The iPhone 12 lineup is the first from Apple to support the much-hyped and speedier 5G connectivity. While the Cupertino giant talked about the phone’s 5G capabilities at great length during the event, Apple did not reveal the 5G modem present onboard. An iPhone 12 teardown video has, however, now shed light on this piece of information.

The 5nm Snapdragon X60 modem would have been more power-efficient than the 7nm X55 modem that’s currently baked into the iPhone 12 series. This, along with the smaller size of the batteries as compared to the iPhone 11 series, could together be the reason for the 20% impact in battery life that has been seen in real-life testing.
