Apple traditionally holds its iPhone launch event in September every year, but there is no official announcement on the iPhone 7 event date yet. However, a fresh leak now points at a tentative launch time frame. The iPhone 7 may be launched in the third week of September, specifically in the week of September 12.
This time-frame comes from tipster Evan Blass, who is noted for his accuracy when it comes to leaks. Last year, Apple launched the iPhone 6s and iPhone 6s Plus on September 9, however it came to India a month later. The same pattern is also expected this year.
The iPhone 7 was expected to launch in three variants - iPhone 7, iPhone 7 Plus, and a new iPhone 7 Pro version. However, new leaks hint that Apple may just stick to two variants this year. There is also expected to be a new base storage variant - 32GB. The probable storage offerings are going to be shuffled to 32GB, 128GB, and a possible new 256GB variant.
Apple may also introduce a new dual camera setup in its large iPhone 7 Plus variant. There is also going to be the addition of the Smart Connector at the back, again exclusive to the large variant only. To accommodate all this new hardware, the iPhone 7 Plus may get a bump to 3GB RAM.
The variants are expected to sport slightly bigger batteries, and the new Apple A10 processor for faster performance. The Home Button is expected to perform multiple functions, and be Force Touch enabled. Because of the new chip (and if the rumoured death of 3.5mm audio jack is true), the iPhone 7 is also expected to be at least 1mm slimmer than its predecessor.
There's also a lot of chatter about the 3.5mm audio jack. Conflicting reports on the removal of the audio output make it difficult to really nail a presumptive conclusion on whether it will be included this year or not. There's also expected to be a new Space Black colour variant with this year's launch.
