I bought Xiaomi Mi 3 on August 2014. Since then I am using it and it has not given any problems till now.
First impressions of the Xiaomi Mi3 suggest it’s ‘just’ a high-end plastic phone – again, in the Nokia mould. But it’s not. This is a magnesium alloy phone, and it is one of the first to use magnesium as its outer layer rather an inner casing. To be specific, the outer part of the Mi3 is a magnesium-aluminium alloy with three layers of graphite on top.
There’s no microSD memory card slot, and with just 16GB of storage in the standard version, you only have about 11GB to use for music, pictures and such.
The Xiaomi Mi3 is a millimetre wider than the Galaxy S5, and that phone has a slightly larger screen. However, as the Xiaomi Mi3 is just 8.1mm thick and otherwise pretty sound ergonomically, it’s really a design choice rather than a design issue.
The one other obvious missing bit is an IR transmitter, although it still has NFC, GPS, Wi-Fi and an MHL-compliant USB port.
The Xiaomi Mi3 has a display that can compete with its much better-known rivals. It’s a 5-inch LCD screen of 1080p resolution.
The Xiaomi Mi3 uses the Snapdragon 800 processor and 2GB of RAM. It’s a quad-core 2.3GHz chip. Each of these specs is slightly off the very top rung in phones, but the difference is largely inconsequential in terms of what it’ll mean in real life for most people.
It uses the Sony IMX135 sensor, a 13-megapixel 1/3.06-inch chip. Despite being pretty thin, the Xiaomi Mi3 still packs in a pretty decent 3, 050mAh battery.
Should I buy the Xiaomi Mi3?
Absolutely Yes, you should go for it.
