Follow these three easy steps to find out your iPhone’s battery capacity:
Method 1: Use Third-party Apps
Several apps are available in the App Store that provide information about iPhone’s battery health. Download the Battery Life app using this iTunes link, which is available for free. You can remove the ads via an in-app purchase. When you launch the app it will show you the Battery Wear Level on the app’s Home screen itself.
Method 2: Settings App
Since iOS 10.2.1 or later, Apple has been issuing notices in the Settings > Battery section to inform users that their iPhone’s battery may need to be serviced using diagnostics in iOS. So launch the Settings app, and navigate to Settings to check if your iPhone battery needs to be replaced.
Method 3: Check Performance
The other method to find out if iOS has started slowing down your iPhone because your iPhone’s battery has degraded below 80% of its capacity. Download the Geekbench app from the App Store (download link) to check your iPhone’s benchmark scores.
Here’s are the Geekbench scores of the affected iPhones when they are new:
|iPhone 6 Geekbench Scores||1625||2918|
|iPhone 6s Geekbench Scores||2510||4360|
|iPhone 7 Geekbench Scores||3462||5595|
|iPhone SE Geekbench Scores||2423||4162|
If the Geekbench scores of your iPhone are significantly lower than the numbers mentioned above then it is probably due to the power management feature.
When Should You Replace iPhone Battery
According to Apple, you should consider replacing the battery only after the battery capacity is less than 80% of its original capacity. It also looks like the power management technique kicks in when battery capacity is degraded by 20%.
