Problem live-view vs viewfinder in Canon 77 D

[ssantra]

I am  using  Canon 77D with canon 50 mm lens. I am noticing something strange. When I am taking photos with the help live view, I am getting very nice photos but when I switch back to viewfinder, my clicked photos is not as good as the one I have taken with the help of live view. Can anyone suggest me a solution to this as if I use live -view the camera battery drains out  in an hours time.

Can you post an example of an image taken when using live view and one (hopefully of the same subject) taken when using the viewfinder?

Are you in manual or auto focus?   A complete guess here, but if you're in manual focus and your viewfinder's diopter is not set correctly, that could lead to issues.

Hi and welcome to the forum:
When you are viewing these images are you seeing them in the viewfinder or the LCD?   When you look at the numbers displayed for settings in the viewfinder display, are they sharp or fuzzy?
