Is Your iPhone Battery Draining Too Fast? Here's When to Replace It

iPhone batteries, like those in any other smartphone, are consumables. Over time, they lose their ability to hold a charge, which can impact your iPhone's performance, causing it to heat up faster or even shut down unexpectedly. But how do you know when it's time for a battery replacement?

When to Replace Your iPhone Battery

Apple recommends replacing your iPhone's battery when its capacity drops below 80%. This means your battery can only hold 80% of its original capacity.

Here's a breakdown of battery life cycles:

iPhone 14 and older models: Batteries are designed to retain 80% of their capacity after 500 full charge cycles (under ideal conditions).

iPhone 15 and newer models: Batteries are designed to retain 80% of their capacity after 1000 full charge cycles (under ideal conditions).

How to Check Your Battery Health

1. Open Settings on your iPhone.

2. Scroll down and tap Battery.

3. Tap Battery Health.

You'll see information about:

Maximum Battery Capacity: The percentage of the battery's current capacity compared to its original capacity.
