Samsung buried a charging diagnostic tool in an app you probably uninstalled
I stopped guessing about my Samsung's charging problems after finding this hidden diagnostic.
Charging a phone should be boring. You plug it in, it charges, you move on. When that stops working reliably on a Samsung, the usual instinct is to swap cables, restart the phone, and wait to see if it fixes itself. That works sometimes, but it misses real causes that add up over time. Luckily, Samsung actually built some diagnostic features right into an app on your phone.
