Cubot KingKong Mini 4 Design, Build, and Controls

Cubot KingKong Mini 4 marries compact ergonomics with industrial resilience, featuring a reinforced unibody frame, tactile buttons, and a grippy, impact‑absorbing bezel that sits comfortably in the hand while resisting drops, dust, and moisture. The overall aesthetic balances functional minimalism with purposeful textures and color cues, signaling reliability while remaining unobtrusively pocketable. Cubot KingKong Mini 4 uses a combination of metal side frames, polycarbonate chassis, TPU for the top and bottom, including the padded corners, and tough plastic for the rear shell. The model is IP68 and IP69K-rated as well as MIL-STD-810H certified. The device can be soaked in water up to 5 meters in depth. The USB port and SIM tray are fortified against dust and water. Cubot KingKong Mini 4 is impressively compact and lightweight. With a width of 61 mm and a height of 128.7 mm, it is ideal for one-handed operation. The handset is 16.85 mm thick thanks to its rugged structure and 4700 mAh battery shrunk in a compact body. It also weighs 192 g only. The Black and Green version we're reviewing is inspired by the rugged shell of turtles, while the Black and Gray version draws inspiration from the graceful wings of butterflies, blending strength and elegance. The display occupies the biggest part of the front with 2 mm-thick side bezels, a 5mm top one, and a 10 mm-thick bottom bezel. The light and proximity sensors, as well as the LED notification light, are positioned in the left-hand half of the top bezel. The selfie camera resides in a punch hole in the top-center of the screen. Both virtual buttons and on-screen gestures are supported for system navigation. The rear shell features the turtle-inspired pattern with a triangular-shaped camera module, surrounded by an LED strip with oval corners and curved sides. This LED strip is the bright camping light of the KingKong Mini 4. The bottom houses the rear-mounted speaker. The Power and Volume buttons reside on the right frame, adjoined by a lanuard hole in the bottom right corner. The SIM tray and the customizable button are on the left frame, while the USB Type-C port is positioned on the bottom one.

Cubot KingKong Mini 4 Display

Cubot KingKong Mini 4 has a 4.7-inch IPS display with an HD+ resolution (720 x 1600 px) and a refresh rate of up to 90 Hz. We measured a maximum brightness of 633 cd/m² and a static contrast ratio of 1406:1. The display settings contain plenty of options - from the standard choice of themes, brightness settings, lock screen options, Night Light, and refresh rate, to Game Space, Video display enhancement, LED notification light settings, and a backlight power saving toggle. The CIE diagram of the KingKong Mini 4 screen demonstrates a non-exact coverage of the sRGB color space. It suggests that the blue, green, and red tones are duller, while the light green, yellow, and some magenta tones are overexposed. The display panel has a traditional vertical striped RGB subpixel arrangement.

The Home settings from the Customization picker are limited but do include the options to switch to an app-drawer launcher. The Settings app is monochrome, listing the different menus without any visual dividers for a cleaner and more streamlined look. The only non-typical menus are the Smart Assistant and the Smart Controls. The first contains Emergency Rescue, Screen Record, and Screenshot settings. The second comprises a Smart Wake Up and a Lift To Check Phone toggle, and Smart Motion toggles for easy call answering, alarm sound declining, and muting incoming calls. The list of pre-installed applications is also quite standard. It includes a dedicated Toolbox app for mirror, compass, flashlight, etc., and a dedicated Camping Light application.

Cubot KingKong Mini 4 Battery Life Tests

Cubot KingKong Mini 4 features a 4700 mAh battery with 10W charging. Below, we publish the results from our in-house battery life tests. The display of every device we test is calibrated to 200 cd/m². Battery-saving features are switched off where possible. The Cubot KingKong Mini 4 battery charged from 0% to 100% in 2 hours and 56 minutes with the provided cable and charger. The process develops slowly and steadily from the start until the battery regains 80% of its charge. That happens 1 hour and 55 minutes from the start. At that point, the process slows down and even more so after reaching 90% - it takes around 43 minutes to complete the last 10%. The voltage during charging behaves accordingly, without drastic ups and downs, and stabilizes at 4400 mV after 80% of the charge is reached, remaining at this level until the end. The battery temperature during charging starts at 26°C and gradually reaches its peak of 40°C after 1 hour and 15 minutes. It remains at this level for 20 minutes and starts decreasing, dropping to 27°C in the end. During our intensive browsing test with the screen's refresh rate set at 60Hz, the KingKong Mini 4 battery lasted for 11 hours and 7 minutes. The discharging process is slow for the first 40 minutes, then speeds up and maintains that speed until the end. The battery temperature starts at 25°C, reaches 34°C in 1 hour, and holds a 34-36°C level until the end. The video playing battery life test uses a 1080p video at 30 fps with a ~20Mbps rate. Our review unit's score is 15 hours and 23 minutes. The discharging process is slow for the first 1 hour, then it gains speed and maintains it until the end. The battery temperature starts at 27°C, reaches 30-31°C in 30 minutes, and remains at this level until the end.

Cubot KingKong Mini 4 Battery Settings

The Battery settings offer lots of options. You can monitor the battery status and usage by the app and/or the system.
