The LeEco Le Max 2 comes with the flagship-worthy resolution of 1440 x 2560px on a 5.7" diagonal. It's an IPS LCD with a standard RGB matrix. There is no fancy curved glass on top of the Le Max 2, nor is there any mention of using any kind of chemically strengthened glass (Gorilla, Dinorex). Perhaps, a screen protector might be a good idea for anyone opting for the Le Max 2.
The viewing angles of the 5.7" display are excellent and colors don't shift. There is some contrast loss, naturally, but it doesn't hurt the overall great picture quality.
The screen offers a maximum brightness of 426 nits, which is about average - being an LCD unit, it could have been brighter. Thanks to the deep blacks, however, the Le Max 2 display outed an excellent contrast of 1444:1.
Finally, the color calibration isn't perfect as the whites and grays are off towards blue, but with an Avg. DeltaE of 6.0 it isn't bad at all. Setting the color mode to Soft fixed the whites, but hurt way too much the blue color (deviation of 19). The LeEco mode is very close to the Natural setting, making some colors slightly more saturated but without hurting the average DeltaE of 6. Overall, you should be fine with the screen's color calibration unless you have some color critical tasks to perform.

The Le Max 2's solid average performance in our display tests continues into sunlight legibility. A score of 2.57 is a good achievement for an LCD panel and means you'll see what happens on the screen in bright sunlight despite the inevitable loss of contrast and color.
The LeEco Le Max 2 is powered by a rather modest (for the phone's size and specs) battery of 3,100mAh. It's not user-accessible either. The battery supports QuickCharge 3.0 and in our 30-minute charging test the phone's battery charged from 0% to up to 58% using the supplied QC3.0 charger in the retail box.
The Le Max 2 scored 67h in our test, which means you can count on the battery to last a little short of 3 full days if you do an hour each of calls, browsing the web and video playback a day. This is a usage pattern we've come up with, so our battery results are comparable across devices.
Adding a second SIM card cuts only 3 hours from the total rating. The rating takes a very small hit from an extra SIM, which is great, but the already average standby, video, and browser scores contribute to a rather uninspiring overall endurance.
LeEco offers lots of options to extend the battery life such as Ultra-Long Standby during sleeps, Align Wakeups for wakeup optimizations, and scheduled power on and off. We used the Normal Align Wakeups, while all other battery optimizations were disabled.

The LeEco Le Max 2, being a Snapdragon 820 smartphone, comes with the latest generation modem with rich LTE band support and Cat.12 speeds. It supports dual nano-SIM cards and can tap to an LTE network on either SIM, but once you do, the second one will be limited to GSM connectivity only.
The rest of the connectivity features include dual-band Wi-Fi a/b/g/n/ac support and Wi-Fi Direct. Wireless screen mirroring is available via the Miracast protocol.
There is also support for Bluetooth 4.2, NFC, GPS, and GLONASS. There is no FM radio support.
The Le Max 2 supports USB Type-C - it's the new reversible connector for USB that builds on top of USB 3.1.
The IR blaster is located on the top and coupled with the right software, it can be used to operate any remotely controlled home appliance, turning the Le Max 2 into a universal remote. LeEco has its own Remote Control app.
