1. Turn off Wi-Fi and Mobile Data

Even when not in use, the network connections put a considerable amount of strain on the device to get the best signal strength. This is a massive cause of battery drainage. Hence, it’s essential to turn off Wi-Fi and Mobile Data before you go to sleep.

  1. Open the Control Center.
  2. Tap the Wi-Fi and Data icon to disable them.

    Use control centre in iPhone

Alternatively, you can turn off Wi-Fi and your cellular data connection from your iPhone’s Settings.

  • Navigate to Settings Wi-Fi → Toggle off Wi-Fi.

    Access Wi-Fi in settings, toggle off Wi-Fi in settings

  • Go back to Settings Cellular → Toggle off Cellular Data.

    tap Cellular, toggle of Cellular Data in Settings

Tip: Disable Personal Hotspot if you don’t need it, as sharing your cellular data heats up your iPhone. Thus, the battery is consumed much faster.

2. Turn Bluetooth off on iPhone

Another reason your iPhone battery drains so fast overnight is keeping Bluetooth enabled. Bluetooth constantly searches for a nearby device to quickly connect. So, it shortens the battery life of your iPhone.

  1. Go to Settings Bluetooth.
  2. Toggle off Bluetooth → Hit Turn Off if prompted.

    Access bluetooth, hit turn off when prompted in settings

You can do the same via the control center on your iPhone.

3. Enable Airplane mode

Airplane mode cuts off all the wireless connections on your iPhone. So, you don’t need to turn off Wi-Fi or Bluetooth individually. Plus, it saves significant power and extends the battery health.

  1. Open Control Center.
  2. Tap the Airplane icon.

    Refresh cellular network using Airplane mode

Remember to turn it off in the morning to continue using your cellular data or Wi-Fi.

4. Adjust brightness settings on iPhone

By default, auto-brightness is enabled on the iPhone to adapt ambient lighting. However, if you set a higher brightness level, your iPhone must produce more light. So, adjust the brightness settings to the lowest comfortable level to optimize your battery performance on your iPhone.

  1. Launch Settings → Access Display & Brightness.
  2. Reduce the brightness bar to your comfort.
  3. Additionally, toggle on True Tone.
    This will adjust the display colors according to the ambiance of your surroundings.

    Access Display & Brightness, adjust the slider, enable true tone in settings

Now, whenever your iPhone wakes up at night, its display will be dimmer, saving battery life.

5. Use Night Shift mode

Activating the night shift mode can do the trick if your iPhone battery drains overnight. This feature automatically shifts the colors of your iPhone’s display to eliminate the blue light during specific hours of the day, including nighttime.

  1. Launch Settings → Go to Display & Brightness.
  2. Choose Night Shift.
  3. Select a schedule for how long it would be active each day and adjust the color temperature slider.

    Go to Display & Brightness, choose the Night Shift option, make changes in settings

By reducing the exposure to blue light, you not only extend the battery life of your device but develop a healthy sleeping atmosphere for you as well.

6. Enable Low Power mode on iPhone

If you are not switching off your iPhone for the night, consider enabling Low Power mode. It restricts the background activities and disables power-hungry apps to optimize the battery life.

  1. Open Settings → Navigate to Battery.
  2. Toggle on Low Power Mode.
  3. Hit Continue if prompted.

    Enable Low Power Mode on iPhone

7. Turn off the Background App Refresh

The Background App Refresh feature is set to stimulate the content of your device when Wi-Fi or mobile data is activated. Although it is an excellent feature, it can be one of the primary reasons for battery drainage on your iPhone. Hence, I advise disabling this feature through the night.

  1. Open Settings app.
  2. Access General Background App Refresh.

    Tap general, background app refresh in settings app

  3. Select Background App Refresh → Choose Off to disable it.

    Open the Background App Refresh option and choose off to disable it

Tip: Close all the apps running in the background before going to sleep to ensure your iPhone is idle overnight.

8. Disable Location Services on iPhone

Location Services in your iPhone enhance your overall experience. However, as a significant drawback, this feature consumes a considerable chunk of your battery. Therefore, if you leave it running overnight, you’ll be out of juice by the morning.

By disabling Location Services on your iPhone, you can extend the overall life of your battery and prevent any future drainage issues. However, I do not recommend this alteration for a few applications that run by collecting geographical data.

9. Reduce White Point

  1. Navigate to the SettingsAccessibility.
  2. Choose Display & Text Size.
  3. Now, turn on Reduce White Point and shift the slider to 100%.

    Display & Text Size option. Now, toggle on the Reduce White Point option and shift the slider to 100% in settings

By minimizing the intensity of bright colors on your iPhone at night, you can significantly reduce battery consumption. Also, I suggest using the system-wide Dark mode on iPhone to lessen the white screens.

10. Update iOS apps regularly

If any app is experiencing a major bug, it may drain the iPhone battery fast. To solve the performance issue, the publisher may release an update. Therefore, ensure all the apps on your device are up to date. Keep an eye out for available upgrades to get you going.

11. Update iOS software

Various factors can contribute to overnight battery drain issues even when the device is unused. However, one practical solution to get rid of this problem is by updating the iOS software.

It is common for Apple to release firmware updates equipped with bug fixes and performance improvements that prolong the lifespan of the battery as well. As a result, developing a habit of regularly updating your device can be helpful in numerous ways.

12. Remove unnecessary apps from iPhone

The most common cause of overnight battery drainage of your iPhone could be unnecessary apps. Hence, it’s vital to get rid of the apps that you do not use anymore.

These apps tend to consume power even when the device is not in use and keep on impacting the battery life. However, if you’re unaware of the applications that might be causing the most impact on your device, the next tip will get you started.

13. Check battery usage on iPhone

If you’re still unable to rectify the core of the problem causing overnight battery drainage in your iPhone, it’s time to level up the game. An ideal way to deal with this issue is to monitor the battery usage of your device.

  1. Open Settings → Navigate to Battery.
  2. Check the active apps on your device.

    Access battery, access the active apps on your device in settings app

Now, adjust the apps that are using the most battery accordingly. For example, if an app consumes too much power, you must manually close it or disable background refresh for that app. If there is any unnecessary app spending battery, uninstall them.

14. Reset your iPhone

Last but not least, for those who are still struggling with losing the power of their device every night, resetting your iPhone is a tried and tested method that could solve this issue. As you go through this technique, every software glitch affecting the battery performance will be rectified. 

15. Enroll in the battery replacement program

Check the Battery Health and charge cycle count on your iPhone. Detroit batteries could not hold the charge for much longer. If this is the case, opt for Apple’s battery repair service. It involves a professional technician who will run necessary tests on your device to determine whether your battery needs to be replaced.

If you need a battery replacement, you must do that with no delay. Once your battery is replaced with a new one, it could take up to three charging cycles to reach optimal performance again.

It might be pretty unfortunate if you cannot identify and cure the battery drainage problem on your own. However, do not frown, as Apple is always available for rescue.

Contact Apple support for further assistance in diagnosing the problem you cannot rectify. Their professionals will suggest necessary measures to ensure that your iPhone lasts throughout the day without any hiccups or interruptions.
