Because you don’t always need the speed.
Apple’s iPhone 12 officially adds support for 5G and while you can finally take advantage of superfast download speeds, it also has a catch. 5G often uses more bandwidth and also consumes more data so if you’re on a limited data plan, you may have to keep checking your data allotment before you get charged extra. Additionally, 5G antennas tend to consume more power, which is actually one of the main causes of battery drain on the iPhone 12.
Thankfully, Apple has included settings on iOS that can let you control how 5G and data are used. Just follow these steps:
Head on to Settings and go to the Cellular menu.
Inside the Cellular menu, look for Cellular Data Options.
Look for two settings: Voice & Data and Data Mode.
Under Voice & Data, you can choose how 5G is used. 5G Auto automatically switches between 4G and 5G depending on the signal available.
Under Data Mode, you have the choice to consume less or more data under 5G, or in standard mode.
Playing with these settings should help you decide how you want your 5G-enabled iPhone to work, which in turn could help save your data and battery.
