For my individual phone I discovered that EC01 plus Juice Defender has drastically improved battery life. I will say previously with SuperClean that Juice Defender had a much smaller effect.
That means you have something that's using a lot of data.
Turn of Contact Sync
I've been using EB01 (not EC01) for about a month, and having horrible battery life.
Using the battery monitor (Settings->About phone->Battery use), I traced it to an internal process, sometimes called "Android Core Apps", also known as android.process.acore. I also used an app called "System", which showed that android.process.acrore was regularly pegging the CPU at 100%.
A little reading on the web suggested that it might be related to syncing of contacts. So I did a little experimentation and here's what I discovered:
- If I sync to ONE gmail account, it consumes battery pretty fast (about 5% an hour). If I turn off sync (but leave the contacts on the phone), it gets better, but not perfect.
- If I sync to TWO gmail accounts (for example, home and work), it consumes battery at a tremendous rate (about 10% an hour). If i turn off sync for both accounts, it DOESN'T GET BETTER. The CPU continues to spike and the battery life is miserable.
- To stop the drain, I had to BOTH turn off all contact sync AND erase the contact book. (Settings>Applications>Manage Applications->All [tab]->Contacts Storage->Clear Data). Then my battery life was PERFECT. Android.process.acore completely dropped off the battery use list. Of course, I have no contacts on the phone at this point, but my battery life is great.
My theory is that Samsung's custom andress book is really screwed up, especially around the "linking" feature. It just churns and churns, eating battery. It gets worse the more contact books you sync.
The next thing I plan to try (when I have time) is to export my gmail contacts to a file, and then import them into the local contact storage. I will try to de-dup them before hand. I'll let you know what I find out.

CORRECTION: I originally wrotet that this data applied to EC01. I am actually using EB01, not EC01. Message text above has been updated.
EC01 has only been available for a week or so... How have you been using it for a month?
My bad. I'm using EB01, not EC01. I have no experience w/ EC01, so can't comment.

Like the facebook widget. Delete the crap that's wasting data instead of crippling it partly while letting it continue to be wasteful.
I found JuiceDefender only hurt my battery life, and caused quite a lot of syncing to break (and use Push for anything that supports it... that'll cause its battery use to quickly approach zero, while getting instant updates, instead of 30min-multihour delay!).

Under Network Usage in Spare Parts there are a couple big spenders. Android System is up there no surprise but something labeled as "0" is by and large the most battery life costly. When I tap on it, Spare Parts force closes. I do remember having something named "1013" do the same thing on SuperClean.
Learned very belatedly that NoLED has been one of the big battery drainers for me, even on various versions of SC (NV). Also has been said in the past: sometimes things happen during a ROM flash that cannot be replicated when you reflash so this may explain why I kept restoring back to EB01 to have half a decent battery life until they started posting steps in Dev on clearing things out using ODIN Stock EB01 w/ Pit. Quite educational.
Juice defender is a placebo...it doesn't actually increase the battery life. If it did, Google would've applied that in default.
I have noticed that I don't receive pic texts while using juice defender because it turns off 3g. So I don't use it.

You probably never "adjusted" google talk, and set it to not sign in automatically..
And then there is that weird option at the bottom of the display settings.. disable that as well..
Also the news and weather application refreshes every so often, adjust that as well..
JuiceDefender helps with the phone in your pocket all day/no real signal issue..
If you turn your data radio off, the phone will still ring and your sms' will continue as normal both in and out.. see what the battery life is then..
Also (assuming that you are rooted) there is an excellent kernel, OTB 1.2 which would also allow you to under volt your phone..
But the above settings will help any fascinate if you have not already done so.

You'll still get text/calls, but not email/mms/gtalk etc. Text and calls use 1xrtt data and mms/email/internet/etc. use mobile data. I use a manual "juice defender" which is turning off mobile data in my notification toggles.

Disabled google talk auto sign in. Also disabled that power saving mode in display setting. The display option uses battery?
That is a suggestion. Going to see if that helps my battery.
Juice Defender has drastically improved my battery life. Rolling with EB01 radio + Community Rom 1.1
Issue is since it completely shuts off data I don't get incoming Google Voice texts. A shame since I use GV as my primary number.. I really need a better solution. I would even be happy with a thicker Fascinate if the battery life was decent.
I'll try EC01 and see if that improves anything.
I've had horrible battery life ever since the first Froyo leak. I've tried different Rom's, tried turning off certain things like wifi and rotate, and I've tried different radios and different kernels. I've also done the whole battery reconditioning thing and it hasn't helped either. My apps haven't changed since 2.1 and I was getting upwards of 30 hours on one charge when I was running DJ05. So, I have been trying to achieve that level of battery performance since then but with no luck until now.
I just recently followed Adrynalyn's directions in how to get to ED01 quickly so I could try out the ED01 radio. After having the ED01 radio and then flashing to the latest Evil Fascination Rom, I am pleased to report that I am achieving the battery performance I had with DJ05. Oh, I forgot to mention that I'm running the latest OTB TW Kernel by Nemesis2all and I'm not undervolting. I'm running at 1000 mhz stock.

awesome! just what i wanted to hear. I'll be flashing this tonight
Went through the fairly long process of getting the ED01 radio on my phone. Unfortunately I see no difference.
After 7 hours of being unplugged and with very light use I'm at 45% battery, similar to every other Froyo build I've encountered.
I have Beautiful Widgets and set the refresh to every 3 hours, but I'll try disabling it just to see if there's a difference. After that I'll get into some undervolting, then maybe the Evil fascination ROM.
Is there a way to monitor network traffic?
i dunno how everyone is having bad battery life.. ive been at work for 9 hours.. texting all day, n pissing around with voltage control.. and i talked to a drs office for 36 mins.. and im at 75% my brigtness is set to max... and i have full 3g service.google location is on, gps n auto rotate on all day.... ive rebooted my phone twice.. personally.. ide reflash and start over..

It might not just be the radio that's resulted in me having great battery performance. It could be the combination of Rom and/or kernel plus the ED01 Radio. I'm not sure. All I know is that after I went to the Ed01 radio and flashed Evil Fascination (latest) Rom plus Nemesis2all kernel, I am achieving outstanding battery performance.
I am only syncing once daily with SNS Facebook and Twitter. I have Weatherbug and widget syncing about every 30 minutes. Tweetcaster is syncing about every 15 minutes. Tapatalk and Foursquare are syncing about every 15-30 minutes I think. That's about it for me. I don't have too many programs syncing.
I would try flashing Flashing the Rom and Kernel I mentioned and see what happens.
I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated
Edit : phone idle consumed 40% :O
I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot
Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...
New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...

I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.
Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.
The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same
When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.
How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.
i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.
I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.
When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)
After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I use the same battery settings recently. I turn off GPS and Sync unless I'm using navigation. Which blur apps do you freeze? I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.

I monitor battery use carefully and freeze apps that cause unnecessary drain. I use 2g only. I use Better Battery Stats to identify wakelocks. Everything in my phone seems set up properly but I cannot figure out how to deal with battery drain due to a poor signal in my area. I have tried using airplane mode but this results in exchange/email, friendcaster, and gmail (among others) wakelocks. I have no issues with wakelocks on the two tablets I use when wifi is turned off but turning off data on the Vibrant seems to offer no battery saving benefits. Even when I turn off syncing completely, I run into wakelock issues. I'm using bionix right now but I have had this issue with many ROMs.
Bottom line: If I leave data activated, I get significant battery drain due to a poor signal. If I turn data off, I get significant battery drain due to wakelocks. How do you guys handle this problem?
Hi...
In my opinion,
1. you try diffenrent modem for optimal signal fetching....
2. Try Juice defender like apps that prevents unncessary battery drain to a greater extent, if it is PRO version, then it is worth like anything.....
3. Try some CPU slide or voltage control to reduce the battery drain...
After sincerely trying this for about one or two days stick on to the optimised parameters, definitely you will be get rid of battery drains.....
Dont mind me if it not much useful....
All the best...
Are you running the original Bionix?? That's old school stuff. You can try different modems to get better signal, but a bad signal will drain the battery no matter what phone you have. At least it has with every one of my phones. I would start at fixing permissions under ROM manager, reboot into CWM, repair permissions in there, reboot and see what happens. That has fixed app issues for me before.
But really, if you are still on Bionix, I would recommend updating to Fishmanmod's updated version of Bionix with a clean wipe. Could give and ICS rom a try, also.

I believe so. Even when all my accounts were set to manual, when I left data on during the day at work, the drain was out of control and there were no significant wakelocks. The email app I had been using was also causing battery drain when signal strength was poor. I used the aforementioned email.apk all day today with exchange set to push. I turned data off when I didn't need email or when my signal was poor (most of the day) and the email app didn't cause any wakelocks (it did before). After 13 hours (1 hour of display time), I have 65% of my battery left. BetterBatteryStats shows no significant wakelocks.
Hey guys, so ive had my nexus 4 for around 4 months now? might be more and the battery is just terrible, obviously we already know this as ive seen so many people post about it and such
my question is this, what do you guys use to save battery? Im currently on XYLON ROM with Perf-enhanced-Stock-422 kernel which isnt bad, theres nothing wrong with it in fact but i literally only get around 2 hours screen on time, terrible i know
ive heard people say flash android 4.2.2 and then flash a custom rom, apparently it helps or something? not fact but ive seen a few people solve it with this issue
What kind of roms and kernels are you guys using? And what governor?
Cheers guys, Jack
I've seen most people running Franco kernel with either cyanogen mod 10.1, PAC or paranoid android. You'll probably get a similar battery life with all of them, and probably the best your going to get.
Check your wake locks, use juice defender, check you're not dropping in and out of signal (hammers battery), turn of location settings...
Sent from my GT-N7000 using xda premium
AKOP or CM with franco give me hours (4+) of calling or 1.5 days of moderate use.
I also have notification widgets on so I can quickly switch BT/WIFI/Brightness AND I make use of nfc tags so when I'm home wifi is auto turned on and when in the car it turns off.
From my experience, these battery saving apps such as juice defender are not good, you shouldn't use them.
About the battery life, there are tons of recommendations... stop syncing, turn brightness to as low as possible, turn off 3G when you don't need it...
Dont use your phone..
Seriously now, the battery is not bad at all, and in battery usage cases you need to state your usage of the phone (games, mail, 3g on most of the time? widgets? surfing and screen on time)
Without those parameters none can determine if you have wakelocks problem / some app is draining your battery or eventually maybe it's only psychological problem
Take in mind even on auto brightness, if you are playing heavy games dont expect to last a day or so..
Tricepz is on the money!
Need to analyze Your usage!
Most importantly you need to understand that this is not a primary game console or music player.
Things that drain battery fast!
1) Live Wallpaper
2) Games
3) Phone calls
4) Equalizers
5) Apps
Best to monitor your usage!
Personally I use the phone as follows for 16 to 22 hrs of usage.
Bus
1) 4 hrs of music with quality headphones that have noise canceling tech. Abel Planet 200b with built in amplifier.
2) 3 phone calls a day!
3) No games ! Have a tablet for that
4) Minimal reader for new feeds only updates once a day.
5) Music app either Apollo or NexMusic great music players without equalizer. simple controls.
On an average day headed to work paying bills I see 10 to 12 hrs easy.
Busy day on my phone 8 to 10 hrs.
Turn off services you don't need or use.
WIFI - Turn it off when you leave your house and when you don't need it. Leaving it on will drain power as it will continue to scan for a connection.
GPS - Turn off your GPS if you don't need.
Sync - Sync when you need to. Turn it off and access it manually.
Bluetooth - Turn it off when you don't need it
Location services - Go to the Settings menu and head over to Location access and switch "Access to my location" to off.
Backup services - Head over "Backup & Reset" and uncheck "Back up my data".
Screen brightness - The lower the brightness, the more power you'll save.
Apps - Applications like facebook and Google Maps will remain online as it runs in the background. As a result it will drain your battery. It can prevent your phone from entering deep-sleep to preserve power.
Signal - Connection is very important. If you're in a area where service is low to poor, your phone will draw more power to stay connected to the nearest cell antenna/tower. It's best to turn off on connections if you're in a no service area. Simply put the phone in "Airplane mode".
Usage - Battery life is dependent to whatever tasks you are performing on your phone. If you play games daily for a long period of time, then you should expect the battery to decrease dramatically. Conversely, if you just email, text, browse the web, make calls, little to no games then your battery life of the phone should last for quite a long time.
Useful apps
Greenify - This application allows you to hibernate apps from starting up like facebook, Google Maps and many more annoying apps that run in the background when they shouldn't be running. https://play.google.com/store/apps/...GwsMSwxLDMsImNvbS5vYXNpc2ZlbmcuZ3JlZW5pZnkiXQ..
Wakelock Detector - This wonderful app identifies apps that running during your usage and sees which one has been running the longest without your consent. You can use this with Greenify. https://play.google.com/store/apps/...EsImNvbS51enVtYXBwcy53YWtlbG9ja2RldGVjdG9yIl0.
BetteryBatteryStats - Similar to wakelock detector but offers a more in-depth look of wakelocks that active during your usage. https://play.google.com/store/apps/...wiY29tLmFza3N2ZW4uYmV0dGVyYmF0dGVyeXN0YXRzIl0.
Kernels and roms
One major reason why root is amazing. Kernels offer tweaks that are beneficial for the phone to perform smoother and offer amazing battery life. Offers more tweaks as well like gamma and undervolting. Roms can contribute a small portion of battery saving but not much.
Did I miss anything else?
Adding Maps to Greenify usually helps a lot regarding battery life, can leave GPS on for other apps when doing this and won't suck any battery.
try franco or faux and then UV and UO ` its works for me, 4+ screen time easily :fingers-crossed:
I didnt expect so many comments! ive used franko kernel and air kernel before and no change
ill try some of them apps that everyone has mentioned
again thanks guys! Jack
Just use a ROM for a while, let the battery do some cycles, and use the phone for that, as a phone, remember that we have a Quad Core here, i'm on stock rooted only, and last night i get 12h20m37s with 4h48m SOT with about 7% left, so that's pretty good. And i really use my phone, Twitter, Flipboard, G+, Wifi on all the way, Sync on.

With 80% left I have 1hr of screen on and 10mins of call time, this is with whatever kernel the latest CM nightly is using, so yeah you could definitely get better but I have to think facebook is the contributor since I too have twitter (plume) and tumblr without the same battery drain.
greenify is a must to disable rude apps which do thing without asking, like facebook, games, etc, they connect to internet to download ads and sttuff, facebook being the worse cpu eater
i use 2g only, wify in home, disable wifi outside,
only wassap active, some opera mini browsing, pics, talk, sms, little gaming, i get 1.5 days
off course heavy gaming kills the battery, because of 3d, even 2d games drain the battery because of the screen, like angry birds
using stock 422 + franco
I like to use JuiceDefender only when the phone's battery gets really low and I want to sacrifice some functionality. It works well, but only if you allow it to keep 3G/Wifi off when the screen is off.
I use facebook so much though, ugh :/ ill give it a go and if the battery lasts longer then ill get rid of it
single biggest difference I've seen is to stay on wifi all the time as much as possible. I leave it on no matter what. Granted if you are out and about, it won't help but once you get to home/work/friends/etc, your phone will immediately connect and start saving you juice.
91% after 8 hours with light usage at work. With 3G, I normally would be approaching 60-70% by now with light usage. That 3G drain is real and should be avoided whenever possible.
Don't play games. It seems like no matter what game I play, it'll almost always lock my cpu to the max frequency until I exit. Even really simple non graphics intense games.
Well ideally you're biggest battery drainer should be the the display. If it's not then read below.
1) So for the screen the best way to go is to get a stable custom rom like xenon and tinker with the auto brightness settings. Tweak out auto brightness settings to your liking (they're generally very overbright by default) and you'll see major increases in data.
2) Screen aside your other biggest drainer is cell radio. Particularly if you're in a low signal area it will drain your battery really fast. So if your using wifi anyway be sure to turn data off and switch to 2g. That way you'll have a strong signal and 2g drains less battery anyway.
3) As some people have mentioned already. rogue apps. Social networking apps are a huge drainer in this regard. Especially facebook. You just can't have that app on your phone and get decent battery. As for other apps which draw on unnecessary background data, Greenify their a**es.
I got a S4 i9505 with albe95 S6 port ROM. I've tweaked the settings to pretty much disable all background activity so there's no syncing, no GPS, no bluetooth no NFC etc. I've got airplane mode on 24/7 with WiFi turned on. I've also installed Greenify and System Tuner Pro (I have root) and disabled a few GooglePlayServices services and stuff. Followed a tutorial for that. Looking at the settings app, I've got 40% battery remaining and have been on battery for 2 hours 40 minutes. Probably slept for 30-45 minutes and when it was on, I go on chrome, mess with Theme engine and some other light stuff. Now I just waited 20-30 minutes and it drained 4% screen off. I waited 5 minutes and it drained 1%. Is there an app that runs in the background and I leave my phone screen off overnight to tell me what processes are using the most battery and then disable those processes? I've tried to google it but none have helped. I've disabled Gtalk and a bunch of other processes, no luck. About to download Titanium and mess around with Greenify a bit more. I'm new to Android, reason I don't like Android is it's battery life. My iPod touch 5's 910mAh battery lasts 5 hours watching YouTube, surfing the web and light gaming (Clash of Clans) while the S4's 2600 mAh battery lasts 3-4 hours. Triple the size but less battery life?
Android's root is a lot more complicated than iOS, we just go to Cydia and download tweaks like an app from the Play Store. But yeah, any apps you guys use to check background processes using battery?
It's called BetterBatteryStats.
I don't think you will find it on the play store. Or if it's free there. There is a free version on the forums here. And I mean free, not cracked or anything.
And there's more to battery life than just mAh. Your iPod has a smaller screen and a smaller resolution. Which means less work for the GPU.

Right so I messed around with BBS and I discovered the different tabs. Looked at Kernel wakelocks and Partial wakelocks. Did some research and PowerManagementService is a big one. Was told to go to partial wakelock and found RILS and RILJ0. Did some more research on that and it's related to radio and wireless stuff. (Radio Interface Layer) Did some MORE research and apparently my modem is the problem. Someone suggested me to get "GetRIL" from Play Store and see if the two ... things match but GetRIL either isn't compatible or it doesn't work. Now problem is, I have Airplane mode on 24/7 and WiFi enabled so cellular should b turned off, right?
With airplane mode on yes, network should be turned off.
The modem can be changed anyway. So maybe you just have to update the modem.
Also try a different rom.

I read that ROMS and kernels have no affect on battery life other than disabling sync and background stuff in the settings app. Only time it will affect battery life is if it's badly written.
So if cellular is turned off, why is "Cell Standby" the second most draining thing behind "Screen"? All the websites I looked at just say "Turn airplane on and wifi on" but what I'm really looking for is to completely disable cellular with "System Tuner", or do something with root permissions to force stop cellular. I've got no SIM card installed.
Not true. Both kernel and ROM can have a significant effect on battery life. For the kernel, a custom kernel can improve battery life by allowing the processor to be undervolted, thus using less power per CPU cycle. The ROM could also have battery-saving features, e.g. Doze in Android 6.0. The ROM could also have battery-sapping bugs.
The modem is separate from the ROM and kernel. It will have its own enhancements and is updated frequently, so you should update it.
If you dial *#*#4636#*#* you should get to a menu where you have the option to turn off radio. But that's probably the same thing as airplane mode.
And roms and kernels do have an impact on battery life. I once flashed a kernel that drained my battery very quickly. The same rom without that kernel was fine and with great battery life.
So, as I said, consider changing your rom. Just to see if it is rom related or not.

I updated my modem and bootloader from the same thread as my ROM, not sure if it did anything but I've managed to raise battery life from ~4 hours to ~7 hours just non-stop google chrome, theme-ing, downloading apps and trying to get better battery life. Also watched some YouTube videos.
I actually flashed this ROM because of themes, specifically the Avengers theme. Also there's a few pure black themes, did some research and pure black actually gives your battery ~40% more juice. Real world usage will probably be at least 15-20% more battery. But I'm still trying to find out how to fully disable cellular, anybody know? I've got root and Titanium Backup. I'm not sure what to freeze though and "Cell standby" continues to be the second most draining thing in the settings app.

Dialing that says "Not registered with network" because I have no SIM installed. Cellular would kill my battery but even without a SIM, cellular still is active because of emergency.
I've googled everything I can think of, within 2 days I've increased my battery by at least 60% but cellular is driving me nuts. It's using ~20 of my battery while using my phone, that's 20% plus another ~20% once I find a way to get a pure black theme that works in third-party apps as well for my AMOLED display. Also, titanium backup isn't able to convert Google Play Services or GSF into a app so I can greenify it. It just processes and processes.
There is no theme that can make all apps black. Dark material makes many apps pitch black, but it's for CM based roms only.
You can get the pro version of greenify and maybe xposed. Then you can greenify system apps. Including Google play stuff. But greenify works only when screen is off. When screen is on, the greenified apps will run again.
Or use titanium backup to freeze everything Google play related, until you need it. But doing so will require you to input your gmail account again.
You might also freeze the phone app and anything else related to network. Since you're not going to use the phone for calls. Maybe that will solve cell issue.
Right, I have no idea how I did it but my phone for the past hour and a half has not dropped a single percent and has mostly been in deep sleep. No more wakelocks too, only thing I noticed was a alarm from Google in BBS but didn't mind that too much. Excited to see how much it will drop overnight.
Also, do you know the largest battery for the S4 that I can buy on amazon.ca? I don't want a case or a separate battery, I just want a battery that's more than 2600 mAh. So far, I think the ZeroLemon 3000 mAh battery is the biggest but I heard it's got no NFC. I don't use NFC or anything wireless other than WiFi but could you give me a quick explanation of what this does cause apparently it's a part of the battery itself.
You know that thing where you put two phones together (back to back) and it transfers data from one phone to the other? That is NFC. You can basically send web pages, app pages in the google play store and phone numbers with it. Just bring whatever you want to send on the screen and touch your phone on another phone to send it.
You can't sent actual apps and files.
The connection is established through connectors on the battery. That's why it won't work if the battery doesn't have one. It also is a method to verify the autenticity of batteries. Fake batteries don't usually have working NFC.
Now, the biggest S4 battery I heard of is about 9000 mAh. The second is 7500 mAh. I don't know if you can find them on Amazon.ca.
Use amplify and limit all "safe to limit" wakelocks.
