    Take your phone for a dip

    The Xperia M4 Aqua is dustproof and waterproof up to 1.5m, for 30 minutes. So whether you want to watch a movie in the bath, or take pictures at the pool, the M4 Aqua is ready to go. It comes with a 13 megapixel main camera, packed with the best in Sony camera technology. The Superior Auto feature recognises 52 different scenarios and then automatically changes your camera settings to get the best picture possible.

    Make video calls and take selfies on the front facing camera

    As well as the main camera, the Xperia M4 Aqua has a 5 megapixel, wide angle front camera. So whether you're keeping in touch with friends and family on a video call, or taking a group selfie, you can fit more into your shot. And with auto scene recognition, your phone adapts to your surroundings so you'll get clear, professional looking picture.

    Go for up to two days with the long lasting battery

    Some days you just can't get off your phone, and luckily the M4 Aqua is well equipped to deal with your busy schedule. It has a battery that lasts two days so you'll never have to worry about your phone running out of power when you need it the most. And just to make sure you can go for even longer, you can activate Battery STAMINA Mode.

    Get to your apps in an instant

    If you want an easy way to find the apps you use the most, switch on the Simple Home screen. The M4 Aqua comes with a big, bright 5 inch HD display, so you can see all your apps clearly and watch movies and entertainment in great detail. And IPS technology means you get a clear view at any angle. Plus Face Unlock uses facial recognition to make sure your phone will always be secure.

    Why doesn't this phone come with a charger?

    O2 is working to try and reduce waste. And as 70% of people already have a USB charger at home, we've decided to not include one with your phone. If you do need a charger, add one at a discounted price - you can do this after choosing your tariff. O2 does not make money from selling the charger separately.
