While iOS 7 on this smartphone runs smoothly and quickly, all this is essentially reflected on the battery charge.
As a result of tests carried out by the website Ars Technica, battery performance has been compared on the basis of the iPhone 5 iOS iOS 6 and 7 in the process of web browsing on Wi-Fi. Experts report that the phone was used by plants dumped without any software modifications.
It was later revealed that the installed iOS 6 smartphone enough charge on the pages in just over 11 hours. As for browsing on the iPhone 5 with iOS installed 7, it has been demonstrated here is much more modest figure – 7.4 hours.
