iOS 12 performance promising, tested with iPhone 5s

Apple have received some criticism due to slowdowns on older iPhones. When the battery can’t keep the charge anymore, the CPU is clocked down to prevent unexpected shutdowns. Pair this with new iOS releases that allegedly slows down older devices.

A slower CPU clock reduce the performance of the device and it may seem more sluggish and slow to use. This is why apple released the iPhone battery replacement program where you get the battery replaced for $29 for eligible devices through December 31, 2018.

With all of the above said, early testing reports of iOS 12 claims it performs very well on older devices. The interface feels more fluid, and most of the lag you could feel in older iOS versions are gone. This is great news for people that use devices a few years old.

If money is tight, a cheap battery replacement combined with iOS 12 should breathe some new life into your device. This is really good news economical wise and I am sure Apple will get some positive PR score on this.

iPhone 5s iOS 12 Beta Speed Test

I decided to do some un-scientific test between the current latest iOS 11, and the upcoming 12 to see how much faster it feels on the oldest supported device. My trusty iPhone 5s was fished up from the drawer, charged to 100% and got to do some work again.

A quick note: Remember that beta software could have certain features deactivated. This could affect the results shown below in a negative way. When the final iOS 12 gets released, speeds could be even faster. Ill update this article when the final release is available.

Results

We can clearly see that iOS 12 scores better.

The interface overall feels more responsive compared to iOS 11. The keyboard pops up faster, the camera starts faster, apps load a little faster and most things generally feels snappy. The iPhone 5s felt usable again and not that laggy compared to before. The benchmarks above also show that it is faster. Are you excited for iOS 12?
