Apple iPhone 6s vs Samsung Galaxy S6 vs Sony Xperia Z5: specs comparison

Apple iPhone 6s vs Samsung Galaxy S6 vs Sony Xperia Z5: specs comparison
It's that time of the year when the major players on the market have already unveiled their flagships and major top-end devices for the year. Apple just unveiled its 2015 rendition of its iPhone, the iPhone 6s, whereas Samsung has been selling its flagship smartphone for half an year now.Additionally, just a couple of days ago at IFA 2015, Sony showed us its Xperia Z5 forerunner. A rather well-rounded trio indeed.

Unlike the Galaxy S6, which comes with brand new design, the iPhone 6s and the Xperia Z5 come with mostly under-the-hood and feature improvements, while they are still styled after their direct predecessors. Actually, the iPhone 6s brings about one of the more major mid-cycle specs upgrades Apple has ever committed to. The majority of new specs that are on board have been on fans' wishlists for a long time now, and finally Apple succumbed.

Meanwhile, we have two pretty potent offerings in the face of the Galaxy S6 and the Xperia Z5. The first one is certainly a step in the right direction for Samsung, while the Xperia Z5 seems like an able-bodied trooper that might have hindered the Snapdragon 810's overheating issues.

In case you've been wondering, here's how the top-end trio fares specs-wise.

Yes, it comes with the SD810. And it does a great job judging from the hands-on video's how blazingly fast the Z5 is.

I need a ram confirmation please PhoneArena. I also need a confirmation on split view slide over, and picture-in-picture please.

I think if there was an additional GB of RAM apple would have included it in the "show"!
