Last Update date : Feb 25. 2026

Keeping your Samsung Galaxy charged to 100% may seem like the best way to maximize usage, but lithium-ion batteries naturally experience more stress when they remain at their highest charge level for extended periods. Over time, that stress can contribute to gradual capacity loss.

Setting a maximum charge level below 100% allows your device to stop charging before reaching full capacity, keeping it within a more moderate range for everyday use. This can help reduce long-term wear associated with charging, especially if you tend to keep your phone plugged in overnight or for extended periods. This feature is ideal for users who want to prioritize consistent long-term performance while still having plenty of power for daily activities.
