Review: T-Mobile myTouch 3G
Screen
The myTouch 3G has a large capacitive touch display. It looks great. It is bright, colorful, sharp and byoo-tee-ful. I found it was easy to see and read when outdoors, though users may have to futz with the settings a bit. Mostly sunny skies weren't too much of a problem, but direct sunlight made apps such as Gmail a little difficult to discern. On the whole, though, there's not a lot to gripe about. It's a good display.
Signal
I didn't have too many problems with the myTouch with respect to signal. T-Mobile coverage is pretty good where I live, and most of the metro NYC area is covered with T-Mobile's 3G. In the phone, the myTouch showed only two bars in most places I took it. Other T-Mobile phones snagged four bars in side-by-side comparisons. The myTouch lets you know when no 3G is available via the icons at the top of the display. What's important is that I didn't miss any calls with the myTouch. It rang no matter where I took it. Data, on the other hand, was hit-or-miss. Sometimes it connected instantly, other times it timed out a bit before finding a connection.
Sound
The myTouch 3G can be made plenty loud. Set to full volume, ringers were easily heard in a loud coffee shop, even from the other side of the room. In louder places, such as bars, you might want to use vibrate as a back-up. The vibrate alert was strong enough that I never missed a call. As for the earpiece, ditto. Set up high enough (as in all the way), I easily heard callers even in loud rooms. Set to 60%, it was still easy to hear callers. Most calls were nice and clear. I noticed few quality issues.
Battery
Compared to the G1, HTC has made some serious improvements in the power management department. The G1 barely eked out a single day of heavy use. The myTouch fares better. With concentrated, heavy use in 3G areas, I was able to get at least a day and a half of battery life from the myTouch. That was with constant email, browsing, Twittering and messaging. Adding in usage such as video capture/playback and audio playback, and subtract half a day. In the end, you're probably going to have to charge it every day, but at least you can leave the charger home when you leave in the morning and expect to make it through an entire day without the danger of killing the battery before you get home.
