What Does Your iPhone Battery Health Mean? 

The Battery Health section shows the remaining battery capacity of your iPhone, among other important breakdowns of battery health. According to Apple’s description, the Maximum Capacity provided is “a measure of battery capacity relative to when it was new. Lower capacity may result in fewer hours of usage between charges.” So, the closer your device battery is to 100%, the better.

So if it’s above 80%, your battery is considered good, but when the battery falls below this level, it’s considered worn, and you should consider getting a replacement because it’ll degrade much faster.

The Peak Performance Capability section will show you a more detailed explanation of your battery’s performance. Here’s what they all imply: 

  • Your battery is currently functioning at peak performance levels: This indicates that your battery is operating normally and has full capacity. To maintain this level of performance for an extended period, there are a few steps you can take to ensure the health of your iPhone’s battery.
  • As your iPhone battery undergoes chemical aging, the built-in dynamic software and hardware are designed to mitigate any potential performance issues that may arise. When your battery starts to degrade, you may receive a message indicating that its performance could be affected.
  • This iPhone has encountered a sudden shutdown due to the battery’s inability to provide the required peak power. Performance management has been activated to prevent future incidents: This notification suggests that your battery is causing problems for your iPhone, indicating that it may be time for an upgrade. You may experience performance issues such as slower loading speeds.
  • Your battery’s health has greatly diminished. When its capacity falls below 80%: Your iPhone will show this warning, which may greatly impact your phone’s performance.

How to Check iPhone Battery Health

Here’s a quick guide to walk you through the simple steps on how to see your iPhone battery health:

  1. Open the “Settings” app on your iPhone.
  1. Scroll down and tap on “Battery”.
  1. Tap on “Battery Health”.

  1. Here, you’ll see your device’s maximum battery capacity and peak performance capability. Maximum battery capacity indicates the battery’s health, with 100% being optimal. Anything less may suggest the battery is wearing out and may need to be replaced.
  1. You can also see if your device is currently supporting Peak Performance Capability. If Peak Performance Capability is disabled, it may be due to an unexpected shutdown in the past. You can enable it by tapping on “Disable” and following the on-screen instructions.
  1. In addition, you can check your battery’s cycle count, which indicates how many charge cycles your battery has gone through. A typical iPhone battery is designed to retain up to 80% of its original capacity after 500 complete charge cycles.

When To Replace an iPhone Battery?

If you check and find out that your battery health has dropped below 80%, then you may want to consider replacing the battery. Similarly, if you notice your battery performance is below the normal standard, you should change it.

In addition, you can find the warning of your battery health being degraded under the  “Battery Health & Charging” section. So, if your phone is giving you problems such as unexpected shutdowns and/or inability to sustain peak performance, you should check the battery’s health and take further action. According to Apple, iPhone batteries are “designed to retain over 80% of its original capacity at 500 complete charge cycles when operating under normal conditions.”

The good news is that, replacement of bad batteries is covered under the 1-year additional warranty or with AppleCare for residents in the US. However, if your phone is no longer under warranty coverage, Apple charges a fee of around $69-99 for the iPhone battery replacement service.

Meanwhile, when your iPhone battery drops below 80% of its original capacity, you can use the  “performance management” feature, which in some models may automatically switch On. The feature helps in preventing unexpected shutdowns. However, you can turn the performance throttling off anytime you want. Just find the small “Disable” icon at the end of the text below “Peak Performance Capability,” and switch it off.

As soon as you receive a message or notification that says battery health is degraded or unknown, visit the nearest Apple Store to get a certified Apple battery replacement. Likewise, you can contact Apple Support, or head to an Apple Authorized Service Provider to get a new battery.
