“With a brilliant design, big battery, and bargain price, the Redmi chú ý 4X is crying out for international support.”

Xiaomi may capture headlines for stunning, high-power smartphones lượt thích the mày Mix and the mi 6, which are great devices; but arguably the company does low-cost hardware with strong spec lists better. Its latest is the Redmi note 4X, an update lớn 2016’s Redmi note 4, which costs about $160 depending on the màu sắc you choose. That’s not very much money for a điện thoại thông minh today, especially one with features lượt thích the lưu ý 4X.

Like all xiaomi mi phones, if you want to own one outside China, you have to use an import service lớn get it. It’s not difficult, but it can be a challenge down the line if the phone breaks, và making sure it connects to your chosen network. It’s extremely tempting khổng lồ pick up a $160 phone that looks like it should cost twice that, so should you?

We’ve been using the Redmi lưu ý 4X for the last two weeks to find out, và the answer is no. It’s a fantastic phone for the price, but the dealbreaker is its lack of 4G LTE connectivity.

Stylish design

If you’re familiar with the Redmi chú ý 4, little has changed with the Redmi chú ý 4X. Two small screws on both sides of the Micro
USB charging port have been removed for a cleaner look, and the antenna bands have been minimized và replaced by shiny strips, rather than cheap-looking white plastic. Nothing major, but enough to make the chú ý 4X a modern, sleek looking phone you’ll be proud to lớn hold.

It’s quite thick at 8.5mm, but it’s comfortable khổng lồ hold due khổng lồ a 2.5 chiều piece of curved glass over the screen, & a perfectly curved aluminum rear panel. Cradling the Redmi lưu ý 4X, you’ll find it ergonomical. The power nguồn button falls easily to thumb or finger (depending if you’re left or right handed), and the rear-mounted fingerprint sensor is ideally placed, so your finger avoids the camera lens above it. It’s a grippable phone, và one that doesn’t feel too slippery.

If you lượt thích phones without much branding, the Redmi cảnh báo 4X will please you. Only a Mi logo sản phẩm is etched into the back, & the usual three app android capacitive keys sit below the screen, glowing when the phone is awake. The note 4X is available in several different colors, including silver, gold, black, & pink, plus the light green version seen here. The light green has a slight matte effect, but retains a decent light-catching glow, as well as a subtle, tactile texture. Phones in multiple colors are becoming more popular, & to find such chất lượng hues on a phone so competitively priced is very welcome.

Minimalist, stylish, and pleasant lớn hold, it’s surprising the Redmi note 4X costs so little.

Bright screen, long-lasting battery

The Redmi lưu ý 4X has a pixel XL-size screen, and it’s big, bright, & beautiful. It’s not an AMOLED panel though, but an IPS LCD screen that measures 5.5-inches và has a 1920 x 1080 px resolution. It can’t compete with the pixel XL, the Galaxy S8, or the LG G6; but holds its own against the One
Plus 3T, various Honor phones, và even some more expensive Huawei devices like the P10 Plus.

There are plenty of customization options. A Reading Mode reduces glare và cuts down on sleep-disturbing blue light, plus adjustments can be made lớn the color and contrast, helping tailor the screen’s look to lớn your personal preference. It’s also very bright with a maximum output of 450 nits, and it’s easily viewable in bright sunlight with the brightness slider cranked right up. The ambient light sensor is quite aggressive though, & it doesn’t recognize when you’re looking at the screen, resulting in the brightness dimming at inopportune moments.

A massive 4,100m
Ah battery keeps the screen on — that’s enormous compared khổng lồ most flagship smartphones. The result? At least two days use. Yep, we said, “at least.” Leave the phone on standby, và use it normally through the day, và you’ll be charging on the third day. The Redmi cảnh báo 4X sips from a vast well of battery power. Unfortunately, that well isn’t quickly replenished, due to no fast-charging system, so plan for a two hour recharge when it’s close to lớn empty.

Android Marshmallow, & solid performance

Here’s the big difference between the older Chinese Redmi chú ý 4 và the new globally compatible lưu ý 4X: It has a Qualcomm Snapdragon 625 processor inside, rather than a Media
Tek chip. The Redmi cảnh báo 4X is almost identical lớn the international version of the note 4 released after the Chinese version though. Confused? Don’t be, just remember the Redmi note 4X is the mã sản phẩm to buy, & you’ll be fine. There’s a version with 3GB of RAM & 32GB of storage, and another with 4GB of RAM & 64GB storage space. Our đánh giá model is the former.

Judging whether a điện thoại cảm ứng thông minh has enough performance isn’t that complicated. We use the phone daily, for a similar range of tasks, and if it’s slow, buggy, or annoying, it gets a big strikethrough next lớn its name. We’d never expect lớn see this with a device that costs $500 or more, but one that costs less than $200? That seems more likely. The fantastic news here is the Redmi note 4X is strikethrough free.

After a solid hour playing games, reading email, checking social networks, và generally zipping between the home screens & different apps, the Redmi note 4X hadn’t stuttered. Its very hard lớn argue against a phone that costs so little, yet performs so well. Running An
Tu
Tu 3 chiều benchmarking chạy thử returned a 62,771 score, while 3DMark’s Slingshot Extreme returned a score of 461, neither of which mix the record charts alight, but are consistent with the Snapdragon 625-powered Huawei Nova.

The phone runs android 6.0.1, with Xiaomi’s MIUI 8.2 user interface over the top. It’s one of the best third-party user interfaces out there, with the biggest change over stock android being the lack of an phầm mềm drawer. All your apps are spread over multiple trang chủ pages, just lượt thích Apple’s i
OS. Game android purists will be annoyed by other small changes, such as the altered notification shade, custom icon designs, và other visual tweaks throughout the operating system. Google Play came pre-installed on our phone, but be aware that due to the custom nature of MIUI, some apps — such as the updated Netflix app — may not work. It’s a rarity this happens though, và every other phầm mềm we used operated without a problem.

Is it all good news? No. The Redmi lưu ý 4X is still a mid-range phone, with a mid-range processor, and a custom UI. This means scrolling isn’t always buttery smooth, some of the transitions are a beat too slow, và in some games when the going gets really tough — driving the fastest cars in Reckless Racing 3, for example — there’s evidence of frame rate drops. Android Pay also won’t work, as there’s no NFC onboard.

Still, for the price, the Redmi cảnh báo 4X is a solid performer. It’s a shame it does not come with the latest version of Android.

Good camera

A 13-megapixel rear camera sits at the top-center, và it’s good. That’s right. Good. It’s not often we get to praise what has become a very typical camera setup, but the pictures we took with the Redmi chú ý 4X were pleasing, offering detail, và handling challenging light in a satisfactory way.

It’s still far from perfect, and the f/2.0 aperture does limit its capabilities in low light, but show it some sunny skies or an expansive landscape, & the results are eyebrow-raisingly good. Yes, it washes out the sky on overcast days, & no, it doesn’t have two lenses or a wealth of different modes. However, take regular photos in everyday situations and you’ll likely be happy with the results.
