Verdict

The Sony Xperia M4 Aqua (8GB internal storage model, which is paired with 2GB RAM rather than 4GB) is a mid-range Android smartphone featuring a 5-inch HD IPS display (1280x720 pixels), powered by a 64-bit octa-core Qualcomm Snapdragon 615 processor. Its primary strengths include an attractive design that mimics the flagship Z series, an IP65/IP68 waterproof and dust-resistant rating for durability, and a decent 13MP rear camera and 5MP wide-angle front camera. Key downsides, however, are the extremely limited usable internal storage (often less than 2GB out of the advertised 8GB due to bloatware and system files), a camera that is slow to focus, and a non-removable 2400mAh battery with slow charging times.
