Has anyone paid attention to this: How durable is the S10 with aluminum alloy backplate

I have tossed with my watch several times this year, and I still feel more comfortable using it. Currently using awu, the battery life is better than the s series, but the volume is really too large, thick and heavy, especially wearing long-sleeved clothes is very troublesome. This generation of s10 is considering upgrading when it is released, but there are a lot of slots (doubts): 1. Licensed castration fast charging 2. The new sleep apnea is not 3. Aluminum metal backsheet replaces ceramic I also saw the third point before. After searching, I found that aluminum alloy is not as sweat-resistant as ceramic. The back of the S10 may feel spendy after being used for a long time. In addition, with the charging debuff, I am considering whether it is better to switch back to the S9. At present, the 46mm S10 Air China supplement is about 2,800, and the stainless steel exterior version of S9 is about the same price. I kind of want to buy a stainless steel S9 directly.
