Why Is My iPhone Battery Icon Yellow?

The icons and status indicators at the top of your iPhone screen can tell you a lot of important information, provided that you know what everything means. So you may be wondering why your iPhone battery icon is yellow if you are used to it being a different color.

You are probably familiar with the different stages of display that your iPhone’s battery icon can enter. It is green when it is fully charged, red when almost empty, and white or black any other time, depending upon the background color of your screen. But iOS 9 brings a new option, as your battery icon can be yellow when you have enabled Low Power mode.

Low Power mode is a great addition for iPhone users that often deplete their battery quickly, or for users that have iPhones with dying batteries. But you may not have purposely enabled Low Power mode, or you might dislike the yellow battery enough that the battery life gains from Low Power mode are not important enough. Our tutorial below will show you where to find Low Power Mode so that you can turn it off and stop your battery icon from being yellow.

Turning Off Low Power Mode in iOS 9

The steps in this article were performed with an iPhone 6 Plus, in iOS 9. These steps and the information contained in this article also hold true for iOS 10.

If you are reading this article because you have a yellow battery icon on your iPhone and you don’t know where it came from, then it is likely that you didn’t enable Low Power Mode intentionally. Aside from the method for enabling or disabling this setting that is discussed in the steps below, it can also be turned on via a pop-up window that displays automatically when your iPhone reaches 20% battery life or lower. That screen looks like the image below –

Regardless of whether the yellow battery indicator appeared because Low Power Mode was enabled through this pop-up or through the manual method outlined below, the method for disabling it is the same.

This guide will show you how to disable the Low Power mode to change your iPhone battery color from yellow back to either the black, red, green or white color that it typically is. This is going to result in your battery life draining more quickly than it did when Low Power Mode was enabled. You can still make some adjustments that will help to improve battery life when you aren’t in Low Power mode, however, such as disabling Background App Refresh.

Note that it is normal for the capacity to drain over time as the phone and the battery both get older. If the bottom of this menu indicates that the battery is performing at peak capacity, then your battery is likely in good shape.
