Editors' note: If you've already read "Battle Royale: Five smartphones face off", "Battle Royale 2: Smartphones face off, screen to screen", or "Battle Royale 3: The Final Conflict" (which, you know, didn't really pan out given the article you're currently reading), then you may experience some deja vu when reading this article. We've used the same tests and presented the article in the same style. Only the phones in question and the details of their performance have changed. Because of some technical difficulties on the back end, our "How we test: Smartphone displays" page (still!!) isn't up yet, but hopefully by Round 5 it will be.
I've now tested 12 different smartphone displays, including the two new ones presented today. Android and iPhone fans remain as passionate as ever about seemingly every aspect of their favorite phones, but now a new fighter enters the tournament. Today we test our first Windows Phone 7...um, phone. (I still have an aversion to the OS name.)
Once again, using DisplayMate Multimedia Edition for Mobile Displays, I put each phone through a battery of tests.
Well, today is a new day, and with that comes the promise of a more robust evaluation (or so the saying goes). For Round 4, not only do we have the iPhone 4, but also the Samsung Nexus S.
As in previous roundups, we used three different types of tests to evaluate each phone:
Scientific measurements: We used the Konica Minolta CS-200 ChromaMeter to test the maximum brightness, black level, and contrast ratio of each phone and reported numbers for each of these three tests.
Test pattern screens: We used several DisplayMate Mobile test patterns to test for color-tracking errors, 24-bit color, and font legibility, among other things.
Real-world: We conducted real-world anecdotal testing using photos and 3D games.
All test screens were viewed within each phone's native gallery application. Some phones may handle pictures differently--and even improve them to some extent--outside the gallery application. That said, we believe that testing within the respective gallery applications is still a viable approach, as this is where most users will view pictures on their phones.
In order to diminish potential repetition, I'll dive right into the details of how each phone performed; if you'd like to know more about our tests, you can binge on nerdy details in our "How we tested" section at the bottom of this article. Please note that this is an evaluation of each phone's screen performance and nothing else. Check out the full reviews of these phones to determine which is right for you. Also, DisplayMate has posted a more technically focused evaluation of the iPhone 4 screens that's worth checking out.
