HTC and Sprint today announced the Bolt, the first smartphone to ship with support for three-channel carrier aggregation (3xCA) for Sprint's LTE Plus network. The HTC Bolt can aggregate three 20MHz LTE channels to improve wireless performance. Sprint claims theoretical max downloads via 3xCA can reach 450Mbps, but expects real-world speeds to be under 300Mbps. While the Bolt will be the first handset to ship with 3xCA active out of the box, Sprint said earlier this year the HTC 10 and 9, LG G5, and Samsung Galaxy S7 and Galaxy S7 Edge are all 3xCA-capable — they need only a software update to turn the functionality on. The HTC Bolt is a unibody metal handset that boasts IP57 for protection against water and dust. It includes a 5.5-inch quad HD screen with curved glass, Snapdragon 810 processor with 3 GB of RAM, 32 GB of storage, and support for microSD cards up to 2 TB. The main camera has a 16-megapixel sensor with an aperture of f/2.0. It has phase-detection autofocus, optical image stabilization, dual-LED flash, and 4K video recording. The user-facing camera has an 8-megapixel sensor and a selfie light. HTC gave the phone a 3,200mAh battery and the USB-C port supports Quick Charge 2.0 for rapid power-ups. The phone does not include HTC's trademarked BoomSound stereo speakers, but it does ship with BoomSound Adaptive Audio headphones. The headphones include microphones and work together with on-board software to fine-tune the EQ based on the owner's ear and surrounding environment for the best-possible sound. The phone ships with Android 7 Nougat and the latest version of Sense UI from HTC. The HTC Bolt reaches Sprint stores today (Nov. 11) for $25 per month for 24 months with an installment plan.
