iPhone 18 Pro may go full genius mode with this secret chip tech
The iPhone 18, expected next year, is said to come with TSMC's next-gen 2nm fabrication process for its SoC. This is said to be in combination with an advanced new packaging method. Reportedly, the foundry has now established a dedicated production line for Apple in anticipation of the mass production stage in 2026.Basically, multiple reports suggest that Apple's A20 chip for the iPhone 18 series will switch from InFO (Integrated Fan-Out) packaging to WMCM (Wafer-Level Multi-Chip Module) packaging. There are quite a few differences between these two packaging methods. InFO basically allows for the integration of components (including memory) within the package. The memory is typically attached to the main SoC (DRAM placed on top or near the CPU and GPU cores). This technique allows for reduced size and improved performance of individual chips, which means devices can be made thinner and run faster, all while using less power.WMCM, on the other hand, is great for integrating multiple chips in the same package. This technique allows for more complex systems which include custom accelerators as well as CPUs, GPUs, and DRAM, all fully integrated into one package, making it possible to build powerful systems that can handle demanding tasks more efficiently.
WMCM also offers greater flexibility by providing different types of chips and optimizing the communication between them, so that they can work together more smoothly and share data quickly, leading to better overall performance.

Reportedly, TSMC has now established a dedicated production line at its Chiayi P1 fab. WMCM packaging monthly capacity is expected to reach 10,000 units by 2026, according to reports. Meanwhile, expect only the iPhone 18 Pro models to be equipped with this fancy A20 2nm chip. Analyst Ming-Chi Kuo previously said that only the Pro-branded iPhones from the series will have 12GB of RAM, which comes as a result of the new packaging method. When you hear terms like "3nm" or "2nm," it's referring to different generations of chip-making technology. The smaller the number, the smaller the tiny parts (called transistors) inside the chip. Smaller transistors mean you can fit more of them on a chip, which usually makes it faster and more power-efficient. For example, last year's iPhone 16 used the A18 chip, made with a second-generation 3nm process called 'N3E.' This year's iPhone 17 is expected to have a new A19 chip, likely built on a better version of that same 3nm process, called 'N3P.' The N3P version improves performance and lets even more transistors fit on the chip, making everything run smoother and use less energy.
In my opinion, it's pretty impressive to see how Apple and TSMC keep pushing the limits of chip design. The move to 2nm and the switch to WMCM packaging isn't just a spec bump. In fact, it's a real shift in how much performance and efficiency they can squeeze out of these devices. For anyone who's into mobile tech, this kind of advancement is what makes each new iPhone generation genuinely exciting. Secure your connection now at a bargain price!

Samsung Galaxy Z Fold 7 sold me on foldables before the foldable iPhone could
The Samsung Galaxy Z Fold 7, coming out next month on the 9th, has changed that. The crease on the Galaxy Z Fold 6. | Image credit — PhoneArena So, why don't I like foldable phones? Simple: the crease. I've always said that a display should be free of any distractions, and I will never forgive Apple for popularizing the notch. Yes, yes, I know they didn't do it first, but you bet everyone rushed to copy them when the iPhone added it. foldable phone Fold 7 The thing that really sold me, however, is when I found out that the Fold 7 is only 8.9 mm when folded. Honor's Magic V5, currently the slimmest foldable in the world, is 8.8 mm when folded. Yeah, there's barely a difference of 0.1 mm here. If Samsung has improved that much over the 12.1 mm of the Galaxy Z Fold 6, then I think that it's finally time to give the company's foldable flagships a try. Because now it really feels like Samsung has pulled all the stops and made a phone worth considering. A leaked render of the Fold 7, showing off its slim side profile. | Image credit — Evan Blass I'd completely abandoned hope of Samsung making a worthy foldable smartphone. All bets were now on Apple, who, despite their many recent goofs, might just deliver a crease-free foldable iPhone . Fold 7 foldable iPhone

Oppo Reno15 details leak with major shake-ups
Before you hit up the comment section to inform us, YES, we are well-aware that the Reno14 and Reno14 Pro were only launched in China last month and have just begun their international rollout, with upcoming launches in Malaysia on July 1 and India on July 3. This is all to say that the Reno15 family is still a ways off from announcement. That said, it appears to be far enough in development for some details to start leaking. Industry insider Digital Chat Station has suggested that the Reno15 and Reno15 Pro are already being tested with 200MP main cameras on board. That's up from the 50MP shooters on the Reno14 line. Quite the potential upgrade. Both phones are also tipped to have a periscope telephoto, which is not surprising given that both Reno14 models have one. Reno15 info In a potentially more interesting possible development, the source also hints at a substantial downsizing for both phones. Allegedly, the regular Reno15 will feature a 6.3-inch display, effectively making it a 'compact' device by modern standards. Definitely smaller than the 6.59 inches of the Reno14. The Reno15 Pro will also apparently be downsized to 6.78 inches, compared to the 6.83 inches of the Reno14 Pro. Last but not least, Digital Chat Station claims that Oppo is considering new flagship hardware for the pair. We aren't sure exactly what that entails, but he does mention wireless charging and metal middle frames, so there's that. Source (In Chinese) | Via

Apple Watch SE 2 drops to an even more affordable price with this deal
The Apple Watch SE (2nd Gen) may not technically be an uber-premium smartwatch, like the Apple Watch Ultra 2, for example, but it's the Apple Watch to get if you're on a budget or just don't want to overspend. With a starting price of about $250, it's way more affordable than Apple's high-end smartwatches. On top of that, you can often find it selling for even less on Amazon. In fact, it's even cheaper right now, as the e-commerce giant has slashed $60 off its usual price, letting you grab the 40mm GPS version for just under $190. The best part? Almost all color options are discounted by that much, letting you score sweet savings regardless of which one you go for. $60 off (24%) Act quickly and save $60 on the 40mm GPS Apple Watch SE (2nd Gen) on Amazon. Packed with features, it gives you the full watchOS experience at a bargain price. Don't miss out! Buy at Amazon Sure, the discount was $80 a few weeks ago; however, we think the current markdown is still pretty solid. After all, this smartwatch packs almost all the features of the Apple Watch Series 10, but at a lower price. So, any chance to save even more on it should be welcomed. Since it runs on watchOS, you can enjoy the full Apple Watch experience, including downloading a plethora of apps from the App Store. Meanwhile, it supports safety features like Emergency SOS, Fall Detection, and Crash Detection, so you can count on it in case of an emergency. It's also loaded with health-tracking features, missing only things like ECG, blood oxygen tracking, and temperature sensing. And while it lacks an always-on display, it still delivers all-day battery life—just like the pricier Series 10. So, yeah!
