I have a samsung galaxy 4 . a lot of time i will put on data on my phone and it continually shuts down . it will 60% charging left bon it and after it shuts down its on 2%. has anyone else experienced this? does anyone know what is the problem?
The S4 is an older device and the batteries certainly don't last forever.
The good news is that you can pick up a new battery relatively cheaply on eBay or Amazon.
Make sure also to check under settings...battery to see what apps might be eating your battery. Facebook has been known to be a battery hog. There are alternatives like Metal if that's happening to you.
