Mobile Fun claims to have heard from an inside source that the dock will miss the handset's May 30 launch by some four months.
"We've just been told some pretty bad news relating to the Samsung Galaxy S3," the report states. "The Official Wireless Charger we've all been so excited about won't be released until September! So we're looking at nearly a four-month wait for the wireless charging dock."
"We have no further info at the moment on this - unfortunately the latest date for release is approx Sept 2012"
Samsung unveiled the Galaxy S3 during a press event in London last week. The smartphone will land with a 4.8-inch HD Super AMOLED display, Google's Android 4.0 Ice Cream Sandwich operating system, a 1.4GHz quad-core processor and an 8-megapixel rear-mounted camera.
Earlier this week, the handset was confirmed as the official phone of the Olympic Games. Athletes will use the device's NFC technology to gain access to the Olympic Village and purchase goods around London.
Samsung is yet to confirm that the Galaxy S3's wireless charging dock has been delayed.
