The OUKITEL U7 Plus was introduced as one of the most affordable Android smartphones in its category, offering basic functionality at an entry-level price. While the hardware is limited by today’s standards, it still fulfills essential communication needs. In this article, we’ll provide a concise product review and a clear battery replacement guide for the U7 Plus, along with information on where to purchase a compatible replacement battery.
Product Overview
The OUKITEL U7 Plus is powered by a MediaTek MT6737 quad-core processor clocked at 1.3 GHz, with 2GB RAM and 16GB of internal storage (expandable via microSD). Its performance is modest, suitable for basic tasks such as phone calls, messaging, web browsing, and social networking apps. The device runs on Android 6.0 Marshmallow with a near-stock interface, which helps maintain responsiveness despite the limited hardware.
The display is a 5.5-inch 1280×720 IPS panel, offering a pixel density of approximately 267 PPI. Colors appear cool and the viewing angles are narrow, but brightness is acceptable for indoor use. The body is made of plastic with a removable back cover, which adds to the accessibility but contributes to a relatively bulky form factor, weighing approximately 200 grams.
Camera performance is minimal. The rear camera is 8MP (interpolated to 13MP), while the front camera is 2MP (interpolated to 5MP). In good lighting conditions, photos are usable, but image noise becomes evident in low-light scenarios. The fingerprint sensor located on the rear side is functional but slow, with an estimated accuracy of 80%.
Connectivity includes GSM, WCDMA, and LTE support on several international bands, but U.S. users are limited to 2G/3G networks. The speaker delivers limited audio output and lacks bass, and the headphone audio quality depends heavily on external hardware.
The major limitation of the OUKITEL U7 Plus is its 2500mAh removable battery, which typically lasts one day under moderate use. Charging is relatively slow, taking approximately 3.5 hours with the original charger. However, because the battery is removable, replacement is straightforward and inexpensive.
