The quickest way to see your battery percentage

Your iPhone shows a battery icon in the top-right corner of the screen, but it does not display the exact percentage by default. To see the number alongside the icon, you need to turn on Battery Percentage in Settings. This takes about 30 seconds and works on iPhone XS and newer models.

Open Settings, tap Battery, then tap Battery Health & Charging. Toggle on Show Percentage. The number will appear next to the battery icon in your status bar when ready.

Key Takeaways

  • Battery percentage appears in the top-right status bar next to the battery icon once you enable it in Settings.
  • This feature is available on iPhone XS, iPhone XS Max, iPhone XR, and all newer iPhone models.
  • The toggle is found under Settings > Battery > Battery Health & Charging > Show Percentage.
  • Once enabled, the percentage displays on your lock screen, home screen, and throughout your phone.

Step-by-step instructions for iPhone XS through iPhone 15

Start on your home screen or lock screen. Swipe up from the bottom of the screen (or down from the top-right on newer models) to access Settings, or tap the Settings app directly.

Once Settings opens, scroll down and tap Battery. You will see options related to battery management. Tap Battery Health & Charging—this is the second option under Battery.

In Battery Health & Charging, look for the toggle labeled Show Percentage. It will be near the top of the screen. Tap the toggle to turn it on. The toggle will turn green, and you can now close Settings. The percentage will display in your status bar within seconds.

Where the percentage appears on your screen

Once enabled, the battery percentage shows in the top-right corner of your screen, right next to the battery icon. On the lock screen, it appears in the same location. The number updates in real time as you use your phone—if your battery drops from 87% to 86%, the display updates when ready.

The percentage is visible whether your phone is in Light Mode or Dark Mode. It remains visible even when you have notifications on the screen, though the icon may shift slightly depending on how many signal bars or other status indicators are active.

Why older iPhones cannot show battery percentage in the status bar

iPhone X and earlier models do not have the Show Percentage toggle in Settings. Apple did not include this feature in those devices, and it cannot be added through a software update. If you own an iPhone X, iPhone 8, iPhone 7, or an earlier model, you can still check your battery percentage by swiping down from the top-right corner to open Control Center and looking at the battery icon there.

Control Center displays a larger battery icon with the percentage inside it. This is the standard way to view the exact percentage on older iPhones, though it requires opening Control Center each time rather than seeing it constantly in the status bar.

Turning the percentage off if you prefer the icon alone

If you enable Show Percentage and later decide you prefer the cleaner look of just the battery icon, you can turn it off the same way you turned it on. Go to Settings > Battery > Battery Health & Charging and toggle off Show Percentage. The number will disappear from your status bar when ready.

Some people find the percentage helpful for deciding when to charge, while others prefer the simpler icon. There is no performance difference between having it on or off—it is purely a visual preference.

What the battery percentage tells you

The percentage represents how much charge your battery currently holds, from 0% to 100%. At 100%, your battery is fully charged. At 20%, you have one-fifth of your battery remaining. Most iPhones show a low battery warning around 20% and enter Low Power Mode at that point if you have it enabled.

The percentage does not tell you how long your phone will last—that depends on what you are doing. Watching video drains the battery faster than reading text, so two phones at 50% may have very different amounts of time remaining. The percentage is a snapshot of how much charge is stored, not a prediction of usage time.

Frequently Asked Questions

Why does my battery percentage disappear sometimes?

If you have Low Power Mode enabled, the percentage may appear in a different color (usually yellow or orange) but should still be visible. If it disappears entirely, check that Show Percentage is still toggled on in Settings > Battery > Battery Health & Charging. Restarting your phone can also fix display glitches.

Does showing the battery percentage drain my battery faster?

No. Displaying the percentage in the status bar uses negligible power. The battery drains at the same rate whether the percentage is shown or hidden. The feature has no impact on how long your phone lasts on a single charge.

Can I see the battery percentage on my Apple Watch?

Yes, but the method is different. On your Apple Watch, swipe down from the top of the screen to open Control Center, and the battery percentage appears there. You cannot display it constantly in the watch face status bar the way you can on iPhone.

What does it mean if the percentage is red?

A red battery icon or percentage means your phone is in Low Power Mode or has very low battery (usually below 20%). Red is a warning that you should charge your phone soon. Plug it in to restore normal operation and clear the red indicator.
