6 Upgrade to the Latest Version of iOS
If you’re still running an older iOS version, your iPhone will definitely be slower. Newer iOS versions are optimized for speed and also deliver newer features, like the recent beta version of Battery Health.
Even iOS 12 (which will be released in the fall of this year) has proven to help speed up older iPhone models.
