A number of Chinese brands use LFP batteries due to the local flight ban on lithium ion batteries.


You are conflating power banks and smartphones.

In China, the current trend in "high-end" smartphones/laptop is to switch to higher-energy silicon-anode batteries. LFP is primarily for low-energy dense (gravimetric/volumetric) storage devices, such as power banks; or in vehicles, low-end/low-range EVs, or stationary energy storage (ESS) -- BYD being one notable exception.

China implemented rules in mid-2025 banning uncertified (no 3C mark) and recalled power banks from Anker & Romoss models, from domestic flights due to fire risks.
