Just in case you wanted even more evidence that a miniaturized version of the HTC One is in the works, a newly-leaked document that purportedly comes from inside O2 Germany is here to provide you with that. The doc, shared by Mobiflip, lists the HTC One mini in both silver and black variants alongside its HTC One sibling. Also listed on the document is an "HTC One Max" in silver, which is likely the HTC T6 that's rumored to be coming to market with a 5.9-inch 1080p display and quad-core Snapdragon 800 processor.
Both the HTC One mini and HTC One Max have been the subject of several leaks in recent months, with the One mini even posing for a few photos. The One mini is expected to arrive with a 4.3-inch 720p display and Snapdragon 400 processor, two features that aren't quite high-end but could provide respectable performance for consumers interested in a "smaller" smartphone. A launch for the shrunken One is rumored to be going down sometime in July or August, so it may not be long before we finally get to see how HTC's One design translates to a smaller form factor.
In addition to these unannounced HTC handsets, a couple of mysterious Nokia products are included on this leaked document. The two devices appear to be codenamed "Eros" and "Mars." Unfortunately, there's not much known about either item right now. Mobiflip suggests that "Eros" could be a typo for "EOS," but the::unwired points out that "Eros" and "Mars" happen to be the names of some Greek gods, so it's possible that they could mean something. For now we'll just have to file the names into the back of our heads.
