Now Sony has officially revealed the full spec sheet, pricing and more for its new flagship phone. Read on to find out how it's bringing the fight to the likes of the Samsung Galaxy S4, LG G2 and HTC One and iPhone 5.
It's an Xperia through and through
The Xperia Z1 looks almost identical to the Xperia Z, with a sleek rectangular body slathered in glass; the same distinctive aluminium power button and silver port flaps are also present and correct. However the Z1 is actually more water resistant then its predecessor, boasting IP55 and IP58 levels of protection. You can take the Z1 into the shower with you every morning if you wish.
It's 1080p, but a better version of 1080p
Like the Xperia Z the Sony Xperia Z1 sports a 5in 1080p display, but now it benefits from the same improved screen technology – Triluminous display and X-Reality – that can be found in the Xperia Z Ultra. From our hands-on time with the Z1, we're impressed with its wide colour gamut, its brightness and its contrast but we'll have to wait for a full review before we can see how it squares off against the HTC One, our current screen favourite.
Many, many megapixels
Here's where things get really interesting. The Xperia Z1 boasts a 20.7MP Exmor S sensor with a F2.0 'G' lens and LED flash.
We're itching to take it out in the field and give it a proper runthrough, but from our hands-on time at IFA we're impressed with the camera app and the apps that run within it: Social Live lets you livestream video to your Facebook page and Info-eye works in a similar way to Google Goggles. There's also Timeshift Burst, which snaps 60 frames in a row and lets you pick the best; it's constantly buffering 30 frames in advance of you pressing the shutter, which makes you less likely to miss something.
It's a processing powerhouse
The Sony Xperia Z1 has 2GB of RAM and the same 2.2GHz quad-core Qualcomm Snapdragon 800 processor as the Xperia Z Ultra and LG G2. That makes it one of the most powerful phones in the world, both in benchmarks and real-life use. If our review of the Xperia Z Ultra is anything to go by, then we expect nothing but the slickest performance in everything from games to multitasking from the Xperia Z1.
It has a whopping battery
As for other specs, the Z1 offers NFC, 16GB of expandable storage (a microSD slot supports up to 64GB cards) along with a large 3,000mAh battery to keep everything running for at least a day of use. Sony's familiar power saving features are also baked into Android, promising to squeeze out every bit of juice by turning off updates and connections when the device is idle.
When's it out?
Sony has announced that the Xperia Z1 will go on sale in September, so expect it to be available any day now. It'll be priced at £600 SIM-free.
