Smartphone battery life is oneof the main properties that affect consumer choice of model. A long battery life has become a proprietary feature of Apple smartphones, not least affecting the popularity of the iPhone.
Regular software updates shouldtheoretically reduce energy consumption. Whether this statement is true and applicable for models released several years ago, we decided to check iAppleBytes enthusiasts on the YouTube channel, who tested the autonomy of the six iPhone models on which the latest iOS 13.4.1 build was installed.
A competition in autonomy took place amongApple’s following models: iPhone SE, iPhone 6s, iPhone 7, iPhone 8, iPhone XR and iPhone 11. On smartphones with fully charged batteries, the Geekbench4 cross-platform benchmark was launched. The test lasted until all smartphones were completely turned off. According to the results of the competition, the effect of the update on the battery life was determined, and the most non-volatile models were identified.
As expected, the winner is the newestiPhone 11 model, which has a 3110 mAh battery and a processor with reduced power consumption. The smartphone worked for 6 hours 47 minutes. In second place was the iPhone XR model (2942 mAh), which entered the market in 2018, with a battery life of 5 hours 51 minutes. The remaining smartphones disconnected in the range from 3 hours 11 minutes to 3 hours 33 minutes.
When comparing battery lifesmartphones with a previous build of the operating system (iOS 13.4), it turned out that the “old” models (iPhone SE, 6s and 8) had practically no effect on the upgrade, and the iPhone XR smartphone even reduced battery life by 29 minutes.
For iPhone 7, run time until fully dischargedincreased by 11 minutes, but decreased compared with work under iOS 13.3.1. An update to the operating system for the new iPhone 11 showed a clear increase in battery life from update to update.
