Reasons Your Laptop Battery Is Draining Fast

Laptop battery draining too fast? Here’s how to fix.

Laptop batteries are meant to last for years, but many users find that their laptop battery drains too fast within just a few months of use. There are various factors that can cause excess battery drainage, from software issues to hardware problems. Here are some of the most common causes of fast battery drain and how to fix each one.

Power Settings

The power settings on your laptop can have a big impact on battery life. Make sure you have your power plan set to optimized or balanced settings, not high performance mode. Open the power settings menu and adjust the sleep and screen brightness settings to lower levels. You can also disable features like keyboard backlight and touchpad illumination when running on battery power.

Applications Running in the Background

While you are operating your laptop and are working on a specific task/application, there might be a lot of unwanted programs and applications that are running in the background, thereby draining your laptop’s precious battery without actually giving you anything in return. To fix this problem, you need to perform the following steps:

  1. Open up task manager on your PC and select the startup apps tab.
  2. Check the list of the apps that are set to “Enabled” as those are the ones that start up when your computer boots up.
  3. If you think that there are some apps/tasks which definitely need to work in the background, keep them up and running, but disable apps that you don’t need running in the background.

Connected Devices

Devices connected to your laptop like a wireless mouse, Bluetooth speakers, or USB drives will continue to use power even when idle. Disconnect any external devices you are not using to reduce battery drainage. Make sure to safely remove USB drives from the system tray before disconnecting them.

WiFi and Network Connections

Keeping an active WiFi or Bluetooth connection open will drain your battery faster. Only enable these connections when needed and turn them off when you don’t need an internet connection. You can also adjust the power mode for WiFi and Bluetooth adapters to reduce power usage.

Managing Backlit Keyboard to Save Battery

The keyboard backlight is a convenient feature for working in low light conditions but can also be a significant drain on your laptop’s battery if not managed properly. Here are strategies to optimize its usage and save battery life:

  • Adjust the backlight settings: Most laptops allow you to control the intensity of the backlight. Use the function keys (often marked with symbols like a sun or light bulb) to adjust the backlight to the lowest comfortable setting. Lower brightness consumes less power.
  • Set a timer for backlighting: Some laptops come with settings that let you control how long the backlight stays on when inactive. Set the backlight to turn off after a short period of inactivity, such as 30 seconds or 1 minute.
  • Turn off the backlight during the day: In well-lit environments, turn off the keyboard backlight entirely. It’s an easy way to conserve power when the extra visibility isn’t necessary.

Hardware Issues

Over time, the major components that impact battery life like the battery itself and the charging circuit can degrade. If software solutions don’t fix fast battery drain, you may need to run a battery diagnostic test or even replace your laptop battery. Other hardware issues like a loose cable or damaged charger port can also cause excess battery drainage.

Battery Maintenance Tips

Regular maintenance can extend your laptop’s battery life significantly. Here are a few tips:

  • Calibrate your battery regularly: This involves letting it run from 100% down to 0%, then charging it back to 100% in one go. This helps keep the battery’s meter accurate.
  • Keep your laptop cool: Excessive heat can degrade your battery faster. Use your laptop on hard, flat surfaces and consider using a cooling pad.
  • Update your BIOS and drivers: Sometimes manufacturers release updates that improve battery performance and efficiency. Keeping your system up-to-date can help minimize power issues.

Understanding Battery Cycles

Understanding the concept of battery cycles can help you better manage your laptop’s battery health. A cycle counts as using 100% of your battery’s charge, but this doesn’t necessarily mean from 100% down to 0%. It could be from 50% to 0% and then from 100% to 50%, which counts as one cycle. Most batteries have a limited number of cycles before their capacity begins to deteriorate.

Energy Saving Accessories

Invest in accessories that can help conserve battery life:

  • Portable laptop chargers: These can provide you with extra power without needing a power outlet, ideal for travel or long commutes.
  • Energy-efficient external devices: Opt for peripherals that require less power or have their own power source.

Software Optimization

  • Browser usage: Some web browsers are more energy-efficient than others. Experiment with different browsers to see which ones use less battery.
  • Battery saver modes: Most operating systems offer a battery saver mode that automatically limits background activity and reduces power consumption when your battery reaches a certain threshold.

When to Seek Professional Help

If you’ve tried all the above tips and your battery still drains too quickly, it might be time to consult a professional. This section could discuss:

  • Signs that you need professional help: Unusually fast drain even after replacing the battery, system shutdowns, or battery swelling.
  • Choosing the right service: Tips for finding a reputable technician or service center and what to expect during a professional battery check-up or replacement.

Conclusion

In summary, check your laptop’s power settings, end unnecessary running applications and processes, disconnect external devices when not in use, and disable WiFi and Bluetooth when possible. If the problem persists, there may be an underlying hardware issue that requires further troubleshooting or repair. With some tweaks and adjustments, you should be able to optimize your laptop’s battery life and fix fast battery drain issues.​
