A. 1. Clear the app cache: Go to your iPhone's Settings > General > iPhone Storage. Find the Santander Cycles app and tap on it. If there's an option to 'Offload App', do that to clear cache without losing data. Reinstall the app afterward for a fresh start.

B. 2. Close background apps: Double-click the Home button (or swipe up from the bottom of the screen on newer models) to see all open apps. Swipe up on the Santander Cycles app and any other apps you are not using to free up resources.
