Review: HTC Titan II for AT&T
The T2's display measures 4.7-inches and includes the standard 800 x 480 pixel resolution that all Windows Phones share. It looks good, but it isn't as impressive as the HD panel HTC put on the One X, for example. The resolution limitation is one that Microsoft, not HTC, needs to surmount, and I find that it puts Windows Phones at a bit of a disadvantage now. All that said, the T2's display is still very good. It's sharp, clear, colors look great, and it can still be used out in bright sunlight.
On AT&T's HSPA+ network, the T2 performed on par with other AT&T phones. That means it showed the same number of bars in a given area. I found the T2 often got "stuck" a few times. It would flat out refuse to pull down data even though it reported 4 or 5 bars of coverage. When it was in this state, it couldn't use the data network at all, even though other AT&T phones could. Only a reboot would fix it. The T2 was able to make phone calls, though. In fact, I had no trouble making calls at all with the T2, nor did the phone drop any.
As for AT&T's LTE 4G network, the T2 found it, but waffled a lot between HSPA+ and LTE. It didn't stay firmly connected to LTE in New York City for long before it would drop to HSPA+. I can't say that data speeds over LTE were any better than they were over HSPA+. It all felt about the same to me. By way of comparison, the Nokia Lumia 900 was more consistent about connecting to AT&T's LTE network and remaining connected to it.
The T2 is a very good voice phone. I made a number of calls when walking about Manhattan and found the quality of calls was excellent. The earpiece was plenty loud enough and could be heard above the herds of tourists cavorting about Times Square. The speakerphone sounded just as good, and was also loud enough for most places you might need to hear it. Ditto for ringers and alerts. I had no trouble hearing the T2 no matter how much background noise there was. The vibrate alert isn't totally awesome, but it's not terrible.
Battery life with the T2 depends highly on where the device is used. When used in 3G-only areas, the battery is fine. It easily lasts an entire waking day. When used in areas with LTE 4G, however, it drains much faster. How fast? Try from a full charge to less than 50% in about 5 hours. In this 5-hour period, I was using the device to check email and Twitter, to take pictures, and browse the web. I also used maps for a bit. I didn't listen to music, nor watch video, nor use Wi-Fi or Bluetooth. I'd call it average use. I suspect heavy use under LTE coverage could lead to a dead battery by dinner time. (There's no control for turning off the LTE 4G radio, it remains on constantly.) In other words, be careful when you're using the 4G network.
