Regardless of what iOS you use, you should consider the following tips to make your iPhone run faster:
- Get rid of things you don’t need. Look to see what you’re using (Settings > General > Usage) and consider removing clutter that you don’t use.
- Clear your browser’s cache. Improve performance by clearing your iPhone’s browser’s history, cookies and other data (Settings > Safari (or other browser) > Clear History > Clear Cookies and Data.
- Delete old text messages. Heavy SMS users can free up some space by deleting old conversations that are no longer needed. Open a chat, tap and hold on a sent message until “More…” appears, choose the messages you want to delete or tap “Delete all.”
- Turn off auto app updates. If speed and performance are your top priorities, this might be a good idea. Go to Settings > iTunes & App Store > Push all of the buttons to the left to turn off automatic downloads.
- Turn off location services. This tip will improve speed, increase battery life, and provide privacy. Go to Settings > Privacy > Location Services > turn off for apps that don’t need to know where you are.
