Samsung Could Look To LG For Phone Batteries After Note 7 Debacle (cnet.com)

Posted by msmash on from the helping-each-other-out dept.

An anonymous reader writes: Samsung seems to be doing everything within its power to avoid a repeat of the great Galaxy Note 7 battery crisis of 2016. That might even include buying in batteries from LG, according to a report published on Monday. Samsung currently sources its phone batteries from Samsung SDI, a subsidiary of the company, and China's Amperex Technology, but could be set to diversify its battery suppliers by inking a deal with fellow South Korean company LG Chem. Reuters cites the Chosun Ilbo newspaper as saying there is "more than a 90 percent chance" of Samsung signing up LG to provide batteries for its phones starting in the second half of 2017.

      Nothing special. Battery chemistry is a bit on the iffy side for these types of batteries. Poor chemistry has been the cause of many fires and I suspected it in this case as well, despite what a bunch of no-name software developers looking to get their startup in the newspaper by pulling apart a device and declaring themselves experts in hardware have said about it.

      Then why would the issue have continued with batteries from a completely different manufacturer?

      Could be a mixture of things. One thing is certain. The overwhelming majority of fires were from Samsung SDI batteries, while 35% of devices out there had TDK batteries. The number of exploded TDK batteries could be counted on one hand, and stood at zero at the time of the first recall.

      It's like any electronics part. The manufacture and design of even a standard part makes for a few very different cases in resilience. This becomes especially apparent when you push the parts to the edge of their tolerance.

      Or maybe Samsung just doesn't like money anymore and thinks safely diversifying suppliers like this is a sound profit strategy when they could buy parts from ... themselves.

      As far as I know, Samsung hasn't really determined the actual cause of the issue. With a dozen incidents out of millions of phones, it's not purely a design flaw but a combination of manufacturing/design. Personally I'm speculating that some counterfeit batteries got into Samsung's supply chain and Samsung can't tell everyone that or confidence in Samsung will fall further.

      I wonder if this second-sourcing is a different issue than the battery clearance space. Having batteries from multiple sources just makes sense, especially another South Korean vendor. I think Samsung learned from its mistake with the Galaxy Note 7, so likely a replacement device is going to be a lot better, as Samsung has to get their rep back.

      If there were a way to unlock the bootloader for installing a custom OS on new Samsung devices without frying KNOX, I definitely would move a Samsung device. Otherwise, no thanks.

      I used to have an HTC Desire S, with removable battery. A drop from 5 cm with the wrong angle would temporarily disconnect the battery, leading to a power-off. I had to put in a spacer to push the battery harder against the spring contact. (it took quite a while to figure out what the problem was)

      I have a low-end LG L40 with removable battery. Every time I drop the phone, the back cover will come off and I end up with a separate battery, cover, and front. At least it immediately removed its own battery when I dropped it in the toilet. (phone is still working after a rinse in distilled water and thorough drying)

      And I have a Nexus 5 with "non-removable" battery. The back cover can still come off with some effort; the battery can be replaced although it's a bit more work. And I don't have the above problems with self-disassembly and flaky contacts.

      That reason is weak. When dropped disconnect the battery, it stop the battery from being used, which also stop the potential to short itself and explode.
