Have you ever glanced at your iPhone and noticed that your battery icon has turned yellow? This change in color can be unexpected and might leave you wondering what it signifies. You’re not alone! Many iPhone users encounter this and are curious about why their battery indicator suddenly shifts from the usual white, green, or red to yellow. The good news is that a yellow battery icon is not a cause for alarm, but rather a helpful indicator of a specific feature in action.
The yellow battery icon on your iPhone is a visual cue that Low Power Mode is currently enabled. This mode is a built-in feature designed to extend your iPhone’s battery life when it’s running low. When Low Power Mode is activated, either manually by you or automatically when your battery level dips to 20%, your iPhone makes several adjustments to conserve power.
Understanding Low Power Mode on Your iPhone
Low Power Mode is a smart and effective way to maximize the remaining battery charge on your iPhone. It temporarily reduces background activity and non-essential features to minimize battery consumption. Here’s a breakdown of what Low Power Mode typically affects:
- 5G (in some iPhone models): On iPhone 12 and later models, 5G connectivity might be limited to save power, except for video streaming. In most cases, your phone will switch to faster 4G LTE speeds which are still perfectly adequate for most tasks and less battery intensive.
- Auto-Lock Duration: The time it takes for your iPhone screen to automatically lock is shortened to 30 seconds to reduce display power usage.
- Display Brightness: Screen brightness is slightly reduced. You can still manually increase it, but the default is lower in Low Power Mode.
- Display Refresh Rate (on ProMotion iPhones): On iPhone models with ProMotion displays (like iPhone 13 Pro and later Pro models), the refresh rate is limited to 60Hz, making animations and scrolling slightly less smooth but saving battery.
- Visual Effects: Some non-essential visual effects and animations are reduced or disabled.
- iCloud Photos: iCloud Photos syncing might be temporarily paused, meaning new photos might not immediately upload to iCloud until Low Power Mode is turned off or your phone is charging.
- Automatic Downloads: App Store automatic downloads are disabled to prevent background processes.
- Email Fetch: Your iPhone will fetch new emails less frequently, meaning you might not receive instant email notifications.
- Background App Refresh: Apps running in the background will not refresh as often, limiting their data and battery usage.

How to Turn Off Low Power Mode and Revert to a Green Battery Icon
Once you understand that the yellow battery icon signifies Low Power Mode, turning it off and reverting your battery icon to its normal color (green when charging, white/black otherwise) is simple. Here’s how:
- Open Settings App: Locate and tap the “Settings” app icon on your iPhone Home Screen.
- Scroll Down to Battery: In the Settings menu, scroll down and tap on “Battery.”
- Toggle Off Low Power Mode: You will see a “Low Power Mode” toggle switch at the top of the Battery settings. If it’s green, it’s on. Tap the switch to turn it off. The toggle will turn gray, and your battery icon in the status bar will immediately change from yellow back to its regular color.
Alternatively, you can also turn off Low Power Mode from the Control Center:
- Open Control Center: Swipe down from the top-right corner of your iPhone screen (on iPhones with Face ID) or swipe up from the bottom of the screen (on iPhones with a Home button).
- Find the Battery Icon: Look for the Battery icon in the Control Center. If Low Power Mode is on, it will be yellow.
- Tap the Battery Icon: Tap the yellow battery icon to toggle Low Power Mode off. The icon will turn gray, and Low Power Mode will be deactivated.
After turning off Low Power Mode, your iPhone will resume its normal functions, and the battery icon will reflect the standard color scheme.
When Should You Use Low Power Mode?
While the yellow battery icon might initially seem unusual, Low Power Mode is a valuable tool to have at your disposal. It’s particularly useful in situations where you anticipate being away from a power source for an extended period and need to conserve battery life. For example:
- Traveling: When you are traveling, especially if you are unsure when you’ll be able to charge your iPhone next.
- Long Days Out: On days when you are out and about and using your iPhone heavily for navigation, photography, or communication.
- During Emergencies: In emergency situations where power outlets might be inaccessible and you need to ensure your phone stays on for as long as possible.
- Extending Battery Before Charging: Simply when you want to squeeze as much life as possible out of your remaining battery percentage before you can get to a charger.
In conclusion, seeing a yellow battery icon on your iPhone is simply an indication that Low Power Mode is active. It’s a helpful feature designed to extend your battery life when needed. Understanding what it means and how to control it allows you to effectively manage your iPhone’s power consumption and ensure you stay connected for longer.
