Understanding Your iPhone Battery Health: When 100% isn’t Always 100%
Have you ever noticed that your new iPhone battery health is at 100%, yet your phone still shows a 'Battery Calibration' message? This can be confusing and might leave you wondering why the battery is still under service even when it reports a perfect health score. In this article, we will explore possible reasons for this discrepancy and offer solutions to resolve the issue.
Why the Battery Health is 100% but It Still Shows Service
The first step in troubleshooting this issue is to understand that the battery health and the battery service status are two separate aspects of your iPhone's battery management system.
1. Battery Calibration
Sometimes, the battery management system needs to recalibrate. This can happen if the battery was not properly calibrated during the manufacturing process. It's a natural process that ensures the accuracy of the battery's status report.
2. Software Issues
A software glitch could also be causing the incorrect status. Ensure your iPhone is running the latest version of iOS, as updates often include bug fixes that could resolve these issues. You can check for updates by going to Settings General Software Update.
3. Hardware Issues
There might be a hardware issue with the battery or the device itself. Even if the battery health is fine, there could be a problem with the battery connection or other components. If you recently had the battery replaced or your phone was refurbished, this could be a potential cause.
4. Battery Replacement
If your phone was refurbished or if the battery was replaced, the new battery might not be recognized properly by the system. This can lead to the device showing service status despite a healthy battery reported by the health meter.
5. Diagnostics Needed
Performing a deeper diagnostic test might be necessary to determine the health of the battery or related components. You can initiate a battery test by going to Settings Battery Battery Health Perform Battery Stress Test. This will help you understand the overall health of your battery and identify any issues.
What to Do if the Issue Persists
If the problem persists, it might be best to contact Apple Support or visit an Apple Store for further assistance. They can provide expert advice and, if necessary, repair your device.

Why Does My iPhone Battery Show Service but Battery Health is 92?
It's important to note that the two metrics are not directly related. As batteries age and are used, their efficiency naturally decreases, but this does not necessarily mean the phone needs service. The battery health is a measure of the battery's remaining capacity, while the service status is a broader indicator of whether the battery needs repair or replacement.
You can check your battery health by going to Settings Battery Battery Health. The charging next to Maximum Capacity is your battery health metric.
Depending on when you bought the device, the battery health might have been tampered with by the previous owner to make it appear better than it is. If you're unsure about the battery health, perform the battery test mentioned above to get an accurate reading.
Lastly, it's worth noting that Apple's battery health system arbitrarily starts at 100%, which can make it seem confusing. However, a healthy battery will always show a high percentage, whether it's 92% or 100%. The important measure is the battery health (maximum capacity).
In conclusion, if your new iPhone battery health is at 100% but it still shows a Battery Calibration status, you have several options to resolve the issue. Check the battery calibration, software updates, perform a hardware diagnostic test, and contact Apple Support for professional assistance if needed.
