Obvious solution to make Note 7's 'safe' for transport?

JohnP, its time to give it up. Neither Samsung nor the FAA have any interest in wasting time on a dead product. Turn in your phone and move on with your life.

You totally misunderstand. This is simply about the idea that if the battery is fully discharged, it makes it impossible for the battery and phone to self-immolate.

"Most mobile phones, laptops and other portable devices turn off when the lithium-ion battery reaches 3.00V/cell on discharge. At this point the battery has about 5 percent capacity left."

So, if you calculate that as 5% of standby time, quite a long time actually.

Now we're getting close. Later, when I get a chance, I'll figure out how much energy that 5% represents. Probably in Joules. That should give us an idea of how much heat that could generate in the process of being dissipated in the battery cell itself.

JohnP, I think it's a shame that you can't have a theoretical discussion in this forum! I've truly never seen anything like this in all my days! If you decide to keep yours forever, that's fine with me. I can tell that you have a good head on your shoulders.

Hey, great minds think alike, right?? I'm still loving my Note 7! I just recently got two of the Samsung clip on wireless charging battery packs - 3100mAh each, for $15 each! Now I can have extra power readily available if I ever run low and am not near an outlet. I also bought a wireless charging pad for my desk at work, and for my windshield mount in the car. Now I feel good that I won't physically wear the USB port hardware out with plugging in the charging cable a million times a day.

I'm still keeping my eyes and ears peeled for further information out of Samsung about any more findings on the cause of the meltdowns. I also felt some validation for my hypothesis/question that I started this thread with, when I read that Samsung is once again saying they're rolling out the 60% battery charge cap update to all the devices still out in the field in Europe. It says right in the information it's designed to limit the amount heat that can result from the battery failing. I'm still willing to bet money that a 'fully' discharged battery, at least, discharged enough so that the device will no longer power on, is for all practical purposes inert at that point.

I've continued to try and imagine ideas for how the meltdown problems arose. I have to assume they are thinking of all these things too, but here's some questions I'd have. Seeing as simply using a different battery manufacturer didn't appear to cover the issue, how else could the battery be compromised, in a way that fits the observations? Do they have any records that allow them to trace back manufacturing and assembly activities by IMEI? If so, the IMEI of each phone that failed and was reported could tell them if there was a particular piece of assembly gear or location that correlates, or a person or shift of assembly workers that correlate. Also, if there is any large number of new but uninstalled batteries still sitting somewhere, did they carry out an inspection of them, like measuring their dimensions, checking their weight, and scrutinizing them all for any appearances of anomalies? What if, regardless of which battery manufacture was used, some of the batteries from each were just slightly larger in one or more of their dimensions than they were supposed to be, and that resulted in those batteries being jammed too tightly inside the device? And then, the battery was deformed by that just enough to then direct short out, internally, soon afterwards? Or, was there some shift worker that didn't operate an assembly machine properly, and occasionally slightly damaged some batteries during each shift? Where all the phones assembled in one factory, or multiple ones? Were some batteries slightly damaged during shipping to the factory, like say, if they were the ones in the bottom of a pallet, and the forklift force that lifted the boxes impacted them slightly, but not all the others? I could keep on thinking of all kinds of possibilities. It seems like there could easily be an explanation that results in saying that only some devices would have ended up with the lurking problem, and many more wouldn't have. I know there's probably no comfortable way after the fact, with millions already out the door, to identify specific devices believed to be at risk verses any that aren't. And so, Samsung just ran for the exit to try and get out of the mess as quickly for itself as it could. Kind of like chewing off its leg in a trap, rather than taking the time to figure out how the trap operated and getting it open, to save as much of the leg as they could.

I just received one of those fancy "fireproof" boxes to ship back my Note 7

I called Samsung and told them that I'd turned it in a month ago, and they advised me to call Sam's Club and determine the phone's disposition, since Samsung still thinks I possess the phone. I called Sam's and they said that all Note 7s turned in are still there, waiting for the appropriate shipping materials - they can't get rid of the things!

Great!! Ask them if you can have yours back!

The_Chief said:

No thanks. The Note 8 is right around the corner and I can wait.

Right around the corner?

The_Chief said:

Yep.

I didn't say how BIG the corner was

Yes. Right now I'd call it a blind curve. I don't see how they have a leg to stand on with releasing ANY new devices at all, until they publish a compelling explanation for the battery failures, and a compelling resolution. With reports of S7 meltdowns also ominously occasionally appearing, I think Samsung is on very thin ice, and walking on egg shells, concurrently.
