Apple’s low power mode is important for the battery on an older iPhone to last longer. Typically, iOS will automatically turn off power saving mode when your iPhone is charged to 80%. However, you can use shortcuts automation to keep power saving mode on forever. Here̵
First, open the Shortcuts app that Apple added as the default app in iOS 13. If you can’t find it on your home screen, slide one finger down the center of your screen to open Spotlight. Enter “shortcuts” in the search bar and tap the “shortcuts” icon.
Under Shortcuts, tap the Automation button at the bottom of the screen.
If an automation is already listed here, tap the plus sign (+), then tap the Create Personal Automation button to add a new automation. If no automation is listed, tap the Create Personal Automation button.
In the “New Automation” window that appears, scroll down until you find “Power Saver”. Tip it on.
Next we define the conditions under which the automation takes place. Select “Is Off” with a check mark and make sure that “Is On” is not selected. Then tap on “Next”.
Now let’s define the action that will be taken when the automation condition is met. Tap “Add Action”.
In the panel that appears, find “Low Power” and then tap “Set Low Power Mode”.
If you see the Set Power Saver action, Turn Power Saver On is enabled by default. Let it be. This is the only action we need. So tap on “Next”.
On the next summary screen, tap the Ask Before Running toggle to turn it off. When this option is enabled, a shortcut will appear every time the automation is triggered, which can get annoying very quickly.
When a confirmation dialog appears, tap Don’t Ask.
Then tap on “Done” and your automation will be set.
Whenever Power Saver is turned off (either by you or automatically by iOS), Power Saver is automatically turned back on. To start it you have to activate the energy saving mode manually in the settings (Settings> Battery> Energy saving mode) or with a Control Center shortcut. Your iPhone will then stay in power saving mode indefinitely.

How to turn off automation in sleep mode
After using automation for a while, you may find that power saving mode cannot be turned off as usual because it turns back on automatically. But fear not: it’s easy to turn off automation so you can turn off power saving mode again. Here’s how.
First, open “Shortcuts” and tap the “Automation” button at the bottom of the screen. In the list of automations, tap the automation you created “When sleep mode is off”.
On the automation details screen, tap the “Enable this automation” switch until it turns off. This will disable automation.
Then tap on “Done”. If the automation is deactivated, the energy-saving mode can be switched manually as usual. If you ever want to turn the automation back on, just visit the automation again in the shortcuts and toggle the “Enable this automation” switch on.
Finally, it should be noted that the iPad from iPadOS 14.0 no longer includes an energy saving mode. However, this could be added in a future update. Currently this automation only works on the iPhone.
