Why is my battery bar yellow? Understanding iPhone’s Low Power Mode


Michael Collins

Have you ever glanced at your phone and noticed that the battery bar is yellow instead of the usual green or red? If so, you might be wondering why that is. Well, it’s actually a feature on your phone called Low Power Mode. This mode is your phone’s way of telling you that it’s conserving battery life. In this article, I’ll explain what Low Power Mode is, how to turn it on and off, and what happens when it’s activated.

Step by Step Tutorial: Why is my Battery Bar Yellow

Before we dive into the steps, it’s important to understand what we’re trying to accomplish. Activating Low Power Mode can help your phone’s battery last longer when it’s running low. It reduces the amount of power that your phone uses by turning off some features and reducing others.

Step 1: Check Your Battery Percentage

The first thing you want to do is check your battery percentage. If it’s below 20%, your phone may automatically switch to Low Power Mode, which changes the battery bar to yellow.

When your phone switches to Low Power Mode, it’s trying to save energy so you can use your phone for a longer period of time. You can still use your phone, but some features might not work as well as they do when Low Power Mode is off.

Step 2: Turn Low Power Mode On or Off Manually

If you want to turn Low Power Mode on or off manually, go to "Settings," then "Battery," and toggle the "Low Power Mode" switch.

Turning Low Power Mode on can be a great way to extend your battery life when you know you won’t be able to charge your phone for a while. Just remember that some features might be limited.

After you complete these steps, your battery bar will either remain yellow if Low Power Mode is on, or it will return to its normal color if you’ve turned it off. Either way, you’ll have a better understanding of what that yellow battery bar means.
