Yes, Low Power Mode can impact the speed of large downloads on 5G, but the effect varies depending on the iPhone model[3][5].
Here's how Low Power Mode affects 5G and download speeds:
* iPhone 12 and 13 series: Low Power Mode disables 5G except when streaming videos or performing large downloads[2][5]. In some cases, it may also disable 5G standalone mode[2]. When 5G is disabled, the phone will switch to 4G or LTE networks, which are slower[3].
* iPhone 14 series and newer: Low Power Mode does not turn off 5G due to the improved efficiency of Apple's 5G modems and the newer devices' power management system[3].
5G is capable of peak data rates up to 20 gigabits per second (Gbps), and average 5G download speeds have been recorded at 186.3 Mbit/s in the U.S[4][6]. The most widely used form of 5G, sub-6 GHz 5G (mid-band), can deliver data rates ranging from 10 to 1,000 megabits per second (Mbps)[4]. Low-band frequencies offer data rates in the range of 5â250 megabits per second (Mbps)[4]. When Low Power Mode is active on iPhone 12 and 13 series, the speeds will be limited to those of 4G or LTE networks unless performing specific tasks like video streaming or large downloads[3][5].
