This new rugged phone has a 16,000mAh battery, thermal imaging, and a slimmer design than you might expect

• The Oukitel WP70 Ultra is a new rugged phone with a 16,000mAh battery
• It also has a night vision camera and thermal imaging
• Oukitel claims it's the “slimmest 16,000mAh rugged smartphone”

Oukitel has landed at IFA 2026 with two new phones, the most intriguing of which is probably the WP70 Ultra — the “slimmest 16,000mAh rugged smartphone.” So, yes, this thing has a 16,000mAh battery, dwarfing most other battery beasts like the 10,000mAh Xiaomi Redmi Note 17 Pro Max.

Compared to a typical smartphone, this battery capacity is even more impressive — the iPhone 17 Pro Max, for example, has a 5,088mAh battery in its eSIM-only configuration, and a lower capacity for versions with physical SIM card slots. Similarly, the Samsung Galaxy S26 Ultra has a 5,000mAh battery. So the Oukitel WP70 Ultra has over triple the capacity.

It also charges at a decent 66W, though despite the company’s claims of a relatively slim design — and the use of a dense silicon-carbon battery to keep the size down — this is still a very chunky device at 16.4mm thick.

Still, considering the battery capacity and that this is a rugged phone with a tough outer shell, it doesn’t sound too bad.

Built for challenging environments

The Oukitel WP70 Ultra has all sorts of other tech packed into it too, including pro-grade thermal imaging to help you “identify risks and locate heat sources,” even in total darkness or smoke and fog.

Other specs include a 6.78-inch 120Hz AMOLED screen, a mid-range MediaTek Dimensity 7200 chipset, a 108MP main camera, a 64MP night vision camera, and Android 16.

Pricing and availability are yet to be confirmed, but even with such a massive battery, this is sure to be a niche device — aimed more at people whose work or hobbies put them in challenging outdoor environments than at the average smartphone user.

But if you want a battery that can last for days paired with a durable device that sports night vision and thermal imaging, then the Oukitel WP70 Ultra could be one of the best rugged phones on the market.
