@Volusiano : When you open up the battery tray and momentarily disconnect the power supply to the Polaris chip, are you not then obliged to do the Genie2 reset? (I dunno … just asking.)

That’s a good question, Jim. I don’t know either. I sure hope that Oticon designs the More smarter than that → allowing a temporary disconnect without having to reprogram anything, unless it’s a new battery so things should be reset to allow for the new statistics. I personally don’t think it would mess up anything as long as it’s the same battery so that existing statistics just continue on. But that’s just a guess from me.

@Volusiano: How would the device know whether it was a new battery or not? All I know is that unless there is a capacitor or tiny buffer battery in a clock circuit, interrupting the power for even a fraction of a second causes a reset to occur, requiring reinputting the initialization data.
(How did you get the neat arrow → never mind. Found the secret!)

You only lose the statistical data stored in the battery if power is lost only if you use RAM type memory (stands for Random Access Memory), which holds only temporary data while there’s power. When power is lost, the data in the RAM is gone.
But I suspect that the data would not be stored in RAMs because there can be too many reasons for complete battery power loss (like perhaps a complete draw down, or removal of the battery for some reason), which would make the statistical data too volatile and prone to be lost. Most likely, they store the statistical data in some kind of EPROM (Erasable Programmable Read Only Memory), in which case the loss of battery power would not wipe out the data because it’s the ROM type (that can be erased and rewritten into).
I suspect the device would only know if there’s a new battery in use if the HCP uses Genie 2 to tell the HA that a new battery is being used, thereby resets the data and restarts the statistical accumulation of usage. That’s why if it’s not done, then things get messed up because the usage data continues to be collected, but no longer on the original old battery that gets replaced.

@Volusiano: Let me take this opportunity to thank you, once again, for your time and effort in explaining these technical details. Your posts are always valuable to me, and are very easy for a lay person to understand.
Well, ROM being the case, you are correct that the OP can pop the battery compartment of his devices without fear … I suppose I react because the idea is frightening to me → too risky (
).
Picking up my repaired/replaced aids today.
I will ask to upgrade to 1.4 if not already upgraded.
Fingers crossed.

Had my 2nd set of replaced More aids upgraded to 1.4 yesterday, while they did stream to only the left while I had my iPhone 12 mini in my right pants pocket they did switch when I put the phone on the other side.
Not noticing any real difference, they would do that with 1.3 also.
Still concerned with battery drain, now the left is draining more than the right, so it seems to be the batteries or the aids, not the RX difference right to left causing the issue.
I’m going to monitor battery levels more closely for a while and see what shakes out.

That’s what I was thinking … along those lines maybe even the “slave” to that master drains quicker if it has to take the signal? No idea!
AH!! Verrrry interesting! I’ve been locked up in the Phonak world for so many years I had no idea.
@michael.letizia: Sorry you’re not having the good performance from your Oticon More hearing aids that @cvkemp Chuck and I are enjoying …
If it’s any consolation, the batteries in my More1s had to be replaced twice before they operated satisfactorily. Make sure they are recalibrated, and keep going back until they get it right!
[FWIW: I find that the lack of a clear detent in the Oticon rocker switch makes me want to push it down harder - to “floor it”, essentially - on the rare occasions that I use the buttons. Do you find the same?]

I just had the buttons fail on one of My Mores.
Had them replaced under Warranty.
First lost the Detent then failed completely a few days later.
That is why I don’t use the switch on my aids if I can do it any other way.
Yup … them PRC 9-year-olds mean well, but …
I agree the remote is the handiest device that I have
I keep mine in a little nylon bag, with
The catch for the lanyard sticking out of the end. It’s discrete, and keeps dirt and pocket lint out of the buttons. I can feel the protubulences on the buttons so I can tell them apart
I don’t have Oticon’s but I always use a remote for my Phonak’s for this very reason. The buttons failing!

I have had OPN, S1 and now More, first time I had a button problem.
I’ll think about changing my ways, but now with the answer call option I’ll be using them even more on the Mores’ (Pun intended)
