My Samsung Galaxy S4 gets very hot when charging.

My problem is that my Samsung Galaxy S4 gets very hot when It is in my pocket or laying idly on a table and the battery capacity falls very rapidly. Often I have to charge the phone two or three times a day.

Any idea?

That sounds as if the battery is at the end of its life. If you use it like the OP back in 2013, letting it drop to 10% regularly, you'll get less than a year out of it. Replace it (S4 batteries aren't expensive) then try to never let it get below 40%. If you need more than that buy 2 batteries and a charger and switch batteries mid-day. Then charge the one in the phone and the one out of the phone at the same time at the end of the day.
 
hey guys
