Samsung 4 battery draining

Solution
You don't know without checking things out. If the draining stops while in "Safe Mode" then you need to look at when the problem started. Was it after you downloaded a specific app? or after an app update? Was it after you downloaded another kind of file? Those are good places to start. You should also try scanning the device for malware and viruses.
