Another new rumor can be added to the list, this one also involving the larger screened iPhone 7 Plus. According to a report out of China published today, Apple will be offering a version of the phone with 256GB of native storage. That is double the 128GB that tops the amount of internal memory available on the Apple iPhone 6s and Apple iPhone 6s Plus. To put that in perspective, the OG Apple iPhone offered buyers 4GB, 8GB or 16GB of ROM.
In addition, we now expect Apple to bump the capacity of the battery on the iPhone 7 Plus to 3100mAh from the 2750mAh power plant currently employed on the iPhone 6s Plus. That is nearly a 13% increase in the capacity of the power plant inside the phone.
Even though a recent China Mobile road map showed that a 4-inch Apple iPhone 7c might be released in April, we don't expect to see the iPhone 7 and iPhone 7 Plus to see the light of day until September.
