Step 1: Check Battery Health

Batteries degrade over time. On iPhone: Settings > Battery > Battery Health. On Windows: Open Command Prompt and type "powercfg /batteryreport". If capacity is under 80%, it may need replacement.

Step 2: Screen Brightness

The screen is the #1 power consumer. Lower brightness to 50% or enable "Auto-Brightness". Using "Dark Mode" also saves power on OLED screens (most modern phones).

Step 3: Close Background Apps

Apps like Facebook or Maps track your location even when closed. Go to Settings > Privacy > Location Services and switch unnecessary apps to "While Using" or "Never".

Step 4: Enable Power Saver

Every device has a "Low Power Mode" or "Battery Saver". Turn it on! It limits background email checks and visual effects to squeeze out extra hours.

The “Lithium-Ion” Myth

You might have heard: “Let your battery drain to 0% before charging.” This is outdated advice from the 90s (Nickel-Cadmium batteries).

Modern Lithium-Ion batteries hate hitting 0%. It chemically stresses the cell.

  • Best Practice: Keep your battery between 20% and 80%.
  • Avoid: Leaving it plugged in at 100% for weeks (like a laptop that never moves). This causes “battery swelling.”

What is “Vampire Drain”?

If your laptop loses 20% charge overnight while “sleeping,” you have vampire drain.

  1. Windows: Instead of “Sleep”, use “Hibernate”. It saves your work to the SSD and cuts power completely.
  2. Mac: Check “Wake for Network Access” in System Settings and turn it off.

Pro Tip: Extreme temperatures kill batteries. Never leave your phone or laptop in a hot car in summer. Heat causes permanent capacity loss that cannot be fixed.
