Google’s upcoming Pixel Watch 4 is set to debut a significant design change with the introduction of a side-mounted charging system. This departure from the traditional back-mounted charging method aims to enhance user convenience, improve repairability, and potentially offer faster charging speeds.
Design and Charging Mechanism
Leaked renders reveal that the Pixel Watch 4 will feature charging contacts on the left side of the device, opposite the digital crown. This design includes an indentation housing two charging pins, allowing the watch to rest on its side during charging. This orientation not only keeps the display visible—transforming the watch into a mini-desk clock—but also facilitates easier interaction with the device while it charges.

The accompanying charging cradle is designed to support the watch’s circular body, ensuring a secure fit. This side-mounted approach is expected to offer a 25% increase in charging speed compared to previous models, addressing user concerns about slow charging times.

Enhanced Repairability
By relocating the charging contacts to the side, Google has freed up space on the back panel for additional health sensors and improved the device’s repairability. The absence of rear charging pins simplifies the process of accessing internal components, making repairs more straightforward. This modular design marks a significant shift from previous Pixel Watch models, which were often criticized for their lack of repairability.

Design Consistency and Variants
Despite the charging system overhaul, the Pixel Watch 4 maintains the aesthetic of its predecessors, featuring a circular face and right-side crown. The device is expected to be available in two sizes—41mm and 45mm—and offered in four case colors: Black, Silver, Gold, and Moonstone. These options align with previous models, providing users with familiar choices.

Battery and Performance Enhancements
The Pixel Watch 4 is rumored to include an 8% increase in battery capacity, potentially offering up to 30 hours of use for the 41mm model and 40 hours for the 45mm variant, even with the always-on display activated. This improvement addresses previous concerns about battery life and positions the Pixel Watch 4 as a more reliable companion for daily use.

Pricing and Availability
Pricing for the Pixel Watch 4 is expected to remain consistent with its predecessor, with Wi-Fi versions starting at $349 and LTE models reaching up to $449. The official unveiling is anticipated at Google’s event on August 20, 2025, alongside the Pixel 10 smartphone series.

Considerations and Potential Drawbacks
While the side-mounted charging system offers several advantages, some concerns have been raised regarding the exposed charging pins on the watch’s side. These pins may affect the device’s aesthetics and could be susceptible to damage or wear over time. Users will need to consider these factors when evaluating the overall design and functionality of the Pixel Watch 4.
