Every smartphone we build is about balance. It is a constant trade-off between performance, cost, and real-world experience. No device can have the absolute best of everything without increasing costs significantly. The key is knowing where to invest to maximise the user experience.

Choosing UFS 2.2 for the Phone (3a) series wasn’t about cutting costs, but about putting resources where they matter most. A faster storage standard like UFS 3.1 sounds great on paper, but in everyday use, its benefits are often marginal compared to optimisations in software, battery life, and display quality.

We’ve seen discussions about UFS 2.2, and we understand why some might question the choice. UFS 3.1 has a bigger number, so it must be better, right? In benchmarks, yes. But in actual use, it’s not that simple. Storage speed is one factor in overall performance, but it’s not the only one. What really makes a phone feel fast is a combination of storage, RAM, CPU performance, and software optimisation. That’s why we focused on Nothing OS, ensuring that the Phone (3a) series delivers a fast and fluid experience in real-world use.

UFS 2.2 vs UFS 3.1: What It Means in Daily Use

For most tasks like messaging, web browsing, and social media, the difference between UFS 2.2 and UFS 3.1 is almost impossible to notice. App launch times are nearly identical, and even with heavier apps, the difference is often measured in fractions of a second. Large game installations and big file transfers are where UFS 3.1 pulls ahead, but these aren’t everyday tasks for most people.

Performance in Context

Sequential and Random Read/Write Speeds

Storage speeds can be measured in two key ways: sequential (continuous data transfer) and random (accessing scattered bits of data). Think of it like reading a book. Sequential speed is flipping through pages in order, useful for tasks like video playback or copying large files. Random speed is jumping between sections, crucial for launching apps, loading game assets, and keeping background processes running smoothly. In real-world smartphone use, most daily interactions rely more on random read/write speeds, which is why Nothing OS is optimised to make app launches and multitasking feel just as fast on UFS 2.2 as on higher-tier storage solutions.

The comparison below shows the sequential and random read/write speeds of two devices, one with UFS 3.1 (left) and the other with UFS 2.2 (right). With UFS 2.2, Phone (3a) series holds up well in real-world performance due to optimisations at the system level.

File Transfers and System Efficiency

Sequential write speeds are important for large file transfers, system boot times, and tasks like video editing. The Phone (3a) series uses NTFS optimisation to process files more efficiently, reducing the time it takes to move data across the system.

App Loading and Multitasking

The speed at which apps launch and switch depends on how quickly small bits of data can be accessed. The Phone (3a) series optimises this process through Smart Clean technology, which removes unnecessary system files created by user activity and reorganises stored data to boost read and write speeds. This ensures apps load quickly and multitasking remains smooth. The result? Performance on par with UFS 3.1 devices in many cases.

Memory Copy Speeds and AI Performance

Transferring data quickly across different memory areas is essential for tasks like graphics rendering, AI-driven features, and machine learning. With the Snapdragon 7s Gen 3 chipset and Qualcomm’s AI Engine, Phone (3a) is designed to handle these processes efficiently.

Gaming Performance

Frame rates and smooth gameplay don’t rely on storage speed alone. Through efficient data management and Nothing OS optimisations, the Phone (3a) series ensures stable performance in games like BGMI and Genshin Impact, delivering a smooth experience comparable to devices with UFS 3.1 storage.

Addressing the Future-Proofing Question

We’ve noticed that as the initial complaint about UFS 2.2 being slow didn’t hold up, the argument has now shifted to whether it is future-proof. Here’s the reality: even today, UFS 2.2 is more than capable of handling everything a smartphone is expected to do.

A smartphone’s longevity depends far more on how well its hardware and software are tuned together. With Nothing OS updates, ongoing optimisations, and well-integrated hardware, the Phone (3a) series will continue to perform reliably for years. Future-proofing isn’t just about having the latest spec on paper; it’s about ensuring that performance stays consistent over time.

If the concern is that future apps will slow the phone down, it’s worth noting that modern software is built to scale across different hardware configurations. UFS 2.2 already delivers high-speed performance, and with Nothing OS enhancements, users will continue to experience smooth performance in daily tasks, gaming, and content creation.

We appreciate the conversations happening around this and will always prioritise real-world performance over spec sheet comparisons. As always, we’re listening.

    I own a nothing phone 2 and am a huge admirer of the nothing brand. As a result of my recommendation, several of my friends have purchased a variety of nothing products and are very pleased with them. However, people are now complaining that there is a delay or processing lag when shooting photos. I believe this is due to UFS 2.2 and LPDDR4X RAM. I’m not sure why this brand ended with this negative decision. I believe this is for cost cutting. Nothing phone 1 comes with UFS 3.1 and is really quick. Because of UFS 2.2, the camera has a processing delay, and switching between apps is delayed. I believe this is a horrible decision. Please express your opinion here.

      Merged 1 post from Processing delay due to UFS 2.2 in 3a phones. Is it a bad decision?.

      People want the latest and greatest technology, but they don’t necessarily need it. Without asking where the usefulness or advantage of this or that technology is in their use.

      The user is not the best person to recommend a particular technology in his equipment.

      On a PC while waiting to take for example the most efficient SSDs that can be bought, without having a motherboard or a processor capable of managing its

        For now, Nothing 3a 8/128Gb feels as smooth as my Snap 8 Gen 3 12/512Gb Honor Magic V3.

        Nothing actually written an essay

        but we can really sense the difference between camera processing speed and shutter speed… this all deal waith ram and storage mostly.

        becausethe best picture have big size of photo file size … and processing colour and details… all required speed and ram management…

        Definitely we can sense it comapring nothing phone 1 with ufs 3.1 and 3a with 2.2…

        the justification is not needed when there is no issue … but if a brand is trying to justify then there must be acceptable fact that company knows it.

        The reality in hand feel of 3a and 3a pro with ufs 2 is worst than a scrap !

        now your essay says it all !

        Thanks for the explainer, Raymond. What I find amusing here is even in the face of numbers and graphs there are armchair engineers here who think they know more than the engineers behind the product. 😅

        I’ve had my Phone (3a) for about a week and while using it it feels the same as my Phone 2 - and seems to take better pictures. I don’t play Genshin Impact or PUBG or games like that but it’s nice to I could if I wanted to.

        How narcissistic can you be?

        I love what Nothing does, the UI, the themes, the ads, they’re so freaking cool but this post defending the UFS 2.2 is such a narcissistic defence on your unnecessary ‘compromise’.

        Yes I agree with nothing PV there is not greater d/f ufs 2.2 and 3.1, most important thing for a smartphone is software optimisation and nothing is providing us, many people are inspired from Chinese brand they are giving this giving that, material is not important quality is important and nothing as company doing exactly same thing giving us the quality through its software part, have you seen when u bought a Chinese phone you have to disable the notification off some apps and why we have to do this bcoz of adds they are giving us forcefully, so guys always remember nothing os is great OS, i will rate this OS after pixel OS, not even samsung OS defeat the nothing OS, so appreciate nothing work.

        Pls let me if anyone have anyone i will answer on the behalf of nothing ( do not think i m nothing biased guy i am a user who support software not hardware ).

        Thank you
