Apple will reportedly use this tool inside the iPhone 17 Pro models to beat the heat
First, you should know that currently, Apple uses Graphene sheets to draw heat away from the A18/A18 Pro chipsets on the iPhone 16 series and move it toward cooler parts of the phone. Apple also replaced the foil covering the batteries powering the iPhone 15 line with a metal covering for the cells used to power the iPhone 16 series. This is another way to draw heat away from the battery and spread it out through the inside of the phone. Apple also tends to rely on the metal and glass body of the phone itself to cool it down internally.

When the device heats up, the liquid in the chamber evaporates. The vapor moves across the device returning to a liquid state when it is cooler inside the phone. This constant cycle allows temperatures to drop quickly allowing the device to cool down without having to resort to throttling the performance of the chipsets. Majin Bu, who has a mixed record when it comes to accuracy, says that the iPhone 17 Pro and iPhone 17 Pro Max both face a higher degree of thermal issues. That's because the two models feature a more advanced and powerful application processor and display features. The non Pro models, the iPhone 17 and iPhone 17 Air, will use traditional methods to dissipate the heat.
If the vapor chamber does its job, users should notice the iPhone 17 Pro and iPhone 17 Pro Max remaining cool to the touch even during extended use. For example, a long video game playing session would typically heat up an iPhone.

This underrated Google app just got its Material 3 Expressive makeover
Google has been busy, busy, busy giving its Android apps Material 3 Expressive makeovers. I have to say that, for the most part, these makeovers have been well changes made to the UIs of these apps have made them easier to use, more useful, and in many cases, the Dynamic Color feature brings in the main color theme from your phone's wallpaper improving the look of the app. The Google Contacts app is now getting its makeover. The update is rolling out now via the Google Play Store. Material 3 Expressive makeover of the Google Contacts app. | Image credit-PhoneArena The new look Contacts app has a bottom bar that is shorter, although the three tabs, Contacts, Highlights, and Organize, remain the same. Pressing on any of the three tabs reveals a major UI improvement as each name is now in an easier to see rounded container, making it easier to see exactly which name you are clicking on. Previously, there was no clear-cut separation between the names of the contacts. Each individual contact also gets a card with a giant avatar and the name of the contact underneath. Directly below the contact's name are four options: The big change to this card with the makeover is that the names of these four actions are now placed inside a pill-shaped field. Previously, the four actions were placed inside of a simple circle. The new look has been found on version 4.6.1.x of the Google Contacts app. To see which version of the app is running on your Android phone, tap on Settings > Apps > See all xxx apps . Scroll down to Contacts and tap on it to visit the Google Contacts App info page. Scroll down to the bottom of the page to see the version of the app installed on your device. My Pixel 6 Pro running Android 16 QPR1 beta 3.1 does have the refreshed version of the Contacts app. The Google Contact card is also given a little makeover. | Image credit-PhoneArena The Material 3 Expressive refresh for Google Contacts might not be the most jarring. Nor is the Contacts app the most heavily used app on your handset. Still, with all of this in mind, Google still worked hard on this makeover; it is enough of an improvement to make the Contacts app more useful and easier for users to employ.

China introduces its first domestically made e-beam lithography machine
We've often said that the inability of Chinese foundries and tech manufacturers to obtain Extreme Ultraviolet (EUV) lithography machines is the big reason why China is so far behind in the chips race. Thanks to U.S. and Dutch officials, the one company that makes advanced lithography gear, Dutch firm ASML, cannot ship the latest EUV lithography equipment to China. However, less advanced Deep Ultraviolet (DUV) lithography machines, using older technology, can still be shipped to China. This is important because EUV machines are needed to manufacture chips under 7nm. Foundries like TSMC and Samsung Foundry will be mass producing chips using their 2nm process nodes this year. Lower process node numbers mean that the transistors used are smaller, allowing more to fit into a small space inside a chip. This number is called the Transistor Density and is usually shown as millions or billions of transistors per square millimeter. The higher the transistor density, the more powerful and energy-efficient a chip is. The lithography machine is used to transfer circuitry patterns onto the silicon wafers that serve as the foundation of the chips manufactured by foundries. Deep Ultraviolet (DUV) light has a wavelength of 193 nanometers. EUV, however, uses light with a wavelength of just 13.5 nanometers, which is about 14 times shorter. This shorter wavelength allows EUVs to etch the fine patterns needed for today's intricate chip designs. -Hangzhou Daily But the Chinese have built their first e-beam lithography machine, which they have titled Xizhi. It was created at Zhejiang University in Hangzhou and uses focused electron beams to etch the circuitry patterns on the silicon wafers. The downside is that e-beam lithography cannot produce chips at a large scale like DUV and EUV machines can. But for China, it's any port in a storm when it comes to lithography, and the e-beam lithography works great during the testing phase of production. An ASML built Extreme Ultraviolet lithography machine. | Image credit-ASML A local newspaper, Hangzhou Daily , said on Thursday, "Due to export controls, such equipment has long been out of reach for leading domestic research institutions, including the University of Science and Technology of China and Zhejiang Lab. The delivery of Xizhi is expected to help break this impasse." Xizhi can etch circuit lines as narrow as 8 nm, with a positioning accuracy of 0.6nm. This meets international standards. Discussions with Chinese companies and research institutes interested in Xizhi have begun. The domestically produced e-beam lithography machine is cheaper than similar devices imported into China. This is just the beginning of China's attempt to bypass U.S. restrictions by producing its own chipmaking equipment. There are reports that Huawei has been working on building its own EUV machine. Reportedly, Huawei has been testing a trial EUV machine at its factory in Dongguan. Supposedly, Huawei will aim for trial production later this year with mass production expected to take place in 2026. Should Huawei be able to create an EUV machine, it would be a big deal for China in general and Huawei in particular. It could allow Huawei and China's largest foundry, SMIC, to produce cutting-edge chips that might be able to compete with the silicon designed by U.S. chip design heavyweights like Apple, Qualcomm, and Nvidia. Before the U.S. implemented the sanctions preventing Huawei from obtaining cutting-edge chips, the Chinese manufacturer's HiSillicon chip design unit was TSMC's second-largest customer after Apple. At that time, HiSilicon and thus Huawei had access to TSMC's most cutting-edge process nodes. In fact, the last chip TSMC produced for HiSilicon before U.S. sanctions kicked in was the Kirin 9000 AP. Built using TSMC's 5nm process node, this was the SoC used to power the Huawei Mate 40 series in 2020. After the sanctions went into effect, Qualcomm was given a license from the U.S. Commerce Department allowing it to ship 4G Snapdragon chips to Huawei. In 2023, Huawei stunned the industry by releasing the Mate 60 series powered by the Kirin 9000S. Produced by SMIC, the SoC was built using the foundry's 7nm process node and brought 5G support back to Huawei's flagship phones.

Apple accidentally leaks some of its upcoming products
Apple does not like leaks. Its lawsuit against FPT's Jon Prosser, accused by the tech giant of getting access to a developmental iPhone 17 model owned by an Apple employee, makes this crystal clear. But the reason for Apple's anger might not be as clear. You see, Apple apparently wants to get into the "Apple Leaks" business itself and hopes to shut down a competitor (Prosser). Apple itself just accidentally leaked several new products and while this paragraph was written with tongue-in-cheek, the rest of this story is true. According to the report, Apple slipped up and included code used to identify hardware in software code that linked to several unannounced products. One of the products is a new HomePod mini carrying a codename of B525. This tracks perfectly since the current HomePod mini sports a codename of B520. The new HomePod mini will use the same T8310 microarchitecture deployed on the Apple Watch. The Apple HomePod mini, released in 2020. | Image credit-Apple The Apple Watch Series 9 and Series 10 both use the T8310 core architecture. It is also expected to be used with the S11 chip that will run the Apple Watch Series 11, scheduled to be unveiled next month. This indicates that a new chip will replace the S5-class chip that is used with the currently offered HomePod mini model that was released in 2020. The new chip will reportedly have a 64-bit dual-core CPU based on the A16 application processor (AP). It will also feature a four-core Neural Engine, which is something that the chip inside the current HomePod mini doesn't have. The HomePod mini 2 could be released this year anytime between next month and the end of 2025. Among the unannounced new products that Apple leaked is a new Apple TV powered by the same A17 Pro AP that powers the iPhone 15 Pro and iPhone 15 Pro Max. The updated silicon would be a nice improvement from the A15 Bionic currently found in the current Apple TV product. The new chipset will bring Apple Intelligence support to Apple TV and will also allow the product to run console-tier games with the quality graphics such games deserve. The company is supposedly testing its own Bluetooth/Wi-Fi chip to use with the product. The new Apple TV unit could be released as soon as next month at the earliest; it is expected to see the light of day sometime this year. A new iPad mini (J510/J511) was one of the products leaked by Apple. It is expected to feature the powerful new A19 Pro AP which will be the silicon inside the upcoming iPhone 17 Pro and iPhone 17 Pro Max. The last iPad mini was released last October, employing the A17 Pro. Apple is supposed to be working on a new iPad mini with an OLED display for 2026 or possibly 2027. This could be the model leaked by Apple. The A19 Pro AP that could run this device has more GPU cores than the A19 SoC. There could be a binned version of the A19 Pro with just one less GPU core, which might be found inside the upcoming ultra-slim iPhone 17 Air. A binned chip is one that was not perfectly produced and, as a result, it was placed in one of various bins based on its flaws. This is done so that chips not perfectly produced don't have to be thrown out and can be employed. A new entry-level iPad (J581/J582) was also leaked by Apple, and the product will get a chip boost from the A16 used on the current entry-level Apple tablet to the A18. Expected next spring, the new low-end iPad should support Apple Intelligence and feature a 16-core Neural Engine. The chipset might be new, but the design of the tablet will reportedly stay the same. The new Apple Watch Series 11 , Ultra 3, and Watch SE 3 were included in the leak, and Apple is expected to use the S11 System in Package (SiP) chip to power its upcoming timepieces. With the same T8310 architecture used with the S9 and S10 SiP, the S11 could carry two performance cores, a 64‑bit dual‑core CPU, and a 4‑core Neural Engine. Other devices accidentally leaked by Apple include: Vision Pro 2-powered by M5 chip, replacing the M2 used in the first version of the spatial computer. We could see a late 2025 release. Apple Studio Display 2-with a possible mini‑LED backlight. This might be launched early next year. Which of the above leaked Apple products would you be interested in?
