Turn Notch Into a Battery Indicator?

Yes, you can turn the notch on your phone into a battery indicator, but it requires a third-party app and only works on certain Android devices. This article explains which apps can do it, how to set them up, and what limitations you’ll face on iPhones.

What the Notch Is For

The notch is the cutout at the top of a phone screen that houses the front camera and Face ID sensors. Apple introduced it with the iPhone X in 2017, and many Android manufacturers followed with their own versions. The notch itself is just a physical housing for hardware — it doesn’t display anything by default. The screen area around it is where the status bar shows time, battery, and notifications.

Because the notch takes up space, some developers saw an opportunity to use that dead zone for extra info. On Android, apps like Energy Bar and Notch Battery can draw a thin colored bar around the notch that fills or empties based on battery level. On iOS, Apple doesn’t allow apps to draw on the notch area, so the only built-in option is the standard battery icon in the status bar.

How the Apps Work

These battery-notch apps use Android’s overlay permission to draw on top of other apps. They read the battery level from the system and then paint a colored line or arc around the notch cutout. The color can change as the battery drops — for example, green above 50%, yellow between 20-50%, and red below 20%.

Some apps also let you set the bar to pulse or blink when the battery is low. The overlay is always visible, even when you’re in full-screen apps or games, because it’s drawn at the system level. The apps are lightweight and don’t use much battery themselves, but they do require the overlay permission to be granted in Settings.

Here’s a typical setup on Android:

Install a notch battery app from the Google Play Store (e.g., Energy Bar or Notch Battery).
Open the app and grant the “Display over other apps” permission when prompted.
Choose the notch style — some apps detect the notch shape automatically, others let you pick from a list.
Set the color thresholds and bar thickness.
Enable the overlay and test it by locking and unlocking your phone.

If the app doesn’t detect your notch correctly, you can manually adjust the bar’s position and size in the app’s settings.

iPhone Limitations

On iPhones, you cannot turn the notch into a battery indicator because iOS doesn’t allow apps to draw over the system status bar or the notch area. Apple’s design guidelines prohibit any app from covering the status bar, and the notch is part of that protected zone. While there are jailbreak tweaks that can do it, those require modifying iOS and are not available on standard iPhones.

The closest you can get on an iPhone is to enable the battery percentage in the status bar. Go to Settings > Battery and toggle on “Battery Percentage.” This shows the numeric percentage inside the battery icon, but it doesn’t use the notch itself. For a more visual indicator, you can add a battery widget to your home screen, but again, it’s not on the notch.

How to Choose the Right App

If you’re on Android, the choice of app comes down to features and compatibility. Here are some factors to consider:

Notch detection: Some apps automatically detect the notch shape and position; others require manual adjustment.
Customization: Look for apps that let you change colors, thickness, and animation.
Battery drain: Check reviews to see if the app is known to be battery-hungry.
Ads: Many free apps show ads; paid versions usually remove them.
Compatibility: Make sure the app supports your Android version (most require Android 8.0 or higher).

It’s also worth checking if the app has a “low battery” warning feature that flashes the bar when the battery is critically low. Some apps even add a charging animation when you plug in.

Common Problems and Fixes

Users often report a few issues with notch battery apps:

Bar doesn’t show up: Usually because the overlay permission wasn’t granted. Go to Settings > Apps > [App] > Display over other apps and enable it.
Bar is in the wrong position: Adjust the X/Y offset in the app’s settings until it aligns with your notch.
Bar disappears after reboot: Some apps need to be restarted after a reboot. Check the app’s settings for a “start on boot” option.
Battery percentage is wrong: The app might be reading a different battery source. Try restarting the app or your phone.
App causes lag: Some overlays are poorly optimized. Try a different app or lower the refresh rate in the app’s settings.

If the app still doesn’t work, check if your phone’s manufacturer has a built-in battery indicator that uses the notch. Some devices, like older LG phones, had a feature called “Second Screen” that used the area next to the notch for notifications and battery info.

Privacy and Security Considerations

Granting overlay permission to any app carries some risk. A malicious app could use that permission to show fake alerts or trick you into tapping things you didn’t intend. Only install notch battery apps from reputable developers with good reviews, and avoid apps that request other permissions like contacts or location.

Also, note that these apps can’t access your battery hardware directly — they read the same battery level that the system reports. So there’s no risk of damaging your battery by using them. The only real downside is a tiny bit of extra battery drain from the overlay rendering, which is usually negligible.

Alternatives to Notch Battery Apps

If you don’t want to install a third-party app, there are other ways to see your battery level at a glance:

Battery percentage in the status bar: On Android, you can enable this in Settings > Battery > Battery percentage. On iPhone, it’s in Settings > Battery as described earlier.
Battery widgets: Both Android and iOS allow you to add a battery widget to your home screen that shows the percentage and sometimes a graph.
Always-on display: Many phones can show a small battery icon on the lock screen when the screen is off.
LED notification lights: Some Android phones have a small LED that blinks red when the battery is low.

These built-in options are generally more reliable and don’t require extra permissions.

Frequently Asked Questions

Does the notch battery app work on all Android phones?

No, it depends on the phone’s notch shape and the app’s compatibility. Most apps work on phones with a centered punch-hole or a wide notch, but some may not support teardrop or corner cutouts. Check the app’s description or reviews for your specific model.

Will this void my warranty?

No, installing a battery indicator app is just like installing any other app. It doesn’t modify the system or hardware, so it won’t void your warranty. On iPhones, jailbreaking would void the warranty, but using the built-in battery percentage won’t.

Can I use the notch to show other things, like notifications?

Yes, some Android apps like NotchBar can display notifications, time, or even a music visualizer around the notch. The same overlay technique is used, but the app draws different content.

Is there a way to turn the notch off entirely?

On some Android phones, you can hide the notch by going to Settings > Display > Full screen apps and choosing “Hide notch” or similar. This makes the screen area around the notch black, effectively making it invisible, but it doesn’t repurpose the notch itself.

Why does my iPhone not have this feature?

Apple restricts apps from drawing over the status bar and the notch area for design consistency and security. The only way to get a notch battery indicator on an iPhone is to jailbreak it, which is not recommended for most users.
