I'm not sure, but I believe it has something to do with the resistance of the extra-long cable.

Electrical resistance is directly proportional to length. So less current ends up going to the cable, and the battery takes longer to charge up.

Bottom line: the shorter the better. Just stick to 1 m USB cable.

Eh Fudgey... I think he meant the 3M certification, not the length...

As in 3M, the company?

Then it beats me why that would be the case, although since the OEM cable works, then he should just use it.

yup, that would be from what I think it is...

Some people tend to keep a few cables at different places. Such as 1 at workplace, 1 at home, 1 in bag etc etc...

Hello there,

I think I may have an answer to that question.

But first, can I ask if you are charging through a wall outlet or a PC/Laptop?

Hmmm, guess it wasn't the problem I expected. Then I may not be able to help you.
