If you are planning to buy iPhone 7 and choosing to go with 32 GB version and have a thought in mind that every iPhone 7 model are made equal then you are wrong in that sense.
According to the testing done by GSMArena, the results tells us that the speed of the storage within the 32GB iPhone 7 is significantly slower than that in the more expensive 128GB iPhone 7. Reading data from the storage of the 32GB version of the iPhone 7 was 200Mbps slower than the 12GB version, 656Mbps and 856Mbps respectively. The difference in read speed over 600Mbps is unlikely to be noticeable in day-to-day usage.
The story is same for the iPhone 7 Plus as well, According to New York-based Cellular Insights, which conducted tests using networking equipment, the iPhone 7 Plus smartphones with model numbers A1778 and A1784, including those available in the UK and Europe, performed noticeably poorer than those with model numbers A1660 and A1661, including those available in the US.
The A1660 and A1661 models use a modem supplied by Qualcomm, a common supplier of modems and processors to many Android smartphones, including the new Google Pixel where else the models A1778 and A1784 iPhone 7 Plus smartphones have an Intel modem chip that connects them to the 4G network.
Milan Milanović from Cellular Insights said: “In all tests, the iPhone 7 Plus with the Qualcomm modem had a significant performance edge over the iPhone 7 Plus with the Intel modem. We are not sure what was the main reason behind Apple’s decision to source two different modem suppliers for the newest iPhone.”
So now the truth is out there, think twice before you choose your storage option for iPhone 7.
