Running the BaseMark OS II 2.0 compound benchmark outed some peculiar results. The 32GB iPhone 7 Plus we had for review has class leading performance but according to the benchmark, it didn't came even close to the 128GB iPhone 7 we reviewed previously. The culprit - its memory score was rather poor (memory as in storage not RAM).

This discrepancy led us to test other iPhone 7 Plus models. Indeed, depending on the on-board storage, the three iPhone 7 Plus models scored vastly differently on Basemark OS II with the memory breakdown score being the sole reason for those differences. The 32GB flavor scores 851 in Memory, the 128GB achieves 1319 points, and the 256GB puts up a score of 3052.

Our further investigation into the issue with other benchmarks revealed that it's particular the poor write speeds on the 32GB model that are to blame.

This could be either because of technology limitation - such are the SSD speeds - the more storage the more channels and thus better speeds. Or Apple could also be using different vendors for its storage chips so the difference in storage speed could be due to the chip maker and not the difference in size.

We did a blog post on the subject and you can learn more about the issue here.

In practice it would be really hard to spot the difference in performance between the three models in real life. They are equally fast and there is no lag whatsoever. However, there is a noticeable performance difference in tasks like copying or saving large files (refer above to our blogpost on the subject).

Apple's iPhone 7 Plus is a best-seller that doesn't even need an advertisement. Nearly a month after its launch, the Plus is a tough one to find on the market, and some of the orders are yet to arrive.

Apple made sure it has put enough novelties to make it an attractive purchase and a worthy upgrade. The lines of people and the depleted stock prove that. People are buying the Plus model, lots of people are opting for the new iPhone upgrade program, too. And in the wake of the Note7 fiasco, many people are choosing Apple over Samsung once they return their dangerous Notes.

The future seems bright for the new iPhones and Apple has nothing to worry about. Next year is iPhone's tenth anniversary, so we are sure we'll be treated to yet another pair of competition crushing smartphones. Until then, the iPhone 7 Plus is the best iPhone yet. Time for an upgrade?
