Where to Find Your Battery Percentage on iPhone
Your iPhone shows battery percentage in the top-right corner of your screen, next to the battery icon. On newer iPhones with a notch or Dynamic Island, swipe down from the top-right to open Control Center — the battery percentage appears there in large numbers. On older iPhones with a home button, swipe up from the bottom to open Control Center and see the percentage displayed.
If you do not see a percentage number in the status bar, your phone is set to show only the battery icon. You can turn on the percentage display in Settings so it appears all the time, which takes about 30 seconds.
Key Takeaways
- Battery percentage appears in the top-right corner of your screen on iPhones without a notch, or in Control Center on newer models.
- You can enable a permanent percentage display in Settings > Battery > Battery Percentage so you always see the exact number.
- Control Center shows battery percentage when ready on any iPhone model — swipe down from the top-right (notch models) or up from the bottom (home button models).
- Low Power Mode reduces battery drain and appears in Control Center; turning it on extends your phone's runtime by roughly one hour per charge.
Turn On Battery Percentage in Settings
Open the Settings app and tap Battery. Then tap Battery Percentage and toggle it on. The percentage will now appear in the status bar at the top of your screen at all times, next to the battery icon.
This setting works on iPhone 11 and newer. If you have an older iPhone, the percentage option may not appear in Settings — in that case, Control Center is your fastest way to check the exact number.
Check Battery in Control Center
Control Center is the quickest way to see your battery percentage without opening Settings. On iPhones with a notch or Dynamic Island (iPhone 12 and newer), swipe down from the top-right corner of the screen. On iPhones with a home button, swipe up from the bottom of the screen. Your battery percentage appears in large text at the top of the Control Center panel.
Control Center also shows you which apps are using the most battery. Swipe down again or tap outside the panel to close it. This method works on every iPhone model and takes less than one second.
Understand the Battery Health Section
If you want to know how much your battery has degraded over time, go to Settings > Battery > Battery Health & Charging. This screen shows Maximum Capacity — the percentage of your battery's original charge that it can still hold. A new iPhone shows 100%; after a year or two of normal use, it typically drops to 80 to 90%.
The same screen shows Cycle Count, which is the number of times your battery has charged from 0 to 100%. Each full cycle counts as one, so charging from 50% to 100% counts as half a cycle. This information is useful if you are deciding whether to replace your battery, but it does not affect how you check your current percentage.
Use Low Power Mode to Extend Battery Life
When your battery is low, turn on Low Power Mode to reduce power drain. Open Control Center and tap the battery icon (it looks like a lightning bolt inside a circle). Low Power Mode limits background activity, reduces screen brightness slightly, and slows down performance — but it can add roughly one hour of runtime to a single charge.
Low Power Mode turns off automatically when your battery reaches 80% after charging. You can also turn it on manually at any battery level if you know you will not have access to a charger for a while. The setting appears in Control Center and also in Settings > Battery > Low Power Mode.
Common Mistakes When Checking Battery
The most common mistake is looking only at the battery icon without the percentage. The icon fills with color as your battery drains, but it does not show exact numbers — a battery that looks half-full might actually be at 40% or 60%. Always check the percentage number to know how much time you have left.
Another mistake is forgetting that Control Center closes automatically after a few seconds if you do not tap anything. If you swipe down and then look away, the panel disappears. Swipe again to reopen it, or enable the percentage display in Settings so you can see it without opening Control Center.
Frequently Asked Questions
Why does my iPhone show a battery icon but no percentage number?
Your phone is set to show only the icon. Go to Settings > Battery > Battery Percentage and turn it on. If that option does not appear, you have an older iPhone model — use Control Center instead by swiping down from the top-right or up from the bottom.
What does it mean if my battery percentage is yellow or red?
Yellow means your battery is below 20%; red means it is below 10%. These colors are warnings that you should charge soon. At 0%, your phone shuts down automatically. Low Power Mode turns on automatically at 20% on some iPhone models.
Does checking my battery percentage drain the battery?
No. Looking at the percentage in Settings, Control Center, or the status bar uses almost no power. The only way to drain your battery faster is to use apps, play video, or keep your screen on for long periods.
Can I see what apps are using my battery?
Yes. Go to Settings > Battery and scroll down to see a list of apps ranked by battery use over the last 24 hours or the last 10 days. Tap the time period at the top to switch between them. This helps you find apps that drain power faster than expected.
