How to Fix iOS 9 Lagging and Slow Performance on iPhone, iPad and iPod
1. Reduce Motion
Every new version of iOS comes equipped with a bunch of settings and configurable options that get buried away within the system. Some of these settings are extremely important, whereas others, such as the Reduce Motion integration, are user-specific and depend entirely on your own preference. By default, Reduce Motion is set to OFF, which means that the user interface is dynamic and animated throughout, this includes a gorgeous, subtle parallax effect on icons. Of course, this level of dynamic and animated behavior comes with a performance trade off for certain hardware.
To prevent the system from adding this level of effect to icons and other areas of the user interface you can enable Reduce Motion by heading to Settings > General > Accessibility > Reduce Motion, and toggling the switch to ON.
2. Reduce Transparency
Some of Apple's older devices may struggle to render the visual effects that iOS 9 wants to apply throughout. It's all well and good having these subtle, eye-catching features throughout the system, but when they significantly hinder the performance and experience received then it can become extremely frustrating. Thankfully, features such as transparency, which improves contrast on some backgrounds to increase legibility, can be enabled or disabled at will.
You can reduce the transparency of backgrounds within iOS 9 by heading to Settings > General > Accessibility > Increase Contrast, and then toggling the Reduce Transparency switch to ON.
3. Background App Refresh
The ability to allow applications to fresh their own content in the background isn't new to iOS 9. It's a small feature that is extremely beneficial to app developers who can provide their applications with the ability to go and fetch new content even when the application isn't active on the display. However, that level of functionality can be detrimental to the performance and battery life of the installed device.
Device owners can choose to enable or disable Background App Refresh by heading to Settings > General > Background App Refresh. When activated, there's also a great level of granularity offered that allows permissions to be granted on a per app basis.
4. Siri Suggestions
Siri has become ever more intelligent and capable as part of the iOS 9 refresh. That also means that Siri has become more power hungry and requires additional system resources as part of the assistant's deeper integration into iOS. Siri Suggestions suggests apps, people, locations, and a lot more when you search. This is even offered up before you start typing. This feature can be great for modern devices, but can cause issues for certain hardware. To disable Siri Suggestions navigate to Settings > General > Spotlight Search, and toggle the Siri Suggestions switch OFF. If you wish to leave it on, iOS provides the ability to remove apps from the search results.
5. Clean Installation of iOS 9 Using iTunes
Restoring a device is generally considered one of the last resorts when it comes to attempting to resolve performance issues that are being experienced after a new version of iOS has been installed. However, it's been found in the past that updating to the latest version of iOS via Apple's OTA update mechanism can sometimes cause issues. Connecting the device to iTunes and restoring it will provide a fresh installation of Apple's latest mobile operating system. Make sure to create a full backup of your data prior to doing this as everything will be wiped.
6. Restore iPhone, iPad or iPod as New
This is not ideal but the last resort. If you’ve setup your iOS devices by restoring from backup then the battery life problems could be due to some issue with the backup. Try to restore your idevices (Settings -> General -> Reset -> Erase All Content And Settings) and set it up as a new iPhone (not from the backup). But before you erase all the contents and settings, take a backup of your Apple devices using iTunes or iCloud, or selectively take a backup of your photos and videos using Dropbox or Google+.
Tips: Updating to new OS is never out of rick, and a large number of people suffered data loss during iOS 9 update, say, update fails, device goes to recovery mode, or data deletion for more update space.
