iOS 10.3 Beta 1 Vs iOS 10.2.1 Speed Comparison Shows Performance Improvements Thanks To APFS

iOS 10.3 beta 1 Vs iOS 10.2.1 side-by-side speed test comparison videos show APFS has indeed brought performance improvements to various iPhone models running the latest firmware. Here are the details.

A couple of days ago, Apple released the first beta of iOS 10.3 to developers, and yesterday it made its way to the public beta program as well. That means that developers and enthusiasts the world over are now starting to get to grips with what Apple’s latest beta has to offer.


As far as betas go, it has quite a bit to offer on paper, but how does that translate into performance on iPhones? We’re glad you asked, because iAppleBytes has done what it does best. It has taken a set of iPhone 6s, 6, 5s, and 5 and installed the iOS 10.3 beta 1 on each of the devices. These have been put against another set of similar devices running iOS 10.2.1 final.

Doing so, the YouTuber has been able to draw some conclusions over whether the new software is any faster, or indeed any slower than the software it replaces. This batch of tests is particularly interesting because the first beta of iOS 10.3 is the first iOS outing of Apple’s new file system, APFS. Would APFS make for a speed bump, perhaps?

As it turns out, it does. And quite a dramatic one at that.

All iPhones running iOS 10.3 beta 1 start up considerably faster than when they were running iOS 10.2.1. To put that into numbers, you can expect faster start up times by around 3 seconds faster on the 6s running iOS 10.3 beta 1 and up to around 7 seconds on the iPhone 5. In between, the iPhone 6 and iPhone 5s display similar improvements.

Geekbench also scores better on iOS 10.3 beta 1, both in single-core and multi-core scores. There is an odd one out however, with the iPhone 5 bucking the trend, perhaps because it’s a 32-bit device? It’s early days for iOS 10.3, but the initial indications are good for those who own older iPhones and are also fans of outright speed. If APFS is indeed faster than the existing solution, then that bodes well moving forward.
