If your iPhone battery percentage plummets by midday, background push services and location tracking are draining milliamp-hours.
Why This Problem Happens
- Background App Refresh running constantly for unneeded apps.
- Frequent location tracking by navigation and social apps in background.
Step-by-Step Troubleshooting Procedure
Step 1: Turn Off Background App Refresh for Non-Essentials
Objective: Reduce cellular radio wakeups.
- Open Settings > General > Background App Refresh.
- Toggle off individual apps like games, shopping apps, and streaming services.
Step 2: Audit Location Services to “While Using”
Objective: Stop constant GPS chip power draw.
- Go to Settings > Privacy & Security > Location Services.
- Change apps set to “Always” over to “While Using the App”.
Step 3: Enable Optimized Battery Charging
Objective: Preserve chemical battery health.
- Go to Settings > Battery > Battery Health & Charging.
- Enable “Optimized Battery Charging” or set the “80% Limit” on iPhone 15/16 series.
Verified Troubleshooting Tips
