That’s a lithium-ion battery cooking out

He said he threw the phone to the ground where it burnt the floor and melted a nearby electrical cord, resulting in the school being evacuated and the Airdrie fire department called in.Shayne’s mother, Tammy Cryderman, said she’s filed a complaint with the Canadian Safety Board because she fears the product could end up hurting someone else. Tammy Cryderman said her son complained that when he was using the phone, the screen began to get blurry and fuzzy. Shayne informed his mother that it began sparking and making high-pitched squealing noises before it started to melt and puff up in his hand.
Calls to the Apple media relations line seeking comment were not immediately returned.A technician at Apple’s telephone help center said he was unable to comment, but noted that Cryderman’s case was extremely rare.A representative who answered the phone at the Apple Store in Calgary’s Market Mall deferred a call for comment to Apple’s media line, but also noted that it was not common for iPhones to combust like how Cryderman’s claims.Ryan MacKay, a service technician at WestWorld Computers in Calgary, said he’s never personally seen a severe case like the Cryderman’s before.
Although WestWorld doesn’t service iPhones, they do deal with Apple/Macintosh computers and iPods, which also commonly use lithium-ion Dell Vostro A860 Battery Original . .“Google‘exploding lap tops’ and you’ll see lots of video of lap tops going up in smoke.” Although he had no dealings with Cryderman’s phone, he did say in his experience it sounded like a battery issue.
“They are superior in a lot of regards to the Nickel Metal Hydride … and all the other [batteries] they used to use because they can hold way more power. In 2006, millions of Sony manufactured lap top Original Dell WU841 Battery 56WH were recalled after it was discovered that in some rare cases, microscopic metals made during manufacturing could cause a short-circuit if they came in contact with other parts of the Dell D044H battery cell, potentially leading to a fire. Because Shayne’s iPhone was on a pre-paid plan and was a device he had bought second hand, there were some delays in getting a straight answer from Apple in regards to replacing the phone, Tammy Cryderman said.
“Now [Apple] said they’ll send a cheque and [will] replace his phone with whatever phone he chooses,” she said.“What I’m trying to do now is see if they can do a recall on these phones for people because if they’re that unsafe, or if it’s a problem with the battery itself, that needs to be corrected before someone really gets hurt.”Both older model iPhones and newer model phones commonly use lithium-ion Dell Vostro A840 Battery Original .An Airdrie high school student was lucky to avoid injury after he claims his Apple iPhone internally combusted and began smoking, hissing and expanded in his hand before he threw it to the ground.
Shayne Cryderman, a Grade 11 student at George McDougall High School, said he was texting on the phone at school March 23 when it suddenly got hot and began expanding. “It [expanded], it got really big and then it started to smoke a bit and then combusted inside,” “There’s been exploding laptops Original Dell T749D Battery 56WH for the last few years. It’s basically because of the way lithium-ion as a technology works.
Cryderman, 16, said.“I would have never even thought something like that could happen,” she said. “You don’t think of these things when you buy this technology.“You don’t want to see someone else have this happen and have it be something a lot more serious than what happened with my son.”
“That’s very scary,” she said. “People need to be aware and cautious about it.”The iPhone in question was an older generation model and not a newer 3G version, Shayne noted.
MacKay said he has never seen an iPod or Apple computer suffer a similar fate as Cryderman’s did.“I’ve seen really bubbled up lithium-ion batteries, but that’s just the technology as a whole and the way the lithium-ion batteries work as a class,” MacKay said. “But nothing ever fire related.
“That’s a lithium-ion battery cooking out,” he said.“But having way more power in them makes them way more volatile.During a telephone interview with MacKay, he explained the situation and asked what would likely cause an electrical device to act in a manner like Shayne Cryderman’s. The recall affected many companies who manufacture and selllaptops,including Apple.The mother and son said they have been in contact with Apple representatives about replacing the phone.
