A. 1. Clear the app's cache by going to Settings > General > iPhone Storage. Find the Bosch Smart Gardening app and select 'Offload App'. This will remove the app but keep its documents and data. Reinstall the app from the App Store to clear any accumulated cache. 2. Ensure your iPhone has enough free storage space, as low storage can slow down app performance. Go to Settings > General > iPhone Storage to check and delete unnecessary files or apps.

B. 1. Close any background apps that may be consuming resources. Double-tap the home button (or swipe up from the bottom) and swipe away apps you are not using. 2. Restart your iPhone to refresh the system and improve loading times.
