Moto Edge 70 Enters the Ultra-Slim Ring to Fight the Galaxy S25 Edge and iPhone Air

Motorola seems ready to present a remarkable battery jump in its upcoming thin smartphone; recent leaks point to a daring move that would defy industry standards. While rivals rush to trade off power for slimness, the Edge 70 seems poised to defy that tradeoff.

The forthcoming Motorola Edge 70 will have a 4,800 mAh battery, which distinguishes it among ultra-slim devices, according to a teaser released on Motorola’s official Polish website. Under-the-hood chemistry makes this claim more interesting: the corporation calls the battery a silicon-carbon unit, promising more effective energy transfer. Early tests show that this technology could allow the Edge 70 to punch well above its weight in day-to-day endurance as to traditional lithium-ion designs.

To give this perspective: Motorola is aiming for a device thickness close to that of Samsung’s thinnest models, about 5.8 mm, while packing much more battery capacity. For instance, Samsung Galaxy S25 Edge is expected to have 3,900 mAh in the same footprint, ultra-thin iPhone Air model is reported to come with something closer to 3,100 mAh. 

Beyond the battery, the teaser page reveals more small insights. The Edge 70 should be IP68 and IP69 certified, indicating dust and water resistance at demanding levels. It was also cited as a 50 MP camera and Gorilla Glass 7i, potentially utilized for the display cover. Regarding price, Motorola seems to be aiming in the €799 to €899 range, implying that the company sees this as a premium offering. 

On the performance front, leaks point to a Snapdragon 7 Gen 4 processor paired with 12 GB of RAM. Charging features are expected to include 68 W wired and 15 W wireless charging, maybe using Qi2 standards. Should all of these factors line up, the Edge 70 could come not only as a slim gadget but also as a major rival at the flagship level. Motorola’s plan with the Edge 70 finally seems straightforward: question the assumption that thin phones have to give up battery life.
