Energy saving mode on iPhone: This is what the energy saving mode brings

2 min

The power saving mode on the iPhone has been around since iOS 9 from 2015. We explain what the mode does and how you can switch it on.

Turn on / off iPhone power saving mode

In order to set up a shortcut for the energy saving mode in the control center on the iPhone, at least iOS 11 is required. Then the “Settings> Control Center” menu must first be called up. Then you can tap on “Energy saving mode” under the heading “Additional controls” and the icon moves up under “Include”. With a tap and hold on the three bars, the position of the icon in the control center can be changed. A tap on the minus, however, removes the symbol from the control center.

If the iPhone power-saving mode is set up in the control center, it only needs to be called up with a swipe from the lower edge of the display upwards (older iPhones) or from the right corner of the display to the center (newer iPhones). With a tap on the half-filled battery symbol, you can immediately switch the energy-saving mode on or off manually – the cumbersome way via “Settings> Battery> Energy-saving mode” is no longer necessary.

The energy saving mode can also be anchored in the control center.

What does the power saving mode bring?

When the battery capacity of your iPhone reaches 20 percent, a pop-up window will automatically appear advising you to switch on the energy-saving mode. Of course, this recommendation does not necessarily have to be followed. A warning appears again when the battery capacity is 10 percent.

Power saving mode

The power saving mode deactivates various features on the iPhone.

When the energy saving mode is activated, the iPhone can be used a little longer before it has to be plugged in. However, some features may run slower or update. In addition, some processes may not be carried out again until the power-saving mode is deactivated or the iPhone is charged to at least 80 percent.

These things change the energy saving mode on the iPhone:

  • E-mail retrieval is disabled
  • “Hey Siri” is turned off
  • Background updates for apps are turned off
  • Automatic downloads will be disabled
  • Some visual effects – also within apps – are reduced
  • Auto-lock is set to 30 seconds by default
  • iCloud Photos are temporarily paused
  • 5G will be switched off (except for video streaming)

When the power saving mode is switched on, the battery is displayed in yellow in the status bar. When the iPhone is charged above 80 percent, the power saving mode is automatically deactivated. According to a study by Wired, when the energy-saving mode is activated, only 70 percent of the total power is required – which ultimately means about 1.43 times longer runtime. Depending on usage, one to three hours more can be extracted from the battery.


  1. The power saving mode has been available on iPhones since iOS 9, and finally on iPads since iPad OS 15.
  2. With a battery capacity of 20 percent and again at 10 percent, iOS automatically suggests activating the energy-saving mode.
  3. Since iOS 11, the mode can be anchored under “Settings> Control Center” in the control center and can be activated manually even faster.
  4. The energy-saving mode switches off or restricts various features of the iPhone, such as background updates or visual effects.
  5. Depending on usage, up to three hours of additional runtime are possible.
