Leaked iPhone 18 Pro motherboard hints at Apple’s next cooling upgrade

A new motherboard image claims Apple is redesigning the A20 Pro's packaging for better thermal performance.

A fresh iPhone 18 Pro leak is making the rounds online, and it comes with some pretty bold claims. According to leaker Reptalicant, the alleged motherboard for Apple’s upcoming flagship reveals a redesigned A20 Pro chip package with improved cooling, a beefier Neural Engine, and faster memory. That’s a lot to unpack, especially considering motherboard-level Apple leaks like this are exceptionally rare.

The leak claims better thermals, faster memory, and a stronger NPU

According to the post, Apple is said to be moving the DRAM to the side of the A20 Pro package using WMCM (Wafer-Level Multi-Chip Module) packaging instead of the current layout. The idea is that separating the memory from the main die could improve heat dissipation, potentially allowing the chip to sustain higher performance for longer under heavy workloads.

A20 Pro chip now adopt WMCM packaging, which move the DRAM to the side of the package, allowing for better thermal dissipation. It also get LP6 96-bit memory

The leak also claims the A20 Pro will retain a die size similar to the A19 Pro while adopting LPDDR5X 96-bit memory and a larger Neural Engine for on-device AI tasks. If accurate, it would suggest Apple is focusing less on making the chip physically bigger and more on improving efficiency, thermals, and AI performance through packaging changes.

Interesting? Yes. Convincing? Not quite yet.

The funny thing is that leaks like this almost never happen with Apple. While supply chain reports about specifications are fairly common, detailed motherboard layouts and chip packaging information rarely surface this far ahead of launch, making this rumor particularly difficult to verify.

That’s not to say it’s impossible. Apple has been steadily investing in better thermal management as its chips become more powerful, and improved packaging would be a logical next step. Better thermals would be a welcome upgrade, especially as on-device AI workloads continue to grow. But with no corroboration from Apple’s supply chain or other reliable leakers yet, this remains firmly in rumor territory.

The dream of uber cheap phones for kids and grandparents is effectively dead, thanks to AI
AI's demand for memory chips has made budget smartphones unprofitable to build.
Electronics, Mobile Phone, Phone

That $100 phone you were going to grab for your kid's first device, or hand down to grandma, could become a dream in a while. AI's hunger for memory chips just made the entire budget phone category borderline impossible to build.

So how bad are we actually talking?

Apple’s new Upgrade program launches on Tuesday with major changes
Apple's new leasing program might drop AppleCare coverage from the bundle.
iPhone 17 Pro Max

Buying your next Apple device could soon look like leasing a car. Apple is launching its new Apple Upgrade program on Tuesday, July 28, replacing new enrollments in the long-running iPhone Upgrade Program with a lease-based option that covers iPhones, iPads, Macs, and Apple Watches.

Backed by Klarna, the program is designed to lower the upfront cost of Apple's premium devices, but it is also raising questions about whether you'll actually own what you're paying for.

Setting up your dorm desk? These are the phone stands I’d actually spend my money on
From a $2 folding stand to a three-in-one Apple charging dock, these are the phone stands worth setting up this semester.
Analog Clock, Clock, Electronics

A phone stand is one of the smallest purchases on any back-to-school list, but it's also one of the easiest to get wrong, especially since there are dozens of options available on Amazon. A good phone stand is one that does its job well and, more importantly, doesn't put much of a dent in your budget.

This is one of those product categories where you don’t need to spend big, unless a MagSafe dock or a multi-device charging stand is genuinely useful for your desk or dorm setup. That is why this list begins with the most affordable options and works its way up to the more expensive ones. From a two-pack that costs about as much as a coffee to a three-in-one Apple charging station, I picked eight of Amazon's best-reviewed phone stands worth considering this back-to-school season.
