Overview

Released in late 2015, the OnePlus X represented a distinct design detour for OnePlus, steering away from its larger flagship lineage toward a compact, design-centric footprint. Built around a 5.0-inch AMOLED panel featuring full HD resolution with a 71.3% screen-to-body ratio, the handset offered rich contrast and deep blacks unusual for mid-range phones of its time. Under the hood, it relied on the proven Qualcomm Snapdragon 801 chipset built on a 28 nm process, coupled with 3GB of RAM and 16GB of expandable internal storage. Its physical build featured a textured aluminum frame, dual glass panels, a 13 MP rear camera with phase detection autofocus, and the signature physical Alert Slider for quick notification profiles.

Because of its small form factor and striking glass-and-metal aesthetic, the OnePlus X occupies a unique space in smartphone history. It appeals to legacy hardware enthusiasts, collectors, and minimalists looking for a pocketable 5-inch device. Originally shipping with OxygenOS built on Android 5.1.1 Lollipop and officially updated to Android 6.0.1 Marshmallow, the device requires mindful software and battery management to remain useful today. Users frequently keep these devices running as dedicated media players, offline utilities, or functional exhibits of mid-2010s mobile design.

Design and build

The OnePlus X is a well-crafted device that stands out for its premium materials and compact dimensions. Weighing in at just 138 grams, it feels light in the hand while still conveying a sense of sturdiness thanks to its aluminum frame and Gorilla Glass 3 front and back. The design features a textured back that not only enhances grip but also adds an aesthetic touch. However, the all-glass design, while beautiful, makes it susceptible to cracks and scratches, especially for users who may not use a case.

Everyday performance

In terms of everyday performance, the OnePlus X is a mixed bag in 2026. While the Snapdragon 801 chipset and 3GB of RAM were impressive at launch, they now struggle with modern apps and multitasking demands. Basic tasks like social media browsing and messaging are manageable, but users may experience lag with heavier applications or multitasking. The 16GB of internal storage, while expandable, may feel limiting, especially as app sizes have increased over the years. For those who primarily use their phone for calls, texts, and light browsing, the OnePlus X can still serve its purpose.

Battery, durability, and longevity

One of the most significant drawbacks of the OnePlus X is its battery life. The 2525 mAh non-removable Li-Po battery degrades over time, leading to shorter runtimes and unexpected shutdowns. Users often report that they need to charge the device multiple times a day, particularly as the battery ages. Additionally, the battery's inability to be replaced without professional help can be a major inconvenience. The device's AMOLED display is also prone to burn-in, and the glass construction makes it vulnerable to impact damage, which can be a concern for users who are not careful.

Common issues owners hit

As with any aging device, the OnePlus X has its share of common issues that owners encounter. The most notable problems include:

• Battery degradation leading to poor performance and unexpected shutdowns.
• Screen burn-in from prolonged use, particularly for static images.
• Cracked glass from drops or impacts, which can be costly to repair.
• Limited software updates and compatibility issues with newer apps.

Who it's for

The OnePlus X is best suited for users who appreciate a compact design and are nostalgic for mid-2010s technology. It appeals to collectors and legacy hardware enthusiasts who value aesthetics over cutting-edge performance. Additionally, it can serve as a secondary device for media consumption or as a dedicated utility tool for specific tasks. However, for anyone seeking a reliable daily driver in 2026, the OnePlus X may not meet modern expectations.

Bottom line

The OnePlus X is a charming device for those who appreciate compact design and nostalgia, but its aging components and software limitations may hinder its practicality for daily use in 2026. While it remains a beautiful piece of technology, potential owners should weigh its shortcomings against their needs and consider whether a more modern alternative would better suit their lifestyle.
