The huge battery along with not too powerful MediaTek processor should easily allow for several days, if not a full week of operation.

"users who travel a lot" would really like to have a smartphone that can fit into small pockets and single-hand-friendly, which means smaller screen (and/or bezel sizes), which will also attract less attention from your surroundings whenever texting, gaming and reading ("hey everyone look at me I got the biggest flint(stone)-phone in this room"), especially for PC gamers, road warriors and even writers who don't need their phones and their computers to be the same unit. Thanks Oukitel, but no. I'm still happy with my 4-incher in my pocket, and a power bank in my bag.
