There is little doubt at this point about the great capabilities of the Apple Watch to be our companion in battle and show us not only notifications, but also in the area 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 of Apple Watches would be negligent.
The good news is that this could soon improve significantly thanks to TDK, a veteran Japanese company that has recently specialized in batteries and is one of Apple’s main suppliers. They discovered a new improvement for batteries which amounts to giving less for more. And this applied to small devices like the Apple Watch can be a revolution.
Capacity up to 100 times greater than current batteries
“We believe our new solid-state battery material 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 constructed with a ceramic material with a solid electrolyte consisting of lithium oxide and alloy anodes. This allows the new energy density of the batteries to reach around 1,000 watts/hour per liter. And to put current batteries in context, let’s say that this data multiplies current capacities by 100.
Transform this data into useful information for the consumer, claiming that it will essentially enable have larger battery capacities in smaller sizes. So, without even needing to increase its size and therefore having to extend that of the Apple Watch, we could have greater capacities that considerably improve autonomy. Not up to 100 times more, since its capacity is not directly proportional to the autonomy it provides, but a substantial improvement is expected.
When might we see Apple Watch with these batteries
Here there is regular news and good news. The normal thing is that it won’t be something immediate and the good thing is that we won’t have to wait too long. Additionally, 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 to experiment during these months and that they will be delivered to their customers next year.

Apple being one of these customers, and as long as they see that this is indeed a tangible advancement, they could give their approval next year and perhaps arrive in time to integrate it into the Next year’s Apple Watch. We wouldn’t bet blindly on this either, as the testing process is a bit longer and perhaps very tight on schedule, but the fact is that 2025-2026 shouldn’t happen.
Now though, We don’t expect to see these batteries on iPhone, iPad or MacBook. The reason is none other than the difficulty posed by these types of batteries 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. .
