Understanding the Premature Shutdown Problem

Why Is My iPhone Shutting Off With Battery Left?

1. Battery Degradation: Lithium-ion batteries naturally degrade over time and charge cycles. Their capacity diminishes, meaning the "100%" you see represents less actual energy storage. More critically, a degraded battery struggles to deliver the peak power bursts required during demanding tasks (like launching an app, using the camera, or in cold weather), causing voltage drops that trigger an emergency shutdown to protect the device.

2. Inaccurate Battery Calibration: The software estimating your battery percentage can become miscalibrated, especially after partial charges or software updates. It thinks there's more charge left than the physical battery can actually provide under load.

3. Extreme Temperatures: Both excessive heat and cold significantly impact battery chemistry, reducing its ability to deliver power effectively when needed.

4. Software Issues: Occasionally, bugs within the device's operating system can cause incorrect power management.
