Why do Apple and Samsung still say no to 10,000mAh batteries?

Although silicon-carbon batteries offer extremely large capacity, big companies like Apple and Samsung are still cautious, the reason lies in technical risks and long-term durability.

Some Chinese smartphones like Honor X70 or OPPO K13 are causing a fever with 7,000 to 8,300mAh batteries using silicon-carbon technology.

This technology replaces graphite anodes with silicon, increasing energy density without increasing battery size.

However, this type of battery is prone to expansion when fully charged, which can increase in volume by up to 300% and cause physical pressure on the components.

To minimize the risk, manufacturers must use silicon-carbon composite materials, a solution that stabilizes the battery but reduces its lifespan.

Additionally, many carriers have to split the battery into two cells to overcome the 20Wh per cell energy limit barrier for air transport.

Apple, Samsung and Google still prioritize safety, stable performance and long-term durability for devices.

They do not chase after "huge" battery capacity but ignore the problem of temperature, expansion and actual life.

While silicon-carbon technology is promising, it will take time before it is safe enough for mainstream high-end smartphones.
