Review: HTC myTouch 4G Slide
Screen
The myTouch has a 3.7-inch Super LCD display with 800 x 480 pixels. It looks fantastic. It is bright, colorful, and text, and graphics are nearly 100% free of any sort of pixelization. You'd have to break out a magnifying glass to see individual pixels. Indoor viewability is no problem. Outdoors, it dims some, but it's still readable for essential actions such as answering calls.
Signal
The signal indicator on the 4G Slide displayed two or three bars of coverage pretty consistently. Only a couple of times did it swing up to a full five bars or down to just one. No matter what the signal indicator showed, the 4G Slide was still able to access and use T-Mobile's network. Only once did I miss a call because the network couldn't find the phone (or vice versa). The 4G Slide works with T-Mobile's HSPA+ network at 14.4Mbps. It isn't the fastest service available from T-Mobile, but it is certainly fast enough for most situations. Web pages loaded swiftly on a consistent basis.
Sound
The majority of phone calls I placed with the 4G Slide sounded very good. There was often a slight background hiss during calls, but that was the only interference or noise I encountered. The earpiece is quite loud, and will be easy to hear most places you take the 4G Slide. Don't expect to be able to hear your friends while you're at that rock concert this summer, but busy city streets won't be a problem. Call quality through the speakerphone was equally clear, but not nearly loud enough. I had trouble hearing speakerphone calls in my quiet office, let alone somewhere noisy like a loud car. The ringers and alert tones were a bit on the weak side; I would have preferred more volume and strength from both.
Battery
The 4G Slide doesn't offer any pleasant surprises when it comes to battery life. As is typical for a modern smartphone, it lasted just over 24 hours from a full charge to absolutely dead. You can save yourself some battery life if you keep the social networking to a minimum. If you use it more for browsing, messaging, and email, you can squeeze a few more hours of use out of the battery life. Most of the time, you'll still probably need to charge it each night.
