A notable number of users who have installed iOS 9 on their iPhones, iPad, and iPod touch have discovered that iOS 9 has caused performance to suffer, with annoying lag, choppiness in interactions, delayed response from the user interface, and just general performance degradation. That lag can be notable enough to make the device feel considerably slower on iOS 9 than when compared to the same hardware running a prior version of iOS. This can be a frustrating experience, but there are a couple of tweaks you can make to immediately improve the performance of a sluggish iOS 9 device, effectively speeding up the iPhone, iPad, or iPod touch again.
NOTE: This does NOT completely fix the freezing issue which may be associated with Game Center. This freezing issue might be fixed in iOS 9.1, which is my hope. The following is what I did to improve performance for Clash of Clans, which should also work for Hay Day as well.
Disable Transparency & Motion
Some devices seem to struggle to render visual effects on iOS 9, by disabling transparency and motion eye candy, you can speed up the general interactivity of iOS on an older device.
- Go to Settings > General.
- Choose Accessibility.
- Locate Increase Contrast and choose Reduce Transparency, toggling it to ON.
- Go back to Accessibility and locate Reduce Motion, toggle that to ON as well.
The end result is that iOS will look less fancy without any translucent windows or crazy zooming in and out motion effects, but the tradeoff for a slightly uglier iOS experience is notably better performance on virtually every model. Also, by enabling Reduce Motion, you end up with a nice transition effect, which some users prefer anyway.
Disable Background App Refresh
Background App Refresh is an interesting feature that allows background app activity in iOS, but while its well intentioned it can lead to a decrease in device performance. Turning it off is easy, and the only side effect is that when you open an app that gets details from the internet, it refreshes on open rather than in the background no big deal.
- Go to Settings > General.
- Find Background App Refresh and toggle it to OFF.
By completing these steps, not only do I notice a big reduction in choppiness and overall performance issues in the games, but even web browsing, like using these forums is a much better experience. Everything responds faster, and I no longer experience the keyboard lag I used to struggle with sometimes.
If this does not fix any issues for you, or you do not like the change in appearance of iOS, simply backtrack the steps shown above to revert the changes.
