Rom vs battery life?

Hey guys, looking to find out which rom is best on battery life? I am using CyanogenMod 3.6.8.1 right now, and it's killing my battery as fast as I can charge it. Which ones seem to work best for saving the battery? thanks for the input!
not sure if cyan has removed the battery on the lockscreen on 3.6.8.1 but on his newer bulids on (3.9.7) he has removed the battery icon fromm the lockscreen and i must say the battery life has increased...i say go with his new build to save some battery power
I did, I flashed about an hour ago, so far doing better
I feel that 3.9.7 was eating more batter than 3.6.8.1 i went back to 3.6.8.1

Best ROM without battery drain?

What's the best ROM for battery life, with no noticeable battery drain?
Unlocked and rooted.
My current ROM (AICP) drains the battery right in front of my eyes. In 4-6 hours it's dead.

Most of the time it's not necessarily the rom, but the apps. Only things like network standby are rom-specific. Can you post pics of your battery stats page?

Extended battery Decrease in performance

Guys, I'm in big doubt. I have an extended battery perfine of 10,000mh while I play the game performance is horrible, many crashes and freezes that irritates me a lot. When I use the regular battery I do not have any kind of problem with performance. My question is battery extended influence mobile performance? I noticed that when I zero the battery and charge again I have a good performance. My device: LGv20

How best to calibrate a new extened battery for the Note 4?

I recently bought an extended 7500mAH battery for my Note 4 running RR 6.2 version AOSP ROM with their custom kernel. I am wondering how best to re-calibrate my ROM readings of the battery capacity. I have charged the battery to 100% and used an opensource battery calibration app on F-Droid. Is that enough? I find the battery isn't lasting well enough. Just getting 3.5 hours of screen on time now. But that's double the screen on time I got before this.
Is there a best way to re-calibrate my ROM for the new battery?

STANDBY BATTERY DRAIN

Whenever I leave my phone at night it loses about 20-25%, I am running AOSP extended ROM. I was also running Lineage OS 17.1 which is having poor battery performance. In LOS rom I lose about 30-35% at night. 20-25% in AOSP extended is also seems to be a huge battery drain. Can anyone help me with this or suggest me a good kernel for improving the battery life of my phone.
