When the battery icon on your iPhone turns yellow, it signifies that Low Power Mode has been enabled. This feature is aimed at extending your device’s battery life when you’re not able to charge it immediately. Low Power Mode manages your iPhone’s resources more conservatively by reducing background activity, automatic downloads, and some visual effects.
Why Is My Battery Yellow?
Activating Low Power Mode is straightforward. You might turn it on manually when anticipating a long day away from a charger, or your iPhone may automatically prompt you to enable it when the battery level drops to a certain percentage. Deactivating it is just as easy through the battery settings once you no longer need the conservation measures or if you have sufficiently charged your device.
Understanding Battery Status Indicators
Your iPhone can display the battery status in several ways to keep you informed about its current charge level and power-saving state.
iPhone Battery Yellow Signal
When your iPhone battery icon is yellow, this signals that your device is in Low Power Mode. This mode is automatically activated when your battery level goes below 20%, or you can enable it manually. It serves to extend battery life by reducing background activity and automatic downloads. You can deactivate Low Power Mode through your iPhone’s settings.
Battery Saver Mode Explained
Battery Saver Mode is similar to Low Power Mode on iOS but refers to Android and other operating systems. When activated:
- It limits device performance
- Decreases screen brightness
- Decreases the frequency of app updates
Understanding these modes helps you manage your phone’s power effectively and ensures you aren’t caught off-guard by your device’s power-saving features.
Activating and Deactivating Low Power Mode
When your iPhone’s battery turns yellow, it indicates that Low Power Mode is on. This feature helps extend your device’s battery life by reducing power consumption.
How to Enable Low Power Mode
- Open Settings: Navigate to the Settings app on your iPhone.
- Access Battery Settings: Scroll down and tap on ‘Battery’.
- Activate Low Power Mode: Switch the toggle next to Low Power Mode to the on position.
Turning Off Low Power Mode Manually
- Go to Settings: Start by opening the Settings app.

- Deactivate Low Power Mode: Tap the toggle next to Low Power Mode, turning it off.
Automatic Deactivation of Low Power Mode
Low Power Mode will automatically turn off when your iPhone’s battery reaches a certain charge level, typically around 80%. This happens without any manual intervention, ensuring your device returns to its normal power settings once sufficiently charged.
Implications of Using Low Power Mode
When your iPhone’s battery turns yellow, it signifies that Low Power Mode is active. This feature extends battery life, but it also has a direct influence on how your device operates and interacts with apps.
Effects on Smartphone Performance
- Processor Speed: The performance of your device’s central processor is reduced to conserve energy, which can result in slower app performance and reduced visual effects.
- Network Connectivity: Background tasks such as email fetching and automatic downloads are paused or reduced to minimize power usage.
Impact on App Functionality
- App Refresh Rate: Apps may stop refreshing in the background, which can delay notifications or updates unless opened directly.
- Location Services: GPS functionality in some apps may be limited, affecting navigation or location tracking until Low Power Mode is disabled.
To manage Low Power Mode, you can navigate to your Settings > Battery or customize controls in the Control Center on your device.
