Design and Features
The Sony Xperia M4 Aqua has a sleek design that's hard to tell apart from the Xperia Z3 at first glance. It has a glass front and back with rounded edges, and a minimalist Sony branding.
The phone's waterproof feature is a major plus, allowing it to survive a spilled drink or an accidental dip in the bathroom. It even has a physical camera button on the outside that lets you take photos underwater.
The phone's 5-inch display has a 1,280x720-pixel resolution, which is not the highest, but it seemed adequately crisp and bright in my hands. The battery life is expected to last for two days of regular use, which is a big ask for any smartphone.

Sony reckons the battery will be able to keep going for two days of regular use, which is a big ask for any smartphone, but I found the battery life on the Z3 particularly good, so I'm looking forward to seeing what the M4 can achieve.
You'll find a Micro-USB charging port on the phone, which is now waterproof, meaning you no longer need a rubberised port over it to keep the water out.
