Search Settings for Faster Changes
Finding the right setting is a pain on the iPhone and iPad on iOS 8, but it gets better in iOS 9. The new iOS update lets you search the settings with a pull down option from inside the Settings app.
This is an awesome upgrade that will help you solve your own iPhone problems faster once you upgrade to iOS 9. One downside is that if you don't know what Apple calls the feature or option you want to change the results may not help.
Apple also adds new Settings options for the battery so you gain faster access and more control over battery life.
