How to Fix a Laptop Battery that Dies Fast?

Follow the tips below to fix your dying battery:

Step 1:

Replace Old Battery

If your laptop has an old discharging battery, then you need to change that first. However, removing the external battery is quite effortless and simple. 

In case your laptop has an internal battery, then you need to have to be a little techy to do that. All you need is to open the latch of your laptop, unscrew the battery and bring it out. 

Replacing the old battery can be done in the same manner. 

Make sure that the new battery you buy for your laptop must have sufficient life that can provide you long life. 

Step 2:

Reduce the Brightness

Adjust the brightness of your laptop to a minimum to improve battery life. It will consume less power and ultimately run the battery to the maximum. 

In the display settings, you will find options to reduce and adjust the brightness of your laptop. 

Step 3:

Battery Saver

Turn on Battery Saver! Go to battery settings in your windows and just select the right settings to get optimal performance of your battery. 


Step 4

Turn off the Keyboard backlight!

Latest laptops include backlit in their keyboards to allow easy typing. Especially when you use laptops in the dark. 

You have to turn off the backlight on the keyboard to extend laptop batteries and get the maximum life out of them. 

Step 5

Power and Sleep

In system settings, you’ll find power settings for power and sleep. Set the minimum time to turn off the screen automatically when your laptop is running on battery power. 

If you’re using the latest version of Windows like Windows 8, or Windows 10. Then you can change sleep settings in your windows. These settings will allow you to go to sleep mode when your laptop remains idle. 

Step 6

Keeps Laptop Cool

If your laptop is overheating with continuous use, then you have to keep it cool so that it does not affect the battery of your laptop and the laptop battery does not drain too quickly. 

Ensure the fan of your laptop is working fine and you should also close all unused applications on your windows to keep the power consumption of your laptop to a minimum. 

Step 7

Close Unused Programs

We generally run multiple programs simultaneously while using laptops but don’t actually use them side by side. This causes quick drainage of your laptop battery and consequently, it dies within hours. 

If you stop programs running in the background, then you can stop your laptop’s battery drainage and enhance the laptop’s battery twofold. 

You can do this from the Task Manager and closing down unused applications will definitely help. 

Step 8

Remove Unwanted Peripheral Devices

Using external peripheral devices like scanners, printers, Bluetooth headsets or external monitors with your laptop will drain your laptop battery quickly. 

Removing such external devices helps your laptop’s battery to last longer. Unplug all the redundant devices from the laptop to enhance the battery life of a laptop. 


The low battery life can be fixed by trying the above-mentioned methods. Stop doing things that will drain your battery. The battery capacity can be enhanced using different methods if your laptop has a bit potential to improve. Otherwise, replacing an old battery would be a wise idea.
