Troubleshooting iPhone 6s Battery Stuck and Sudden Drops

If your iPad battery percentage is stuck, it could be caused by a variety of issues, such as a battery calibration problem, a faulty battery, overheating, software glitches, power management settings, or a faulty charger or cable.

For the issue you're experiencing with your iPhone 6s battery, even with a reported battery health of 100, several factors could be contributing to this behavior. Here are some possible explanations and steps to help you address it:

Battery Calibration

Parts of the battery#39;s data can become inaccurate over time, causing the software to not reflect the actual charge level accurately. To recalibrate your battery, fully charge it to 100%, then use it until it completely discharges and charge it back to 100% without interruption.

Background Processes

Certain apps running in the background can drain the battery more than usual. Check your battery usage by going to Settings Battery to view which apps are using the most power and then optimize them to reduce power consumption.

Temperature Effects

Batteries can be sensitive to temperature changes. If your iPhone is exposed to extreme temperatures, it can affect battery performance and reporting. Keep it in a stable environment.

Software Glitches

Occasionally, iOS can have bugs that cause erratic battery behavior. Ensure your iPhone is running the latest version of iOS. If the issue persists, consider performing a reset or restoring the device.

Battery Aging

Even a battery reported as 100% healthy can show irregularities in how it holds a charge as it ages. Lithium-ion batteries can wear out over time, leading to unpredictable behavior.

Hardware Issues

If the battery has been replaced or there are issues with the internal components, it could lead to erratic behavior. In this case, taking your device to a professional for a checkup is recommended.

Suggested Steps for Troubleshooting

Calibrate the Battery: Fully charge and then fully discharge your iPhone to reset the calibration process. Check for Software Updates: Go to Settings General Software Update to ensure your iOS is up to date. Download and install any available updates. Monitor Battery Usage: In Settings Battery, look for any apps that are using more power than usual and restrict or remove them from automatic background execution, if possible. Reset Settings: As a last resort, reset all settings (Settings General Reset Reset All Settings) to see if it helps mitigate the issue.

If the problem persists after trying these steps, consulting with Apple Support or visiting an authorized service provider may be necessary to diagnose a potential hardware issue.
