When the battery icon on an iPhone turns yellow, it indicates that Low Power Mode is active. This is a built-in feature that helps conserve battery life when it gets low. By reducing certain functions such as mail fetch, background app refresh, and some visual effects, Low Power Mode can help extend the iPhone’s battery life until the user can recharge the device.
Activating Low Power Mode is straightforward. A user needs to go to the Settings app, select Battery, and then toggle the switch for Low Power Mode. This simple action can be the difference between a phone dying in the middle of the day and making it through until nighttime.

Understanding iPhone’s Battery Icon Colors
The iPhone’s battery icon can show different colors such as yellow, green, red, and white. These colors tell you about the battery’s charge level and whether certain features are active.
The Meaning Behind the Yellow Battery Icon
When the iPhone battery icon turns yellow, it indicates Low Power Mode is on. This mode is an iPhone feature that helps extend battery life when the charge is low. It automatically activates when your battery level drops to 20% or manually through the Settings app. Low Power Mode reduces certain functions like mail fetch and background app refresh which can drain battery.
Distinguishing Between Colors: Green, Red, and White
The iPhone battery icon changes to green when it has a sufficient charge and is connected to a charger. Once it’s fully charged, the battery icon appears green in the status bar. A red battery icon means the iPhone’s battery is very low and needs charging immediately. When not charging or in Low Power Mode, the battery icon is white, which indicates a normal battery state. The color of the battery icon is a quick and easy way to check your iPhone’s battery status at a glance.
Managing iPhone Battery Health and Settings
Managing your iPhone’s battery is crucial for both daily performance and long-term device health. Proper settings can help extend battery lifespan and improve overall user experience.
How to Toggle Low Power Mode and its Effects
Low Power Mode on an iPhone preserves battery life when the battery reaches 20% or you choose to enable it manually. To toggle this mode:
- Open the Settings app.
- Scroll down to and tap Battery.
- Switch the Low Power Mode toggle to on or off.
When you activate Low Power Mode, the iPhone reduces background activity, lowers screen brightness, and adjusts system animations. This can extend battery life until you can recharge. The battery icon turns yellow to indicate Low Power Mode is active. Once the device charges above 80%, the mode will automatically turn off.
Adjusting Settings to Optimize Battery Lifespan
Prolonging your iPhone’s battery lifespan involves adjusting settings that impact battery consumption. Key areas to adjust include:
- Brightness: Set Auto-Brightness to adjust screen brightness automatically or manually lower it to save power.
- Battery Health: Monitor the Maximum Capacity metric in Settings > Battery > Battery Health to check your battery’s condition over time.
- Display Settings: Limit the Display Refresh Rate, if available, to reduce power usage.
By carefully managing these settings, you can minimize battery drain and maintain iPhone battery health over time, leading to a longer lifespan for your device.
Does Low Power Mode Charge Your iPhone Slower?
No, Low Power Mode does not directly charge your iPhone slower. It might even help your iPhone charge slightly faster in some cases.
Low Power Mode primarily focuses on reducing your iPhone’s energy consumption by limiting background activity, dimming the screen, and disabling certain features. When your iPhone is in Low Power Mode while charging, it uses less energy overall, potentially allowing more power to be directed towards charging the battery.
However, any difference in charging speed is likely to be negligible. The main benefit of Low Power Mode is to extend your battery life, not to accelerate charging. If you need to charge your iPhone quickly, it’s recommended to use a fast charger or connect it to a power outlet rather than relying on Low Power Mode.
