I just purchased a iPhone 8 and I was trying to charge it using my Qi charging base that I used on my former Nexus 6. The base worked fine on the Nexus 6 but on the iPhone, it squeals (not sure whether it is the iPhone or the base, but it sounds more like the base) and stops charging regularly. The charge level does go up during this process, but it is so irritating that I have to stop as I also fear damage to the iPhone. I used both the Nexus 6 and the iPhone USB power adapter and the result is the same. For me it seems that the iPhone pulls more power than the Qi base can support. It there a way to reduce the power drawn by the iPhone via wireless charging?

The Qi charger is a Itian model A2.
