Anormal Battery Drain - Galaxy S6 Q&A, Help & Troubleshooting

Hello guys,
I have noticed some Battery Drain in my G920F since I have changed the stock kernel for Arter Kernel (I'm on Stock 6.0.1 rom).
But I don't think that Arter is the problem, I will explain to you :
I have migrated to Arter Kernel and the battery life was great (better than stock) but since some days (after 2-3 month of Arter) my battery does not take long, I need to charge my battery 2-3 times a day ! And I do not use it often because of my studies. I have checked the battery settings and the first battery utilization is the screen, I have calibrated my battery with this app : https://play.google.com/store/apps/details?id=com.nema.batterycalibration
But nothing works !
Someone has a solution ? Maybe I have to change my Rom ? Any advice for a fast Rom and good battery life ?
Thanks in advance !

[Q] franco Kernel milestone3 -battery life increased

relatively a noob with this stuff... first time poster...
so i just updated to franco kernel milestone3 via the FK app.
I'm running liquid toro v1.25 on a verizon Gn
I just bought a new battery and was priming it ... I drained fully, charged, and I'm on my second cycle of draining the battery.
I decided to update my kernel and did so through the FK app. worked great (hats off to franco and the community)
So once it updated and rebooted.. I notice my battery life went from 23% to 53%
not complaining but wondering why?
Did me updating the kernel affected the battery somehow
or is the kernel that much better that it's draining that much less
thanks-

Lollipop AOSP Battery Life

I've had 0,3-0,5% battery drain per hour (in standby) on stock 4.3 Jelly Bean. After update to KitKat, my battery started to drain faster and it was somewhere around 1,0-1,5%/h so I downgraded back to the Jelly Bean and all was normal again. Now, I updated to 5.1.1 AOSP Lollipop and even with everything off and all battery friendly settings, I'm experiencing exactly the same issue: 1,0-1,5% battery drain/h. I've made a new record with 14,5 days of battery life with light use (on 4.3) and now it's not possible to go over 4-5 days in IDLE ! I've made a factory reset/wiped everything. How is it possible that Lollipop causes me this battery drain when Jelly Bean didn't do it ?
I monitored my battery with wakelock detectors for 3 days but there is no wakelocks and device is (as apps said) in deepsleep most of the time.
Any suggestions ? I like new system but with this terrible battery life it's really annoying.

Terrible battery life would be less than 10-12 hours for me with mixed use. What do you use your smartphone (more like pocket computer nowadays) for anyway? 14 days of standby probably means not touching it at all, so why bother switching it on?
lp make more use of battery and processor , the only thing that I can do, to got a good time of battery is turn off all animations , in the OP you say "AOSP" you use a rom? the last build of alberto have battery drain , y recomend aosparadox is really cool
@davider222
I also want a great battery life. Do you know where can I download Android 4.3 for Moto G ? Beacuse I can't find any .zip costum ROM or Motorola ROM.
@Eurofighter_ty
you can't downgrade from 5.1 bootloader to older 4.3 bootloader because you will probably hardbrick your device but here are some links from xda
[GUIDE] Moto G - Restore stock firmware
All KitKat and Lollipop firmwares
@STR4NG3R-GUY
I have 20150909 version, it's also impacted by battery drain ? I have just tested GPS and it consumed only 13% of battery during 6 h long bicycle trip so I'm experiencing only stand by battery drain, normal use is probably fine
@davider222
if you have that issues , why stay in lollipop ?, downgrade to kitkat :3

Which kernel do you suggest for BEST battery life on G920F?

I've tried some of the kernels which are produced for S6 (G920F) in xda but after a while battery life gets worse and worse. It sometimes gets so bad that while screen is off (just music plays) battery level decreases and I can't understand the reason from the "Battery Usage" screen in settings. I know, it's related with both ROM and kernel, but I'm using Alexis ROM (and arter97 version 20.0) nowadays and I love it. Can you offer me the best kernels about power efficiency?
I'm using arter's kernel v20 too, but with Xtestrolite ROM and have quite a good battery life, playing Spotify all day and doing moderate browsing.
Do you find Alexis ROM better for battery life? Haven't tried it yet.
It's not worse than XtreStoLite ROM but I can't say better than it. How many hours SOT for you? Can you upload a screenshot here when your battery is at %1 or somewhere like that so that I can analyze how is your usage and is it efficient.
I can only do it on Thursday tho, got no time until then. Will edit once I get the screenshots. Also, I'm on Xtrestolite 3.2, not latest, too lazy to update.

Best Battery Saving ROM/Kernel for Galaxy S7(G9300) Qualcomm Edition?

What is the best ROM for Galaxy S7 G9300(qualcomm) in terms of battery saving.? I have used 'Aurora v24 s8-port', 'Norma v6 s8-port' and 'Aurora v25 S7edge-port' on my G9300. But none of them satisfied me. Specially S8-ports are drained battery super fast even everything are off with Battery saver on. S7edge-port battery backup just below average. Used 'Tomato v11' ROM too which battery backup average.
Now please recommend me which ROM/version i can use. You can suggest me how can i save my battery on these ROMs.
And another question, is "NOTORIOUS" kernel available for qualcomm version of S7? If not which is best kernel for S7 qualcomm in terms of battery saving.

In s8-ports based ROM i am losing 1% battery life in every 1.5/2 minutes while surfing internet using wifi with power saving enabled to MID. So it takes only 2.5-3 hours to drain 100% charge.
In others ports it last upto 4 hours and in offical rom it last upto 6-7 hours approximately if i continuously surfing.
So please help what can i do now.
Try Greenify.
