I knew it's impossible to use a chip to prevent abuse. But shouldn't we make that point clear to consumers? Should we add "proper handling of rechargeable battery" to primary schools if not nursery schools textbooks? -- @~@ Remain silent! Drink, Blink, Stretch!

OTOH, as an owner of a Galaxy S7, of which there have been no similar occurances, my suspicion is that there is a manufacturing defect that is limited to the "Note" batteries. Which brings a question to mind... does Samsung manufacture their own batteries for the Note 7? I recently read an article stating that Samsung was building a factory in Europe to manufacture Lithium batteries for automobiles, BMW initially. So if there is a manufacturing problem and it's within Samsung's organization, it's very likely they won't release any more information than they are forced to. |

Isn't it silly in the very beginning? Hey, Battery-Man, you'll be pleased to note they're truncating the charge cycle to 60%. This is to enhance safety for those people too stupid to participate in the recall effort. (You know, the same people here who drive their cars forever, on the spare wheel they found in the trunk of their car. Those people.) http://www.cbc.ca/news/technology/sa...arge-1.3759648 That means, they'll be avoiding Stage 2 completely. And checking the fill state (somehow) to determine when to stop. You cannot use time alone to do that (like stop at 45 minutes), because if the battery is at 40%, and the target is to charge to 60%, they need to use the "fuel gauge" to tell when to stop. http://batteryuniversity.com/_img/content/ion1.jpg I have no idea how they're doing that, whether the battery management chip is programmable, or the poor CPU will have to be on for the entire charging process. And return to the run-state, if the charger enters Stage 4 and tries to top up the battery later. Paul |
