1️⃣ Reduce Screen Brightness

Your screen is the biggest battery drainer.

👉 Lower brightness to the minimum comfortable level.
👉 Use auto-brightness if available.

Example:
Reducing brightness from 100% to 60% can extend battery life by 30–40%.

2️⃣ Use Power Saving Mode

Always switch to Battery Saver / Power Saver mode when unplugged.

👉 Windows: Settings → Power & Battery → Battery Saver
👉 macOS: System Settings → Battery → Low Power Mode

Example:
Background apps pause automatically, saving power.

3️⃣ Close Unused Apps & Browser Tabs

Apps running in the background silently drain battery.

👉 Close unused software
👉 Limit Chrome/Edge tabs
👉 Avoid heavy apps when on battery

Example:
Closing 10 unused browser tabs can save 10–15% battery per hour.
