iOS 9’s Low Power Mode Enhances Battery Life by Processor Throttling, Benchmarks Reveal
Apple’s latest iOS 9 will preserve battery during ‘Low power mode’ mainly by employing an old-fashion method of processor throttling, reveal benchmark tests on beta versions of iOS 9.
‘Low Power Mode’ is definitely among the top improvements in the upcoming iOS, as Apple has claimed it can extend the battery life by three hours. But that coming on cost of processor’s performance may not be an entrancing facet for most of the users.
The benchmark test was performed on an iPhone 6 Plus running iOS 9; to record the performance scores, updated Geekbench 3 for iOS was used. According to the results, iPhone 6 Plus’ multi-core score dropped from 2,891 to 1,751, while single-core performance dropped from 1,606 to 1,019. The test results were substantiated after 40% decrease in performance was recorded on iPhone 5s as well.
Indeed, this is extraordinary compromise on processor’s performance. Apple will possibly reduce the margin to some extent with the final build of iOS 9, for the benchmark tests was performed on beta version of software.
Apple has promised to add extra hours to battery life of its iPhones and iPads running iOS 9. It will be made possible by using a combination of power saving tactics, “so you get more battery life for the things you do every day. Thanks to ambient light and proximity sensors, your iPhone knows if it’s facedown on the table and prevents the screen from turning on, even when you receive a notification,” Apple explained earlier.
