How to Fix an iPhone Battery That Is Fully Drain Overnight?


If you've found your iPhone battery fully drained overnight, you know how frustrating it can be. Not only does it mean you can't use your phone, but you also have to recharge it, which can take a while.

Fortunately, there are some things you can work out to fix an iPhone battery that is fully drained overnight.

Wi-Fi and Mobile Data on iPhone

Your iPhone’s battery is designed to last through the day with regular use. But if you find that your iPhone battery is draining much faster than usual, it could be because you’re using certain features that are eating up power. One such feature is Wi-Fi. 

If you have Wi-Fi turned on and your iPhone constantly searches for a connection, it will use more battery power. This is why one way to help conserve your iPhone’s battery power is to turn off Wi-Fi and mobile data when they’re not in use.

To turn off Wi-Fi, go to Settings > Wi-Fi and toggle the Wi-Fi switch to the Off position. Similarly, to turn off mobile data, go to Settings > Cellular and toggle the Cellular Data switch to the Off position.

Deactivate Bluetooth

One of the most prevalent causes of an iPhone battery dying overnight is Bluetooth. If you’re not using Bluetooth, turn it off in your settings.

To turn off Bluetooth, go to Settings -> Bluetooth and switch to the Off position.

If you’re still going through problems with your iPhone battery dying overnight, it’s a good idea to consult with an Apple Store or Authorised Apple Service Provider. They can run diagnostics and help you determine if there’s a hardware issue with your battery or something else.

Brightness Settings

If your screen is set to the highest brightness setting, it will use more power and drain your battery more quickly. 

To fix this, simply adjust your screen brightness to a lower setting. You can try this in the Settings app under Display & Brightness.

Low Power Mode

One of the adequate solutions is to enable Low Power Mode. This setting helps to extend the battery life by reducing power consumption. It can be activated by heading to Settings > Battery > Low Power Mode. 

Once Low Power Mode is enabled, the iPhone will automatically take steps to reduce power consumption. For example, it may dim the screen or disable certain features. As a result, the battery will last later between charges.

Unnecessary Apps

If you have apps that you don't use regularly or are draining your battery even when you're not using them, getting rid of them can help improve your battery life. You can also try turning off features like background refresh and push notifications, which can also help conserve power. 

Update Apps and Sofware

Developers frequently release updates that include bug fixes and performance improvements, so it's always a good idea to ensure you're using the latest version. See if all of your apps and software are up to date. Outdated apps can sometimes cause unexpected battery drains. 

To update your apps, simply open the App Store and tap on the "Updates" tab. For your software, go to Settings > General > Software Update. 

Battery Replacement

Another way to solve your problem is through iPhone battery replacement. Replacing the battery yourself is cheaper and doesn't require making an appointment or taking time out of your day to drive to the store.


If your iPhone battery is draining overnight, don't worry. Simply follow things you can do to fix the issue and make sure your phone stays charged all day long. Try these tips, and your iPhone will be good as new in no time!
