Manage Smart Data Mode

5G is amazing. But it can also ding your iPhone’s battery life. To make that less of an issue, your iPhone 13 or iPhone 13 Pro features Smart Data Mode, a functionality that switches between 5G and 4G depending on network activity. For example, you won’t need 5G while scrolling down your Twitter and Facebook timelines. Smart Data Mode will make your iPhone use 4G in those instances. But if you choose to download a video on Apple TV, your iPhone 13 Pro automatically takes advantage of faster 5G. You can manage Smart Data Mode via Settings > Cellular > Voice & Data. Select 5G Auto to enable Smart Data Mode or 5G On to disable the functionality — the latter setting will force your iPhone to use 5G all the time but may end up draining your battery.
