The Sony Xperia M4 Aqua and Xiaomi Mi 4i are two smartphones that have been released last year and today we’re going to compare them. So, if you’re undecided which one to buy, then it’s worth checking out their specs and features, which we’ll guarantee that they’ll draw your attention.


The Sony Xperia M4 Aqua measures 145.5×72.6×7.3mm and weights 136 grams. It has that specific design found on other Xperia devices, featuring a glass back with rubber bumpers (corners) and the interior is protected against dust and water. On the other hand, the Xiaomi Mi 4i is thicker and lighter, as it measures 138.1×69.6×7.8mm and weights 130 grams, but its design is simpler and the back is made of plastic.


Both phones have a 5-inch IPC LCD screen, but the Sony Xperia M4 Aqua supports a resolution of 1280×720 pixels at 294 ppi and it’s protected by a scratch-resistant glass, while the Xiaomi Mi 4i offers a higher resolution of 1920×1080 pixels at 441 ppi and it’s protected by a Corning scratch-resistant glass.

Processors, Graphics Cards & RAM

The two devices have almost an identical configuration, as they come with a Qualcomm MSM8939 Snapdragon 615 chipset with two quad core processors, an Adreno 405 GPU and 2GB of RAM, but the Xperia M4 Aqua has its quad-core Cortex A53 processor clocked at 1.5GHz, while Xiaomi Mi 4i has set four cores at a clock speed of 1.7GHz.


The Sony Xperia M4 Aqua has been released in two internal storage variants of 8GB and 16GB, which you can expand up to 128GB using a microSD card. The Xiaomi Mi 4i can be purchased with an internal storage of 16GB and 32GB, but keep in mind that you will not be able to expand it, as the device doesn’t feature a card slot for storage expansion.


Both devices feature similar cameras, as follows:

– a primary camera of 13MP with autofocus, LED flash, geo-tagging, touch focus, panorama, HDR, face detection (found on the rear side);
– a secondary camera of 5MP (located on the front side).


Both handsets come with non-removable batteries, but the Xperia M4 Aqua has a less powerful battery of 2400 mAh which is easily outperformed by the 3120 mAh battery of the Xiaomi Mi 4i.
