HTC U Ultra counts with a little longer battery life than Samsung Galaxy S6, because it has a 3000mAh battery capacity against 2550mAh. Galaxy S6 shoots a bit better photographs and videos than HTC U Ultra, because although it has a tinier sensor which gives a worse image and video quality and a tinier aperture which is not recommended for shooting images or videos in poorly lited situations, and they both have the same video frame rate and the same (4K) video definition, the Galaxy S6 also counts with a way higher resolution camera.
In addition to being the best phone of the ones we are comparing here, the Galaxy S6 is also very cheap compared to the other ones, which makes this phone an obvious call.
