Why Is My iPhone Battery Draining So Fast After the iOS 26 Update?

Several factors can cause your iPhone battery to drain quickly. Check if your device has any of the following common issues:

• High display brightness
• Extreme ambient temperatures
• Outdated apps
• Fully charging/discharging the battery
• Battery-draining apps
• Keeping Location Services on all the time
• Poor battery health
• Excessive notifications
• iOS 26 bugs

How to Check Battery Health and Usage

To maintain healthy battery performance, it’s recommended to check your battery health and usage regularly.

Here’s how: Open Settings ＞ Battery ＞ Battery Health & Charging. If the Maximum Capacity is below 80%, your battery performance may be significantly reduced.

How to Fix iOS 26 Battery Drain Issues

Now that you know the possible causes and how to check battery health and usage, let’s explore the fixes.

This guide introduces 9 easy and effective methods to help extend your iPhone’s battery life.

1. Turn On Optimised Battery Charging

iPhone batteries naturally lose efficiency over time since they are consumable components. While aging can’t be stopped, you can slow it down.

The Optimised Battery Charging feature helps reduce battery aging.

Here’s how to enable it:

1. Open Settings ＞ Battery ＞ Battery Health & Charging
2. Turn on Optimised Battery Charging
   

   

2. Follow Insights and Suggestions

The “Insights and Suggestions” section in your Battery settings provides personalized tips. For example, it may suggest reducing High Brightness.

You can also disable Raise to Wake, which helps conserve battery life.

3. Optimize iPhone Settings

Adjusting certain settings can significantly extend battery life:

• Use Wi-Fi instead of mobile data — Wi-Fi consumes less power.
• Enable Low Power Mode — This reduces background activity until you recharge.

Here’s how:

1. Open Settings ＞ Battery
2. Turn on Low Power Mode
   

   

• Manage Location Services — Turning this off completely saves battery but disables it for all apps. Instead, adjust settings per app under Allow Location Access.

4. Update to the Latest Software

iOS updates often improve performance and fix bugs that cause battery drain.

Go to Settings ＞ General ＞ Software Update ＞ Download and Install.

5. Avoid Extreme Temperatures

iPhones perform best in environments between 16℃–22℃ (62°F–72°F). Prolonged exposure to heat above 35℃ (95°F) can permanently damage battery capacity.

In very cold environments, reduced battery life is usually temporary and will return to normal once the device warms up.

6. Avoid Fully Charging or Discharging

Keeping your iPhone fully charged or completely drained can shorten battery lifespan.

Ideally, keep it around 50% or enable Optimised Battery Charging, which delays charging beyond 80% until needed.

7. Remove Certain Cases While Charging

Some cases trap heat during charging, reducing battery performance. Remove the case if your device becomes warm.

8. Limit Battery-Draining Apps

Check which apps consume the most power (as explained above). If you notice one draining heavily, limit its usage or close it when not needed.

9. Disable Battery-Draining Notifications

Frequent notifications wake the screen and drain power.

Here’s how to reduce them:

1. Open Settings ＞ Notifications
2. Tap Show Previews ＞ Never
