- Trigger: Battery below 20%
- Power saving
- Brightness 30%
- Dark mode
- AOD off
- Auto-sync off

- Scan the code above, then turn the routine on. The pack includes the matching "restore on charge" routine — see the Build it tab to add it by hand.
Import the file

- If › Battery level › Drops below › 20%.
- Then › Battery › Power saving › On.
- Display › Brightness › ~30%.
- Display › Dark mode › On.
- Lock screen and AOD › Always On Display › Off.
- Accounts and backup › Auto sync data › Off.
- Name it Battery Saver, tap Save.
- Add a restore routine: new routine, If › Charging status › Connected, then set each action above back (Power saving Off, Dark mode Off, AOD On, Auto sync On). Battery-level triggers do not reverse on their own, so this second routine is what undoes it.
