Xiaomi Mi A1 review

Display

The 5.5" IPS display of the Mi A1 is the same unit we saw on the Mi 5X, a pretty common choice in Xiaomi's smartphones. So, there are no surprises on the Mi A1, 1080p resolution on an RGB matrix.

Xiaomi promises 450 nits of maximum brightness for the Mi A1's screen and a contrast ratio of 1000:1. In our display test, we measured a maximum brightness of 550 nits and some pleasantly deep blacks. Overall, the Mi A1 has an excellent contrast ratio of 1570:1, way higher than the promised 1000:1. The color reproduction is passable, with an average DeltaE of 7 and somewhat punchy colors (especially the blue hues).

The sunlight legibility is okay but, overall, the Mi A1 suffers from washed-out colors in the sun. Other than that though, you will be able to comfortably see what's happening on the screen outdoors.

Battery life

The Xiaomi Mi A1 has a 3,080mAh battery, which is far from spectacular for a 5.5" device. Then again, the energy-efficient Snapdragon 625 helps it achieve some good battery endurance. The Mi A1 supports regular 5V/2A charging, which restores about 30% of a flat battery in 30 minutes.

Indeed, the Snapdragon 625 chip once again lived up to expectations. The Xiaomi Mi A1 scored an endurance rating of 87h. It did a fabulous job in all test scenarios - video playback, calls and web browsing, and demonstrated above average performance on standby thus matching the 5X.

Our endurance rating indicates how long a single battery charge will last you if you use the Xiaomi Mi A1 for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so our battery results are comparable across devices in the most common day-to-day tasks. 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.

Connectivity

The Xiaomi Mi A1 is a dual-SIM phone with LTE connectivity. Its LTE band coverage is far from impressive, but it supports the most common European bands. The SIM slot is a hybrid solution and allows you to replace one of the nanoSIMs with a microSD card.

There's also Wi-Fi ac, Bluetooth 4.2 is also available. For positioning, you get GPS, GLONASS and still Beidou.

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

Mi Remote app

The USB Type-C supports USB On-The-Go with the proper adapter in case you need to access some external storage or use a USB accessory.

There is no FM radio on the Mi A1, in contrast with the Mi 5X model. Or at least that's what we thought. Apparently, the FM chip is there and you can play FM radio from the test option in the service menu by dialing *#*#64663#*#*. The Google suite doesn't include an FM radio app and we couldn't find one in the Play Store that works on the Mi A1 either. Until you find an FM app that actually works with the hardware on the Mi A1, your only option to use the radio is via the service menu.
