Why does my Samsung phone battery percentage drop while charging?
A battery percentage drop while charging can occur for several reasons, primarily related to the phone’s operating system and battery management features. When you charge your phone, the device is simultaneously consuming power. If you are running demanding applications or features like high screen brightness, it can draw more power than the charger supplies, leading to a percentage decrease.
Additionally, older batteries may have reduced efficiency, which means they can struggle to hold a charge while being used and charged. Over time, battery health degrades, and it may lead to scenarios where you see a decline in battery percentage due to inherent battery issues.
Is it normal for the battery percentage to fluctuate while charging?
Yes, it is quite common for the battery percentage to fluctuate during charging. This is often due to the way the battery management system in your Samsung device operates. It may take a few moments after plugging in for the software to stabilize and provide an accurate reading. Sometimes a battery may seem to drop a couple of percentage points and then rise again, which is part of the normal charging cycle.
