I have a new longer charging cable to charge my phone (5C). The past few days. I have had great difficulty charging my phone with my cube. (I still think there is something wrong with it.) So, today, while I am sitting here typing this, I have phone charging and it won't charge past 82%. Though, as I am typing this. I think I realized my problem. I do have the battery health app on my phone and it does take note of what my battery capacity is. I always thought that no matter what the battery capacity was, it would read that 100% of the 80% of my battery was charged. Do I have the right idea? I do plan on upgrading my phone soon if the rumored release date of a certain iPhone is right. I just have a few more weeks. I also get a USB devices is disabled pop-up. What's going on?
