If you are facing battery drain on your iPhone with the latest update, here is how to remedy the issue.
What Is The iOS 18.3 Battery Drain Issue?

Apple has yet to issue a fix for the battery drain issue in iOS 18.3, leading many people to suspect Apple Intelligence could be the culprit. A YouTube channel, iAppleBytes, recently performed a battery test. It showed that the Apple iPhone 15 deteriorated while the Apple iPhone XR saw improvements.
Possible Reasons For iOS 18.3 Battery Drain Issue
Before we take a look at how to fix the battery drain in iOS 18.3, here are some of the possible reasons behind the issue:
- Apple Intelligence: Apple Intelligence is likely to be one of the major reasons behind battery drain. Given its resource-intensive nature, the feature consumes a lot of power. Many users have also reported a bug where Apple Intelligence is stuck in “downloading”. This results in an indefinitely long rapid battery drain.
- Lack of optimization: Another reason for battery drain in iOS 18.3 could be the lack of optimization. Given its recent update, there is a possibility that it might take a while to calibrate once background tasks are over.
- Background services: Services running in the background can drain your battery life. If an app continuously runs in the background, it will consume a lot of battery.
- Increased CPU Usage: Some features like Apple Intelligence and background apps require a lot of processing power. This can result in your iPhone heating up due to more load on the CPU. It ultimately affects your battery as your processor sips juice in the background.

How To Fix The Battery Drain In iOS 18.3
1. Disable Apple Intelligence
Disabling Apple Intelligence is the first step in preventing battery drain in iOS 18.3. It was also responsible for the battery drain issue in the previous update, iOS 18.2. You can try disabling the feature to check whether there is any improvement in battery life. If your iPhone does not support Apple Intelligence, we suggest moving to the next step.
2. Use Low Power Mode
Low Power Mode is another method to remedy the battery drain issue. It will help your iPhone last longer by preventing tasks from running in the background. However, you will need to deal with the following effects of Low Power Mode:
- Disables 5G connectivity on Apple iPhone 12 and Apple iPhone 13
- Reduces Auto-Lock to 30 second
- Dims display brightness
- Disables Promotion, limiting refresh rate to 60Hz
- Disables visual effects
- Refreshing of email and background apps
- No automatic download
- Backing up of photos to iCloud

3. Change These Settings
If you don’t want to use Low Power mode since it affects background tasks, you can tweak some settings. By changing the following settings, you can negate the effect of battery drain in iOS 18.3:
- Disable ProMotion: Reducing your refresh rate to 60Hz can help you preserve battery life
- Turn Off Location Services: Many apps require access to your location and, hence, consume your battery in the background. Disabling location services can help prevent battery drain.
- Enable Dark Mode: Using a dark mode on your iPhone can prolong its battery life, especially if you have an iPhone with an OLED screen.
- Turn Off Wi-Fi Assist: The Wi-Fi assist feature turns on cellular data if you are connected to a weak Wi-Fi network. You can turn off this feature in Settings->Cellular.
- Disable Auto Brightness: The auto-brightness feature automatically adjusts the brightness on your iPhone. However, it can also consume a lot of battery power, so disabling the feature and manually setting the brightness can fix this.
4. Update Your Apps
Sometimes, the problem lies in a specific app that consumes more power than is required. To find the culprit, you can check Battery Usage by app in Settings->Battery and Activity by app. Since most people don’t update their apps, they miss important bug fixes. Make sure to update all your apps to the latest version from the App Store.

5. Check Battery Health
Last but not least, your battery might have degraded. You can check your battery health by heading to Settings->Battery->Battery and charging. If your battery is below 80 per cent healthy, you might need to replace it. A degraded battery will not offer the same backup as a brand-new battery. Moreover, the battery drain issue in iOS 18.3 will further aggravate the issue.
Summing It Up
Before Apple officially releases an update to fix battery drain in iOS 18.3, you can try the troubleshooting methods above. If none of the methods work, you can try resetting your iPhone or carrying a power bank with you. While not a permanent fix, it should negate the issue until Apple addresses it.
