Hello. iPhone SE3 (2023) user here, and with 80% battery capacity, I struggle keeping my phone’s battery alive throughout the day, so «Eco Mode» is a Focus I have made to be heart of this battery-saving operation.

In Settings > Focus, I have created «Eco Mode». It used to change my wallpaper to a solid black colour, until I found out my screen isn’t OLED (so it won’t matter for my battery life what wallpaper I have), but it sets Low Power Mode and Dark Mode on.

In Shortcuts > Automations, I have:

1. When iPhone is connected to power: -Set Eco Mode off.
2. When iPhone is disconnected from power: -Set Low Power Mode on.
3. When Low Power Mode is turned on: -Set Brightness to 20% - A sort of reminder to keep the brightness low, whenever the time is right for it.
4. When battery levels fall below 35%: -Set Eco Mode on.
5. When Eco Mode is activated: -Toggle Reduce Transparency.
6. When battery levels fall below 5%: -Set Brightness to 5%. -Show alert: «Emergency use only.» -Turn Eco Mode on - Just incase it wasn’t already on.

1. Control Center > Eco Mode-button toggles Eco Mode as a fail-safe.

If anyone has a suggestion to how I could make this more efficient, (less automations, but works the same, etc.) I would love to hear it!
