iPhone 12 4G VS 5G power consumption test battery life difference up to 20%

iPhone 12 supports 5G across the board, but the power consumption must not be ignored. What is the difference between the power consumption of the new iPhone when using 5G and when using 4G?

A test from Tom's Guide found that the iPhone 12 and iPhone 12 Pro consume more power when using 5G than 4G. They set up a test that loads a new web page every 30 seconds until the battery runs out.

Distance: 1 hour and 58 minutes (down 19%)


iPhone 12 Pro@4G: 11 hours and 24 minutes
iPhone 12 Pro@5G: 9 hours and 6 minutes
Distance: 2 hours and 18 minutes (down 20%)


Samsung Galaxy S20 Plus@5G: 10 hours and 31 minutes
Google Pixel 5@5G: 9 hours and 29 minutes
Perhaps because Apple also understands the power consumption of 5G, it has designed the Smart Data Mode, which will intelligently switch between 4G/5G according to the user's usage, and use 4G when the data speed is not too high, but use 5G when the speed is required.
