Apple has hit a few snags while developing its much-anticipated iWatch device, according to sources cited by The Information. Issues include challenges with the screen technology, battery problems, and possible manufacturing bumps.

The last point cites an industry executive saying the company halted advanced prototyping of some “unknown pieces” with one manufacturer late last year. Apple regularly tests different manufacturers, and none of these problems suggest the product has been delayed as a result.

The report also suggested Apple has a “sizable team” working on the device and noted the speculation that it will likely run a slimmed-down operating system or a variant of iOS, because anything else would require more powerful hardware not suitable for such a small device.
