Step 1 | How to Check Your iPhone's Battery Health
- Confirm that your device's operating system is iOS version 11.3 or a subsequent release.
- Launch the Settings application.
Step 2
- Navigate within the Settings application by moving through the list until you locate and choose the "Battery" option.The "Battery" setting is accessible by using a scrolling motion to find it within the Settings app.To access battery-related configurations, utilize the Settings app and find the "Battery" entry through scrolling.
Step 3
- Select the 'Battery Health' option by a brief touch.This action will display information regarding the condition of the battery.The presented data includes metrics such as maximum capacity and current health status.
Step 4
The Maximum Capacity value indicates the current charge capacity of your battery relative to its original factory specifications, which naturally diminishes with usage over time.Despite this reduction, your iPhone will continue to function; however, you may observe a decrease in overall battery longevity.Apple advises battery replacement when the Maximum Capacity falls to, or below, a level of 80%.
Step 5
The battery's ability to sustain the power demands of your iPhone is assessed by the Peak Performance Capability indicator.A standard result suggests the battery is functioning without limitations.If a potential system shutdown is noted, it signifies the battery's inability to deliver power rapidly enough, leading to an automatic shutdown.To avoid further unexpected power losses, your iPhone may reduce its operational speed.Manual control over peak performance is possible through disabling performance management; however, this setting becomes irreversible.You will receive a notification when the battery's health declines substantially, typically when its capacity drops below 80%, and this guide details the battery replacement procedure for the iPhone X, while alternative models can be found at the provided link.
