The recently unveiled iPhone 12 series is the first for Apple smartphones to receive support for fifth-generation 5G networks. At the same time, the battery capacity of smartphones has been reduced. Tom's Guide tested the new iPhone 12 Pro and iPhone 12 to determine how these changes affected battery life. We also compared the autonomy of the iPhone with competing flagships from leading manufacturers running Android.
To check the autonomy of the devices, a standard technique was used, when the battery was fully charged, the brightness of smartphones was set to 150 nits and the browser was connected, which refreshes the page at intervals of 30 minutes. As a result, experts were convinced that the battery life of the iPhone 12 decreased compared to the iPhone 11 model from 11 hours 16 minutes, to 10 hours 23 minutes, even when working in 4G mode. In 5G mode, the iPhone 12 lasted 8 hours and 25 minutes. For the iPhone 12 Pro model in 5G mode, this time was 9 hours 6 minutes, which is explained by a more capacious battery.
When testing Android devices, it turned out that the Samsung Galaxy S20 5G at a refresh rate of 60 Hz lasted 9 hours and 31 minutes, and at 120 Hz mode - 8 hours and 4 minutes. The Samsung Galaxy S20 Plus 5G lasted 10 hours 31 minutes and 8 hours 55 minutes, respectively.
The OnePlus 8T smartphone in the fifth generation networks lasted 9 hours 58 minutes at 60 Hz screen refresh mode - 10 hours 49 minutes and at 120 Hz mode - 9 hours 58 minutes. The Google Pixel smartphone lasted 9 hours 29 minutes in 90 Hz refresh mode.
Apple developers have stated that iOS includes smart switching between 5G and LTE networks to reduce power consumption. For example, iPhone 12 switches to 4G mode when listening to audio while the screen is locked. However, experts point out that the maximum battery saving in the iPhone can be achieved by manually switching to "LTE only" mode, that is, actually turning off the ability to work with fifth generation networks.
