Samsung recalling Galaxy Note 7 over fires
« on: September 02, 2016, 10:36:00 AM »

Posted in general tech area rather as it sounds like another battery issue, rather than being Samsung specific.

http://www.bbc.co.uk/news/business-37253742

Sympathies to Samsung here, I suspect it could have happened to any other manufacturer.  But modern battery tech does occupy a high ranking position on the list of things I worry about these days. :o

Just so much stored energy in a tiny package, it seems almost inevitable that sometimes, somehow, that energy will find a way to violently unleash itself?

Does indeed seem like a battery issue. :(
Hope they manage to get them all replaced before serious fire damage is done.

Thanks, I wasn't aware of that subtlety. :)

It's beginning to sound like this one's really quite a big issue...

FAA want to ban samsung galaxy note 7 from flights...

https://www.faa.gov/news/press_releases/news_story.cfm?newsId=20794

And Samsung seem to be going into serious panic mode, asking people to urgently surrender the phones voluntarily, rather than wait for a recall...

http://www.bbc.co.uk/news/technology-37329191

I personally predict, the statistics behind this issue might prove to be many many times worse than the 'few dozen phones out of two and a half million' that has been reported.   The 2.5 million figure is probably accurate as the number shipped, but I find it hard to believe this would be the reaction if it were really such a tiny proportion of phones that had proven dangerous.   :o

How do we fix this recurring problem? Regulations governing design, manufacturing and quality control of these dangerous parts?

The problem as I see it is the 'Adaptive Fast Charge' charger is charging at 12v, when the battery is only a standard battery of ?v (maybe 3.5v)

Oh dear, the replacements that Samsung are sending out, after recalling these devices, are also bursting into flames.   :o

http://www.bbc.co.uk/news/world-us-canada-37600014

When I started this thread I expressed sympathies to Samsung on the basis it could have happened to any manufacturer.   But in the light (no pun intended) of this latest news, it gets harder to defend them.   ???

Where I worked they were trying to develop a Re-chargeable Sodium–sulfur battery for the railway carriages use, these where very big a when they catch on fire you knew about it. :o
It's operating temperatures of 300 to 350 °C  :'(

For it to happen on the revised product is very bad, shows some serious lacking QC.

This issue is now main headline on BBC breakfast news, as well as top spot the online news.   Samsung are advising people to simply switch them all off until the issue is resolved.   :o

But my understanding of lithium batteries was that, if they have become defective and prone to combustion,  it is just as likely to happen when switched off as when switched on?    ???

They're saying it's not the batteries, it's another fault.

I don't know if this is relevant to this issue but when I got my S4 I found out later it was actually a different version. There were 2 types of S4. There were slight differences. I remember the one I have didnt have either 4g or that other high speed method on.

Also it was always 'dodgy' when it came to charging it. The charger adapter that you plug in to the mains has never worked properly. It just doesn't charge it. The only way I've been charging it as been via usb cables to my computer. I don't know if this is connected but just as all these stories started coming out I was charging my phone like usual at the computer, like I've done many times before. But now there was no charge and the phone was very hot. I took it out of the case I had it in (always had it in the case for years and never a problem), and I did buy a new battery to replace it as I'd heard it could be the battery. But since then its started charging fine again and no heat.

I also noticed if I put it in an open drawer of my bedside table, so its reachable if anyone calls. If it drops further inside the open drawer it got hot. I'm not sure why. Unless it was struggling to get a signal and thats why? I'd not noticed that before. I haven't re-tested the drawer position since the phone stopped getting hot again, and I still have the spare battery sat here. I never used it.

It's all history now
Quote
Samsung has confirmed that it is permanently stopping production of the Galaxy Note 7 smartphone after it was involved in dozens of fires and explosions worldwide.

In a regulatory filing in Korea late on Tuesday, the firm said it had made the decision to stop production for the sake of consumer safety, according to the Associated Press.

It was even top story on Radio 4 news.   Maybe just me, but I wouldn't have associated Radio 4's target audience with cutting-edge smartphones.  :-\

Maybe they'll be building it into 'The Archers' plot in a few weeks time? ::)
