JI6 update: a *serious* let-down, in my opinion

So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip

For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !

Better than Windows NT = 1.6

Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.

Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.

You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.

Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.

You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

I'm having terrible battery life as well.

i'm 24 hours unplugged, sitting at 27%

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...

Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.

You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.

Wholy crap gingerbread has awful battery

I wouldn't even say I use my phone frequently. When I used the miui or however it's spelt rom I would have 60 percent to 30 remaining each day. On gingerbread? I'm down to 15 percent every day and every night my phone has shut off due to lack of battery.
Isn't there any rom with excellent battery life? That's all I want, I use my phone for tethering.

i put CM7-RC2 on my device yesterday and it's the best battery life i've ever gotten.

Gb battery life owns, u got something else going on

No he doesn't, i've measured religiously since the original nexus shipments and this is by far the worst

My battery was really bad but now it seems to last me 10hrs & up which is weird for a phone to last me that long. I really think theirs an app or bug running the battery crazy I don't use any task managers. Their was a thread somewhere saying to run your phone on recovery mode and to press on the reboot/restart and battery get better I did that so maybe it does work but I highly doubt it.

I can vouch for poor battery too. I am on CM7 RC2 and I can't even make it through a day with light use. By light use, I mean practally not using the phone at all.

My battery life seems to be better than ever. Some 10-20 percentage units more left in the evenings all down the line.
Edit: Stock GB, no task managers.

I agree. Gingerbread has been nothing short of AMAZING for my battery life. The battery life is so good now that I stopped using my spare battery altogether!

Did you happen to do an Update or a full install when you got gingerbread?
Some suggest that it's due to the update process.. so you might want to try a full install:
http://android.clients.google.com/p...b119f8.signed-passion-ota-102588.656099b1.zip
Remember to wipe your cache first..

What i noticed is taht custom roms use more battery than stock rom. this is for me i don't say that it is like this for everyone. But with gigerbread i got the best battery life. i also think using apps from SD uses also a lot of battery life, but again i have no other choice to low on memory.

bug
I had the same problem. I am on stock gb.
Just set wifi sleep policy to never. It will last 2 days after that. It is definetly a bug.

Seems to be a real mixed bag with GB on N1's. Lots of people saying "better battery" many others, myself included, reporting much worse. For me, I experienced very poor battery life right from updating to the stock GB using the singned passion .zip file. Even did a factory reset, and only reinstalled my daily used apps and it made little difference, then I went back onto a MIUI rom for a few days and battery life was wonderful again.
Then early this week I flashed to CM7 RC2, and for two days battery life was the worst I've ever had.
Had been seeing a few comments on different forums of people who had the same problem swearing black and blue that after they changed the wifi sleep policy to "always on" their battery life improved dramatically on Gingerbread.
I know if sounds backwards, and that is why I was sceptical for ages, but last night I made the change to see if it would make a difference for me today and all I can say is WOW!!! Phone had a real test today as I started work really early. As of right now the phone has been off charge for 16 hours.
Half a dozen or more voice calls, minimal text, my usual wifi and 3g data, about 10 min of streaming video over wifi and about 1/2 hour in total running Navigation.
There is no way in hell my phone would have done all that and even lasted me 8 hours prior to changing the wifi sleep policy - so I think there is definitely something in it.
As for the ppl who aren't noticing bad battery, maybe they already had theirs set this way - or maybe it's an issue only effecting certain batches of devices (like the wifi reconnect issue which seemed to be pretty common pre froyo)

it /WAS/ terrible at first. Really, really dire, but it's back to what it used to be, even better now perhaps.
To the OP, do you have WIFI turned on still? I used to leave it turned on and it didn't ever knock down battery as it was going to sleep and not coming back, so wasn't a drain. GB appears to have fixed this, and it was staying on, thrashing the battery.
Turning it off and turning it on as needed only, battery life is now fine.
Do you have WIFI Turned on? Bluetooth? For now, to try and test what's happening, turn off 3g, wifi, bluetooth, automatic date/time sync, and JUST use it as a phone for a day. See what % you're at at the end of the day.
Then we can take it from there.
But I'd be pretty certain that it's wifi related, in that it's now working as it should be, we just got used to it being broken before.

My phone on cm7 rc2 has worse battery than I used to have with wildmonks kernel and cm6.1. Yesterday, the phone was barely used until 8 o'clock at night. It was at 45 percent. After an hour medium use, its gotten down to 23 so I had to plug in the phone....the easiest fix? Keep a charger In the car!

Using stock Gingerbread and I can say that my battery life is decent, better than Froyo for sure. The phone lasts longer than 16 hours and I use bluetooth to listen to music for 1.5 hrs on my commute home. By the time I get home after a long day (8pm'ish), I still have about 20 to 30% left.

I have no wifi no bluetooth no gps and a dim screen.
Tis is seriously crappy battery life.
Does anyone think they can link me to a good miui rom. For me, it seems that gb just wont work.
I am running stock gb then i flashed the root and my boot loader is unlocked.

Listen to this person!
For some reason, since 2.3.3, if you have your Wifi policy to sleep when the screen is off, Android will rip through your battery. You'll notice Android OS taking all the battery on the status page.
Set the sleep policy to never and you get better battery life again. Turn off Wifi manually when you're not using it, even better. Until somebody fixes this bug, I guess it's the only workaround we've got.
More info: check issue 15057 on code.google.com - cant post link due to the newness of this account.

Same here on shorter battery life my nexus one as well post gingerbread ota... I will look into detailed system processes and try to find out why...

Log into latitude and log out. Every time there is a map update it defaults to being a battery draining monster. But in essence. Something to do with maps link to latitude (which i don't even use) breaks my phones battery life.

Terrible batterylife when playing any game

hey guys. check my stats and tell me what you think please: faster discharge than charge....even worse if i dont regulate my cpu to 800mhz durimg gaming...tab doesnt even get too hot so where does all the energy go?
the first image shows one percent takes 1.30min to deplete so i get 150min overall when playing games. also 40% discharge per hour so 2-3x as fast depletion as when browsing or writing with spen. and that even thouh cpu max is 800mhz!

My guess is, there is something wrong with the KitKat firmwares we have. Maybe that's why they haven't released it in most countries.

tried draining it completely last night... started around 8 with the process, 8.30 it was supposedly empty. after that around 15 reboots still possible, 2 hours screen time in download mode and about 20 minutes left to play around with it. battery kept jumping to 3-7% on reboot and then drained again. so lots of juice was still in there.. will see how it does now, that a complete drain was performed

Save your time. Draining and complete discharging is an old trend with batteries, made with older technology. Modern batteries are totally useless to drain, it only calibrates the device. Which can be done by Battery Calibration app.
Save the time and try to calibrate it. Requires root.

I've had this problem for months (strangely I feel like it only became a problem a few months after I bought the device). I've heard some people say it's a motherboard issue and they sent it in to Samsung for repair. Others have said don't waste your time.
As for me, I just grin and bear it... and know that if I play a game I'll need to charge it soon after.

I have the exactly the same problem.. I have tried one of the battery calibrating apps from the play store. Also I have now done a factory reset and also booted into recovery mode and deleted all cache. Then I have done another factory rest within recovery mode. So far seems much better. Hoping that it is fixed.
If not I am going to blast Samsung. I spent the £500 on this tablet and i expect more. Thought this was a premium product. See what happens but I notice there is only a 6 month warranty on the battery so Samsung may try and wash there hands of the situation. Does everyone have this issue who is using kit Kat?
See what happens but we may need collectively 'fight' Samsung if this is a hardware issue. I would encourage people to post there issues here just in case.
Have you noticed when you get to 0% battery life, if you reboot it will probably jump upto 30%? The calibration is well and truly stuffed!

FYI, I just got this tablet this past Sunday and it comes with KitKat. Spend sometime turning off some bloatware from the Application Manager. No root yet for Wifi without KNOX tripping, so I can't disable any other apps. Played around with the tablet a little bit and the battery life is not good.
Stats:
- Wifi Always ON even during sleep
- GPS is ON
- BT off
- Samsung crap-features OFF (Smart Stay, Smart Scroll, etc.)
So it's Samsung and/or KitKat. I can't even tell what caused Android OS to keep the CPU awake for so long. With this, I assume playing game will reduce the battery even more.
12 hours 42 minutes total time since charged
1 hour 34 minutes screen on time
4 hours 23 minutes Android OS keeping the CPU stay awake??

Most likely because you've got location on, and apps constantly requesting your current location.
Location/GPS is the mother of all battery drains especially if you haven't got a consistent lock on GPS satellites

My thought is that if I am connected to wifi, the tablet will use network based location service and not GPS.
I also have GPS ON all the time on my Note 3and it didn't cause this much CPU awake. Both the Note 3and Note 10 ate connected to the same wifi network.

Can't tell much from the stats you've provided.
I'm no expert but I don't think limiting the cpu in anyway let alone so severely will help, most likely make things worse.
Games are normally more GPU intensive than CPU and it's not the frequency that determines power consumption it's the voltage.
800mhz would require less voltage to be stable but if your just limiting frequency, your voltages might still be going up when more resources are requested.
What Rom and kernel are you using?

I meant GPS as in BOTH the GPS hardware and the location-based network. Sorry for the confusion, but my Note 3 show "GPS" while my Note 10.1 show "Location".
Anyho, both devices have both GPS hardware and location-based network turned ON. Correct me if I am wrong, but if the device couldn't find GPS signal, it'll just revert to the location-based network. I think it doesn't make sense for the OS to use both at the same time as it will create a conflict on the accuracy of the location.
For the Note 3, it use stock ROM but rooted. It is on 4.3 and I have installed many apps.
For the Note 10.1, it use stock ROM and not rooted. It is on 4.4.2 and brand new, no 3rd party apps installed at all. I only setup Google account for email and calendar. No Google Now. Disabled bloatware from "Application Manager".
With the Note 10.1, something must have changed in 4.4.2. I will try to turn off GPS and location-based network completely and see what happen.

High accuracy uses both gps and wifi

I had the same problem with my Note 10.1 2014. Send it to Samsung for repair and they said it was the battery. Got it yesterday and after a full night to charge to 100% it only gave me 3 hours and 40 min of use. I used to have 8 to 10 h of use. It's Kit Kat, I'm sure. It's really crap. I used to love it before the update now I just hate it.

Wait, did you have the awake problem like mine? Also, did you meant 8 hours of screen on time?
As shown in my first post, I have 1.5 hours of screen on time and with the awake problem, I still have 68% left.

Yup, that's what I have. I am going to turn off GPS and Wifi-based location completely (from the dropdown menu, press the "Location" button) and see what happen. The tablet is charging now, but I will post update soon.

Did you do a factory reset after updating?
I know Samsung says it's not neccessary, but it still is highly recommended.
I too have stock 4.4.2 (factory reset, than rooted) and nothing else, didn't even bother to debloat it yet. I will play around with it today and report back.
Edit: surfing drains about 10% in 1 hour. Have not tried gaming yet.

I thought i'd give some of my personal experience:
I just installed a game called DeProfundis Requiem (a 3D, diablo 2 like game) and had some serious battery draining at first.
The other day I played maybe 1 hour and my battery dropped to 15%. 3 minutes later (or so) it dropped to 5%... I rebooted, and the battery showed around 29%. Tried to play again and that only lasted 5 minutes and then the tablet turned off.
Since then, things seem to have stabilized. I now can play that game for over 2-3 hours, with quite a bit of battery left. What I did notice is that if the tablet got hot (on the right back side), then the battery drains quite fast. In the contrary if I'm indoors with AC, the battery seem to last much longer.
I think this has to do with the tablet overheating and therefore draining the battery faster. Maybe something you can try is that as soon as the device start feeling a bit hot, turn it off for 10mn, and try again.
I hope this can be useful to some of you.

Just a quick update:
I hard reset my tablet (remember, it's brand new), which already have 4.4.2. Configured Google account, disabled bloatware, turned off GPS, turned ON Wifi and installed Zinio for a test.
Left the tablet overnight, use it very slightly. Check out the battery drain caused by Android OS... It's definitely some sort of bloatware or 4.4.2...

Not familiar with the battery app you've got, pretty confusing bunch of numbers there! Better battery stats is one of the best battery monitoring apps and gives you concise wake lock info.....it may require root now though, can't remember.
Your Android OS is always going to consume a higher percentage of your battery if you don't actually use the tablet. 86% after 12 hrs off the juice ain't to bad?

It's GSAM Battery, quote popular in XDA. BBS require root, which I dont have yet.
Since this tablet is brand new out of the box, I conclude it's Android OS / one of Samsung bloatware causing the drain. Not much I can do til I root the tablet, but I am waiting for one that is not tripping KNOX.

Oreo battery feedback

Hello,
I dont really found centralized information about Oreo and feedbacks regarding battery life.
So please, people from Korea and North America, can you provide some feedback about Oreo update, especially about the battery life ?
I heard some negative opinion from this video : https://www.youtube.com/watch?v=m5hH0TQY6Jg
Before he was at 5-6h SoT, after update 3-4h
Thanks !

It was entirely predictable and expected that there would be no improvement in battery life or performance with Oreo despite all the anticipation.
I have literally NEVER seen a major operating system upgrade actually speed up performance of identical apps on the same device. Sometimes there might be a non-significant decline, but never an improvement.
Each Android upgrade promises some new trick to improve battery life like wakelocks etc, but it's only theoretical and perhaps applies only to brand new hardware.
Otherwise the progressive process of bloating in updated apps and system software use more power and more resources which more than compensate for the supposed improvements in efficiency
I think the few reports that have mentioned improvement are just the random variation that people get, even with Nougat, or even day to day on the same device.
Sometimes I get 1% standby drain per hour and sometimes 3% with no change in use or settings. I have found no consistent way to control this, including trying all of the tips mentioned (except for wiping my phone and starting from scratch).
So far the video reviews that I have seen of Oreo on the G6 are pointedly unexciting and confirm my predictions. As far as I am concerned the only reason to update is for the security patches. I am hesitant to update given that going backwards is difficult on a unrooted device.

maybe some little improvements are made, sure, nothing big to say its a major update, NO!
is almost only a Android version bump and a security patch. PERIOD...
The features this new version introduced is low and people who update the phone dont will see a big change, i already see some videos of update in youtube and didnt see too much difference.
Of course is a good thing LG doing it but isnt night and day,is more like some hours of difference.
Lets see with time to time the Doze mode and power savings features step in and see some change in battery life, i trust LG make something to improve it, again nothing special but for me that already make a difference.

2 remarks :
From my experience, I never saw an android update improve battery life too. But that was a long time ago, with "cheap" phones (expect nexus 4, so disappointed). But recently, a friend bought a Nokia 8, and after the Oreo update, the battery has become so amazing, I was really really suprised and so jealous! So now I still have a little hope ...
However concerning standby drain, for me it's pretty ok. In airplane mode lost 0 or 1% for all night, and with data or wifi, it stays "normal".

You guys have something else going on.like the first post said it depends on day to day and other factors like many apps running in back ground.My phone and battery have 0 issues.on full charge it stays at 100 for about 10min on heavy internet use and then drops about 2percent per hour.I only charge my phone every 3 days.I also found phone much faster after oreo and less studder.I suppose because part of the update is to have less apps running in background.I wouldnt really listen to some users because the change log for oreo is huge.Soooooo many changes under the hood.people should read the change log before giving false facts(and they are false)Always gonna have some dude complaing about something

Did you make some improvements like disabling logs and reducing resolution ? Any reset after oreo ?

I disabled event logs yes.kept screen on large size and no resolution change.Yes I did a factory reset immediately after.I think alot of people are having issues with battery because they dont calibrate it first when new out of the box.As a rule of thumb no matter what electronics i buy i always charge to 100 percent and literally let it drain to 0 percent then full chage again.Do this step twice in a row and i can pretty much guarantee you wont have issues with battery that are out of the ordinary.LOVE MY G6

I just got the upgrade on my g6+ batterie Went bad. .....I started to analyse battery usage and i found that chrome browser was one of the cause ..So i change it for Microsoft edge browser. ..now my battery is draining less. ....So i hope that did the trick. .......and i also cancel all other apps that i did not use

Almost 6h of SoT with heavy gaming. Doesn't sound bad to me. ?View attachment 4508939View attachment 4508940

It's strange that there is so much different experiences between people. This is not reassuring!

There are people that mainly use the phone under a wifi connection, and others that use it under a mobile network, this is just an example to give you an idea of why there is much difference between users

Y kllua but people are complaining regardless of wifi or mobile network. My package includes 6gb of network per month every month i spend 4gb etc...
And lots of people i see have bluetooth, nfc ( if they even thats in or what it even is. ) and then comes some1 like you and says ooo wifi on. What im gonna use at home ? Data ? To consump battery and empty my month data, and what im gonna use on streets, work, free time outside house etc. Mobile fking data. You think wifi is all around us

Well, my G6's battery sucks because at work the phone switches every couple of minutes to all the networks, and so I'm not able to reach home after 9-10 hours with 1-2 of SOT without charging a 20-30% during lunch, besides in weekends where I'm almost everyday under a wifi connection I easily reach 4-5 hours of SOT with gaming in a full day usage.
Also yes, there are many other parameters, like BT, NFC, GPS, Apps ecc...

So finally got Oreo thanks to LG Brigde.
The battery stock app seems really... broken ? Please see screenshots.
The message says : "2 days ago , 1h27min left the conversation."
PS : I made a factory reset after the oreo update.

Mine has actually improved! I'm getting like 30 minutes more (the improvement came after I drained the battery almost completely and charged it back like 3 times and after a factory reset). Not much but I can't complain. I'm actually happy for the improvements in fast charge speed, it's even faster now.

Third day with Oreo now.
Battery life is great, at least as good as before. I have 3.5h of screen on time right now and I'm at 43% battery at the end of a full work day with traveling etc.
And that's with Nova Launcher, Gesture Control [root], Always on Display and Pixel live wallpaper enabled.
Very happy with the G6 at the moment. Of course battery life always depends on your personal use and different phones provide better battery life for different people... G6 seems to work well for me and definitely better than the Huawei P9 I had before.
For people with battery life issues I suggest this: Battery life guide (I keep resolution at max because it messes with AOD and camera)
and also if you don't use google voice assistant try disabling the google app and use the chrome search widget instead. And keep location services on battery saving mode if you don't need GPS all the time.

Tab S5e horrible standby battery drain

Last week I have purchased a brand new S5e, and overall I am pretty happy with it, outside of one big problem: the damned thing loses like 30-40% of full battery charge per day while sitting in my desk drawer, doing absolutely nothing. This is, frankly, unacceptable. My two-year old Galaxy Tab A loses 2% per day when idle, so I would kinda expect similar idle drain from the new device as well, given they have similar-sized battery (7040 mAh in S5e vs 7300 in Tab A).
I have tried:
Uninstalling unused bloatware via ADB pm uninstall
Turning off data and wifi
Turning location off
Restarting the thing
"Sleeping" of all the apps via Samsung's battery save features
Factory resetting the tablet and repeating the above with no extra apps installed
Tried the "Extreme battery saving" feature, but frankly, that leaves the tablet in absolutely unusable state because it limits you to like 5 built-in apps and portrait mode. Who the f uses their 10" tablet in portrait mode?!
Currently trying Airplane mode, will see how that goes, but I'm not keeping my hopes up at this point. -- Update: Airplane mode seems to have satiated its hunger for battery, but that's not really an option to keep on at all times. Any other ideas?
I'm frankly running out of options here. I bought this for xmas and it's, tbh, unusable in this state. It does have the latest software update from Samsung (October 1st, 2019).
I've tried running BBS to shed more light on what's going on, and while it's showing the device is spending nearly 50% of the idle time in "Awake (screen off)" state (compared to 2-4% on my tablet and phone), but neither Kernel nor Partial wakelocks show anything egregious. And normal battery stats are about as useless as you'd expect, too.
Currently considering taking it back and asking for a return or RMA, but figured I'd ask here first, maybe one of y'all has encountered the issue and by chance knows what's the problem and how to fix it.

You need to take an idle log with BBS and post in the BBS thread asking for some analysis.

Remind me, how do I do that?

Naptime by Francisco Franco will turn off Wifi / Data / GPS when the screen is off, and turn it back on when the screen is turn back on. Works best on Rooted devices though.
I'm using Lineage 16 on my Tab S5e, I generally get somewhere between 7-8 hours of SOT, and go 5-7 days between charges. I use Naptime on all my tablets have for a long time. Found it doesn't work as well on cell phones. I haven't paid attention to what my idle drain is, but overall my battery performance has been excellent with Lineage.

The BBS thread has all you need. Read it there...

I have figured it out.
Turns out, the tablet has some issues with the provider's sim card and plan. I got internet-only plan and it does not allow for neither outgoing nor incoming phone calls. And my other tablet has a normal calls+data plan. When I swapped cards between the two tablets the drain issues also swapped! Except the older one wasn't draining nearly as fast, but still noticeably enough. While new one only lost 1% overnight.
So looks like I will be staying with my old plan, maybe upgrade it a bit. Oh well, no big loss, but mystery solved.
