Turn off Phonak hearing aid in app?

So I have the phonak lumity plus the cros receiver. I’m finding that the battery life is not the best but will make it through a working day. My issue is preserving battery life in those longer days when I cannot charge it so I have started to turn off the cros when it’s not needed.

Currently I have to hold the button on the hearing aid to turn it off. Is there an easier way to do this? I was hoping that the app would have that feature but cannot see an option for it. Or would it be possible to reprogram the on device button to power off using a single press?

Thought I’d try here before asking my audiologist.

My answer is, “No.” But in an openminded spirit, I’ll say, “I don’t think so.”

As @brec so succinctly noted: “NO”.
2 ways to turn off a rechargeable HA:
Put them in the charger, or long press volume down button.
Maybe you should investigate the travel charger, so you can do a quick charge during a break, or any time convenient.

I don’t think so, but you can mute it in the app. I would think that would conserve the battery, but I haven’t tested it.

Thanks everyone. The travel charger sounds like an option.
