The key to HTC’s speed claim is three-channel carrier aggregation, an E protocol that combines three bs of the wireless spectrum to widen the pipe, as it were, deliver faster data for supported devices. HTC says it tuned the software that manages the Bolt’s E modem to get the most from its aggregation protocols. That may be especially helpful because the phone runs the Qualcomm Snapdragon 810 processor, which is no longer state-of-the-art. Three-channel aggregation is carrier dependent, Sprint has only deployed the technology in Chicago, San Francisco, Minneapolis, Dallas, Denver, sas City, Clevel Columbus. So buyer beware if you don’t live in one of those cities. The Bolt has a very premium-looking, aggressively chamfered body that recalls the design of the HTC 10. It looks unique in a sea of homogeneous phone designs, I love the rugged teeth on the power button. The Bolt is water-resistant to I7 (meaning in can survive 30 minutes in a bath tub), comes with a front-mounted fingerprint sensor, a 16-megapixel rear camera, 3GB of RAM, a 3200 mAh battery, an SD card slot for extra storage. For what it’s worth, the ione 7 is rated I7 Galaxy S7 is I8, so each a little better about dust ingress, but roughly equal waterproofing. The D display looks great with a 2560×1440 resolution, but it doesn’t appear particularly bright compared to all the phones I’ve recently tested. HTC has always delivered attractive phones with great audio, in the Bolt that audio comes via bundled BoomSound Adaptive Audio earphones. HTC says the earphones build a “personal audio profile” based on the shape of your ears, then use that profile to balance ambient noise. The earphones sound good even with Adaptive Audio toggled off, but when the feature is on, everything sounds louder just, well, better. Bass is super strong without being overwhelming, the overall sound profile is best described as “thick.” I preferred the days when HTC put both its stereo speakers on front of its phones. The Bolt, like the HTC 10, positions one of the speakers on the bottom edge next to the B-C port. These external speakers don’t sound as good as the BoomSounds of old, so it’s reassuring that the Bolt comes with solid earphones— they’re wired! Interested? Remember, this is a Sprint exclusive. But if that’s your carrier, you’re a total HTC fan, you want a bigger phone that the HTC 10, you live in one of the markets that supports three-channel aggregation, this could be the phone you’ve been waiting for. It’s available now for $25 a month over 24 months.
