Where to find the battery percentage setting

The battery percentage display on your iPhone shows you the exact charge level in the top-right corner of your screen, next to the battery icon. To turn it on, open Settings, then tap Battery, then tap Battery Health & Charging. At the top of that screen, toggle Battery Percentage to the on position (it will turn green).

Once enabled, the percentage appears when ready in your status bar. You do not need to restart your phone or close any apps — the change takes effect right away.

Key Takeaways

  • Battery percentage is found in Settings > Battery > Battery Health & Charging, where you toggle it on with a single tap.
  • The percentage displays in the top-right corner of your screen next to the battery icon once enabled.
  • The setting works on all iPhone models running iOS 16 or later.
  • Turning on battery percentage does not drain your battery or affect phone performance.

Why you might want to see the exact percentage

The battery icon alone shows you roughly how much charge remains — full, three-quarters, half, quarter, or nearly empty — but it does not tell you whether you have 45% or 38% left. Seeing the exact number helps you decide whether to charge now or wait, especially if you are away from a charger for the rest of the day.

Many people turn on battery percentage when they first get an iPhone or when they start paying closer attention to how fast their battery drains during certain activities. It takes up minimal screen space and gives you information the icon cannot.

What the percentage display looks like

Once enabled, you will see a number like "87%" or "42%" displayed in white text in the status bar at the top right of your screen. It sits directly to the left of the battery icon. On iPhone models with a notch or Dynamic Island, the percentage appears in the same area as the time and signal strength.

The percentage updates in real time as your phone uses power. You will see it drop by 1% every few minutes during normal use, and faster when you are using demanding apps like video or gaming.

Turning it off again if you change your mind

If you decide you do not want to see the percentage anymore, the process is identical: go to Settings > Battery > Battery Health & Charging, and toggle Battery Percentage to the off position. The number will disappear from your status bar when ready.

Some people turn it on only when they are concerned about battery life, then turn it off again once they feel confident about their charging habits. There is no penalty for toggling it on and off as often as you like.

Compatibility across iPhone models

Battery percentage display is available on all iPhone models running iOS 16 or later. If you have an older iPhone running iOS 15 or earlier, this setting does not exist — you will only see the battery icon. To check your iOS version, go to Settings > General > About and look for the number next to "Software Version."

If you are using an older iOS version and want the battery percentage feature, you would need to update your phone. Most iPhones from iPhone XS and newer can run the latest iOS versions.

Battery percentage and battery health

Watching your battery percentage drop does not harm your battery. The percentage is straightforward a readout of how much charge is currently stored. What matters for long-term battery health is how often you let your phone drain to very low levels and how you charge it — not whether you look at the number.

If you notice your battery percentage drops unusually fast, that can be a sign that your battery health is declining. You can check your actual battery health in the same Settings menu: go to Settings > Battery > Battery Health & Charging and look at the "Maximum Capacity" percentage. If it has dropped below 80%, your battery is aging and may need replacement eventually.

Frequently Asked Questions

Does turning on battery percentage use more battery?

No. The percentage is just a number displayed on your screen — it does not cause any extra power drain. Your battery will last the same amount of time whether you have the percentage visible or not.

Why does my battery percentage sometimes jump down suddenly?

Battery percentage can drop faster when you are using power-hungry apps like video streaming, gaming, or navigation. It can also drop faster in cold weather. Sudden large jumps (like from 40% to 20%) usually mean your battery health is poor and the phone's estimate is becoming less accurate — check your maximum capacity in Battery Health & Charging.

Can I see battery percentage on my lock screen?

The percentage appears in the status bar at the top of your screen on both the lock screen and home screen. On newer iPhones with a Dynamic Island, you can also add a battery widget to your lock screen for a larger display, though this is separate from the status bar percentage.

What if the battery percentage setting is not in my Settings menu?

This means your iPhone is running iOS 15 or earlier. The battery percentage feature was added in iOS 16. You can update your phone by going to Settings > General > Software Update and following the prompts, if your model supports it.
