A new problem was discovered with iPhone 7 and iPhone 7 Plus these days, some models performing worse than others in terms of data transfers, or their modification. More precisely, we are talking about the iPhone 7 and iPhone 7 Plus with 32 GB of storage space, these units performing worse than those with 128 GB/256 GB of storage space, in terms of reading data.
A series of tests carried out by gsmarena reveals that Apple uses poor-quality NAND Flash memories in the iPhone 7 and iPhone 7 Plus with 32 GB of storage space. According to their tests, the difference in data reading speed is 10x, while editing a 4-minute 10K movie is almost 4 times more difficult than on an iPhone 7 with 128 GB of storage space.
The performance tests show much bigger differences between the terminals than the real ones, but despite this, they exist and question the way Apple thinks about its terminals. Doing tests on my iPhone 7 Plus, I noticed that the difference between its writing times and those of an iPhone 7 128 GB are not as big as those described by gsmarena, the difference being halved.
iPhone 7 – performance with poor quality memories
Following the gsmarena test, the editing time of a 4-minute 5K video clip on the iPhone 7 Plus 32 GB is almost as long as the editing time of a 4-minute 10K clip on the iPhone 7 128 GB. That is, in my case the editing lasted 15 seconds, while on the iPhone 7 128 GB the editing lasted 17 seconds, the difference being big. Repeating the test on the iPhone 6S Plus 16 GB, it needed more than 2 times more time to edit the same video clip.
In the performance tests, the differences vary between 10% and 400%, enough to matter when you edit large files on your terminals. This performance problem also gives me an answer to the question regarding the identical performance between iPhone 6S Plus 16 GB and iPhone 7 Plus 32 GB, both editing video clips equally slowly in my case.
To be honest, I didn't expect to see such big differences in terms of writing data on the terminals, but they also exist in terms of reading, but it doesn't really matter that much. Practically, when you edit large files, or when you transfer data from/to the terminal, you will notice big differences between the terminals with these types of storage space.
When you use the usual applications, apart from games, you will not notice such big differences in terms of writing speeds, nor in terms of reading speeds. Big differences could exist in loading the games, or the levels in them, but everything depends on the application you use.
The Apple company uses various types of storage media in the iPhone or iPad, and last year this problem had the opposite effect, i.e. terminals with a lot of storage space were slower. This year it seems that the iPhone 7 and iPhone 7 Plus with 32 GB of storage space are slower, so you have to take this into account when making a purchase.
