Default [Q] Normal Battery Life with Stock Battery?

I'm on CM11 M6 and I recently was forced to switch back to the stock OEM 2100 mAh battery from Samsung due to a heat problem with my external battery. I'm just trying to see if what I'm getting is normal battery life or if there is any tweaking I can do to improve battery life?

ROM: CM11 M6
Kernel: KT747 AT&T 4.4 with Asswax CPU governor and BFQ scheduler
Battery: Stock OEM 2100 mAh

You seem to be around normal results from what I've gathered. On stock battery you should be getting around 4hrs of screen on-time. This of course varies on the age of the battery as they run out of juice as they get older.

4.3 touchwiz only gets me 2:45 on screen time, 4 hours is generous.

I've only ever been able to get 4+ hours of screen-on time with a larger 4200 mAh battery from Hyperion. At the most on either AOSP rom's or stock rom I get about 2.5, MAYBE 3 hours depending on kernel setup.

Yeah thats way below norm imo. I can't prove it atm as I haven't used my phone as much today but I've attached a SS of my stats as they stand atm.

I've got approx 2hrs of listening to music on there. Thus the large difference between screen on/awake time. Otherwise after 10+ hrs of discharging it's looking great to me.

I'm thinking of leaving my screen on for a couple hours tomorrow, I'll come back with the results if I do perform the test.

Here you go gents, after 2hrs of screen on time I still have 50% of my battery remaining. Leaving me with approx another 2+hrs in the remaining battery life as the initial 2hrs was gathered in almost 5hrs. This is using the stock Samsung 2100 mAh battery.

How are you achieving these stats? One of the things about Android that really pisses me off is I always feel the need to do my own power management and I can't seem to find a way that sticks.

I don't do much to be completely honest. The only thing I do specific to power management is use Greenify to Hibernate apps that are causing excessive wakelocks.

Other than that, I have Quantum 3.63 ROM with QuantumKernel 3/16 installed running with intelliactive and row.
