How to speed up your iPhone (Expert Tips)

Is your iPhone running slower than usual? With regular use, iPhones can accumulate junk files, have memory issues, or get bogged down by iOS updates. 

There is a rumor that says that Apple intentionally makes the older models slower after releasing a new one. Well, the rumor can’t possibly be true. There are other factors that make your phone slow, so you might want to know How to speed up your iPhone.

The good news is there are many ways to give your iPhone a speed boost. Follow this comprehensive guide to learn expert tips, tricks, and steps to improve iPhone performance in 2023.

Why Has My iPhone Slowed Down?

There are several common culprits behind iPhone slowdowns:

Too Many Apps and Junk Files: The more apps and files you have, the more your iPhone has to load and process. Over time, unused apps, large photos/videos and system junk can congest storage and RAM, slowing things down.

Old Software: iOS updates aim to fix bugs and add new features, but they can also introduce new issues. Using an outdated OS is a major cause of lagging.

Low Storage Space: Your iPhone needs free space to manage memory and perform system tasks efficiently. With less than 500MB free, it will start slowing down.

Battery Issues: As iPhone batteries chemically age, they become less capable of providing peak power. This forces the iPhone to underclock the CPU to match the available juice, reducing speed.

Malware and Bugs: While rare, some apps or files may be corrupted and cause conflicts that hurt performance. Certain adware or malicious scripts can infect your iPhone and eat up resources in the background.

By identifying and addressing these common problems, you can get your iPhone’s speed back up again.

10.Restart Your iPhone

A simple restart can clear memory, end problematic processes and give your iPhone a fresh start, often restoring normal speed.

11. Update Apps

Ensure all apps are updated to their latest versions. Outdated apps may suffer from performance issues or bugs that are fixed in updates.

12. Reset Network Settings

If your iPhone seems laggy browsing the web or using apps, reset network settings under General > Reset to troubleshoot connectivity issues.

Using a Mac computer, connect your iPhone and open the summary tab in iTunes. Click “Check iPhone Storage Health” to scan for issues.

If your iPhone is still prohibitively slow after trying all other troubleshooting tips, a factory reset should get it back up to speed. Here is how to safely reset your iPhone:

Back-Up iPhone Data – To avoid losing photos, notes or other important data, back up your iPhone before resetting it. You can use iCloud backups or local iTunes backups.

Open Settings App – Go to Settings > General > Reset

Tap “Erase All Content and Settings” – This will initiate a full factory restore process.

Enter Passcode if Prompted – You may need to enter your passcode or Apple ID password to confirm the reset.

Wait for iPhone to Wipe – It will take several minutes for the reset process to fully complete. The iPhone will automatically reboot itself once finished.

Set Up iPhone as New – Follow the startup assistant prompts to set up your iPhone from scratch again. Skip restoring from backup during setup for best results.

Reinstall Apps and Data – Once your iPhone is reset up, you can selectively restore apps you want from the App Store and import data from your backup.

Be patient during and after the reset, it can take some time for performance to fully normalize again. But a fresh install should significantly improve any iPhone speed issues.
