Oukitel WP21 Review: The Ultimate Rugged Smartphone with Impressive Features

The OUKITEL WP21, a rugged smartphone with impressive features and specifications, is.. From its dual SIM 4G global network capability to its powerful 9800mAh battery and 66W fast charging, this phone is designed to withstand harsh environments and provide a reliable performance. In this review, I will share my personal experience with the WP21 and give my final thoughts on its overall performance.

I have been using the WP21 for a few weeks now and I must say, I am impressed with its durability and long-lasting battery life. The phone has a solid build and feels sturdy in my hands, although it is slightly thicker and heavier compared to average smartphones. However, the extra weight is justified by the impressive 9800mAh battery, which can easily last for days on a single charge.

The 6.78-inch FHD+ front screen with a 120Hz refresh rate delivers a smooth and immersive viewing experience. I particularly enjoyed playing games on this device, as the high refresh rate made the gameplay more realistic and enjoyable. The 64MP AI main camera and 20MP front camera capture clear and detailed photos, and the 20MP night vision camera is a standout feature, providing excellent image quality even in pitch-dark environments.

One aspect that slightly disappointed me was the occasional freezing and locking up of the phone. Although it didn’t happen frequently, it was frustrating when it occurred during important tasks or while watching videos. Additionally, I found it challenging to find instructions on certain features, such as saving photos/videos to the SD card and turning on thermal imaging.
