hard to understand if you have a question, a concern, or a legitimate issue, so I'll do my best ...
14 hours with that much use is 'normal'. the apps for facebook, messenger, snapchat, and what's app, typically don't have a lot of battery usage unless they're open on the screen and being used. having said that, it means the screen is on and the phone is active. this will drain the battery life significantly more than just letting the phone sit idle. in addition, anything you do that uses more power, such as camera in snapchat, will add to the battery drain.
I've had days were I'm able to easily go from 8a-1a without needing a bump  charge. other days I'm having to charge again about dinner time (630-730).
bought it 2nd hand so really haven't experience a good day with the batterythanks for reply it's just I need phone with battery all day so can browser listen music and all thinking of buying moto g5 plus.. but think that be massive downgrade.  Heard  good reports tho.  That's 14 hours in power saving mode if I use it full boot on days off get bout 4r5 hours..
