Save battery automatically when your phone runs low

When your battery drops below a level you choose, dim the screen, switch off Wi-Fi and Bluetooth, and get a heads-up — automatically, with a free Android app.

Describe it

Type in New flow:

“When battery drops below 20%, lower brightness to 30%, turn off Bluetooth and tell me.”

Step by step

  1. Trigger: Battery level → below 20%.
  2. Actions: Brightness → 30%, Bluetooth → Off, Show a notification.
  3. Optional: a second flow on Charger connected that puts brightness back.

Good to know

  • Brightness and notifications work in the background. Bluetooth and Wi-Fi toggles use Accessibility and need the phone unlocked.
  • Pick a level that suits you — some people prefer 30% with a gentler set of actions.

Try it yourself. AnyFlow is free, with no sign-up. Get AnyFlow or read the docs.
