As a phone, the HTC 8XT sounds okay, but not great. Some people I talked too said I sounded a little bit robotic and I had to repeat myself at times. However, I could always hear the person on the other end very well. Perhaps I was in a bad area when I tested the phone quality, but some other reviews seem to echo my problems.
The 1800mAH battery certainly gives the 8XT respectable battery life. We were able to juice 6 1/2 hours by browsing the Internet for two hours with LTE, using the GPS for 20 minutes, making four phone calls and watching two half-hour videos. Most users will easily be able to get a full day's worth of use without having to run to recharge the phone.
The HTC 8XT is definitely a smartphone to look at. It has a lot of nifty features that will help you throughout the day. However, power smartphone users who crave high definition screens and a lot of useful apps may want to look elsewhere.
