Why is my iPhone battery draining so fast after iOS update

Seeing your iPhone battery plummet after an iOS update is a common, and frustrating, experience. The most direct answer to "Why is my iPhone battery draining so fast after iOS update" is that updates trigger a lot of background activity like re-indexing files, optimizing the system, and recalibrating battery stats. But don't worry, in most cases, it's temporary. This article breaks down the reasons and offers solutions to get your iPhone's battery life back on track.

Understanding iOS Updates and Battery Drain

When you update your iPhone's operating system, it's not just adding new features and security patches. It's a complete overhaul. This process can cause your iPhone to work harder than usual for a period, thus consuming more battery. But why does this happen exactly?

• Re-indexing: After an update, your iPhone re-indexes all your files, photos, and data so Spotlight search can function efficiently. This process can take a significant amount of processing power.
• App Optimization: Apps need to be optimized for the new iOS version. Some apps may run less efficiently until developers release updates, causing them to consume more battery.
• Feature Introduction: New features introduced in the update might be running in the background, even if you're not actively using them. Location services, enhanced graphics, or new communication protocols can all contribute to battery drain.
• Data Migration: The iPhone migrates data to accommodate new system structures and formats, leading to higher resource usage.

Troubleshooting Steps: How to Fix iPhone Battery Drain After iOS Update

Here are some steps you can take to address your iphone battery draining quickly after update:

1. Give It Time

As mentioned earlier, it's essential to give your iPhone a few days after the update. The initial battery drain is often temporary as the system settles down. Let your iPhone complete its background tasks before taking drastic measures.

2. Restart Your iPhone

A simple restart can often resolve temporary glitches and processes that are hogging battery life. Here's how to do it:

• iPhone X and later: Press and hold either volume button and the side button until the power-off slider appears. Drag the slider, then wait 30 seconds for your device to turn off. To turn your device back on, press and hold the side button until you see the Apple logo.
• iPhone SE (2nd generation), 8, 7, or 6: Press and hold the side button until the power-off slider appears. Drag the slider, then wait 30 seconds for your device to turn off. To turn your device back on, press and hold the side button until you see the Apple logo.
• iPhone SE (1st generation), 5, or earlier: Press and hold the top button until the power-off slider appears. Drag the slider, then wait 30 seconds for your device to turn off. To turn your device back on, press and hold the top button until you see the Apple logo.

3. Check Battery Usage

iOS provides a detailed breakdown of battery usage by app. To access it:

1. Go to Settings > Battery.
2. Under Battery Usage by App, you'll see a list of apps and the percentage of battery they've consumed.

Identify apps that are using an unexpectedly high amount of battery and consider updating them, reinstalling them, or limiting their background activity.

4. Manage Background App Refresh

Background App Refresh allows apps to update their content even when you're not actively using them. While convenient, it can significantly impact battery life. To manage it:

1. Go to Settings > General > Background App Refresh.
2. You can either turn off Background App Refresh entirely or selectively disable it for specific apps.

5. Adjust Location Services

Apps that constantly track your location can drain your battery. Review your Location Services settings:

1. Go to Settings > Privacy > Location Services.
2. For each app, you can choose:
   • Never: The app never has access to your location.
   • While Using the App: The app only has access to your location when it's open and visible on the screen.
   • Always: The app has access to your location at all times, even in the background.

Select "While Using the App" or "Never" for apps that don't absolutely need constant location access.

6. Disable Push Notifications

Push notifications light up your screen and trigger activity every time you receive one. Disabling unnecessary notifications can save battery life. To manage notifications:

1. Go to Settings > Notifications.
2. For each app, you can customize the notification settings, including turning them off entirely.

7. Check Your Battery Health

Over time, iPhone batteries degrade and hold less charge. You can check your battery health in Settings:

1. Go to Settings > Battery > Battery Health.
2. Maximum Capacity indicates the battery's capacity relative to when it was new. If this number is significantly low (e.g., below 80%), it might be time to consider a battery replacement.

8. Software Update

Make sure that you always have the last version of the iOS because new versions optimize your software and have fix for potential bugs

1. Go to Settings > General > Software Update.

9. Reset All Settings

If all else fails, consider resetting all settings. This will revert all your settings to their defaults, but it won't erase your data. To do this:

1. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.

You'll need to reconfigure your settings afterward, but this can often resolve deeply embedded software issues.

Why is My iPhone Battery Draining Overnight iOS?

Waking up to a nearly drained iPhone battery is incredibly frustrating. If your iPhone battery draining overnight iOS, here's what to investigate:

• Background Activity: Even when you're not actively using your iPhone, apps can continue to run in the background, consuming battery. Follow the steps above to manage Background App Refresh and Location Services.
• Push Notifications: Notifications can wake up your iPhone throughout the night, especially if you receive a lot of them. Consider enabling Do Not Disturb while you sleep.
• Email Fetch: If you have email accounts set to "Fetch" new data frequently, your iPhone will constantly check for new emails, even overnight. Change the settings to "Manual" or increase the fetch interval.
• Wi-Fi and Bluetooth: Leaving Wi-Fi and Bluetooth enabled overnight can drain your battery as your iPhone continues to search for networks and devices. Turn them off if you don't need them.
• iCloud Backup: If your iPhone is set to automatically back up to iCloud overnight, it can consume a significant amount of battery, especially if you have a large amount of data to back up. Consider changing the backup schedule to a time when you're actively using your iPhone.

Common Mistakes to Avoid

• Closing Apps Manually: Force-closing apps doesn't necessarily save battery life. iOS is designed to efficiently manage apps in the background. Force-closing apps actually requires more energy to relaunch them.
• Using Non-Apple Chargers: Uncertified chargers can damage your battery and reduce its lifespan. Always use Apple-certified chargers.
• Extreme Temperatures: Exposing your iPhone to extreme temperatures (both hot and cold) can negatively impact battery performance. Avoid leaving your iPhone in direct sunlight or in a cold car.

Additional Insights

Beyond the troubleshooting steps above, consider these additional insights:

• Dark Mode: Enabling Dark Mode can save battery life on iPhones with OLED displays (iPhone X and later).
• Low Power Mode: Use Low Power Mode when your battery is running low. This reduces background activity and visual effects.
• Software Updates: Keep your iPhone's software up to date. Apple often releases updates that include battery optimizations.
