A compact version of the OnePlus Watch 3 might be on the way, but it faces a significant hurdle ahead.

      The OnePlus Watch 3 stands out as a commendable Wear OS smartwatch, boasting a claimed five-day battery life that significantly surpasses rivals like the Galaxy Watch 7 and Watch Ultra. However, it's not without its flaws, and there are several areas where OnePlus could enhance the device, which they are reportedly addressing in a new model expected later this year.

      A representative from OnePlus recently confirmed that they are developing a new version of the OnePlus Watch — possibly a variant of the Watch 3. While it may not be released immediately, the company is said to be resolving two issues that some users have raised regarding the current model. This newer iteration might feature a smaller and lighter design, which could introduce new challenges as discussed below.

      A smaller OnePlus Watch 3 would be advantageous

      The OnePlus Watch 3 has a distinctly premium design. When the Watch 2 was launched last year, I recognized it as one of the most aesthetically pleasing Wear OS smartwatches. The Watch 3 has further elevated this with its premium look, incorporating a functional rotating crown button and a titanium bezel encircling the circular display.

      However, the stainless steel body adds considerable weight, which may make the Watch 3 uncomfortable for many users. Weighing almost 50 grams (0.035 ounces) without straps, the OnePlus Watch 3 is undeniably one of the heftiest smartwatches available. The large 47mm circular dial does not enhance its ergonomics.

      To address this issue, OnePlus is working on a smaller variant. Dr. Leo Zhang, head of R&D at OnePlus’ Health Lab, confirmed this in an interview with Pulse by Wearable (via 9to5Google). He indicated that feedback from customers regarding the current weight of the OnePlus Watch 3 — and even the Watch 2, particularly among those with smaller wrists which tends to be "typically women" — has prompted the development of a smaller watch.

      Zhang noted that this issue will be addressed "this year," implying that a new OnePlus Watch may launch in 2025. It's possible that while groundwork for this watch is laid this year, it may not debut until the next refresh cycle in early 2026.

      Zhang did not specify the exact size OnePlus is considering for the smaller variant or clarify if it will be simply a smaller version of the OnePlus Watch 3 or a completely new device. Interestingly, last year, OnePlus introduced the Watch 2R, which was around 20 grams lighter but featured lower quality materials. Hopefully, this won't be the case with the new device.

      A smaller watch is a proven strategy

      This approach has already been adopted by major players in the smartwatch market. Apple offers the Watch Series 10 in two sizes — 42mm and 44mm. Similarly, Samsung provides options of 44mm and 40mm. Regardless of the size differences, both variants maintain the same design and button layout, with the primary distinction being the screen size.

      Anticipating that OnePlus will simply reduce the size of the Watch 3 while keeping most design elements intact isn't unreasonable. This dual-size strategy should help OnePlus attract a broader user base. Additionally, it could enable the brand to lower manufacturing costs, ideally leading to more competitive pricing.

      An unavoidable challenge

      While a smaller design could enhance wearability, it will also present a significant challenge. The reduced size of the OnePlus Watch 3 would necessitate a smaller battery, which is its standout feature.

      The 650mAh battery in the OnePlus Watch 3 is one of the largest in smartwatches, allowing the brand to claim an impressive five-day battery life. In contrast, competitors like the Apple Watch Ultra 2 and Galaxy Watch Ultra, equipped with slightly smaller batteries (around 550mAh), only last up to two days under regular use.

      If OnePlus downsizes the Watch 3, a smaller battery will be essential. Consequently, this would likely result in compromises regarding battery life. It’s hard to foresee how much of a reduction we might see and how it would affect OnePlus' five-day battery claims, but a decline seems likely.

      There is potential for advanced battery technology to assist OnePlus, but the likelihood of this being ready by 2025 appears low.

      Enhanced connectivity on the horizon

      Alongside the need for a smaller design, Zhang also recognized the absence of global LTE support. He stated that integrating LTE technology, which would facilitate calling and messaging without a phone, especially during outdoor activities, is relatively simple. The real challenge, according to Zhang, lies in securing support from carriers.

      OnePlus is currently collaborating with carriers, especially in Europe, to develop dedicated data plans for the smartwatch. If successful, we might see an LTE option with the newer version of the OnePlus Watch 3, although it's unclear if the current model will have the same.

      The challenge ahead
