Why does my laptop battery stop charging at 80%?

If your laptop battery stops charging once it reaches 80% it could be because the battery life extender is enabled. This feature prevents your laptop from charging up all the way to extend the life of your laptop battery.

Another reason may be that your laptop battery needs to be recalibrated. If your laptop battery is not properly calibrated, then your PC thinks the battery life is at a different percentage than it actually is. Follow the steps below to find out how to fix this issue.

How do I fix my laptop battery if not charging above 80%?

1. Disable battery limiter

  1. Click on Start and search for your laptop manufacturer application then hit Enter.
  2. Under System Tools, select Power or battery settings. Go to manufacturer app and open battery settings.
  3. Under Battery warranty & settings, make sure Conservation Mode is not enabled. Disable conservation mode to fix laptop battery not charging above 80.

This example is for a Lenovo laptop, but other laptop brands have a built-in app that provides users with further features and information about their devices. In this app, battery conservation tools and limiters can be enabled which prevents your laptop from charging to its full capacity.

2. Calibrate your battery

It’s important to not let your battery drain completely or leave it dead for a long period of time. Allowing your laptop battery to die or get extremely low will confuse the battery meter and may portray an inaccurate percentage.

Calibrating your laptop won’t fix a damaged battery or extend the battery life, but it will provide a more accurate reading of how much power your laptop has. For a more in-depth look at how to calibrate your laptop battery, we offer a guide on that as well.

Recalibrating your laptop battery is easy, simply let the battery drain from its full capacity to nearly dead. If your battery won’t charge further than 80%, then try leaving it plugged in for a couple of hours before allowing it to drain. Once it reaches a dangerously low percentage, plug it back in and charge it to full.

3. Remove all external devices

If you have other devices plugged into your laptop such as another monitor, keyboard, mouse, etc., try unplugging them. The more devices you have connected to your laptop, the longer it will take to charge up, or it may not even reach 100%.

Remove all devices from your laptop.
