How to Check Battery Health on Samsung Galaxy and Extend Its Lifespan

Unlike iPhones, Samsung Galaxy doesn't show battery health percentage directly in Settings — but there are ways to check it. Here's how to check your Samsung Galaxy's battery health.

Method 1: Samsung Members App (Official)

1. Open Samsung Members (pre-installed or download from Galaxy Store).
2. Tap Support → Phone Diagnostics → Battery Status.
3. Run the test — it shows whether the battery is "Good," "Normal," or "Replace."

Method 2: Hidden Diagnostic Code

Dial `*#0228#` or `*#*#4636#*#*` in the phone dialer. Some Galaxy models show battery capacity (current vs. original mAh).

Method 3: Samsung Service Center

Samsung Service Centers can provide a precise battery capacity reading (e.g., "4500 mAh remaining of original 5000 mAh = 90% health").
