The HTC One+ codenamed HTC M8 may not have the capacitive buttons or the home and back buttons that were a feature of the HTC One, if a source proves to be correct.
Rumour has it that there will be a 6MP or possibly an 8MP camera which should have the Ultra Pixel tech or the HTC ImageChip 3. We have also heard rumours of a possible double lens, which would mean better photos in low and high lighting.
The HTC One+ could have a battery of 2900mAh, if so it will have been boosted from the 2300mAh found on the HTC One and would mean longer battery life. The display has been rumoured to be around 0.3 inches bigger than that of the HTC One at around 5 inches.
We may see the Qualcomm Snapdragon 805 processor running the handset, as opposed to the Snapdragon 800. The HTC One+ may have support for microSD card and should arrive with KitKat 4.4 and HTC Sense 6.
