Yes, Low Power Mode can impact the user experience of video streaming on 5G-capable iPhones[1][2][7]. When Low Power Mode is activated, 5G is disabled on iPhone 12 and 13 models, except when streaming videos or downloading large files, as these activities require faster internet speeds[1][4][7]. For iPhone 14 models and later, 5G is not disabled due to the improved efficiency of newer Apple 5G modems and power management[5].
Here's how Low Power Mode affects video streaming and overall user experience:
* 5G Connectivity: Low Power Mode on iPhone 12 and 13 models typically disables 5G, but makes an exception for video streaming and large downloads, allowing these activities to use 5G[1][4][7].
* 5G Standalone: Low Power Mode disables 5G Standalone on iPhone 12 models[5][7]. This means video streaming and large downloads will fall back on non-standalone 5G networks[5].
* Performance: Low Power Mode reduces the CPU and GPU performance, which may result in slower app opening times and a slight impact on graphics-intensive games[1][5].
* Refresh Rate: On iPhone models with ProMotion displays, Low Power Mode limits the display refresh rate to 60Hz, which can make motion appear less smooth[5][7].
* Video Quality and Energy Consumption: Higher video quality settings consume more energy and network traffic[2]. Users can reduce battery consumption by choosing lower video quality settings, though this may negatively affect the viewing experience[2].
* Other factors: Low Power Mode also reduces background app refresh, automatic downloads, and some visual effects, which can indirectly impact the video streaming experience[1][7].
