A report from PhoneArena may have lifted the lid on the innards of the Sony Xperia Z5.
Top of the spec list is the brand new Qualcomm Snapdragon 820 SoC CPU, which in tests provided moderate performance boosts over its predecessor the 810, but failed to match up to the Exynos 7420 found in the Samsung Galaxy S6. This raw processing horsepower will be backed up by 4GB of RAM.
Next comes battery life: the Xperia Z5 is said to hold a gargantuan 4500mAh. To put that in context, the LG G4 features a 3000mAh battery and the Samsung Galaxy S6 a 2550mAh battery. Size isn't everything, and dependent on the power usage of the other components and factors like degradation, the running time improvements might not be massive, but they should definitely be notable.
Last but not least comes the camera, which the report indicates will be the massive 21MP Sony Exmor RS, which is capable of recording 4K video. This would put the Xperia Z5 almost at the top of the pile for camera megapixels. The camera inside the iPhone 6 is less than half as powerful (on paper, at least).
Rumour indicates that Sony will be unveiling the handset in Japan in September. We hope the end product turns out to be as intimidating as these specs would have us believe, especially as the recently-launced Xperia Z3+ doesn't really feel like a giant or innovative leap over its predecessor.
