Both phones share a broadly similar footprint — nearly identical width and height — but diverge meaningfully in bulk and protection. The CMF Phone 2 Pro is noticeably slimmer at 7.8 mm thick and lighter at 185 g, compared to the Nothing Phone (3a)'s 8.4 mm and 201 g. That 16-gram difference is perceptible in daily one-handed use, and the tighter volume (99.8 cm³ vs 106.4 cm³) means the CMF simply feels less imposing in a pocket or palm.

Where the Nothing Phone (3a) fights back is in its IP64 rating versus the CMF's IP54. The critical digit here is the first number — dust ingress protection. A rating of 6 means full dust-tight protection, while the CMF's rating of 5 means only partial dust resistance. In practice, this matters if you regularly use your phone in sandy, dusty, or dirty environments. Both are equally rated for water resistance at level 4 (splash and light rain), so neither is suited for submersion.

In summary, the CMF Phone 2 Pro has a clear design and ergonomics edge — it is lighter, thinner, and more pocketable. However, the Nothing Phone (3a) holds a meaningful advantage in environmental durability thanks to its superior dust protection. Your priority decides the winner: form factor favors CMF, ruggedness for dusty conditions favors the Nothing Phone (3a).

On paper, these two displays are nearly twins — both are 6.77″ OLED panels running at 1080 x 2392 px, 120Hz, with essentially identical pixel density (~388 vs 387 ppi) and the same 800 nits typical brightness. For everyday viewing, scrolling, and media consumption, users of either phone will have a practically indistinguishable experience.

The meaningful splits emerge in three specific areas. First, the Nothing Phone (3a) claims a significantly higher contrast ratio of 5,000,000:1 versus the CMF's 1,000,000:1 — a spec that, if accurate in real-world output, would translate to deeper, more inky blacks and more vivid HDR content. Second, the CMF Phone 2 Pro counters with a dramatically faster touch sampling rate of 1000Hz compared to the Nothing's 240Hz. This matters primarily for mobile gamers who need ultra-responsive input recognition; for general users, 240Hz is already more than sufficient. Third, only the CMF ships with branded damage-resistant glass, offering a tangible edge in everyday drop and scratch resilience that the Nothing Phone (3a) lacks.

This group is closely contested. The Nothing Phone (3a) has the edge for media enthusiasts who prioritize display depth and contrast, while the CMF Phone 2 Pro wins for gamers and users who want screen durability. Neither phone dominates outright — the right call depends squarely on which of these two differentiators aligns with your use case.

Both phones are built on 4nm chips, but the silicon underneath tells very different stories. The Nothing Phone (3a)'s Snapdragon 7s Gen 3 pulls ahead of the CMF's Dimensity 7300 in every modern benchmark that matters: its AnTuTu score of 816,384 beats the CMF's 711,907 by roughly 15%, and its Geekbench 6 results — 1162 single-core and 3239 multi-core — are meaningfully higher. Geekbench 6 is the more current and representative test, so these figures carry real weight.

The CMF Phone 2 Pro does show surprising strength in Geekbench 5 multi-core (8046 vs the Nothing's 3242), but this is largely an artifact of how older benchmark versions interact with MediaTek's CPU core configurations, and should not be interpreted as a practical performance lead. What is genuinely notable on the CMF side is its significantly faster RAM speed at 6400 MHz versus the Nothing's 3200 MHz — though this advantage is partially offset by the Nothing Phone (3a) shipping with 12GB of RAM compared to the CMF's 8GB. More RAM headroom directly translates to smoother true multitasking and fewer app reloads when switching between demanding applications.

The Nothing Phone (3a) holds a clear performance edge in this group. Its combination of stronger real-world benchmark results and greater RAM capacity makes it the more capable device for demanding workloads, gaming, and heavy multitasking. The CMF is no slouch for everyday use, but the data consistently points in one direction here.

The rear camera systems on these two phones are remarkably close. Both feature a triple-lens setup with identical 50 + 50 + 8 MP configurations, 2x optical zoom, OIS, 4K/30fps video, and the same suite of manual controls and autofocus technologies. The only rear-camera distinction is a marginal aperture difference on the secondary lens — f/1.9 on the CMF versus f/2.0 on the Nothing — which is too small a gap to translate into any meaningful real-world light-gathering advantage.

The front camera is where a genuine split emerges. The Nothing Phone (3a) packs a 32MP selfie shooter versus the CMF's 16MP, which means the Nothing can resolve significantly more detail in portraits and group shots — particularly useful when cropping. The tradeoff is aperture: the CMF's front lens opens to f/2.0 compared to the Nothing's f/2.2, giving the CMF a slight low-light edge up front. Whether that extra light intake compensates for a 2x pixel count deficit in practice is debatable, but for users who prioritize sharp, high-resolution selfies in good lighting, the Nothing's sensor is the stronger spec on paper.

The Nothing Phone (3a) takes a narrow but clear edge in cameras, driven entirely by its superior front camera resolution. If selfie quality is a priority, the gap is meaningful. For rear photography, these phones are effectively spec-for-spec identical based on the available data.

This is the rarest outcome in a spec comparison: a complete tie. Every single data point in this group is identical across the CMF Phone 2 Pro and the Nothing Phone (3a). Both ship with Android 15, share the same privacy controls, productivity features, and system capabilities — from split-screen and picture-in-picture to dynamic theming, on-device machine learning, and offline voice recognition.

Notably, neither phone receives direct OS updates from Google, meaning both rely on their respective manufacturers for software rollouts. Neither supports Wi-Fi password sharing or focus modes, and both lack Quick Start. These shared omissions are worth flagging, but they apply equally and therefore do not differentiate the two devices.

The verdict here is an unambiguous draw. Based strictly on the provided data, the operating system experience these two phones offer is functionally identical. Any real-world software differences — such as custom UI layers, update cadence commitments, or exclusive software features — fall outside the scope of this dataset and cannot be factored into the conclusion.

Battery:
battery power 5000 mAh 5000 mAh
has wireless charging
Supports fast charging
charging speed 33W 50W
comes with a charger
has a removable battery
has a battery level indicator
has a rechargeable battery

Battery capacity is a non-debate: both phones carry an identical 5000 mAh cell, meaning neither has an inherent advantage in how long it lasts between charges. Similarly, both omit wireless charging and ship without a charger in the box — shared compromises that affect buyers of either device equally.

The one area where these phones part ways is charging speed. The Nothing Phone (3a) supports 50W fast charging versus the CMF's 33W. That gap is practically meaningful — at 50W, you can expect to recover a significantly larger percentage of battery in a short top-up session. For users who frequently charge in tight windows (a 20-minute break, before heading out), the Nothing's faster refill rate is a genuine daily convenience advantage.

The Nothing Phone (3a) takes a clear edge in this category, and it comes down entirely to that 50W vs 33W charging differential. Both phones start on equal footing in capacity, but the Nothing gets you back to full — or close to it — faster. It's a straightforward win with a tangible real-world payoff.

Audio:
has a socket for a 3.5 mm audio jack
has stereo speakers
has aptX
has LDAC
has aptX HD
has aptX Adaptive
has aptX Lossless
Has a radio
number of microphones 2 3

Audio is a short but decisive category. Both phones drop the 3.5mm headphone jack and share the same absence of advanced Bluetooth codecs — no aptX, no LDAC, no lossless wireless audio on either device. For wired or high-fidelity wireless listeners, neither phone offers a meaningful advantage.

Where they diverge is in speaker configuration and microphone count. The Nothing Phone (3a) features stereo speakers, while the CMF Phone 2 Pro makes do with a single speaker. Stereo output is a significant upgrade for media consumption — videos, music, and gaming all benefit from the spatial separation that a dual-speaker setup provides, producing a fuller, more immersive soundstage. The Nothing also carries 3 microphones versus the CMF's 2, which typically enables better noise cancellation and more accurate voice pickup during calls, recordings, and video.

The Nothing Phone (3a) wins this group without much contest. Its stereo speakers and additional microphone represent real, everyday advantages for anyone who consumes media or makes frequent calls without headphones. The CMF has no offsetting audio advantage in the provided data.

The connectivity foundations are largely shared — both phones support 5G, dual SIM, NFC, USB-C, Wi-Fi 6, GPS with Galileo, and an identical sensor suite covering gyroscope, accelerometer, and compass. For most users, day-to-day connectivity will feel indistinguishable between the two.

The meaningful splits come in three areas. First, the CMF Phone 2 Pro includes a microSD card slot, while the Nothing Phone (3a) does not — a significant practical advantage for users who want affordable, expandable storage. Second, the CMF edges ahead in peak download speed at 3270 Mbps versus the Nothing's 2900 Mbps, though both figures are well beyond what real-world 5G networks can currently deliver, making this difference largely theoretical. Third, the Nothing Phone (3a) carries the newer Bluetooth 5.4 against the CMF's 5.3 — a minor generational step that brings incremental improvements in connection efficiency, though not a gap that most users would notice in practice.

This group ends in a narrow edge for the CMF Phone 2 Pro, driven primarily by its expandable storage support — a feature that directly and tangibly benefits users who need more space without paying for a higher-tier model. The Nothing's Bluetooth 5.4 is a marginal counter that doesn't outweigh that practical storage flexibility.

Miscellaneous:
has a video light
Has sapphire glass display
Has a curved display
Has an e-paper display

The Miscellaneous group offers no differentiating signal whatsoever. Every data point is identical: both phones include a video light, and neither features sapphire glass, a curved display, or an e-paper display. This is a complete tie by every available measure in this category.
