Arun Maini, the author of the YouTube channel Mrwhosetheboss, said that the batteries on some of his old Samsung smartphones were swollen. Other bloggers and users have confirmed this trend.
In July of this year, Maini was going to shoot a video about Samsung and searched for the right phones in his collection of more than 600 smartphones. At this point, he discovered that the battery in his Galaxy Note 8 had bulged and cracked the back cover. The same thing happened with the Galaxy S6 and S10.
After Maini announced it on Twitter, other bloggers confirmedthat faced similar problems on Samsung smartphones.
According to Maini, at the moment he has eight Samsung smartphones with swollen batteries. With devices from other manufacturers, everything is in order.
The blogger keeps all smartphones on the shelves. They are located vertically in special mounts printed on a 3D printer. The room temperature is usually 22°C.
Bloating occurs when the electrolyte material in batteries, which is normally in a liquid state, begins to break down and then turns into a gas, iFixit tech editor Arthur Shi said. According to him, the batteries of older iPhones swell less often than Samsung, because they have much less capacity.
The problem could also be caused by a manufacturing defect, said Kelsey Hatzell, assistant professor of mechanical and aerospace engineering at Princeton University.
Samsung is aware of the problem and is looking into it, company spokesman Chris Langlois said. [The Verge]
With the rest of the old smartphones, everything is fine.
