Oticon OPN Flight Mode only turns off Bluetooth?

Am trying to find a way to extend battery life. Since I do not use Apple products and do not stream music, etc. I do not need the Bluetooth always looking for a link-up, unless I am missing some benefit if having it on.

Also, I believe that flight mode does not turn off the Near-Field Magnetic communication use for Twinlink. Correct?

Am I missing any other wireless radios in/on the OPNs?

Thanks for your time and responses.

who says the is “stupid enough” to always look for a device to pair with. If you think you can extend your Battery life in a significant way by doing it, go ahead.

What…you don’t remember a certain “doctor”? :slight_smile:
I’m sorry I don’t have any input for your question as I don’t have OPN’s but I agree with the motivation. I turn off bluetooth, nfc, gps and data on my cellphone. If I wish to use any of those features I turn them on. Then off again when done. Totally extends battery life. I can still call and text (except pictures that needs data) of course.

btw I didn’t attack you, I simply pointed out, that by logic shouldn’t be implemented that way, as by many industry standards to extend battery life.

If you think that’s sooo insulting that you need to tell me to refrain from giving my opinion, then the problem is on your side.

I don’t know why you overreacted to my response but you did, and you attacked me, not the other way around. If you can’t see that then let me turn this around and give you the advice that you shouldn’t read in a public forum.

MFI hearing aids do NOT use Bluetooth unless paired to a phone, so there’s no point even trying to play with it. BTW, what’s the problem with battery life? Batteries are cheap and you could always get the rechargeable update for the OPNs if the issue isn’t cost.

It depends on where you live I guees. The dispenser charge as much as 5€ for a pack of 6, where I live. amazon charges 20€ for 10 packs = 60 batteries. However sometimes amazon marketplace sellers send you poorly stored batteires that vary in perfomance alot, or simply old ones with an expiration date whitn the same year or the next year.

So I understand saving batteries, even in the US if you’re not close to a Costco.

The is between the and not with the iPhone so it’s not relevant or advisable to have it turned off, nor does it give you an option to turn off NFMI anyway. The whole point of using NFMI is because it’s very low energy in the first place, and NFMI is not for streaming, but for data communication between the 2 OPNs, so it should always be on anyway.

I’m not an expert on Bluetooth but I would imagine that the iPhone is the active device seeking/discovering the presence of the passive device (the OPN or whatever speaker it’s been paired to) to connect to that passive device. I’d imagine that if there are multiple paired devices present, then the iPhone will probably ask you which paired device you’d want to connect to. Otherwise if there’s only one paired device present, then it’d automatically connect to that paired device.

If this is the case, I’d imagine that the active device (the iPhone in this case) seeking the presence of a paired device will be the one burning up more energy, compared to a passive device like that of the OPN which probably still transmits some kind of signature representing its identification, albeit a low energy signature not significant enough that you can really save a full day or two worth of battery juice over. But yes, it still does transmit its signature id, hence there’s a flight mode option to turn it off. But that’s probably more to conform to FAA regulation than to save battery energy.

If you think about it further, it’s not the handshakes between the iPhone and the OPN that consumes a lot of energy. That’s why Oticon can still have the ON app available on Android phones to send commands to and get status from the OPNs and not worry about burning up battery juice from the OPN from communicating with Android phones via the ON app using regular (power hungry) standard Bluetooth 4. The vast amount of energy is spent on the data streaming rather than the command handshakes, so as long as you don’t stream data between the iPhone and the OPN, the significant saving in battery is already realized.

I think this is one of those threads that a manufacturers representative section could solve really quickly. Seems to me the main question is what does airplane mode turn off and does turning it off save any battery life since the user is not planning to use any Bluetooth either way.

Do we even need to activate flight modes on ? I have never heard any announcements specific to HAs. The manual on one pair I had told how to turn it on and off. My current manual does not mention flight mode at all.

Psocoptera: Nor do mine. It might be that you can’t be telling people with medical devices to turn off their medical devices. You CAN tell someone to turn off their phone.
I’m not sure it’s even just for bluetooth. I seem to think there’s some 2.4ghz going on between them. 2.4 is common for other transceiving doodads too. I would suspect though that the transmitting power of ’s would be so miniscule as to be not worth troubling over.

Gentlemen, I did not want this thread to create such speculative confusion. My question about Bluetooth battery drain is from many iPhone websites that recommend shutting off Bluetooth to conserve battery life, such as:

"How To Save Battery On iPhone: Improve Your Phone's Life | Macworld1

How to improve iPhone & iPad battery life

Bluetooth is considered to be a battery drainer. If you’re not using it to connect to a speaker, headphones, or other accessory, or to use the Continuity features in iOS, then switch it off.

It would definitely be a great help if an Oticon rep would jump in to clarify my question.

Thank you to most of you who chimed in here.

yeah I think the should be in listening mode. The phone should initiate the search, HA listens, gets a Start command from the Transmitter and then sends out it’s information if it listened to a pairing request. I’m not sure if it constantly sends out its “ID”. I think it should simply be in low energy listen mode.
Only a pairing request command should force it to send out a handshake. A constant ID transmit to the outside world would be uneccessary. Think it’s more like a caller -> responde bus system.

The HA itself also is mainly the receiver, it shouldn’t initiate a search, since it doesn’t stream anything to the outside world, it mainly receives. So therefore the idle power draw on the HA itself should be extrodinary lower than that on a iPhone, or any other transmitter/ caller. Bluetooth on sometimes simply means constant search mode, which is only on the transmitter part, not the HA.

Everything said here makes a lot of sense to me. It also seems consistent with what Steve_b showed below, that the concern should be turning off Bluetooth on the iPhone/iPad to save battery drain on the iPhone/iPad. The concern shouldn’t be to have to turn off on the OPN to save the OPN battery.

Having said that, a startup of the OPN probably involves the OPN sending out an ID momentarily while the iPhone is in the discovery mode to allow the iPhone to be able to “discover” it and pair with it if not already. But after that momentary ID output upon startup, it makes sense that the OPN remains in listen mode and strictly receiving streaming data from the iPhone if the iPhone is in BT mode and determines that it’s connected to the OPN from the last time it was active.

Unfortunately there is no OPN rep on this forum that I know of who can answer your question.

And the source you cited above is about saving the battery on the iPhone by turning off on the iPhone.

But your question originally is actually about turning off BT on the OPN to save battery on the OPN, which is a different discussion than the source you cite above.

And I think the discussion involving the iPhone being the active transmitter seeking connection and transmitting the data stream and therefore draining the battery unless BT is turned off is consistent with the source you cited above.

But there’s no source confirming that turning BT off on the OPN will save any battery on the OPN itself. Like I said, turning BT off on the OPN for flight mode is most likely just a conformance to the FAA requirement to have all electronic devices to have an airplane mode and BE in airplane mode during flight. But it is very unlikely that it’s a feature designed to save battery power. And there’s no such feature to turn off BT to save battery power because it is not necessary if the OPN is only in the low power listen mode, and as long as there’s no incoming data stream then there’s no BT power consumption for the OPN.

it’s simple only in the first seconds after you close the battery door, the is on waiting if you want to pair. After that, when you don’t pair, BT is switched off. If you have paired once it will turn on BT always waiting to connect the paired device. I

I guess I am lucky, my Dispenser provides free batteries and free for the lifetime of the HA so battery life is not a concern to me. I stream both audiobooks and music and generally the batteries last 4 days
