Have you observed your mobile data running out sooner than you anticipated or your iPhone’s battery fading too quickly? Certain apps on your iPhone may continue to use data and power in the background even when you’re not actively using them. Excessive battery and data utilization can be caused by location tracking, background processes, automatic updates, and concealed program activities.
We’ll explain the main causes of your iPhone using data and battery in the background in this tutorial, along with—and perhaps most importantly—how to stop it.

Why your iPhone is draining battery and data in the background
Even when you’re not using your iPhone, it can still be wasting data and power. App updates, location tracking, and system services are examples of background operations that operate silently and are the source of this. You can improve settings, prolong battery life, and cut down on wasteful data usage by figuring out what’s causing this drain.

– How background activity affects battery life & data usage
Even when your screen is off, apps and system processes continue to function in the background. These activities can include:
- Fetching new emails and notifications
- Syncing data with cloud storage
- Running location services for maps and weather updates
- Downloading software updates or media content
While these functions enhance user experience, they can significantly impact battery life and consume mobile data, especially if left unchecked.
– Common causes of background battery drain
Several factors can cause excessive battery drain, including:
- Background app refresh: Apps constantly updating data in the background can drain battery and use mobile data.
- High screen brightness: Keeping your screen brightness at maximum consumes more power.
- Push notifications: Frequent updates from messaging, social media, and email apps require continuous background activity.
- Location services: GPS tracking apps running in the background can drain the battery quickly.
- Poor network signal: If your iPhone struggles to maintain a stable connection, it will use more power searching for a signal.
- Widgets and live activities: Constant updates from widgets and live tracking features consume extra battery.
– How Background App Refresh consumes data without you knowing
Background app refresh allows apps to update their content even when you’re not using them. This helps keep information up to date but can lead to unnecessary data usage.
- Social media and messaging apps constantly refresh to load new content and messages.
- Streaming services may pre-load videos or music, using mobile data in the background.
- Cloud services automatically sync photos, documents, and backups, consuming both data and battery.
To reduce this drain, you can disable Background App Refresh for specific apps by going to: Settings → General → Background App Refresh, then selecting “Wi-Fi only” or turning it off completely for certain apps.

Identifying battery- and data-draining apps
Finding the apps that use the most resources is crucial to preventing excessive data usage and battery degradation. iOS comes with built-in capabilities that let you keep an eye on data and battery usage, identify problematic apps, and change settings accordingly.
– Checking battery usage in settings (which apps use the most power?)
Your iPhone tracks battery consumption for each app, showing which ones drain the most power. To check:
- Open Settings and go to Battery.
- Scroll down to see the battery usage breakdown by app.
- View stats for the last 24 hours or last 10 days to identify trends.
- Check for apps using high battery in the background, even when not in use.
If an app consumes too much power, consider restricting its background activity, disabling push notifications, or limiting location access.
– Monitoring data usage to find hidden data-hogging apps
Apps running in the background can silently consume large amounts of mobile data. To check data usage:
- Open Settings and go to Cellular (or Mobile Data).
- Scroll down to see a list of apps and their data usage.
- Identify apps using excessive data, even when not in use.
- Disable Background App Refresh for apps that don’t need constant updates.
If you notice an app using too much data, you can disable its mobile data access by toggling it off in the Cellular settings.
– Using screen time to detect apps running in the background
Screen Time provides insights into how long each app is active, including background usage. To check:
- Open Settings and go to Screen Time.
- Tap See All Activity under the Daily or Weekly Report.
- Look for apps with unusually high usage times.
- Identify apps running in the background longer than expected.
If an app has excessive background activity, consider adjusting its notification settings, reducing auto-refresh frequency, or limiting its access to location services.

Preventing background apps from using too much data and battery
Unknown to you, background apps can use up mobile data and sap your iPhone’s battery. You can enhance your phone’s performance and battery life by tweaking specific settings to avoid needless power and data usage. The main strategies for preventing background apps from using your resources are listed below.

– How to disable Background App Refresh for specific apps
Background App Refresh allows apps to update content in the background, even when you’re not actively using them. While this feature can be useful for messaging apps and news updates, it can also drain battery life and use up mobile data.
Steps to Disable Background App Refresh:
Go to Settings → General → Background App Refresh. Tap Background App Refresh at the top and choose:
- Wi-Fi & Cellular Data – Allows apps to refresh using both.
- Wi-Fi – Only refreshes apps when connected to Wi-Fi.
- Off – Completely disables background refreshing.
- Scroll through the list and toggle off apps that don’t need background refresh.
– Turning off automatic app updates & downloads over cellular
By default, iPhones automatically update apps and download purchases made on other Apple devices. This can consume a significant amount of battery and data, especially for large app updates.
Steps to Disable Automatic Updates & Downloads Over Cellular:
- Open Settings and go to App Store.
- Under Automatic Downloads, turn off App Updates and App Downloads.
- Under Cellular Data, turn off Automatic Downloads to prevent updates over mobile data.
- If needed, enable Ask If Over 200MB to get a prompt before downloading large updates.
– Restricting location services to save battery & data
Many apps use location tracking even when they don’t need to, which drains battery and consumes data. You can manage location permissions for individual apps to reduce unnecessary background activity.
Steps to restrict location services:
Open Settings and go to Privacy & Security → Location Services.
- Never – Completely blocks location access.
- Ask Next Time or When I Share – Prompts you before using location.
- While Using the App – Allows location access only when the app is open.
- Always – Allows apps to track location even in the background (not recommended).
Disable Precise Location for apps that don’t require exact tracking, like weather or shopping apps.
– Managing push notifications to reduce unnecessary activity
Push notifications from social media, emails, and other apps can wake up your phone frequently, consuming battery and data. Managing these notifications can reduce unnecessary background activity.
Steps to manage push notifications:
Open Settings and go to Notifications.
