lumia 1520 battery life before & after hard reset

Good day folks,

I am Lumia 1520 user for a year.
The problem happened lately is regarding the phone battery.

Before this i can easily hit a day with heavy usage after fully charged.
Lately, i just can hit around 8-10 hours only.

So i did a hard reset on the phone. On the first 100% charged after hard reset, the estimated time is max to 1d15h. When I used the phone until the estimated time is below 15hours, fully charged again won't get 1d15h. Max is 15hours only.

Is my battery got problem or the software?
Anyone has idea about this?

Go to battery saver...and change setting...that is change which app you want to run in the background...and after that make a soft reset...and see does it makes a difference in the time

Thank you bro for the tips.
I did the same thing as per your instruction.
Still in experiment. I fully charged the battery, then drain it below 15hours estimated time.
Still checking its performance.
