Comparison between iPhone 4 and iPhone 5 on iOS 7

Apple released the latest iOS 7 System in WWDC 2013 this year, supported iOS 7 models include iPhone 4, iPhone 4 S, iPhone 5, iPod touch 16 GB/32 GB/64 GB, iPad 2, iPad 3, iPad 4, and iPad mini. However, not all supported models can use all functions of iOS 7. For example, iPhone 4 does not support Panoramic photography, camera filters, and AirDrop functions.

Some iOS developers have responded that the operation on iPhone 4 is obviously not smooth after the iOS 7 Beta version is installed, and it is very difficult to run, iOS 7 is not recommended for iPhone 4 and iPad of the first generation, which were launched two years ago using the A4 processor.

Foreign websites also perform performance tests on iPhone 5 and iPhone 4 installed with iOS 7. The average network speed of iPhone 4 is 22 Mbps, And the upload speed is 14 Mbps, the download speed of the iPhone 5 is 60 Mbps and the upload speed is 40 Mbps. In Geekbench's scoring test, iPhone 5 scored 1672, While iPhone 4 scored only 395.

So is iPhone 4 suitable for upgrading iOS 7? It may not be until the official version of iOS 7 is released this fall that Apple engineers have optimized the iOS 7 system to fit the iPhone 4 model.
