How to Change the Samsung Laptop Battery Limit (Step-by-Step Guide)

If you own a Samsung laptop, you might have noticed that your battery doesn’t charge to 100%. That’s not a defect — it’s actually a battery protection feature!
Samsung laptops come with a Battery Life Extender setting that limits charging to 85% to increase the battery’s lifespan.

In this guide, we’ll show you how to change or disable the Samsung laptop battery limit, whether you want to charge fully or adjust the limit manually.

⚙️ Why Samsung Laptops Limit Battery Charging

Samsung includes this feature to extend the overall battery life.
When the battery stays at 100% for long periods, it generates more heat and stress, which reduces its life.
By capping charging at 85%, Samsung ensures your laptop battery lasts longer.

✅ Important Point:
If you always use your laptop on a power adapter, keeping the battery limit ON is better for long-term health.

💡 How to Check If Battery Limit Is Active

Follow these quick steps to see if your laptop is limiting the charge:

Plug in your charger.
Check if the battery percentage stops at 85%.
If it does, your Battery Life Extender is enabled.

🔧 How to Change the Samsung Laptop Battery Limit

You can change the battery limit using Samsung Settings or Samsung Battery Manager, depending on your laptop model.

✅ Method 1: Using Samsung Settings (Most Common)

Click on the Start Menu and search for Samsung Settings.
Open the app and go to Battery and Performance.
Look for the option Battery Life Extender or Battery Protection Mode.
Toggle the option:
- ON → Battery stops charging at 85%.
- OFF → Battery charges up to 100%.

💡 Tip: If you don’t see this option, install or update the Samsung Settings app from the Microsoft Store.

✅ Method 2: Using Samsung Battery Manager (Samsung Galaxy Book Series)

Open Samsung Battery Manager from the Start menu.
Select Battery Protection Mode.
You’ll see an option like:
- “Limit battery charge to extend battery lifespan.”
Turn it off to allow a 100% charge.

✅ Method 3: Using BIOS Settings (For Some Older Models)

If you can’t find the option in Windows:

Restart your laptop.
Press F2 during startup to enter BIOS.
Navigate to Advanced → Battery Life Extender.
Change it to Disabled if you want full charging.
Save and Exit (usually F10).

⚠️ Caution: Make changes carefully inside BIOS.
