It has been almost a month since I've gotten the Galaxy S2.
I literally waited like a longing puppy for almost half a year to get this into my hands.
I have to admit, it is one of the most beautiful creations to ever grace our earth, but gosh, it has this one big, big flaw... (for me) battery life. Before you dismiss this as another battery life complaining thread, hear me out...
I have tried EVERYTHING.
Ever since 2.3.3, battery drain. Then 2.3.4 was announced... NO MORE BATTERY DRAIN. The news caused a burst of elation, but it was all too brief. Flashed to 2.3.4, same deal.
I've tried all the ROMs-- Litening, Villainrom, Cognition, Infusion (now defunct).
I've tried several kernels -- the standard CF kernel, neophyte's, mirage, etc.
I've calibrated my battery after each flash.
I've tried downclocking it with SetCPU.
I've frozen so much with TitaniumBackup.
Dormancy settings, system update settings, modem roms, I've tried them all.
I even purchased, in desperation, a third party battery which claimed to have 2000mAh capacity.
All to no avail. Nada, zilch, non. NOTHING has worked for me.
Last night for example, I had charged my phone to 100%. When I woke up 7 hours later, it had fallen to 63%.
Therefore can deduce that consumption is is about 5% per hour with screen OFF.
I have also made it a point to test a different ROM/kernel for at least 3 to 5 days before I make a change.
Now I really don't know where I'm going wrong, yeah I do have a few widgets and stuff, but what is a phone like this without widgets?
I am getting so sad over this issue. This phone is so perfect in every other way.
Why? Is it just me?
One no mention of actual battery life .
Two phones get fed up with multiple roms kernels etc rammed down their throat and dont work well .

What exactly do you mean by 'battery drain' ?
Starting an new battery drain thread without even describing the type of battery drain is not a god start for this thread.
What is your idle drain? (% per hour when not using the phone).
How much "display on time" do you have when the battery is starting to be empty (no guessing, hard number from the battery menu please). A lot of people underestimates how much active use they have with SGS2.
Please also add graph for battery statistics, both the first page and also for the battery graph (press the small graph on top).
Just trying different ROM's in order to solve a battery drain issue is a bad idea, it is much better to find the root cause of the battery drain and solve that specific issue.
I mean I leave it overnight, and it falls from 100% to 60%.
It has never lasted me beyond 9 hours with mid level usage.

Apologies, my post has been updated. I don't have a good graph with my now since I'm charging, but I will post one up tomorrow.
Do widgets really make a big difference? Because that's the only thing that I have not really tested.
Could very well be a misbehaving app or widget. My phone in idle uses 0.5%-1% an hour with wifi on. Without wifi it goes slightly faster strange enough. I have some widgets that update every hour, gmail push, whatsapp and Samsung account sync.
Test without syncing and widgets and then re-enable things one by one to find the problem.
Another battery thread. That really IS depressing.
i just got my phone few days ago, battery life isn't great so far but it isn't as bad as your case.
I would recommend you do proper tests after starting fresh. flash a stale official rom, keep the phone barebones, dont install apps etc.. then test bat life with phone call usage.
Then slowly start adding and enabling things like gps, auto sync, background data and so on, till you find the cause. I think the battery life thing in the settings can help too.

40% overnight is huge, I get approx 5% in 7-8 hours.
With 5% drain per hour with no usage, haven't you tested to turn off things until the drain stops? I would start with wifi, SGS2 doesn't work well with some routers. Then just continue with the usual suspects: widgets that connects to internet etc, email sync, facebook etc. (freeze with Titanium)
Do this systematically, you could turn off several things at once, but not too many, try to find the real cause.
There is of course a possibility that your phone is broken, but that isn't my first guess.
Why does no one try Juice defender???

Oh yes, that night the 40% drain was with Wifi on, and I heard that there have been issues with the DIR-655, which I am using.
Anyway, even with wifi off, my battery life fell from 100% to 83% with a very slimmed down ROM, everything that could be frozen, frozen.

I would, but the thing is, the battery life should not even be that bad in the first place.
Sounds to me like you have a rogue app. I get 12,14 hours of heavy usage with brightness set to roughly 75%.
Don't flame him. He has tried alot things prior to posting. This is the place to post. Try the criskelo rom. It is a great rom with great battery life. Freeze wifi sharing. Delete apps at the beginning that you don't use all the time then add extra apps one by one and see what impacts the battery level the most. Check update schedules for things like news widgets and beautiful weather-I have mine set to six hours or so. There is absolutely no reason why you can't last a full day with 30-40% left.
Well, first of all, it's just a phone, although an expensive one, so no need to be stressed.
Secondly, it sounds very much like you have a faulty battery or device. Maybe you should have replaced it as soon as you noticed the problem. There's definitely something wrong there if it goes from 100% down to 60% overnight (assuming it's not heavily used during that time).
You already tried most of the things that I would do to tackle the issue. Try swapping batteries for a few days with somebody with the same handset, and see what happens.
Good luck!
For giggles, why don't you hard reset your phone? Then, instead of loading tons of apps of questionable quality, task killers, memory managers, and battery monitors, just load the stuff you need everyday. Things like e-mail and social stuff. People that haven't tortured their phones with excessive crap seem to get better battery life without even trying. With over a hundred apps, all the syncs syncing, heavy Wi-Fi use, and Exchange push I'm now up to 14-18 hours with moderate to heavy use. If the experiment works, start loading the rest of your stuff on your phone to see what the impact is.
Another thing to consider is your network connectivity. Your carriers signal strength and infrastructure could be part of the problem. Certain carriers and locations seem to contribute a lot to batter drain. Also, the SGS2 is very router sensitive. It likes Netgear, D-Link not so much.
Good luck.
This is with a screen on time of 2:14 too, and overclocking to 1.52gHz
There is no battery issue, this phone has twice the battery life of the desire hd and thats a fact, i have not changed fast dormancy or anything, this phone is king for battery life.
Played games and browsed internet, i would say medium heavy usage
Using 2.3.3 KF3
Also if you had a laptop that lasted 10 hours with 63 remaining wouldnt you think that was good? This phone is the absolute top dog, i would even say its better than IP4 for battery now
Also used cardiotrainer to track my run this morning using GPS, ran for 30 mins and lost around 6 percent... Amazing!

Yep Juice defender sucks, and is not needed really...
You either have a rouge app sucking the life out of your phone,
Your syncing at too short periods (mine is set to 1 hour)
Your phone signal is weak so your phone is using more battery drawing 3g from your service provider
Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?
Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.
Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?
It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.
This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.
I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.
My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.
had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..
To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.
To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.
i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call
I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.
Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.
Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.
Ok and which stock rom does not do that?

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.
As the title says, standby battery is awful.
I have all the bloatware disabled, only things on push are gmail and facebook messenger.
Cell standby is also sitting at 20% battery usage, no matter what, 2nd on the list behind screen time. Note 3 had exactly the same issue where cell standby is concerned. None of my other phones have had this issue, including my S2 with buggy as hell CM11, OnePlus One, Moto G LTE, etc.
No matter what I do, even with everything disabled and on airplane mode, there's a constant 1% battery drain every hour.
In my Note 3's case, this only happened on stock samsung firmware. When I flashed CM11, the issue went away completely. Something like 0.3% drained per hour instead.
So to me the issue is with Samsung's crappy software. I know the battery life was woeful on the Note 4 anyway before an update came in to fix things up a bit. Maybe they're saving the fixes for 5.0?
I know a new update for the N910C was released a couple of days ago too, but not available on European models yet.
Anyone else having these issues?
I dont have this issue at all my friend if i were u id try a complete wipe 1st, some people have had this issue too so returning could be an answer
Same here...
I only lost 4% battery overnight and don't have this problem too
20% battery loss on standby but mobile data was enabled.
^ you may have a bad app and/or bad signal
I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.
Ignore the time its been on, the same thing happens during a day of heavy usage when in standby, same level of drain constantly.
1%+ may not seem that much to a lot of people, but with my usage i should get through 2 days regardless. It should be less than half of what it is. From the curent reporting in the battery stats, im losing almost 50% of my battery in standby over a day and a half or so.

The only things enabled for sync right now are the basic google apps such as chrome, calendar etc. They rarely sync though, and no other phone I've used in the last 2 years has had an issue with them.
Samsung sync constantly returns errors so I leave that off.
Last thing I'll be trying tonight is a full wipe without disabling any built in apps. Its doubtful, but maybe one of the core shamsung apps are trying to communicate with a disabled app or something. I really don't know.

Any update?
My n910c is terrible too. 15% battery loss in 3 hours of standby alone! Wtf! Tried every battery saving trick' no location on etc...
i would suggest u do few thing while u get on bed next time,
Full charge your phone and unplug before you on bed,
1. Restart the phone while on charging,after restart go to home screen and lock the screen and unplug then go to sleep,check it at the next morning u wake.
2.Left the phone with your daily apps running,full charge and unplug then go to sleep,check it at the next morning too when u wake.
this is how i solve those apps running not right.
like the screenshot below,
An apps running at night drained 30% battery within 6hours & 30mins & without switch on the screen or touch anything since i'm asleep *with wifi on*
2nd screen shot shown that cm browser running and consume 94% of processing among 30% battery
while cpu only running 20mins since i had weather & sync on during night.
After that i report to cm team and they send me latest version,
after re-install my phone just back to normal.
now my N910c note 4 is consuming 1% every 1.5hours standby with wifi/3g connected *my area 4g only 1~2 bar so i changed to 3G*
average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

I did a full wipe, installed ANK5 update, unplugged at 10pm at 100%, woke up at 7am with 97%. This is what it should ALWAYS be.
However, after the 2nd charge after the full wipe, it's back to what it was, if not worse. Last night I unplugged at 11pm, woke up at 7am with 92% left. That's bang on 1% an hour again.
There is nothing keeping the device awake at all. It's very frustrating.
I can only assume Cell Standby is so high due to the fact that the phone isn't actually doing anything while the screen is off. After a 20hr day with only 1 hour SoT it's sitting at 72% battery left, with cell standby at 31%, just above Device Idle at 29%. It's a mystery to say the least.

Thanks for your post. I'll definitely try restarting etc again beforehand. I'm also considering another wipe, as S-Voice being disabled seems to cause quite a few errors in the camera app. The battery drain increased after I opened the camera app too, even after force closing etc. That could just be coincidence though.
1% every 1.5 hours still seems like a lot to me, but it seems like you have a lot more apps and things running, so it's actually very good!
Very tempted to just root the thing now and throw on a debloated OS and custom kernel.
Last night i go sleep with 10% of battery left, ( im not force closing any application at all - just exit ) when i wake up ( about 7 hours of sleeping ) phone was showing 8%
No data/wifi/gps etc. If you are not using mobile internet, switch to GSM! It takes more than 30% less battery power than 3G
I'm thinking this is a hardware fault of some sort. Maybe battery, I'm gonna replace and see cause tried from full charge placing it in airplane mode to see if signal was causing the problem, didn't touch it, screen off whole time for 2 hours. Upon looking at it I saw I'd lost 7% battery! Omg! In airplane mode?! In 2 hours?! In standby?!!
In normal use there are no Rouge apps or strange readings in battery stats at all. May be hardware fault.
I've had the N910K exynos, 6 hours plus sot battery life
I've had the N910F snapdragon, 6 hours plus sot battery life
This n910c give me 3 hours sot. I'm pissed lol. Right off!!
Thats really weird, it can be issue of the battery. My 910C has about 8/9 hours of SOT ( wifi only ).

Your mobile signal is very poor. I believe you have full bars but your screenshot ... well it shows us that your reception is poor. It may be one of the causes for your fast drain...

My SoT is fine if im only using it during 1 day. Its usually close to 6 hours. But its not heavy usage, just browsing mainly.
Let me know how the battery change goes. Im likely going to order a spare anyway for when im away from home, so will also report back.

At work its pretty poor, usually a bar or two on lte, but no other phone ive had has displayed battery drain like this in standby.
That still doesnt explain why it drains 1%/hr with nothing happening at home though with 4 bar lte and full wifi signal.
Ive also noticed voice calls are taking up significant battery. A 3min call used more battery than 20 mons of screen time at half brightness apparently, unless thats normal.
If its normal, then to me the cause seems to be battery related. If not, then faulty cellular chip.
Also heres some more screenshots.
This is over the course of the day with barely any usage.
The chunks where its awake, that's just when I'm playing music, not a rogue app.
Note the big standby drop at the start, then the standby drop later, both completely different amounts of drainage, yet both when doing nothing.
My Essential PH 1 is draining a lot.
Phone idle is taking most power with approximately 17%. Screenshots attached.
Can you please advise if this is normal and ways to minimize battery drain ?

Are you showing off? because those are amazing numbers. You're on track for 35 hours! I get around 26. Your bigger killer is What's App, but that's expected for a Facebook app. 17% for idle means your phone is on and doing nothing 17% of the time.

Nope I am not showing off, I think i am having huge drains when I am asleep. Most of the time in that graph is idle time so i am thinking it should be better ?
Again I moved recently to droid from iOS so i am unsure of the droid power management baselines.

Cool. I didn't mean to seem mean, but those are good numbers. If your phone is on, and you have push notifications (pretty much every social media app, phone, sms, etc.) you're going to have drain. Even if the phone was off, the battery would drain somewhat. But you have What's App and other chat apps, so that'll use battery, even if your asleep, the phone isn't. It's the only way you would be able to receive calls, text, updates, etc.
That 17% looks steep, but it's all relative to a small screen. over the span of 20 hours and you still have almost 50% battery, especially with "free" apps that are basically advertising engines pushing ads at your every minute. Having Phone Idle at the top is not a bad thing, it just means you don't use your phone as much as you use What's App.
1% per hour is good, better than our S8 even
I had enabled "Cellular data always active" and it chewed through my battery life. I turned it off and can now last 1.5 days on a charge.
My phone is draining 12% overnight. And phone idle is top of the list. What does this phone idle do? There was a random night where the phone only dropped 1%. But most nights, it's draining around 10% with phone idle at the top.
Update: setting wifi to not stay on while phone is sleeping seems to fix the drain issue.

Does disabling it affect receiving messages that rely on mobile data such as WhatsApp?
Where is the "cellular data always active" setting? I don't see it. Have not updated to run Oreo.
My battery was dropping from 95% to 5% overnight. Did a factory reset which helped, but I'm still losing 17-20% overnight. Seems odd to me on a brand new phone, but I have never owned an Android before. I have blocked notifications and location services from nearly all of my apps. Any advice other than what has already been posted?
If your losing that much overnight it's probably a bad app.
I don't use it, but have read that the Facebook messenger is good for that. As in eating up a battery overnight.

I can promise you that that's not normal, especially for this phone. Overnight battery loss is minimal, 15 hours of idle with a 10% drain is what I'm getting. That's pretty amazing. I'd check your apps and ask the general android forums for advice. I also bet there is a rogue app draining you juice. chat and social media apps with all their pushed content and friend updates are huge battery killers.
Install accu battery ,charger to full last thing at night ,don't touch through night ,then see what's draining battery ,mine drains by about 2/3% through 8/9 hrs at night

It's under developer options settings. I have mine always active without draining my battery noticeable.
The social media apps such as snapchat, facebook, twitter, etc... are the ones draining your battery while your phone is idle so you need to disable their background data running.

The option to Cellular Data Always Active is on the Developer Hidden Menu. If you have it enabled you should be able to turn it off.
Thanks to all for the replies. I thought that restoring factory settings had helped somewhat, but it turns out not to have. Battery has just depleted from 100% to 67% in 3 hours while the phone has sat idle.
The only social media apps I have installed are FB and Whatapp. Notifications for both are turned off. Location services for all apps are also off. The only apps I have installed have been download from the Play Store and have run on my previous phones without causing any trouble. Those who replied all suspect a bad app, so I have installed ACCU Battery as suggested to see if I can nail it down.
Thanks again for the responses.
Try this for one night. Right before bed....
1. Turn OFF WiFi
2. Reboot phone
3. Leave WiFi off after reboot
There is a bug in Google Play Services that affects many people on many different phone types since the November updates.
When on wifi, in certain circumstances (many theories on what the actually trigger is) it will cause Google Play Services to run non stop on certain WiFi networks causing huge battery drain.
In this particular scenario, turning off Wifi does not stop the battery drain. The phone has to be reboot.
I don't know if that is what you are experiencing, as you didn't say if it was an app or system taking so much battery, but I thought I would mention it in case it helps.

Why don't you look in settings/battery and see what is using the highest percentage of the battery?
Have looked in Settings/Battery, but am not seeing anything there that diagnoses the problem to my understanding. Highest use shown is Chrome (4%), then Screen (4%) then Google Play services (3%). ACCU Battery app shows the same. Battery is still losing 10-12% of its charge per hour while the phone is idle.
Have sent a message to Essential support to ask if they know anything about a bug in Google Play services causing battery drain. They have so far only suggested rebooting to safe mode and doing the reset to factory settings. Hasn't helped.
Will try shutting wifi off, rebooting and leaving wifi off tonight as suggested. Not really sure where to go from there even if that does save the battery, as a phone that has its battery drained just by being on wifi is useless to me.
If turning off WiFi and rebooting helps reduce system cpu usage, it is a bug in the software and not the phone. I can reproduce that specific issue on my pixel 2 and Samsung Galaxy s8, too....
If the CPU usage isn't from system, though, or turning WiFi off and rebooting doesn't help then you obviously have a completely different issue and need to troubleshoot further.

Update:. Nothing Essential support has suggested has helped. Battery is draining to zero overnight while phone is idle both when connected to wifi and when not.
Upon learning that I had purchased the phone at a Telus store in Canada, Essential have said that they can't help me further and have referred me to the store for assistance. I'm disappointed in the lack of support from Essential.
I have now had my galaxy s8 for over a year and i have noticed my battery life hasnt always been that great.
I have noticed that over a total day i only get 2-3 hours screen on time.
For an example when i go with the bus home for 25 min my battery often drains over 10% without even using the screen for 25 minutes.
Once i installed another rom called lightrom or something over the renovate ice rom and it got much better the first day but second day when i got more apps on it begun to be bad again.
I then went back to renovate ice rom and i was back to bad battery life again when i installed all my apps.
BUT in this case i have an app called greenify and i greenify all my apps in the background but i still have a massive standby drain
I have never found out what has caused my problem but for sure it cant last a whole day
I have this thought that it can be weak signal but i have disabled the option "Keep mobile data turned on" and followed multiple tutorials of how to make battery life better
AOD off, Location off, Wifi off, bluetooth on ( for gear s3), nfc off,
So i only use bluetooth and mobile data.
I apreciate all help

Since the problem starts when you install your apps, I would start with checking which apps are the culprit. Apps like snapchat and Facebook are notoriously known for unreasonable high battery drain in standby.

Personally I have auto sync off, no battery saver, amplify, and display set to WQHD but I also use dark themes via substratum and my average battery life is roughly about 8 hours SOT
Edit: Sorry meant to quote OP

I have deleted Facebook a couple of weeks ago and that made no huge difference. Though I think snapchat may be the one. But I often have it hibernated
