Iphone Battery Drain

One major challenge many people have with their iPhones is that it doesn’t come with a battery that lasts as long as they would love. Imagine having such battery drain significantly overnight; it can be very frustrating. But what can drain your iPhone battery overnight?

Quick Answer

Leaving your data, Bluetooth, and Wi-Fi on overnight can drain your iPhone battery. Also, automatically refreshing apps in the background and those constantly sending notifications can contribute to your battery draining. Similarly, location service or syncing files to iCloud can cause your battery to drain. 

Suppose your battery was to drain by 5% or 10% overnight; that is still within an acceptable range. But having the battery drain by 50% or more is outrageous and requires you to check your iPhone to confirm if there is an underlying fault.

This article will focus on tips and tricks you can try to troubleshoot your battery draining overnight. 

How To Fix Your iPhone Battery When It Is Draining Overnight

Before you rule out that your iPhone battery is faulty, you should try a few tricks to fix it first. There are several settings on your iPhone that, if enabled, can cause it to drain your battery fast. So, it would be best if you tried disabling those settings and then charging your iPhone again. If it drains fast after turning off these settings, then it is most likely that your iPhone battery is faulty. 

Below are a few troubleshooting tips and tricks you can try out. 

Method #1: Turn Off Mobile Data and Wi-Fi 

Mobile data and Wi-Fi connections drain your smartphone battery faster than you think. If you can choose whether to use mobile data or Wi-Fi, use Wi-Fi as it is more power efficient. Also, when you are not using the internet, normalize turning off your mobile data and Wi-Fi to preserve your iPhone’s battery. 

Here’s how to conserve your iPhone’s battery by turning off data and Wi-Fi.

  • You can turn on Airplane Mode to disable both mobile data and Wi-Fi. Note that turning on Airplane Mode turns off your mobile carrier, meaning you wouldn’t be able to make calls or receive calls.
  • You can also go to the Settings app and click “Wi-Fi” to turn off the Wi-Fi.
  • You can go to the Settings app, click “Cellular Data”, then turn off the cellular data.  

Method #2: Turn Off Bluetooth 

Listening to music or a podcast on your iPhone via Bluetooth headphones all night can also drain your battery. While it may not drain your battery as much as some other things, it does cause you to lose a few percentages from your battery. So, disconnect any Bluetooth speaker, headphones, or Apple Watch from your iPhone when not in use. 

Here’s how to conserve your battery by turning off Bluetooth.

  1. On your iPhone’s home screen, tap the Settings app.
  2. In the Settings menu, tap the “Bluetooth” option, then toggle off the switch.
  3. You can also turn off Bluetooth from the Control Center by swiping up if you’re using an iPhone with a home button or swiping down from the top-right corner if you’re using a newer model. 

Method #3: Enable Low Power Mode  

The Low Power Mode is a feature Apple introduced to its iPhones and iPad sometime in 2015. It was introduced to all devices running iOS 9 or later. With this feature, you can gain additional hours of battery life by reducing your iPhone performance. 

Features such as auto sync, auto download, screen brightness, and so on will be disabled when Low Power Mode is active.

  4. You can use this same method to turn on Low Power Mode on iPadOS 14 and later.

Method #4: Turn Off the Background App Refresh 

Most of the apps on the iPhone refresh themselves automatically. And when these apps carry out processes in the background of your device, they drain your battery. However, you can stop this by turning off the background app refresh. 

Here’s how to turn off background app refresh.

  1. On your iPhone’s home screen, tap the Settings app.

When your iPhone’s GPS and location service is on, it drains your battery fast. Several apps on your iPhone can use the feature, such as WhatsApp, Skype, Facebook, etc. Once you permit these apps to use the location service, they will do so continually, which drains your battery. So, you should turn off your location’s service to conserve your battery. 

Here’s how to turn off your location service to conserve your iPhone battery.

  1. On your iPhone’s home screen, tap the Settings app.
  2. In the Settings app menu, tap the “Privacy” option.
