The soap opera of iPod nano 1G in the land of the rising sun has been going on for a long time, but it seems that things are gradually resolving over there. The Japanese government recently released a document [PDF; 70KB] in which it counts the total number of nanos that had their batteries replaced.
In June and July, there were 294 exchanges; until august 11, 553 more substitutions were made, a sign that the subject gained traction with the media coverage. After the 11th, when Apple had to post a notice on its website, that number exploded to 4,994. In the total for this quarter, 5,821 nanos had their batteries replaced to avoid overheating accidents or explosions.
The Japanese government will continue to follow the case closely and has pledged to release regular reports on the situation. The recommendation remains that consumers who notice that their iPod nano 1G undergoes an abnormal warm-up should contact Apple as soon as possible to arrange a battery replacement. Fortunately, these cases are isolated from a component supplier, which has been largely restricted to Japan.
