Every iPhone contains a lithium-ion battery that degrades over time.

This means that the battery will hold less of a charge than when new.

Apple Support pages reveal that the iPhone battery will typically drop to around 80% of its original capacity after 500 charges.

Users can check how their battery is responding to their charging habits by going to the Settings app and clicking on Battery.

Tap the battery status bar to access a new menu filled with information about your battery.

At the top of the Battery Health page is a data point called Maximum Capacity.

For iPhone owners with newer models like the iPhone 13, which comes with a larger battery, this number should always be at or around 100%.

But users of older models who have had to charge their device hundreds or thousands of times should note the risk of a degraded battery.

iPhones with aging batteries will require more frequent charging, further degrading the battery in an inevitable cycle.

Devices with severely degraded batteries can be prone to sudden shutdowns, according to an Apple support blog.

“When operations can no longer be supported with the full capabilities of the power management system, the system will perform a shutdown,” Apple wrote.

“While this shutdown is intentional from a device perspective, it may be unexpected by the user.”

There are ways to prevent battery degradation, including Optimized battery charging and strictly using Apple-made charging cables.
