The iPhone Duo status icon introduces a new approach to information that has occupied the top edge of the iPhone display for nearly two decades. Instead of treating Wi-Fi, cellular signal, battery status, and other indicators as a conventional horizontal row, Apple has created a flexible circular system that sits in the corner of the foldable iPhone’s display.

Apple officially describes the feature as a “circular, flexible system” within the status bar rather than one fixed icon containing every piece of information at all times. The distinction is useful: the area can adapt according to context while consolidating status information into a smaller visual region.

It is part of a much larger rethink of iOS 27 specifically for iPhone Duo. The foldable device changes the proportions available to software, particularly when its 7.6-inch inner display is open, forcing Apple to reconsider interface elements that have traditionally stretched horizontally across an iPhone screen.

The status system is one of the smallest changes visually, but it illustrates how extensively Apple has adapted iOS around the new hardware.

iPhone Duo status icon replaces the traditional horizontal approach

Conventional iPhones distribute system information across the upper portion of the display. Cellular strength, network type, Wi-Fi connectivity, and battery status typically occupy space around the camera hardware and Dynamic Island.

iPhone Duo approaches that area differently.

Apple says its circular status system nestles into the corner of the screen and presents relevant information including Wi-Fi, cellular strength, battery status, and more. Rather than requiring a long horizontal strip, those indicators can occupy a compact area that works with the device’s unusual screen geometry.

The change is closely connected to the way iPhone Duo handles controls throughout iOS 27.

Apple has moved several interface elements to the side of the display. App navigation, toolbars, the Home Screen Dock, and some Lock Screen controls can use vertical space instead of occupying the familiar horizontal regions found on other iPhones.

The status system therefore becomes part of a vertical interface column rather than an isolated redesign.

This arrangement lets content use more of the display’s height while keeping frequently referenced system information visible. It also creates a consistent location for status details as users change how they hold or fold the device.

A flexible status system suits a foldable iPhone

A foldable phone presents an interface problem that a traditional slab-shaped iPhone does not have.

iPhone Duo can operate through its 5.4-inch outer display or its substantially larger 7.6-inch inner screen. The device can be opened completely, partially folded, rotated, or positioned like a small book.

A static status bar designed around one screen size and orientation would be less effective across those configurations.

Apple instead built iOS 27 so that interface elements can move as the physical device changes. Content reacts to folding, controls relocate, and layouts adjust around the hinge and available screen area.

Apple’s developer guidance provides additional detail about this philosophy. On iPhone Duo, navigation and toolbar controls share vertical space with system elements such as the status bar and Live Activities. When available room becomes limited, application controls can collapse into an overflow menu.

That makes the circular status area part of an adaptive system rather than a cosmetic flourish.

Developers do not need to manually reproduce the status treatment inside their apps. Apple’s standard interface frameworks handle much of the adaptation, especially when applications use native navigation, toolbar, and tab-bar components.

Dynamic Island also moves to the side

The status area is not the only familiar piece of iPhone interface that changes position on iPhone Duo.

Apple has redesigned Dynamic Island so that it can sit vertically along the side of both the outer and inner displays. It can expand from that position to present alerts and Live Activities.

The relationship between Dynamic Island and the new circular status system is particularly interesting because Apple now has two dynamic interface areas operating along the same side of the screen.

One communicates persistent device information such as network and battery status. The other handles temporary activity, alerts, and live information.

Apple’s developer documentation refers to this section as shared vertical space. Application controls may also occupy it, meaning iOS has to continuously decide how much room is available and which elements deserve priority.

That is a major departure from the long-standing assumption that the upper corners of an iPhone screen simply contain a predictable row of small status symbols.

On Duo, those regions have become active parts of the interface layout.

Wi-Fi, cellular, and battery remain immediately recognizable

Consolidating status information creates a design challenge: efficiency cannot come at the expense of readability.

Users have spent years learning the meanings of Apple’s individual status symbols. Cellular bars indicate signal strength, the Wi-Fi symbol communicates wireless connectivity, and the battery icon provides an immediate indication of remaining power.

Apple has not discarded those familiar concepts.

Instead, the circular system changes how and where information is presented. The familiar status categories remain present while the container around them becomes more adaptable.

This is particularly useful on a device with two displays. Users should not need to relearn the meaning of basic connectivity information when moving from the outer screen to the inner display.

The same reasoning applies when iPhone Duo changes orientation. Apple can reorganize the status area without changing the fundamental visual vocabulary behind Wi-Fi, cellular, or battery information.

iPhone Duo pushes the status bar beyond a fixed strip

The new design suggests a different direction for one of the oldest pieces of smartphone interface.

Status bars traditionally behave like reserved strips of screen space. Applications work around them, and their icons occupy predictable positions regardless of what is happening elsewhere.

iPhone Duo turns that space into something more fluid.

The circular system can coexist with a vertical Dynamic Island, changing application controls, Live Activities, and layouts that respond to the physical position of the foldable display. It becomes another component that iOS can arrange rather than a fixed row placed permanently along an edge.

There is no indication that Apple plans to bring the same circular status treatment unchanged to conventional iPhones. Its current implementation is specifically tied to iPhone Duo and the interface requirements created by the foldable hardware.

Still, the design provides a glimpse at how Apple can rethink even deeply established iPhone conventions when the shape of the device changes. When iPhone Duo reaches customers on October 23, the small circular area in the corner will be one of the most immediately visible examples: cellular strength, Wi-Fi, battery information, and other system details occupying a shared adaptive space instead of stretching across the display.

O aplicativo de mensagens Signal, conhecido pelo seu grande enfoque em segurança e privacidade, anunciou hoje que está expandindo o suporte a dispositivos vinculados — permitindo agora usar uma mesma conta em mais de um smartphone, tanto no iOS quanto no Android.

No sistema operacional da Apple, o suporte como dispositivo vinculado é uma adaptação do que já era possível fazer com iPads desde 2019. Basicamente, o Signal modificou a mesma interface já existente para que ela funcionasse bem em telas menores, sem perder a compatibilidade com o iPadOS.

No Signal, ao configurar a vinculação de um novo dispositivo, o usuário pode escolher entre duas opções: transferir todo o histórico de conversas e mídias armazenadas dos últimos 45 dias ou simplesmente começar do zero — nesse caso, o novo aparelho recebe apenas novas mensagens.

A possibilidade de sincronizar o histórico de conversas, vale recordar, estreou no aplicativo no ano passado. Diferentemente de alguns mensageiros, todo o processo é criptografado de ponta a ponta — ou seja: os servidores do Signal não têm acesso ao conteúdo das mensagens.

Além de possibilitar definir outros smartphones e tablets como dispositivos vinculados, o Signal também permite (há bastante tempo) fazer o mesmo com computadores — seja no macOS, Windows ou Linux.

When the brain tracks time, it must decide whether its regions should rely on a shared timing signal or tack time separately. A recent study in Nature Communications provides evidence that the brain uses both approaches, switching between them depending on the situation.

A group at the Institute of Science Tokyo simultaneously measured the activity of thousands of neurons in two mouse brain regions and found that the areas sometimes shared timing information but maintained more independent representations at other times. The researchers, led by Associate Professor Riichiro Hira, maintained that this flexibility enables the brain to remain stable as it adapts to changing requirements.

A Task Built to Catch the Brain Switching Modes

Hira’s team created a task to highlight this timing mystery. They trained mice to expect rewards at intervals that switched between 6 and 12 seconds, without any break to mark the end of one trial and the start of the next. Since there was no pause, the mice had to keep updating their internal sense of time throughout the experiment, instead of resetting their mental stopwatch for each new trial.

The mice eventually figured out the pattern. At first they expected a reward every six seconds even if the time they had to wait was longer than this, but by the end of the training session, their behavior indicated that they had learned to anticipate both reward intervals. This showed that the mice were capable of keeping track of both durations and of predicting which one would come next.

While the mice performed the task, the researchers recorded activity in their secondary motor cortex and the posterior parietal cortex using wide-field two-photon calcium imaging. Both regions play key roles in planning, prediction, and working memory.

Two Regions, Two Kinds of Mistakes

The neurons fired in sequence in each brain area, with different cells becoming active at different times. This sequence showed that each region was monitoring the passage of time.

The researchers also identified two kinds of errors in the neural activity. In some cases, both areas made the same mistake when assessing the passage of time. These coherent errors suggested that both regions sometimes shared the same timing drift. In other instances, only one region was inaccurate while the other remained correct. These independent errors suggested that one region could temporarily maintain a different timing representation from the other. Independent errors were more frequent than coherent ones, and this ratio remained the same in all the mice examined.

If the brain regions were just randomly out of sync, you’d expect the ratio to change. However, it didn’t, which suggests that the brain has a built-in way to balance working together and working independently.

Modeling the Switch Between Coherence and Independence

To identify this mechanism, the team built a computational model with two recurrent neural networks linked by sparse, long-range connections and exposed to the same background noise. The model produced the same 2-to-1 ratio of independent to coherent errors seen in the mice.

The model also discovered that the limited connections between the networks tended to cause them to become synchronized, while the common noise caused them to move in separate directions. Hira provided an explanation of the interaction saying, “We found sparse inter-regional connectivity promotes synchronization between the two regions, whereas widespread fluctuations prevent complete synchronization, allowing each region to preserve its own temporal representation.” Neither force takes precedence; instead, a compromise is reached which allows communication between the regions.

The findings challenge the idea that brain regions rely on a single synchronized timing system. It indicates that the brain can adjust how different parts are coordinated, rather than just turning that coordination on or off.

What a Flexible Clock Could Mean for the Brain

Hira’s team believes that there are implications beyond simple timing circuits. “In the future, our results may contribute to a better understanding of cognition, neurological disorders involving disrupted inter-regional coordination, and the development of brain-inspired artificial intelligence and robotic control systems that combine stability with flexibility,” said Hira.

This last idea may prove most important in the years ahead. Engineers building AI and robotic systems face a similar challenge: how to let separate parts work on their own when needed, yet still come back into sync. The mouse brain shows that sparse connections and shared background fluctuations can achieve this balance. This could point to a design principle that even applies to systems with no biological components.
