1. Make your phone run faster by clearing up RAM.
2. Make your phone run faster by clearing the cache.
3. Erase old text message threads
If you never delete any text messages (or multimedia messages like pictures and video), it can weigh down the phone’s software. One easy way to make sure old messages don’t clog up your phone is by changing the default amount of time you keep messages: the iPhone offers 30 days, 1 year, and forever.
To do this go to Settings > Messages > Keep Messages.
4. Close All Nonessential Apps
Background apps (whether refreshing or not) do take up iPhone memory. The middle ground viewpoint to both save on battery and memory is to close all nonessential apps but leave open the ones you consistently return to throughout the day. That way your iPhone will use less battery opening up those essential apps and save on memory when you close out a game you’re finished playing, or a social media feed you don’t need to check again for awhile.
To do this, double click your Home button to activate the app switcher. Swipe up to close out any nonessential apps
5. Make Your iPhone Faster by Clearing Safari Cookies & Data
Treat your iPhone like you would a computer. This means you need to empty Safari’s cache to keep it running smoothly.
To do this, head over to Settings > Safari, and tap “Clear History and Website Data.”
6. Turn off automatic downloads
Similar to automatic updates, automatic downloads can also bog down your iPhone. If you have automatic app updates turned on, an app that you’ve downloaded on your iPad could automatically begin installing on your iPhone. While useful, it can certainly make your phone a little slower.
To turn it off, navigate to Settings > iTunes & App Store. Switch the sliders to off mode.
7. Disable background refresh
There are some apps that you definitely want to be refreshed in the background. For example, email apps should be able to download new content and navigation apps should refresh when you minimize them as well. But the majority of the apps on your iPhone simply don’t need to refresh when they’re not on your screen — all they’re really doing is slowing things down and hurting your battery life.
To do this, Go to Settings > General > Background App Refresh and go through the list. Toggle as many apps as you can to the off position. Note that push notifications will still work just fine for all your apps, even if you disable background refresh.
