Lenovo is one of the biggest names in the PC manufacturing space.
Its laptops are affordable and pack some of the most advanced specs for the money. In this article, we discuss how long Lenovo laptop batteries last.
We’ll also be giving you some tips on how to prolong your battery’s life. Let’s begin.
How Long Does a Lenovo Laptop Battery Last?
Lenovo batteries can last up to 10 hours after a full charge. However, like all Lithium-Ion batteries, they wear out eventually. Gradually, they lose their ability to hold a charge. Nevertheless, your Lenovo laptop battery has an average lifespan of 2 to 4 years.
Why Is My Lenovo Laptop Battery Draining Fast?
Battery discharge is a common problem faced by all laptop brands (including Lenovo). Below are a few reasons your battery doesn’t last long:
1. Background Apps
A laptop allows you to open multiple apps simultaneously. However, some of these apps are power-hungry. Some apps require high processing power and screen resolution.
If you don’t close power-sapping apps running in the background, it would shorten your laptop’s runtime.
2. Bright Display
Aside from having the best processing speed or a large hard disk, your laptop screen is very important. That said, increasing the brightness of your screen has downsides.
While a bright display improves visuals, it reduces your battery’s life. You should only do this when your laptop is plugged to an outlet.
3. Online and Network Connections
Having access to the internet, connecting to external hardware (through Bluetooth or Wi-Fi) is an important requirement for laptops.
But these simple connections can drain your battery when you allow them to run for extended periods.
It’s best if you put them off when they’re not in use.
4. Software Problems
For apps and operating systems on your laptop, there will always be upgrades to improve the previous version. However, if it’s not done correctly, it would drain your battery.
Most of these upgrades may require more processing power, which drives up energy consumption.
5. Hardware Issues
Sometimes, the fault may not be coming from your screen’s brightness or the apps on your laptop. It could be from other hardware on the laptop.
You must notice this hardware defect in time. If you don’t, you may spend time and money on the wrong thing.
Should I Use My Lenovo Laptop While Charging?
You won’t have any problems using your laptop while it’s charging. Even if the battery is 100% full, you can still use it while it’s plugged to the mains power.
Lenovo laptops can route power. In other words, after your battery is full, it connects you to the mains power, so your battery will stop charging.
Hence, you’re no longer using your battery’s energy. You’re connected to the mains.
At What Percentage Should I Charge My Lenovo Laptop Battery?
To avoid damaging your Lenovo laptop battery, it’s best if you keep battery levels between 40 to 80 percent. This would help you prolong your battery’s life.
How? Each cell in your lithium battery responds to voltage levels. The higher the charging percentage, the greater the voltage levels.
The higher the voltage levels, the more stress on the cells as they try to store this energy.
If you maintain your charging percentage between 40 to 80 percent, you’ll have fewer discharges.
How Do I Know If My Laptop Battery Needs Replacing?
Lenovo batteries tend to last longer than many laptop batteries in the market. As they get older, their capacity begins to decrease.
Here are a few ways to know when your battery needs to be replaced:
1. Windows Notification
Except for cases of discharge (low battery notifications), Windows doesn’t update you on your battery levels.
Eventually, your battery will reach a level where Windows will warn you. You’ll notice the red X on your battery’s icon.
When you click on it, the notification will show you need to replace your battery.
It will also let you know that your battery would shut down at any moment. This is because your battery wouldn’t last long, except it’s connected to a power source.
2. Short Run Time
This is one of the major signs you will notice about expired batteries. On average, your battery is supposed to last for 6 hours.
If you notice that your battery now lasts up to two hours (or less), you need to consider replacing it.
3. Power Related Issues
It’s normal to experience a few glitches now and then. However, if you continue to experience this issue frequently, your battery may be faulty.
If your laptop shuts down unexpectedly, maybe your battery has lost its power to store energy. Hence, it needs to be replaced.
4. Slow Charge
Lenovo batteries charge quickly and also retain their energies for a long time. Slow charging may be a sign that your battery needs replacement.
To be sure, remove your charger and plug it in again. If the problem persists (over time), you may need to change your battery.
Because of the multiple tasks carried out by your laptop, it may get hot. But laptops have a way of cooling themselves.
If you notice your laptop is hotter than usual, your battery is probably working too hard. It’s finding it difficult to cool itself.
Most of the time, your laptop fan may get too noisy because of this. To avoid further damage, replace your battery.

Are Laptop Battery Chargers Interchangeable?
Laptop batteries can be interchangeable if the adapter’s wattage and connector tip corresponds with your laptop.
A laptop battery requires a certain amount of power to charge properly.
Your charger (AC adapter) converts the high voltage received from the outlet into DC required to charge your battery.
Failure to meet up to the wattage requirement can lead to hazardous circumstances.
Why Does My Lenovo Laptop Battery Not Charge?
If you’ve seen the “plugged in, not charging” notification on your laptop, don’t panic. This is quite common for many users.
You need to know the actual cause of this problem. It could result from a faulty battery or an outdated battery driver.
For cases of faulty batteries and outdated drivers, buy a new battery and update your drivers.
The problem could also be from your adapter. Most of them lose their functionalities under certain voltages.
If the issue persists, you could reset your laptop. It has been proven to work most of the time.
Just switch off your computer, remove the battery, and unplug your power cord.
Hold your power button for 30 seconds (this is to ensure that there’s no power left in your laptop). After doing this, replace your battery, plug your charger, and turn on your computer.
It’s also important you check your threshold. Most Lenovo laptops have a program that stops your laptop from charging after a certain level.
If you want to disable this feature, check the power settings on your Lenovo laptop. Select the custom threshold and disable it.
