iPhone in energy saving: how and why to activate the mode

If you’ve ever masterfully prolonged an important conversation with only 1-2% battery remaining, you definitely owe a debt to the iPhone power saving mode. This iOS feature kicks in limiting or deactivating some functionsall in the noble attempt to ensure that the iPhone battery lasts longer.

Apple presented the iPhone’s energy saving mode with the advent of iOS 9, presenting her as a hero for those precarious moments when the battery is on its last legs. But it’s good to ask yourself about it how it actually works this mode and understand if this is the case, given that it ensures longer battery life activate it permanently.

We see it in this article.

  • 1. How iPhone Power Saving Mode works

    Energy saving is one functionality integrated into iOS which comes to the rescue when the battery drops to 20% and then again to 10%. As the Cupertino company explains, it is designed to reduce energy consumption so as to Extend iPhone battery life. In power saving mode, the battery icon turns yellow, indicating that it is active. It automatically turns off when the battery charge reaches 80%.

    As reported on Apple’s official support pages, the iPhone’s energy saving mode brings a series of changes to reduce the amount of energy consumed to conserve battery charge. These include:

    • Turning off 5G (except for video streaming)
    • Auto-shutdown of the screen after 30 seconds of no activity
    • Reducing display brightness
    • Reducing iPhone display refresh rate with ProMotion
    • Elimination of some visual effects
    • Pause iCloud photo sync
    • Pausing automatic downloads
    • Pause email retrieval
    • Stop updating apps in the background

    In addition to this, it must be kept in mind that saving energy disables the display of videos in HDR, the always-on display on iPhone 14 Pro and Pro Max, the automatic playback of videos and reduces CPU and GPU performance.

    The effectiveness of power saving mode varies depending on users and scenarios. Some estimates suggest it can extend battery life by about one and a half times, while others report minimal differences. The impact depends on usage patterns, apps and settings. To truly evaluate its effects, you need to try it and monitor the performance of the device.

  • 2. How to activate iPhone power saving

    To manually enable this mode, go to Settings > Battery. Alternatively, you can go to the iPhone Control Center or ask Siri directly. To permanently activate iPhone power saving, there are two ways.

    The simplest method is to turn on power saving mode whenever the battery is below 100%. This way, iPhone is always in power saving mode, but it can also create backups, complete downloads and receive updates when connected and charged to 100%.

    Otherwise, you can create a personal automation using theShortcuts app. So the iPhone will automatically go into energy saving whenever the battery percentage drops below a certain threshold (at the user’s discretion).

    What you need to do is launch the Shortcuts app, select “Automation” at the bottom of the screen, then tap the blue “ buttonCreate personal automation“. Now, scroll down and select “Battery level”. In the tab that opens, tap on the “Less than: 50%” then move the slider to the right to choose the battery percentage you prefer, such as 60%.

    So we set the condition to activate an action, a trigger in short. Now we need to configure the action to take every time the battery drops below 60% or any chosen percentage.

    On the screen “Actions“, tap on the blue button “Add action“. Then type “Set the energy saving mode” in the search box and activate it. Instead, deactivate the entry “Ask before running“. In this way, when the battery drops below 60%, the iPhone will activate energy saving, without asking.

    Through another automation we can also ask Siri to read the battery percentage. Leaving the same 60% trigger already set, we will need to add two more actions: “Get battery level” and “Read text”.

    At this point, when the battery drops below 80%, in addition to automatically activating energy saving, we will also have a voice alert from Siri which it will read the percentage of charge left.

  • 3. Disable Power Saving Mode on iPhone

    If you feel that this mode does not meet your expectations, you can deactivate the automation simply by accessing the Quick Commands app and disabling the switch next to the “Enable this automation“.

    To completely cancel it, you need to swipe left on the power saving mode automation on the home screen, then tap the red “Remove”.

    Alternatively, you can create a customized version of power saving mode by changing iPhone settings. For example, you can save battery by preventing apps from updating in the background or by adjusting brightness settings.

    Furthermore, in Settings > Battery > Battery status and charging you can see the maximum battery capacity, as well as set optimized battery charging and clean energy charging. If your iPhone’s maximum battery capacity has dropped to 80% or less, there will be a “Important message about the battery” which warns that the battery has deteriorated significantly and needs to be replaced or restored.
