A few months ago Apple unveiled iOS 9 for iPhone, iPod Touch and iPad and with it there came quite a number of amazing features.

However, as it is always said, every good thing comes with a bad side of it and so do the new update for the iOS devices. Many users have been complaining about this update ever since it showed up and even though the company has worked hard to fix a wide range of these problems in subsequent versions of iOS 9.1 and iOS 9.2, there are still some persistent problems. While some of these problems are kind of minor, there are others that are quite big; for instance, issues related to the Touch ID.

In this article, we have narrowed down some of the biggest iOS 9 problems that you may encounter when you update to the latest version of this Apple mobile OS.

Installation problems

iOS 9 was released in September and it was made available for quite a wide range of iPhones ranging from the iPhone 4S all the way to the latest iPhone 6S Plus. However, some users have complained that installing this new version of the OS is a huge problem. This only occurred during the first days as Apple servers were overwhelmed by the number of requests that were coming in.

Nonetheless, there are still quite a number of installation issues, among them frozen downloads as well as something to do with the inability to swipe to update right after the iOS 9 update has been installed. In case of frozen downloads, try holding down the power button plus the home button for about 10 seconds. Ideally, this is to jumpstart the process.

As far as the swiping to update issue is concerned, just unplug your iPhone from PC and iTunes. Even though this is not a guaranteed fix, but it should work for now, just like it did for us.

Touchscreen problems

In case the screen of your iPhone 5S stops responding right after updating to iOS 9, don’t fret. This is something that other iOS users have reported too and the good news is that there is a fix to that. Just hold down the power plus home buttons simultaneously and give the phone some time to reboot. After this, you can start using your screen as usual.

In case this doesn’t solve the problem for the first time, try it again and again until it works. Well, it may take up to three resets for it to work, so, don’t give up on the second try.

TouchID problems

The issue on TouchID is still affecting those using the iOS 9.1, with those affected claiming that the new version has brought in accuracy issues, while others are complaining about the fact that their fingerprints aren’t working when opening their devices.

In case you encounter a failing TouchID, try to re-train your fingerprints; but this time, make sure no sweat or dirt is on the sensor and your hands are clean and dry. You can then select “Settings>TouchID & Passcode>Enter your passcode” and on the next window, swipe from right on each fingerprint to delete. Follow this by tapping on “Add a fingerprint” to re-train the TouchID.

If this doesn’t work, you may want to reset your phone by holding down the power plus home button for 10 seconds.

Battery life problems

iOS 9 came in with promises of improved battery life. Well, this has been the case for some users who are reportedly getting up to an extra hour of juice after updating to the new OS. However, the story is not the same for all the iOS 9 users as some are talking of a contrasting battery life after updating to the latest version.

In case you notice this, don’t be in a rush to try some weird things! First of all check out your apps or rather battery usage in order to find out which apps are consuming a lot of power on your phone. This is available through “Settings>Battery” and you can check through the Battery Usage tool for more info. If you notice any odd happening, first try updating the app and if it doesn’t work, reinstall it or simply uninstall it to check whether there will be significant improvements with the battery life.

You can also switch to low power mode in order to save more juice. This tool is available via “Settings>Battery>Low Power Mode>On”. However, the phone will limit quite a number of processes, but you will be sure of several extra hours of battery life.

Playing around with display settings can also do the trick as it has on more than one occasion said that screens are the largest consumers of battery power. You can shut down auto brightness by going to “Settings>Display & Brightness>Auto-brightness>Off” and that’s it.

Wi-Fi problems

Wi-Fi problems are a “norm” with all the iOS versions and to find them on iOS 9 shouldn’t surprise many. However, if you run across such issues, just reset the device’s Network Settings via “Settings>General>Reset>Reset Network Settings”. This will erase all saved Wi-Fi data, including passwords, so make sure you have a copy of the password. Another way is to forget the networks and establish a new connection. This option is available through “Settings>Wi-Fi>Select your connection>Forget this network”.

If these don’t work, you may want to look at your router and maybe reboot it.
