How to Check Your iPhone Battery Health with CoconutBattery
Updated guideDocumentation reviewed .
Current guidance
Start with Apple’s built-in Battery Health information and its model-specific battery guidance. Cycle count is useful context, not a universal replacement deadline: Apple’s design-cycle expectations differ by iPhone generation. coconutBattery can provide additional Mac/iOS battery information, but a third-party reading alone does not diagnose a faulty battery. If the phone reports a service problem, loses power unexpectedly or has physical damage, use Apple’s service guidance.

When Does My Battery Need a Replacement?
Once you scan your phone using CoconutBattery you’ll be given a lot of information about your phone.
The main numbers to look at are Design Capacity and Cycle Count.
If your Design Capacity is in the low 80’s you’ll see degraded performance and most likely need a battery replacement. Additionally it’s recommended to get a replacement after 500+ cycles.
Think of your phone’s battery like tires on a car, the car will still drive with worn down tires but performance will suffer. No phone’s battery is designed to last indefinitely.
Additionally if you’d like to see an example of an iPhone with good battery health it’ll be listed with 100% design capacity.
Also we will note you can start a chat on the Apple Support app about your phone’s battery and Apple can check your battery health remotely.
