Welcome back, butlerlt!
May I ask when you first purchased or received your Samsung On5? If it's been a while, it's not out of the ordinary for specific parts to degrade or lower performance. In other cases, it may just be as simple as turning off Bluetooth when you're not using it and Switching on Wifi when it is available.
Have you already looked at How can I Monitor and Extend Battery Life for My Samsung Galaxy On5? (SM-S550 and SM-G550)?
Please let me know!
