captivate and Vibrant share the same accessories, including a Battery Charger with Stand ($49.99), Silicone Gel Case ($29.99), and Bluetooth headset ($69.99). The Vibrant, however, comes with an extra battery cover in a Lavender color.

Winner: Draw.

Pricing & Value

For $80 per month, you’ll be up and running with the Vibrant on T-Mobile’s Even More 500 Talk+Text+Web plan with 500 voice minutes, unlimited data (T-Mobile will slow down your speed after 5GB of usage), unlimited mobile to mobile, and unlimited text messages. With the Captivate, AT&T’s $39.99 Nation 450 (with rollover minutes), nets you 450 anytime minutes, and unlimited mobile to mobile.  Add $20 for unlimited text, and another $25 for $2GB of data ($10 per 1GB after the data cap is reached). The total comes out to $85.

Winner: Vibrant. Not only will you spend $5 less per month, T-Mobile does not charge you should you go over its data cap, and you get more voice minutes.

Overall Winner: Vibrant

The Samsung Captivate and Vibrant are two amazing phones in their own right, not to mention the best Android offering on their respective carriers, but there can only be one winner.  In our 9 rounds of testing, the Vibrant and Captivate were tied neck and neck in 5 categories, but the Vibrant outpaced the Captivate in 4 crucial areas: Web browsing speed, battery life, pricing/value, and included apps.

The battery on the Vibrant lasted 44 minutes over the Captivate (we will re-run the test). Plus, T-Mobile bundles fun exclusives like Avatar: The Movie and EA's The Sims 3. We also like that you won't incur any surcharges should you go over T-Mobile's larger 5GB data cap (your download speed will decrease, however).

Overall, we like the Captivate for AT&T customers, but the Vibrant for T-Mobile is the better overall Galaxy S phone.

    In Canada, the Vibrant now has video calling where as the Captivate does not. That puts the Vibrant miles ahead in my books. The Catch-22 is that The Bell plan (Vibrant) is more expensive than The Rogers (Captivate) plan because I get free voice and call display with Rogers, saving me $12 a month. So really stuck here. Wish I could get the Vibrant on my Rogers plan. Ohhh the horror!!!

    Thanks Rod, that was a nice addition to the written comparison.

    Thank you Brian and Rod, you made my decision easy, I'm going for Captivate and hoping that I can unlock it to use t-mobile in case I want.

    Hey all,

    I have actually owned both of these phones. I started with the T mobile Vibrant a week ago. It is a very nice phone. As far as the review goes, I would agree with several points; however, I write to point out my observations and personal experience.

    The vibrant is a lot like holding an ipod touch in your hand. very thin, slick edge. The plastic back is not a good feel. There is a protrusion at the bottom which serves better as a side grip while using the phone horizontally rather than vertically. I found myself immediately wanting a gel case to add grip to the phone. The buttons at the bottom are definitely brighter when lit. Also the power and rocker buttons have insets that caused me to have to turn the phone sideways often to use them-not good. The phone does come with the 2GB card, the Sims game and other apps along with a movie that is really nice. The best part of this phone option was the phone plan with the carrier. I happily arrived home though to discover that there was no carrier signal for at least a half mile from my home. We tried switching sim cards with no improvement. Back went the vibrant.

    I learned who had a strong signal in my area from users THEN went shopping again. I knew that the phone plan would cost more but was not sure of what phone to get. ATT's iphone and the Sammy Captivate became the two finalists. Although I might be considered an Apple fanboy with two of their laptops and three desktop models AND a mobile me account, I still wanted to keep the phone choice a separate issue. The captivate won. I must say that although the reviewer likes the rounded corners, I find the more angular phone better to hold. I still want to get a gel cover but do not feel an urgency to do so. The metal back also has a rough texture and the back is smooth which I like better. The operating buttons power, volume rocker actually are above the flush surface point so they are much easier to use. I do wish the lighted buttons home, back, etc were bright like the vibrant though - they are dim lit when used in comparison. I am not familiar yet with the ATT apps. I really liked the software on the Vibrant but my phone geek friend tells me that most of those apps can be added anyway. As far as the phone itself goes, I prefer the captivate.

    One final point of both phones is the camera without flash issue. First, it is not an issue. Consider the weak LED flash of a camera. Most times, as with cameras, the flash illuminates objects about 10ft or so (3 ft with an LED) then the light quickly dissipates. These phones have night shot which, in my opinion is superior to a flash for general picture shots. There is a test of this at http://www.tmonews.com/2010/07/is-the-samsung-vibrant-night-mode-a-worthwhile-replacement-to-flash/

    Note how the 9:30pm shot of the field is completely lit, not just a 3 ft radius.

    Either of these phones make a good choice. I would have the vibrant now if I had a carrier signal at my home. As it is I pay more and have the captivate which is equally as good. Both phones are very lightweight and function packed. Oh, and yes I did look at the HTC phones - very well built but at the end of the current day, the Galaxy S phones pack newest tech - Bluetooth 3, WIFI N, fastest processor and GPU, etc. Hard to beat the light and fast!
