Why Is My iPhone Battery Yellow? Understanding the Low Power Mode

Have you ever looked at your iPhone and noticed that the battery icon is suddenly yellow instead of the usual green or red? Don’t panic! This color change is a feature of your iPhone, and it’s called Low Power Mode. It’s designed to help extend your battery life when it’s running low. In this article, we’ll walk you through what causes the yellow battery icon and how to turn Low Power Mode on and off.

Step by Step Tutorial: Turning On and Off Low Power Mode on iPhone

Before diving into the steps, let’s understand what we’re aiming for. Turning on Low Power Mode will change your battery icon to yellow and reduce power consumption by disabling some features and reducing performance. Turning it off will return your phone to its normal state with full functionality.

Step 1: Access Your Control Center

Swipe up from the bottom of the screen (or down from the top-right corner on an iPhone X or later) to access your Control Center.

The Control Center is like a shortcut hub on your iPhone. It allows you to quickly turn on and off many features without digging through the Settings app.

Step 2: Locate the Battery Icon

Look for the battery icon in the Control Center. It looks like a small battery with a percentage next to it.

This icon represents your current battery status and, when tapped, will toggle Low Power Mode on or off.

Step 3: Enable or Disable Low Power Mode

Tap the battery icon to turn Low Power Mode on or off. The icon will turn yellow when it’s on.

When Low Power Mode is enabled, your iPhone will reduce its performance and disable some features like mail fetch, background app refresh, and some visual effects to save battery life.

After completing these steps, your iPhone will either enter Low Power Mode to save battery or turn it off to return to normal functionality. The battery icon will appear yellow when Low Power Mode is on and will switch back to green or red when it’s off, depending on your charge level.

  • Dim your screen brightness or enable Auto-Brightness to conserve power.
