Essas menções tratam-se de mensagens relacionadas à saúde do componente e chamam a atenção justamente por estarem no plural, já que os smartphones da Maçã contam com apenas uma célula de bateria em suas entranhas.
Foram identificadas, ao todo, três mensagens, as quais muito provavelmente serão exibidas em momentos distintos da vida útil dessas baterias. A primeira (em tradução livre), por exemplo, deverá ser exibida quando as células ainda são relativamente novas:
As baterias deste iPhone estão apresentando o desempenho esperado.
Já a segunda provavelmente entrará em cena assim que o desgaste da bateria começar a afetar a performance do “iPhone Ultra”:
A saúde das baterias deste iPhone se degradou significativamente. Um Centro de Serviço Autorizado Apple pode substituir as baterias para restaurar o desempenho e a capacidade totais.
A terceira, por fim, alertará usuários sobre componentes fabricados por terceiros:
A saúde das baterias deste iPhone sofreu uma degradação significativa, e não foi possível verificar se uma delas é uma bateria original da Apple. Um Centro de Serviço Autorizado Apple pode substituir as baterias para restaurar o desempenho e a capacidade totais.
O iOS, é claro, já exibe mensagens parecidas no seção “Saúde da Bateria e Carregamento” do menu “Bateria”, presente no app Ajustes (Settings), de modo que a novidade aqui é mesmo a linguagem adaptada para um dispositivo com mais de uma bateria. Como o “iPhone Ultra” provavelmente será dividido em duas partes, é bem possível estejamos falando de um par de células.
Há um tempo, mostramos por aqui como é simples aumentar a resolução de uma imagem contida em um quadro do Freeform, graças à função Super-resolução (Super Resolution) do Apple Creator Studio.
O que muita gente não sabe é que ela também pode ser usada em imagens que tiverem sido anexadas em documentos do Pages, em planilhas do Numbers ou em apresentações do Keynote.
O Apple Creator Studio desbloqueia vários recursos bacanas de aplicativos já conhecidos pelos usuários de dispositivos da Maçã.
Dentre os exemplos, estão os apps Pages, Numbers e Keynote. Com eles, assinantes do Creator Studio podem gerar imagens e adicioná-las aos seus documentos, planilhas e apresentações de slides.
Com o Pixelmator Pro e uma assinatura do Apple Creator Studio, o processo de edição de imagens fica muito mais fácil e eficaz, graças às ferramentas avançadas disponibilizadas.
Uma dessas ferramentas é a Super resolução (Super Resolution). Com ela, é possível ampliar qualquer foto, ao mesmo tempo que se tenta preservar a nitidez e os detalhes.

“O armazenamento do iCloud está quase cheio”. Se você usa iPhone, aposto que leu essa frase nesta semana. Talvez hoje. Ela aparece nos Ajustes, aparece por notificação, aparece quando o backup falha de madrugada… e não desiste nunca. Não é um bug. É, possivelmente, o vendedor mais eficiente que a Apple já contratou.
Nas últimas semanas, escrevi aqui duas matérias medindo produtos da Apple numa moeda que todo mundo entende na pele: horas de trabalho. Vimos quanto custa um Mac depois dos aumentos e quanto custou cada geração de iPhone desde 2007. Mas hardware você paga uma vez e o assunto morre; assinatura, não. Assinatura é um pedágio silencioso: poucos reais por mês, para sempre. E ninguém de fato se dá ao trabalho de fazer essa conta — então eu resolvi fazer.
Os mesmos 5GB desde 2011
Antes dos números, um pouco de contexto. Quando o iCloud nasceu, em outubro de 2011, a Apple deu 5GB gratuitos para cada conta. Era a época do iPhone 4s, de câmera de 8 megapixels e fotos de uns 2,5MB cada. Dava para viver um bom tempo dentro daquele limite.
Quase 15 anos depois, os 5GB continuam exatamente os mesmos. Só que o mundo ao redor deles mudou de tamanho: o iPhone 17 tira fotos de 48MP, grava 4K a 60 quadros — cerca de 400MB por minuto — e sai de fábrica com 256GB. Ou seja, a Apple vende um aparelho com 256GB e dá uma nuvem que corresponde a 2% disso. Um backup básico, sozinho, já não cabe. A caixa ficou pequena de propósito ou só ficou pequena? Guarde essa pergunta.
Quem não aguenta o aviso assina o iCloud+. No Brasil, depois do reajuste de até 33% em 2025, as mensalidades saem por R$5,90 (50GB), R$19,90 (200GB), R$66,90 (2TB) e vão até R$399,90 (12TB).
A conta em horas, plano a plano
A régua é a mesma das matérias anteriores: salário mínimo por hora no Brasil (R$8,50), nos Estados Unidos (piso federal de US$7,25), no Canadá (C$17,60, em Ontário) e em Portugal (5,31€). Cada célula mostra quanto tempo de trabalho um mês de assinatura consome.

Preços oficiais da Apple em julho de 2026, sempre no plano mensal.
À primeira vista, parece barato — e é justamente assim que uma assinatura funciona. O plano de 50GB custa 42 minutos de trabalho por mês. Quem reclamaria? Mas suba na tabela: o plano de 2TB, o mais comum para quem tem família ou anos de fotos acumuladas, consome quase um dia inteiro de trabalho por mês de um brasileiro de salário mínimo. O mesmo plano custa 44 minutos para um canadense. E o de 12TB beira o surreal: 47 horas mensais — mais de uma semana de expediente, todo mês, só para guardar arquivos.
Vale a comparação com o hardware: nas matérias anteriores, o brasileiro trabalhava de 8 a 12 vezes mais que o americano pelo mesmo iPhone ou iPad. Nos serviços, a distância é menor — cerca de 6 vezes no plano de 2TB —, mas segue aí, firme e forte. Contra o Canadá, a proporção volta às mesmas 10 vezes de sempre. E Portugal repete o papel de meio-termo que já apareceu na conta do hardware: 1h53min pelos mesmos 2TB, 4x menos esforço que o brasileiro — confortável perto de nós, longe do sossego canadense.
O pedágio que nunca acaba
Agora, o detalhe que muda tudo: essa conta não fecha nunca. O iPad de 706 horas dói uma vez; o iCloud cobra todo mês, até o fim dos tempos — ou das suas fotos, o que vier primeiro.
Um ano de iCloud+ de 2TB custa R$802,80 — 94 horas de trabalho, meio mês de expediente por ano. Em 10 anos, são mais de 900 horas: território de iPhone 17, que calculei em 1.006 horas na matéria anterior. Ou seja, guardar as fotos por uma década custa quase o mesmo esforço que comprar o telefone que as tirou.
E tem o degrau seguinte, claro. O Apple One Individual (R$42,90) leva 5 horas mensais de trabalho; o Premium (R$99,90), quase 12 horas — cerca de 140 horas por ano, ¾ de um mês de trabalho anual em assinatura. No fim das contas, o brasileiro de salário mínimo que assina o pacote completo da Apple dedica praticamente um mês do ano só para manter os serviços da Maçã rodando.
Por que a caixa não cresce
Aqui entra o olhar de produto, área em que trabalho há mais de 20 anos. Aquele aviso de armazenamento não é um acidente de percurso: é um funil de conversão dos bons! Ele aparece no momento de maior dor (backup falhou, foto não salvou), oferece a solução a um toque de distância e custa “só” R$5,90. Nenhum vendedor de loja chega perto dessa taxa de conversão.
E o incentivo para manter os 5GB congelados é gigante. Os serviços renderam à Apple US$109,2 bilhões no ano fiscal de 2025, com margem bruta de 75% — o dobro da margem do hardware. Cada pessoa que cede ao aviso vira receita recorrente, previsível e baratíssima de servir. Se os 5GB gratuitos virassem 50GB amanhã, quantos milhões de assinaturas de entrada evaporariam? A Apple sabe a resposta melhor do que ninguém. Tanto que Google (15GB) e Microsoft (5GB, mas com Office no pacote) jogam jogos parecidos — a Apple só joga com a caixa mais apertada do mercado.
Sejamos justos num ponto: nuvem custa dinheiro de verdade (data center, energia, redundância) e o iCloud+ entrega junto recursos como o Retransmissão Privada (Private Relay) e o Ocultar Meu E-mail (Hide My Email). Não é um produto ruim; eu mesmo assino e não pretendo cancelar. O problema não é o plano pago existir, é a versão gratuita ter sido desenhada para não ser suficiente — em 2011, ela era.
No fim, é uma escolha de modelo de negócio — e das mais bem executadas. Só acho saudável que a gente a chame pelo nome. Quando o aviso aparecer de novo aí no seu iPhone — e ele vai aparecer —, lembre que aqueles 42 minutos de trabalho por mês não foram um acaso: foram desenhados, testados e otimizados para esse exato momento. A Apple não vende mais só o telefone. Vende o lugar onde a sua vida digital mora — e cobra o aluguel em dia.
I downloaded all my photos from Google photos so I can move them to the Apple Photos app.. So now I have a bunch of folders that have 100 or more photos in them but they also have 100 or more text files that end in json.
Deleting the text files from each folder manually in the Finder is gonna take forever. Is there an easy way to get rid of these text files out of each folder while keeping the photos? Thanks.

Recently Time Machine takes forever to back to my 1TB external. There's still about 320GB of space, so I am not sure why this is happening.
I went ahead and deleted old backups that I can see in the TM folders. These are from ten years ago and not needed anymore. Even now, however, it seem to be taking too much time to backup.
The last backup said it needs 5 hours or more to complete, so I cancelled it when it was at 16 percent.

Ever since I updated to Tahoe 26.5.2 a few days ago, I've had an inordinate number of pages that "reloaded because a problem occurred". Prior to that, there were a couple of websites that were prone to this, but now it's almost every website I go to.
Future spacecraft may travel farther by drawing momentum from planets, sunlight, and the solar wind instead of onboard fuel. Every conventional rocket faces the same problem: it must carry the material that propels it. Since Konstantin Tsiolkovsky described the rocket equation in 1903, spacecraft have burned fuel and expelled it backward to move forward under [...]
By analyzing nickel isotopes preserved in the 66-million-year-old debris left by the Chicxulub impact, researchers conclude that the asteroid responsible for Earth’s last mass extinction most likely belonged to an exceptionally rare class of primitive meteorites called carbonaceous chondrites of the Ornans type (CO chondrites).
For centuries, ancient seafarers have told tales of fabled lost lands. They have been known by many names—Ultima Thule, Hy-Brasil, the Fortunate Isles, and of course, the legendary lost city of Atlantis.
Now, scientists say Earth’s hidden plumbing system may be feeding one of its strangest ecosystems—an area on the Atlantic seafloor that conjures images of such legendary landscapes lost to time and memory.
Known as the Lost City hydrothermal field, this ancient Atlantic oddity is doing more than just broadening our view on how extremophiles thrive in some of our planet’s least hospitable environments: it offers a potential model for how extraterrestrial life may thrive elsewhere in our solar system.
In a recent paper published in Geophysics, Geochemistry, and Geosystems, an international team of researchers finally discovered the system behind these hydrogen- and methane-rich alkaline hot springs that feed the Lost City ecosystem.
The white carbonate chimneys that emit these gases provide an alternative to sunlight as the Lost City’s primary energy source, allowing life to thrive in a challenging deep ocean environment.

Searching Near The Lost City
Those precious nutrients coming from these vents were created by underground reactions. It turns out that the water feeding the Lost City is likely part of a larger underground system, where extreme processes imbue the liquid with essential nutrients.
The discovery came from nearly a mile below the Atlantis Massif, a large block of Earth’s crust that forms an underwater mountain range. This dome-shaped region stretches for 10 miles and rises 14,000 feet above the ocean floor.
Above, a map shows the location of the Lost City on the Atlantis Massif (Image Credit: NOAA)
Geologists believe this formation originated between 1.5 and 2 million years ago, as tectonic plate movement pulled it out from beneath the Mid-Atlantic Ridge, forming a new feature on the ocean floor.
From aboard the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES) ship Resolution, scientists drilled their 4,160-foot-deep hole about 2,600 feet north of the Lost City. They were intrigued to find that the water recovered from the hole had a chemical composition extremely similar to that of water emerging from the Lost City vents.
Beneath The Ocean Floor
From their drill site, they pumped water from varying depths up to the surface for examination.
Roughly the first 1,500 feet consisted primarily of seawater and freshwater from the drilling process, yet at lower depths, they found water that had risen from beneath the rock. At the deepest depths, up to 80% of the sample came from these subterranean regions.
Their detailed analyses revealed that the water had reacted with the surrounding minerals to gain calcium while losing magnesium, a reaction that would require prolonged exposure to rocks at a temperature of at least 572°F. Despite this finding, the hole was much cooler when the team took their samples.
Typically, a water-rock reaction with gabbroic and ultramafic rock would produce such results that are high in calcium, yet with no magnesium. Other components, such as lithium, rubidium, cesium, and strontium, were found in the water at both the bore site and Lost City.

The findings are consequential for providing the first direct evidence of this extremely hot water circulating beneath the Atlantis Massif through gabbroic and ultramafic rock. In this hidden plumbing system, seawater reaches deep within oceanic plates, providing energy to these deep-sea environments and potentially supporting their microbial life.
Feeding The Lost City
As researchers have now demonstrated that hydrogen-enriched water can naturally form deep within the Earth through rock reactions, researchers say there are major implications for our understanding of the Earth and beyond.
For one, it adds a new element to Earth’s energy cycles, explaining how life persists under such difficult, dark conditions. Secondly, it offers intriguing new ideas about how life might persist in extraterrestrial environments, as humans continue to search for it elsewhere in the cosmos. The strange conditions of the Lost City ecosystem are thought to be a potential model for how life could persist in the global oceans of ice-covered worlds such as Jupiter’s moon Europa or Saturn’s moon Enceladus.
However, some uncertainty about the samples does remain. Seawater, freshwater, and drilling contaminants were present in the samples, and the exact proportions attributable to gabbro or ultramafic rock are unknown. Also, while this is evidence for an underground connection between the borehole and the Lost City chimneys, it is not conclusive proof that they are connected.
Plans are already underway to return once the borehole has stabilized to collect pristine samples that will allow researchers to answer questions about where and how these reactions occur, as well as the amount of energy they add to the water. From the most inhospitable regions on Earth to the quest for organisms among the stars, the research underway deep within our oceans is providing new answers to how such life persists.

A new analysis suggests the four sub-Earth exoplanets orbiting Barnard’s star -- the Sun’s nearest single-star neighbor -- are likely packed with the deep-Earth mineral periclase, stripped of their atmospheres and far too hostile to support life.
If you still picture Mars as a monotonous red desert, it may be time for an update.
The European Space Agency's Mars Express orbiter has been capturing some of the Red Planet's most surreal landscapes, and its latest images reveal a sprawling field that looks like molten metal frozen across the floor of an ancient Mars crater.
The shimmering "waves" aren't metal at all, however. They are dark sand dunes dusted with seasonal frost, much of it carbon dioxide, or "dry ice," that settles on the surface during Martian winters, giving the dunes their uncanny chrome-like sheen, according to ESA.
The rest is a trick of light and contrast. Because the dark sand absorbs light and the white frost reflects it, the interplay transforms the landscape into something that looks more like a scene from a sci-fi movie than a windswept Martian plain.

Over thousands of years, Martian winds have sculpted this volcanic sand into dunes that now ripple through the floor of Kaiser Crater, a 129-mile-wide (207-kilometer-wide) impact basin in the planet's southern highlands. The bowl-shaped crater acts as a giant sand trap that prevents the sand from escaping, according to NASA.
The dunes themselves are darker than much of Mars' surface because they are made of fine, basaltic sand rich in volcanic minerals such as pyroxene and olivine, rather than the iron-oxide dust that gives the planet its familiar rusty-red appearance and its famous moniker, the Red Planet.
Because the crater floor remains visible between the ridges, scientists think there is a relatively limited sand supply shaping the field. Still, these ripples of sand are massive, extending for several kilometers and towering more than 100 meters (320 feet) above the surrounding terrain.
The landscape isn't just visually dramatic, it also preserves clues to a time when Mars was a very different world.
Today, Mars is wrapped in an atmosphere little more than a thin veil that is 100 times thinner than Earth's and slowly leaking into space. That makes it harder for winds to lift and transport sand than it is on our own planet. Yet the soaring dunes inside Kaiser Crater show that Martian winds have nonetheless been powerful enough to sculpt vast landscapes over time, perhaps during a period when the Martian atmosphere was thicker a few billion years ago.
The new image adds to a growing collection of striking Martian scenes captured by Mars Express, which has been orbiting the Red Planet since 2003. Just last month, the probe tracked a frenetic cluster of 30 dust devils swirling through the canyons of Mamers Valles, also in the northern hemisphere.
Over the spring and summer, the orbiter similarly spotlighted the planet's vast and complex geological history, from Shalbatana Vallis — carved by groundwater floods about 3.5 billion years ago into winding valleys that span the length of Italy — to a massive blanket of dark volcanic ash elsewhere on the world that has spread across a large chunk of the terrain over just the last 50 years, having either been redistributed by Martian winds or exposed as the overlying dust was blown away.
However desolate Mars may appear from afar, there is certainly no shortage of activity on its surface — or discoveries still waiting to be made.
Smoke from wildfires across Canada travels across both Canada and the U.S. in this satellite image captured by NOAA-21 on July 14, 2026. (Image credit: NASA Earth Observatory/Lauren Dauphin)
The wildfires tearing across Canada are so extreme that the smoke billowing upward can be seen from space.
What is it?
Over 850 wildfires are currently devastating Canada, as reported by theCanadian Interagency Forest Fire Center. The fires are spreading across Manitoba, Saskatchewan and Ontario; most remain completely uncontrolled.
In addition to the immense destruction caused by the fires themselves, the smoke from these fires is causing serious concerns about dangerously poor air quality all across Canada and even in the northeastern United States. As far as New York, the air quality on Thursday (July 16) was labeled "very unhealthy" after the state activated emergency air quality protocols.
The smoke is so expansive it's clearly visible in this image captured on July 14 from Earth orbit.
Why is it noteworthy?
Studying wildfires and wildfire smoke from orbit can give us a bigger picture view of these catastrophic event. This data is important for disaster relief in the short term — but also in the long-term. With climate change continuing to progress due to human activities like burning coal for cheap power, we can expect natural disasters to worsen. Among the many effects of climate change, this includes longer and more intense wildfire seasons, especially in regions that are already susceptible to fire such as these regions across Canada.
The new image was captured by the NOAA-21 satellite with the instrument VIIRS (Visible Infrared Imagine Radiometer Suite). You can see massive plumes of smoke over southeastern Canada treading into the northeastern U.S. Thick smoke covers swaths of Canada's landscape and wisps of smoke trail all the way down through New York and across the U.S.
Most of this smoke, at least the smoke we can see in this satellite image, is coming from wildfires in northwestern Ontario. As the wildfires continue to burn, satellites like NOAA-21 will be keeping watch.
