If you’ve ever noticed your iPhone’s battery symbol turning yellow even when it’s fully charged, you might be wondering why this happens and if it means there’s a problem with your device. This post will look at the common problem of a yellow battery at 100% charge and offer practical ways to ensure your iPhone runs smoothly.
What is Low Power Mode?
The activation of “Low Power Mode” on your iPhone is closely related to the yellow battery issue at 100% charge. When your battery level falls below 20%, your iPhone will prompt you to use Low Power Mode to save battery life. If you do not activate it now, the phone will remind you when the battery level hits 10%. Failing to turn on Low Power Mode during these warnings results in the battery icon turning red, indicating a critically low battery level.
Common Cause of the Yellow Battery at 100% Charge
Sometimes, Low-Power Mode may be accidentally activated, resulting in the yellow battery indication even when the battery is fully charged. Understanding these causes can assist you in preventing the problem from recurring.
Impact of Low Power Mode on iPhone Performance
While Low Power Mode effectively extends battery life, there are some drawbacks. Certain features and background operations are disabled to save power, which has an impact on app performance and functionality. It is critical to strike a balance between preserving battery life and keeping device functionality.
Resolving the Yellow Battery Issue
To resolve the yellow battery issue with 100% charge, manually off Low Power Mode. We’ll walk you through the process, ensuring that your battery indicator displays accurately.
Battery Health Check
Apple launched the Battery Health feature on some iPhone models. We’ll show you how to utilize this function to analyze the health of your battery and determine whether it needs to be replaced.
How to Remove iPhone from Low-Power Mode
- Unlock Your iPhone: Begin by unlocking your iPhone with your passcode, Face ID, or Touch ID to gain access to the Settings app and off Low Power Mode.
- Access the Control Center: To open the Control Center, slide down from the top right corner of your screen (on iPhone models with Face ID) or up from the bottom of your screen (on iPhone models with a home button).
- Check Low Power Mode Icon: The Low Power Mode icon, which resembles a battery, can be found in the Control Center. If it’s highlighted in yellow, that signifies Low Power Mode is on. Low Power Mode is already turned off if the icon is not highlighted.
- Confirm Battery Percentage: Check the battery % in the top right corner of the screen to ensure that Low Power Mode is turned off. It should now show the standard battery icon, and the percentage should represent the correct charge level.
Other Battery Warning Colors to Look out for on iPhone

- Low Battery Alert: When your battery level falls below 20%, your iPhone will display a pop-up alert recommending that you select Low Power Mode to save battery life. If you ignore this warning, it will appear again when the battery level hits 10%.
- Low Power Mode Indicator: The battery symbol glows yellow when Low Power Mode is active. This means that certain features and functionalities are temporarily disabled to preserve power.
- Battery Health Warnings: On iPhones running iOS 11.3 and later, the “Battery Health” function is available in Settings. If your battery health is significantly degraded, you may see a warning message suggesting you consider replacing the battery.
- Charging Warnings: Occasionally, when you connect your iPhone to a charger, you might see a warning message if the charger is not recognized or not genuine. This serves as a safety precaution to prevent potential issues with charging.
