 If your Samsung phone’s battery percentage drops suddenly or shows inaccurate readings, it may be time to calibrate the battery. Calibration helps One UI display accurate charge levels, prevent unexpected shutdowns, and improve overall performance. Follow this step-by-step guide to safely and effectively calibrate your Samsung battery. 1. Understand What Battery Calibration Means Battery calibration doesn’t increase battery capacity — it simply ensures that the system software correctly recognizes the battery’s actual charge level. Over time, your phone might display 50% charge when it’s actually 40%, or shut down unexpectedly due to sensor misalignment. Calibration fixes these discrepancies so you can rely on more accurate battery readings. 💡 Note: Avoid third-party “battery calibration” apps. They can’t physically recalibrate your battery and might even harm your device. Did you know? For a complete guide on this topic, check out the Samsung Learning Hub and explo...
