32GB iPhone 7 is Slower Than Larger Storage Versions Claim Tests


Unbox Therapy released a video the other day showing that the 32 GB iPhone 7 is significantly slower than the 128 GB or 256 GB versions, and additional testing conducted by others confirms that. Furthermore, some models may have poorer 4G reception than others (via The Guardian).


Testing by GSMArena and Unbox Therapy revealed that reading data from the storage of the 32 GB iPhone 7 was 200 MB slower than the 128 GB version, which isn’t noticeable in everyday usage. What is noticeable, though, is the write speed: when you save data (music, videos, photos, etc.) on your iPhone, well, that counts.

As it turns out, the 128 GB iPhone 7 had a write speed of 341 Mbps, which compares to the 32 GB version’s 42 Mbps. GSMArena confirmed Unbox Therapy’s findings, reports the Guardian.

Why? According to How to Geek on why smaller capacity SSDs are slower:

The higher capacity variants of an SSD model often get their higher capacity from simply having more NAND flash chips of the same type as the lower capacity variants. Having more NAND flash chips allows for a design where the controller on the SSD can access more data in parallel, allowing for higher speeds.

So in reality, this is by design, as a limitation of SSD by capacity si

But there is more: New York-based Cellular Insights has found that iPhone 7 Plus smartphones with model numbers A1778 and A1784, have poorer 4G reception that those with model numbers A1660 and A1661.

The difference between the models is the modem: The A1778 and A1784 models carry an Intel modem chip, while the A1660 and A1661 versions incorporate a Qualcomm modem. The Intel-inside iPhones show at least 30% worse network performance (some up to 75%) than those using a Qualcomm modem.

History seems to be repeating itself: The dual sourcing of chips doesn’t seem to work out well for users. Last year Apple issued a comment regarding TSMC vs. Samsung A9 battery life. It remains to be seen whether Apple considers these reports interesting enough to reply. So far, it has refrained from giving any explanation.

    In other news, a 128GB SSD is slower than a 512GB, just like in the MBP’s….I really can’t imagine it even makes a difference in day to day use though

    Apple did this intentionally so pple can avoid the 32GB iPhone. Apple wants more of our cash by all means possible.

  • FragilityG4

    The more likely scenario is that the slower speed SSD is cheaper for them to buy thus yielding higher profits.

    It’s silly to say that they did this on purpose so people avoid the 32GB version since this is not advertised and someone found out about it by testing. That’s like them not advertising the dual cameras on the Plus and when you pick it up you say “hey look at this!”

    At the end of the day anoyone buying a 32GB phone doesn’t care.

    Does the Plus 32 have the same issue? It doesn’t seem to mention it in the article or the video.

    Interesting theory and it reinforces my point that Apple has not done this to push people into higher capacity phones to make more money. That theory is just plain silly.
