Got my LTE upgrade done on my Xoom and now the battery is a joke. I went into settings and disabled the LTE connection, so that now 3g is only used. I also turn wifi on when at home. Currently my Xoom is draining 4ish% per hour while in standby. That means this damn thing won't last a day just sitting there, locked, with no screen on. In Honeycomb 3.0 and 3.1 I could get a days of use with 4-5 hours of screen on time and about 22-26 hours of total unplugged time. Now, under 3.2.2 my battery is totally dead after 18 hours of unplugged time with around 1-1.5 hours of screen use. This is virtually unuseable for taking notes in graduate school after work, when being close to an outlet is impossible.
Any ideas as to what's going on? Tried using Watch Dog and System Panel to see if any apps were going nuts with random CPU usage or RAM usage and everything seems to be in-check in terms of system resource usage. Considering I have 4g totally turned off and wifi enabled when I'm in range of wifi (most of the day) I don't have a clue where this power drain is coming from. Any assistance is highly appreciated given how much I rely on my Xoom for day-to-day use. 3.2.2 seems to have killed it for me.
Please help! Will try any suggestions.
Thanks.

Have you tried disabling mobile data entirely? When I'm in wifi, I disable the cellular connection but haven't performed any in-depth trials on battery life.
"Settings" > "Wireless & networks" > "Mobile networks" > deselect "Data enabled"
Its not just you, mine is the same way it sucks big time. There really isn't anything that I've found to fix it.
I loved how I used to be able more than a day out of a charge...
Anybody have any ideas? Maybe undervolt kernel???

I just received my zoom Lte upgrade and haven't had any battery issues.

I haven't but this isn't feasable. I use mobile internet for everything and even take notes and such on Google docs. Even though I'm near wifi for most of a given day, I shouldn't be bothered by manually turning mobile data on and off just to have power- mobile data should be mostly killed when wifi is active. That's how this Xoom worked before. A tablet without internet is nothing more than a paperweight to me. 2 classmates with LTE upgraded Xooms are having identical problems. No fixes found yet. Any other suggestions? This battery life is really, REALLY bad.
Tried going a factory reset and battery life is the same, horrid short, running nothing but stock apps.
Any other suggestions?

How long ago did you receive it? The degraded battery seems to have started shortly after the first initial charge after the LTE install.

Same problem here, but I have the mobile network completely turned off and it still does this! Even with the switch to CDMA only!
I will keep reading this thread (only read the about half the posts before posting) so hopefully a solution will show up. But you're not alone in the horrible battery life post LTE upgrade!
I've had my Xoom back since last Wed.
No higher battery drain than previously.
I'm on wifi 90% of the time in home and office.
Yesterday I was all over north San Diego county using 4g. Got home with 60% charge which is about the same as for a prior trip with 3g.
Put your xoom back the way it was. The new hardware sucks the battery a little more. Buy a thunderbolt and then say the xoom battery life sucks. Never charged it during the day before the upgrade. Oh well, that's the price if 4g.

Download Auto Airplane Mode by DON from the market. It will help BIG TIME!! It does just what the title states, it puts the Xoom into airplane mode automatically as soon as the screen goes off. When you turn the screen back it, the data comes right back in 3 -4 seconds and you're good to go!
Also, you don't have to uncheck any settings or turn 4G off.
Update: Mobile data completely turned off, on wifi only with Xoom sitting about 4 feet from router all morning, so wifi signal was strong. This is the first time I've used the device today. Unplugged at 330am my time, its now 130pm. Device battery is at 60%. 10 hours and 40% of battery gone. That's with mobile data 100% disabled, wifi only- can't even get the Xoom to standby for a full day now. At this current drain rate, it would go from 100% to 0% in one day with no mobile data usage, no screen on time and no usage other than syncing Gmail every 2 hours.
Brother who commented above: Thunderbolt will standby for a full day with no screen on time on wifi only and it has under 1/3 the Xooms battery capacity. I should know- my wife has one and it now outlasts my Xoom. That should not be the case.
From my understanding the Xoom has two 3225ish batteries set up in a sequence. My battery life actually seems to be about half of what it was before. Is it possible that one of the two was disconnected during the LTE radio installation and not properly reconnected? Wasn't sure of the details of how the batteries were set up, but if the Xoom could function with the second battery not working, seems like that would precisely half battery life. Anyone familiar with exactly what had to be done internally to upgrade the radio? Looking at the ifixit teardown of the Xoom, the batteries cover the whole backside- looks impossible to do any internal work on this thing without removing them. Any thoughts?
Cheers,
Landon

Same here. Can't get a full day out of it. Hope a fix will be comming up.
Thunderbolt got the he-man battery and modded my otter box to fit. The xoom battery has entered the battery hog realm after the lte radio. As far as I can tell the radio is cdma/lte together. And it uses power even if wifi is on and data off. It's what I would call big brother watcher. Even if your not connected the radio is txing and rxing something. You know it's lojacked!

Interestingly enough, removing the LTE SIM card and using wifi only made no improvement to battery life. I'm assuming the new radio is running at 100% all the time without throttling down, even if absolutely no connection exists or there is a string of faulty battery reinstalls in which only one battery is providing power. That might explain why some people seem to have greater battery issues than others.

im glad im not the only one with this problem! its pathetic! im taking my charging cable from my dock with me to work so ill have at least some battery life when i take the train home in the evenings
i to am glad that I'm not alone with this either. I use to charge mine every 4 days with no wifi on and almost no use. Now I get about a day with no use. I mainly use it for web searching and dungeon defenders when I'm home. Horrid battery life for doing nothing. Luckly I mainly only use it at home and am almost always on the dock I got from motor from the upgrade. I use about 4% an hour also with nothing on. Mine is completely stock with no root.
Yahoo mine is stock with absolutely no root or other mods. I guess they knew about the pissy battery life and that's why they gave a free dock. Lol. Still trying to find exactly what's killing the battery. LTE does drain a lot of juice but as I've stated before my wife has a Thunderbolt and per mW of battery power, the thunderbolt is more efficient and that's not saying much. It can standby for over a day with no use fine and it has roughly a little less than 1/3 the Xoom battery capacity. Something isn't right. Its not supposed to be this bad. Anyone filed a complaint/tech request with moto/Verizon? I think its something that we should all do and report what they say here. I have a feeling more and more people are gonna have this issue if they do the upgrade. Maybe if enough of us make some noise, something will be done.

Maybe it's not the radio.
3.2.2 may have some kind of interaction with something you guys were running that's causing wake locks to get stuck
Did you look at Settings:About Tablet: Battery Use ?
(tap on the histogram at the top for another, see if the time spent awake is solid or different from screen on)
I tested this on mine, with the mobile data disabled and lost about 1% battery every hour, this is on par with the performance I had pre-upgrade.
Rooted, stock kernel
I realize it does not help you but you might look somewhere other than the wireless radio for the problem. I unplugged my upgraded Xoom yesterday morning around 8:30 AM. It is now 8:20 AM and my battery is at 66%. I was on 4G for about 2-3 hours yesterday, the rest of the time on wifi. I check and respond to my mail on the Xoom so it saw some use yesterday, though not as much as I normally do.
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.

Just to clarify when you say GPS, do you mean location services? Thought you meant the GPS was actually active.
Edit: location services work a bit differently going from jellybean to kitKat

Have you got the same apps running on both devices? And same location reporting settings for any apps that use it?
How many charges have you been through? Some times when installing new ROMs Android OS does come up as using a lot of battery, not sure if that applies to a fresh stock tablet though

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.

Go into location services/mode in settings on your note 2014.
You'll see there are three options.

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.
Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?
battery life
I've had my phone off the charger for less than one hour and I'm already down to 90%. There's definitely something wrong because stock lollipop unroot was giving me much better battery life and performance.
Mine lasts about a day and tbh for a device with the specs of a low end PC with a HD display and constant internet connection thats about what id expect

When your battery lasts less than HALF the time of what it used to all because of one update, something is seriously wrong.

well mine lasts a day now and it did then. so either you need to factory wipe, or you need to look at apps you've installed thats not quite optimised for lollipop
Yup, factory reset solves battery drain after LP update, I was up to day 3 without charging this morning with still 18% battery left, but had to charge up as I was going out, reckon it would have lasted the rest of the day though

Got a reply off the Samsung Twitter team to do this, so now going to give it a go. Hopefully it'll sort it because the drain is driving me nuts

Factory reset will lose root more than likely, almost certainly
It happened with me but after 2 days everything settled and battery lasts at least 12 hours but still less than kitkat.
I installed the update to lollipop..... After that indeed a horrible battery life. So I installed lollipop again using kies software......
Had same experience wipe and reload greatly helped. Supposed to be addressed in 5.1.
To add yet another subjective and anecdotal experience with the new S5 Lollipop update (on Verizon, in my case), I was seeing constant Wi-Fi disconnects (~5/minute) AND battery-life that went from ~15 hours to < 5 hours, until I turned off the "Smart Network Switch". Seems all the network switching was killing the battery as well. Did a FDR and it made no difference. As long as that feature is turned on, my Wi-Fi drops constantly and the phone heats up and the battery dies in a few hours, even without use.
Would be nice to know what I'm missing now that my phone is, apparently, using the Dumb Network Switch instead.

All you're missing now the phone is using the dumb network switch, is bad battery life, constant wifi disconnects, and headaches
I turned it off a while ago, and so have many more people I read about each day - it's supposed to keep you connected to the strongest signal, but in reality, it does the opposite, plus most people only have 1 wifi connection, so it's not necessary to smart switch - and even without it enabled, it will still connect to Data when it goes out of range of WiFi, so that switch is completely pointless to start with

Yeah, I kind of figured that. Sadly, I do have two wireless-access-points in my home to handle range-issues. I had not considered that this "feature" would have a bearing on the switching between them. I did test with one of them turned off, so I could eliminate that as a possible cause before I knew about this broken functionality, and it didn't matter of course.
Does it not seem a bit odd that testing didn't uncover that a Lollipop Galaxy S5, with Smart Network turned on, would kill the battery and render the Wi-Fi inoperable?

Yeah, I kind of figured that. Sadly, I do have two wireless-access-points in my home to handle range-issues. I had not considered that this "feature" would have a bearing on the switching between them. I did test with one of them turned off, so I could eliminate that as a possible cause before I knew about this broken functionality, and it didn't matter of course.
Does it not seem a bit odd that testing didn't uncover that a Lollipop Galaxy S5, with Smart Network turned on, would kill the battery and render the Wi-Fi inoperable?
Oh well.

You could set up your two APs with the same SSID / Encryption key and have the phone switch seamlessly between them without smart network switch enabled
Some info on how to achieve this here

But yea, it seems that there are quite a few overlooked bugs with lollipop, 5.0.2 and 5.1 apparently address a lot of them, but when we get that update is anyones guess

Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?

Wrong section, all questions go in Q&A. Not general.
please note that there are some apps are working without permission like google music i think ,
I recommend you to stay in KitKat until Samsung Lollipop 5.1 firmware arrives. At the moment I'm using XtreStoLite ROM with Toiiki kernel and I'm getting am awesome battery life, about 8 hours of screen on, cheers.
My S5 is G900H and I have the same problem. I did not like lollypop
I just got my phone a couple of days ago, and seem to have some insane battery drain. I leave it on overnight and in the morning it seems to be down to about 10%.
Is anyone else seeing this sort of issue?
Here are some screenshots:
While the battery is OK but not stellar, I notice you have Wi-Fi on? Turning that off overnight helps immensely.

I had a UK axon 7 A2017G that would only last 4 hours from full charge with everything switched off except mobile. In the end I had to return it to the supplier. Sadly they don't have any replacement phones. I received it on 29th July.

My second unit arrives today so if battery is poor I have 30 days to return. That should be more than enough time to evaluate.

I have a Galaxy S4 running 6.0.1 from JDCTeam that gives me way better battery life with WiFi turned on all night, and runs way more apps than this phone (plus, the battery is just 1850mah). I suspect that there might be a lot more going on under the covers here with respect to hidden services. I am not happy with the fact that the battery usage stats are hidden.
Should I root and try to use betterbatterystats to figure out the real problem? or maybe just assume its defective and ask for a replacement?
I think you need to turn this off too. Otherwise, it will keep searching for wifi even you turn the wifi off.
I'm having no battery drain issues. I have the Grey one.
I have turned off mipop and voice print. Dunno if that could be the culprit.
Turning off Smart Power Save increased my battery life
I have the same issue... 10 to 15 % drain over night other than that the phone it's amazing... When I got the phone before I even turn it on I got in recovery an did like 3 times a factory reset ... I'm gonna keep the phone for 2 more weeks if the drain continue I'm sending it back to newegg ?

No bad drain here, I only dropped 2% overnight (11pm -7am)....Wifi was on and I received several emails and a few text that were waiting when I woke up.
yeah the battery was massively overrated pre-purchase
Thanks dougm0 and Barsky ... I turned off Smart Power Save, MiPop and Voice Print. I also made sure that the location section was only using GPS (not wifi+bluetooth), and it all made a difference. I still feel like I can squeeze out a lot more performance here. My deep sleep numbers in better battery stats has improved, but it's still not where I want it to be. As I make more tweaks and get better battery life, I will post screenshots and settings tomorrow (maybe it might help someone else).

Something I always notice that you might also want to take into account. When you get a new phone you are not using it as you will regularly be using it after the new period wears off. You are probably testing all the different aspect of the phone and just plain messing around in ways you do more of when the device is new. I always get horrible battery time in a new phone
No issue with battery drain - left my phone at 100% overnight with WIFI ON, in morning it was at 97%. I think I will take it as 3% drain over 8 hours.
You most likely have an app that's causing wake lock issues. It's a common problem on any phone.

My battery is amazing on this device.
I Don't mean to rub it in anyone's face that have these issues. Must be an app that's causing it.
Coming from Note 4 and Moto X Pure. This is twice better. I don't read screen on time on this device because it doesn't show it. I don't even need those stats. After 16 hours of the charger with same use I get home with 40%+.
My Note and X Pure were dead by then or have been connected to a charger by that time.
Hope y'all figure it out.
Battery life on my phone is not that great either. It's not horrible but I expected better. I think it drains 3% in 4 hours with wifi and sync on. I did turn off all the scanning and battery saving feature.
I recently noticed the battery on my phone was just 3140 mAh instead of 3250 mAh like on the website says it should for the US model. Can you please confirm what capacity your battery has?

It's 3250 for the US model, but there is an issue with the partition where it still shows the original 3140 mAh instead. It has been notified to ZTE and they said that it will be fixed in the next update.

ahhh gotcha. I almost wanted to return it if they lied to us. Thanks for the response buddy.
I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.
Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.
Still on 6.0.1 & Android System is my #1 battery drainer.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.
If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.
Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.
Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.
So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.
