Step 1. Go to Settings > General > [Device] Storage.

Step 2. Delete unused apps or offload large files (e.g., videos) .

Fix 6. Disable Background App Refresh

Background App Refresh allows apps to update content even when you're not actively using them, which can consume significant data and contribute to slow iPhone internet performance.

Step 1. Go to Settings > General > VPN & Device Management and delete VPN profiles.

Step 2. Disable RCS via Settings > Apps > Messages > RCS Messaging.

Fix 8. Switch to LTE (4G)

While 5G promises faster speeds, coverage can be inconsistent, and your iPhone might struggle to maintain a stable connection in areas with weak 5G signals, resulting in slow internet.

Step 1. Open Settings > Cellular > Primary > Voice & Data.

Step 2. Select LTE instead of 5G Auto.

Fix 9. Forget and Rejoin Wi-Fi Networks
