The Lifestyle model is a 5.5-inch device with a 720p Gorilla Glass display, quad-core Qualcomm Snapdragon 400 processor, 2GB or 3GB RAM, 16GB or 32GB expandable storage, a 13-megapixel f/2.2 rear camera, 5-megapixel f.2.8 front-facing camera, and 24-bit Hi-Res sound certified by Dolby Audio.
The Pro handset is the same size and has the same storage capacity options and audio features, but comes with a 1080p display, 64-bit Octa-core MediaTek Helio P10 processor, 3GB or 4GB RAM, a 20-megapixel f/2.2 camera with laser autofocus, a 13-megapixel f.2.2 front-facing camera with selfie panorama, and a fingerprint reader.
The two "Art Deco" inspired phones – which include a headphone jack – are matte plastic with a metal trim, and take design cues from the HTC 10, the company's flagship smartphone for 2016, coming on the heels of last year's HTC One M9 device. Both phones will be available in black, white, light blue, and dark blue.
HTC's new Desire 10 range represents the company's attempt to compete below Samsung's and Apple's flagship high-end smartphones, in a cheaper market segment populated by devices like the Moto G4 and Moto G4 Plus.
HTC says the handsets will be released exclusively in Europe to begin with, with the Lifestyle available from today and the Pro model coming in November. Prices are as yet unconfirmed for the latter model, but the Lifestyle costs £249, which converts to around $325.
Some MacRumors readers may remember HTC was forced to deny claims last year that the company's flagship One A9 copied the iPhone. Apple declined to comment on the claims, but has taken legal action against Samsung for perceived copying in the past.
