Low Power Mode handles 5G standalone and non-standalone networks differently for video streaming, depending on the iPhone model. On iPhone 12 and 13 models, Low Power Mode disables 5G except in some cases such as video streaming and large downloads[3]. However, for iPhone 12 models specifically, Low Power Mode disables 5G standalone network access entirely, even for video streaming and large downloads, causing them to fall back on non-standalone 5G networks[1]. The iPhone 14 series and newer models do not turn off 5G due to improved power management[1].
5G Standalone (SA) utilizes a new core architecture and cloud-based platform, offering lower latency, higher data rates, and improved energy efficiency[2]. It allows 5G to reach its full potential with high speeds and bandwidth, saving costs for carriers and enhancing user performance[2]. In contrast, 5G Non-Standalone (NSA) relies on the existing 4G LTE network core, providing improved performance over 4G but not fully exploiting 5G capabilities[2]. While 5G NSA can enable enhanced mobile broadband applications like video streaming, it cannot deliver the same level of low latency or reliability as 5G SA[2].
