What's wrong with my phone? My dad bought me a Samsung Galaxy s5 Neo in 2016, and I've had no issues with it until now. In the past two weeks, I've noticed that my phone charges extremely slow (to the point that I charge it for an entire day and it still isn't at 100%) or the battery decreases whilst charging. I've changed the battery and the power cable, charged it on safe mode, deleted storage space and apps, and yet, nothing seems to work. What's wrong with my phone?
