Have you noticed that your iPhone battery icon has suddenly turned yellow instead of its usual color? If you are wondering, why is my iPhone battery yellow, there is usually no need to worry. This color change normally means that Low Power Mode is enabled on your device.
Low Power Mode is a built-in iPhone feature designed to help your battery last longer when you cannot charge your phone immediately. It reduces certain background activities and adjusts some features to save power.
However, you might not know how it was activated, whether it affects your phone's performance, or how to turn it off.
In this guide, you will learn why your iPhone battery is yellow, how to turn off Low Power Mode, what happens when you use it, and what to do if the yellow battery icon keeps returning.
Quick Answer: Why Is My iPhone Battery Yellow?
Your iPhone battery icon is yellow because Low Power Mode is turned on. This feature reduces power consumption to help your battery last longer.
You can turn it off by following these steps:
- Open Settings on your iPhone.
- Tap Battery.
- On iPhone 14 and earlier models, tap Low Power Mode and turn it off.
- On iPhone 15 and later models, tap Power Mode, then turn off Low Power Mode.
Once you disable this feature, the battery icon should return to its normal appearance.
You can also turn off Low Power Mode through Control Center if the relevant control is available. Apple confirms that Low Power Mode automatically turns off when the battery reaches 80% or higher. Apple Support.
1. Why Is My iPhone Battery Yellow?
The most common reason your iPhone battery icon is yellow is that Low Power Mode has been activated.
This feature is useful when your battery is running low or you want to extend the time between charges.
For example, imagine that your iPhone has 25% battery remaining and you are travelling without access to a charger. Turning on Low Power Mode can help reduce power consumption until you reach a place where you can charge your phone.
When Low Power Mode is active, iOS changes the battery icon to yellow so you can easily recognize that the feature is enabled.
What Activates Low Power Mode?
There are several possible reasons.
- You enabled it manually: You may have switched it on through Settings or Control Center.
- You used a battery-saving shortcut: You might have activated it through Siri or an automation.
- Your iPhone enabled it through a supported feature: On compatible devices with Adaptive Power enabled, Low Power Mode can turn on automatically when the battery reaches 20%.
A yellow battery icon does not normally mean your battery is damaged, your iPhone has a virus, or your battery health is poor.
It simply indicates that Low Power Mode is active.
2. How to Turn Off the Yellow Battery Icon on iPhone
If you do not want to use Low Power Mode, you can turn it off in a few seconds.
The exact menu depends on your iPhone model and iOS version.
Method 1: Turn Off Low Power Mode in Settings
Follow the instructions for your device.
For iPhone 14 and earlier:
- Open Settings.
- Scroll down and tap Battery.
- Find Low Power Mode.
- Switch it off.
For iPhone 15 and later:
- Open Settings.
- Tap Battery.
- Select Power Mode.
- Turn off Low Power Mode.
After switching it off, check the battery icon at the top of your screen. It should return to its normal color.
Method 2: Turn Off Low Power Mode Using Control Center
Control Center provides quick access to commonly used settings.
- Swipe down from the top-right corner of your screen to open Control Center.
- Look for the Low Power Mode control.
- Tap it to turn the feature off.
If the control is not visible, you may need to add it to Control Center, depending on your iOS version and configuration.
You can also ask Siri to turn off Low Power Mode.
These methods allow you to remove the yellow battery icon without restarting your iPhone or changing unrelated settings.
3. What Happens When Your iPhone Battery Is Yellow?
When your battery icon turns yellow, your iPhone is using Low Power Mode to reduce energy consumption.
This can affect several features.
Reduced Background Activity
Low Power Mode limits Background App Refresh, which means apps may not update their content in the background as frequently.
You might notice that some information refreshes only after opening an app.
Lower Screen Brightness
Your display may become less bright to help conserve battery power.
If the screen seems dimmer than usual, check whether Low Power Mode is enabled before changing other display settings.
Shorter Auto-Lock Time
Auto-Lock may default to 30 seconds while Low Power Mode is active. This helps prevent your display from staying on unnecessarily.
Paused Automatic Downloads and Email Fetch
Automatic downloads and scheduled email fetching may be reduced or disabled. As a result, some emails or other content may not update until you open the relevant app or the phone leaves Low Power Mode.
Temporary Pause in iCloud Photos Syncing
iCloud Photos syncing may be temporarily paused while Low Power Mode is active. This does not necessarily mean your photos have been deleted.
Reduced Display Refresh Rate on Supported Models
On iPhone models with ProMotion displays, the refresh rate is limited to up to 60 Hz in Low Power Mode. Some animations may therefore look less smooth.
These changes are designed to save power. Your iPhone should still perform its essential functions, including calls, messages, and internet access.
4. Why Does My iPhone Battery Keep Turning Yellow?
If your iPhone battery repeatedly turns yellow, it does not automatically mean something is wrong.
Check the following possibilities.
Check Whether You Are Enabling It Accidentally
You might be turning on Low Power Mode through Control Center without noticing.
Open Settings and check its current status.
If you use shortcuts or automations, review them to see whether any are configured to enable Low Power Mode.
Check Adaptive Power Settings
On compatible iPhone models running supported software, Adaptive Power can adjust settings to help extend battery life. When enabled, it can also activate Low Power Mode automatically under supported conditions.
To check it:
- Open Settings.
- Tap Battery.
- Tap Power Mode.
- Review the Adaptive Power settings if they are available on your device.
If Low Power Mode turns on automatically, check whether Adaptive Power is enabled.
Check Your Charging Habits
Low Power Mode normally turns off automatically when your iPhone charges to 80% or higher.
If you frequently use your phone without charging it, you may find yourself enabling Low Power Mode more often.
You do not need to disable this feature permanently. It is perfectly fine to use it whenever you want to extend battery life.
Review Your Battery Usage
If your battery drains unusually quickly, open Settings and tap Battery.
Review the battery usage information to identify apps or activities that consume a lot of power.
This can help you distinguish normal battery-saving behavior from a separate battery-drain problem.
5. How to Keep Your iPhone Battery Healthy
Low Power Mode can help extend the time your iPhone runs between charges, but it does not repair a worn-out battery.
If you want to maintain good battery performance over time, follow these practical tips.
Reduce Unnecessary Screen Brightness
A very bright display can consume more energy. Use a comfortable brightness level and consider Auto-Brightness if it suits your needs.
Check Which Apps Use the Most Battery
Open Settings and tap Battery to review your usage information.
If an app consistently consumes a large amount of power in the background, review its settings and background activity.
Avoid Excessive Heat
High temperatures can negatively affect battery lifespan. Keep your iPhone away from direct sunlight and other sources of excessive heat, especially while charging.
Use Low Power Mode When Needed
You can enable Low Power Mode when you are travelling, away from a charger, or trying to make your remaining battery last longer.
There is no need to avoid this feature simply because the icon turns yellow.
Check Battery Health
On supported iPhone models, open Settings and look for Battery Health or Battery Health & Charging.
The exact menu depends on your model and software version.
If your battery capacity has significantly declined or you see a service recommendation, consider getting the battery checked by Apple or an authorized service provider.
