LG Nexus 5X review: Settling down

Settling down

GSMArena team, 16 November, 2015.

Screen

Back in 2013 when the Nexus 5 came out, LG had the G2 - a phone with a 5.2" 1080p screen. Not that we'd push for QHD resolution at this diagonal, especially at this price and with this GPU. Still, a comparison is inevitable.

LG Nexus 5x review

So we're pleased to report that two years of progress in display tech has brought better contrast and colors than the previous model. There are no controls for adjusting the screen colors though.

The LG Nexus 5X is impressive even at a quick glance, and our test more than proved what our eyes saw. The maximum brightness level (455nits) may not be class leading, but the achieved contrast ratio of 1542:1 is excellent due to the nicely deep blacks.

Another nice finding is the fact that the screen is calibrated for almost perfect color rendering right out of the box. Its a rare sight to see a phone with an Avg. DeltaE of only 2.3 (based on the primary colors plus black&white) as anything below a deviation of 4 is considered calibration-grade color output.

Additionally, the minimum brightness level is only 1.8nits for white content, which means that you should probably be quite comfortable using the Nexus 5X display in dark environment without any eye strain.

Xiaomi Mi 4c 0.08 121 1613 0.28 452 1609


The low reflectivity of Gorilla Glass 3 and high contrast of the screen allow it to remain legible even in bright sunlight. The 5.2" screen of Nexus 5X is well above average in this respect.

Connectivity

The LG Nexus 5X comes equipped with an LTE Cat. 6 modem for speeds up to 300Mbps down and 50Mbps up. Aside from GSM, the US version of the phone will also have CDMA for compatibility with Verizon, Sprint and Google Fi.

Besides that you have the usual Wi-Fi a/b/g/n/ac at 2.4GHz and 5GHz and Bluetooth 4.2 with A2DP. NFC is on board, naturally, to be used with the new Android Pay.

The USB Type-C cable will transfer data at USB 2.0 speeds despite the fact that the provided cable is Type-C on both ends and we expected it to deliver the benefits of the Type-C tech. To make matters worse, you'll either need an adapter or a whole new cable to plug this guy into your computer unless you own one of those recent Chromebooks.

Also, by default the phone connects in charge-only state to the computer, so you have to manually enable data transfer every time. Google really does not want you using wired transfer.

The USB port can be used to hook up storage and USB periphery (but again, stuff with the C plug is quite rare). As mentioned earlier, there's no TV-out - no SlimPort, MHL or anything. You're stuck with the wireless Cast method.

Battery life

The LG Nexus 5X comes with a 2,700mAh battery, not big for its size, but a definite improvement over the 2,300mAh battery that the 2013 model got. And it has a new OS feature to make sure the battery is used efficiently.

Doze detects when you are not using the phone and the longer that goes on, the less and less it allows apps to do work in the background - it's wasted effort that the user won't notice (other than the used up battery charge).

The standby power draw of the Nexus 5X is pretty good, especially for this capacity. Even so the total standby rating isn't that high, the poor video playback in particular drags down the result.

Talk time is okay at 17 hours, but the aging LG G2 did 25 hours (it also had a bigger battery though). It's a massive improvement for owners of the 2013 Nexus 5 though. Things get better - the 5 was one of the worst performers in web browsing, the 5X now lasts nearly twice as long in the same test. Still, we've seen better performing mid-rangers.

Finally, the poor video support (more on that in the video player section) left the Nexus 5X with an unimpressive score of 6 and a half hours. Better than before, but not good for 2015.
