The 240Hz refresh rate of the Sharp AQUOS R9 Pro can significantly impact battery life. Higher refresh rates require more power, leading to a direct negative effect on battery performance. For instance, tests on smartphones with varying refresh rates have shown that switching from 60Hz to 120Hz can increase power consumption by approximately 10% to 30%, depending on the activity being performed[2][5][8].
In practical terms, users of devices with high refresh rates often report a loss of around 1 hour of battery life when operating at 240Hz compared to lower rates[3]. This is primarily because the GPU must work harder to render frames at a faster rate, which increases overall power draw[5].
However, many modern smartphones, including the AQUOS R9 Pro, may feature adaptive refresh rate technology. This allows the device to adjust the refresh rate dynamically based on user activity, potentially mitigating some of the battery drain associated with high refresh rates during less demanding tasks[2][5].
Overall, while the AQUOS R9 Pro's 240Hz display offers enhanced visual performance and responsiveness, it does come with trade-offs in battery longevity that users should consider based on their usage patterns.
