HTC is reportedly developing the successor to the One Max, a large-screen smartphone introduced last year.

Sources claim the new HTC One M8 Max follows the footprint of the original One M8 in terms of design, with a similar metallic construction but larger display, according to TKTechNews.

But the device, earlier rumoured as the HTC One M8 Prime, will receive an upgrade in terms of processing power. The latest disclosure suggests that the One M8 Max will be powered by a quad-core Snapdragon 805 processor. This is a notable feature when compared to the current HTC One M8 and One Max, which use Snapdragon 801 and Snapdragon 600 respectively.

The Snapdragon 805 is the same chip that has been rumoured to be used in a few upcoming high-end devices including the Samsung Galaxy Note 4, Galaxy S5 LTE-A and Sony Xperia Z3.

HTC's latest large-screen smartphone will retain the Max name. Apart from that, details are scarce at this stage about the handset and other features.

Rumours from ealier this year suggest the HTC One M8 Prime will be unveiled in September, and feature a 5.5 quad HD display, 18-megapixel sensor for depth perception and a five-megapixel UltraPixel camera sensor as a main unit. It is said to have 3GB RAM and 16GB internal storage.
