Apple gadgets are known for their “longevity” – even the devices that rolled off the assembly line in 2015 received the latest firmware version at the end of last year. To check whether the software update affected one of the key functions of the “oldies”, iAppleBytes YouTube channel bloggers tested the autonomy of six iPhone models running iOS 13.4.1, the latest revision of the proprietary mobile OS.
The experiment involved iPhone SE, iPhone 6s, iPhone 7, iPhone 8, iPhone XR and iPhone 11. Before the test, all the devices were fully charged, after which the popular Geekbench 4 application was launched on them. When the last of the “experimental” ones turned off, enthusiasts summed up the results of an impromptu competition, and at the same time compared the results of all devices with previously obtained values for previous versions of the OS.
The newest model lasted the longest – due to a 3110 mAh battery and an energy-efficient processor, the smartphone withstood 6 hours and 47 minutes of testing. The second place went to last year’s XR (2942 mAh), which disconnected a little earlier – after 5 hours and 51 minutes. The results of the other devices were almost identical – they all finished with a minimum margin from each other, get off the distance between the marks 3:11 and 3:33.
