The length of time that laptops can remain without needing to be charged depends on how powerful it is and the capacity of the battery. Users can get more information on the status of their battery by running a battery report. A laptop battery can drain faster depending on what tasks you’re doing. For instance, playing games that demand more resources will drain power faster. If you’re looking for easy methods to improve your Windows 11 battery life, we have a guide.

Why does my laptop battery stop charging at 80%?

Here are a few reasons the laptop battery does not charge fully:

Misconfigured battery settings: If the power settings are misconfigured, for instance, the Batter Life Extender is enabled, the battery won’t charge beyond 80%. Requires calibration: When the battery has not been calibrated for long, it doesn’t correctly judge the charge percentage and, as a result, the HP laptop battery stops charging at 80. Hardware issues: Batteries physically damaged or ones with a hardware malfunction, too, show such errors.

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

Here’s what you should di first:

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%.

1. Disable the battery limiter

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 not to let your battery drain completely or leave it dead for a long 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%, try plugging it 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 full.

3. Run power troubleshooter

Running the power troubleshooter will scan your laptop for any issues or problems with your battery. If the troubleshooter detects anything wrong, chances are the laptop battery not charging above 40 issue is solved. SPONSORED

4. Update the battery driver

Regularly updating battery drivers will reduce the likelihood of running into laptop battery issues, including the inability to charge past 80%. If you have the latest driver version and the issue is not solved, move on to the next solution.

5. Uninstall and re-install the battery driver

Uninstalling and reinstalling your laptop’s battery driver may solve the issue. If your driver is corrupted or damaged, uninstalling will help fix it. Once you uninstall the driver and restart your PC, the driver will automatically be installed again. Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions.

6. Replace the battery

If you’ve tried every solution and nothing has fixed your laptop battery, it may be a good indication that it needs to be replaced. This is most likely the case for older laptops or ones with detachable batteries. Users can bring their laptops to a computer repair store or purchase one from the manufacturer’s website. If you have a newer laptop that is still within its warranty, you can run a battery report to provide proof of an issue with your battery.

How do I change power modes in Windows 11?

Users can choose between the best power efficiency, balanced, and performance power modes. If you want to prioritize the life of your battery over performance, then change the power mode to the best power efficiency. To prioritize performance over the battery, adjust the mode to the best performance. We hope one of the above solutions helped you fix your laptop battery if it’s not charging above 80%.
