Next-generation iPhones likely to focus on internal improvements.
Leaked Schematics Suggest 128 GB Storage Option for iPhone 6
Previous rumors have suggested Apple has been working on a 128 GB iPhone model, with one rumor claiming the higher capacity module would debut in the 5.5-inch model only. The same leak also predicted Apple would drop the 16 GB option, introducing a 4.7-inch iPhone 6 model with two storage options (32 and 64 GB) and a 5.5-inch model with three storage capacities (32, 64 and 128 GB).
This new parts list from GeekBar appears to refute that claim, opening the door for Apple to add the 128 GB model as a fourth storage option for consumers. Apple launched its first 128 GB iOS device in early 2013 with a mid-cycle upgrade to the fourth-generation iPad. The option expanded across the iPad lineup with the October 2013 introduction of the iPad Air and iPad mini with Retina display, which also are available in 16 GB, 32 GB and 64 GB capacities. The 128 GB option has, however, yet to make its way into the smaller iPhone and iPod touch form factors.
