Hey guys ,
I am not getting that good battery as everyone. I am only getting about 4-5h on screen time not like the others 7-10 hours.
What can I do to get this awesome battery life ?
Are there any tweaks,mods that I have to apply ? Is there a custom kernel that is preferable ?

Are you using a custom rom? If yes, which is it?
Have you tried disabling location settings in settings?
Have you untick location settings and remote wipe device in google play services?
Doi you have a high wakelock that's cauing the issue?

I usually get 7-10+ hours, but I also keep mine on a wireless charger if I'm sitting at my desk or if I'm away and don't need it. Here's my setup that may help your battery life:

Location Settings: Battery Saving, this especially helps on stock ROM
Kernel: ElementalX 2.6: Overclocked to 1.8 GHz and undervolted on lower frequencies with elementalx governor. Cool thermal throttling, max screen off frequency is 1.026 GHz. GPU overclock to 450 MHz, ondemand.

If your screen brightness is up over 50% it's wasting a lot of power. I keep mine around 20-25% or on Auto.

When the screen is turned off it doesn't drain too much either. Overnight, 6-7 hrs, drains maybe only 5%. I'm going on 14 hrs battery with only a little bit of charging from the wireless qi charger.

Attatched is a screenshot of battery stats.

I am on the stock rom ,
for the location services it's set to battery mode.
I don't have that high lock but after a 18-24 hour I got one or two hour of CPU total at Android System - Android OS

Thank you.
I have already put the Location Settings on Battery saving mode & I have changed the kernel as you mentioned but without overclocking the CPU the screen is always on Auto.
