Apple Watch Battery Test: From SE to Ultra, Guess Who Wins? [VIDEO]

A detailed battery comparison by HotshotTek puts Apple’s complete watch lineup to the test, evaluating models from the Apple Watch SE to the latest Ultra editions. The results may surprise anyone who assumes newer always means better.

The test was designed to replicate everyday use while keeping conditions as fair as possible across all devices. Each watch ran through the same tasks, including fitness tracking, notifications, display activity, and standby time.

Interestingly, some older or budget-friendly models outlasted their premium counterparts. For example, the Apple Watch SE, known for its stripped-down feature set, demonstrated impressive stamina compared to high-end models packed with sensors and brighter displays. This highlights a tradeoff that Apple users may not always consider: more features often come at the cost of reduced endurance.

The Ultra series, built with adventure and long-haul use in mind, did perform well in absolute terms. However, when efficiency and value were factored in, a few less-expected winners emerged.

For consumers, this comparison offers an important reminder: buying the flagship device doesn’t always guarantee the best results for your needs. If your top priority is battery life rather than the latest advanced features, you may be better served by one of Apple’s more affordable models.

The test also shows how Apple’s design philosophy hasn’t strayed far over the years. While the brand continues to innovate with health and fitness tools, its approach to battery has remained consistent, relying on efficient hardware and software optimizations rather than dramatically increasing battery size.
