If the battery of your laptop runs out quickly, the reasons for this can be very different: from simple battery wear to software and hardware problems with the device, the presence of malware on your computer, overheating, and similar causes.
This article details in detail why a laptop can be quickly discharged, how to identify the specific reason that it is discharging, how to increase its battery life, if possible, and how to save a laptop’s battery capacity for a longer period.

Laptop battery wear
The first thing you should pay attention to and check while reducing battery life is the degree of deterioration of the laptop battery. Moreover, this may be relevant not only for old devices, but also for recently acquired ones: for example, frequent discharge of the battery to zero can lead to premature battery degradation.
There are many ways to perform such a check, including the built-in tool in Windows 10 and 8 for generating a report on the laptop battery , but I would recommend using the AIDA64 program - it works on almost any equipment (unlike the previously mentioned tool) and provides all the necessary information even in the trial version (the program itself is not free).
You can download AIDA64 for free from the official site https://www.aida64.com/downloads (if you do not want to install the program, download it there as a ZIP archive and simply unzip it, then run aida64.exe from the resulting folder )
In the program, in the "Computer" - "Power" section, you can see the main points in the context of the problem under consideration - the passport capacity of the battery and its capacity when fully charged (ie, the original and current, due to wear), another item "Degree of deterioration »Displays how many percent the current full capacity is lower than the passport.
Based on these data, one can judge whether it is the wear of the battery that is why the laptop is quickly discharged. For example, the claimed battery life is 6 hours. We immediately subtract 20 percent from the fact that the manufacturer provides data for specially created ideal conditions, and then subtract another 40 percent from the resulting 4.8 hours (the degree of deterioration of the battery), 2.88 hours remain.
If the laptop’s battery life approximately corresponds to this figure during “quiet” use (browser, documents), then, apparently, there’s no need to look for any additional reasons besides battery wear, everything is normal and the battery life corresponds to the current state battery.
Also keep in mind that even if you have a completely new laptop, for which, for example, a battery life of 10 hours is stated, games and "heavy" programs should not count on such numbers - 2.5-3.5 hours the norm.
Programs that affect laptop battery drain
One way or another, energy is consumed by all the programs running on the computer. However, the most often reason that the laptop quickly runs out are startup programs, background programs that actively access the hard drive and use processor resources (torrent clients, automatic cleaning programs, antiviruses and others) or malware.
And if you don’t need to touch the antivirus, think about whether it is worth keeping the torrent client and cleaning utilities in startup - it’s worth it, as well as checking your computer for malware (for example, in AdwCleaner ).
Additionally, in Windows 10, in the Settings - System - Battery section, by clicking on the "View which applications affect the battery life" item, you can see a list of those programs that spend the most on the laptop battery.
You can read more about how to fix these two problems (and some related ones, for example, OS crashes) in the instructions: What to do if the computer slows down (in fact, even if the laptop works without visible brakes, all the reasons described in the article can also lead to increased battery consumption).
Power management drivers
Another common reason for the short battery life of the laptop is the lack of the necessary official hardware drivers and power management. This is especially true for those users who independently install and reinstall Windows, after which they use the driver pack to install the drivers, or do not take any steps to install the drivers at all, since "everything works like that."
Notebook hardware of most manufacturers differs from the “standard” versions of the same equipment and may not work correctly without the chipset drivers, ACPI (not to be confused with AHCI), and sometimes additional utilities provided by the manufacturer. Thus, if you did not install any such drivers, but rely on a message from the device manager that the “driver does not need to be updated” or some program for automatically installing drivers, this is not the right approach.
The correct path would be:
- Go to the official website of the laptop manufacturer and in the “Support” section find the driver downloads for your laptop model.
- Download and manually install hardware drivers, in particular the chipset, utilities for interacting with UEFI, if available, ACPI drivers. Even if the drivers are available only for previous versions of the OS (for example, you have Windows 10 installed, and available only for Windows 7), use them, you may need to run in compatibility mode.
- To familiarize yourself with the descriptions of BIOS updates for your laptop model posted on the official website - if among them there are those that fix any problems with managing power supply or battery drain, it makes sense to install them.
Examples of such drivers (there may be others for your laptop, but you can roughly guess what is required from these examples):
- Advanced Configuration and Power Management Interface (ACPI) and Intel (AMD) Chipset Driver - for Lenovo.
- HP Power Manager Utility Software, HP Software Framework, and HP Unified Extensible Firmware Interface (UEFI) Support Environment for HP Notebook PCs.
- ePower Management Application, as well as Intel Chipset and Management Engine - for Acer laptops.
- ATKACPI driver and hotkey-related utilities or ATKPackage for Asus.
- Intel Management Engine Interface (ME) and Intel Chipset Driver - for almost all notebooks with Intel processors.
Keep in mind that the latest Microsoft operating system, Windows 10, can, after installation, “update” these drivers, returning problems. If this happens, the instructions on How to prohibit updating Windows 10 drivers should help.
Note: if unknown devices are displayed in the device manager, be sure to figure out what it is and also install the necessary drivers, see How to install an unknown device driver .
Notebook dust and overheating
And another important point that can affect how quickly the battery runs out on a laptop is dust in the case and the laptop is constantly overheating. If you almost constantly hear the laptop fan cooling fan running wildly (at the same time, when the laptop was new, you could hardly hear it), think about fixing it, since even turning the cooler at high speeds by itself causes increased energy consumption.
In general, I would recommend contacting specialists to clean the laptop from dust, but just in case: How to clean the laptop from dust (methods for non-professionals are not the most effective).
Additional laptop discharge information
And some more information on the topic of battery, which can be useful in cases when the laptop is quickly discharged:
- In Windows 10, in “Settings” - “System” - “Battery” you can turn on battery saving (turning on is available only when using battery power, or after reaching a certain percentage of charge).
- In all recent versions of Windows, you can manually configure the power scheme, energy saving settings for various devices.
- Sleep mode and hibernation, as well as shutting down with the “quick start” mode turned on (and it is enabled by default) in Windows 10 and 8 also consume battery power, while on older laptops or in the absence of drivers from the 2nd section of this instruction can do it fast. On newer devices (Intel Haswell and newer), with all the necessary drivers, you should not worry about discharging during hibernation and completing work with quick start (unless you are going to leave the laptop in this state for several weeks). Those. sometimes you may notice that the charge is being spent on the laptop turned off. If you often turn off and do not use a laptop for a long time, while Windows 10 or 8 is installed, I recommend disabling Quick Start .
- If possible, do not let the laptop battery run out of power. Charge it whenever possible. For example, the charge is 70% and it is possible to recharge - charge. This will extend the life of your Li-Ion or Li-Pol battery (even if your old "programmer" of the old school says the opposite).
- Another important nuance: many heard somewhere or read that you can’t work all the time on the laptop from the network, since a constant full charge is harmful to the battery. This is partly true when it comes to storing the battery for a long time. However, if it is a question of work, then if we compare the work all the time from the mains and the work from the battery to a certain percentage of the charge followed by charging, then the second option leads to much more severe battery wear.
- On some laptops, there are additional options for battery charge and battery life in BIOS. For example, on some Dell laptops, you can select the work profile - “Mostly from the network”, “Mostly from the battery”, adjust the percentage of charge at which the battery starts and stops charging, and also select which days and time intervals use fast charging ( it wears out the battery to a greater extent), and in which - the usual one.
- Just in case, check for auto-enable timers (see Windows 10 turns on itself ).
That’s probably all. I hope some of these tips will help you extend the battery life of your laptop and battery life on a single charge.
