Bad battery life on CM13? - ZenFone 2 Q&A, Help & Troubleshooting

Hi everyone
I've just flashed CM13 (7/6 nightly build) and after a few hours, the battery drainage is noticeably faster than stock LP or even stock MM. Is there any thing I can do to improve my battery life like underclock CPU, etc? After 1 hour from 36% it went to 15% (when I post this) with wifi and screen on.

As I've been reading so far, the average SoT for CM is 5 hours.

Poor battery life 4.2.2

I had been running rooted 4.1.2 on my sgh-i747 for a while but I decided to upgrade to 4.2.2. After I tried a few roms i settled on JellyBam. The battery life has since been horrible. I am a fairly light user, and after a full day my battery was always around 75%. After 4.2.2/JellyBam I'm lucky to see my battery above 50% at the end of the day.
The battery stats look normal, I have most of the extra battery-draining features turned off, but my battery life is still pathetic compared to 4.1.2. The battery drain was the same when I tried out the latest MIUI, but I haven't had any other roms installed long enough to test their battery life.
Any suggestions?

Flash a different kernel and check the thread of said kernel for battery saving settings. I'm on 4.3 and usually sit at around 60% after an 8 hour work day and moderate/heavy usage.

How's your battery after 6.0?

So I also run an Moto X pure and love the thing. After Marshmallow dropped for my Sammy s6, I decided to switch back and try it out. I wanted to know how yall's experience has been and if your battery has been noticeably better. I switched to the Moto X Pure for the better battery life as my s6 seemed to only last me half a day of use at work. So how's it going?
I think the battery life is just as awful as it was on Lollipop. Doesn't seem to be any improvement there. That's just my opinion.
Standby battery has definately improved, screen on time has not changed that much
I had better battery life on 5.1.1 Screen on time is worse on 6.0.1
GF is running MM and complaining about battery life compared to LP. I haven't tested it or logged anything, just anecdotal from a heavy screentime and data user.
Hello guys
On my S6 Device idle takes 18% and cell standby takes 16% i think this is too much, can someone help me?
It for sure is a battery drainer... I just have the MM 6.0 on the phone and no apps whatsoever and with it just sitting there on the table with the phone doing nothing in 20 minutes it was down to 79% from being fully charged. I could go all day at work with phone in my pocket and after a 12 hour shift I would be at 93% battery on 5.1.1. I just can't leave my phone plugged in 24/7 because I might have to use it. I am going to install facebook and see what 20 minutes will do to my battery life. Sure enough it went down after install my battery was at 65% from 79% and now its at 45% with less than a half hour of facebook. so I figure its about a percent per minute ratio so my life expectancy is about 100 minutes with 6.0 on a fully charged battery.
Nice improvement for me. I never had much more that 1- 1.5 hrs SOT before getting about 15% battery. Now I see the same SOT time but have 50% battery left.
That's enough to get me through the day now.
I was jonesing to get the S7 as soon as my upgrade is do. Now I'm not so sure.
I'm feeling the same. I'd be loosing the IR blaster if I upgrade to the S7 and it's come in handy too many times to live without. My battery life has made living with the phone a more pleasant experience.

whats your battery life like?

I got stock os with all the fancy stuff disabled.
My battery charges 1% per minute when between (0-85%) after that charging slows down.
It doesnt however fully charge it usually wont go higher than 97%.
Battery drains 1%/h in standby
5%\h listening to offline-music
Today I had 6h 5 min with 3:54 on-screen time ( starting from 93% down to 2%.
About the same for me but I can do a full charge in 45min coming from about 9%
About the same, recent CM builds are better. I'm considering the Nexus ROM

At first i thought the battery life was ok, then i switched to the nexus rom for a while and came back to stuck because i wanted my camera back. There is a huge difference in battery life as far as I'm concerned. Stuck OS burns way more battery when idle but then again it has a lot more bloat :/ so it's to be expected
I get awesome battery life. On rooted stock with third party launcher with various tweaks. Way better than my desire or Moto g or Moto x or nexus 4 ever were.
Agreed, all other roms besides stock get awesome battery life. I've disabled or uninstalled as many apps as possible and the battery still drains unacceptably fast at idle. If we could get a stock rom modified to get the battery life of a custom rom that would make this phone perfect for me.

I consider the battery in mine to be working very well and use ~33.3% every two hours with the screen at full brightness and constant touching for reading. So looks like its about the same.
Standby is ~50% used in 48 hours with wifi on and background apps using the internet.
That's based on the apps I use and whatever they're doing in the background to wake the cpu, use wifi, etc.
Stock rom with the 'fancy stuff' disabled as well.
