Specs leak: HTC One M8i variant with octa-core processor and 13MP/2MP DuoCamera suggested
From what we're told, the M8i will be quite similar to the original M8, while simultaneously differing significantly. What do we mean? Well, to start off, the M8i will supposedly come in at essentially the same dimensions as the M8 and also even weigh as much (which would suggest a metal body, even though that's not been specified). Like the current HTC flagship, the M8i will also have a 5-inch screen with 1080 x 1920 resolution, 2GB of DDR3 RAM, BoomSound front-facing stereo speakers, microSD slot, NFC, Bluetooth 4.1, and a battery with a capacity smaller "than 3000 mAh".
Where the M8i differs is the processor – it will utilize a mid-range octa-core Snapdragon 615 with four 1.7GHz cores and four 1.0GHz ones. Also different is the rear shooter – we again have a DuoCamera solution (so bokeh effects), but this time around it'll be a 13-megapixel main sensor with a 2-megapixel auxiliary one. The front-facing snapper is listed as a 5-megapixel unit, but "optimized to Selfie", so we can speculate that some of the software features available to the Desire EYE will make it to the M8i as well.
According to @upleaks, the M8i will be available with the same paint as the M8 – grey, gold, and silver. For the time being, we're told to expect this new variant of the M8 in Asia (M8_QL#TUHL) and Europe (M8_QL#UL).
