Thanks for your patience. I have looked into your request and unfortunately I cannot provide you with that level of detail in regards to any of our components.
Our batteries are rated and have a guarantee that they will last for at least a certain amount of cycles, the number of this can differ regarding the device and these details can be found on our website under the technical specifications for the different devices.
Please let me know if you are experiencing any specific issues with your device and I will be happy to look into it for you.
So they are not digging into it, and not relaying to their providers. Which is not unexpected. But they’re available if we have a specific issue.
I would also assume that most manufacturers are going to adapt their processes quite quickly. Plastic is not a high-tech component, and swapping it for a higher-quality one is probably not that much more expensive either compared to the costs of lithium, cobalt etc..
