Metrico Wireless Sets the Record Straight on AT&T iPhone Vs. Verizon iPhone Performance

[Metrico Wireless releases report comparing the Verizon Wireless and AT&T's version of the iPhone 4.]

Frederick, Md -- Metrico Wireless Inc., a leading provider of mobile device performance information and solutions, just unveiled one of the most comprehensive evaluations yet of the end user experience offered by the Verizon Wireless and AT&T Wireless versions of the iPhone 4.

How did they stack up? It depends on how the customer is using the device. For instance, the AT&T iPhone experienced double the mean data download speed of the Verizon iPhone, but the mean load time for an average Web page was about the same on both devices.

In addition, the findings showed that when the iPhone is mobile, the AT&T iPhone successfully completed around 10 percent more data download sessions than the Verizon iPhone. The results were opposite when the iPhones were stationary; the Verizon iPhone was more consistent uploading data when stationary in comparison to the AT&T iPhone, with a 10 percent better success rate.

The iPhone 4 is the latest of more than 80 smartphones evaluated to date as part of Metrico’s unique Smartphone Mobile Experience (M.E.) evaluation program.

“The mobile industry is competing on performance, and anecdotal performance information isn’t good enough to drive management and marketing decisions,” said Richard McNally, VP, Information Products, Metrico Wireless. “Metrico’s Smartphone M.E. program provides carriers and OEMs with an information resource that establishes an objective and scientifically derived user-experience performance baseline.”

A comparative look at the performance of the iPhone on both networks can be found in Metrico’s latest Smartphone M.E. Special Insights Report, “iPhone vs. iPhone: Illuminating the Debate with Data - Not Opinion,” at

As part of Metrico’s Smartphone M.E. program, Metrico compared the AT&T iPhone to 22 other AT&T smartphones. When compared to other AT&T smartphones:

* The AT&T iPhone ranks near the top on data download and upload speed, with comparable performance to the Sony Ericsson Xperia, the LG Quantum and the HTC Surround. * The AT&T iPhone ranks below average in Bluetooth speech quality behind top rated performers like the Blackberry Torch and Blackberry Curve. * The AT&T iPhone ranks in the middle of the pack on call performance behind top rated performers like the Samsung Captivate and the HTC Aria.

When compared to 17 other Verizon smartphones:

* The Verizon iPhone ranks near the top in noise canceling performance, joining the likes of the Motorola Droid X and the LG Ally. * The iPhone ranks below average in data download speed relative to other Verizon smartphones like the HTC Incredible. * The iPhone is comparable to the Verizon average in speech quality, behind top performers like the LG Fathom.

In the special report, Metrico measures data download speed, Web browsing, call performance and voice quality on both live and simulated mobile networks to obtain statistically valid metrics on the real-world performance of both versions of the iPhone. To collect performance evaluation data for the report, Metrico performed over 10,000 Web page downloads, ran more than 2,000 data download/upload tests and made nearly 4,000 voice calls.

How Metrico’s Smartphone M.E. Program Works

Metrico developed the iPhone M.E. Special Insights Report as part of its Smartphone M.E. program, which evaluates the performance of all commercially available smartphones sold by Tier 1 U.S. carriers. The subscription-based service gives mobile industry players – including carriers, OEMs and enterprises – vital comparison data on the call performance, voice quality, and Web and data performance of more than 90 smartphones annually.

This data is easily accessible to M.E. subscribers via Metrico’s proprietary M.E. database – the largest collection of smartphone performance data available today. Mobile operators and manufacturers can use the M.E. data to gain competitive insights, verify post-launch performance or to more effectively promote a brand. Enterprise IT directors can use M.E. reports to determine which devices to purchase and which carrier they should choose to support particular devices.

Metrico is showcasing its Smartphone M.E. and its Fit4Launch performance evaluation programs at CTIA Wireless 2011 on March 22-24 in Orlando, Fla., in Metrico’s booth #4780.
