How to check the battery health of iPhone and iPad most accurately? In the past, many people recommended using Battery Percentage , a battery health app downloaded from the App Store . However, this battery query tool can only be used as a reference. It will be a little different from the battery health tested by Apple. If you are still worried The device in my hand feels very laggy recently, and I wonder if the battery has aged. Through this tutorial, I can use the most accurate online query method from Apple’s original factory to check the most accurate battery life. Avoid the awkward situation of being told that the battery is still in good health and cannot be replaced when the device is about to be replaced.
Note that iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus and newer devices will have battery health lower than 80% due to the power management technology added by Apple. The performance of the processor will be significantly reduced, and it will feel very stuck when using it. This is obviously a warning sign of battery aging.
In addition, Apple’s official website reminds that after the battery cycle exceeds about 500 times, the battery capacity will continue to be consumed, which will affect the battery life.
Now there is no need to go to the Apple Direct Store (Taipei 101) to make an appointment to check the battery health. You can check directly through the official website at any time, avoiding a wasted trip. We also remind some users to use other third-party software to compare accuracy. This is an inaccurate comparison method. Apple checks the battery based on this test, not through other third-party tools.
iOS 11.3 (inclusive) and above devices have built-in “Battery Health” query function. For detailed instructions, please read ” How to Check Battery Health and Performance Management Switch through iOS “.
