I have read that the discussions are not monitored for content but that any topic that generates a lot of discussion does influence info that gets fed back to engineering. I honestly don't know much about how all that works but that that makes sense to me. I've posted comments in discussions and have also provided info through the feedback feature. So far, the only info I have seen as a result is further comments from people like yourself posting more comments. My guess is that feedback to engineering is generated by some #AI driven system that determines which issues deserve the most attention. In other words, from where I come from... "the squeaky wheel gets the grease" :)
Sorry for the long-winded reply but this issue hits a nerve with me. But to answer your question about getting an answer to the question that is specific to the Alcatel Idol 4s, I would say, I doubt it because I don't think there are many of us asking.
I will add this though: I am convinced that the issue is software-related and not a problem with the actual batteries. The problem appears to have happened on a variety of different types of devices. My guess is that the problem gets addressed for popular devices while we the few that still use Win10 Mobile just get ignored. Sad but probably true :(
