Since the iOS 17.6 update, some iPhone 14 Pro users have noticed that their battery reaches 100% without the usual pause of optimized charging. This mechanism, designed to limit the wear of lithium-ion batteries, seemed temporarily disabled, raising concerns about the durability of the devices.
This situation illustrates how an update can change essential settings and why it is crucial to monitor the battery status after each installation.
Optimized charging interrupted on iPhone 14 Pro
Optimized charging delays reaching 100% based on the user’s charging habits. With iOS 17.6, some iPhone 14 Pros ignored this pause, resulting in an immediate full charge.
Result: the battery remained at full charge longer, which increases chemical wear and capacity loss in the long term. This anomaly did not affect all devices, but enough to cause numerous reports on Apple forums and Reddit.
How did users detect the problem?
The reports detailed several recurring behaviors:
- Disappearance of the “Optimized charging enabled” mention in settings
- Charge reaching 100% immediately, even during usual nighttime use
- Temporary resolution after restarting or manually reactivating the function
These observations confirmed that it was a software bug related to iOS 17.6, specific to certain iPhone 14 Pros.
Why does iOS 17.6 temporarily block optimized charging?
The bug comes from a calibration malfunction of the battery management software. The system did not correctly update the routines for learning charging habits, temporarily disabling the automatic pause.
Experts explain that this type of conflict is common during updates, especially on recent devices where previous calibration data interferes with new software optimizations.
Temporary solutions to reactivate optimized charging
Affected users can restore normal operation by:
- Restarting the iPhone, which restarts the system services
- Disabling and then re-enabling optimized charging in the Battery settings
- Checking for subsequent iOS updates, which often include quick fixes
These interventions help limit the impact on the battery before an official fix.

The risks if the function remains inactive
If optimized charging does not activate:
- The battery remains at 100% longer, increasing chemical wear
- The generated heat can slightly accelerate cell aging
- Full charge cycles become more frequent, reducing maximum capacity over several months
Even if the effects are gradual, they show the importance of monitoring the battery after an update.
