Earlier this week, Apple released their much anticipated operating system update in iOS 9. It is compatible with all devices that were already capable of running iOS 8, and promises to bring a much more refined and secure experience to the Apple mobile system. However, many people are complaining that it’s not doing what it’s supposed to do – namely, instead of making the phone snappier and easier to do things, it is running more slowly and showing lag in many places. If you are one of the people who are suffering from this, here are a couple of things that you can try to remedy this.

The first thing you can try is a hidden shortcut that flushes the memory of your device (if I understand correctly). It DOESN’T delete any files or make any visible changes to any of your stuff, so you can try this risk-free. Here’s how you do it. Open one of the default Apple apps (I usually use the Stocks or Weather app), then hold down the power button until you see the “slide to power off” prompt. At this point, release the power button, but now hold the home button. Continue doing this until the screen flashes black, and the phone exits the shutdown screen and returns to the home screen. I used this method when my iPhone 5S was experiencing a lot of lag after the update, and remarkably, this seemed to speed it right up again. Note, I am not sure if you NEED to be in an app to do this successfully. When I learned of this technique a few versions ago, I was told to be in the Weather, Stocks, or iTunes app. However, it does seem like you can do this from anywhere. Maybe it’s just easer to do it from within an app, because then you can see for sure than you return to the home screen.

The second method you can try is to reset your settings. This will erase things like wifi passwords, bluetooth profiles, notification settings, wallpaper, and privacy controls, but will not erase your apps, messages, or data. You do this from within the Settings app. then General, and then at the bottom, Reset. On the next screen, simply tap “Reset All Settings” to revert all of your settings back to defaults. Some people have noted that this method works, especially if your iPhone has evolved through multiple upgrade versions and has had time to accumulate a lot of “junk”. Resetting all settings is a quick and easy way to clear out the cruft without actually going through the hassle of doing a full erase.

In any case, if your iPhone is running slowly after updating to iOS 9, then hopefully one of these two quick tricks will work for you to get your device back up and running quickly again. The first method worked for me, and is risk-free, and the second method only requires some basic resetting of your customized settings, which may be a fair trade for a speedy, responsive iPhone again!
