Turn on Battery Percentage in Settings
To display the battery percentage next to the battery icon in your status bar, open Settings and tap Battery. Then tap Battery Health & Charging. Toggle Battery Percentage to the on position (it will turn green). Close Settings and look at the top right of your screen — you should now see a number like "87%" next to the battery icon.
This setting works on iPhone XS and newer models. If you have an older iPhone with a home button, the battery percentage appears in the status bar at the top but may look slightly different depending on your model.
Key Takeaways
- Battery percentage is turned on through Settings > Battery > Battery Health & Charging > Battery Percentage.
- Once enabled, the percentage appears in the top right corner of your screen next to the battery icon.
- You can also see your battery percentage by swiping down from the top right to open Control Center on newer iPhones.
- If the toggle is already on but you do not see the percentage, restart your iPhone to refresh the display.
Where to Find Battery Percentage Without Changing Settings
If you do not want to turn on the permanent display, you can check your battery percentage at any time by swiping down from the top right corner of your screen to open Control Center. The battery percentage appears at the top of the Control Center panel, above the brightness and volume sliders.
This method works on iPhone X and newer. On older iPhones with a home button, swipe up from the bottom of the screen instead to open Control Center.
Why Your Battery Percentage Might Not Show
If you turned on the Battery Percentage toggle but still do not see the number on your screen, the most common reason is that your iPhone needs a restart. Hold down the side button and either volume button, then slide to power off. Wait a few seconds, then press the side button again to turn it back on.
Another reason the percentage may not display is if your status bar is too crowded with other icons — on some iPhones, the system hides the percentage to make room for signal, Wi-Fi, and other indicators. If this happens, close some background apps or disable features like location services temporarily to free up space.
Battery Percentage on Older iPhone Models
If you own an iPhone 6, 7, 8, or another model with a home button, the battery percentage setting is in a slightly different location. Open Settings, tap Battery, then toggle Battery Percentage on. The percentage will appear in the status bar at the top of your screen, though the layout may differ from newer models.
On these older models, the battery icon itself is larger and the percentage sits inside or next to it. The setting works the same way — once you toggle it on, it stays on until you turn it off again.
Using Low Power Mode to Monitor Battery Faster
If you want to see your battery status more prominently, you can enable Low Power Mode through Control Center. When Low Power Mode is on, your status bar turns yellow and your iPhone slows down slightly to extend battery life. This is useful when your battery is below 20% and you want a visual reminder that you are running low.
To turn on Low Power Mode, open Control Center and tap the battery icon. Your screen will show the current percentage and the mode will set up. You can also set Low Power Mode to turn on automatically at 20% battery by going to Settings > Battery > Battery Health & Charging and toggling on Low Power Mode under the Charging section.
Checking Battery Health Alongside Percentage
While you are in the Battery settings, you can also see your Battery Health information. This shows the maximum capacity of your battery as a percentage — for example, "82% Maximum Capacity" means your battery can hold 82% of the charge it could when new. This number naturally decreases over time as you charge and use your phone.
If your maximum capacity drops below 80%, your iPhone may feel slower during heavy use. If it drops below 50%, Apple recommends considering a battery replacement. You can see this information in Settings > Battery > Battery Health & Charging.
Frequently Asked Questions
Why does my iPhone show battery percentage in Control Center but not on the status bar?
Your Battery Percentage toggle may be off, or your status bar may be too crowded with other icons. Go to Settings > Battery > Battery Health & Charging and make sure Battery Percentage is toggled on. If it is already on, restart your iPhone. If the percentage still does not appear, try disabling location services or closing background apps to free up space in the status bar.
Can I see battery percentage on my lock screen?
On iPhone 12 and newer, you can add a battery widget to your lock screen to see the percentage at a glance. Long-press your lock screen, tap the plus button, search for "Battery," and add the battery widget. This shows your iPhone battery and any connected device batteries like AirPods or Apple Watch.
Does showing battery percentage drain my battery faster?
No. Displaying the battery percentage uses a negligible amount of power and has no noticeable effect on how long your battery lasts. It is purely a display setting and does not change how your iPhone manages power.
What is the difference between battery percentage and battery health?
Battery percentage is how much charge your battery currently holds — for example, 75% means your battery is three-quarters full. Battery health is the maximum capacity your battery can hold compared to when it was new. A phone at 100% charge with 80% health still has a full charge, but that full charge is 80% of what it was originally.
