Looking at a tiny battery icon and trying to guess whether you have 37% or 22% remaining isn't particularly helpful.
Fortunately, your iPhone can show the exact battery percentage.
Depending on your iPhone model and how you prefer to use it, you can see battery percentage:
- In the status bar
- In Control Center
- With a Home Screen widget
- With a Lock Screen widget
Here's how to set it up.
Method 1: Show Battery Percentage in the Status Bar
This is the easiest option if you want your remaining battery percentage visible throughout the day.
Open:
Settings → Battery
Then turn on:
Battery Percentage
That's it.
Your iPhone will now display the remaining battery percentage in the status bar.
On supported iPhones with Face ID, the percentage appears inside the battery icon.
How to Turn Battery Percentage Off
If you decide you don't like having the number displayed constantly, return to:
Settings → Battery → Battery Percentage
and turn it off.
You can still check the exact percentage through Control Center whenever you need it.
Method 2: Check Battery Percentage in Control Center
You don't actually need Battery Percentage permanently enabled to see your exact remaining charge.
On an iPhone with Face ID:
Swipe down from the top-right corner of the screen.
Control Center opens and displays your battery information near the top of the screen.
This is useful if you prefer the cleaner battery icon in the status bar but occasionally want to know the exact percentage.
Why Isn't My Battery Percentage Showing?
First check:
Settings → Battery → Battery Percentage
Make sure the setting is enabled.
If you still don't see what you expect, remember that the appearance of battery information can vary depending on:
- iPhone model
- iOS version
- Display configuration
- Where you're viewing the battery information
You can always open Control Center to quickly check the remaining percentage.
Method 3: Add the Batteries Widget to Your Home Screen
If you want more battery information than a small percentage in the corner of the screen, use Apple's Batteries widget.
The widget can show battery information for your iPhone and supported connected accessories.
That makes it particularly useful if you regularly use devices such as:
- AirPods
- Wireless headphones
- Other compatible Bluetooth accessories
Instead of checking each device separately, you can monitor several battery levels from one place.
How to Add the Batteries Widget
From your Home Screen:
- Touch and hold an empty area of the Home Screen.
- Enter Home Screen editing mode.
- Choose the option to add a widget.
- Search for Batteries.
- Select the widget size you prefer.
- Add it to your Home Screen.
- Position it where you want it.
The exact interface can vary slightly depending on your version of iOS, but the Batteries widget remains the feature you're looking for.
Why Use the Batteries Widget?
The widget becomes especially useful once your Apple setup grows beyond just an iPhone.
Instead of wondering:
How much battery do my AirPods have left?
you can glance at the widget.
It's also considerably easier to read than a tiny status-bar icon.
Method 4: Add Battery Information to Your Lock Screen
You can also use battery-related widgets on supported Lock Screen configurations.
This gives you battery information without needing to open an app.
Depending on your configuration and connected devices, the widget can provide quick battery status directly from the Lock Screen.
If you frequently check battery levels throughout the day, this can be more convenient than opening Settings or Control Center.
Why Did Apple Remove the Old Battery Percentage?
Older iPhones had more physical space around the status-bar area.
When Apple introduced iPhones with Face ID and the display cutout, available status-bar space changed significantly.
That changed how information such as battery percentage could be displayed.
Modern versions of iOS once again allow supported Face ID iPhones to show the percentage directly inside the battery symbol.
So if you remember battery percentage behaving differently on an older iPhone, you're not imagining things.
The interface changed over time.
What Does the Yellow Battery Icon Mean?
If your battery icon turns yellow, Low Power Mode is enabled.
Low Power Mode reduces certain activities and features to help extend remaining battery life.
That doesn't mean your battery is damaged.
It simply means your iPhone is operating in a power-saving mode.
If you're running low and need your phone to last several more hours, Low Power Mode can be extremely useful.
Does Showing Battery Percentage Drain the Battery?
Not in any meaningful way you should worry about.
Displaying the percentage is simply giving you a more precise representation of information your iPhone already monitors.
You don't need to hide the percentage because you're concerned that displaying the number itself will significantly reduce battery life.
If you're trying to improve runtime, focus on things that actually consume substantial power.
For example:
- Screen brightness
- Heavy applications
- Poor cellular reception
- Location usage
- Background activity
- Gaming
- Video
- Navigation

25 Ways to Improve iPhone Battery Life and Stop Battery Drain
Does Checking Battery Percentage Constantly Help?
Technically, you can check it as often as you want.
Practically?
Don't turn it into a scoreboard.
Watching your battery change from:
78% → 77% → 76%
doesn't tell you much by itself.
Battery consumption changes throughout the day depending on what you're doing.
Streaming video for an hour will consume considerably more power than leaving your iPhone sitting on a desk.
If you're concerned that the battery is actually draining too quickly, don't stare at the percentage.
Open:
Settings → Battery
and investigate what's using the power.

Why Does My Battery Percentage Drop Quickly?
If you're watching the percentage and notice it falling much faster than expected, investigate the cause.
Possible explanations include:
- Heavy screen usage
- Gaming
- Video streaming
- Navigation
- Camera usage
- Background activity
- Poor cellular signal
- Excessive heat
- An aging battery
- Activity after an iOS update
Battery percentage tells you how much charge remains.
It doesn't tell you why that charge disappeared.
For that, you need Battery Usage.
Check What's Using Your Battery
Open:
Settings → Battery
Your iPhone can provide information about battery usage by apps and system activity.
This is far more useful for troubleshooting than simply monitoring the percentage in the status bar.
If an app is responsible for an unusually large amount of usage, investigate that application.
If you see significant background activity, read:

What If Battery Drain Started After an iOS Update?
This is another situation where watching the percentage can make users nervous.
You install an update.
The phone restarts.
Then you notice the battery percentage falling faster than usual.
Your iPhone may still be performing update-related work in the background.
Before assuming something is wrong, read:

That guide explains what to check in Battery settings and when post-update drain deserves further investigation.
Battery Percentage vs. Battery Health
These are completely different measurements.
Battery Percentage
This tells you how much charge is currently remaining.
For example:
72%
means your battery currently has an estimated 72% of its available charge remaining.
Battery Health
Battery Health describes the condition and capacity of the physical rechargeable battery as it ages.
A battery can show:
100% charge
while no longer having the same physical capacity it had when it was brand new.
That's because 100% means:
100% of the battery's current available capacity.
It doesn't necessarily mean the battery is physically identical to a new one.
For a full explanation, read:
How to Check iPhone Battery Health and What It Really Means
Why Does My iPhone Say 100% but Die Faster Than It Used To?
This is where Battery Health becomes important.
Imagine a battery could store 100 units of energy when new.
Years later, chemical aging means it can only store 80 units.
When that older battery is completely charged, your iPhone can still display:
100%
because the battery is completely charged relative to its current capacity.
But there's less total energy available than there was when the battery was new.
That's why an older iPhone can reach 100% normally but not last as long.
See:
How Long Does an iPhone Battery Last?
Does Battery Percentage Become Less Accurate as the Battery Ages?
Battery percentage is an estimate based on information from the battery-management system.
If your battery behaves strangely—for example:
- Dropping suddenly from one percentage to another
- Shutting down despite showing charge remaining
- Showing extremely inconsistent runtime
check Battery Health and overall battery condition.
Don't immediately follow internet advice telling you to repeatedly drain the battery to zero.
We've covered that misconception in:
Do You Need to Calibrate Your iPhone Battery? Myths vs. Facts
What If My Battery Percentage Stops at 80%?
That's usually a charging question rather than a battery-percentage-display problem.
Your iPhone includes charging-management features that may intentionally affect when and how the battery charges beyond certain levels.
Temperature can also affect charging behavior.

Why Is My Battery Icon Red?
A red battery icon generally indicates that your remaining battery level is very low.
Connect your iPhone to a charger when practical.
If the phone refuses to charge even when connected, that's a separate troubleshooting problem.

Should You Keep Battery Percentage Turned On?
This comes down entirely to preference.
Leave It On If:
- You like knowing the exact remaining charge.
- You frequently spend long periods away from chargers.
- You use Low Power Mode strategically.
- You prefer precise information.
Leave It Off If:
- You prefer a cleaner status bar.
- You find yourself obsessively monitoring the number.
- The battery icon provides enough information for you.
Neither choice improves the physical health of your battery.
It's simply an interface preference.
