The iPhone does not include a setting that lets you choose an arbitrary color for the battery icon. You cannot open Settings and make the normal battery indicator blue, purple, pink, or another custom color.
The battery icon can change appearance automatically because iOS uses its color and symbols to communicate battery and charging status. For example, Apple uses a yellow battery icon when Low Power Mode is active.
Why the iPhone Battery Icon Changes Color
The color is controlled by iOS rather than by a color picker. Its appearance can change according to the phone’s current state and the surrounding interface.
If your battery icon suddenly looks different, that usually does not mean anything is wrong with the battery.
How to Make the Battery Icon Yellow
If you specifically want the yellow battery icon, turn on Low Power Mode.
- Open Settings.
- Tap Battery.
- Turn on Low Power Mode.
The battery indicator becomes yellow while Low Power Mode is active. Low Power Mode also reduces some background activity and other power-consuming features, so it should not be treated as a purely cosmetic color setting.
Can You Make the Battery Icon Green?
You may see charging-related changes in the battery indicator while the iPhone is connected to power, but there is no permanent “green battery icon” preference that you can select for normal use.
Can You Pick a Custom Battery Color?
Not with standard iOS settings. Themes, wallpapers, widgets, and Home Screen customization can change much of the way an iPhone looks, but they do not provide a supported system setting for choosing the status-bar battery icon color.
Be cautious with instructions that claim you must install an unknown configuration profile, jailbreak the phone, or grant unusual permissions just to recolor the battery indicator. Those changes are unnecessary for normal iPhone use and can create security, stability, or update problems.
Show the Battery Percentage Instead
If your real goal is to make the battery level easier to understand, displaying the percentage is more useful than changing its color.
- Open Settings.
- Tap Battery.
- Turn on Battery Percentage if the option is available on your model.
You can also check the Batteries widget for a larger view of the iPhone battery level and, when supported, connected accessories.
What a Yellow Battery Icon Means
A yellow battery icon means Low Power Mode is on. This mode can reduce background activity, automatic downloads, visual effects, and other features to help the battery last longer.
Low Power Mode can turn off automatically after the battery has charged sufficiently, so do not be surprised if the icon later returns to its normal appearance.
What to Do if the Battery Icon Looks Wrong
If the icon seems stuck or the battery percentage is behaving strangely, try these basic checks:
- Open Settings and verify whether Low Power Mode is on.
- Connect or disconnect the charger and check whether the status changes.
- Restart the iPhone.
- Install any available iOS update.
- Check Settings > Battery for battery usage and health information if you are also experiencing unusually short battery life.
Summary
You cannot freely choose the iPhone battery icon color in iOS. The system changes the indicator to communicate status; a yellow icon, for example, indicates Low Power Mode. If you want clearer battery information, enable Battery Percentage or use the Batteries widget rather than installing software that promises unsupported color customization.
