OnePlus Watch 4: Specs Leak Reveals Minor Updates & IP69 Durability

The incoming OnePlus Watch 4 is shaping up to be an iterative update, with leaks suggesting a focus on refinement rather than radical change. Reports indicate the smartwatch is nearing launch, having recently passed EMVCo certification, but early specifications point to familiar hardware and a modest feature set. The core question for potential buyers: is this a worthwhile upgrade, or simply a polishing of an already solid foundation?

EMVCo Certification Signals Imminent Launch

Tipster Sudhanshu Ambhore first reported the OnePlus Watch 4’s appearance in the EMVCo database on X (formerly Twitter) (@Sudhanshu1414). This certification is a crucial step for devices with NFC-based contactless payment capabilities, suggesting the watch is close to release. The listing includes two model numbers – XL905 and XL907 – potentially indicating different variants, perhaps differing sizes or regional configurations. EMVCo certification ensures compatibility and security for mobile payment systems, a key feature for modern smartwatches.

Snapdragon W5 Gen 1: A Familiar Core

Perhaps the most discussed aspect of the leaks is the continued use of the Qualcomm Snapdragon W5 Gen 1 chipset. First introduced in 2022, this processor powered the OnePlus Watch 3 and remains the expected heart of the Watch 4. Gizmochina highlights that Qualcomm released the newer W5 Gen 2 series in August 2025, making the choice to stick with the older chip somewhat surprising. While the W5 Gen 1 is a capable processor, it raises questions about performance gains compared to its predecessor. OnePlus may be prioritizing power efficiency and stability over raw speed, a pragmatic approach but one that might not excite users seeking a significant performance boost.

Display and Design: Evolutionary, Not Revolutionary

The display is also expected to remain largely unchanged. Leaks point to a 1.5-inch LTPO AMOLED panel with a 466 x 466 resolution, mirroring the specifications of the 47mm OnePlus Watch 3. Gadgets & Wearables notes this suggests a similar visual experience. The casing size is rumored to be 47mm, a slight increase, but the overall design language appears to be consistent with the previous generation. LTPO AMOLED technology allows for variable refresh rates, contributing to improved battery life by dynamically adjusting the display’s power consumption based on the content being shown.

Battery Capacity: Incremental Improvement

The reported battery capacity of 646mAh is only slightly larger than the 631mAh battery found in the OnePlus Watch 3. While a larger battery *could* translate to longer runtimes, the actual improvement will depend on software optimization and the efficiency of the Snapdragon W5 Gen 1. The Watch 3 already offered respectable battery life – four to six days on a single charge – so the increase may not be dramatically noticeable. Android Central suggests the gains might be marginal.

Durability: A Potential Standout Feature

One area where the OnePlus Watch 4 could spot a genuine upgrade is durability. Leaks suggest an IP69 rating, which would provide significantly enhanced protection against dust and water compared to the more common IP68 rating. IP69 signifies resistance to close-range, high-pressure, and high-temperature spray downs, making the watch more suitable for demanding environments and active lifestyles. What we have is a notable improvement, as durability is a key consideration for many smartwatch users.

Software: Wear OS 6 on the Horizon?

The software situation is somewhat unclear. Initial reports suggested Wear OS 5, but the EMVCo certification listing points towards Wear OS 6. Given the timing, Wear OS 6 seems more likely. Google’s Wear OS provides access to a wide range of apps and services, as well as regular software updates. The specific version of Wear OS will significantly impact the user experience and the long-term value of the device.

What Comes Next: Certification and Launch

With EMVCo certification now complete, the OnePlus Watch 4 is likely to move towards final testing and regulatory approvals. A launch is expected in the coming weeks or months. The key will be how OnePlus positions the Watch 4 in the market. If marketed as a premium upgrade, the lack of significant hardware changes could be a drawback. However, if positioned as a refined and more durable version of the Watch 3, it could appeal to users who prioritize reliability and a proven experience. Further details, including pricing and availability, will emerge as the launch date approaches. The focus now shifts to software optimization and ensuring a smooth user experience with the latest version of Wear OS.
