How to Disable Power Management Feature in iOS 11.3 on iPhone

  • This performance management feature has been specifically designed for iPhone and does not apply to any other Apple products.
  • Unexpected shutdowns generally take place when there is a higher chemical age, colder temperatures or low battery state of charge.
  • In extreme cases, shutdowns may happen more frequently and eventually render the iPhone completely unusable.
  • By ideally managing performance peaks, iOS prevents the device from unexpectedly shutting down.
  • You can check out the performance management feature that dynamically manages maximum performance to stop unexpected shutdowns and can choose to turn it off. Simply open Settings app on your iOS device>Battery and head over to the Battery Health section.
  • It gets activated only after an unexpected shutdown first occurs on a device with a battery that has diminished the ability to offer maximum instantaneous power.
  • It supports iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus.
  • The iPhones that are operating at full battery capacity (like the newly launched iPhone X, iPhone 8/8 Plus) there is no toggle to disable throttling feature that causes iPhones with degraded batteries to run more slowly.
  • “iPhone 8, iPhone 8 Plus, and iPhone X models use a more advanced hardware and software design that provides a more accurate estimation of both power needs and the battery’s power capability to maximize overall system performance. This allows a different performance management system that more precisely allows iOS to anticipate and avoid an unexpected shutdown. As a result, the impacts of performance management may be less noticeable on iPhone 8, iPhone 8 Plus, and iPhone X. Over time, the rechargeable batteries in all iPhone models will diminish in their capacity and peak performance and will eventually need to be replaced.” – Apple

Note: When you update your iPhone to iOS 11.3, the performance management will be initially disabled. It will be activated if the device subsequently experiences an unexpected shutdown.

The Battery Health screen shows information on maximum battery capacity and peak performance capability. “Maximum battery capacity” measures the iPhone’s battery capacity relative to when it was new.

Normally, batteries start at 100% when first activated. However, when they chemically ages, they will have lower capacity. And therefore, their battery life will be shortened.

A normal battery is able to retain up to 80% of its original capacity at 500 complete charge cycles. The company offers the one-year warranty that includes service coverage for a defective battery.

When the Performance of your iPhone Is Normal

If your iPhone’s battery condition can support normal peak performance and performance management features aren’t enabled on it, you’ll see this message:

 “Your battery is currently supporting normal peak performance.”

When the Performance management is applied to your iPhone

If the performance management features have been applied to your iOS device, you will see this message:

“This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again.”

Disable Power Management on iPhone

The power management feature is automatically enabled when your iPhone experiences unexpected shutdowns. Once the normalcy returns to your device, you can disable the power management. To do so, launch Settings app → Battery →Battery Health and tap on the disable button.

When the Performance management is disabled

When you disable the applied performance management feature, you will see this message:

“This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. You have manually disabled performance management protections.”

In case your iPhone experiences another unexpected shutdown, it will be re-applied.

When the Battery health of your iPhone is unknown

If iOS is not able to determine your iPhone’s battery health, you will see this message:

This iPhone is unable to determine battery health. An Apple Authorized Service Provider can service the battery. More about service options…

It could be due mainly to the unknown battery part or having an improperly installed battery.

When the Battery health is affected

If your iPhone’s battery health has drastically degraded, the following message will appear.

“Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity. More about service options…”

In some cases that need more extreme forms of the performance management, you may notice the following effects:

  • Longer app launch times
  • Lower frame rates when scrolling
  • Backlight dimming
  • Lower speaker volume up to -3dB
  • Gradual frame rate reductions in some apps
  • In the most extreme cases, it will also disable camera flash
  • Apps refreshing in background may require reloading upon launch

There are several important functions that are not affected by the performance management feature. They are:

  • Cellular call quality and networking throughput performance
  • Captured photo and video quality
  • GPS performance
  • Location accuracy
  • Sensors like gyroscope, accelerometer, barometer
  • Apple Pay

That’s pretty much it!

Wrap up:

I’m delighted to see this highly efficient power management feature in iOS. What’s your take on it?
