Some Apple websites are starting to push wireless charging pads to their readers, on the basis that the new iPhone will support wireless charging.
Don't be too quick on the draw, wait until the iPhone is announced before buying up any chargers.
There's a good reason for this, although Apple is a member of the Qi group, that doesn't mean it will be supporting Qi charging in the new iPhone.
The Apple Watch set exactly this precedent. Despite using Qi charging it will only work with MFi certified chargers.
So any investment in chargers made before Apple reveals its iPhone charging technology could end up being wasted.
