The source listing shows desktop models A1347, A1418, A1419, A1481, A1862, A1993, A2115 and A2116.  Those are: the current Mini, 21" iMac, 27" iMac, Mac Pro, iMac Pro, Unknown, Unknown, Unknown. 

Apple has always used consecutive model numbers for the 21" and 27" iMacs - A1207/A1208 from 2006, A1311/A1312 for 2009, A1418/A1419 for the modern design from 2012-now.  They don't change model numbers for speed bumps so the A2115 and A2116 models could likely be all-new iMac designs, or a pair of completely new but related desktop things.

The A1993 could be the new Mac Pro getting a placeholder in the filings, or a new Mini, or some new desktop thing.  Model numbers only ever increase, so it is a slightly older design than the new potential iMacs.

The other listings are for portable devices A1466, A1534, A1708, A1932, A1989 and A1990.  Those are: the 13" Air, 12" MacBook, 13" Pro, Unknown, 13" Pro Touch and 15" Pro Touch.  A1932 got its model number before the current MacBook Pro models, so it is something Apple has been working on for a while.  This could definitely be a new MacBook that has been waiting for display or processor technology to reach maturity for mass production.

Why does every article along these lines oversimplify? If you have set an app to process in the background, especially one that uses location data, then force closing it will improve battery life. This is especially true for map applications.

While you are in East Texas, make sure to stop by the Samsung Ice Skating rink. The only open-air ice skating rink anywhere nearby! Samsung and other tech companies have been sponsoring miiiiiilions of dollars of events in that area for the past decade. Coincidence? I think not...
