I am not responsible for any damage to your phone and/or any consequences from your phone being bricked, exploding in your face etc etc etc... You are expected to read the full description and use your brains to process this information, before even touching your phone. Assumed is that you know how to flash using CWM.
Whining that you disagree to remove bloat is not appreciated; If you want to keep your phone bloated for whatever reason, you are at the wrong thread. Feedback should be substantiated and reproducible, not a ventilation of your bottom.
Context
The intention of this thread is to set an approach how to minimize the battery consumption when you are NOT using your device, e.g. when you are at work, sleeping, at some place that does not allow you to recharge, etc. This guide explains how to thoroughly remove stuff that you probably do not need, something that certainly will not affect your battery life in a negative way. The approach is based on the ROMCleaner script, which was extended a bit. Whether it is necessary to remove all the stuff as described, is debatable - nevertheless it is an approach that works for me, otherwise I would not be posting it.
Because a lot of people replied with phrases like "this is bullsh*t", let me state the following: This approach is in no way a guarantee that you will actually achieve battery life longer than 2 seconds after a full recharge. Neither is it a part of the bible, it is merely the approach I followed to prolong the battery life of my device - which I like to share with you. If you are still hating, wonder yourself: "What have I contributed lately?". In any case, at least try it out yourself before drawing your conclusion beforehand and polluting this thread.
The second discussion point is whether the battery should last longer than 1 day. According to many, you are not using your device properly if you would like this to be the case. My answer is simple: If you have no such desire, move along. If you do, like I do, this topic might be of some worth to you.
Furthermore, I honestly do not understand statements like '2-3-4-5 days is impossible' on one battery charge. If you are convinced that Jesus will return again, please do so, but give other people the space to actually find out whether it is the case for themselves.
Some Introduction...
Have you been annoying your ass of because your battery is drained within a day, without even using the phone while at work? I certainly have. Coming from a SGS1, which used to serve me at least 3 days on one charge, I got instant diarrhea from the battery life of the stock SGS3 firmware.
Then I downloaded a ROM, stripped everything unneeded and more and finally got a battery life of approx 3 - 4 days. However, because I had ripped a ROM apart, which was a manual operation, updating became quite time-intensive. Therefore I also did not update, until the recent JB leaks. So this time I though: Lets make a script to do it for me, in order to make updates possible in an easy way. Then I only have to run the clean-script after an update.
After some testing, I am finally satisfied with my device again - Check out the screenshots. The results are achieved while having wifi constantly on, using google sync and whatsapp. The screenshots are based on Wanamlite XXDLI7; The first shows the battery usage during a night, the second during a day of light phone usage. I will post another screenshot when the battery is drained completely.
What to expect and trade-offs
After completing this procedure you can expect significant increase of battery life when the phone is idle. If you are using the phone actively all day long, then this approach might not be of much worth to you. People who do not have time to play with the phone all day, e.g. because they work during the day, will probably find this most useful. The cleaning of your rom will remove about 70% of the apps/widgets that come by default, therefore it is wise to check whether you will not lose apps/widgets that are valuable to you. You are still free to modify the "script" according to your need/desire.
So what do we need?
A DEODEXED Stock-based ROM, I prefer wanamlite http://forum.xda-developers.com/showthread.php?t=1705866
ROMCleaner - http://forum.xda-developers.com/showthread.php?t=1827817
The attached ROMCleaner_user.txt will sustain default samsung browser, calendar, email and messaging. (untested)
The attached ROMCleaner_user_jb-apps.txt expects you to replace the JellyBean apps discussed next. Beware that the stock browser, calendar and email are not tested by me and could drain your battery faster.
Because I had some issues that ROMCleaner would not read the ROMCleaner_user.txt, I had to integrate the file into the ROMCleaner package. To do this, you can download the ROMCleaner package and replace META-INF\com\google\android\romcleaner\ROMCleaner.txt in the zip by the file you just downloaded.
Packages to restore some stuff ^^
If you have chosen for the JellyBean apps package (jbapps-avdaga.zip) you will get:
JellyBean browser + calendar ripped from http://forum.xda-developers.com/showthread.php?t=1797109
Inverted JellyBean apps: email and messaging ripped from http://forum.xda-developers.com/showthread.php?t=1780559
In case you want Samsung Apps store for free fancy games, get it from http://forum.xda-developers.com/showthread.php?t=1861409
Got the packages, whats next?
Put all files on your phone, reboot to CWM.
Make a backup of your current system, smart monkey.
Flash the JellyBean ROM of your prefrence if you have not already. (If you come from ICS, wiping your data guarantees best results).
"Flash" the ROMCleaner script, either by using ROMCleaner_user.txt approach, or integrating the file.
If necessary, flash the provided JellyBeans apps package and Samsung Apps package.
Reboot and enjoy your awesome battery.
Thanks to
Wanam for his awesome ROM.

@OP: Your post is missleading. Removed bloatware has nothing to do with the battery life.
After intensive research I came to the conclusion that there are only 2 major issues for the battery drain on vanilla stock ROM (JB DLI8).
Those are:
1) Samsung push service : SOLUTION -> simply unstall it, bacause you don't need it anyway (e.g. via Titanium backup).
2) Wrong fast dormancy setting : SOLUTION -> use https://play.google.com/store/apps/details?id=com.gokhanmoral.fastdormancytoggle.i9300&hl=sl from gokhanmoral to toggle it to the setting supported by your carier. BE careful not to toggly it exactly the oposite.
With these 2 mods on stock DLI8 I get less than 0.5% battery drain while idle over an hour.(Mail sync set to every 30 mins)

I've been on Stock-rooted since I got the device. I'm definitely going to try this out.
I use my phone plenty, doubt I'd be able to get 5 days out of it, but we'll see.
Is it better than just freezing all the unwanted apps?

It should, make a backup and try for yourself. Do take into consideration that you might need the default ICS apps or simply use the ROMCleaner_user.txt, not the JB one.

The first image is supposed to show how it performs when idle, the second is after a day of usage. Primarily used it for some messaging and calls though, however the main point is that the battery is not drained when not using the phone. When I used a stock rom the battery was depleted for 50% after half a day without me even touching the device :-\
Of course if you use the phone normally the battery will be depleted in 3-4 days, like i mentioned in the intro.
I know how to get years of battery life, charge your phone to 100%, take the battery out for at least 2 years, and it should have some life left in it, you must make sure you don't put the battery in for at least 2 years.
What are you guys whining about..if it can improve your battery life and remove the apps that you dont need, why not? You should be thankfull that people put their work in such things in their free time.

Yay, let's remove a bunch of features from the phone so that when you're not using it at all, you can get 5 days of battery life! :silly: Your claim of "normal" usage equaling 3-4 days is pretty unrealistic. Battery usage is subjective with thousands of variables, which makes lofty claims of battery life completely pointless.
Nearly all of your battery life improvements are just doing step #1.
You're using a rooted and tweaked stock ROM with a tweaked kernel. Just by doing this, you're going to get much better battery life versus stock ROM. Nothing new to see here. Removing what little other "bloat" that Wanam left in the ROM by removing a bunch of apk's (that don't run anyway unless you launch them) and replacing a few ICS apps with JB versions will only offer a very small improvement.

Please install any stock-based ROM and check the services that are running in the background - without you even know you had them. There is a lot of garbage coming in all stock-based roms, and I really do not understand the problem of removing stuff you do not use; Morever, I think this is something people should do in all apsects of life; that is removing sh*t you do not use.
I conclude your assertions are based on thin air, as you did not even take the time to test this approach. I have spent quite some time testing stuff out and posting my observations here - so please do not post if you have nothing constructive or reproducible to say.
Last thing: I do not replace ICS apps with JB, this stuff was tested on a JB rom - but you knew already because you read the full post
so basically you debloat a stock deodexed Rom? Any other changes I'm missing?

Besides changing some samsung apps for CM10 ones, that is it indeed. Though the debloating is more thorough than proposed by others.
Ok, thanks,, just wanted to know exactly what the script did, prefer my own debloating and tweaking, but good for newcomers.
there are also people that are not normal and want to use their phones on trips or in situations when they have no charging opportunities

My thoughts...really.
I don't wanna sound rude, yet i had to agree with some when they say "buy a Nokia (old one of course" or just "disconnet for one or two years".
It's virtually impossible with the kind of gadgets we have these days any battery last more than 1 day.
I've made my own mods and roms from scratch in recent past for X10, so u may consider at least that i known what i'm talking about.
The only way, no mather witch brand you like or believe its the best, is by f#@king your screen. Period. That is the main reason why every phone just last 1 day with "normal" use.
If you've payed attention i've used "normal" expression witch means phone, mail, sync and didn't wrote "heavy use" that will include music, YouTube, videos, etc.
Like i said. I've made my own work in the past and still do some minor (?) changes and i must say this: i'm glad if my phone last one working day from 7AM till 23PM. Yes! Working day, that's why i dont't develop anything.
If you or anyone else state that your/his phone had better battery life than this i make two considerations:
1. You're (not you in particular) a liar, or;
2. You simply don't use your phone as you can.
If you dont consider that you belong at the first consideration than..."buy a Nokia..."
Another thought:
You just bought this (or similar) phone for a status matter or money it's something that's really cheap for you (another 2nd choice).
Like i said...just my 2 cents.

I've had an AT&T Note 3 since January. The phone is great but since the update to 4.4.2 I have been experience horrendous battery life, to the point that I'm having to charge it throughout the day.
I work construction and use my phone for several hours per day, resulting in 2-3 hours of voice calls and 2-3 hours of screen time. My last Note 2 and the current Note 3 used to be able to handle my workload while being unplugged from 7AM to 10PM at night.
If I was to root my phone, could I gain back my battery life? I have never had the need for my phone to be anything other than stock but I am desperate at this point.
Thanks
Rooting your phone will not result in having better battery life. What you can do is detect apps that keep your phone awake. Another method is to flash a custom kernel with lower voltage or one on which you can undervolt yourself. Be aware that by rooting and/or flashing custom recoverys/kernels or firmwares you'll trigger the Knox counter. This will void your warranty. There is no way to revert it.
Please use the Q&A section next time you have a question. Hope I could help you a little.

I appreciate the reply. I was hoping that rooting would allow the phone to run off of custom firmware and not have the horrible battery drain many Note 3 users are experiencing after the 4.4.2 update.
I have installed GSam Battery Monitor for over a month and been monitoring it daily. I'm consistently seeing Android System and Kernel (Android OS) using 40% of my daily battery life and Media using another 15%-25%. Other than that I've been unable to determine much else. I do not play games or Facebook, I just talk and text all day.
Is the warranty on the phone one year? If so, I'm 2/3 through it and would be willing to void it for better battery life.
I have looked through all I could find before posting, but honestly am somewhat overwhelmed by all the information on XDA. This is magnified by the fact that there are many versions of the Note 3 and different carriers.
I have a N900A Note 3 and am looking to get my all day battery life back and appreciate the help.

Don't worry, it's normal to suffer infoglut the first time looking through xda. You'll get used to it =)
So you have the AT&T version of the Note III aka hlteatt or SM-N900A. You're device has a Qualcomm chip built in like most of the Note III variants out there. There's also a Note III variant which has an Exynos chip built in but I think you won't confuse Exynos firmwares with those dedicated for Qualcomm variants. The ROM threads ususally have pretty good descriptions about that. AFAIK most custom ROMs are compatible with any Qualcomm variant. E.G. any AOSP/CM ROM for the Qualcomm Note III has a unified build carried by the name "hlte". Meaning, that as long as you don't flash an image meant for the Exynos variant, you should be good.
40% for Android-System and Kernel isn't normal at all. I also use GSam Battery Monitor. Android-System and Kernel only use about 19% of the battery on my phone. Something that helped me when I had the exact same issue was to switch locating method from high accuracy to power saving. You can find this setting by long-pressing the GPS icon in the notification drawer. The location settings menue will pop up. Under "Mode" you can change to "Power saving". I'd be happy if you could report if it did work for you.
You're welcome =) Just hit the thanks button.
If I may add my own comments here:
1. you should go to note 3 ATT forum and there find proper method to root your phone, we have towelroot program that can root phone very easily without breaking knox warranty, albeit I don't know if it works on your version, it worked perfectly on mine (t-mo)
2. While it is true that root by itself won't do anything about your battery usage, many programs that really help need root
For example greenify, titanium backup or android assistant require root to disable many useless (useless for you that is) programs that drain your battery
3. I totally disagree with Nitrous that GPS is the culprit for high battery usage. It is my experience that GPS all by itself does not work at all unless the location info is requested by some other programs. Google maps for example only run GPS when screen is on, when screen is off, GPS is off also. However some badly behaving programs can keep requesting location even in the middle of night, but IMO those programs are the problem, not GPS itself. I have GPS, BT and WiFi on 24/7 and with light use my phone could last 4-5 days. If GPS was draining battery as many people think, phone would never last that long.
What you should do is go to ATT forum and find towelroot method, root your phone and freeze, or disable apps you don't use. For example I don't use Bloomberg, Yahoo, Facebook, Hangouts, indexing etc (your list may be different, since different provider) so I have them frozen (won't start up) . If I ever change my mind, I can unfreeze them later.
You can also run programs to tell you which apps use most battery, or wake the phone from sleep and then decide if you need them or not.
BTW sometimes full reset and cache clear can fix some of the problems, so maybe that should be the first step.
Once you find which program /s cause problems your phone should last whole day. I could easily get 6 or more screen hours on my Note3, unless playing some intensive games, so should you and it just took couple hours to identify and disable all the bloat and there is a lot.
I also experienced increase in battery usage after updating to KK, but I have not found a time to look over the bloat and redo my program freezing efforts yet.
I know that GPS doesn't drain battery that much. But trust me, it is very likely to cause that type of behavior. I'm in this forums since a couple of years. In most cases, when Android-system and Kernel drain unusual amounts of battery it was location services that was causing it. But not because they were using GPS, but because they kept the device awake the whole time. And there you see my point of switching locating methods. In 90% of the scenarios where people described this kind of behavior of their devices, this solved the problem. But you're right in saying that it's not a permanent solution. I agree to your first two points.

Just to give quick update, after I wrote my comments here, I fully charged my phone and went to sleep. In the morning battery was down to 80% and that finally prompted me to action. I freezed some apps, cleared cache and did some "housekeeping". I don't know what did the trick, but this time overnight my phone went from 100 to 98%, 10 times better than a night before. Now, after 18 hours of some light use like few calls, couple games, light internet use etc it is still at 80%, so it's pretty much back to what I had before update. I wish I wrote down what I did to track particular culprit in my case, but it is amazing how couple bad apps can ruin battery life, but at the same time killing them turns things around so much. All in all, out of some 340 apps and services on my phone, only 21 are frozen and about 30 are stopped from starting at boot up, but are able to start later if needed.

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.
I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol
My battery is from October 2015. It's the original one that came with the phone
Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?
Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).
Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle
I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind :..

Ive just unplugged it 50 minutes ago and I have 10 percent left with only 10 minutes screen off... There is something wrong and I don't think the two batteries (old and new) are in bad state in the same way... There may be something else..
Have you tried to install the stock firmware through odin? PS: Read the instruction before trying it!!!

Make nandroid backup with TWRP and flash official firmware. That's just not normal for any kind of battery (good or bad)

Right now I have DreamUX V2 A7 (2017). I flashed one week ago hoping to remove this strange battery behavior. But it remains. Do you think reflashing stock firmware will fix it? I'll check instructions before going ahead. Thanks to both!

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic
Thanks
Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help
Hi everybody,
I've have my Axon 7 for almost a year now. Been using it quite intensively, mostly for gaming, taking advantage of the fast charging and going through 2, sometimes 3 battery cycles per day.
For some time how, I've began noticing my phone running slower than before and that it generated more heat doing the usual tasks. I don't know if the slowness stems from the heat or the heat comes from wear and tear on the phone. Anways, I was looking for things I can do to make it run smoother.
- Will be to looking to switch to Lineage OS, perhaps I'll have a bump in smoothness. Do you think that will help?
- Can dust accumulate in the device and make heat exchange less efficient? Should I open it and shoot some compressed air at the motherboard or something?
- Does the heat come from old, overused battery? Will swapping the battery for a new OEM one help?
Thanks in advance!
Wipe the cache or do a factory reset
Check how much storage u got left.
And right, a factory reset or and wiping cashes could help too
Edit: for fast and buttery rom give dark rom a chance.
HELP!!!
I picked up an H918 for my wife to use on T-mobile USA. Since it was used, I also got one of the extended life 4100Mah batteries to hopefully make it last at least the entire day without topping off the charge. She usually averages around 4 - 5 hour SOT, so this seemed like a good option from what I've read, and fits in the original door so I can use the wallet case she wants with it.
But man, her battery life is TERRIBLE! I checked with Accubattery, and it reports that the battery is charging within 99% of it's 4100mah spec, so I don't think its a bad battery. Yet, she can barely go 12 hours with just under 2 hours SOT before the phone dies!
She is unrooted, running stock Oreo.
I installed GSam Battery Monitor and used their ADB commands to give it permission to record deep statistics w/out root (pretty cool, never did that before). I ran it for a little while this morning. Within 3 hours 40 minutes off the charger, she was already down to 72% with barely any SOT. I'm attaching screenshots of the app usage and doze screen (sorry for the phone-snapped-of-phone picture, it's my wifes phone like I said, so it was easier to just snap with my camera than take a screenshot and send it to myself to post).
Maybe I'm not reading this right, but it seems like something is keeping her phone from sleeping. A big culprit seems to be call services, and in my location settings, I noticed it mention that LG IMS was doing a lot of heavy battery drain with location related inquiries.
I thought maybe it was related to WiFi calling, so I turned that off. Cell reception is average.
2 hours later, she's down to 50% so that wasn't it. I don't know what else to try other than hard reset, but we literally just got this and set it up 2 days ago, and its been like this from day one. I don't see why it would be any different the second time around.
It's likely a junk battery. It's really hard to get a good oem replacement battery.
If you shop Amazon look for a Taeozi 4200 or Shemnz 4200. They both have 2 year warranty and decent reviews here on XDA
The Perfine 4100 is also highly recommend
Any Li-polymer should be better

When I bought my wife's phone it had a battery drain/overheat and wakelock issue as well. I fixed it and haven't had an issue since. Here's what I did to fix it:

I did my homework first and got the Perfine from Amazon, not a no-name junk battery. When I couldn't fit it without removing the sticker, the seller was really helpful and actually offered to replace it after checking first that it fit in *THEIR* V20 at the factory. Really solid customer support. And according to Accubattery, it really is the capacity it says. Or at least within 99% of it (I think it estimated 4080 or something like that). So I don't think that's the issue.

That's actually really interesting- I did take apart the phone to do the thermal mod thing (wiped off the dried up pink gunk and put a thermal pad there), but it seemed pretty clean otherwise inside when I did. How on earth did you figure out that was the problem?
After speaking with some folks on Telegram, Reddit, and other corners of the internet, I have a different theory. A bunch of people told me to let the rom "settle", that battery life is never good after a fresh format or new rom flash. Honestly, the critical thinker in me says that sounds like nonsense. I've never heard of this before and I've been flashing roms for the better half of a decade. I'd think after it takes the time the load up your apps and settings and configure itself, it would be done. But I Googled it, and it seems to be a hotly debated subject.
Those that swear by it claim that whenever you start fresh or flash a new rom, it takes anywhere from one to a few battery cycles before the kernel calms down. Perhaps it is doing some sort of internal calibration based on your battery life and system demands or something like that. The theory seems to be that the Kernel doesn't allow the CPU to fully doze until it is done with this process, which sometimes takes days. I don't know, but the more I read about it, the more it sort of started sound plausible. When I got the phone, I tried out some things on it myself without a SIM card first, just to make sure everything on it checked out before giving it to the wife. Then, I did a hard reset, popped in her SIM card and let it do its thing. That's when we realized battery life was pretty terrible, as after 10-12 hours she already needed to charge... and this was on the 4100mah perfine!
I tried another hard reset, and when that didn't fix it, I decided it was time to root and see if I could get to the bottom of the bad battery. It seemed the kernel was where a lot of it currently went according to battery stat apps. After downgrading my H918 to Nougat so I could install TWRP, I promptly flashed Alpha Omega Oreo 20H and restored her apps. Turns out the next morning we couldn't sync her smartwatch, somehow we broke bluetooth (going into BT settings would crash the phone everytime). So weird, and while we were at it the battery life still wasn't great. So I did a hard reset that evening and found that even with nothing installed, BT was borked. (looking back at it, I think I should have flashed an Oreo rom like the stock 20H rooted first, and THEN the AO rom. I think going straight from nougat might have led to a driver mismatch or something)
Anyway, after that didn't work I flashed the stock rooted 20H rom, and lo and behold bluetooth and everything else is working again! But the battery has been bad all along and is still doing its generally suckiness thing.
BUT... as someone pointed out, if this kernel settle thing is real, I've been pretty much flashing and resetting this thing every other day. If roms need to "settle" first (still a debatable subject), than I never really gave it a chance yet and that's why I'm constantly seeing battery drain from things like Kernel even on different roms! And @pistacios, is it possible that you were having a kernel do the same thing since it was just reset and it just so happened to be that when it calibrated itself you thought you had fixed it by cleaning out the USB port?
All I know is I'm going to give this a couple of days before deciding on a plan B. Seems too simple to be the reason, but hey- I'm desperate.

Ive experienced ROMs settling in and battery stabilizing after a few days. But this was pretty far back with the HTC M7 and M8. Most modern phone's I've flashed pretty well settled in within the first few hours. The battery life on this phone was never amazing. It was good to just Ok for most when it was new.
If you flashed the stock rooted rom and still had bad battery life, I still suspect the battery itself. I still recommend one of the battery I listed earlier. If the perfine didn't work out try a different one.

Right, with the stock 3200mah battery. With the Perfine 4100, a lot of reports are saying 6-7 hours SOT or at least a full day of regular use. That's good enough, really. Mine is dying at half of that. I'm wondering if I have faulty hardware. I could put the stock battery back in and see if it dies much sooner.
I'm actually wondering if someone can check their mA use per hour with the screen on vs off, and I can see if the numbers make sense on mine. Accubattery is pretty good at the math.

Phone was up and running for 2 weeks, so it wasn't due to fresh reset.
GSAM battery monitor showed kennel wakelock, something about USB OTG in the top of the list, so I figured the port was my first check for a problem, and it was. It wasn't obvious that there was dirt or foreign matter in there, because it looked clean. But sure enough, after the light brushing with 94% alcohol, the problem disappeared.
I'm not saying this is definitely your problem, just throwing it out there.
