We'll need more info to better assist you

charge the phone 100% use it as you normally would then once the battery reaches 10%

settings > power management > battery > take screenshots of:

1. the list

2. tap on the graph and take a screenshot

3. back > tap on the top 4 items on the list > take a screenshot of each 

Then charge the phone 100% > boot in >>> safe mode take the same screenshots once the battery drains to 10% 

post them all here or upload the screenshots to box or dropbox or google drive or etc and post the link

In Marshmallow battery life is better than on lollipop. So it's a good idea to update your phone.

Seems that poor battery life is because of non stop working GPS - it use more current and this is normal. On both screenshots for safe mode and normal GPS work most of time. So turn off GPS and try again, I'm sure that battery life will increase dramatically.

The WiFi it's on all the time, that's draining your battery quite fast. Also, I think the list it's not full, there are missing percentages but it's the WiFi.
