The latest A-series processors from Apple create more heat, and controlling this heat is now a major problem. In 2023, many iPhone 15 Pro users complained about overheating problems, which made them unhappy. Even though the iPhone 16 hasn’t received many complaints yet, Apple is determined to fix this problem for the iPhone 17 models that will arrive soon.
Apple’s Chinese tech site MyDrivers says the company will use vapor chamber cooling in all iPhone 17 models. This new cooling method can handle heat better than the normal heat sinks used in current phones. The cooling system uses a sealed liquid container that turns into vapor when heated, sending heat through the chamber to colder sections. The liquid moves through the chamber, cooling down as it changes from gas to liquid, and does this process again, cooling the device without taking up much space. The new cooling system could be especially important for the iPhone 17 Air, which is expected to be one of the thinnest iPhones yet at 5.5mm.

Even though Android phones like the Samsung Galaxy S10 Plus already used this technology last year, it’s still an important improvement for Apple. Apple needs this upgrade because it plans to put its A19 Pro processor on a 2nm process, which will make it faster but also likely create more heat.
Some think Apple will introduce the vapor chamber cooling system only on the iPhone 17 Pro Max, following a pattern where it offers special features first to its top-tier phones. But if early tests show too much heat, Apple might decide to use this cooling system across all its new iPhone models.
When Apple shows off the iPhone 17 in September 2025, vapor chamber cooling will likely become standard, making their phones run cooler and work better. Everyone interested in tech and Apple products will be closely following this development.
