In contrast, major US smartphone brands such as Apple, Google, and Samsung continue to rely on traditional Lithium-ion batteries, overlooking the advantages offered by compact and high-capacity silicon-carbon alternatives. Previously, consumers interested in silicon-carbon batteries had limited options, primarily with OnePlus devices. With this latest development, Motorola is set to offer the first flip phone equipped with a silicon-carbon battery in the US market.
The Razr Ultra 2026 is scheduled for release on May 21, 2026, with pre-orders starting a week earlier. It maintains the same dimensions as its predecessor, measuring 88.1mm tall, 74mm wide, and 15.7mm thick, while weighing in at 199 grams. Motorola highlighted that the new battery chemistry grants users longer battery life without compromising the phone's sleek design.
The Razr Fold also utilizes a silicon-carbon battery, featuring a capacity of 6,000mAh within a foldable design measuring only 9.89mm thick. Its weight is 243 grams, which accounts for more than just the battery. The device supports various charging methods, including 80W wired charging, 50W wireless charging, and 5W reverse wireless charging, showcasing the latest advancements in battery technology for foldable smartphones.
Both models are expected to be broadly available through retailers, with the Razr Fold also being offered by T-Mobile, Xfinity Mobile, and Verizon in the coming months. This accessibility is essential, as most smartphone consumers in the US typically purchase their devices through carrier agreements.
