Introduction

This is the LeEco Le 2 X527 (Russia/International).

Hardware

This device is powered by a powerful Qualcomm Snapdragon 652 MSM8976 (Quad 1.8GHz Cortex A72 +

Quad 1.4GHz Cortex A53 CPU and Adreno 510 GPU), together with 3GB of RAM and 32GB of ROM. Unlike previous LeEco devices, this is the Russian/International variant ready-to-use in Russia and all European Countries thanks to the preinstalled Google Services and the support to many LTE Bands (1/2/3/4/5/7/8/20/38/40/41). Everything else is exactly the same as the X520 (Chinese) and X526 (Indian) variants.

Unboxing

Packaging comes with some accessories: 1x Type-C Full Reversible USB Cable, 1x Quick Charge 3.0 (5V up to 12V) USB Charger, 1x Quick Start Guide, 1x Warranty Certificate, 1x Type-C to 3.5mm Headphone Jack (yeah, no built-in jack is here), 1x SIM Card Tray Tool, 1x TPU Cover and the Smartphone (of course).

The package itself feels, and looks, premium. Considering the price target of this device, it is pretty interesting to find such a good amount of accessories included, especially the QC 3.0 charger.

Just like all LeTV/LeEco devices, also this one features a Metal Chassis with Plastic Antenna Bands on the upper/lower sides of the rear. The device itself feels solid, pretty compact and well-made.

It is 15.12x7.43x0.79cm, probably one of the most compact 5.5" devices you can find, with huge bezels though. As regards its weight, it is super lightweight, only 156g.

On the front side there is the Standard (no 2.5D Curved) Display and the upper front side of the device features a Front-Facing Camera (with an interesting sensor size), an Earpiece, and the Sensors hole that includes Light and Proximity Sensors.

An RGB Notification LED is here, on the left.

On the lower front side there is the Touch Keys area, with Multitasking, Home and Back touch buttons. All buttons are backlit. (pretty bright too)

On the back side there is the unibody metal chassis, as mentioned before.

The upper rear side of the device features the Camera Sensor (OmniVision OV16880) supported by a single rounded Flashlight (Dual-Tone), and the huge Fingerprint Scanner with a mirror-like surface.

On the lower rear side there is just the LeEco logo with other minor things because the Speaker is placed near the USB port.

Device

Screen

LeEco choose to use a BOE screen (with NT35596s display controller) and the quality seems to be pretty good. I have not noticed any kind of issue, it is bright, with customizable color presets and excellent viewing angles.

Light Sensor supports ultra-smooth light changes, this is its maximum brightness.

Viewing Angles are as good as you would expect from an high-quality IPS panel.

Also the Touchscreen Panel is excellent, 10 points supported.

Camera

Something interesting about this device is the Rear Camera Sensor, an OmniVision OV16880 (16MP) with Optical Image Stabilization (OIS), PDAF and F2.0. Personally i found it to be great for photos in high and medium light conditions, but pretty average in low light conditions.

Photos taken using the default Photo mode are just fine, with an high amount of details and almost no image noise. Thanks to the image stabilization it is rare to not get a decent shot.

"HDR off" on the left and "HDR on" on the right.

Here you can see some photos taken without HDR and in different light conditions.

The Flashlight is super powerful, but it isn't real Dual-Tone. It is just a standard LED covered with a Dual-Color Plastic. Basically it looks pretty warm everytime, in any condition. A real Dual-Tone Flashlight has an indipendent LED for each color, with the software that chooses which one to use.

Macro Photos look decent, a bit out of focus if you don't play a lot with the tap-to-focus feature.

As regards Video Recording, the camera is able to record 4K and Full-HD videos at maximum 30FPS (no 1080p60 is here), and the quality is good even though the Optical Image Stabilization doesn't seem to be super-efficient compared to other devices. I might post a Camcorder Sample soon.

The Front Camera is probably not as good as you would expect from an high-quality 8MP camera sensor, seems to have some focus issues. Just like the Rear Camera, also this one suffers a bit in low-light conditions.

Audio

This is where LeEco shows its capabilities. Everything, starting from the Speaker ending with the Microphone, is perfect here. At least on my device, the speaker sounds great, with and without Dolby Atmos.

As you might have already noticed, this is a device that doesn't feature a 3.5mm Headphone Jack. It uses CDLA (Continual Digital Lossless Audio) instead, that provides the best audio quality using the USB Type-C port.

Even using the 3.5mm adapter you will get higher audio quality compared to standard 3.5mm devices. Ok, this is not a feature that everyone would appreciate, because you can't charge the device in the same time while using your Headphones, but for audiophiles this is definitely an appreciated feature.

The Microphone works perfect, the same applies for the Earpiece. I have tested it with Normal 3G Calls (no VoLTE is available here) and VOIP, everyone was able to hear my voice perfectly and i had no issues in hearing the third-party too.

GPS

When it comes to GPS Quality all Qualcomm Devices work great, Mediatek and others still have to learn a lot in this area, and as you might notice here the GPS is working perfect. More than 24 satellites in view outdoors, and indoors it is able to get some signal enough to get a more or less precise location.

Telephony, Mobile Network & WiFi

Thanks to the 4G Band 20 support (some other Chinese Smartphones don’t have it, including some other LeEco devices), i was able to get some 4G signal almost everywhere.

4G Network Speed is higher than average, other devices tested in the same room, same position, were not able to get such high speed (photo on the left). I have also tested other bands speed (well, others supported by my Mobile Operator), result on the right.

WiFi 5GHz is supported here, and its speed is great. It supports only 1x1 Stream (Snap 652 WiFi Hardware limit), enough to get almost full-speed from my Broadband Internet Connection. (VDSL 100/20)

Battery Life

I have measured the real battery capacity using my USB Tester, and it seems that the real battery capacity matches the declared one. (declared 3000mAh, real ~3010mAh).

I lost my PCMark Battery Test (software bug), but i managed to find its duration in the Battery Stats. Not a great battery life unfortunately, lower than average, barely reaching 4 hours of screen-on time.

As regards battery charging times, thanks to the Quick Charge 3.0 support, together with the already included QC 3.0 charger, i managed to full-charge the device in almost no time. I will not say how many minutes because it highly depends on the device's temperature and other factors.​
