My iPhone is saying in notifications that is 65 percent when is only at 13

Greetings dimi193,

Ensuring your battery percentage is showing correctly is important and you've come to a great place for help! If you haven't already, restart your iPhone using the steps listed below. You can also find these steps in the following article. Restarting is a great step that can help resolve many issues.

1. "Press and hold either volume button and the side button until the power-off slider appears.
2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

Restart your iPhone

If you continue to have issues after those steps, you'll want to confirm that iOS is updated to the latest version. The steps for updating can be found in the following article.
