Why is My Battery Yellow on My iPhone [iPhone 14 Supported]

Gorilla updated on Dec 29, 2022 to iOS & Mac Topics

Rechargeable lithium-ion batteries are widely used in all mobile device industries, including iPhone and Android devices, enabling you to do all operations on your devices everywhere. Lithium-ion batteries weigh lighter, last longer, and charge more effectively than older battery types. So lithium-ion batteries offer the best performance so far, compared to other types.

In the course of using our phones with the support of the battery, we can do all kinds of operations. However, sometimes, we would find that the battery color in the upper-right corner of our iPhone has become yellow. So why is my battery yellow on my iPhone/iPad? Now let's explore it together!

Part 1. Why is My Battery Yellow on My iPhone/iPad

If you find that your iPhone's battery icon has turned from white to yellow, don't worry. There's nothing wrong with your iPhone or the battery. The yellow icon means that the Low Power Mode is currently enabled on your iOS device. It's just the signal that you have turned the battery-saving mode on your iPhone. If your iPhone's battery icon turns yellow in a short time, this could be because you've turned on apps that use a lot of power and your iPhone would get hot. If your iPhone gets so hot and you don't know the reason, you can refer to "Why Does My New iPhone 7 Get So Hot".

Now let's explore why is my battery yellow on my iPhone!

1. What is Low Power Mode?

Once your iPhone's battery is running low, it will use less power when in Low Power Mode. Therefore, Low Power Mode is used to save battery life on your iPhone or iPad. After you charge your device over 80%, Low Power Mode will turn off and the yellow battery icon will turn back to white automatically.

If the battery has enough power to support your iPhone, but your iPhone shuts down at 50% battery suddenly, there must be something wrong with your iPhone. You can solve the problem by reading this article above.

2. How to use Low Power Mode?

Low Power Mode is expected to be enabled and your battery icon will turn yellow when you need to save your iPhone's battery power. Your phone system will prompt you about your low battery when your battery level goes down to 20% and ask you if you want to enable Low Power Mode to save charge.

Once you confirm it with one tap, the battery icon immediately turns yellow and the icon won't turn back to white until your battery charge is over 80%. When your phone charges up, Low Power Mode turns off automatically.

If you want to turn the Low Power Mode on manually even if the battery charge is enough to use, that's feasible and practical. In this case, the battery icon remains yellow regardless of how much battery charge is left.

To enable/disable Low Power Mode, complete the following steps:

Step 1. Go to Settings > Control Center > Customize Controls.

Note: Alternatively, you can also go to Settings > Battery to turn the mode on/off.

Step 2. Then tap Low Power Mode to add it to Control Center.

That's all it takes to turn the Low Power Mode on or off. And you will find that the battery icon has turned to yellow once you enable the Low Power Mode.

Part 2. The impact of Low Power Mode

We've just learned why our battery is yellow on our iOS 16 or lower version and how to enable Low Power Mode to save our battery power. Then how does this mode work? If we turn it on, what will happen to our iPhone and what benefit do we get from the operation?

When you keep your iPhone in Low Power Mode, it has an impact on some features on your iPhone, including:

  • Disable 5G (excluding video streaming) on iPhone 12 models (iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max).
  • Turn the Auto-Lock time to 30 seconds.
  • Lower the Display Brightness if it's too strong before.
  • Temporarily pause the update of iCloud Photos.
  • Temporarily pause the automatic downloads.
  • Stop email fetches in real-time.
  • Stop background app refresh.

The decrease of these resources above is the secret that the Low Power Mode saves the battery charge on your iPhone.

Part 3. How to Maintain My Battery

All batteries age. It's only a matter of time. What we can do is try our best to maximize battery life and lifespan.

To maintain my battery for good performance:

  • Update to the latest software (iOS 14 or iOS 16 is strongly recommended).
  • Turn on Auto-Brightness to adjust your screen brightness automatically.
  • Enable Low Power Mode (the battery icon turns yellow).

Final Thoughts

Low Power Mode can easily extend your iPhone's battery life when it goes low. The yellow battery icon in the upper-right of the corner is also a pretty good visual feature for users to check if they keep their iPhones in Low Power Mode properly. In this way, you will know when your battery level goes down to 20%, and again at 10%.
