How to Fix iPhone 14 Battery Draining Overnight

Waking up to find your iPhone 14 nearly dead? You’re not the only one frustrated by excessive battery drain overnight. Many users face this annoying issue of seeing their iPhone battery plummet while sleeping. But don’t panic – in most cases, the overnight battery drain points to a fixable software or settings cause, not a hardware problem.

iPhone 14 Battery Draining Overnight

This article will walk you through the top techniques to diagnose and address battery drain on your resting iPhone 14. Follow our troubleshooting guides below to keep your iPhone battery charged through the night.

Unexpected battery drain while the iPhone is idle can be caused by a few common culprits. Let’s look at the main offenders and how you can stop them from ruining your overnight charge.

Common Causes of Overnight Battery Drain

Excessive battery drain while your iPhone 14 sleeps likely stems from one of these common issues:

  • Apps continuing to run in the background – Apps that don’t properly go to sleep can drain resources.
  • Old iOS software needing an update – Outdated OS lacks optimizations.
  • Location services or Bluetooth being left on – Continued use overnight drains battery.
  • Brightness settings too high – More light requires more power.
  • Certain features like Hey Siri enabled – Listening drains battery.
  • Indexing and backups running overnight – System tasks use CPU and energy.
  • Bugs introduced by new iOS updates – New software can have quirks.
  • Failing battery unable to hold full charge – Capacity naturally degrades over time.

Understanding the usual suspects behind your iPhone battery drain gives you a better chance of targeting the right fix.

Troubleshooting Steps to Fix iPhone 14 Battery Drain Overnight

Luckily, with some focused troubleshooting and tweaks, you can stop your iPhone 14’s battery from emptying overnight:

Close All Apps Before Bed

Closing out any apps still running in the background is essential to maximize your overnight battery life. Apps that remain active will continue to consume CPU power and energy.

To close your open apps:

  1. Double-click the home button to bring up your app switcher.
  2. Swipe up on the preview screenshots of any open apps to force close them.
  3. Repeat until all apps are closed and the switcher is empty.
  4. This prevents apps from running in the background overnight.

Turn Off Bluetooth and Location Services

Leaving Bluetooth and location services on while your phone is idle overnight can cause a significant battery drain. To conserve battery life, it’s recommended that you turn off these features when you’re not using them. 

You should disable these when not needed:

  1. Open Settings and tap Bluetooth.
  2. Turn off Bluetooth to disconnect accessories and peripherals.
  3. In Settings, choose Privacy, then Location Services.
  4. Turn off location access for all apps and system services.

Use Low Power Mode While Sleeping

By activating Low Power Mode, you can help conserve power during the night by limiting background activity. This is particularly useful when you’re not using your phone for extended periods of time and want to ensure that the battery lasts longer. 

To enable it:

  1. Go to Settings > Battery > Low Power Mode.
  2. Enable Low Power Mode to activate the battery-saving restrictions.
  3. Your iPhone will enable Low Power Mode automatically each night.

Adjust Screen Brightness Lower

If you find that your device’s battery is draining faster than you’d like, try reducing the brightness of the screen backlight. This can significantly improve your battery life and help you get more out of your device throughout the day. 

Before bed, you should lower the brightness:

  1. Open Control Center by swiping down from the top right.
  2. Drag the Brightness slider left to lower the brightness level.
  3. Turning down the brightness will extend the battery overnight.
  4. Enable Auto-Brightness to allow adaptive adjustments.

Update to the Latest iOS Version

Updating your iOS software is a crucial step to ensure that your device runs smoothly and efficiently. With each software update, you can expect to receive battery optimizations and bug fixes that can enhance your overall user experience. 

To update:

  1. Go to Settings > General > Software Update.
  2. Download and install the latest iOS update.
  3. Updates fix bugs and improve battery performance.

Disable Background App Refresh

“Background App Refresh” is a feature available on most smartphones that allows apps to continue accessing data and location even when they are not actively being used. This can be useful for apps that require constant updates, such as weather or news apps. However, it can also drain your battery and use up your data plan, so it is important to manage which apps are allowed to use this feature. 

To turn off:

  1. Go to Settings > General > Background App Refresh.
  2. Switch Background App Refresh to Off position.
  3. This prevents unnecessary background drain.

Turn Off Hey Siri

Enabling Hey Siri means that your phone is always actively listening for voice commands, which can consume a significant amount of battery power. This is because the microphone is constantly picking up sounds and analyzing them for potential Siri prompts. If you find that your phone’s battery life is draining faster than usual, it may be a good idea to disable Hey Siri or limit its use to conserve battery power.

Disable this feature before bed:

  1. Go to Settings > Siri & Search.
  2. Turn off Listen for “Hey Siri” to disable always listening.

Factory Reset iPhone

Performing a factory reset means restoring your device to its original settings and erasing all of your data and apps. It’s important to note that this should be done only as a last resort after exhausting all other troubleshooting options. Before proceeding, make sure to back up all your important data and files. 

To reset:

  1. Backup your iPhone data to iCloud or iTunes.
  2. Go to Settings > General > Transfer or Reset iPhone.
  3. Choose Erase All Content and Settings to wipe and restore your iPhone.

Replace Worn Out Battery

When a battery is used frequently over time, it can start to lose its ability to hold a full charge. This is known as battery degradation. It’s important to keep an eye on the battery life of your devices and replace them when necessary to ensure they continue to function properly.

Consider having Apple replace the battery if:

  1. Battery health is lower than 80% of maximum capacity.
  2. The phone shuts down prematurely even when charged.
  3. Excessive battery drain persists after troubleshooting.
  4. Replacement restores battery life and overnight charge.


  1. My iPhone 14 loses a large amount of battery life overnight while I’m sleeping. Why is it draining so fast during idle hours?

    Excessive battery drain overnight is typically caused by apps refreshing data in the background, location services running, “Hey Siri” enabled, Bluetooth/Wi-Fi left on, and notifications disrupting the idle state. Check settings to limit background activity, turn off unneeded connections and features, update iOS, and disable unnecessary notifications.

  2. I made sure no apps were running in the background, but my iPhone 14 still loses battery life overnight. What else could be the issue?

    If background app activity is already restricted, further overnight battery drain could stem from older batteries with diminished capacity, prolonged exposure to high or low temperatures, bugs in iOS, or a rogue third-party app with technical issues. Check battery health, avoid temperature extremes, update iOS, and delete problematic apps.

  3. How can I tell which app is draining my iPhone 14 battery excessively overnight?

    Go to Settings > Battery to view battery usage data. Check the list for any apps using a very high percentage of battery in the background. Social media, news, and email apps are common culprits. You can disable background activity on specific apps here.

  4. Why does my iPhone 14 still drain battery life overnight, even in Low Power Mode?

    While Low Power Mode limits background refresh and connectivity, some battery drain overnight is still normal. Make sure to disable “Hey Siri,” reduce screen brightness, turn off Wi-Fi/Bluetooth, and silence unnecessary notifications completely. Apps may still run briefly in the background.

  5. My iPhone 14 is less than a year old. Should I be concerned about its battery life declining so quickly overnight?

    Significant battery degradation resulting in a rapid overnight drain on a new iPhone 14 is not typical. Contact Apple support for potential warranty replacement of a defective battery if you’ve already tried optimizing settings. A manufacturing defect might be reducing capacity.
