Low Data Mode is a feature available on iPhones and iPads with iOS 13 and later that restricts background network use and saves cellular and Wi-Fi usage. This feature is useful if your cellular or internet plan limits your data usage, or if youre in an area with slow data speeds. When Low Data Mode is turned on, automatic downloads and background app refreshes are turned off, and videos and music will stream in lower quality. The quality of streaming content might be reduced, and internet pages may take more time to load. Built-in iOS apps and services adapt to Low Data Mode by turning off automatic updates, reducing video quality, and pausing updates to services such as iCloud Photos. Low Data Mode can be turned on separately for cellular and Wi-Fi, and the settings might vary depending on your carrier.
