Un teléfono inteligente de gama media, con un precio alrededor de 459 dólares y características premium, como los modelos insignia más recientes, resulta impresionante. Pero, ¿qué pasaría si pudieras acceder a muchas de esas funciones a un costo menor? El próximo Nothing Phone 3a ofrece una alternativa atractiva, que llega junto a su versión Pro, más cara.

Las principales diferencias entre el Nothing Phone 3a estándar y el modelo Pro se encuentran principalmente en sus cámaras. Destacadamente, el Nothing Phone 3a cuenta con una lente de zoom dedicada, una característica impresionante para un teléfono que cuesta menos de 400 dólares. Aunque el Pro puede tener una lente telefoto superior, la inclusión de una lente de zoom en un dispositivo accesible es notable.

¿Significa que unas especificaciones impresionantes garantizan automáticamente una experiencia de primera? De eso trata esta reseña, evaluando cuánto valor ofrece el Nothing Phone 3a en un dispositivo de entrada diseñado para competir con los mejores smartphones económicos por menos de 500 dólares.

review del Nothing Phone 3a: precio y disponibilidad

El Nothing Phone 3a tiene un precio de US$379 / £379 / AU$689, un poco más alto que su predecesor lanzado el año pasado por US$349. Las mejoras en el nuevo modelo justifican con creces el aumento de US$30 en el precio, aunque ofrece la misma cantidad de RAM (12 GB) y almacenamiento (256 GB). En cuanto a valor, el Phone 3a es un poco más barato que el recientemente anunciado Samsung Galaxy A36, que cuesta alrededor de US$399. También es ligeramente más caro que algunos de los últimos teléfonos de la serie Motorola G, como el Moto G Power 2025, que cuesta US$299. Sin embargo, el Nothing Phone 3a suele tener mejores especificaciones en papel, como una lente telefoto que rara vez se encuentra en teléfonos por debajo de los US$400.

La disponibilidad sigue siendo un desafío, especialmente en Estados Unidos, donde el dispositivo no se vende a través de minoristas ni operadores. En cambio, se puede adquirir mediante el programa beta de Nothing en EE.UU., que es un proceso sencillo pero limita el acceso. Las preventas del Nothing Phone 3a comienzan el 4 de marzo, y las ventas arrancan el 11 de marzo. Los clientes en el Reino Unido y Australia pueden optar por una versión más económica con 8 GB de RAM y 128 GB de almacenamiento por £329 o AU$599.

review del Nothing Phone 3a: diseño y características

¿Qué pasa con el diseño único del Nothing Phone 3a? Mi hija me preguntó cuando lo vio en mi escritorio, y si no hablas en clave adolescente, ella lo tomó como un cumplido. A diferencia de la mayoría de los teléfonos inteligentes, que suelen parecerse, el Nothing Phone 3a presenta glifos iluminados y líneas elegantes que le dan un aspecto moderno y futurista—especialmente llamativo para un dispositivo que cuesta $379.

La parte trasera del Nothing Phone 3a blanco tiene patrones de glifos llamativos que parecen sacados directamente de la caja antes de su armado. Además del blanco, los compradores en Argentina también pueden optar por una versión negra. A mi hija le parece mucho más copado el diseño, y está claro que Nothing busca atraer a un público más joven y atento a las tendencias.

En cuanto al diseño, el módulo de la cámara en el modelo 3a estándar es más simple que el arreglo circular del Nothing Pro 3a. Tiene una tira elevada con tres lentes verticales, lo que hace que el teléfono no quede completamente apoyado en una mesa. En general, el Nothing Phone 3a combina estética única con buenas características técnicas, logrando destacarse en un mercado saturado de celulares inteligentes.

You do get a pretty durable phone for the price. The Nothing Phone 3a comes with an IP64 water resistance rating, which is an improvement over the Nothing Phone 2a's IP54 rating. Still, the $399 Galaxy A36 and $299 Galaxy A26 feature IP67 ratings, meaning they can get dunked in water; the Nothing Phone 3a can survive a spray from multiple directions.

Probably my biggest quibble with the Nothing Phone 3a's design is the position of a new Essential Key, a screenshot and voice memo capture tool that supports a new software feature which we'll discuss a little bit later. The Essential Key is right below the phone's power button — indeed, it's where I would imagine the power button would mean, which means I captured a lot of screenshots when what I wanted to do was put the Nothing Phone 3a to sleep. I imagine those incidents would decrease the longer I use the phone.

reseña del Nothing Phone 3a: características de la pantalla y rendimiento

You get plenty of screen with the Nothing Phone 3a, as Nothing uses a 6.77-inch AMOLED panel with a refresh rate that ranges between 30Hz and 120Hz depending on your on-screen activity.

It also happens to be the brightest screen Nothing's ever used, according to the phone maker, which claims a peak brightness of 3,000 nits.

We didn't get close to that number when we measured the screen's brightness with a light meter. Using our standard set up, we recorded a maximum brightness of 1,194 nits, and fiddling around with different instruments, we got a reading as high as 1,370 nits.

It should be noted that most peak brightness metrics are recorded under conditions you're unlikely to experience in the real world. And the numbers we were able to measure were in line with the 1,350 nits we measured on the Pixel 8a.

The bottom line is that in daily usage, I never had a problem seeing the Nothing Phone 3a's display, even when it was bright and sunny out. And I certainly didn't need to crank up the brightness to make out details on the screen.

In its default setting, the Nothing Phone 3a captured more of the sRGB and DCI-P3 color gamuts than either the Nothing Phone 2a it's replacing or the Pixel 8a it's hoping to go up against.

The Pixel 8a's Delta-E reading of 0.24 suggests more accurate colors than the Nothing Phone 3a and its 0.29 rating, but switch to standard mode, and color accuracy improves dramatically on Nothing's device. (Numbers closer zero mean more accurate colors.)

Certainly, whether I was watching "Real Pain" or the "Fantastic Four: First Steps" trailer, everything looked colorful and bright, even from different viewing angles. I also appreciated the sound quality emanating from the stereo speakers on either end of the phone.

reseña del Nothing Phone 3a: funciones de la cámara y rendimiento

The cameras on low-cost phones aren't usually the thing I'm looking forward to trying out first since that's the area where a lot of midrange and budget devices cut corners in an effort to keep a lid on prices.

You can't accuse Nothing of that practice, though, as the Nothing Phone 3a includes a dedicated telephoto camera. No, it's not the periscope-style lens found on the Nothing Phone 3a Pro, but show me another sub-$400 phone with this kind of setup. The iPhone 16e, which costs $220 more than the 3a, only gives you one rear camera for crying out loud.

The telephoto lens — a 50MP sensor that supports a 2x optical zoom — is one of three rear cameras. Joining the party are a 50MP main lens and an 8MP ultrawide camera. A 32MP front camera handles selfie duties.

Since I just finished reviewing the Moto G Power (2025), I used that phone for camera comparisons with the Nothing Phone 3a, even though the former camera phone offers a macro sensor instead of a telephoto camera.

That said, the Power costs just $80 less than the Nothing Phone 3a, so I want to see if there's a noticeable difference thanks to Nothing's more impressive hardware and its TrueLens 3.0 photo processing engine. I'm also looking as to whether the Nothing Phone 3a's output can compare to what you'd get from the less expensive entries on our best camera phone list.

This image of a frittata looks very good when handled by the Nothing Phone 3a. You get a balance of both warm colors — as seen on the frittata itself — juxtaposed against the cooler blues of the blueberries in the background.

The text on my coffee mug looks a little softer in the Nothing Phone's shot, with the Moto G Power producing sharper edges. Still, I really can't find fault with the Nothing Phone 3a here.

When reviewing the Moto G Power, I found that it turned out decent pictures in friendly conditions, but quality dipped as the lighting dropped. You can see that happening in this public artwork shot on a cloudy, drizzly day where the Moto photo looks lost in a shadow. The Nothing Phone 3a doesn't fall in that trap, keeping everything bright and colorful, especially that oversized red Adirondack chair in the background.

I was generally impressed with how the Nothing Phone 3a performed in low lighting. Take this shot of some flags right before sunset. There's some blur around the edges of the California and U.S. flags, which were getting whipped around a bit in the wind, but the colors look good, even with the diminishing light in the sky.

Speaking of the sky, the Nothing Phone 3a does a very good job highlighting the purple clouds of the sunset, a detail that's overly dark in the Moto G Power photo.

Not every photo shot in dark conditions by the Nothing Phone 3a turned out well. The Nothing Phone's photo of some skeleton decorations in my unlit basement pumps more lighting into the sene than the Moto G Power manages.

But that's at the expense of sharpness — the skeletons have more refined edges in the Motorola photo, even if a lot of those are covered in shadow.

Creo que esa foto del sótano fue una excepción rara, ya que la mayoría de las otras fotos que tomé con el Nothing Phone 3a de noche salieron bien. Incluso la distorsión alrededor de las bombillas colgantes afuera de un bar local es mínima. En otros modos de cámara, el teléfono entrega imágenes brillantes y vivas similares a las del Nothing Phone 3a. Hay un poco de borrosidad en la toma ultra gran angular de una calle concurrida—tomada justo cuando empezó a moverse el tráfico—pero es más cálida en comparación con las imágenes del Moto G Power. Es notable que la cámara ultra gran angular del Moto G Power capture cielos azules con más contraste. Al hacer zoom 4x en una torre de reloj, la luminosidad de la esfera mejora significativamente, y no hay pérdida de claridad incluso más allá del límite de zoom óptico de 2x. Sin embargo, el modo retrato no es tan impresionante; ni el Nothing Phone 3a ni el Moto G Power lograron buenas tomas, pero la imagen del Moto captura mejor los tonos de piel naturales, mientras que la del Nothing Phone parece sobreexpuesta y demasiado pálida. El Nothing Phone 3a hace un buen trabajo reteniendo detalles como mi barba, que se pierde en el desenfoque de fondo de la toma del Moto. En general, esta es la foto más débil que tomé con el Nothing Phone. En la cámara frontal, el Nothing Phone 3a funciona mejor, con tonos de piel más cálidos en comparación con el tono demasiado rojizo del Moto G Power. Los colores del fondo son más precisos en la foto del Moto—como el marco de la ventana rojo—pero la calidad general de la imagen favorece al Nothing Phone. Claramente, el Nothing Phone 3a supera constantemente a otros teléfonos económicos en calidad de cámara. Planeo compararlo más con dispositivos como el Pixel 8a y el Galaxy A36, que son un poco más caros, para ver cómo se desempeña en pruebas directas, pero estos resultados iniciales son prometedores.

reseña del Nothing Phone 3a: rendimiento y características

En lugar de usar el chip Qualcomm Dimensity 7200 Pro del año pasado, el Nothing Phone 3a ahora cuenta con un procesador Snapdragon 7s Gen 3. Esta es una versión ligeramente menos potente del chip Snapdragon 7 estándar de Qualcomm, lo cual se refleja en las mejoras modestas de rendimiento observadas durante las pruebas con CPU en Geekbench 6. El Phone 3a obtuvo una puntuación de 1.165 en la prueba de un solo núcleo, solo aproximadamente un 5% más que su predecesor, el Phone 2a. Las puntuaciones en multi núcleo aumentaron un 27%, alcanzando los 3.288. Estos resultados superan a dispositivos como el Moto G Power (2025), que usa el chip MediaTek Dimensity 6300, pero aún están por debajo del más reciente Pixel 8a. En rendimiento gráfico, el Phone 3a mostró una mejora mínima respecto al Phone 2a, con una puntuación de 25,1 fps en la prueba Wild Life Unlimited de 3DMark, casi idéntica a los 25,5 fps del modelo anterior. Aunque algunos críticos notaron gráficos entrecortados en ciertos juegos en el Phone 2a, mi experiencia con PUBG Mobile en el 3a fue fluida. La puntuación gráfica del Phone 3a fue significativamente mejor que la del Moto G Power, que tiene 8,1 fps. En general, el Nothing Phone 3a no es una máquina potente para juegos de alta gama, lo cual se espera en un dispositivo de menos de 400 dólares. Sin embargo, durante su uso, manejó tareas cotidianas con facilidad y confiabilidad.

reseña del Nothing Phone 3a: duración de batería y rendimiento en carga

Nothing kept the same 5,000 mAh size for the Nothing Phone 3a's battery, relying on the switch to the Snapdragon silicon to help its new phone run more efficiently. And the Nothing Phone 3a is up to the challenge, posting a better result than the Nothing Phone 2a on our battery life test.

We test how long batteries can last by taking a fully charged phone, setting its display to 150 nits, and having the device surf the web over cellular until it runs out of power. The Nothing Phone 3a lasted 15 hours and 24 minutes on this test, beating out the Nothing Phone 2a's time by a modest 15 hours. In both cases, the phones' displays were set to their default adaptive refresh rate.

While the Nothing Phone 3a beat the average smartphone's time on our test by 5 hours, its result won't land it on the best phone battery life list that shows the longest-lasting devices we've tested. That's less a reflection of the Nothing Phone 3a's longevity and more on how overall phone battery life has improved dramatically overall. These days, phones need to last 16 hours on our test to land among the best of the best. The Moto G Power (2025) topped 17 hours, for example.

When it's time to charge the Nothing Phone 3a, you can count on 50W charging with a compatible charger — an improvement over the 2a's 45W charging support. After 30 minutes of charing the Nothing Phone 3a, we got a drained device to a 72% charge, which is a very good result.

reseña del Nothing Phone 3a: funciones de software y rendimiento

Nothing's new phones feature the company's Nothing OS 3.1, which is built on Android 15. As before, you get a very distinctive interface that I feel confident in saying looks like no other implementation of Android on mobile devices.

If you're a devoted Nothing phone user, there's nothing here to surprise you, but if this will be your first time seeing the dot-matrix style font and interpreting the circular icons to figure out what app you're summoning, there's a bit of a learning curve involved. Certainly Nothing OS is an acquired test, and I'm not sure that I've fully acquired it in my time with the phone.

Another new feature that will take some getting used to is the Essential Space capability that's tied to the Essential Key I mentioned earlier. Essential Space is a place for storing whatever you capture with that key, whether it's a screenshot (one press of the button) or a voice memo to capture an idea on the fly (a long press).

Remember to keep pressing that button as you're recording your thoughts, or the recording will stop. When your done with the recording, the Essential Space feature will use AI to transcribe it. AI also provides a quick summary of any screenshots you've taken with the Essential Key. And you can organize related screenshots into folders, making Essential Space a valuable research tool.

I inadvertently press that Essential Key a lot, as I noted, so I spent a lot of time in Essential Space deleting unintentionally captured screens.

I do appreciate Nothing's attempt to put AI to practical use, but I'd have to spend a lot more time with Essential Space to see if its approach to storing ideas fits into my workflow. I'd like a way to create and write a note directly in Essential Space, for example, and that capability doesn't seem to be included in this early version.

Nothing promises three years of Android updates and six years of security updates for the 3a. That security support is certainly extensive, especially for phones in this price range.

The Moto G Power (2025) has only three guaranteed years of security updates plus two Android OS updates, just for context. Of course, the newly announced Galaxy A36 and A26 have six years of software and security updates, so Nothing's not quite on the leading edge here.

reseña del Nothing Phone 3a: veredicto

The Nothing Phone 3a turns out to be as solid a device in practice as its impressive spec sheet would have you believe. For $379, you get a long-lasting phone with a unique design and a gorgeous display. The cameras produce consistently high-quality shots, and you can even zoom in on subjects with a dedicated telephoto lens — a feature a lot of competing devices can't offer.

There are nits worth picking. The Essential Space feature is promising, but needs a little bit more polish to become an integral part of your digital life. I would have liked to see bigger performance gains over the Nothing Phone 2a. And there's no ignoring the fact that, in the U.S. anyhow, it's a little more complicated getting a Nothing Phone 3a than it would be a device from more established phone makers.

On that last point, though, the Nothing Phone 3a is worth the effort to track down. It's hard to find a phone with a better value-to-price ratio, which is pretty impressive given how feature-rich a lot of midrange phones are becoming. But even those devices will have a hard time measuring up against the latest phones from Nothing.
