[GUIDE][UPDATE] Try the battery tweak with Myn's RLS3!

Battery tweak can be found HERE:http://www.mediafire.com/?xmjdd797f6v2m90
Tweak can only be used with No HAVS kernels (recommended kernels below)
What is the battery tweak exactly? More information in this thread:http://forum.xda-developers.com/showthread.php?t=810940
The intended scope of this thread is for people having trouble with Ksoft consuming too much CPU resources
DO NOT USE WITH SETCPU!
Ksoftirq is something in the kernel that manages requests to the CPU. That means some device in your system is sending the processor a slew of IRQs so that the softirqd for your processor is being consistenly woken up, which ends up using most of your CPU cycles, thus sucking your battery life and performance. As indicated before, anything with a "K" in front of it is referring to the kernel. A kernel is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components).
When the ksoftirq is using such a high percentage of CPU, it is causing your CPU to work harder and doing two things that we dont' want; taking away from performance and draining the battery.
As it stands now, we know that depending on what kernel you're using it is going to determine whether or not you have that problem in the tweak. We know that it is not an app that is sending processes to the CPU that is causing the problem.
Don't fret if you read through this thread (http://forum.xda-developers.com/showthread.php?t=810940) and flash 1 of the 2 kernels known to work and it still shows ~30%, you're probably just not doing it right. You cannot simply just flash a new kernel, because as said before, the kernel is the link between software(battery tweak) and hardware. Therefore you must have the new kernel in place, then go about flashing the battery tweak. That way it is installed properly by the proper kernel.
As of now, there are 2 known kernels compatible with this tweak:
STOCK HTC 11 kernel, modded: http://www.mediafire.com/?i7u103j9xqnaw3s
Netarchy NoHAVS kernel: http://forum.xda-developers.com/showthread.php?t=719763
**Scroll down and you will see NoHAVS kernel by request, I have had better luck and amazing battery life with Netarchy's kernel
Instructions:
1. Open terminal emulator, type su. You will be prompted that you have gained superuser access
2. Type batt-cfg, then press 1 and then enter when dialog comes up about having root access
3. Choose option 4 to Disable battery tweak, then 9 to save changes and exit
4. Type batt-rm.sh, follow directions to remove tweak (It will tell you to choose y/n, choose "y"
5. Reboot your phone into recovery and install new kernel from zip. When that is finished, install battery tweak.
**It is ESSENTIAL that you follow these first 5 steps in order or I promise you that you will have the same ksoft issue over and over again**
6. When you reboot your phone, go into terminal emulator and type su again.
7. After gaining root access, type batt-cfg. Choose option 1 and save changes and exit.
8. Make sure that phone is unplugged from computer/wall! This is very important, having the phone plugged in will not show the ksoft process so you will not know whether it is still a problem or not.
9. Type top "-m 5 -n 1"(without quotes) This will show you your top CPU processes. You should see no abnormally high percentages for system or ksoft particularly. What percentage you see can depend on your current battery life when you run this test. Make sure that your phone is not plugged in when running the test! Also, take note of your battery life.
Tweak Will stick after reboot. You do not need to re-enable it.
If you install system monitor, you will be able to monitor the cpu level. When I am not touching the screen of my phone, it shows 245mhz. When I start moving the screen or etc, it hikes up a little bit. This shows that the tweak is working properly.
I have gotten incredible battery life out of this with very heavy usage(facebook, texting, phone calls, gps, pandora, running command prompts, etc).
Until something new comes around that I am sure will give me equally as good or better performance and battery life, I will not be switching ROMS/kernels EVER!
ROM: Myn's Warm 2.2
Kernel: Netarchy NoHAVS
Sidenote- I have just as good of performance and speed as I did while having CM6 with Snap7.6&turbo enabled, so don't think that you are sacrificing any performance.
Hope this clears up everything for everyone!
UPDATE-
There has been much debate as to whether or not this tweak works or not. I should have been more clear in the original post. Ksoft is still a necessary process, however, when I said that the purpose was to elimate the "ksoft problem" I was meaning that it should not be detectable by the CPU when you run the "top -m 5 -n 1" command. Neotelos_com made a very good point that is necessary to understand this tweak, "ALSO, this tweak lowers the CPU speed as the battery drains, so within the first hour you will notice the most battery drain." This means a few different things:
-Depending of the charge of your battery when you run the top 5 command, you will see different percentages of ksoft. For example, if I run the top 5 command right now, my battery is at 30% and ksoft doesn't even register at all. Assuming that I charge my battery full and run the top 5 command in the morning when my battery is fully charged, it will register as a process. Ksoft in the low ~20% is completely normal with a full charge. IT WILL BECOME LESS LESS AS THE BATTERY DRAINS.
-I have been toying with this in the very little free time that I have had the past couple days and have also discovered a few other things. Programs like Ultimate Juice, Juice Defender, and Tasker used in coherence with the battery tweak will improve a already great mod to give you significantly more battery life than before. the main reason being that 90% of the time your cell stanby is what is draining your battery the most. Those programs will turn off your mobile network when you are not using it saving a TON of battery power.
I will be posting screenshots at the conclusion of my testing either late tomorrow night or wednesday around 12ET. I want to be able to provide everyone with the info that they need to be able to get the best life out of your battery possible.

It depends what percentage of CPU it is using; in my experience it had been 20+ percent every time when I had the problem.

Is this good or bad? I would guess bad if i'm reading it right.

Yes, do not use this with SetCPU. It is unnecessary and will cause conflict as both are going to be scaling your CPU.

It will be different for everyone based on usage, quality of service in your area(how hard your phone is working to give you good service), and a number of other things. I can't tell you exactly how many hours but I can tell you this...after configuring this battery tweak correctly, battery life has nearly doubled. It's only been one day, but to this point I am extremely satisfied and never looking back. I will report further on this in the future and provide screen shots of my battery usage and Juice Plotter graphs.

What ROM are you using?

OK for clarity are we suppose to have one of those kernels installed before following the instructions or only during step 5?

It doesn't matter what kernel you have originally, just make sure that before you flash the battery tweak you have it completely disabled and removed and use one of the two suggested kernels when you reflash the tweak.

Im getting "batt-cfg: not found"

You must not have the battery tweak flashed. You need to go to the forum and find the original thread of the collin_ph battery tweak and get the zip file and flash that separately and after flashing the kernel.
Sorry, this was a quick write up and I left out some information for people who weren't familiar with what the battery tweak is exactly.

Mine still shows ksoft.

heres the post to the updated one FOR THE ERIS, NOT the evo, BUT it has more features, and the creator is in the thread, lots of info about different settings, how things work and so on..
http://forum.xda-developers.com/showthread.php?t=784089
i think i found out all the bugs from this tweak, there may be more, but i think through about a week and a half through my own trial and error, ive found out everything and whats going on. If working correctly (NO KSOFT), you can achieve great battery life.
hopefully the coder from that thread will update the battery tweak we use to include the temperature mod, since my phone overheats and could really benefit from that feature.
if you wanna be more customized, i recommend choosing option 3 and setting it up your way.
heres what i set.
i left it on underclock
i left the governor alone
i also chose deadline instead of noop.
Min cpu- 245000
max cpu 768000
for polling, instead of 60, i used 120 and instead of 15 i used 30,
then when it gets to cpu usage when battery is low, i choose 28 instead of 33.
you can change these numbers to your choosing, but with these above, i noticed no performance issues and everything seemed normal, just with extra battery life.
but with all our heads together, we can work everything out and get this tweak perfect...

Not working. Myn 2.2 netarchy noHAVS kernel. Showing 28% k...irq

Go into terminal, run "top -m 5 -n 1" (without the quotes) and if you system says anything more than 20% the tweak is not working correctly.

**HOW TO MAKE YOUR BATTERY LIFE LAST** Members Tips & Tricks

I just wanted to start a thread where all members can give tips and tricks on how to make our battery last longer. I know there is a “How long does your battery last” thread but we can just post here to help all members alike. Please post if you are permarooted, type of ROM, type of Kernal you are running. Please post the apps and setups you are also running to achieve this type of battery life.
Here’s my setup
S=off (permarooted)
Iced Glacier v1.11
Gorilla v.05 kernal
Oc’ed @1.4ghz
Screen Brightness set to 40%
Data sync every 1 hour
WiFi on, GPS off
The ROM I am on came with all the bloatware erased, so it was perfect. If you are running a stock ROM, first thing you should do is remove them. I then installed a app called SuperPower (dev. By a XDA member) which really helped a lot. You can setup times where you can have data on, wifi on, sync, screen brightness. Next install setcpu, this will help you overclock your cpu but more importantly, underclock your cpu. Heres my cpu settings.
Running: 1401/368
Screen off: 368/368
Battery under 50% 768/368
I also stopped using Advanced Task killer as I read it does more harm then good. Hopefully this thread will help out all members with their battery life!
Some screen shots I took. It shows what speed I'm running and it also shows that I have been off the charger for 15 hours and still have 45% left.

how do you set up data to sync every hour? and what theme is that?

That's one of the features of SuperPower. It's a great app, even if you're not rooted.
Personally, I'm rooted but haven't installed any custom ROM or kernel; still, just having SetCPU underclock the phone when the screen's off is a huge savings, as well as SuperPower's ability to turn off wifi when it's not in use.

I set it up in SuperPower. I'm using the Ice Glacier Rom with Launcher Pro Custom Docks

Great thread ! I like the idea of under clocking with screen off. But doesn't your display account for the vast majority of your battery usage? It seems like lowering the brightness would be the absolute best bang for your buck. Further, until the other items become a significant percent of your battery usage, you might be splitting hairs. Anyway thanks for the info, ill be downloading that app

I'm running iced glacier. Rooted with gorillas v.05 kernel. My battery last about 8 to 10 hours with heavy use. 5 hours of continuous use. 12 plus light use.
Setcpu:
Performance governor
1.7max 245min
Temp over 104° F
806max 245min
Screen off

Autokiller
Ultimate preset
Screen
Brightness/Auto
Timeout/15seconds
No animations
No rotation
Sync/setup to my liking, no baterry savings here
6ps, wifi, bluetooth, location
All of unless needed
I charge my phone for 7 plus hours everyday. Since I can't shut it off without booting into recovery, I can't really charge it off, which is how most tutorials recommend you calibrate your battery.
I've noticed that wiping battery stats in clockworkmod recovery actually decreases battery life. I recommend simply charging the hell out of your phone when you can. I know I know its bad for the environment... SO IS PLASTIC! Lol

When I first flashed clockwork everytime I rebooted while the phone was plugged in it booted into recovery, but not when it was unplugged.
I read somewhere that reflashing clockwork helped fixed this so I reflashed it in rom manager once with no result, reflashing it a second time fixed the issue and my phone hasn't rebooted into recovery since.

and does turning on the usb debugging also help, for real for real?

De-Sensed Iced Glacier 1.2
Gr8Gorilla OC/UV Kernel 1.02: 806/245 On Demand Scaling (Only turn it up to game/bench/show off )
LauncherPro Plus: 7 Screens, 10 Widgets (4 are full screen, 4 of them update every hour)
All apps and games (including the big ones like Angry Birds, Pocket Legends, etc) are moved onto the phone, instead of sd
No Live Wallpaper
Brightness at 30%
Auto-Sync every hour with Facebook, Twitter, Google
Wi-Fi Calling (If you don't use this, you should! A constant connection with a wi-fi network is better than constantly searching for signal with the radio. Great battery saver for home/school/work.)
With this setup I haven't had to put my phone on a charger until the end of the day. Ever. I use my phone for a music player when I deliver pizzas and when I get home I have at least 60%. That is with the music, phone, and gaming during down-time (if I'm lucky ). Then I can play away when I'm home with no worry of plugging it in until I go to bed.

^^ great tip IRIS! I'm gonna start using the wifi calling when I'm at home. I live in the crappy area where it's constantly switching from edge and 3g. I started using the phone with heavy usage and I'm getting around 15 hours. I have the settings, updates, sync to my liking. I'm with crx on this one, use the phone!! Just charge the help out of it when you can

Hey Lakeshow423,
Regarding the screenshot in your OP, is that power control widget from SuperPower, Iced Glacier, or some other 3rd party app?
Thanks, and sorry for posting off-topic.

USB DEBUGGING ON
Wi-Fi off
Locations Off
GSM/UTMA/HSPA Auto
Only FaceBook and Email update every 30 minutes (I only have like 30 friends on FB so it is a quick update)
All other updates are manual...
I get 30-36 hours on a full charge...

Not sure if anyone looks at this form anymore, but i'm running CM7 nightly build 23, i did a full charge and a battery wipe to see how long my battery lasts. I hammered it for a good 10 hours with OC with screen on (underclocked screen off) i played games, watched youtube videos and just about everything else and i was still at 20%

I once ran for 1 day and 9 hours with 45% left, and it was moderate use.. I was on nightly #19 for CM7.. it's not ever happening again for some reason.

heres mine from switching glacier to miui.

My battery drained to 20% in like 5-6 hours while on glacier even while doing nothing

I found a link early on in my battery problem days.... And I think that this actually does help a lot when it comes to getting a battery that lasts longer. Given its hard to replicate the procedure, because of the CW bug that boots the phone into recovery..but I just charged it while it was in recovery(or I think if you turn fastboot on and charge it while its off, it doesn't boot into recovery.) and my battery life really has seen dramatic increase.... anyways here is the link...
http://forum.xda-developers.com/showthread.php?t=712990&highlight=battery
Note: I do realize that its in the EVO 4G forum, etc...but the letter is from HTC, concerning HTC batteries...So I tried it anyways, and I can't say I haven't seen the effects.

Ill just be blunt...
Dumfuqs smartass kernal
Auto sync off
Background data off
Screen low
Market > my apps > menu > notifications > OFF
Either 4g only or 2g only
Only use 3 of the 5 screens
Minimal Widgets
Pick and choose which you like and/or want to utilize.
I usually leave background data on now so I can have cool green icons

I always wanted to know why this is the case? Roms don't control how much power a display is supposed to take, but why does IG show more than CM?

[Q] Huge battery drain from keep awake

Hey,
After coming home from school today, I noticed that my battery went from 95% to 50% with hardly any use. The battery kept training steadily and now its already to 15%. The signal is pretty ****ty at my school and I usually turn off wifi. I've never seen it drop this far, and according to my battery use android os has used 70%(more or less). Keep awake has been on for 9 hours out of 13. I haven't noticed any out of the ordinary apps or anything. I'll attach a few screens and would appreciate some help. (i9020a, over a year old if that helps any)

what rom are you using ??? i'm having almost the same problem in this day with all the jelly bean rom ... now i'm testing on ice cream slim4.2 and i colud have fixed the problem but i still want to test more .... i used it for about 10 hour with almost 4.5 hour screen on viewing powerpoint files with no sim but almost always in wi fi and i downloaded 3 torrent files ... and it still has 31 % left ... i think it is very good ... i'm using conservative 1000-200 but i don't think it's governor related ... it just didn't go in deep sleep, don't know why ... i also switched to the previos radio (i'm on a 9023)
try to clean all your process by the built in app... sync off... make an all night charge and install cpu spy to see what frequencies is use and if it use deep sleep ... if it doesn't there is your problem ( still don't know how to solve it just try and try, i restored backup , do factory reset wipe and nothing did work... now a miracle ... i'll post my results im my thread when i'll finish all my test in some days ... )

Some people reported that copying everything from your SD card to a computer then formatting your SD and copying back everything seemed to fix it. Format the SD from your computer though, not from the phone. And run an error check just in case.

we should use Fat32 right ??

In almost many cases, the battery drains due to ROM. The framework with one of the xml file values is found to be mostly the reason if ROM is the culprit for such drain...Some devs keep these values on higher side in Framework to reduce the response time..
You should change the ROM to something like ParanoidAndroid 2.0, which has been proved to be a battery saver. I have also experienced that this ROM really saves battery after ICS 4.0.4 Stock...
You can follow other things like;
1) Change the Settings -> Developer options -> Background process limit to At most 4 processes.
2) Keep location services off since these services take off a lot of processor/battery. You can switch them ON whenever required.
3) Reduce the minimum CPU Frequency to 100 MHz (Be Cautious! - This is development thing)
4) Use minimum screens on Home and also minimize the number of widgets.
5) Keep NFC Off and Set the Network mode to Manual.
6) De-activate keyboard vibration in Language & Input settings.
The above things will make a big difference to the time of usage without charging....

i'll try paranoid in a future ...
today for the first part of the day i had my usually drain issues ... i tried a bit, rebooted etc but nothing seem to work ... it just didn't want to go in deep sleep mode and the android os was always working, i think it could be app related, i closed more then once all the app running and cached, then i uninstalled opera mini and deleted airdroid data and after that it apparently started to work again without battery drain and i came home with 10 per cent left and 5 hour screen on ... my next step is to format the sd ... i don't think those two app could make this bug ...
anyone has some suggestion to make deep sleep work ???

[Q] How to Get Amazing Battery Life

Hey everyone,
Lately I've been in the works of trying to get better battery life, as I only get about 2 - 2.5 hours of on screen time. I've seen other users get anywhere between 5-7 hours. I do use facebook, and have uninstalled the official facebook app for the friendcaster one, but have yet to still hit anywhere near that amount of time.
Out of curiosity, and hopefully future reference for other users, what are some great ways to boost battery life? Do you use apps? Uninstall software? Please, do share!

Manually controlling screen brightness was the biggest increase for me. The other one that helped was 2g data when i turn off the screen.

Freeeeze apps with Titanium Backup. You wont miss anything neither you loose perfomance, no you gain.

Change notification updates to suit your needs. Stuff that you don't need to know right away, lower frequency or turn to manual. For instance:
- Change weather updates to every 1-2 hours, unless you really need to know that it changed by a couple degrees as it does.
- Decrease facebook notifications (big one. If you use it a lot, then keep it high, but realize that this WILL drain battery.)
- Manually update stocks (again, if you don't need them instantaneously)
- Blog & News apps usually set notifications on by default, disable or lower frequency on them
- Lower screen brightness
- Turn display to auto sleep 30sec-1min tops
Note that while some of the notification controls can be found within the system settings, many apps will require you to go to their individual settings to adjust them.
All depends what you do with it. Navigation, internet, talk time and intense games all suck up more battery. That doesn't mean you shouldn't do that stuff, but it's just the way it is on any device.

Simple, root and install CPU sleeper, that should give u a lot of battery life.. at least that's how I do it and today I unplugged my phone at 10 am and its 9:25 and I have 65% left

Almost all of em are running on custom roms I beat and I'm the one you said that with 5 - 7 hours screen time everyday. There are many things to do to maximum the battery performance and first thing is root and unlock your phone and flash a custom rom. If you are on stock rom, it would be almost a no go.
1. Flash ViperOneS 1.2 rom or One maximuS V2.5 rom, they are the best sense based rom with the greatest battery performance I've seen.
2. If you don't need sense, flash cm10 or aokp. They should give you more battery because they aren't as resources hog as sense. However, you couldn't use sense UI and access to the dedicated image chip in camera.
3. Turn the brightness level down to as low as possible, this is the major battery killer.
4. Switch to 2G when you are in standby mode. Disable fast dormancy, it will save you battery in standby mode at the cost of connection speed when you surf web it will be slower but it does save you some battery in standby status. You can disable it in ViperOneS's tweaking but you'll have to do it manually in all other roms but that is very very easy. Personally, I let it on because the 3G speed isn't good in Hong Kong, too many iphone/android everywhere here, over crowed. In every street in HK are messed up by SGS3/Note/Note2/Iphone, think about how horrible it is.
http://forum.xda-developers.com/showthread.php?t=1684604
5. Turn off wifi when you don't use it, disable max performance in wifi setting. Turn the auto-sync off when you don't need it too.
6. Just remove all apps and bloatware you don't want. When you flash ViperOneS/maximuS 's add-on, you will have a list to do it.
7. Some bloatware will still be there after flash the add-on. You have to download systemapp remover to del those apps.
8. Some apps like to run as services mode and they drain battery in background like youtube, google map, playstore. You need to download AutoStarts and force them to disable as an auto-startup services after bootup.
9. Download Systempanel and check any non-system apps running at services mode in background. Force them stop in control panel. I only have four non-system apps let them running as services like whatsapp.
10. Don't run too many widgets, I only have two widgets on. Don't use 3D wallpaper.
11. Use opera mobile to surf web. The stock browser and chrome should faster but sometimes they drain battery real quick.
12. Turn the cpu mhz down when you are just doing some normal/easy works because the stock kernel has very suck governor performance(only ages governor: on-demand, save battery, max performance) and drains battery fast. Turn the cpu mhz back to high level only when you play games, this will save you great battery. Don't worry S4 CPU is still very powerful even you set it to half speed. You can flash custom kernel if you don't like to turn cpu speed up/down, they introduce more efficiency governors to handle it automatically but all 3rd kernels are likely to have some bugs at this time. There aren't many active developers out there.
13. After a heavy or long using like a full battery cycle, reboot the OS to clean up the cache/memory leak.
14. Use nova launcher or apex launcher to replace the sense launcher.
Well, I basically do ALL the stuffs above and got 5 ~ 7hrs screen time. Today, I do surf the web like mad(4hrs), 1hr 720p movie(software decode in MX Player as it's a rmvb movie), 30mins+ music with poweramp. Guess what? I got exactly 5hrs screen time and 1% battery left when I get back to home, very lucky though. I think my usage is a bit high today, normally I have 6hrs screen time average.

A lot of people on stock ROMs can get that sort of battery life too.
This is mine on stock:

Also wrote a quick guide, pretty similar to the above:
Terminator19 said:
Leave "best wifi performance" turned off.
Disable any apps that you don't need in settings>apps>click on app>disable at top right
Don't have weather etc. syncing every 30 minutes etc. set to something like 2 or 3 hours.
Manually control the screen brightness as auto makes the battery life worse, install qbright from the market and set a gesture so when you swipe up or down on the homescreen or dock icons this app is opened like the below:

"lightbox_next": "Next",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I have it set to currently; night is 0%, indoor 30%, outdoor 50% and sunshine 70%
Keep wifi on as much as possible and set to never sleep
Keep GSM mode selected instead of WCDMA in mobile network settings as one; the voice reception is stronger and better battery life even when connected to wifi I found.
If you aren't going to be using any internet at all for quite while (meaning no need for weather, emails to sync etc.) then turn wifi and mobile network data off.
Only enable WCDMA when you want to browse or stream something (only when wifi is not possible)
Don't use any form of a task killer, if an app isn't responding just use the built in one.

WOW! Thanks guys! I'll definitely be trying these tips today.
Lets keep'em coming!

I'm running CM10 and all I did was lower my CPU clock to 1134 and I get great battery life. I also try to keep my wifi off as often as possible. I have auto-brightness and auto-sync on and usually get 6-7 hours and don't have to charge it all day. I prefer being able to use the better governers on top of the decreased frequency, but I haven't been able to get the Fusion AOSP kernel working on CM10 for quite some time.

I've always thought about under-clocking my CPU. I'll give that a try too. I'm sure i don't need the full 1.5ghz. I'll play around with them and see which will fit my needs .

My battery lasts twice as much just by turning the mobile internet off. I turn it on only when I need to surf the web/sync my apps and turn it back off right after.:victory:

Change governor to smartass2 and set your max CPU frequency at 1ghz. Also you can install app called llama for profiles switching and battery saving.

Inaccurate battery monitor?

Nexus 5, 16GB, MRA58N (stock, not rooted)
Anyone else notice that sometimes the power percentages shown for each process in the battery monitor do not add up to the total battery drain?
I am finding that sometimes they add up to within 1% of the total shown.... and sometimes they are WAY off with as much as 30% of the displayed battery drain unaccounted for.
Since I don''t have access to the battery terminals, I can't determine independently whether the percentages shown are simply inaccurate, or whether there are missing processes (ie., processes not shown at all in the battery monitor).
Paul

Further on this..... here is a screen shot from today. It was pretty accurate until I left the house for several hours. At that point (and accompanied by less than stellar cell signal levels), the battery drain increased significantly as expected with lower signal levels but that did not seem to show up on the usage stats.

I know this does not show all the entries, but the rest of them were between 1% and 2% and the total added up to about 30%, not the 70% drain shown in the graph.

This has been happening since the first Lollipop release. Not only on the N5, but also the N7 2013. There isn't a known fix, but for what it's worth, I think it's radio related.
Some days I seriously consider going back to KitKat, I miss 0.2% drain per hour overnight I could consistently achieve with it. And I didn't have to reboot twice a day to stop the stupid drain. It was just better. I think Lollipop was rushed, and it's been a ****show ever since. The other day, I even went so far as to download SlimKat v9 stable, still available on their website.

Ah, good to know it isn't just me. Your suspicion that it is the radio makes some sense.... when it happens to me it is usually after transitioning from WiFi to cell data and with a sub-optimal signal level.
Did you say 0.2%/hour on KK??????? Please elaborate! Best I could ever do was about 1.2%/hour and that was after a LOT of optimization. But that was on my 2013 Moto X. I replaced the Moto X with the N5 when Motorola abandoned us on 5.1, which made my Moto X very unstable.
Is 0.2%/hour possible with KK on a stock non-rooted N5 with no apps updating in the background but with BT, cell and WiFi on and sitting idle on WiFi? What revision level? Or does that require root and Greenify? If anything close to that level can be had on stock I think I'll try flashing it. I had no other issues with KK, I don't mind setting my phone up again and there is nothing except doze that I will miss on MM (so far).

Actually 0,00%/h can be achieved on LP and probably on MM too.
A couple threads to give you clues (and proofs ):
http://forum.xda-developers.com/android/general/guide-0-0-hour-idle-battery-drain-stock-t2973588
http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884

Ouch! Reducing my standby drain has been a mild obsession with me but the steps on those sites are way beyond what I'm willing to devote to it
Just for grins I flashed KK 4.4.4. Too early to tell for sure, but while my standby drain is not quite as good as I can get in MM with Doze active, it does seem to be more consistent and the various battery percentages in the monitor did add up to the total reported drain. Lets see if this continues. If so I may just leave it on KK for a while. Now if I could only find a way to get rid of the "System Update Available" notification.....
Sooooo nice to have a phone that allows easy flashing of any firmware I want!
Paul

It just dawned on me what you all (I think) have been talking about.... the cell or WiFi standby current suddenly is significantly more than the nominal level that is used to calculate the battery percentages. Right? I have always assumed the battery percentages were MEASURED, which is why I was puzzled by the fact that they didn't always add up correctly. But from what I read, they are CALCULATED based on an ASSUMED nominal consumption (unlike my laptop, which actually measures and integrates charge current delivered and discharge current withdrawn). So what I have been reporting in this thread is probably the same "cell standby" issue everyone has been talking about..... and that I didn't think I was experiencing
OK, I get it (I think). Now that I am happily reverted to 4.4.4, I think I'll wait a couple days and see if people start reporting that it is fixed in 6.0.1.
Paul

@Primokorn
Thank you for these links. I was aware of the existence of Amplify, but had never used it. I tried it, and while it did help curb the wakelocks and alarms, I don't think they are the problem. BBS never reports any runaway wakelocks when I mysteriously lose 20% overnight on Lollipop and Marshmallow.
@pgoelz
I apologize, I meant to reply earlier but got busy. Back when KK was new, the only thing I used was Greenify. I used device only location, on 2.4GHz wifi, sync on, with little to no cell signal. I don't think you really need Greenify though, it's kind of outlived it's usefulness You just need to avoid garbage apps like Facebook.
Anyhow, I flashed SlimKat v9 stable, ParanoidAndroid KK pico gapps, and franco.kernel v63. Pretty much what I used to run back in the KK days. I did eventually switch to code_blue kernel, but the last KK version sometimes caused apps to freeze. I wouldn't use stock ROM and kernel on KitKat. But if you really want to, there are ways to disable the OTA popup. You can use Xposed and Gravity Box, or I think there are also some files you can delete. But you don't really need GravityBox with SlimKat.
I was also on the KK KTU84Q bootloader and radio, but my signal wasn't good enough, so I flashed the 6.0.1 radio released earlier today. Currently running the above ROM/kernel with MM 6.0.1 radio.
Now all I can do is install BBS and wait.
6.0.1 is an update that adds emojis, some weird tablet layout, and a few security fixes. Nothing else.

Thanks for the heads up re: 6.0.1. I think I'll stay on KK for the moment. Battery life isn't as good as it is on MM when doze is dozing and cell isn't draining, but it seems more consistent and predictable. I'll wait for 6.1 to be released. Maybe I'll take a side trip to CM land in the mean time.....

My first night running it got me 0.3% drain per hour. Are you running social media or chat apps? Also, I would recommend giving my setup a try if you're feeling patient.

No, I don't run social media or chat apps. With the exception of calendar and contact sync, any other installed app (mainly Email) is set to manually sync and where possible do NOTHING unless I am actively using it. My concept of a smart phone is that I want a smart phone when I am looking at it and a dumb phone (phone calls and texts only) when I am not. I'm trying to get back to the week of standby I used to get on my last flip phone
Marshmallow and doze get me there and would be even better if we could disable the motion sensing part. But whatever issue is causing my sporadic battery drain (that does not show up in the battery percentages but DOES sow up in the graph) negates that.
I do not plan on staying on KK long term so I'm not sure it is worth the effort to go through your setup but I may get bored at some point and give it a try. Hopefully, the battery drain issue will get fixed soon and I can go back to MM. Or maybe CM13 will be the answer... I have read suggestions that it might allow some customization of the doze functions.
