With dimensions of 136.5 x 66.7 x 11.2 mm and weighing just 135 grams, it offers a sleek and lightweight experience. The device features a Hybrid Dual SIM system, supporting both Micro-SIM and Nano-SIM options, making it versatile for different users. Available in a variety of colors such as Glacier Grey/Silver, Blue/Sheer Gold, Charcoal Black, Pearl White, Glamor Red, and Lemon Yellow, it provides an aesthetic choice for everyone. Unfortunately, this model has been discontinued, but it offers a snapshot of the smartphone innovation of its time.
Display
The Asus Zenfone Go ZB450KL is equipped with a 4.5-inch IPS LCD display, offering a moderate screen-to-body ratio of approximately 61.3%. With a resolution of 480 x 854 pixels and a pixel density of around 218 ppi, it ensures acceptable clarity for everyday use. Although not the sharpest display on the market, its compact size might appeal to users looking for a functional, pocket-friendly device.
Performance
Under the hood, the Zenfone Go ZB450KL is powered by the Qualcomm MSM8916 Snapdragon 410 chipset (28 nm), a quad-core 1.2 GHz Cortex-A53 CPU, and an Adreno 306 GPU. Although not designed for heavy gaming or intensive multitasking, this setup ensures a smooth performance for basic tasks. Running on Android 6 (Marshmallow) with ZenUI 2, it provides a user-friendly interface that was quite popular at the time.
Memory and Storage
The device comes with 1GB of RAM and 8GB of internal storage, which may seem limited by today's standards. However, the inclusion of a microSDXC card slot allows users to expand storage, albeit at the cost of using the shared SIM slot. This flexibility in storage can be particularly useful for users who need more space for apps, photos, and other media.

Meanwhile, the selfie camera is a 2 MP sensor with an f/2.4 aperture. These specifications suggest a basic photography experience, suitable for casual shots and video calls.
Battery Life
The device is powered by a removable Li-Po 2070 mAh battery. While this isn't the largest capacity available, given the device's hardware specifications and display size, it should offer a day of average use. Being removable, the battery provides the convenience of swapping it out with a spare, extending the device’s usability throughout the day.
Connectivity and Extras
On the connectivity front, the Zenfone Go ZB450KL supports Wi-Fi 802.11 b/g/n, Wi-Fi Direct, Bluetooth 4.0 with A2DP and EDR, and has GPS, GLONASS, and BDS for positioning. Unfortunately, NFC is absent, which might be a drawback for those relying on mobile payments. The device includes an FM radio and a microUSB 2.0 port for charging and data transfer.
For those who still appreciate wired audio, it offers a 3.5mm headphone jack. The device also supports essential sensors such as an Accelerometer, proximity sensor, and compass, enhancing its functional appeal.
Network and Communication
The Asus Zenfone Go ZB450KL supports GSM, HSPA, and LTE technologies, ensuring versatile network compatibility. It covers a range of 2G, 3G, and 4G LTE bands making it adaptable to various regions. With HSPA 21.1/5.76 Mbps and LTE Cat4 150/50 Mbps speeds, users can expect decent connectivity performance.
Overall Assessment
