The iPhone 13 has a 3,240mAh battery designed for all-day use. If your battery is draining faster than expected, these steps will help identify and fix the problem.
Step 1: Check Battery Health
Step 1
Go to Settings → Battery → Battery Health & Charging.
- 80-100%: Healthy battery
- 70-79%: Some degradation — expect slightly reduced life
- Below 70%: Battery should be replaced
The iPhone 13 is designed to reach 80% capacity after 500 charge cycles (2-3 years of normal use).
Step 2: Identify Battery-Hungry Apps
Step 2
Go to Settings → Battery and check which apps consumed the most power.
- Social media apps (Instagram, TikTok, Facebook) are top culprits
- Games and video streaming drain battery quickly
- Look for unfamiliar apps using excessive battery
Step 3: Disable Background App Refresh
Step 3
Go to Settings → General → Background App Refresh.
- Turn it off completely for the biggest battery boost
- Or set to Wi-Fi only (not cellular)
- Disable it for specific battery-hungry apps
Step 4: Turn On Low Power Mode
Step 4
Go to Settings → Battery → Low Power Mode or add it to Control Center.
- Reduces processor speed and background activity
- Can extend battery life by 1-2 hours
- Automatically enables at 20% battery
Step 5: Reduce Display Brightness
Step 5
The display is one of the biggest battery drains:
- Enable Auto-Brightness: Settings → Accessibility → Display & Text Size
- Reduce screen timeout: Settings → Display & Brightness → Auto-Lock (30 seconds)
- Use Dark Mode: Settings → Display & Brightness → Dark
Step 6: Disable Location Services
Step 6
GPS drains battery even when you're not actively using it:
- Go to Settings → Privacy & Security → Location Services
- Set apps to "While Using" instead of "Always"
- Disable location for apps that don't need it
Step 7: Check Mail Fetch Settings
Step 7
Go to Settings → Mail → Accounts → Fetch New Data.
- Set to "Manually" or "Hourly" instead of every 15 minutes
- Push email constantly drains battery
Step 8: Update iOS
Step 8
Go to Settings → General → Software Update.
- Apple releases battery optimization updates regularly
- Make sure you're on the latest iOS
Step 9: Reset Network Settings
Step 9
A corrupted network connection can drain battery:
- Go to Settings → General → Transfer or Reset → Reset
- Tap Reset Network Settings
- You'll need to reconnect to Wi-Fi
