Laptop batteries wear out faster in heat. These five habits help them last.
1. Keep it between 20% and 80%
Many laptops have a battery care mode that stops charging at 80%. Turn it on if you work plugged in most of the day.
2. Lower the brightness
The screen is the biggest power user. Dropping brightness from 100% to 60% can add more than an hour.
Tip: Avoid using the laptop on a bed or pillow. Blocked vents raise the temperature and age the battery.
