What does a yellow battery mean on iPhone?

Why is my iPhone battery yellow on battery status bar?

I have come across many iPhone users anxiously asking the question – why is my iPhone battery yellow on the battery status bar? Here in this post, I am going to explain what does a yellow battery mean on iPhone. But before that let’s first look into why the iPhone battery icon changes color.

Why iPhone battery icon changes color?

The iPhone battery icon on the status bar should normally remain white when it’s not charging and the charge is over 20%. Whenever the battery charge drops below 10 percent the iPhone charging symbol turns ‘red’ indicating that the phone battery needs immediate charging otherwise, your iPhone may go ‘power off’ at any time soon.

The iPhone charging symbol turns ‘green’ on the battery status bar when your phone is plugged in for charging.

Now let me answer your query – why is my iPhone battery yellow colour and what does a yellow battery mean on iPhone?

Why is my iPhone battery yellow on the battery status bar? 

You may sometimes hear from iPhone users – why is my battery yellow on my iPhone? If at any time you see the iPhone yellow battery icon on the battery status bar, you should not worry as the yellow battery indicator on iPhone does not indicate anything wrong or malfunctioning of your device. Then what does yellow color on iPhone battery mean?

There is an important feature in your iPhone called ‘Low Power Mode’ which has been added by Apple to save battery power. When this iPhone power saving mode is enabled it turns the iPhone battery icon yellow. Battery percentage also appears on the status bar along with the yellow battery icon.

Now that you got the answer to your query – why is my iPhone battery yellow colour, now let’s see what is the significance of ‘iPhone Low Power Mode’.

Why use iPhone Low Power Mode?

The iPhone Low Power Mode feature is useful when the battery level of your iPhone is low. Whenever the battery gets low this iPhone power-saving mode extends the life of the battery and prevents it from completely dying out before you recharge your phone. In this mode, your iPhone continues to operate for a longer period with a low battery by consuming less power through some changes in the functionalities in some of the high-demand features of the device. As already mentioned when Low Power Mode is on, the yellow battery indicator on iPhone appears and you’ll see the battery percentage.

This ‘Low Power Mode’ feature of your iPhone automatically turns ‘on’ when the battery goes below 20% when you will see the iPhone yellow battery icon on the status bar. Again after your iPhone battery is charged to 80% or higher, ‘Low Power Mode’ automatically turns off. You can also enable this ‘power saving mode’ manually in the battery options in settings, to save battery usage. When your device reaches 20% in battery power left you will receive a ‘low battery power’ message prompting you to activate the ‘Low Power Mode’.

Therefore, the appearance of the iPhone battery yellow icon and battery percentage on the status bar could mean that the ‘Low Power Mode’ is made ‘on’ either automatically or manually or by selecting ‘yes’ when a prompt appears asking if you wish to place your device in ‘Low Power Mode’.

However, when this feature is on, some of the iOS features like mail fetch, Hey Siri, Background app refresh, Automatic downloads, and some visual effects, are reduced or turned off. To get the most out of Low Power Mode, there are a few other practical tips you can use to squeeze even more life out of your battery:

• Use widgets wisely: Some widgets are sneakily power-hungry and can drain your battery faster than you realize.
• Disable Background App Refresh for apps you rarely use to further minimize background activity.
• Limit Location Services: GPS and location tracking can use a surprising amount of battery, so consider turning off Location Services for apps that don’t need it.
• Check your battery health: If your battery’s maximum capacity is under 80%, it might be time to consider a battery replacement for optimal performance.

Related tips for maintaining your iPhone battery:

• How to Keep iPhone Battery Health: Regularly update your iOS, avoid extreme temperatures, and try not to let your battery drain completely before recharging.
• How to Check iPhone Battery Health: Go to Settings > Battery > Battery Health & Charging to view your battery’s maximum capacity and peak performance capability.
• How to Replace an iPhone Battery Yourself: If you’re comfortable with DIY repairs, there are online guides and kits available, but for most users, it’s safer to visit an Apple Store or authorized service provider.

By combining Low Power Mode with these simple steps, you can help your iPhone last longer between charges, especially when you need it most.

 Power saving mode iPhone – how to turn it on or off 

Let us now look into how to enable or disable the power-saving mode iPhone.

In order to turn the ‘iPhone Low Power Mode’ ‘ON’ or ‘OFF’, go to Settings > Battery > then toggle the slider to the ‘ON’ or ‘OFF’ position. When you enable this feature i.e. Make it on, the iPhone yellow battery icon appears on the status bar. When you disable the feature i.e. Turn it ‘off’ you will see the battery icon turning from yellow to white or red depending on the percentage of the battery remaining on your phone.

Quick ways to manage Low Power Mode:

• Ask Siri: You can simply say, “Turn on Low Power Mode” or “Turn off Low Power Mode,” and Siri will do it for you.
• Use Control Center: For quicker access to Low Power Mode, you can also add it to the Control Center. To do this, go to Settings > Control Center > Customize Controls, then select Low Power Mode to add it. Now, just swipe up from the bottom of the screen and tap the battery-like button to enable or disable Low Power Mode.
• Check Status: If you ever want to confirm whether Low Power Mode is active, just open Settings > Battery and look at the toggle.

This makes it much easier to swap between power-saving and regular modes, especially if you find yourself frequently running low on battery.

Automating Low Power Mode with Shortcuts

If you want your iPhone to switch to Low Power Mode automatically—say, whenever you leave the house or at a certain battery percentage—you can set this up with Apple’s Shortcuts app. It’s a handy way to streamline your routines and never get caught off guard by a dying battery.

Here’s how to get started:

• Open the Shortcuts app on your iPhone.
• Tap on the Automation tab at the bottom.
• Tap “Create Personal Automation.”
• Choose your trigger—for instance, Battery Level (e.g., when your battery hits 30%) or Time of Day, or even When Leaving Home.
• Set the action: Tap “Add Action,” then search for “Set Low Power Mode.” Choose to turn it On or Off as you like, then tap Next.
• You can also disable the “Ask Before Running” toggle so the automation works without any prompt.
• Tap Done to save.

Now, whenever your chosen condition is met, your iPhone will enter (or exit) Low Power Mode automatically. It’s a set-it-and-forget-it solution for stretching your battery life with zero extra effort.
