There is little doubt at this point about the great capabilities of the Apple Watch to be our battle companion and not only showing us notifications, but also in the field of health and sports. However, as many sensors as they have, and in constant operation, cause one of the worst evils of the Apple Watch: the battery. Despite recent improvements and the good work of models like the Apple Watch Ultra 2, denying that autonomy is the weak point in Apple watches would be negligent.
The good news is that it could soon improve substantially thanks to TDK, a veteran Japanese company that in recent times specializes in batteries and is one of Apple’s main suppliers. They have discovered a new improvement for batteries that boils down to giving less for more. And that applied to small devices like the Apple Watch can be a revolution.
Up to 100 times greater capacity than current batteries
“We believe that our newly developed material for solid-state batteries can make a significant contribution to the energy transition,” said Noboru Saito, CEO of TDK. A statement that helps us explain the innovation that the Japanese company has been pursuing for some time.
These are new solid-state batteries built with a ceramic material with a solid electrolyte made from oxide and lithium alloy anodes. This allows the new energy density of the batteries to become around 1,000 watts/hour per liter. And to put the current batteries as context, say that this data multiplies current capacities by 100.
Transforming this data into useful information for the consumer, saying that in essence it will allow have larger battery capacities in smaller sizes. Therefore, without even needing to increase its size and consequently having to expand that of the Apple Watch, we could have greater capacities that considerably improve autonomy. Not as much as 100 times more, since its capacity is not directly proportional to the autonomy it provides, but a substantial improvement is expected.
When could we see Apple Watch with these batteries
Here there is some regular news and some good news. The regular thing is that it is not going to be something immediate and the good thing is that we will not have to wait too long. What’s more, TDK itself confirms that in 2025 they want to send the first samples. The exact status of this development is unknown, but it is foreseeable that they will continue experimenting in these months and that they will be delivered to their clients next year.

Apple being one of those clients, and as long as they find that this is indeed a tangible advance, they could give their approval next year and perhaps arrive in time to incorporate it into the Next year’s Apple Watch. We would not bet blindly on it either, since the testing process is somewhat longer and perhaps they are very tight on time, but the fact is that the 2025-2026 period should not happen.
However, It is not expected to see these batteries in iPhone, iPad or MacBook. The reason is none other than the difficulty that these types of batteries entail due to the fragility of their materials. In small devices like the Apple Watch, there does not seem to be a big problem, but there is when we talk about larger devices, since the fragility of the batteries multiplies and could cause breakages and ultimately the remedy would be worse than the disease. .
