Honor used MWC 2026 to showcase what the future of smartphone batteries would look like with its all-new Silicon-Carbon Blade Battery. The “blade” concept refers to the battery’s extremely thin form factor, which is designed to fit into compact devices while delivering higher capacity.
The new battery design significantly increases silicon content to 32 percent and achieves an energy density exceeding 900Wh/L, pointing to much larger battery capacities without increasing device thickness.
According to Honor, this advancement could enable future foldable smartphones to feature batteries of 7,000 mAh or more, addressing long-standing limitations around battery size in slim and foldable designs.
Honor showed off the thinness of this new blade battery in the hands of Rick Smith Jr., who holds several Guinness World Records for card throwing. The video shows the record holder throwing the new blade battery to slice a plant, and then into a folding phone. We will let you judge the video yourself.
Building on this technology, Honor confirmed that the Magic V6 already benefits from its fifth-generation Silicon-Carbon battery developed in partnership with battery manufacturer ATL. The battery uses 25 percent silicon content, which Honor described as the highest level currently used in the industry for commercial smartphones.
This high silicon concentration allows the battery to achieve greater energy density, making it possible to fit more power into a smaller physical space.
The Honor Magic V6 is among the first major device announcements at MWC 2026 and has drawn attention for combining an ultra-slim design with a large battery. The foldable measures just 4.0mm when unfolded and 8.8mm when folded, while still housing a 6,660 mAh battery.
