The Xperia Z is a big old fatty in comparison, coming it at a slightly bigger 7.9mm thick (139 x 71 x 7.9mm all round), while weighing a much more substantial 146g. Huawei's Ascend D2 is the real heavyweight in this round-up, coming in at chunky 9.4mm thick (140 x 71 x 9.4 mm). But if it's kind to our wallets, we're less likely to mind the weight.
Xperia Z vs Ascend D2 vs ZTE Grand S: Battery
Big screens require big batteries to keep them alive. Any shortage in this department and you've just committed to spending £36 a month for the next two years on a constant source of disappointment.
In terms of physical capacity, the Xperia Z offers a 2330mAh battery, the Grand S is rated at a low-end 1780mAh that's a surprisingly small choice given the size and power of the phone, while the Huawei contains an enormous 3,000mAh unit.
These will give varying levels of performance when in use, and Sony's making a big deal about the power-saving hibernation features within the Xperia Z, but on paper you'd have to choose the fatter Huawei for its potential uptime if you demand a long-life mobile.
Xperia Z vs Ascend D2 vs ZTE Grand S: Early verdict
There's something to recommend in all three, is the sad, fence-sitting conclusion here. The Xperia Z will feature Sony's incredibly packed and versatile custom user interface, although the Android hardcore will moan that it's not appearing with Android 4.2 as its launch OS. It'll be a great piece of hardware, though.
ZTE's Grand S offers the slimmest chassis and is by far the lightest and most pocketable of the three big-screen phones, but the compromise here is the poor 1780mAh battery - surely not enough given the power demands of its quad-core chipset and enormous display.
The key offering from Huawei is its enormous battery, with that 3,000mAh cell set to be one of the otherwise chunky and otherwise unremarkable phone's biggest selling points. It's the fattest and heaviest of the trio, but with nearly double the battery power of the ZTE model, it'll surely keep you amused the longest.
In summary, we'll have one of each, please.
