7. Battery Health: Over time, the battery capacity of your iPhone 12 will naturally degrade. If your device is older or has been heavily used, it may not hold a charge as long as it did when it was new. Checking the battery health in the Settings app can give you an idea of the current capacity and overall health of your iPhone 12 battery.
Tip 5: Use Low Power Mode. This setting was introduced in iOS 9, and is one of the better options available for improving your iPhone 7 battery life. Enabling Low Power Mode will automatically adjust several settings so that your iPhone battery will last longer.
