If your iPhone’s battery life seems to be getting shorter and shorter, it might be time to check your iPhone’s battery health. All iPhones ship with batteries that are designed to last for years, but depending on how you typically recharge your iPhone’s battery, the battery’s capacity can be reduced early leading to shorter battery life. Checking your iPhone’s battery health can help you keep an eye on things and make sure your iPhone’s battery isn’t defective.

Tip: Your iPhone’s battery is designed to last for up to 500 charge cycles. A charge cycle is one full charge and discharge of the battery. Apple says that your battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles. Apple can replace old and defective batteries.

Here’s how to check your iPhone’s battery health:

From the iPhone’s home screen, tap Settings.
Tap Battery.
Tap Battery Health.
Your iPhone’s battery health is displayed on the screen, as shown below.

Tips for Maintaining Your iPhone’s Battery Health

Here are some tips for maintaining the health of your iPhone’s battery:

Enable Optimized Battery Charging setting, as shown in the screenshot above. This setting smartly charges your battery to reduce premature aging. (This setting is enabled by default.)
Try not to drain your iPhone’s battery below 20% before recharging.
Don’t store your iPhone in extreme temperatures. Ideally, the battery would always be kept at room temperature.
When storing your iPhone for a prolonged period of time, discharge the battery to around 50%-80%, turn off the iPhone, and keep the charger unplugged.
