Turn on the battery percentage indicator in Settings
Your iPhone can show you the exact battery percentage alongside the battery icon in the top-right corner of your screen. This takes about 30 seconds to turn on and works on most recent iPhone models.
Open the Settings app on your home screen. Scroll down and tap Battery, then tap Battery Health & Charging. Near the top of that screen, you'll see a toggle for Battery Percentage. Tap it to turn it on. The percentage will appear next to your battery icon when ready.
If you don't see a Battery Health & Charging option, your iPhone model may use a different path. Try opening Settings, then Control Center, then Customize Controls. Look for Low Power Mode in the list — if it's there, your phone supports the battery percentage display through Control Center instead.
Key Takeaways
- Go to Settings > Battery > Battery Health & Charging and toggle on Battery Percentage to see the exact number next to your battery icon.
- The percentage appears in the top-right corner of your screen next to the battery icon and updates in real time as you use your phone.
- Older iPhone models (iPhone 11 and earlier) may not have the Battery Health & Charging menu and will need to use Control Center instead.
- Once turned on, the battery percentage stays visible on your lock screen and home screen until you turn the toggle off.
- Displaying the battery percentage uses no extra power and does not affect your phone's performance or battery life.
Where the battery percentage appears on your screen
Once you turn on the setting, the percentage shows up in the status bar at the very top right of your screen. You'll see it on your lock screen, home screen, and in most apps — anywhere you can see the battery icon. The number sits right next to the battery icon itself, making it straightforward to glance at without opening any menus.
The number updates automatically as your battery drains or charges. If your phone is plugged in, you'll see the percentage climb as it charges. When your battery gets low, the percentage turns red to match the low battery warning, giving you a visual cue that you need to find a charger soon.
The percentage display is consistent across all your screens and doesn't change based on what app you're using or what you're doing on your phone. Whether you're on the home screen, in an app, or on the lock screen, the battery percentage remains visible in that same top-right corner.
What to do if the setting doesn't appear
iPhone 11 and earlier models don't have the Battery Health & Charging menu. If you own one of these phones, you can still see your battery percentage, but you'll access it through Control Center instead of Settings.
Swipe down from the top-right corner of your screen to open Control Center. The battery percentage appears at the top of that panel. You won't see it in the status bar itself, but you can check it any time by opening Control Center. This method works just as well — you just have to take one extra step to see the number.
If you have an iPhone 12 or newer and still don't see the Battery Health & Charging option, restart your phone. Hold down the side button and either volume button until the power-off slider appears, then slide to power off. Wait 10 seconds, then hold the side button again until you see the Apple logo. After the restart, go back to Settings and check whether the Battery Health & Charging menu is now visible.
Turning the battery percentage off again
If you decide you don't want the percentage displayed, the toggle works both ways. Go back to Settings > Battery > Battery Health & Charging and tap the Battery Percentage toggle to turn it off. The number will disappear from your status bar when ready.
Some people turn it off to reduce visual clutter or because they prefer to check battery status only when they open Control Center. There's no performance benefit to either choice — it's purely a display preference. You can turn it on and off as many times as you want without any impact on your phone.
Why you might want to see the exact percentage
Knowing your exact battery percentage helps you decide when to charge your phone. Instead of guessing based on the battery icon shape, you can see that you're at 23 percent and plan to find a charger before it drops further. This is especially useful if you're heading out and want to know whether you have enough charge to make it through the day.
The percentage is also useful if you're troubleshooting battery drain. If your phone is losing 5 percent per hour when you're not using it, that's a sign something is running in the background. Watching the percentage helps you spot the problem and figure out which app or process is using power.
For people who charge their phones multiple times a day, the percentage display makes it easier to track how much charge you've used since your last charge. You can see at a glance whether you're at 80 percent or 30 percent without having to open any settings.
Frequently Asked Questions
Does showing the battery percentage drain my battery faster?
No. The percentage display is just a number on your screen and uses no extra power. Your battery life will be the same whether the percentage is visible or hidden.
Can I see the battery percentage on my lock screen?
Yes. Once you turn on the setting, the percentage appears in the status bar at the top of your lock screen just like it does everywhere else on your phone. You don't need to unlock your phone to see it.
What if the percentage shows 100 but my phone feels slow?
A full battery doesn't mean your phone is running at full speed. If your phone is slow even at 100 percent, the issue is something else — too many apps running, storage full, or a background process using CPU power. The battery percentage only tells you how much charge you have left.
Does the percentage display work in Low Power Mode?
Yes. Low Power Mode and the battery percentage display are separate settings. You can have one on, both on, or both off. The percentage will show correctly no matter which power mode you're in.
Why does my battery percentage sometimes jump down suddenly?
Battery percentages can drop quickly when your phone is doing heavy work like downloading large files, running demanding apps, or charging while in use. This is normal. The percentage will stabilize once the heavy task finishes.
