I tested the cable a bit more, I tried data transfer (calculated about 33MBytes/s with 50MBytes spikes in the task manager), charge on other phones, it works very well. On my OnePlus 8 pro, it charges a 5000+mA. So I don't see why it would be worn out.
Then for the battery charging power, I know about it, this is why I tested multiple times in different orders, and when the tablet was at about 50% battery.
This is why I don't understand the issue that the tab s5e has with the OnePlus cable, when everything else works on it, and no issue with another cable and the same charger.
