How to Check the Battery Capacity on Your iPhone?

Whether your iPhone battery gives you a hard time or you are just curious, checking your battery health or capacity is always smart. iPhone batteries are designed to last longer, but at the end of the day, lithium-ion batteries have a limited lifespan, and their capacity will decrease over time. Apparently, “battery life” is the amount of time a battery runs before it needs to be charged again and “battery lifespan” refers to the amount of time a battery lasts until it needs to be replaced.

The battery lifespan is related to its chemical age and all lithium-ion batteries become less effective with the passing of time. After 500 full charge cycles, iPhone batteries can retain approximately 80% of their initial capacity. A single charge cycle is considered complete when the battery has been fully discharged. This gradual reduction in capacity occurs with each complete charge cycle, which may cause iOS to shut down your iPhone as a precautionary measure to protect its delicate electronic parts. 

The ability to assess your battery’s health will require an iPhone with the iOS 11.3 software or later, supported on any iPhone model from iPhone 6 onward. So, here's how you can check your iPhone’s battery health to ensure optimal working conditions.

How to assess your iPhone’s battery health?

1) Open Settings on your iPhone.

2) Choose Battery from the list.

3) Tap Battery Health.

You’ll be landed on a page that shows a link to more information about how lithium-ion batteries work, including details on peak performance capability.  

Maximum battery capacity, expressed as a percentage of battery capacity when it was new, is shown inside the section Maximum Capacity.  

Battery capacity will inevitably decrease over time, resulting in a few hours less usage between charges.   So, Apple-designed iPhone batteries retain up to 80% of their original capacity at 500 complete charge cycles when operating under normal conditions.

Under the Peak Performance Capability section, you can find information regarding your iPhone's battery health. 

  • Battery health unknown— : “This iPhone is unable to determine battery health. An Apple Authorised Service Provider can service the battery.”
  • Battery health degraded— When battery health has degraded to the point where replacing the battery with a new one will improve your experience, the following message appears: “Your battery’s health is significantly degraded. An Apple Authorised Service Provider can replace the battery to restore full performance and capacity.”
  • Normal performance— When the battery supports normal peak performance and the performance management protections have not been activated, the message reads: “Your battery is currently supporting normal peak performance.”
  • Throttled performance— “This iPhone has experienced an unexpected shutdown because the battery could not deliver the necessary peak power. Performance management has been applied to help prevent this from happening again.”
  • Throttling disabled— Manually disabling performance management, as explained in the following section, will show the message: “This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. You have manually disabled performance management protections.” 

A significantly worn-out battery is not a safety problem; you will experience more aggressive performance smoothing. Again, replacing the battery with an authorised replacement part will restore performance.

Do you feel that your iPhone battery is in poor health and needs a replacement? Well, you can get it done from any store and continue using your current phone.
