How to make your laptop battery last longer

• Lower screen brightness. The screen uses the most power.
• Turn on Battery Saver from the battery icon.
• Close apps you are not using.
• Avoid keeping the charger plugged in at 100% all day if you can.
• Do not let the battery drop to 0% often.
• Keep the laptop away from heat; heat damages batteries.
• Use the original charger. Cheap chargers can harm the battery.

If backup is under one hour on a laptop that used to give three, the battery probably needs replacing.
