Where to find the battery percentage setting on your iPhone

Your iPhone can show battery life two ways: as a small icon in the top right corner, or as a number like "87%". The setting to switch between them lives in Settings under Battery, and the exact steps depend on which iPhone model you own.

On iPhones with Face ID (iPhone X and newer, including all current models), the battery percentage appears in the status bar at the top of the screen. On iPhones with a home button (iPhone 8 and earlier), it shows in the top right corner next to the signal strength. Either way, you control it from the same menu.

Key Takeaways

  • Open Settings, tap Battery, then tap Battery Percentage to turn the number display on or off.
  • On iPhones with Face ID, the percentage shows in the status bar at the top; on older models, it appears in the top right corner.
  • The setting takes effect when ready — you do not need to restart your phone.
  • Turning on battery percentage uses slightly more screen space but gives you a precise reading instead of an estimate.

Step-by-step: turning on battery percentage

Open the Settings app (the gray gear icon on your home screen). Scroll down and tap Battery. You will see a section called Battery Health & Charging near the top, and below that a toggle labeled Battery Percentage. Tap the toggle to turn it on. The switch will turn green, and the percentage will appear in your status bar when ready.

If you do not see a Battery Percentage option, your phone is running an older version of iOS. You can still see the percentage by swiping down from the top right corner to open Control Center — the battery percentage displays there regardless of your settings.

Why you might want to see the percentage

The icon alone does not tell you how much battery you actually have left. A battery icon that looks half-full might mean 60% or 40%, depending on how your phone draws it. The percentage number removes that guesswork, so you know exactly when to charge.

Seeing the number also helps you notice patterns — if your battery drains much faster than it used to, that can signal a hardware problem worth investigating. Many people turn on the percentage when they suspect a battery is aging and want to track the decline.

What happens if you turn it off again

If you decide you prefer the icon-only view, go back to Settings > Battery and toggle Battery Percentage off. The number will disappear from your status bar, and you will see only the icon. This change is when ready and does not affect anything else on your phone.

Some people turn the percentage on temporarily to diagnose a battery problem, then turn it off once they have the information they need. There is no penalty for switching back and forth.

Battery percentage on older iPhones without the setting

If you own an iPhone 6s, 7, 8, or earlier, your Settings app may not have a Battery Percentage toggle. On these models, you can still see the percentage by opening Control Center — swipe down from the top right corner (or up from the bottom on older models with a home button). The battery percentage displays there in large text.

You can also check the percentage in the Battery section of Settings itself: open Settings, tap Battery, and the percentage appears at the top of the screen. It is not in the status bar, but you can see it whenever you need to.

When battery percentage display is most useful

The percentage is especially helpful when you are away from a charger for a long time — you can make real decisions about whether to use your phone for video, maps, or just calls based on the actual number. It is also valuable if you are troubleshooting battery drain, because you can watch how fast the percentage drops during normal use.

Some people find the percentage distracting and prefer the simpler icon view. Neither choice is wrong — it comes down to whether you want precision or a cleaner status bar.

Frequently Asked Questions

Does showing the battery percentage drain the battery faster?

No. The percentage is just a different way of displaying information your phone is already tracking. Turning it on or off has no effect on how long your battery lasts.

Why does my battery percentage sometimes jump from one number to another?

iOS calculates battery percentage based on voltage and other factors, and those readings can shift slightly as your phone adjusts power use. A jump of a few percent is normal and does not mean your battery is failing.

Can I see the battery percentage on the lock screen?

On iPhones with Face ID, the percentage shows in the status bar at the top of the lock screen. On older models, you have to unlock the phone or open Control Center to see it. Some third-party lock screen widgets can display it, but the built-in setting does not put it on the lock screen itself.

What if the battery percentage shows 100% but my phone shuts down?

This usually means the battery is aging and cannot hold a full charge anymore, even though iOS reports it as full. The phone may also be in low-power mode, which limits performance. Consider having the battery checked by Apple or an authorized repair shop if this happens repeatedly.
