My iPhone Battery is Yellow – What Does it Mean?

However, that is not the case. Your iPhone’s battery displaying as yellow does not mean anything is wrong.

Stick with us as we discuss what is actually happening.

Why is My iPhone Battery Yellow?

When the iPhone battery icon is yellow, it means that your iPhone has entered Low Power Mode and the battery is running low and needs to be charged. Typically, your iPhone battery icon will turn yellow when the battery life hits 20%. This is to indicate your iPhone will soon run out of battery.

You’re most likely used to your iPhone battery icon displaying red, not yellow.

What is Low Power Mode On iPhone?

Low power mode is a feature on iPhones that helps to extend the battery life of the device. When low power mode is enabled, some of the phone’s features are disabled or reduced in order to save battery power. This is another reason your iPhone battery icon is displaying as yellow. Your iPhone has entered Low Power Mode in order to extend the battery life.

When enabled, low power mode reduces screen brightness, disables certain visual effects, and minimizes system animations. It can be enabled manually by the user, or automatically when the phone’s battery reaches a certain level.

How to Disable Low Power Mode

There are a few different ways to disable low power mode on an iPhone. One way is to simply go into the Settings app and toggle the feature off.

How Long Can iPhones Go Without a Charge?

As far as phone batteries go, the iPhone battery is pretty good. It’ll last most people through a full day of use, and then some. Even with relatively heavy use, you should still be able to get a full day out of it. Of course, your mileage may vary depending on how you use your iPhone.

If you’re looking for ways to extend your battery life even further, there are a few things you can do. For example, dimming your screen will help save power.

What Are iPhone Batteries Made Out Of?

iPhone batteries are made using lithium-ion technology. This type of battery is known for its high energy density, which means that it can store a lot of energy in a small space. Lithium-ion batteries are also very lightweight, making them ideal for use in portable electronic devices.

The downside of lithium-ion batteries is that they can be expensive to produce, and they can be dangerous if they are not used properly. Lithium-ion batteries have been known to catch fire if they are damaged or overheated.

How Long Does It Take An iPhone To Fully Charge?

It usually takes around two hours to fully charge an iPhone. If you’re in a hurry, there are several ways to speed up the process. For example, you can use a higher wattage power adapter or plug your iPhone into a computer.


When an iPhone’s battery icon turns yellow, it can be alarming because we don’t typically see that color associated with batteries.

However, there’s no need to worry; in most cases, it just means that your iPhone has entered Low Power Mode and your device needs to be charged soon.

In the event that your iPhones actual battery turned yellow, the battery is old and needs to be replaced. The yellow color is caused by a chemical reaction that takes place inside the battery as it starts to wear out. This reaction causes the battery to produce a small amount of hydrogen gas, and the hydrogen gas can cause the battery to swell up and turn yellow.

If your iPhone’s battery has turned yellow, you should replace it as soon as possible. Swollen batteries are dangerous and can explode if they’re not handled properly. If your iPhone starts to smell like rotten eggs, or if you notice any other strange behavior, take it to an Apple Store or another authorized service center for repair.

  1. I read this article because my battery indicator turned yellow while my iPhone was plugged into the charger and was showing 100%. I went and turned off low power as recommended but I’m still confused why the battery indicator went yellow while plugged in. It’s an iPhone 7+, running iOS 15. The battery indicator now shows black where it used to show green.

    • There are a few potential reasons for why this might have happened. One possibility is that your iPhone was in Low Power Mode when it was plugged in. Low Power Mode conserves battery power by reducing performance and disable certain features. This can cause the battery indicator to turn yellow.

      Another possibility is that your iPhone is not charging properly. If the charging port or cable is damaged, it can cause the battery indicator to turn yellow. You can try cleaning the charging port with a soft cloth to see if that helps.

      If your iPhone is still under warranty, you may want to take it to an Apple Store or authorized service provider to have it checked out.

  2. My phone has not been on low battery and I checked the settings. Low Power mode is not on. The phone is fully charged and it is still yellow.

    • Low Power Mode is a feature that Apple introduced in iOS 9 to help conserve battery life.
