Oukitel WP21 Review: Ultimate Flagship With Premium 6nm Chipset and 20MP Night Vision Camera

Oukitel has announced the launch of its WP21 smartphone, which among other things is a rugged phone that won’t leave you with a low battery. This well-made smartphone packs a 9,800mAh power unit inside and it runs on a 4G chipset – the 6nm MediaTek Helio G99. It comes with 66W charging support for charging large battery. The Oukitel WP21 not only continues this tradition with a high-capacity battery capable of fast charging but also introduces a unique look to the series. The dual-screen setup allows the phone to simulate having a watch on the back.

Are you interested in a rugged smartphone with a dual screen? The purpose of this article is to present a detailed Oukitel WP21 review to understand the various specifications and qualities of a true professional. This may be what you like, so let’s get to know it thoroughly.

Massive Battery & Ultra Fast Charging

The huge battery immediately gets your attention. Oukitel says it can stand by for 115 hours or watch videos effectively for 12 hours on a single charge. By comparison, in our own battery tests, the Samsung Galaxy S22 Ultra’s 5,000 mAh capacity lasted for more than 13 hours of normal use and about 7 hours of video streaming. Using Type-C and 66W Quick Charge it basically takes 2 hours to fill up the 9800mAh, which is very fast and I can say the battery is very good compared to anything else on a rugged phone.

In addition, WP21 also supports recharge battery-powered electronics when you are on the go, which can come in handy when your smartphone, smartwatch, TWS Earphones, and other Switch devices are running low on power, allowing you to use it as a rechargeable battery at any time.

64MP Triple Cameras

The phone also comes with a triple camera setup, including

  • 64MP primary camera with Sony IMX686 sensor
  • 20 MP night vision camera with Sony IMX350 sensor
  • 2 MP macro camera
  • 16 MP front-facing selfie camera

The IMX686 sensor supports pixel merging, so we can expect sharper photos with it. It’s also capable of recording 4K video at 60 FPS, although that’s not specified on the WP21’s spec sheet.

It’s worth noting that the WP21 comes with a dedicated night vision camera. While this is not the first smartphone to come with night vision, it is impressive that Oukitel has equipped this phone with a dedicated handset.

Dual Screen Design

The Oukitel WP21 is equipped with dual screens. Its main display is a 6.78-inch panel with FHD+ resolution and 120Hz refresh rate. The second display, located on its back, is a small, always-on screen that displays important information such as the time of day, notifications, music controls, and more. It also doubles as a camera viewfinder, allowing you to take selfies with the rear camera.

120HZ Refresh Rate Display

The WP21 marks the entry of Oukitel’s flagship range into the high-screen refresh rate cell phone segment in India. The smartphones come with 120Hz refresh rate displays. They come with a 6.78-inch FHD+ AMOLED panel and MediaTek Helio G99 under the hood. Add to that a whopping 12GB of RAM and 256GB of onboard storage.

It’s not just gaming phones, even mainstream smartphones today are flaunting high screen refresh rates that are thought to provide butter-smooth scrolling, animations, and transitions. The list of phones with 120Hz displays is growing and will increasingly appear in the next generation.

Ruggedness Design

The Oukitel WP21 is dust and water-resistant to IP68 and IP69K ratings. In addition, the device is MIL-STD-810H certified, allowing it to operate flawlessly in a variety of extreme weather conditions.

The IP69K rating means it is fully dust and water-resistant when submerged in 5 feet of water, and the addition of IP69K proves it can also withstand high-pressure water flow. Oukitel also lists it as drop-proof, claiming that accidental drops from heights of up to 1.5 m (~5 ft) will not damage the device.


Oukitel seems to have a specific audience for its line of rugged phones. These people want a device that feels modern but can withstand extreme conditions.

The WP21 may aim to offer a unique-looking phone to the audience. The dual-screen setup is an important step in making rugged phones stand out in a world where cool-looking (but not so rugged) foldable phones are slowly taking over.
