Huawei's pitching its biggest Mate phone to take on Nintendo and Samsung in one hit.

There had been plenty of leaks around Huawei's Mate 20 and Mate 20 Pro prior to their launch today, but Huawei still had a few surprises in store, including a Porsche Design phone and a super-sized variant, the Huawei Mate 20 X.

It'll feature a 7.2-inch 2,244x1,080 OLED display. Like the other Mate 20 phones, it'll feature the Kirin 980 processor, but that extra space gives Huawei more space to pack in batteries, with an impressive 5,000mAh battery on board. It uses a vapour cooling chamber with a graphene film coating to manage heat dissipation.

With a nod to Samsung's Galaxy Note9, the Huawei Mate 20 X will support a stylus, as well as a gamepad, with Huawei specifically calling out Nintendo's Switch as a competitor.

There's no word yet on Australian availability or pricing, though, so if you're keen you may need to import one. At the launch, pricing was listed at €899, or around $1,450 at current exchange rates.
