🔋 Step 1: Check Battery Health

Know if your battery is naturally degraded or if something else is draining it.

Open Battery Report

Hold Option key and click the battery icon in the top-right corner. You'll see:

Condition: Normal, Replace Soon, Service Battery, or Service Now
Charge: Current % and max capacity

Interpret the Condition

Normal: Battery is healthy. Drain is likely from apps or settings.
Replace Soon/Service Battery: Battery capacity has degraded. Consider replacement after current cycle.
Service Now: Battery needs replacement urgently.

Battery Lifespan: Most MacBook batteries degrade to 80% capacity after 1,000 charge cycles (3-5 years). This is normal aging.

⚙️ Step 2: Review Power Settings

macOS has built-in features to extend battery life.

Enable Low Power Mode (macOS 13+)

System Preferences → Battery → Enable "Low Power Mode" when plugged in OR on battery.

Enable Optimized Battery Charging

System Preferences → Battery → Battery Health → Enable "Optimized Battery Charging". This slows charging to 80% to extend overall lifespan.

Reduce Screen Brightness

The screen is the biggest battery drain. Lower brightness significantly extends battery life. F1 key decreases, F2 increases.

📊 Step 3: Monitor App Battery Usage

Some apps drain battery faster than others.

Check Activity Monitor

Applications → Utilities → Activity Monitor. Click the Energy tab to see which apps use the most CPU/GPU (and thus battery).

Close Power-Hungry Apps

Chrome, video streaming, gaming, and rendering software drain battery fastest. Close them when not in use.

Disable Background App Refresh

System Preferences → General → Allow apps to run in the background when closed. Disable for non-essential apps.

🔌 Step 4: Disable Power-Draining Features

Turn off features you don't need to save battery.

Bluetooth: Turn off if not using wireless devices
WiFi: Disable if not needed (cellular or offline use)
Keyboard backlight: Disable or dim in System Preferences
Visual effects: System Preferences → Accessibility → Display → Reduce motion, transparency

🔧 Step 5: Battery Replacement

If your battery is degraded beyond acceptable use, replacement is the solution.

Battery Replacement Costs:

MacBook Air: $100-150 (parts only)
MacBook Pro 13": $120-180
MacBook Pro 16": $150-200
Apple Service: Add $50-100 labor

⚠️ Note: Most modern MacBooks have batteries glued to the case. Professional replacement is strongly recommended unless you have experience with internal repairs.
