Turn on the battery percentage display in Settings
The battery percentage appears as a number next to the battery icon in the top-right corner of your iPhone screen. To turn it on, open Settings and tap Battery, then toggle Battery Percentage to the on position (it will turn green). The percentage will show when ready in your status bar.
This setting works on iPhone XS, iPhone XS Max, iPhone XR, and all newer models. If you have an iPhone X or earlier, the battery percentage toggle does not exist in Settings — those phones use a different display method that shows the battery icon only, without a number.
Once you turn it on, the percentage stays visible whenever your phone is unlocked. You can turn it off the same way by returning to Settings > Battery and toggling the switch to off.
Key Takeaways
- Open Settings, tap Battery, and toggle Battery Percentage on to see the number next to your battery icon in the top-right corner.
- This feature is available only on iPhone XS, XS Max, XR, and newer models — older iPhones do not have this option in Settings.
- The percentage displays whenever your phone is unlocked and updates in real time as your battery drains.
- You can turn the percentage off at any time by returning to the same toggle and switching it back to off.
What the battery percentage shows you
The number tells you exactly how much charge remains in your battery, from 0 to 100 percent. This is more precise than the battery icon alone, which changes color and shape as it drains but does not show the exact amount.
The percentage updates every time your battery level changes by 1 percent. If you are using power-hungry apps or features like video recording or GPS navigation, you may see the number drop noticeably every few seconds. In lighter use, it may stay the same for several minutes.
Why you might want the percentage visible
Seeing the exact number helps you decide when to charge. Some people charge when they hit 20 percent; others wait until 10 percent or lower. Without the percentage, you have to guess based on the icon shape and color alone.
The percentage is also useful if you are troubleshooting battery drain. If your phone is losing 5 percent per hour during normal use, you can spot that pattern more easily with the number visible. If it is draining much faster than usual, the percentage helps you notice the problem before your phone dies unexpectedly.
Battery percentage on older iPhones
iPhone X and earlier models do not have a battery percentage toggle in Settings. These phones show only the battery icon, which fills or empties as your charge changes. To see the exact percentage on these phones, swipe down from the top-right corner to open Control Center — the battery percentage appears there.
If you own an iPhone 8 or earlier, swipe up from the bottom of the screen instead to open Control Center. The battery percentage will display in the top-right corner of that panel.
The battery icon still appears with the percentage on
Turning on the battery percentage does not hide the battery icon. Both appear together in the status bar — the icon on the left and the number on the right. The icon still changes color (green when charging, red when low) and shape (filling as you charge) even with the percentage visible.
If your status bar looks crowded with both the icon and the number, you can turn the percentage back off. The icon alone takes up less space and still gives you a visual sense of your remaining charge.
Low Power Mode and the battery percentage
When you turn on Low Power Mode, the battery icon turns yellow or orange, and the percentage continues to display normally. Low Power Mode slows down your phone's performance and limits background activity to extend battery life — it does not change how the percentage appears or how often it updates.
You can turn on Low Power Mode from Control Center (swipe down from the top-right on newer iPhones, or swipe up from the bottom on older ones) or from Settings > Battery > Low Power Mode. The battery percentage will keep showing while Low Power Mode is active.
Frequently Asked Questions
Why is my battery percentage grayed out or not clickable in Settings?
Your iPhone model may not support this feature. Battery percentage as a toggle exists only on iPhone XS, XS Max, XR, and newer. If you have an iPhone X or earlier, the toggle will not appear in Settings at all. Check your phone model in Settings > General > About to confirm which version you own.
Does showing the battery percentage drain my battery faster?
No. Displaying the number in the status bar uses negligible power. The percentage is calculated from data your phone already tracks, so turning it on does not create extra battery drain.
Can I see the battery percentage on my lock screen?
On iPhone 12 and newer, you can add a battery widget to your lock screen that shows the percentage. Swipe left on your lock screen, tap the plus button, search for Battery, and add the widget. On older iPhones, the percentage does not appear on the lock screen — only in the status bar when your phone is unlocked.
What does it mean if the percentage jumps up or down suddenly?
Large jumps usually mean your phone is recalibrating its battery estimate. This can happen after a software update or if your phone has been off for a long time. Smaller fluctuations (1 to 3 percent) are normal and reflect actual power use. If the percentage drops 10 percent in a few seconds, a power-hungry app or feature may have just started running.
