Troubleshooting iOS 17 Battery Drain - Fix and Tips

Part 1: The Impact of Updating to iOS 17/18/26 on iPhone’s Battery Life

iOS 17/18/26 is Apple’s latest software update, introducing enhanced features like smarter notifications, better privacy controls, and improved app functionality. While these upgrades aim to elevate the user experience, early adopters of the iOS 17/18/26 beta have reported unexpected side effects—most notably, iOS 17/18/26 battery drain.

While these features are cool, they can sometimes use up more battery power. On the positive side, the impact of updating to iOS 17/18/26 on iPhone’s battery life can include:

• Battery Gets Better

Usually, Apple works to make your battery last longer with each update. So, after updating to iOS 17/18/26, your iPhone might need to be charged less often.

• Apps Behave Better

Sometimes, apps running in the background can use up your battery. With the update, your iPhone might do a better job of controlling these apps, which could help your battery last longer.

Though, there are also not-so-good impacts:

It’s common to notice iOS 17/18/26 battery drain immediately after installing the update. This early battery drop isn’t always a sign of a long-term issue—in most cases, it’s part of the normal post-update behavior. When a major iOS update like iOS 17/18/26 is installed, your iPhone performs several background tasks such as reindexing files, updating system settings, and optimizing apps for the new software. These processes can temporarily increase CPU usage and power consumption.

If you're using an older iPhone model, the iOS 17/18/26 update may place extra demands on your device's hardware. Since newer iOS versions are optimized for the latest chipsets and features, older devices may struggle to keep up—resulting in iOS 17/18/26 battery drain and reduced overall performance.

If you're upgrading from iOS 16 or an earlier version, you may notice a change in battery performance after installing iOS 17/18/26. For some users, battery life remains stable. However, many others have reported iOS 17/18/26 battery drain happening more noticeably, especially in the first few days after the update. While some of this is expected as the system settles in, ongoing battery drain could indicate deeper compatibility or settings issues that need to be addressed.

Part 2: Reasons Behind Battery Drain on iOS 17/18/26

iOS17 beta battery drain can be caused by a variety of factors, some of which are related to the update itself and others that might be coincidental.

• New Features and Settings

Every iOS update brings exciting new features—but these upgrades often come at a cost. Many of the enhancements introduced in iOS 17/18/26 operate in the background, leveraging more system resources such as CPU, GPU, and network connectivity.

• App Compatibility

Sometimes, app developers need time to optimize their apps for the new iOS version. If apps are not optimized, they might consume more resources and battery power than usual.

• System Bugs

One of the common causes of iOS 17/18/26 battery drain is the presence of bugs or glitches in the initial release. Major software updates often introduce hidden performance issues that may not surface during beta testing but become apparent once rolled out to millions of users.

• Battery Health

If your device's battery health was already degraded before the update, it might become more noticeable after the update due to increased demands on the battery.

To evaluate your battery usage and your battery health, you can check it through the iPhone Settings. To find this information:

• Step 1: Locate "Settings" > "Battery."
• Step 2: In the Battery settings, you can overview your iPhone’s activity, which shows how you spend the battery. You can see the data within the past 24 hours or the last 9 days.

Otherwise, you can also find an option called "Battery Health." Tap on it to see “how healthy” your battery is. The Maximum Capacity tells you the health of your battery as a percentage. A higher percentage indicates a healthier battery.

Part 3: How to Optimize Battery Settings on iOS 17/18/26

Alright, now it's time to address the key question at hand: How do we effectively optimize our iPhone's battery performance after upgrading to the latest iOS 17/18/26? As the operating system evolves, so do the methods for enhancing battery life.

In this segment, we'll get into actionable steps and techniques that will let you harness the full potential of your device's battery while navigating the new features brought by iOS 17/18/26.

1) Enabling Low Power Mode to extend battery life

Low Power Mode is an iPhone feature that conserves battery life by reducing power consumption. When enabled, it limits background activities, decreases performance, and turns off non-essential features. Therefore, your device can last longer.

• Step 1: Go to the Battery settings again
• Step 2: Under the Battery settings, locate and toggle on "Low Power Mode."

This mode conserves energy by reducing performance and disabling non-essential features. Your iPhone's background activities, automatic downloads, and some visual effects will be limited. It may save you from battery drain on iOS 17/18/26.

2) Configuring background app refresh

The second solution that you can try is configuring the background app refresh. Background app refresh involves managing which apps can update their content when you're not actively using them. This helps save battery by preventing unnecessary background activity and data usage.

• Step 1: Open the iPhone’s Settings."
• Step 2: Look for and tap "General"> "Background App Refresh." Make sure the toggle is on.

3) Adjusting display and brightness settings for efficient power usage

This method is very simple yet effective. With just a few taps, you can fine-tune your display and screen brightness with ease directly from the Control Center.

• Step 1: Unlock your device and make sure you're on the home screen or within an app.
• Step 2: Swipe up of your display to bring up the Control Center.
• Step 3: Once the Control Center is visible, locate the brightness bar. It usually looks like a vertical slider with a sun icon on it.
• Step 4: Now decrease the brightness by dragging the brightness bar downwards.

Alternatively, you can also adjust it in the Display & Brightness settings.

If you’ve tried all the standard battery-saving tips and the iOS 17/18/26 battery drain issue still persists, a deeper system-level glitch may be the cause.

Tips for preserving battery health over time

Now you understand why our devices' battery health has become crucial. iPhone has integrated into nearly every facet of our lives, transforming the way we work, connect, and unwind. If your iPhone’s battery drain after updating to iOS 17/18/26, we have some tips for preserving your iPhone’s battery health:

1. Minimize drain during high-resource activities

If you engage in power-hungry tasks like gaming and video streaming, it can strain your iPhone’s battery. To minimize drain, adjust the game settings like screen brightness and graphics quality.

2. Use Airplane mode to save battery

Airplane Mode isn't just for flights. It's handy to conserve battery when you're not using wireless connections. It turns off Wi-Fi, cellular, and Bluetooth, which can be useful for offline work, reading, or tasks not requiring an internet connection.

3. Charge smartly for battery longevity

How you charge matters. Avoid letting your battery run very low before charging, as it strains the battery. Likewise, don't keep your device plugged in at 100% for too long. Aim to maintain battery levels between 20% and 80% for optimal lifespan. If possible, use adaptive charging features for smarter charging management.

4. Mind extreme temperatures

Extreme temperatures can harm your battery. Keep your device away from direct sunlight, hot cars, or very cold conditions. High heat can speed up battery wear, while extreme cold can temporarily reduce battery capacity. If you're using your device in harsh temperatures, try to stay within safe operating ranges.
