You cannot change the actual color of an iPhone battery

Apple does not make the battery itself a user-changeable color. The battery inside your iPhone is a sealed lithium-ion cell in a standard silver or metallic finish, and you cannot paint it, dye it, or swap it for a different color without replacing the entire battery — which requires opening the phone and voiding your warranty.

What you can change is how the battery appears on your screen. The battery icon in the status bar (top right on most iPhones) can display in different colors depending on your settings and device condition. You can also customize how battery information shows up in Control Center and on your lock screen.

Key Takeaways

  • The physical battery inside your iPhone cannot be changed to a different color without professional replacement, which voids your warranty.
  • The battery icon in your status bar changes color automatically based on your device's charge level and Low Power Mode status.
  • You can customize the appearance of battery percentage and status in Settings under Battery, Display & Brightness, and Control Center.
  • Third-party apps cannot change your actual battery color, but some allow you to customize how battery information displays on your lock screen.

How the battery icon color changes automatically

Your iPhone's battery icon shifts color based on what is happening with your device. When your battery is above 20 percent, the icon appears in black or white (depending on your Light or Dark mode). Once your battery drops below 20 percent, the icon turns red to warn you that you are running low on charge.

If you turn on Low Power Mode, the battery icon turns yellow or amber. This happens automatically when you enable Low Power Mode in Settings or Control Center, and it signals that your phone is restricting background activity to extend battery life. The color reverts to black or white once you turn Low Power Mode off or charge your phone above 80 percent.

Customizing battery display in Settings

You can control whether the battery percentage appears next to the icon. Go to Settings > Battery > Battery Percentage and toggle it on. This shows the exact number (like 87%) alongside the icon in your status bar.

For more detailed battery information, open Settings > Display & Brightness and look for battery-related options. Some iPhone models let you choose whether battery percentage displays in the status bar or only in Control Center. You can also enable Low Power Mode from the Battery settings, which changes the icon color to yellow and adjusts your phone's performance.

Using Control Center to view battery details

Control Center shows a larger, more detailed view of your battery status. Swipe down from the top-right corner of your screen (or up from the bottom on older iPhones) to open Control Center, and you will see your current battery percentage displayed prominently.

You can customize what appears in Control Center by going to Settings > Control Center and selecting which battery-related controls to include. This does not change the battery color itself, but it lets you decide how much battery information you see and where.

Lock screen battery widget options

On iPhone 14 and newer models, you can add a battery widget to your lock screen that displays your iPhone's charge level alongside other device batteries (like AirPods or Apple Watch). Long-press your lock screen, tap Customize, and add the Battery widget from the available options.

This widget displays battery percentages in a list format and uses the same color system as your status bar — black or white for normal charge, red for low battery, and yellow for Low Power Mode. The widget itself cannot be recolored, but it provides a quick visual reference without opening Control Center.

What third-party apps cannot do

Apps from the App Store cannot change your iPhone's actual battery color or the color of the system battery icon in your status bar. Apple restricts access to system-level features like the status bar icon, so any app claiming to change your battery color is either misleading or only changing how battery information appears within that app alone.

Some apps offer custom lock screen designs or widgets that display battery information in different colors, but these are separate from your phone's real battery display. If an app asks for unusual permissions or claims it can change your system battery icon, it is not doing what it says.

When you might need to replace your actual battery

If your battery is draining unusually fast, not holding a charge, or swelling (which you would notice as your phone feeling warm or the back bulging slightly), you may need a replacement. Apple offers battery replacement through the Apple Store or authorized service providers. The cost varies by iPhone model, but it is typically between $50 and $100.

Third-party repair shops can also replace batteries, often at a lower cost, but using non-Apple parts may affect your phone's performance and voids any remaining warranty. If your iPhone is still under warranty or covered by AppleCare+, battery replacement may be covered at no cost if the battery has degraded below 80 percent capacity.

Frequently Asked Questions

Can I paint or wrap my iPhone battery to change its color?

No. Painting or wrapping the battery risks damaging it and creating a fire hazard. The battery must remain in direct contact with your phone's internal cooling system. Any modification voids your warranty and can harm your device.

Why is my battery icon red?

Your battery is below 20 percent charge. Plug in your phone to charge it. The icon will turn black or white once you reach 20 percent or higher. If your battery drains to red very quickly, your battery may be degraded and need replacement.

Does Low Power Mode permanently change my battery color?

No. Low Power Mode turns your battery icon yellow or amber only while it is active. Once you disable Low Power Mode or charge your phone above 80 percent, the icon returns to black or white. The setting does not affect your actual battery.

Can I change the battery icon color in Dark Mode?

The battery icon color is determined by your charge level and Low Power Mode status, not by Dark Mode. In Dark Mode, the icon appears white instead of black, but the red and yellow warning colors remain the same.

What does it mean if my battery icon is yellow?

Yellow means Low Power Mode is on. Your iPhone is limiting background activity, reducing performance, and dimming the display to extend battery life. Turn it off in Settings or Control Center when you no longer need it.
