Every time your iPhone battery reaches 20%, you will be presented with a pop-up window asking if you want to turn on power saving mode. For me, the answer is always yes, so I find it a bit annoying to tap this button every time. I solved this problem by setting up automation to turn on sleep mode without additional tapping.
To do the same thing on your own device, download Apple’s connections App and go to the automation Tab. Press the + Button in the upper right corner and select Create a personal automation.
Scroll to the bottom of the page and select Battery level and move the slider to the left on the screen until it is at 20% (or whatever battery percentage you want). To choose Falls under from the list of options below the slider and tap Next.
Now tap on Add action and type power saving mode in the search box above. To choose Set energy saving mode from the Action List and tap Next once again. Uncheck in the last step Ask before you run and tap Completed. Now your iPhone will automatically switch to energy saving mode.
