iPhone Battery Drain After Update: What You Need to Know

iPhone battery low

Are you experiencing rapid iPhone battery drain after a recent software update? It can be frustrating to see your once-reliable device suddenly lose its power faster than ever. But fret not! In this article, we'll explore the causes of this issue and provide you with practical solutions to extend your iPhone's battery life once again.

Understanding iPhone Battery Drain after update

A. Common Causes of Battery Drain

Before diving into the update-related concerns, it's essential to grasp the common reasons behind iPhone battery drain. These culprits include power-hungry apps, excessive screen brightness, background activities, and push email settings that flood your inbox with updates.

B. The Impact of Software Updates

Software updates are designed to enhance your iPhone's performance and security. However, they can sometimes have unintended consequences, such as increased battery drain. This happens due to changes in how the system and apps interact. Let's explore how to tackle this issue.

Identifying the Update Culprit

A. Monitoring Battery Usage

Your iPhone has built-in tools to help you identify which apps are consuming the most battery power. Go to "Settings" > "Battery" to view a breakdown of app usage. This insight will help you pinpoint the problem.

B. Checking Background Apps

Some apps may continue running in the background, eating up your battery. Review and restrict background app refresh settings for optimal control over which apps can use resources when not in use.

Steps to Mitigate Battery Drain

A. Adjusting Screen Brightness

Reducing screen brightness can significantly impact battery life. Experiment with lower brightness levels that are comfortable for your eyes, especially in low-light conditions.

B. Managing App Background Refresh

iOS allows you to control which apps can refresh content in the background. Disable this feature for non-essential apps to conserve battery.

C. Optimizing Push Email Settings

Constant email updates can be a major drain on your battery. Switch from "Push" to "Fetch" for better control over how often your device checks for new messages.

Dealing with Rogue Apps

A. App Updates and Background Activity

Ensure that all your apps are up to date, as developers often release updates to address battery-related issues. Monitor which apps are active in the background and restrict those causing trouble.

B. Uninstalling or Restricting Misbehaving Apps

If an app consistently drains your battery, consider uninstalling it or adjusting its settings to limit its background activity.

Additional Tips for Battery Conservation

A. Location Services and GPS

Location services can be power-hungry. Review which apps have access to your location and restrict unnecessary permissions.

B. Push Notifications

Limit push notifications to essential apps only. Fewer interruptions mean less battery usage.

C. Widgets and Dynamic Wallpapers

Widgets and dynamic wallpapers can look impressive but consume resources. Use them sparingly to reduce battery drain.

Battery Health Check

A. Checking Maximum Capacity

Understand your battery's health by going to "Settings" > "Battery" > "Battery Health." Check the Maximum Capacity percentage. A lower percentage may indicate a battery replacement is needed.

B. Calibrating the Battery

Occasionally, calibrating your battery can improve accuracy in estimating battery life. Drain your battery completely, then charge it to 100% without interruption.

Getting Support

A. From Apple Support

If your iPhone is still within the warranty period, you can contact Apple Support for help and assistance. For hands-on assistance, visit your nearest Apple Store.

B. Visiting an Repair and Service Center

Bring your iPhone to a reputable service and repair center like Mac.Infinity to get it diagnose and address hardware or software-related issues affecting your battery. There is no charge for diagnostic advices.

Avoiding Future Battery Woes

Preventing future battery drain is just as important as solving the current issue. Stay vigilant by regularly monitoring your device's battery usage and updating both iOS and your apps to the latest versions.


Experiencing iPhone battery drain after an update can be exasperating, but it's a common issue with manageable solutions. By understanding the causes, monitoring your device's usage, and implementing the tips provided in this article, you can enjoy longer-lasting battery life on your iPhone.


1. Can I downgrade to a previous iOS version if I experience severe battery drain after an update?

  • Yes, you can downgrade to a previous iOS version, but it's a complex process and may not be supported for older devices. It's generally recommended to wait for Apple to release a fix or optimize your settings.

2. How often should I calibrate my iPhone battery?

  • Calibrating your battery once every few months is sufficient for most users. You don't need to do it frequently unless you notice significant discrepancies in battery life estimation.

3. Why do some apps drain my battery even when I'm not using them?

  • Some apps use background activity to perform tasks like refreshing content or sending notifications. You can control these behaviors in your settings to reduce battery drain.

4. Is it safe to restrict location services for apps?

  • Yes, it's generally safe to restrict location services for apps that don't require your location to function properly. This can help save battery life and enhance privacy.

5. What should I do if my iPhone's battery health is below 80%?

  • If your battery health is below 80%, it's a good idea to consider a battery replacement.
