Xiaomi Mi Max Review: Hulked Up: Display, Connectivity, Battery

Display

The display is the very reason why the Xiaomi Mi Max form factor exists. The most popular size at the moment is 5.5" with a few 5.7-inchers and even some sixers out there. But the Mi Max is a rare breed that pushes the envelope well above the 6" mark.

The 6.44" diagonal is the defining feature of the phone and despite its mid-range status, Xiaomi didn't skimp on the quality.


The 1080p resolution is enough to secure a pixel density of 342ppi, which is high enough to qualify as Retina-grade and above. QHD would have been nice, but still, the image is sharp enough even for small, thin type.

We were worried about the brightness, but as it turns out, it's pretty much par for the course. Compared to some other 6" devices, the only one that stands out is the Galaxy A9 on Auto brightness, where it enjoys a brightness overdrive in extra colorful conditions. The AMOLED-packing Oppo R7 Plus, on the other hand, was darker.

The screen's contrast ratio, however, is nothing to write home about, the issue is mostly with the relatively high black levels (even compared to last year's Xperia C5 Ultra). It's by no means bad, though.

Oppo R7 Plus - 351 ∞

From the settings you have the option to boost the contrast of the image if you prefer the punchier look. One mode just boosts the contrast, the other adapts it to the ambient light.

From here you can also tune the white balance - from Warm through Neutral to Cool. The colors are fairly accurate for this class, an average deltaE of 6.6. That's almost as fine as the Huawei Mate 8 and slightly better than the Galaxy A9.

We found the Neutral setting to not quite live up to its name, the white and gray colors have a blue tint. Yet, we found that the color accuracy improves if you push the white balance slider towards Warm. The white balance improves quickly (but magenta goes off).

The Mi Max has an IPS display and the viewing angles are very good. The sunlight legibility, however, does leave something to be desired. It's better than some popular phones like the Redmi 2 or the OnePlus One, but there are strong performers like the Oppo R7 Plus and its AMOrganic Light-Emitting Diode (OLED) screen.

Connectivity

The Xiaomi Mi Max is a dual-SIM phone with LTE connectivity. One card is nanoSIM the other micro and the slot is a hybrid solution, which allows you to replace one of the SIM cards with a microSD card.

Since we're reviewing the Chinese model, we also have to mention that there is support for China Unicom LTE and CDMA.

There's also Wireless Fidelity (Wi-Fi) ac with MIMO support, so the phone will benefit from a quick router if you've got one. Bluetooth 4.2 is also available. For positioning, you acquire GPS, GLONASS and, quite naturally, Beidou.

The IR blaster is located at the top of the phone and, coupled with the correct software, you can utilize it to remotely control pretty much any IR controlled home appliance. Xiaomi provides its own MiRemote app, which supports a long list of devices correct out of the box.

The microUniversal Serial Bus (USB) 2.0 port on the bottom is a bit of a surprise, considering Xiaomi has been moving up to Type-C for a while now. Still, the port supports Universal Serial Bus (USB) On-The-Go if you need to access some external storage or utilize a Universal Serial Bus (USB) accessory.

Battery

The massive 4,850mAh battery of the Xiaomi Mi Max matches its larger-than-life demeanor. With a reasonable classy screen and chipset, it's set to be a champ.

The Endurance rating works out to 108 hours, you'd be hard pressed to find a device that lasts longer. Even adding a second SIM doesn't have a huge impact, dropping to 102h Endurance.

The individual tests are remarkable too. Talk time is a day, that's 24 hours! The web browsing is particularly impressive at 19 and a half hours, only two phones lasts longer (and they are battery-focused, have 720p screens and lower-discontinue chipset). The video playback is remarkable too, just not quite as amazing.


Note that while the Xiaomi Mi Max does not come bundled with a Quick Charger, it can definitely benefit from a Quick Charge 2.0 or 3.0 power brick. The charger we got in the box was 5V * 2A = 10W, but we got readings as high as 15W with several Quick Chargers we tried (the exact voltage and amps differed, but total power was always 14W-15W). So you can expect a 40%-50% bump in charging speed if you have a more powerful charger at home.

The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
