The iPhone 5s, being an “s” upgrade, brings a lot of under-the-hood changes that make the whole experience of using the device much faster and more responsive.
In this post, we look at the performance improvements in the iPhone 5s thanks to its new A7 chip with a 2x faster 64-bit CPU and a 2x faster GPU by comparing it to the older iPhone 5, and you could say the iPhone 5c as well, since it comes with the same components as the iPhone 5.
We compare the performance across three main areas: boot up time, app launch speed and web browsing performance. Keep in mind that these are real-world tests, and not benchmarks, so the difference in performance here would directly affect your daily-use experience.
Boot up was noticeably faster on the iPhone 5s than the iPhone 5, with the difference being about 4 seconds. While most of us don’t reboot our phones as often as we reboot our PCs/Macs, it’s always good to have a phone in a usable state as quickly as possible after powering it on.
App launches are usually quite time-consuming since they load content from the disk to the RAM (a time-consuming process) or they wait from a response from the network or wait for some other pre-startup tasks to complete. Stock app loaded a little faster on the iPhone 5s than the iPhone 5, but the difference was much more noticeable when opening games like Infinity Blade III, Plants vs. Zombies 2 and Asphalt 8.
The iPhone 5s, to our surprise, isn’t much faster at web browsing than the iPhone 5 on Wi-Fi. We visited iphonehacks.com, espn.com and apple.com, and didn’t see any noticeable difference in load times between the two.
Here’s a side-by-side video comparison of the iPhone 5s and iPhone 5, performing the activities mentioned above:
So while the early iPhone 5s benchmarks have shown that it is significantly faster than the iPhone 5 and rival smartphones, the iPhone 5s is only slightly faster than the iPhone 5 in our real world tests. You should, however, see noticeable improvements in gameplay when game developers add support for OpenGL ES 3.0.
