iPhone Battery Health: Why It Matters and How to Monitor It

The battery health of an iPhone is an essential factor affecting its performance and longevity. Users who notice their iPhone battery draining faster than usual should investigate their battery health through the device's settings. The Battery Health and Charging section provides vital data, showing the battery's current capacity compared to when it was new. Over time, the battery capacity will decrease. When it drops below 80%, it indicates a significant decline in performance and a recommendation for battery replacement. Understanding this helps users maintain the phone's value, especially if they plan to sell it.
