Here is a phone that gives you the best of both worlds. Xiaomi’s first Android One device, the Xiaomi Mi A1, looks to offer everything you’d want in your ideal phone. Understated design, stock Android and excellent performance at an affordable price point. With such lofty promises on paper, it would be interesting to see how the device performs in real life.

The Xiaomi Mi A1 is an unassuming-looking phone with its metal unibody design cut out of a single aluminum block. There are no flashy elements on the exterior except the chrome accents around the camera lens, fingerprint sensor, and Mi logo at the back. The design is undoubtedly a welcome change from Xiaomi’s signature Redmi series, bold and loud designs.

Display Screen:

5.5-inch, IPS LCD Resolution: 1920 x 1080 pixels ppi density: 403ppi pixel format: RGB Features: 2.5D curved glassOn the front of the Mi A1 is a 5.5-inch Full HD display with an aspect ratio of 18:9, and like most Xiaomi devices this year, no home button. The 2048 x 1080 pixel resolution is sharp and legible under bright sunlight.

However, the contrast ratio isn’t as good as some of the other LCD screens out there, which makes for slightly pale blacks in comparison. Also, the viewing angles aren’t as great either. In comparison to an AMOLED panel, there is a significant difference in the contrast of blacks and whites. That isn’t necessarily a bad thing though—most users would find this screen perfectly acceptable for its price range.

Design & Build Quality:

The body of the phone is well-machined and has a very premium look to it. The edges are nicely rounded off, making for comfortable one-handed usage. Weighing 165g, the phone feels just right in the hand—not too heavy not too light. The metal unibody design looks and feels very durable, plus the phone is splash resistant. There are antenna lines on the top and bottom of the chassis that help to break up what would otherwise be a very monotonous rear panel.

Camera Details:

The Xiaomi Mi A1 packs a dual camera set-up on the back with two 12MP sensors, one for color and one for luminance. On the front is a 5MP selfie shooter with an LED flash. The primary rear sensor can shoot up to 2160p video at 30fps whereas the secondary sensor only shoots 1080p video footage at 30fps.

The camera app on the Xiaomi Mi A1 offers a host of features, including manual mode that lets you modify parameters like white balance and ISO for more granular control over your shots. There is also an AI portrait mode that blurs out backgrounds to produce DSLR-quality bokeh effects even though this is just a single camera unit. There’s also an expert mode that lets you tinker with the finer details like shutter speed, aperture, and ISO.


On the performance front, the Xiaomi Mi A1 packs a Qualcomm Snapdragon 625 chipset with an octa-core 2GHz CPU and Adreno 506 GPU. There’s 4GB of RAM and 64GB of storage that can be expanded by up to 128GB via a microSD card slot. The phone runs Android 7.1.2 Nougat with Xiaomi’s MIUI 9.5 on top, which is very customisable thanks to the plethora of themes available in the Theme store.

You can choose from three different modes depending on how you want your phone to perform—performance mode maximises battery life whereas battery saver reduces performance so as to improve standby time. There are also features like reading mode that filters out blue light to reduce eye strain and an SD card cleaner to clear up space.

Battery performance:

The Xiaomi Mi A1 comes with a 3,080mAh battery pack that easily lasted us a full day of use. We were able to get around 4 hours and 45 minutes of screen-on time on a single charge with the phone’s performance mode enabled. In our HD video loop test, the Mi A1 lasted for 13 hours and 35 minutes, which is quite impressive given the phone’s price. (Continued…)

(… )The standard power saving mode reduces the processing speed to improve battery life. This helps you get more juice out of your device when you’re low on battery. There are also features like reading mode that filters out blue light to reduce eye strain and an SD card cleaner to clear up space.

(… )The phone also supports Qualcomm’s Quick Charge 3.0 fast charging technology, which can charge the battery from 0 to 50 percent in just 30 minutes. It would have been nice if Xiaomi included a fast charger inside the retail box though.
