As an American I look at the spying issue like this. There's not really a choice to get a piece of network connected technology that's not spying on you. The choice you have as a consumer is who will most likely be the one spying. China has less interest in and less ability to mess with my daily life than the American government or American oligarchs. China doesn't care if I want to download a movie or if I, individually, engage in some form of protest. On top of that it's generally cheaper for me to buy the spying device that enables China to spy on me than the device that allows America to spy on me. So ultimately I say, "China, here's my data. Don't tell my own government or the corporations that control it."

Btw there's a carveout in the EU battery regulation basically exempting a lot of phones.

As long as they have batteries that are rated for enough charging cycles they don't have to comply.

I'm not so sure China spies at hardware level, or if they do, they must be using the same tricks as US designed devices. Otherwise the US agencies would have taken a certain pleasure outing the backdoors to discredit chinese phone makers.

So either they (NSA, others?) didn't find anything, or revealing the finding would help reveal the US planted backdoors.
