Snce I have updated my GS2 to ICS my battery drains insanely fast. I don't even do anything with it. I go to the battery consumption table and it seems like the screen is overusing the battery. The rest are fairly normal percentage.
Like I mentioned in the beginning I only have this problem when i'm using ICS. Right now I have the stock ROM that I downloaded from SamMobile. When I'm using custom ROMs it gets worse. What could this be?
And yes I did try to search for similar problems, because it seems like a lot of people have problem with the battery but no one had the exact same problem as me.
I can just add that since I last charged my phone my screen has been on the lowest brightness and the phone had just been lying on my desk. I haven't even touched it. still 7% has been drained and the screen seems to do the job.
Does anybody know how to fix this?
Same to me....Plzzz guys...Help US.
Battery drain is the hotest topic on ICS these days. I believe the high RAM consumption of ICS is causing battery drain. Almost every ICS rom is having this issue. You are not alone. Relax and wait, you will see improvements.
-
In the mean while, you can install "betterbatterystats" to find out what is draining your battery. Good luck.

Percentage means nothing. What is your screen on time? (Click on display to show these details)

Well now the screen has been on for one hour it says and my battery is on 77%. This is messed up...

So when you clicked on display, it showed that screen on time is 1 hour, and your battery is currently at 77%? That isn't terrible, actually. That means you're on track for a little over 4 hours of screen on time before your battery will reach 0%. Average screen on time for full battery discharge is usually around 4-5 hours.
If you are using the phone, and the screen is on, the battery WILL drain.

No believe me this is not good battery time at all. I have screen on lowest brightness and barely use it. Even when it's just lying there with screen off it drains a lot. I mean I have had this phone since last summer so I have had it or a while and he battery was pretty good before. But since I updated to ICS the battery drains a lot faster than before.

You just said the screen said it was on for an hour, and the battery was at 77% in your post above. So was that not accurate?
If it is draining more since you upgraded to ICS, and you want it to get better, then you have three choices:
1 - Install BetterBatteryStats and other monitoring apps to figure out what is keeping wakelocks and other processes running on your phone that is draining battery...
2 - Do a factory reset/full wipe and see if it was an errant app you installed that could be draining the battery, then slowly start adding your apps back one by one... or
3 - Flash back to a Gingerbread firmware.

Yeah I guess you're right, but at the same time the battery is very very bad compared to before so I'm confused. Maybe I was just enjoying a really good battery time back on Gingerbread?
1. First of all that BetterBatteryStats is too complicated for me. I tried to use it before I didn't get it. What am I supposed to do when I find something that is draining my battery. Should I freeze it? Uninstall it?
2. I have tried this a lot of times, no change.
3. If I use Gingerbread for some reason the APN settings with at&t doesn't work properly. I lose connection very often. So I'll rather have worse battery time for now. Is there a solution to the internet connection?
Thanks man I appreciate you taking your time!

A factory reset? Then maybe a clean re-flash of the newest ICS could be worth a try then.

What modem/baseband are you using with Gingerbread, that could make a difference with mobile data dropping.
Also, what APN settings for AT&T are you using? There are a few different APNs. The two major ones are "wap.cingular", and "phone". The one you should actually use will depend on what kind of data plan you are signed up on.

When I'm on GB I use KL1. Is that what you're asking? I had no idea there were two different APNs... I use "wap.cingular"
Do you have the APNs for "phone?" It would be awesome to have that. Then I could just go back to GB until they fix it.
BTW I checked my battery stats again, 24% left. It says screen 56% and Time on: 1h 54min... So it's is pretty bad, right? . It dropped really fast.
Android OS is second with 15%.

APN for "phone" doesn't work unless you have a specific data plan - namely any 4G plan. So if I recall from some of your past posts, (I remember you now) you're on the non-smartphone data plan, right? Then the "phone" APN won't work for you if you are.

So you're running a clean flash? No downloaded apps installed yet? Yeah, that's terrible. Sorry to hear. I would go back to Gingerbread.
Reading stories like yours makes me glad I'm still ON Gingerbread.
The problem is that I'm not really using the screen that much. today I have just listened to music, not even used the screen that much. Just text a little bit an nothing else.
But still it shows up as if I have used the screen more then the other apps running in the background. Remember my screen is on LOWEST brightness level and I barely use it.

Stock XXKI3, (2.3.5) I have several mods though.
If all else failed, try shutting down your phone, take the battery out and clean the battery contact points. Dirty contact points might be the culprit.

So here I am, upgraded from the GS3. I understand that the ME7 radio is locked and that safestrap is the only option. But here's my dilemma. I used to get 14+ hours of battery life on my GS3. Now I'm lucky to get 8 hours, if I'm not touching the phone whatsoever. I've tried stock, Jellybeans, and Darkslide (seems to be my only options but feel free to prove me wrong.) Is this normal? Do I have a defunct device? This just seems extremely poor to me... They can't advertise that this phone is so much better if it's getting less battery life than the fricken S3...
Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference.
I also am pasting a picture of my battery in stock. You can see that in one day, I have to put it on the charger. Yes, I use wifi, but I honestly wasn't using the phone (and I do not have my apps installed.) The first fall on the graph is me using netflix for an hour (battery decline here is understandable). The second fall is my phone sitting on my desk while I'm at work. I'm on my computer, not my phone... and it's almost declining as much as if I was watching netflix. I've restarted it.... used the android task manager to kill the ram... you name it... Every rom I flash I've flashed is like this. It's astronomically frustrating...
I get awesome battery life with Hyperdrive have you tried that at all?

It's obvious that some apps you have installed are causing this, I can get 14+ easy on mine. I highly suggest using Greenify to hibernate misbehaving apps and try to use auto-brightness if you can stand it.

A different rom wont make much difference if its something with the settings or a specific app you have running constantly. Do you have location services enabled. Thats a big one that causes alot of drain.

I had put in a side note above stating that I have been running without my apps installed, so it really can't/shouldn't be a case of misbehaving apps. "Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference."
I will definitely take a look at Greenify, and see if it helps me. Thank you for that suggestion.

"Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference. " I did a ton of reading on this prior to flashing, but from what I see people are only reading my first sentence and trying to answer (which is why the, "Doing a little bit of reading goes a long way," comment irked me.) I have been a rooted android user since Droid X, so I know how to read/research/troubleshoot phone issues. Believe me, I've had to SBF that phone a million times because each flash was like a crapp shoot. This issue however is a commonality between multiple SGS4 roms (Stock, Jellybeans, and Darkslide).
I always shut my location services off the second I flash a rom (unless I need to use my navigator, which as mentioned, I don't have installed at the moment.) But this is definitely a valid troubleshooting question to ask.

Turn off Google location services, see if that helps. That was killing my battery on ME7, same as yours. If your not into rooting, the 4.3 update has fixed that bug, I'm back to 3.5ish hours of screen on time. I did give up root though, so pick your battle i guess.

FYI it is possible to retain root and take the update as explained here: http://forum.xda-developers.com/showthread.php?t=2504408 If you've already updated though you'll just have to wait for an exploit.
To the OP: It's also possible you just have a bad battery... there have been cases of faulty batteries and some were even swelling up so perhaps you could try to get a replacement to see if it fixes it.
Here is a post I made a few months back..I was battling Horrible Battery life (approx 5-10% per hour). Since i caught the culprit in my home netork I get less than 1% drain idle per hour:
"I had bad battery life on my S4 right after release. I tracked it down to Multicast being ENABLED on one of my Access Points. I would recommend logging into your routers and/or) access points and look for anything related to Multicast and Disable it (or uncheck it).
Granted this was for a totally different device (note that my Nexus 7 was NOT affected by multicast) but it certainly cant hurt anything by disabling multicast..If it does, just enable it again.
My S4 was using approx 5%-8% of battery per hour with multicast enabled...once I disabled it, I now drain about 1% per hour.
This took me almost 2 weeks to discover...keeping in mind that my S4 never connected to the affected AP. I use that AP for older legacy devices.....just having it on the network affected my S4.
Give it a try..if it does not work..enable it again."
PS..disabling Google location services also helped me slightly with a runaway battery drain.

Ya, I saw, but not having root is kind of a penance, makes me appreciate having it more when I do get it. I've also decided flashing roms gets old, but for sure I'm missing Xposed framework.

I'm seriously starting to consider that as well... I'm on hyperdrive now but it really hasn't improved that much. I'm currently sitting at 19% since 8:45 am this morning (currently 4:01 PM here). So I'm going to just dip over 8 hours today, sitting at work while on my computer mind you, which is still sad in my eyes...

I'm definitely considering that OTA w/survival mode... no doubt about it.
Today I was using Navigation for about 4 hours straight, GPS and location services on, with LTE, also using Bluetooth the whole time for music and Poweramp with some texting in between. I only dropped 35%. It definitely sounds like you got a lemon (either the battery or phone).
Wow, I am jealous... Yeah, I think you're right.
If anyone is experiencing this problem, I hope the following steps may help.
I would like to express my appreciation to XDA members, who have commended and helped out with this. Credits go to @LordManhattan and @abuihsan . Many thanks for your help.
1/ Do a re-flash: I always thought my device was a c6802, after I flashed c6833, it helped.
2/ Do a factory reset/ Cache wipe/ Dalvik Wipe/ in recovery or in the phone settings.
3/ Install SD-Maid and clean the mess from the programs, also take a look at APPCONTROL to see which is running. You can freeze it here.
4/ Install Performance control to Underclock your CPU. Believe me, 1.7Ghz is far too enough for all the tasks you need.
5/ Use more pwerful tool, like Titanium Backup to stop all the backgound-running apps. You just need to leave the one which were in GREEN color.
6/ Use Wakelock Detector to see which apps get your phone out of deepsleep. Mostly they are Facebook and Messenger. My advice: Disable Facebook notice and if you don't use chat quite often, don't install facebook messenger.
Hope these help.
Personally I had tried a lot of methods, including checking the processes and re-insert the memory card but no such helps. Therefore, if you need any advice or any comments, feel free to send me an PM or reply here, I will gladly help you out, like what the community had helped me our of my situation.
Hi everyone,
Recently I just bought a ZU from a local vendor here. It runs 4.2.2 with no problem. However, I want to get rid of the *new system update* and I also want to use the xperia Themes, I decided to upgrade to 4.3.
My phone model is C6802, and I chose the file here : http://forum.xda-developers.com/showthread.php?t=2453921
The upgrade went through fast and smooth, as I had experienced in many Sony devices.
However, after getting to 4.3, I had noticed some problems as follow:
+ Heat: Device heats up very fast, even left alone. Just imagine you have the phone on 100% battery lying on your table, a moment later it heats up and the battery drops dramatically.
+ Battery drop: Just as mentioned above, the battery drops quickly. I do not expect extreme battery life on this device, but since 4.3, it is too low, I can barely make it to 6 hours without doing anything consuming battery.
+ Process: When checking the battery, I notice that most of the process that takes up battery is Android OS, which nearly 50-60%. I use the phone frequently to answer SMS and call, sometimes play games. I think that the most used applications should be the bad-ass screen?
I am running on the 14.2.A.0.290 with R4B.
Anyone had experienced this problem before, or know a solution to fix? Will clearing the Dalvik Cache help? I had re-flash several times but the problem is still there.
Many thanks in advance.

Sounds like somethings has gone wrong in the update process.
Have you tried backing up all your data and doing a factory reset?
I do not think clearing Dalvik will help you here, sounds like something else is acting up. You could try to install one of the apps designed to detect what is causing the wakelock.
I'm not at my Android tablet at the moment, but I think I used this when I had this problems myself on my Galaxy Note: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector

First of all, thanks for your reply and suggestion.
I had tried to flash the roms multiple times, but the problem still exists. Furthermore, I even flash back to 4.2.2 and the problem is still there. The phone heats up slowly and battery runs out pretty fast.
I had installed the Wakelock Detector on my device and I will update the situation tomorrow, I will leave it there for a night and see the status tomorrow.
Did you wipe after updating? I had the same issue when i updated to 4.3.
Correct me if I'm wrong, but as long as he's been downgraded to 4.2.2 again, he'd have to wipe. At least that is how it was on my Xperia Z.
-KJ
this might not be related, but I've been noticing much worse battery life today than normal! i normally only drop about 50% in 24 hours, but today I've dropped 30% in just a few hours. Android OS seems to be doing it...
no real heat issue tho, maybe slightly warmer from whatever the OS is doing, but nothing too major. running stock rooted 4.3
had that on my Xperia Z on a 4.1 or 4.2 build (dunno which one). Sounds strange, but simply turning off the sync fixed the problem, give it a try :laugh:.
Hope it also helps on your XZU.

At first I did not choose to wipe Data in Flashtool, then I flashed again, this time I checked everything.
the problem still exists.
UPDATE:
Yesterday after working hours, I had rooted and installed BetterBatteryStats, Performance Control to monitor the system. I also had WaveLockDetector and Titanium Backup installed.
It appeared that the CPU runs all the time, in the highest state (2.15 Ghz), the phone never goes to DeepSleep and Awake all the time.
On Performance control, I had underclocked the CPU to 1.5Ghz and the temperature seems to be cooler.
I had tried to freeze a lot of applications via Titanium backup but so such luck.
Still researching.
However, many thanks to your kind replies. At least I know that I'm not alone with this problem :good:

However, many thanks to your kind replies. At least I know that I'm not alone with this problem :good:

I ever had no deep sleep problem with 4.3, even in stamina and airplane mode, and with location-off too, I checked with BBS and found the 'trigger' is a process under google now app. I use GREENIFY and get the google now hybernated. Everything fines now and I still can use google now as it only hybernated when not in use : )

hey, thanks for your reply. I did the same to you, even with Titanium backup to ensure this will never shows up again, but CPU keeps throtlling at 100%. I still can not find an answer to this 100% thing. now the phone is quite hot in my pocket, I decided to put in my bag and even turn off to keep it from heating.
I will try another rom and update.

do you use any cleaner/task killer app? before trying other rom or update, maybe you need to uninstall it, reboot recovery and wipe cache and see the result.
I don't know if this is relevance but while using greenify I also uninstall the previous cleaner app and replace with another one that I think is better.
now my c6833 has great deep sleep.

Hi, Thanks again for your advice.
Would you please give me the name of the cleaner apps that you think are way better?
Are you running on 4.3 stock or on some modified roms?

The thing is, you don't need a task killer/cleaner app. It was useful way back on Android 2.1/2.3, but you shouldn't use it at all on 4.0+. You're actually making things worse.
mine has been heating up as well. the battery isn't draining like how yours is, but any kind of use will heat the top back side of the phone. I checked and after killing all apps, my cpu load was still around 65%. is that normal? no custom flash here. locked bootloader. updated through pcc normally. I'd imagine this is why 4.3 isn't running as buttery smooth like everyone else.

No, that's not normal. Mine's around 20-30 degress celsius (depending on what i'm doing). Even streaming 1080p videos shouldn't make it hot or even mildly hot. When i had the heating problem, two cores would always be stuck at 2150 MHz. Now one core is active at 960 MHz when the screen is on. CPU load is around 20 and 60% (single core). Temperature is currently at 26 degrees. Also, stop killing apps and processes. Most of them are set to start automatically, so when you kill them over and over again, they'll start again and they'll use even more battery. Android is built to manage resources very well on its own, and it's not operating like Windows or any other computer OS. Just leave it alone unless something has gone rouge and you don't have a choice.
I'm on stock 290, rooted and extremely debloated.
- Current battery level: 88%
- Current uptime: 3 h 30 min
- Current screentime: 1 hour (browsing etc.)

hmm... yea that sounds like the problem i am having. im noticing two cores stuck at 2150mhz with a third kicking in here and there. how were you able to fix it? just a fresh install of .290?
so as far as the apps go, i have Du Battery Saver installed and the "optimize" button is supposed to clear up some of the background junk. are you saying that i should leave the optimize button alone and just let android figure itself out?

What i'm saying is that you should uninstall that crappy app. Task killers were useful three years ago when Android devices had slow processors and low amount of RAM. What you're doing now is killing everything everytime you tap that button. WHY do you want to do that? What's the point of having 2GB of RAM when you don't want to use it? Are you always killing processes on your computer too? Would you do it if your computer had 32GB of RAM with 30GB available? Unused RAM is wasted RAM. Android is a modern OS that can handle this on its own. If you only have 300MB RAM left and you want to play Asphalt 8 which requires (i'm guessing) 500MB RAM, Android will find the oldest and less frequently used process and kill it. It's that easy.

ok. so I haven't done anything at all to remedy the situation. I figured I'd ask about it before messing it up myself. I upgraded to .290 via pcc. it updated fine with no errors. once it was done updating, it was hot and battery was diminished. I had seen on another thread that most people had that happened so I didn't see it as an issue, just a side effect of the update process.
I have been checking back to see if anyone was having heating issues with 4.3 after the update and didn't hear about it until I had seen this thread. the OP stated he flashed .290 on his 6802 and is rooted. I am not, so I wasn't sure if the steps he was taking were the same given my 6833 being completely stock.

Hello everyone,
My s6 Edge does not go to sleep. It drains huge amount of battery while idle.
I need urgent help. I have disabled all AT&T bloatware. But it still does not work.
I have also tried hard resetting it, it does not work. Battery continues to drain.
Thank You.
Is this something new or has it always been like this? Btw, which version of LP are you on? 5.0.2 or 5.1.1?
Its new, LP v. 5.0.2

5.0.2 seems to be notorious for battery drains...check if your device has the 5.1.1 update which seems to be better in terms of RAM management. Also, are you data or wifi...if on data, then LP is again notorious for a world famous "mobile radio active" bug...it's all over the web...So, the best solution would be to either put the phone in deep freezer until Google fixes the huge bugs in LP or sell your phone...just kidding...
After updating your device (if there's any), do a factory reset...it should solve your problems...hopefully
Does not go to sleep? Check your settings about screen timeout..The battery drain can be fixes through system update..if samsung has any update ready

I hard reseted my phone, disable all bloatwares, haven't installed any apps, haven't signed in to anything (even google, only signed into samsung account). charged to 100%. Left the phone for 4-5 hrs, battery drained to 81%.
fliptroniks said:
I was going to say just make sure you dont have too many apps running and you can also download a battery saving app on the play store for free which can help. It sounds like theres something you have running draining your battery though. Keep in mind however that the galaxy s6 edge when charged to 100 percent can hold a charge for quite awhile, but if your only charging it too around 40 or 50 percent it will die rather quickly.

What does it tell you in the battery stats? That's the first place to look. Is Screen at the top or something else like Google Services or a fitness tracking app? Send a screenshot of that as a starter for 10.

Your best bet is to install TWRP, root, and flash "No deep sleep fix", thats if you dont care about tripping knox of course.
Seems like an aggressive suggestion since we don't know the root cause yet. It might not be a wake lock issue; it could be location tracking or updates getting stuck. I'd rather see the battery stats first.
Screen is not even on the list, i haven't used my device for more than 15-20 mins (used chrome & inbox for 15-20 mins in the morning)

Google Services like I thought. There's a number of things that can cause this as it's quite a fundamental service. The most simple fixes are:
- Make sure there's no pending updates in the Play store. These can work havoc with the battery when waiting for manual approval
- If this doesn't work, remove your google account, reboot and re-add it. For some reason this can fix the sync issues that cause drain
- Still no dice? The next one is to backup, factory format then restore your backup. It's a bit extreme but sometimes when you update your software it causes a glitch that only goes away with a factory format
Each time you try a fix, let the battery fully charge then check the stats a couple of hours later.
Thanks for the suggestion, I will let u know the results soon.

You're welcome. If it's any conciliation I had exactly the same issue and fixed it this morning with those steps.
Google services is one of the biggest battery user but it still doesn't explain his erratic battery loss. I never turn off any features and get decent life.

Tried the third step many times before, didn't work.
So, yesterday I tried the 1st & 2nd step, worked like a charm, I was happy but today, the same results (battery was draning like i was playing games). So I completely removed my google account and left my phone for a few hours. Here is the result (see attached). As you can see no Stupid Google Play Services in the list but what is eating my battery ????

Again, LP has a world famous bug called the "Mobile Radio Active" bug. What this means that if an app uses the data services for some odd reason LP keeps the mobile radio open even if the app does not need it any more...So, for all you know ur issue is Android related and not your device specific. Oh btw, the upcoming M also has this confounded bug...so I believe we will be plagued by this bug for the foreseeable future...And I dumped my iPhone for this buggy Android...Dang!
How is your reception, If most of the time your phone struggle to get reception, it may be part of the problem, just my 2 cents, not an expert, but myself trying to get rid of the google service battery bug...
Better battery stats would give detailed information as to the cause, yet it requires root on all lollipop devices. Helped me find the exact cause of my phone never sleeping
Hi!
I need some advices. I own a Tab S3 SM-T820 (new) for three months now. All is OK. But, all of the sudden, after testing a LineageOS build (latest for bonuzz), I wasn't satisfied with battery drain, so reverted back to stock nougat. But battery drain never went away! Usually, while screen off overnight, the battery would drain 1-2% (I always switch off my wifi). But now, same situation, but drain is 15% overnight. I have done a lot of research, used tools to pinpoint wakelock apps, etc. But, according to tools, my tab goes to deepsleep but drains anyway. I cannot count the number of times I reseted my tab to stock thru Odin. Witouth installing any apps, no root, battery still drained. I even took out my SD card since a defective SD card could cause drain. I tried to use battery saving apps (greenify, amplify, etc) but no change. While screen is off, I will loose 15% within 6 hours. I also have cleared the system cache (thru TWRP recovery) and apps cache, with no effects. While screen is ON, battery drain is normal (1% every 5 min.)
Now, for the warranty, since i purchased this Tab new, I approached Samsung for advice, but since I bought it on Ebay, I am not covered by the warranty.
As anyone experienced something like this? I am beginning to think this is an hardware failure. But it is new. Any advice is welcome.
Thank you.
Allan
Check to see how you have Wi-Fi set up during sleep. If you choose never you'll have very low battery drain over night. I often see 0.

Then you need to see what's causing the battery drain. To do that you'll need a battery monitor such as betterbatterystats or GSam. Both will give you more info if you're rooted.

Try turning off your mobile data at night. It stays up and parties while wifi is taking a settings enforced nap.
Hi! I don't have the LTE model. But I will try Amplify with extreme settings I found elsewhere on this board. I hope it will at least cut in half battery drain. I also tried to remove my smart Samsung cover to see if it caused the drain, but it is not the case!
I would try a firewall, restricting all outbound traffic and setting airport mode, wifi off. Also turn off tethering & account syncing, anything that could be attempting to 'get out'. If battery life improves, allow apps back one by one until battery life improves. Same with settings. If battery drain continues, you've at least eliminated outbound intentioned activity as the culprit.
Then I would try monitoring app activity. There are apps out there, but I can't make recommendations, since I've had no personal experience with any. Try a search on the terms:
--> android app activity monitor <--.
Not sure if there's an app that will check battery condition? Or you could take it somewhere to have the battery checked.
These are all abstract suggestions. I wish you luck in finding your issue.

WIfi battery drain has been present on the Tab S3 since day 1 of release. Hoping Oreo would fix this problem
Well I finally did the ultimate test to sort out if the problem was hardware or software. I factory resetted with Odin on latest XAR AR2 firmware (again...), wiped all data and started the tablet fresh new. No connection to wifi so no apps were installed and no stock apps were updated so to test the tablet as close to stock as possible. Wifi was off, so was location. Wifi set to 'Never'. Battery was at 100%. I let it sit there overnight. This morning, battery was at 82%... So I suppose that means hardware problem. I have a Samsung service center nearby, so I will call later today. Really hope it can be reapaired or I will have a $$$ garbage. Thanks all for your advices.

Just ran across this post. Seems this user solved his battery drain issues by turning off auto updates in developers options:

I have the 825 model, and with two different firmwares (AQJ1 and ARA2) never had the problem.
Wifi during sleep is set to never and I don't even lose 1% overnight.

Nice find. But this setting is already disabled on my tablet and I still have battery drain.
The tablet finally returned from the repair shop but no repair was done to it. Still, the technician is convinced that the problem is software and that reflashing the firmware would do the job, just not with Odin but with their 'servicing tool' provided directly by Samsung Canada. The problem is they cannot flash a US tablet with this tool so I would need my tablet to be serviced by a US shop that has the right tool. Anyone know of a 'Samsung servicing tool' other (and probably more powerful than) Odin that can be downloaded? Or is it the firmware that is special? To be continued...
I just talked to another technician from another repair shop and he confirmed me that Samsung Canada will provide no help nor tools to repair/service tablets and phones purchased in the US. Sad! I already sent an email to Samsung US to see if they can provide any help.

Search for 3c battery monitor widget on play.
There is no app more detailed in what is using the battery.
This app gives very comprehensive details on power usage.
I'd also try airplane mode over night. This is all radios completely off.
Also regarding the software.
There's nothing that the service centre can do that you cannot already do your self with ODIN.
If a complete flash and wipe doesn't fix the issue then it's likely hardware.
Maybe it's just the battery at fault. Not particularly difficult to replace for a DIY 'er

Thank you. I will try that app right after work! About Odin, do you think Samsung stock firmware image replaces all the partitions (ex: MISC, HIDDEN, etc..) or only SYSTEM, BOOT and DATA? Because I am beginning to think that one of my partition got corrupted. I remember, when flashing back from LineageOS 14.1 (march-18) to stock rom, restoring Superuser, DM-verity hack and my backup thru TWRP was extremely slow (about 5x slower than normal). But after a reboot, every went back to normal, but drain in deepsleep began...

Pretty much all partitions that are important or ones that could affect the running of the device.
There are many partitions not flashed, but these wouldn't affect the running of the device nor would have been touched by a custom OS.
Partitions like misc, hidden etc. can be wiped via recovery.
