Think thin - here are the five thinnest large-screen smartphones
Sony Xperia Z Ultra - 0.26in / 6.5mm
At launch (July 2013), the Xperia Z Ultra was the thinnest 6.5mm watertight phone with the largest 6.44" screen. In 2015, Huawei went on to dwarf Its elephant display size, but the Z Ultra is still the thinnest large-screen smartphone. Back in the day, it used to offer flagship performance too - it runs on a 2.2 GHz Snapdragon 800 chipset, which is still a potent piece of silicon. Moreover, the Xperia Z Ultra allows you to write on its screen with any regular pen or pencil whose tip is more than 1mm in diameter, in addition to stylus input functionality.
Huawei P8max - 0.27in / 6.8mm
Huawei miscalculated when it announced the P8 Max as the world's thinnest large-screen phone, because the Z Ultra is still 0.3mm thinner. But this doesn't change the fact that the P8 Max has a very large screen, and is also very thin. It wields a giant 6.8-inch screen, but it has a slim 0.27in / 6.8mm frame. It also boasts a formidable specsheet that sings to the tune of 8-core Kirin 930 CPU, Mali-T628 GPU, 3GB of RAM, and a humongous 4360mAh battery that will keep the lights up for quite some time!
Xiaomi Mi Note Pro - 0.27in / 6.95mm
The Xiaomi Mi Note Pro is the Chinese upstart's answer to the Apple iPhone 6 Plus - it looks about as good, and its spec sheet sound much buzzier on paper. The 5.7-inch phablet features a 1440x2560 resolution screen from JDI, which makes for a peppy 515ppi pixel density. It's also outfitted with as much as 4 GB of RAM that handles computing together with a Snapdragon 810 CPU. It's a genuine superphone, but that's not all. It also rocks a 13 MP rear Sony camera with optical image stabilization, and a 4 MP UltraPixel front-facing unit. The little that isn't filled out by flagship internals is taken by a 3090 mAh battery.
iPhone 6 Plus - 0.28in / 7.1mm
The iPhone 6 Plus needs no introduction at this point. It is Apple's largest smartphone ever and offers a 5.5-inch display with a resolution of 1080 x 1920 pixels, good for a pixel density of 401 ppi. It is powered by Apple's 64-bit dual-core A8 processor along with an 8-megapixel iSight camera with optical image stabilization and a two-tone LED flash.
Huawei Honor 6 Plus - 0.28in / 7.5mm
In addition to a dual camera setup, the phattest phablet in our line up flaunts a 5.5" 1080p display, 1.8 GHz octa-core Kirin 925 chipset, 3 GB of RAM, and 32 GB of storage, plus a microSD slot for expansion. In that ample bodied smartphone, Huawei fit a generous 3600 mAh battery unit - as you can, the Chinese mogul has a steady track record of making huge batteries happen in portable handsets. Since you'll probably ask, that rear camera takes 13 MP shots, but actually consists of two 8 MP sensors with 1.85 micron-sized pixels and a dedicated image signal processor. One of the cameras dons f/2.0 aperture and autofocus, while the sidekick sports f/2.4 and a fixed focus setup.
