If what WheelieNick suggests doesn't help, you likely have some corrupt data in System Data, which may not clear the data from there. When this happens, it can be resolved, however, by backing up your iPhone, then restoring it from backup. Preferably using your computer, but you can do it on phone directly if you can't use your computer.

Hi there

Please try this

• Clear Safari Cache: Go to Settings > Apps > Safari, tap Clear History and Website Data, and select All History. 
• Offload Heavy Apps: Check Settings > General > iPhone Storage, then offload or delete apps like social media, web browsers, or streaming services that hide massive cache files under System Data. 
• Clean Message Attachments: Go to Settings > Apps > Messages > Keep Messages and change the time limit from "Forever" to 1 year or 30 days, or review large video and photo attachments manually. 
• Force Restart: Press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Apple logo appears.
