Getting the best smartphone features doesn't necessarily mean you need to have a big phone; Sony's new 4.2-inch Xperia Z3 Compact is a mini marvel that's every inch a flagship.

Xperia Z3 Compact has all of the details that make Xperia smartphones the best on the market – including the highest level of waterproofing and dustproofing, Sony's enhanced camera technology and applications, up to two-day battery life, the best audio quality and the brand new PS4 Remote Play feature.

And it's stylish, too, its smart rounded frame finished off with tempered glass panels either side. It feels great in the hand - the only smartphone to truly deliver an uncompromised user experience and performance in such a compact design.

Perfect for one-handed use, the handset is just 8.6mm thick and weighs in at a lightweight 129g, meaning it certainly won't weigh heavy in a trouser or skirt pocket. And you can find the phone colour to suit you –Xperia Z3 Compact's unique range of finishes include orange and green, in addition to the classic white and black.

As you'd expect from a premium smartphone from Sony, Xperia Z3 features full waterproofing (IP 65/68 rated). That's some serious life-proofing – you can answer a call in the rain or even take some video in the swimming pool.

And you don't need to stop at Full HD, either; Xperia Z3 Compact enables you to record in super-clear 4K via a camera app. So you're able to have future-proof video at four times the pixels of Full HD.

For those most important memories, record clips in super-clear 4K resolution. Plus, the advanced video mode on Xperia Z3 and Xperia Z3 Compact means you can pause and resume filming, so you can be sure to capture the perfect moment in one file.

Power is at the heart of Xperia Z3 Compact. It packs serious power thanks to the latest-generation Qualcomm's Snapdragon 801 processor. It's a 2.5 GHz quad-core CPU that works in tandem with an integrated, fast 4G LTE modem.

Battery life is no issue for Xperia Z3 Compact – with a potential two-day usability thanks to Sony's Battery STAMINA Mode, which turns off background functions when you're not using them to help extend your battery life. That means you won't be running out of juice when you need to send that crucial email from your Gmail account, or take that memorable photo of your friends.

Talking of photos, you'd expect a premium Sony smartphone to be superb for taking great images and Xperia Z3 Compact is no different. Drawing on Sony's Cyber-shot and Handycam technologies, you'll be able to take superior images with the 20.7 Megapixel camera thanks to the 1/2.3-inch ExmorRS for mobile sensor and BIONZ for mobile processing engine working together to give you sharp and vivid photos and videos.

There are also a bunch of great new camera apps to download, including Face In, that uses both cameras simultaneously to place your face in images to remind you of events or when you visited a particular place. Movie creator is a terrific app that enables you to create videos on-the-fly by importing other videos from your handset and combining them with photos and effects. The revolutionary Multi-camera also enables you to connect your Xperia Z3 Compact to up to three other compatible Xperia devices so you can record the same event from multiple angles.

If you often take images in low light conditions, such as when you're out in the evening, you'll find no better smartphone than Xperia Z3 Compact. Thanks to the world's first ISO 12800 sensitivity in a smartphone, you'll still get brilliant images.

And for videos, Intelligent Active Mode uses Sony's SteadyShot tech to compensate for your movements, so wherever you're shooting you'll have less shaky videos as a result, also making panning smoother. It does this by analysing dozens of backwards and forward frames and can predict how you might move next.

If you're a PlayStation 4 gamer, Sony's new Xperia line is definitely for you – if someone is using your TV, you're able to connect to and play your PS4 games on your Xperia Z3 Compact. With the separately available GCM10 Game Control Mount, you can connect your Xperia smartphone to your PS4 via your Wi-Fi and use the DUALSHOCK 4 Wireless Controller to continue playing games.

If music quality is important to you, Xperia Z3 Compact features the best sound quality on the market thanks to High-Resolution Audio – get the most from it by listening with Hi-Res Audio headphones such as Sony's new MDR-1A range.
