Why Is My Samsung Battery Draining So Fast? (Explained)

Why is my Samsung battery draining so fast

One slight issue can cause even a new Samsung battery to drain fast. Even if you have recently acquired a new Samsung laptop or have had it for a long time, you may be experiencing some trouble. You may be perplexed why your gadget isn’t performing as effectively as you would expect now or in the past. Here are some reasons why the Samsung battery is draining so fast.

Battery problems with your Samsung laptop can be caused by various factors, ranging from hardware failures to software malfunctions to regular wear and tear. It is feasible to improve the battery’s overall performance by resolving these potential issues.

Given that you are surprised at why your battery is draining so quickly, it is likely not functioning up to the standards you are accustomed to. Let’s look at some areas of concern that impact battery performance to determine why the battery may be draining so quickly and what may be done to potentially extend the battery’s life.

Laptop battery specifications

Your Samsung laptop might be equipped with various types of batteries, all of which are listed in the specifications. Every battery has a variable life expectancy in terms of how quickly it may be deemed to be depleting. For comparison purposes, the user manual for your laptop will include an approximate time range of operation based on your model number, which you may use to compare what you are experiencing to what you are used to.

It is common for batteries to last between 2 and 4 years in regular use before being replaced completely. If it has been longer than that, you may want to think about having the battery replaced instead. However, several issues may be present that you may address to restore your battery’s ability to survive for the length of time it was intended to.

Let’s have a look at some of the issues that might be causing your battery life to be compromised.

Why is my Samsung battery draining so fast?

Problems with the hardware

The performance of a laptop battery is dependent on the performance of all other components of the laptop. Therefore, the way you use your laptop directly impacts the amount of power required to run all of the many components required for optimal performance. If you are using your laptop for activities such as gaming or running multiple apps simultaneously, you will want additional power for it to function correctly. 

Keep in mind that the more processes you run, the greater the amount of battery life your laptop will lose due to the additional strain placed on the physical components of your laptop.

Problems with the software

It’s not uncommon for laptop battery life to be negatively impacted by the system’s overall performance. However, several factors might impact the system’s performance that you may not know about, like a software problem.

Problems caused by malware

A virus or an adware application causing your laptop to run slowly may have infiltrated your system throughout your laptop’s ownership. In addition, malware can attack your laptop’s graphics processing unit (GPU), resulting in a significant power drain. Often, there can be unnoticed processes in the background that actively corrupt other programs or steal sensitive information.


The manufacturer usually includes a pre-installed software bundle when you buy a laptop. Unfortunately, in many cases, this program is left running in the background while the user is away, draining your battery power without your knowledge.

Uninstalling apps you aren’t using will free up space on your computer, and you may do it with a variety of internet tools and operating system removal techniques. In addition, almost all computers include a built-in Task Manager application that lets you see what processes are consuming the most power. Consequently, you may be able to stop some of them from running if you don’t need to.

The Laptop’s Presets

Often, it is possible to reduce your computer’s power consumption by altering a few of its settings. First, look at the settings to see if your laptop has a power-saving mode. Next, you should check whether your laptop is set to run at maximum efficiency despite the drain it places on your battery. Most of the time, you can tweak this to your liking.

Screen brightness: The screen of a laptop is the most common source of battery depletion. When it comes to draining your battery, the most common cause is your screen’s brightness.

Even if you aren’t using your computer, some settings may be left in place. For example, turn off your wireless network and Bluetooth if you aren’t using them because they are still operating in the background, even if you aren’t.

How to fix the Samsung battery draining so fast?

Shut off any running programs: Close any running programs and applications and save any work you may be doing.

Unplug the adaptor from the wall jack: When the AC adapter is attached, Smart Battery Calibration will not be able to function.

Conduct the Samsung BIOS setup once the computer has been restarted: Restart the computer, and then hit F2 when the Samsung logo shows on the screen to exit. The Samsung BIOS Configuration will be launched as a result of this.

Start the automatic calibration of the battery: Double-click on Smart Battery Calibration in the right-hand menu and click Advanced in the left-hand menu. The battery will be drained as a result of the computer. A full charge can take five hours, depending on the battery size and how much time remains. Press the ESC key to end the process.

Charging the battery: Connect the AC adapter to your PC and recharge the battery when fully drained. The PC can be used immediately or left off with a completely charged battery until the battery is entirely recharged.

How long does Samsung laptop battery last?

Samsung laptops are equipped with Battery Life Plus, which allows you to charge and drain your laptop battery 1,500 times. For comparison’s sake, a normal laptop battery lasts around three years and 300 cycles before being replaced.


Hopefully, after following the above guides, your battery isn’t depleting that fast anymore. For the most part, you may use a software tool to uncover the root causes of battery depletion. However, a battery replacement is necessary if your laptop is still experiencing problems even after removing some of the current programs and turning off all unnecessary features.
