I think you are trolling, but, in case I'm wrong, I explain the concept in other words: modern phones need a charger able to provide current to the phone battery in order of Amperes (A) the one is on my desk now is 5A and can charge the phone, let say, in 1h, to simplify, let say that we need less 1A for 1h. 1 microAmpere is 1A divided by 1'000'000 so, to fully recharge my phone with a microampere, I need 1'000'000h or 114 years, with 100 mA, only 1,14 years, 10% 1 month. And these are optimistic values. So what should be the use case of that bullshit ? Emergency ? I don't think so, better a solar panel. To prolong the daily life of the battery of 1 millisecond ? But reducing drastically the space for the real battery so you have a phone even with less autonomy. Is it laughable ? Again, applying the science and not magic or sci-fi you simply can not do a nuclear powered cellphone for day-by-day use, at least one with the same volume and weight of a modern smartphone. Maybe something 1m^3 x 200kg. Problem here is that Ark reactor and Unobtanium you see in movies are not possible and there is a magical undiscovered and ultralight material to shield high level of radiation. This kind of nuclear batteries are useful for niche application, to save the state of small memory amounts, etc and are not suitable to power cellphones or drones, this will never happen. What happen is there are lot of people confusing Marvel movies with reality and want to give real money to companies that simple produce scam. This could not be the case because I did not translate the Chinese webpage of the company, I suspect here the problem is the english article, but, if the translation is correct , no doubts , if they declare they can power the phone with nuclear batteries is a scam.
