Get the most out of your Galaxy Book Battery
Discover how to prevent your Galaxy Book battery lifespan from decreasing, even after prolonged use with these useful tips.
The technology inside a Samsung Galaxy book battery is designed to prevent the battery lifespan from decreasing even with repeated charging. This keeps the battery lifespan relatively constant, even after prolonged use, allowing you to enjoy your Galaxy book battery for longer.
Battery usage guide
Learn how to use and take care of your battery for safe and efficient usage.
• Use your product within the recommended temperature range (0 to 35°C). Charging the battery constantly or using the product at extreme temperatures can make the battery age faster. Do not place the product near open flames (fireplace, stovetop), inside heated cooking appliances, or near high-pressure vessels (such as pressure cookers).
• Always use an authentic Samsung charger. Using uncertified chargers can damage the battery and cause problems.
• Always use the authentic Samsung charging cable that meets the specifications. Using a cable that does not meet the specifications can damage the charging terminals.
• Connect the charger correctly. Incorrectly connecting the charger can damage the product.
• After reaching 100% charge, disconnect the product from the charger. Leaving the charger plugged in for too long may cause the battery to expand (swell).
• Charging while exposed to moisture can cause corrosion of the charging terminals and may damage the product.
• Do not subject the product to strong impacts such as dropping or puncturing. This may shorten the battery life or cause damage and failure.
• Do not disassemble or reuse the battery. This may shorten the battery life or cause damage and failure.

How to turn on Protect battery mode
Step 1. Open “Samsung Settings” and tap “Battery and performance”.

About battery aging
Batteries are a consumable item whose remaining life decreases with age. If you notice that you need to charge your battery more often than usual after a long period of use and that your usage time is noticeably shorter, have your battery checked by your local service center to see if it is time for a replacement as batteries lose life not only with use but also due to storage and environmental conditions.
Symptoms of battery aging
As your battery ages with use, you may notice a rapid decrease in battery capacity or power loss, even if the screen shows a high battery level. This is a feature of battery chemistry and is common in lithium-ion batteries.
If you are experiencing difficulty using your product due to the battery aging over time, please have your battery checked by a service center for assistance with a replacement.
Especially in low-temperature environments or during the winter, aging batteries may experience power outages. This may occur with increasing frequency depending on the level of battery aging.
Running high-end features like games can age the battery by affecting the instantaneous power supply, which causes the device to feel slower and less responsive.
