Dell has unexpectedly taken the lead in laptop battery life. The new version of the XPS 16, powered by Intel Panther Lake chips, outperformed even the MacBook Pro in tests. The secret lies not in a high-capacity battery, but in screen manufacturing technology previously unused in laptops. The model's main feature is a display with a variable refresh rate ranging from 1 to 120 Hz. Unlike standard panels, it can reduce the refresh rate to minimum values when displaying a static image, thereby conserving battery life. This technology has long been used in smartphones, but this is the first time it has been implemented in a laptop. In Notebookcheck's test, the model delivered up to 27 hours of web browsing on a battery rated at just 70 Wh. This is one of the best results in the history of testing since 2014. In doing so, the laptop outperformed most competitors, including Apple devices, which have traditionally been considered the gold standard for battery life. Interestingly, even previous record-holders either used higher-capacity batteries or ran on ARM chips with a focus on energy efficiency. For example, models with Qualcomm processors or batteries exceeding 80–140 Wh still failed to achieve such a balance between runtime and capacity. The key factors were the new panel from LG Display and optimization by Intel. In idle mode, the laptop consumes just 1.5–4.6 W—significantly less than previous generations. |
