What's behind our cell phone & service Ratings?

Experts at our National Testing and Research Center tested 36 models in cell phones & services to see which ones perform best.
We look for:
  • Overall score
    Overall score is based mainly on Ease of use, Messaging, Web browsing, Display quality, Voice quality, Phoning, Battery life, Camera Image and Video quality, and Portability. Music, camera, and other features and capabilities are also considered. For those available from multiple providers, test results are averaged. The displayed score is out of a total of 100 points. Phones are listed in performance order. Due to test upgrades, and phone firmware updates, results may vary from past Ratings.
  • Ease of use
    Ease of use mainly considers how easy is it is to access the phone's various features and modes, such as phoning, messaging, Web browsing, the camera, the music player, applications and other multimedia content. We also consider one-­handed operation, programmable shortcuts and touch screens.
  • Messaging
    Messaging mainly assesses keyboard ergonomics, e-mail readability, attachment capabilities, and text­-messaging features. It also considers display size and corporate capabilities.
  • Web browsing
    Web browsing mainly assesses browser capabilities, including the phone's ability to handle more than one browser, display size, processor, and data connections, such as 3G, 4G, and Wi­Fi.
  • Display quality
    Display quality represents overall picture quality, which includes pixel resolution, contrast in normal and bright lighting (outdoor use), and color accuracy.
  • Voice quality
    Voice quality considers listening quality which reflects what you hear; talking, what's heard by other phones. Tests were conducted in noisy and quiet environments using live conventional phone calls indicated by carrier used.
  • Phoning
    Phoning considers the step-saving functions for making and receiving calls. These include hands-free capabilities such as voice command and Bluetooth, one-­handed operation, speed dialing, ringer controls, call timers, and other features. We also evaluated keypad readability under different lighting conditions, and holding a phone while on a call.
  • Battery life
    Battery life represents tests under nominal cell-network signals, including battery consumption performing tasks that involve voice, data, display, and other factors.
  • Camera: Image quality
    Image quality is based on objective and subjective judgments of test images, which includes evaluating resolution, dynamic range, color accuracy, and visual noise.
  • Camera: Video quality
    Video quality is based on the judgments of trained panelists who viewed recorded video images shot at the highest quality setting available (1080p max.) in multiple lighting conditions.
  • Portability
    Portability represents our judgment based on the best combination of size and weight.
  • Water resistance test
    Test result at claimed depth and time duration. NA - not applicable.
  • AT&T
    Provider availability.
  • Sprint
    Provider availability.
  • T-Mobile
    Provider availability.
  • Verizon
    Provider availability.
  • Unlocked
    These models, purchased unlocked, should work on major providers such as AT&T and T-Mobile. Check with your provider for potential service limitations.
  • Display diagonal size
    Display diagonal size is the diagonal length of main display measured to the nearest tenth of an inch. Some folding models have an additional, external display for viewing the time, music tracks, and other functions.
  • Display resolution
    Indicates the manufacturer stated number of pixels that the screen can display, in portrait orientation.
  • Operating system
    Operating system indicates the smartphone's operating system. See "Buying Guide" for more information about the operating systems.

Cell phone & service buying guide

Smartphones are finally getting smarter about serving the people who actually use them. Us. If you're in the market for a new model, you can expect a larger, sharper display that's easier to read; better performance; and, perhaps for the first time, a battery you can lean on for a full day before needing a re-charge. Smartphone cameras are improving too. Most have sensors with at least 8 megapixels and allow you to shoot high-definition videos. If camera performance ranks high on your list of criteria, look for models that earned scores of very good or better for image quality and good or better for video. Phone-display resolutions are increasing, as well. So-called Quad HD displays offer very high pixel densities (often more than 500 pixels per inch). That should mean sharper pictures and more detail. But in our tests, we found that most users won't notice the benefits in everyday use of Quad HD--partly because even the largest phones have relatively small displays. You will notice a difference, however--and not in a good way--if you buy a phone with a display that isn't at least HD. Stick with resolutions of 720p and higher. (If the resolution is expressed in pixel density, you want 300 ppi or higher.) Most handsets we tested have displays in the 4.5- to 6-inch range. The larger screens are great for viewing Web pages, maps, and videos, but the phones may be hard to manipulate. If you're considering one of these so-called phablets, make sure you can use it comfortably with one hand.
