The person writing these lines has an American mobile phone—made in China—with a little more 5,000mAh. A figure in which giants like Apple, Samsung or Google have been comfortably installed for years.
Meanwhile, in China, Honor has just made official a phone with a 10,000 mAh battery. The launch is not surprising just because it has managed to literally introduce a powerbank inside a smartphone. It is surprising because it breaks a barrier that until now no one had dared to cross. Not due to lack of possibilities, but due to industrial inertia.
The aforementioned. Honor has made the Honor Win and Honor Win RT. Two phones that, in addition to having the best Qualcomm processorshave a 10,000mAh battery made of silicon-carbon technology. The message is clear: this is not a typical high-end, it is proof that China is the leading benchmark in batteries for smartphones.
thickness. For years there has been an unwritten but unquestionable rule: more battery means more thickness. The 10,000 mAh were reserved for rugged, bulky mobile phones designed for very specific uses. These Honor Win break that logic. They are thinner than a iPhone 17 Pro Maxbut with double the energy capacity. There are no gimmicks, fine print or marketing exercises: it’s a real leap in energy density.
How did they achieve it?. Honor has not specified how they have managed to take the capacity to such an extreme but the person responsible is clear: silicon-carbon. This technology has been demonstrating for years that it is possible to introduce much denser batteries in the sizes in which lithium has already reached its ceiling.
Chinese mobile phones have been standardizing for more than a year batteries over 7,000mAhand Honor’s move to reach five figures marks what aspires to be a new standard.
The cons. Silicon-carbon poses certain challenges, and the first is degradation. These batteries, especially in their first generations, They seemed not to be at the same level as classic lithium batteries. Over time, the promised charge cycles are virtually identical to those of traditional lithium batteries (more than 1,500).
The second is the cost: producing this type of cells is more expensivewhich partially explains why, for the moment, these figures reach China first and not global markets. In fact, a common practice is to find models whose Chinese version has more battery than the global version, reserved for the rest of the markets.
A third key point is related to security and regulation. Denser batteries require stricter controls, and Western regulatory frameworks are not always prepared to adopt these types of advances so quickly.
None of this invalidates progress. It simply explains why Apple, Samsung or Google have not yet made the leap. It’s not that they can’t: it’s that they haven’t wanted to take the risk… yet.
China is going to force a move. The 10,000mAh batteries are, without much room for doubt, one of the biggest technological leaps in the world of smartphones after the arrival of AI. A figure that will allow us to normalize the three days of average use without going through the charger.
The leap is so relevant that, whether they like it or not, “traditional” manufacturers will have to start making a move, as they had to start doing with fast charging systems. Samsung has already started implementing the 7,000mAh in phones like the Galaxy M51but its high-end is still at the 5,000mAh barrier. Google also moves in the 5,200mAh and Apple… is Apple.
With a greater or lesser pace of implementation, these manufacturers are forced to keep pace with China in these advances. And that translates into admitting that we were wrong about lithium.
