ByFor iPhone users, battery life is one of the most critical aspects. It often happens that the phone begins to discharge rapidly, even during normal usage. In such situations, the culprit is often an app consuming excessive battery power while running in the background. The iPhone features a useful tool that allows us to easily identify exactly which app is consuming the most battery power.
By identifying these battery-hungry apps promptly, we can significantly improve battery backup and enhance the phone’s overall performance. In this comprehensive guide, we will explore in detail how to check app battery usage on an iPhone, how to interpret the battery usage report, and which strategies are most effective for reducing battery consumption.
What is the Battery Usage Feature on iPhone?
The Battery Usage feature built into the iPhone provides a detailed record of the battery power consumed by each app. This information reveals:
Which app is consuming the most battery power
Which apps are currently active in the background
Which apps consumed the most battery while the screen was on
The impact of background activity on battery life
Battery usage data for the last 24 hours and the last 10 days
With the help of this feature, we can make informed decisions based on actual data rather than relying on guesswork.
How to View Apps by Battery Usage on iPhone
If you want to find out which app is consuming the most battery power on your iPhone, follow the steps outlined below.
Step 1: Open the Settings App
First, open the Settings app on your iPhone. This serves as the main system control panel where all essential settings and configurations are located.
Step 2: Go to the Battery Option
Scroll down on the Settings screen and tap on the Battery option.
Upon entering the Battery section, you will see various details related to the battery, such as:
Battery Percentage
Low Power Mode
Charging Status
Battery Usage Graph
This is where the complete report regarding app battery consumption is located.
Step 3: Allow Battery Activity to Load
Wait a few seconds after opening the Battery section.
Your iPhone processes data in the background and then displays the Battery Activity and App Usage reports. If the data does not appear immediately, wait for a short while.
Step 4: View the List of Apps’ Battery Usage
As you scroll down the screen, you will see a list of all your installed apps.
Next to each app, the percentage of battery usage is displayed.
Example:
Instagram – 25%
YouTube – 18%
WhatsApp – 12%
Safari – 8%
This percentage indicates how much that specific app contributed to the total battery consumption.
If an app shows an unusually high percentage, it may be the primary cause of the battery drain.
How to View “Last 24 Hours” and “Last 10 Days” Data
The iPhone displays battery usage data across two distinct time periods.
Last 24 Hours
This option shows battery data for the past 24 hours.
It helps us identify:
Which apps have been used most recently
Which app caused a sudden battery drain
Which app is currently impacting the battery status
Last 10 Days
This option provides a long-term analysis.
It is useful if:
The battery has been performing poorly over an extended period
An app is causing a gradual depletion of the battery
You wish to understand your usage patterns
By reviewing the 10-day data, you can draw more accurate conclusions.
How to Interpret the Battery Graph
The Battery section also displays a graph that illustrates battery usage and charging history.
This graph is divided into two main parts.

Battery Level Graph
This graph indicates:
When the battery level dropped
When it was charged
The rate at which it discharged
If the graph drops sharply and suddenly, it implies that a specific app or process is consuming excessive battery power.
Activity Graph
This graph displays app usage duration.
It consists of two key components:
Screen On
The period when the screen was active and the app was being used.
Screen Off
The period when the screen was off, yet the app continued to run in the background.
If an app shows high Screen Off Activity, it indicates that it is consuming battery power while running in the background.
What is the “Show Activity” Option in Battery Usage?
Within the Battery list, there is a significant option: Show Activity.
By default, usage is displayed as a percentage; however, tapping on “Show Activity” provides time-based data.
This view reveals:
How many minutes or hours the app was active
The duration of “Screen On” usage
The extent of background activity
This feature makes battery analysis much clearer and more insightful.
Which Apps Consume the Most Battery Power?
For most iPhone users, certain apps typically consume a disproportionately high amount of battery power.
These include:
Social Media Apps
Snapchat
X
These apps constantly utilize the internet, camera, and notifications.
Video Streaming Apps
YouTube
Netflix
Other OTT Platforms
Video streaming places a heavy demand on the screen, processor, and internet connection.
Navigation Apps
Maps
GPS-based apps
Location tracking leads to higher battery consumption.
Gaming Apps
High-graphics games:
GPU
CPU
Display Brightness
utilize these extensively, causing the battery to drain rapidly.
How Background Activity Affects Battery Life
Many apps remain active in the background even when they appear to be closed.
Examples:
Email Sync
Location Updates
App Refresh
Notifications
This is why the battery continues to drain even when the phone is not in use.
If you see Background Activity listed beneath an app in the Battery report, it indicates that the app is consuming resources in the background.

How to Control Apps That Drain Battery
If an app is consuming excessive battery power, it can be managed.
Turn Off Background App Refresh
Settings → General → Background App Refresh
Navigate here to disable this feature for unnecessary apps.
This reduces background battery usage.
Limit Location Access
Settings → Privacy & Security → Location Services
For apps, select options such as:
Never
While Using App
Granting “Always” location permission can cause the battery to drain rapidly.
Reduce Push Notifications
Constant notifications consume:
Internet data
Screen time
Processing power
Disabling unnecessary notifications is a helpful practice.
Enable Low Power Mode
Settings → Battery → Low Power Mode
This feature saves battery by limiting:
Background Activity
Mail Fetch
Visual Effects
Why Checking Battery Health Is Also Important
Often, the issue lies not with the apps but with the condition of the battery itself.
To check this, go to:
Settings → Battery → Battery Health & Charging
Here, you will find:
Maximum Capacity
If this figure is:
100–90% = Excellent
89–80% = Normal
Less than 80% = Battery is weak
You may need to replace the battery.
Benefits of Monitoring iPhone Battery Usage
Regularly checking battery usage offers numerous advantages.
Helps Identify the Cause of Rapid Battery Drain
Eliminates the need for guesswork.
Improves Phone Performance
Managing resource-intensive apps ensures the system runs more smoothly.
Reduces Charging Frequency
Extends battery backup.
Prolongs Battery Lifespan
Reducing unnecessary consumption has a direct positive impact on battery health.
Conclusion
Viewing Apps By Battery Usage on an iPhone is an extremely useful feature that simplifies battery management. By navigating to the Battery section within Settings, we can easily identify which apps are consuming the most power. Features such as Last 24 Hours, Last 10 Days, Show Activity, Battery Graph, and Background Activity provide deep insights into battery behavior.
