Back in May when Samsung announced the Galaxy S3, it mentioned that the device supported wireless charging as well. However, to enable wireless charging users needed to buy an official inductive backplate from Samsung, which the Korean giant never released. The Galaxy Note 2, which was unveiled at IFA in late-August, met with the same fate.
Thankfully, an XDA member took things in his own hands and came up with a wireless charging mod for the Note 2 that takes only 10 minutes and costs less than £10. The mod has been confirmed to work on the International Galaxy Note II (N7100), N7105, along with the AT&T and Sprint variants of Note 2. T-Mobile Note 2 owners can also get wireless charging on their device, but that would require some additional steps and mods.
The mod is not for the faint hearted though, as it requires soldering. There is another mod which does not require any kind of soldering and can be found here.
