FAQs
How do I keep my laptop battery healthy?
There are several ways to keep your laptop battery healthy:
1. Keep the battery charged: It’s a good idea to keep your battery charged above 20% as much as possible. This will help prevent it from fully discharging, which can be hard on the battery.
2. Avoid extreme temperatures: Try to keep your laptop in a cool, dry place. Extreme heat or cold can damage the battery over time.
3. Unplug your laptop when it’s fully charged: Once your laptop is fully charged, unplug it from the charger. Leaving it plugged in all the time can cause the battery to degrade faster.
4. Use your laptop on battery power occasionally: Using your laptop on battery power occasionally can help keep the battery healthy by exercising it.
5. Calibrate your battery: If your laptop has a removable battery, you can calibrate it by fully discharging and recharging it. This can help improve the battery’s accuracy when it comes to displaying remaining charge.
6. Update your laptop’s software: Make sure you’re using the latest version of your laptop’s operating system and any relevant device drivers. This can help improve the performance of the battery.
7. Use a high-quality charger: Using a high-quality charger can help prevent damage to the battery. It’s also a good idea to avoid using third-party chargers, as they may not be as reliable.

3. Running multiple programs at once: Having multiple programs running at the same time can also drain your battery faster.
4. Using the laptop while it’s charging: Using your laptop while it’s plugged in can drain the battery faster, as the charger has to work harder to keep up with the power demands of the device.
