Xiaomi Redmi Note 5 Pro vs. Mi A1: MIUI takes on Android One

Xiaomi surged up the ranks in India last year on the back of a flurry of launches in the budget segment. The first in that wave of devices was the Mi A1, which is unlike any other Xiaomi device previously released. Instead of the standard MIUI, Xiaomi teamed up with Google to bring Android One to the device, resulting in a device with a gorgeous metallic design paired with pure Android.

The Chinese manufacturer hasn't divulged Mi A1 sales figures, so we don't really know how many units have made their way to end-users. But if one infamous poll is to be believed, there's considerable interest in Android One over MIUI, at least for a subset of Xiaomi customers.

For its part, the Mi A1 was one of the best — if not the best — budget phone of 2017, thanks to its design, software experience, and blazing-fast performance. With the Redmi Note 5 Pro looking like a strong contender for the best budget phone of 2018, it's time to see how the Mi A1 has fared over the last six months and if it's a worthy challenger to Xiaomi's latest budget phone.

Where both are evenly matched

Xiaomi Redmi Note 5 Pro vs. Mi A1

From the very beginning, Xiaomi's focus on build quality allowed it to stand out in the budget segment. At a time when the category was rife with plasticky phones with shoddy construction and materials that flexed under pressure, Xiaomi introduced all-metal designs with an alluring design and outstanding build quality.

That reliance on quality paid off handsomely for the brand, and with the Redmi Note 5 Pro, Xiaomi is introducing even more rigorous quality control to minimize hardware defects. Sure, the Redmi Note 5 Pro is essentially using the same design language as the two-year-old Redmi Note 3, and while the aesthetic is starting to look stale, it is one of the most well-built phones available in this segment.

Out of the two, the Mi A1 looks more premium, and that's down to the design at the back. Both phones have been inspired by iPhone designs — the Mi A1 has the antenna lines from the iPhone 7, and the Redmi Note 5 Pro has the same camera arrangement as the iPhone X. But as we're seeing more and more often, if it's a popular design, phone manufacturers are going to steal the idea.

Both the Redmi Note 5 Pro and the Mi A1 have dual cameras at the back, but the former has the sensors arranged vertically whereas the latter features a horizontal configuration. Although both devices have dual cameras, the secondary sensor plays different roles in each — the Mi A1 has a telephoto lens and the Redmi Note 5 Pro features a depth-sensing module.

Xiaomi is one of the few manufacturers to offer IR blasters across its range of devices, and both the Redmi Note 5 Pro and the Mi A1 feature the module at the top of the phone.

What the Redmi Note 5 Pro does better

Xiaomi Redmi Note 5 Pro vs. Mi A1

The major design change with the Redmi Note 5 Pro is the switch to an 18:9 5.99-inch panel. Xiaomi is starting to offer taller displays in the budget segment with the Redmi Note 5 series, and the design itself isn't quite as bezel-less as the Mi Mix 2, and more in line with what we've seen on the Pixel 2 XL instead.

The taller size and reduced bezels means you get more screen real estate in roughly the same size as the 5.5-inch Mi A1. And although the Redmi Note 5 Pro has an 18:9 panel, the quality of the display itself is the same on both devices. Viewing angles are great, as are contrast levels and sunlight legibility.

An added bonus with the switch to the 18:9 form factor is the removal of the hardware navigation buttons, with Xiaomi now offering on-screen keys instead. The move makes it possible to switch the configuration of the back and overview buttons on the Redmi Note 5 Pro. The Mi A1, on the other hand, relies on hardware nav keys, with the back button located to the left of the home button and the recents key on the right.

The Redmi Note 5 Pro also wins out on the hardware front. Xiaomi switched to the 14nm Snapdragon 625 last year, choosing energy efficiency over sheer performance, and as a result there was a decline in power from the 28nm Snapdragon 650. The downturn was noticed mostly when playing visually-intensive games, with the Snapdragon 625 more than able to meet everyday usage tasks.

The Redmi Note 5 Pro sets a new benchmark for the budget segment.

With the Redmi Note 5 Pro, that's changing again. The phone sees the global debut of the Snapdragon 636 platform, which brings Qualcomm's semi-custom Kryo cores to the budget category. The Kryo cores used in the Snapdragon 636 are based on ARM's A73 core, which is one of the fastest performance cores on the market today.

The Redmi Note 5 Pro is the spiritual successor to the Redmi Note 3, and unlike last year, you're getting great performance as well as long-lasting battery life. Honestly, the Redmi Note 5 Pro sets a new benchmark for the budget segment in terms of performance.

Then there's the battery side of things. The Mi A1 delivers astonishingly great battery life even though its battery size at 3080mAh isn't quite as large as what you get on the Redmi Note phones, but it doesn't come close to the Redmi Note 5 Pro. Like last year's Redmi Note 4, the Redmi Note 5 Pro is a battery monster, delivering at least two days' worth of usage from its 4000mAh battery.

One of the major new features in the Redmi Note 5 Pro is the camera, and while the Mi A1 had one of the better cameras in the budget segment last year, it's not as good as what Xiaomi has managed to achieve this year.

The Redmi Note 5 Pro consistently takes better pictures, both in daylight as well as low-light conditions. It's under artificial or low lighting where the camera truly shines, as this was the one area where budget phones traditionally struggled. Even shots taken in daylight have much more detail and dynamic range on the Redmi Note 5 Pro.

Where the Mi A1 wins

There's no doubt that Xiaomi makes great hardware; but as good as the hardware is, the software side of things haven't evolved quite as much over the years. That was why the Mi A1 was a welcome move. The phone offers the best of both worlds — you get Xiaomi's gorgeous design and build quality, coupled with pure Android and the guarantee of fast updates.

Sure, Xiaomi put a lot of effort into customizing MIUI for the Indian market, and there are a few features in the ROM that would've been a great addition to Android One. The dialer in pure Android, for instance, is barebones to say the least, as is Android Messages. At least when it comes to stock apps, Xiaomi does a much better job.

The Mi A1 demolishes the Redmi Note 5 Pro when it comes to software.

That said, MIUI is no match for Android One when it comes to the design aesthetic. MIUI over the years has ballooned into a ROM that's laden down with features, and while Xiaomi introduced much-needed optimizations in MIUI 9, we're long overdue a complete visual redesign.

The Mi A1 picked up the Oreo update at the start of the year, and Xiaomi is doing a decent job when it comes to rolling out security updates. In this area, it's a no-contest — the Android One-based Mi A1 absolutely muscles the Redmi Note 5 Pro when it comes to the software experience.

Which should you buy? Your call

At the end of the day, Xiaomi is in a win-win situation here — for the longest time, it's fans have been clamoring for a device with pure Android, and it has delivered just that in the Mi A1. The phone is ideal for those looking for an uncluttered software experience, and it has the best bits of MIUI thrown in for good measure in the Mi Camera as well as the Mi Remote app.

The Redmi Note 5 Pro, meanwhile, showcases the best that Xiaomi has to offer in the budget segment. There's no outright winner here, as both phones offer incredible value for money. If a clean software experience is what you're after, then the Mi A1 is ideal for you. If you want a phone with the best hardware available today and a class-leading camera, then the Redmi Note 5 Pro is the obvious choice.

If I had to choose, I'd go with the Mi A1 simply because it delivers the best software experience in this segment, and it's guaranteed to be one of the first phones to receive platform and security updates. That said, I do like the Redmi Note 5 Pro's camera better, and the hardware on offer with the device is just staggering. An Android One variant of the Redmi Note 5 Pro would be the perfect device for this segment.

Simply put, these are two of the best budget phones available today.

The Redmi Note 5 Pro also comes with an 18:9 panel with configurable on-screen navigation keys, and the variant with 6GB of RAM and 64GB of storage should be more than adequate for even the most hardcore users. Then there's the dual camera at the back, which has the potential to be one of the best in this segment for a long time. The front 20MP camera is no slouch either, and if you're one to take a lot of selfies, there's Beautify 4.0 and a software-assisted portrait mode.

Sure, MIUI is in need of a visual overhaul, but Xiaomi at least optimized the ROM in MIUI 9, and things aren't as slow as they used to be. The upside with the Redmi Note 5 Pro is the sheer performance on offer, and it's unlikely we'll see a phone come close to matching that in this category anytime soon. The fact that it costs the same as the Mi A1 at ₹13,999 is a masterstroke.

If you're looking for even more grunt, then the 6GB version of the Redmi Note 5 Pro is all set to make its debut in the country shortly.
