Battery life is always a big consideration when buying a new phone, and most big-name smartphones manage to pack in cells good enough to get you through a day or two.
And while the iPhone 7's 1,960mAh battery wasn't quite up to par this year, a new Chinese smartphone takes things perhaps slightly too far in the other direction.
The YAAO 6000 is a smartphone, likely to be released in China only, that comes packing a whopping 10,900mAh battery (via PhoneArena).

You might be wondering just how big a phone has to be to accomodate such a hefty battery, but the official renders don't seem to be too much larger than a standard device – though, there's no photos of the YAAO 6000 yet.
What's more, the battery itself seems to be removable, which means users should be able to swap in a spare – though quite why you'd need anything more than the 10,900mAh cell remains unclear.
The phone is up for pre-sale on Jingdong for around $220 (about £176), and we're not expecting it to make it to any markets outside China.
It comes with some rather uninspiring specs too, including 1GB of RAM, 16GB of expandable memory, and a 5.5-inch 720 x 1,280 display.
Running the whole show is a MediaTek MT6735 quad-core SoC, and in terms of cameras, the rear-facing setup is a 13-megapixel affair, while the front-facing shooter is 5-megapixels.
