User Concern

“Recently I've updated my iPhone to iOS 18 and I noticed that the device battery is draining too fast all of a sudden. My battery health is 100%. How can I fix this issue?”

Have you noticed that your iPhone battery is draining too fast all of a sudden and not holding a charge for long? This is a common problem that many iOS users experience and it can happen without any obvious reason.

In this guide, we will explain why your iPhone battery is draining too fast all of a sudden and how to fix the issue. Also, you can learn some tips to save battery life on your iPhone. Let's check out.

Why is My iPhone Battery All Of A Sudden Draining So Fast?

It's not normal for the iPhone battery to drop suddenly. Let's look at some key factors that lead to this problem:

• Inappropriate Settings: Settings related to location services, display, and notifications can consume the battery power, leading to the repaid battery draining.
• Background Apps: Apps running in the background require resources. If you don't close an app after using it, it will continue to consume battery power.
• Major iOS Update: A new iOS update like the recent iOS 18 update brings many big changes to your iPhone features, which can make the device drain battery fast.
• iPhone Battery Health: If your iPhone's battery capacity is low, less than 80%, the battery may drain very quickly.

How Do I Stop My iPhone Battery from Draining So Fast?

The following are just some of the things you can do when your iPhone's battery is suddenly draining too fast:

Check iPhone Battery Usage

If you find your iPhone battery draining fast all of a sudden, you should examine all the apps and find out which apps eat your iPhone battery the most.

Go to Settings > Battery > Battery Usage; you can see the battery percentage used by each app. If you find any app that you seldom use is eating your battery, you can try to remove it.

Remove Unnecessary Widgets

As helpful as they can be, widgets can be serious battery drainers since they have to refresh every few minutes to present the most accurate information. To remove some of the widgets you don't need, follow these simple steps:

• Press and hold on to any widget you would like to remove.
• Tap on the Remove Widget that appears and then tap Remove to confirm.

Turn Off Background App Refresh

As the name suggests, this feature allows your apps to continually refresh in the background even when you are not using them. The problem is that it can really drain the battery. To turn it off, follow these simple steps:

• Go to Settings > General on your iPhone.
• Tap on Background App Refresh and turn it off.

Turn Off Wi-Fi & Bluetooth

Wi-Fi can also be a battery drainer, and when you're not using it, it may be a good idea to turn it off. Just go to Settings >WiFi and turn it off.

Bluetooth can also cause your iPhone's battery to drain faster than necessary. Turning Bluetooth off is a good idea, especially when you're not using it. Here's how: Go to Settings > Bluetooth and turn it off.

Turn Off Location Services

Not every app on your iPhone needs to use location services all the time. Location services will run in the background and consume significant battery power, even when you're not using the app.

To fix your iPhone battery draining fast all of a sudden, go to Settings > Privacy & Security > Location Sevices. Here, you can either turn off location services entirely or change the location access settings for specific apps.

Turn Off iPhone Notifications

Whenever we receive messages from apps, notifications will appear on the screen and wake the iPhone up, which can significantly drain battery life. Disabling the notifications for unnecessary apps can help save a lot of battery life. Here's how to do it:

• Open Settings on your iPhone or iPad and tap Notifications.
• Select the app you want to disable notifications for, then turn off the toggle.

Turn Off iPhone Once a Week

Another neat solution you can try is turning off your iPhone once a week. This trick is known to resolve battery issues, especially if you've noticed that your battery has been draining for some time. Powering down your iPhone can help eliminate crashing apps and any technical issues that can pile up over time.

Turn On Reduce Motion

Newer iPhones use the parallax effect to create a sense of depth and movement on the Home screen and elsewhere. While this feature adds visual appeal, it consumes more battery power. To turn off the parallax effect and save battery:

• Go to Settings > General and then tap Accessibility.
• Tap Motion > Reduce Motion and turn the switch to On.

• Turn On Airplane Mode: If you are in a poor signal area, you’d better turn on Airplane Mode. This will prevent your iPhone from constantly searching for wifi signals.
