The battle for the world's thinnest smartphone is heating up, and the newly released Motorola Edge 70 has just thrown down a significant gauntlet. But how did Motorola achieve its sleek profile without the usual compromises? A fascinating new teardown video has ripped the phone apart to reveal its engineering secrets, uncovering a display that redefines "ultra-thin" and a battery capacity that leaves its direct competitors in the dust.
The detailed dissection, performed by the popular tech channel Kingmi Mobile, offers an unprecedented look inside the Motorola Edge 70. While the device feels remarkably svelte in the hand, the internal layout tells a story of strategic innovation and clever space-saving.
The Crown Jewel: A Revolutionary 1mm Display
The most jaw-dropping revelation from the teardown is the phone's screen. Kingmi Mobile's precise measurements confirm the Motorola Edge 70 sports an astonishingly thin 1-millimeter display panel.
To put that in perspective, this makes the screen a full 50% thinner, or half as thick, as the 2-millimeter panel used in Apple's acclaimed iPhone Air. This breakthrough in display technology is a key enabler for the Edge 70's overall slim design.
But a thin screen often raises concerns about durability and performance. Motorola seems to have preempted these worries. Despite its minimal thickness, the display doesn't cut corners on specs. It boasts a buttery-smooth 120 Hz refresh rate for seamless scrolling and gaming, and can punch out an eye-searing 4,500 nits of peak brightness, ensuring perfect visibility even under direct sunlight. For protection, it relies on the trusted strength of Corning Gorilla Glass 7i, suggesting that "thin" does not have to mean "delicate."
The Power Paradox: A Massive Battery in a Slim Frame
Perhaps even more impressive than the thin screen is how Motorola used the saved space. The teardown video clearly shows that a massive, sheet-like battery dominates the internal real estate of the Edge 70. By leveraging the slimmer components, engineers were able to fit a colossal 4,800 mAh power cell inside the chassis.
The numbers are stark when compared to the competition. This battery capacity is over 50% larger than the one found in the iPhone Air and represents a 23% increase over the battery in Samsung's Galaxy S25 Edge. This addresses a primary concern for users of slim phones: battery life. The Edge 70 isn't just thin; it's built to last, potentially offering users a full day—or more—of use on a single charge. Interestingly, despite its large surface area, the battery itself is only 3.9 millimeters thick, a testament to advanced battery cell technology.
So, how does this all fit together? If the components are so thin, why is the final product slightly thicker than rivals? The complete Motorola Edge 70 measures 0.4 mm thicker than the iPhone Air and 0.2 mm thicker than the Galaxy S25 Edge. This minimal extra girth is likely attributed to a more robust internal structure and additional features that the teardown also uncovered.
Beyond the Basics: Cooling and Connectivity
Kingmi Mobile's analysis didn't stop at the screen and battery. The YouTuber highlighted a compact but highly efficient cooling system designed to manage heat from the processor, ensuring sustained performance during intensive tasks without resorting to a thicker vapor chamber.
Furthermore, the teardown noted an "abundance of antennas" woven throughout the device's frame. This strategic placement suggests that the Motorola Edge 70 could offer significantly stronger signal reception for both cellular and Wi-Fi connections, a critical but often overlooked aspect of the user experience.
For those intrigued by this blend of ultra-thin design and exceptional battery life, the Motorola Edge 70 is now available.

The Motorola Edge 70 teardown ultimately paints a picture of a device that prioritizes intelligent engineering over mere thinness for its own sake. By pioneering a dramatically thinner screen, Motorola has created the space for a battery that outclasses its peers, all while packing in top-tier display specs, capable cooling, and enhanced connectivity. It’s not just a new phone; it’s a masterclass in modern smartphone design.
