Xiaomi Mi A1 Hong Kong – A Feature-Rich Budget Smartphone

When you think about budget or midrange devices, one of the manufacturers that comes to mind is Chinese smartphone brand Xiaomi. Its phones are known to offer flagship-level aesthetics and specifications without being too costly. One of Xiaomi’s latest devices – the Xiaomi MI A1 does not only look and feels like a premium device, it also has powerful specifications and features which are rarely found in a budget smartphone. Here’s a rundown of its specifications and features.

Design and Build Quality

The Xiaomi Mi A1 takes its design cues from the OnePlus 5 and the Xiaomi Redmi Note 4. Its corners are more rounded which gives it a more polished finish than the Redmi Note 4, as well as making the phone more comfortable to hold in the hand. If you see the phone from the back, you might mistake it for the OnePlus 5.

The device does not only score an A for its looks as it is also very functional in terms of ergonomics. The Xiaomi Mi A1 is slender at 7.3mm, making it one of the slimmest smartphones around. At the same time, it is also lightweight at 165 grams. Being lightweight and svelte means that the phone can easily be fit into your pockets or a bag easily without being burdensome.


Display-wise, the Mi A1 is fitted with a 5.5-inch LCD display, a common size that can be seen in the mid-range Android smartphones today. The screen provides enough brightness for the phone to be used outdoors under the glaring sunlight without affecting its legibility. Colours are pretty decent and image quality is acceptable considering its budget price.


When software is concerned, the Xiaomi Mi A1 has an easy-to-use interface that is not cluttered with excessive amounts of bloatware and unnecessary apps. For users who prefer simplicity and minimalism, this phone will be a joy to use as it has an uncluttered interface that enables you to access your favourite apps easily.

Internal Hardware and Specs

Under its hood, the Mi A1 is equipped with the Qualcomm Snapdragon 625 octa-core processor which has been built on a 14nm manufacturing process, 4GB of RAM, 64GB of built-in internal storage, dual SIM support. This combination of specs enables the phone to deliver satisfactory performance that is sufficient for day to day usage. Considering that it is a budget smartphone, the Mi A1 does a good job handling more intensive tasks with minimal lags. For this reason, the Mi A1 remains as one of the best performing smartphones in the segment.


Xiaomi has decided to jump on the bandwagon for the Mi A1’s rear cameras, opting for a dual-camera setup. Under decent lighting conditions, the dual 12MP cameras on its rear take rich images with good levels of detail and colour saturation. Its 8MP front camera also shoots selfies that you will not feel embarrassed to upload onto your social media accounts.
