Review: HTC One VX for AT&T
The VX has a 4.5-inch LCD panel that offers qHD resolution (960 x 540 pixels.) The resolution and size together mean the screen looks very good, though it falls just short of great. I was easily able to make out individual pixels when I held the device about 9 inches from my eyes. I wish it rendered sharper edges on text, pictures, and icons. It’s plenty bright, however, and I had no trouble using it under the bright desert sky in Las Vegas.
The VX does a fine job of attaching itself to AT&T's network. I was able to test it in NJ and in Las Vegas and had no trouble with it in any location. When LTE was available, the VX was quick to lock on. It transitioned seamlessly to HSPA+ when LTE was not available. The phone connected most calls right away, through it dropped a few in the (very busy) Las Vegas Convention Center. Data speeds were good all around, and LTE, in particular, worked very well in Las Vegas, despite the added presence of 150,000 conventioneers.
Phone calls sounded quite good. I was pleased with both the quality and volume coming from the VX's earpiece. Calls had a crisp and clean sound that was free of interference. The volume, when set all the way up, is good enough for all but the loudest environments. The speakerphone also had good quality and solid volume performance. I have no complaints whatsoever. Ringers and alert tones were all loud enough to alert me when I needed them to. The vibrate alert has plenty of buzz to it.

The VX's non-removable battery holds 1810 mAh. It’s enough to last an entire day most of the time. It routinely lasted from 7am to 10pm with heavy use under LTE coverage. (Battery life of LTE 4G phones has come a long way since 2011!) No single app or service appeared to have a negative effect on the battery. I wish it would have lasted until 11pm or Midnight, but 15 hours may be good enough most of the time. You'll need to charge it every night.
