Sony's Z3 Compact is a smaller and cheaper version of its flagship smartphone, but without all the usual downgrades. Here's our Sony Xperia Z3 Compact video review. (Also see our full Sony Xperia Z3 Compact review)

This is in essence the Xperia Z3 mini and, although the full-size version will set you back more than £500, the Compact is available for just £350, which is a significant saving. Typically, this would mean inferior design and specs, but Sony has done a great job of not compromising here. Also see: Best smartphones 2014 

It's not a massive amount but the Xperia Z3 Compact is slimmer and lighter than its predecessor. It looks stylish, feels snug in the hand and has excellent build quality, too. Also see: Best Android phones 2014  

As we now expect from the Z range, the phone is dust and water-resistant and to a new high rating of IP68. That does mean flaps apart from the headphone port but it's the price you pay and handily hides ugly ports when shut. Also see: Sony Xperia Z3 review 

Despite being the same overall size, Sony has squeezed a large screen in. It's now 4.6in compared to 4.3in of the Z1 Compact. The resolution is still 720p meaning a small drop in pixel density. It's one of the only specs which is lower than the Z3. 

Other than less memory at 2 GB, the Z3 Compact matches it bigger brother on core hardware including processor, storage and camera. We found benchmark results decent, particularly in the graphics department, and the battery life of the Z3 Compact is immense. 

It might not have wireless charging but even without Stamina mode switched on, we got 2-3 days from the phone. Sometimes having a lower res screen pays off. 

It's good to see 11ac Wi-Fi, Bluetooth 4.0, NFC and 4G LTE support. However, you'll need to look elsewhere if you want things like wireless charging, an IR blaster, fingerprint scanner or other built-in gadgets. 

Although it's missing things you can find on rivals, the Z3 Compact has a couple of unique tricks up its sleeve.  

The first is PS4 Remote Play which will launch in November, allowing users to play PS4 games on the phone over the same network as the console with a Dual Shock controller.  

The second is support for High-Res audio which we've seen in phones like the LG G3 but the Z3 Compact can play DSD files which is a first for a smartphone. It can also upscale your existing tracks. 

Sony has stuck with the same 20.7 Mp camera as previously and we can see why with excellent quality on offer. New additions include a 28mm wide angle lens, 12800 ISO and some new camera apps including 4K video recording. 

The Xperia Z3 Compact comes with Android 4.4.4 KitKat and will be updated to Android 5.0 Lollipop. Sony's user interface remains close to stock Android with the usual style tweaks which are nothing drastic. The firm is sticking to its formula which will please existing fans. 

There are only small changes like bigger app icons and the optional ability to double tap the screen to switch it on. A number of apps are pre-loaded but you can uninstall most if you don't need them. 

With almost everything which the full-size Z3 offers at a lower price, the Xperia Z3 Compact is a great buy and not only the best mini device we've seen but one of the best smartphones around. We award four and a half stars and our Recommended award.
