The Device has a Qualcomm Snaprdagon 808 processor with six cores running at 1.8GHz and integrated Adreno 418 graphics. Theres 2GB of RAM which might seem low these days, but thats because it has become a gimmick to stuff 3GB or 4GB into even low-cost phones. You can choose between 16GB and 32GB of storage at the time of purchase, but it isnt expandable. You plug in a USB-OTG device .
The screen measures 5.2 inches across - not comically oversized, but still big. The 1080x1920-pixel resolution gives us an effective density of 423ppi, and sure enough, everything looks crisp and clean. Theres a 2700mAh battery, Wi-Fi ac, Bluetooth 4.2, GPS with GLONASS, NFC.
12.3-megapixel rear camera with a twin-LED flash and laser-assisted autofocus. The camera is identical to the one in the Nexus 6P, but this phones processor will only allow 120fps slow-mo recording while the latter can do 240fps. The Nexus 5Xs primary camera also supports 4K video recording at 30fps.
The Nexus 5X does not support wireless charging which might be a bit disappointment .
Nexus 5X has what Google calls Ambient Display, which is a way to see notifications on screen without using much power. The phone is supposed to detect when you lift it and turn the screen on in a monochrome mode. In practice, this didnt work well. It took a sharp jerk for the Ambient Display to kick in, and we found it easier just to reach for the power button instead.
The Nexus 5X was consistently pleasant to use. With this kind of hardware, its impossible to feel any stutters or lag when moving around the operating system. Some might feel that 2GB of RAM is too little, now that 3GB is becoming more common even in the budget segment, but this really isnt going to affect real-world performance in any meaningful way
