Fix Fast Battery Draining Problem on Dell Inspiron, XPS, Alienware, Vostro, Latitude and Dell G Series Laptop

Overview: Today in this article we will learn how to improve the battery life on your Dell laptop. Many Dell users are facing fast battery draining issue so let’s learn to troubleshoot and optimize the battery life of Dell laptop batteries.

Let’s Start with Few Practical Scenarios

Scenario 1: Battery Drains in Minutes After 50%

I’m using Dell Inspiron 15R and I suddenly started having quick battery drainage issue two days ago. Normally, my battery lasts at least 4 hours after a full charge. But now all of a sudden, it has started draining in minutes. Battery seems to be charging normally. Last night, on 76% battery, it took just an hour for the battery to drain to 6%. Today, at 48% charge, it only took ten minutes for the battery to drain to 6%. This has never happened before. I’m not sure if it’s the windows or the battery itself. But it seems strange for a battery to go from normal to draining this quickly in a day. Note: I keep good care of the battery and almost never overcharge it. The system is running on Windows 10 currently. Any suggestion would be greatly appreciated!

Scenario 2: My Laptop Battery is Draining Fast Even After a Full Charge?

Hi, I am using DELL INSPIRON 7560 with windows 10 OS. From past few days, I am facing a problem with the battery i.e. Draining very quickly without using the laptop even after fully charged. Can anyone resolve what is the problem? Thanks…

Like the above two users, there are many Dell users who are facing fast battery draining issue. Let’s troubleshoot.

Run Hardware Test on Your Dell PC

Dell systems come with built-in ePSA diagnostics. In order to run the hardware test, start your PC and immediately keep on tapping F12 on the keyboard to go to the one-time boot menu. Select Diagnostic on the one-time boot menu screen to run the hardware scan. You can also run the diagnostic by pressing and holding the Fn on the keyboard and while holding the Fn key, power on the system, once it starts running the test release the Fn key.


In case you receive any error code, note down the Error code and validation code and run the remaining test. An error received while running the tests may indicate a hardware failure. Visit this link, enter the error code, validation code and the Dell service tag of your PC. This will let you know the exact hardware failure. In case all test passed, move on to the next step.

While running the Dell ePSA test if you receive error code 2000-0131 or 2000-0132 please visit the below link to troubleshoot further.

Understanding the Battery Life

The life of a battery depends upon the battery’s capacity like a number of cells and watt-hours. More number of cells or watt-hours will give you a long battery life when unplugged from a power outlet.

For example, a large 9 cell Battery with 90 Wh will have longer battery life than standard 4 cell battery 40-60 Wh. Battery with low capacity will wear out faster when compared to high capacity batteries because you have to charge it more frequently.

The real battery life also depends upon the usage and settings. You will start noticing a shorter battery life after 20-24 months and if you use applications on your laptop which consumes more power then you may notice shorter battery life before 20-24 months.

Turn Off Wi-Fi and Bluetooth When Not Required

The wireless card installed in your laptop utilizes more power and is one of the reasons for your battery drain. When not required turn off the Wi-Fi and Bluetooth to save battery power.

Limit Multitasking

Avoid multitasking, close all the background applications and keep only those app or browser open which you are using. Using fewer applications at a time will help the battery to last longer.

Avoid Using Apps Which Consumes More Power

Working on a word, excel, email or any documents will not have much impact than watching a movie or playing video games.

Use Power Saving Mode

  • Go to the notification area of the taskbar and make right-click on the Battery icon.


  • Select  Power Options.

Use Dell Quickset application for Dell Desktop Mode and Dell Longevity Mode

Keeping the charger plugged in all the time or not charging the battery completely may reduce the battery life. To make things easier Dell has come up with two battery charge settings i.e Dell Desktop Mode and Dell Longevity Mode which helps to increase the battery life. In order to avail this feature, you have to install the Dell Quickset application. Most of the times its preinstalled.

Unplug the External Devices

Unplug USB devices (such as external hard drive, USB flash drive, USB printer, etc.) connected to the laptop when you do not need it.

Close All Background Apps

Closing unnecessary apps running in the background can help the battery to last longer.

Reduce the Screen Brightness

The more bright is the screen, more is the usage of battery power. Decrease the screen brightness to run the system for a long time.

Make Sure Air Vents are Clean

Make sure air vents are not blocked and allow proper air flow to cool down the system, make sure air vents are clean. Dust and debris may block the air flow and the system fan will run constantly, struggling to keep the system cool and this will reduce the battery life. Keep system on a table or any flat surface where air vents are not blocked and allow proper air flow to cool down the system.
