iPhone 17 Pro is said to use a new thermal system

Apple could finally be bringing a major cooling upgrade to its iPhones. If the new leak is accurate, the iPhone 17 Pro and iPhone 17 Pro Max may feature a vapour chamber cooling system. This is something which Android phones have used for years, but iPhones have so far avoided. A tipster who goes by the name Majin Bu has shared an image of what is believed to be a new copper heat plate. This is reportedly a part of Apple's vapour chamber system, which is still in the testing phase. The design is said to be evolving, and there are still some technical issues that need to be sorted out before it's finalised.advertisementFor context, most high-end Android smartphones like the Samsung Galaxy S25 Ultra already use vapour chamber cooling. This system uses liquid inside a sealed chamber that turns to vapour when the phone heats up. The vapour then spreads the heat across the plate, cools down, and becomes liquid again, allowing the process to repeat. This setup helps the phone stay cooler during heavy usage, such as gaming or long video recordings.Currently, iPhones rely on basic cooling methods that involve spreading heat through the metal and glass parts of the body. But this approach isn't always enough. iPhones can get warm and sometimes even show temperature warnings, stopping certain features until the device cools down. If the new vapour chamber system does arrive, it could prevent these situations by offering more stable performance during intense tasks.advertisement
The possible reason behind this change could be Apple's growing focus on AI features. With upcoming iPhones expected to support new AI-based tools, branded as Apple Intelligence, the processor inside will likely have to handle more demanding tasks. To support that, better thermal management would be necessary. The iPhone 17 Pro is expected to run on the new A19 Pro chip, which could also generate more heat under pressure.Past reports have already hinted that Apple was planning to move to this type of cooling setup. Popular analyst Ming-Chi Kuo had earlier predicted that only the Pro models would get vapour chamber cooling, not the regular iPhone 17. It's worth noting that Majin Bu, the source of the latest leak, has had a mixed record. While he has correctly shared some Apple updates in the past, he has also made a few inaccurate claims. So, while the image of the copper plate has caught attention, it should still be treated as an early leak and not confirmed information.Apple is expected to unveil the iPhone 17 lineup in September 2025. Until then, we will likely see more leaks and reports that could give us a better idea of what's coming. But if this new thermal system does make it to the final product, it could be a welcome improvement for users who often push their iPhones to the limit.

iOS 26 Brings AI-Powered Battery Saver — But Only to Select iPhones

Apple's latest software update, iOS 26, brings several under-the-hood enhancements — and leading the pack is a new AI-powered battery-saving feature known as Adaptive Power. While the update is available for older models, this exclusive feature is restricted to iPhones equipped with Apple Intelligence, a capability found only in higher-end models. According to a MacRumors report, the Adaptive Power feature will be available only on the iPhone 15 Pro, 15 Pro Max, and the entire iPhone 16 lineup, including the iPhone 16, 16 Pro, 16 Pro Max, and 16e. Apple describes Adaptive Power as a tool that 'makes small performance adjustments to extend your battery life, including slightly lowering the display brightness or allowing some activities to take a little longer. Low Power Mode may turn on at 20 per cent.' The aim is to subtly tweak background processes and system behavior when battery consumption is higher than usual, thereby enhancing overall endurance without a major compromise in user experience. Despite iPhones as old as the iPhone 11 being eligible for the iOS 26 upgrade, the Adaptive Power feature is not supported on devices lacking Apple Intelligence. That includes the standard iPhone 15, which, although part of the same series as the 15 Pro, misses out on this AI integration. The feature is expected to be especially beneficial for Apple's upcoming iPhone 17 Air, rumoured to be the slimmest iPhone ever at just 5.5mm thick. With speculation around it housing a 2,800mAh battery, Adaptive Power might become essential in helping the phone maintain a solid battery life while preserving performance. Apple is likely to unveil the iPhone 17 lineup — including the 17, 17 Pro, 17 Pro Max, and the much-anticipated 17 Air — in September, alongside the stable release of iOS 26, which is currently available as a developer beta. As users await the next generation of iPhones, Adaptive Power stands out as a thoughtful addition, aimed at addressing the long-standing challenge of balancing slim design with long battery life.

Personalisation and flexibility Users can browse through the AI-generated wallpapers and select one immediately, or refine the design further by editing the prompt. This gives them control over: Colour palette Visual theme Artistic style The feature aims to offer a more immersive chat experience, especially for users looking to go beyond WhatsApp's standard static wallpaper options. Useful for themed conversations According to the report, dynamic wallpapers could be especially useful for group chats, such as those created for event planning, travel, or occasions. By using prompts aligned with the chat's purpose, users can tailor the visual tone to reflect the context—adding a creative layer to conversations. This feature marks another step in WhatsApp's broader strategy to integrate personalisation and AI tools, enriching the everyday messaging experience.
