New update: i discovered by enabling and re-disabling wifi calling and VoLTE "cell standby" quit increasing. For some reason the update must have bugged it but that resolved the issue.

I however am still experiencing worse battery life than before the update. 1 hr left at work and ive barely used my phone at all today, 36% left, it's been 8 hours off the charger. Normally id expect to be around 40-65% right now with how little ive used it. (depending on what combination of disabled stuff im trying)

Further more my friend with an att s6 charged his phone saturday n had it off charge since. Didnt use it all weekend until today at work with 20 min charge in car.... Been on bluetooth headset n listening to music/youtube all day. Hes currently at 39%

every day that i compare battery life with him pisses me off more and more. He's probably getting 2x as much battery life as me, without any tweaks or anything. just pure stock.
[T-Mobile Samsung Galaxy S6] Dr. Fed:
Well at least you can apply the old "fix" again (no Wifi-calling or VoLTE). I hear you though; battery life is worse since the update. I installed Package Disabler Pro and removed just one program: T Mobile My Account. Will this make any difference? I don't know but I'll report back if it does. I figure if other variants get better battery life, we should make our s6 similar. That T Mobile My Account app was the first obvious choice to get rid of.
[T-Mobile Samsung Galaxy S6] davwman:
Battery doing excellent for me since latest update. After installing latest fw i enabled and disabled volte and wifi calling which i dont use and average anywhere from 5-6 hours sot with alot of phone calls and pandora streaming, email sync set to push, browsing reddit, facebook via cmbrowser and of course xda. I keep bluetooth and nfc on all the time and wifi only at home. I didnt root yet because i want finger print scanner to work and android pay. I have used package disabler pro as well as galaxy button lights app set to keep capacitive keys off and couldnt be happier. Im getting better batery life than my heavily modded and rooted note 4. The gs6 is a beast of a phone and im not looking back.
[T-Mobile Samsung Galaxy S6] davwman:
This is where i sit right now
[T-Mobile Samsung Galaxy S6] twolfekc:
Not too shabby
[T-Mobile Samsung Galaxy S6] Dr. Fed:
What do you disable with the package disabled pro ?

What did you disable ?

Download the attached xml file from package disabler pro and use the import xml option. I also have all the knox stuff disabled. I believe the new version doesnt allow that and i am not updating the app because of that.
[T-Mobile Samsung Galaxy S6] rha_december:
My battery life has been fairly decent after the latest update + Package Disabler Pro.
[T-Mobile Samsung Galaxy S6] Dr. Fed:
Did using PDP solve the cell-standby battery drain, or did y'all just stay away from VoLTE and Wifi-calling?
[T-Mobile Samsung Galaxy S6] rha_december:
I disabled voLTE and wifi calling as well. I'm not getting near 5-6 hours like davwman, but still pretty decent.
[T-Mobile Samsung Galaxy S6] davwman:
Honestly pdp helped but disabling wifi calling and volte is the biggest factor. I was having the same problem with my lg g4
[T-Mobile Samsung Galaxy S6] mannequin:
just got this phone and it's annoying that cell stand by issue is still here.

so if we want to use voLTE there's no way around the drain at all?
[T-Mobile Samsung Galaxy S6] guaneet:
Not bad. 100% stock.

Everything enabled including nfc, WiFi calling and voLTE
[T-Mobile Samsung Galaxy S6] guaneet:
Rooted this time
[T-Mobile Samsung Galaxy S6] ThePagel:
Man, wish I could get that much sleep at night.
[T-Mobile Samsung Galaxy S6] aff219:
this is a joke right? there's no way you're able to idle for 8 hours on battery - with NFC/WIFI/LTE on - and maintain 100% battery life
[T-Mobile Samsung Galaxy S6] Dr. Fed:
Goes without saying, that screenie was bull-pies.
[T-Mobile Samsung Galaxy S6] guaneet:
I had data turned off that time with no wifi. Wanted to see if I would still get cell standby. I'll post some new ones tomorrow morning and try to achieve it with lte
[T-Mobile Samsung Galaxy S6] MeanBoss:
Why the hell I can't find volte, and WiFi call settings anywhere on my phone? BTW. It's Croatia Tmobile... Don't know does that mean anything :/
[T-Mobile Samsung Galaxy S6] Dr. Fed:
Maybe Wifi-calling and VoLTE are not available on your variant. This is for SM-G920T. You are probably in the wrong forum.
[T-Mobile Samsung Galaxy S6] MeanBoss:
You're probably right... I have G920F... :(

Is my battery good?
[T-Mobile Samsung Galaxy S6] altimax98:
I'm thinking something may have bugged out in the OTA, maybe doing a factory reset fixes it after getting the OTA
[T-Mobile Samsung Galaxy S6] Calnyx:
This is what fixed it for me, so I also suspect the OTA caused some issues to appear.
[T-Mobile Samsung Galaxy S6] laureanop:
Got the phone a few hours ago and so far so good, WiFi off and took the OTA right away. Already installed all my social media apps and all my email accounts are syncing.
[T-Mobile Samsung Galaxy S6] laureanop:
On pace for 5-6 hours SOT which is very reasonable
[T-Mobile Samsung Galaxy S6] greyhulk:
Weird that your screen time is at the top. I have 3.5 hrs of screen time so far and android system, android is, and cell standby are all above screen time in my battery stats.
[T-Mobile Samsung Galaxy S6] laureanop:
With all my past Samsung phones that has always been my typical order with screen sometimes being 2 or 3
[T-Mobile Samsung Galaxy S6] greyhulk:
Yeah. It seems like the newer amoled screens are super efficient. I remember when screen was always the top battery draw.

Sent from my SM-G920T
[T-Mobile Samsung Galaxy S6] whittikins:
Just to clarify, you're just referring to the factory reset option in settings right? Just making sure you don't mean connecting to a pc and flashing the factory image or something.

Also, once you have reset it, can wifi, wifi calling, and volte be used without causing the drain?

Thanks
[T-Mobile Samsung Galaxy S6] laureanop:
Wow what a major bug this Wi-Fi/cell standby battery drain is!!!

My phone did awesome the whole night and I was on pace to 6+ SOT. Then I got home and turned on Wi-Fi to transfer some pictures and in a matter of an hour Cell Standby went from 1 to 9% !!!!! As soon as I turned off Wi-Fi the drain disappeared!!!

It's not an issue for me cause I have unlimited data and don't need Wi-Fi, but it's a MAJOR bug that hopefully it gets taken care of soon!!
[T-Mobile Samsung Galaxy S6] twoeleven99:
Turned off WiFi call and volte and I noticed the difference immediately.
[T-Mobile Samsung Galaxy S6] NJGSII:
Ota's sometimes do some wacky things. Gonna try a factory reset myself to see if that does anything. Why I always flashed RUU's or waited till roms with new bases were posted here when I had HTC devices.
[T-Mobile Samsung Galaxy S6] jzero88:
So this is blowing my mind. I had a 1% battery drop over night. Basically 7 hours, this is pretty amazing.
[T-Mobile Samsung Galaxy S6] guyd:
Can you provide us with any tips you have done to your device to achieve this?

Did you take the OTA?

Did you factory reset after taking the OTA?

Did you root?

Did you disable any apps?

Did you disable VoLTE or WiFi calling?

Please share the details. Thanks!
[T-Mobile Samsung Galaxy S6] jzero88:
Yes.

No.

No.

Yes, Facebook, hangouts, etc. Can't provide with a full list sorry.

Yes.

I have battery saving mode turned on but won't activate till I hit 20%.

I did close all apps before putting it down for the night. WiFi was on all night too.
[T-Mobile Samsung Galaxy S6] dhaliwal925:
Hi All,

Like many of you, I did a factory reset as well. It seems to have helped, but I am still testing it out to see what the issue is. So this is what I have done so far:

Wiped, but did not restore. I set it up as a new device this time.

Set up Gmail and it asked me to install "Google Play Services" - this did not happen initially and I had usage from Google Services, now they are nonexistent.

Wifi calling is on, but VoLTE is off - for those that don't know turning VoLTE dramatically reduces the number of dropped calls.

Didn't install any extra apps, but set up WhatsApp.

Phone has been on WiFi, wanted to test the drain without any syncing.

Alright so the phone is at 80% with about 6 hours of usage and 1 hour of screen on time - mostly WhatsApp and web browsing. Cell standby is the highest user followed by the Android OS - freaking screen didn't even show up until I dipped past 85% and only accounts for 1%. This tells me that the screen is either highly efficient or not reporting correctly.

TL;DR Factory reset helped, cell standby still an issue, and the screen might actually be really efficient!
[T-Mobile Samsung Galaxy S6] PunishedSnake:
Chrome stalls when trying to load that link. What's the app called
[T-Mobile Samsung Galaxy S6] ViciousDiarrhea:
App Ops.
[T-Mobile Samsung Galaxy S6] NJGSII:
So I turned off volte and WiFi calling as well as disabling some apps and standby drain has home way down. I'll have numbers later.
[T-Mobile Samsung Galaxy S6] ChristianBale:
Turning WiFi off, charging the phone completely, and restarting fixed the issue for me. I'm also going to test VoLTE to see if it works.
[T-Mobile Samsung Galaxy S6] bubblebuddyi:
Turning off VOLTE definitely helped me out, finally have a temporary fix
[T-Mobile Samsung Galaxy S6] altimax98:
I went ahead and updated the OP with disabling WiFi calling and VoLTE fixing the issue based on responses in this thread
[T-Mobile Samsung Galaxy S6] poweroutlet:
I have this issue as well. Anyone else have it?
[T-Mobile Samsung Galaxy S6] km8j:
No flash issue for me. Battery disappearing like is going out of style. Before this thread, I removed bloat, used greenify and disabled wake on a lot of app ops thing to no avail. Been off the charger for 90 minutes and total screen time of 35 minutes and down to 69% which is unacceptable by every standard. I just turned off Wi-Fi calling (although before this I had cellular preferred) and turned off volte (which sucks not to have) and will see if this helps. I also have nothing in gsam that indicates a major drain. Does anyone feel like their phone gets hotter than it shpuld, especially with this new processor?
[T-Mobile Samsung Galaxy S6] greyhulk:
Have you tried a factory reset? That fixed the issue for a lot of us. Seems the OTA may have messed something up.
[T-Mobile Samsung Galaxy S6] km8j:
Yes I had to because of a problem during root lol. I can try it again though. Did you do it through recovery or the in OS menu? I guess I'm confused on if the reset fixed it or turning off volte/WiFi calling?
[T-Mobile Samsung Galaxy S6] greyhulk:
I just did it through the OS menu. Fixed the major drain I was having.
[T-Mobile Samsung Galaxy S6] wund3rground:
Hmmm... Still no cell standby for me and I have VoLTE on. Perhaps VoLTE isn't active in some of your markets yet.
[T-Mobile Samsung Galaxy S6] km8j:
Decent theory as volte is in my market
[T-Mobile Samsung Galaxy S6] ChristianBale:
Any word on an OTA update?
[T-Mobile Samsung Galaxy S6] greyhulk:
I have news, but I'll only tell you if you use your Batman voice.

Sent from my SM-G920T
[T-Mobile Samsung Galaxy S6] ChristianBale:
(Batman Voice): WHERE'S THE OTA? WHERE IS IT? WHERE'S THE OTA?
[T-Mobile Samsung Galaxy S6] greyhulk:
Haha. Dammit. I didn't think you'd call my bluff. I don't really have news, but that was awesome.
[T-Mobile Samsung Galaxy S6] dhaliwal925:
Are you using WiFi calling at all?

I turned my WiFi calling off and I finally have my screen usage above cell standby! And it's funny I just remembered this but on my Xperia Z3 when wifi calling was enabled it completely disconnected from the cell tower, used to show a little red 'x' by the signal bars. It could be very likely that there is a bug that is contradicting with the state of the phone while in WiFi calling mode and it keeps searching for signal it doesn't need to...just a theory I am not that technical.
[T-Mobile Samsung Galaxy S6] bubblebuddyi:
Yeah my cell doesn't turn off with WiFi enabled, I thought that was the whole purpose.
[T-Mobile Samsung Galaxy S6] wund3rground:
No, I have WiFi calling disabled. For what it's worth, even before I disabled it I still wasn't seeing cell standby show up.
[T-Mobile Samsung Galaxy S6] ChristianBale:
The Z3 previously hasn't supported VoLTE so it has turned its radio off while on WiFi calling. The S6 however does support VoLTE so that if you are in a call and walk away from WiFi your call will be transferred to the cell radio and not be dropped.
[T-Mobile Samsung Galaxy S6] altimax98:
After disabling WiFi Calling and VoLTE has anyone had to turn WiFi Scanning off and/or turn WiFi off altogether to stop the drain?
[T-Mobile Samsung Galaxy S6] se1000:
nevermind
[T-Mobile Samsung Galaxy S6] NJGSII:
So there definitely has to be something up with WiFi being on that's keeping the device awake. Had the setting that keeps it always scanning for location purposes off, WiFi calling disabled, and VoLTE disabled and still got the results that are in the attached images. Notice how I'm having no issues with location due to not using Google Now. Gonna change the setting to keep WiFi on only when plugged in to see if that helps. Will post those results.
[T-Mobile Samsung Galaxy S6] easyc:
Factory reset fixed my battery drain while idle. I think it also fixed my flash diode issue too (was dimly lit at all times).

I wonder if the two are related....
[T-Mobile Samsung Galaxy S6] altimax98:
I doubt it as I do not have the diode issue but did have the Cellular Standby drain before I fixed it.
[T-Mobile Samsung Galaxy S6] KevinNuhWin:
I just turned off wifi calling and VoLTE. I was wondering am I still a little high on cell standby or is this good?
[T-Mobile Samsung Galaxy S6] dhaliwal925:
From my experience turning WiFi and VoLTE off, and then restarting the phone has resulted the Cell Standby not even reporting in the Battery Usage!

That and turning off Location has dramatically reduced the drain - on the other hand now I can't understand why Google Play Service is so high up. I will put up some pics with my results.
[T-Mobile Samsung Galaxy S6] NJGSII:
So my phone is not entering deep sleep and WiFi calling and VOLTE is disabled. Looked under BBS and saw this wake lock at the top : 13930000.decon_fb. What is that. I don't not have Facebook on the phone either. Maybe deleted something that I shouldn't have?
[T-Mobile Samsung Galaxy S6] altimax98:
Your not the only one. Mine was fine yesterday and today it is showing the same thing
[T-Mobile Samsung Galaxy S6] NJGSII:
Yea I'm not sure what's going on. Whenever I had an issue like this before I was able to pinpoint the issue pretty easily. Now not so much.
[T-Mobile Samsung Galaxy S6] greyhulk:
My battery issues are back. Losing about 8%/hr with no use at all. Mediaserver and Google App seem to be the main culprits. I disabled wake for Play Services and Search and cleared Media storage. Same issue even after a reboot.
[T-Mobile Samsung Galaxy S6] NJGSII:
OK I just figured that wakelock out. It has something to do with the screen being on. Notice it's the same as screen on time in duration and the count is how many times the screen has been turned on. So something else is causing the phone to stay awake. Might have to do another factory reset to get to the bottom of this but I really don't want to.
[T-Mobile Samsung Galaxy S6] bubblebuddyi:
Is it the edge features? Like information stream and etc.
[T-Mobile Samsung Galaxy S6] NJGSII:
No as I have a regular S6
[T-Mobile Samsung Galaxy S6] NJGSII:
Ok so I figured out what was keeping my S6 awake and it's embarrassing I didn't think of this. It was Spotify's connect feature. I have it on my S6 and my Nexus 5 that I use around my house only. Before I leave my house I always turn the wifi off on my Nexus so that the stupid connect feature won't run the app on my S6. Came back from Opening Day at Yankee Stadium and I realized that I left Spotify and the wifi enabled on my Nexus 5. So I simply uninstalled it on my S6 as an extreme measure and sure enough my S6 started to enter deep sleep again. Talk about a duh moment.
[T-Mobile Samsung Galaxy S6] greyhulk:
What is this connect feature? Is there no way to turn it off? I have Spotify installed. Does this drain show up anywhere in the battery stats?

I just got all of my playlists cached. I'd hate to remove it.
[T-Mobile Samsung Galaxy S6] NJGSII:
www.pocket-lint.com/news/132334-what-is-spotify-connect-and-why-does-it-matter

There is no way to disable it in the app. Like I said usually it aint an issue as I turn the wifi off on my Nexus 5 whenever I leave the house and that stops it from working. Me uninstalling it was a bit on the extreme side but I wanted to see if that was the issue.

In BBS it shows as Powermanager. wakelocks under kernel wakelocks . Back on the topic of the thread as my issue wasn't anything to do with the phone.
[T-Mobile Samsung Galaxy S6] JDM9499:
Correct me if I'm wrong, but Spotify's connect feature is only if you subscribe to their premium service right?

I do have Spotify. Don't use it much, so I don't pay for premium. I wonder if it will still be an issue?
[T-Mobile Samsung Galaxy S6] NJGSII:
You're correct. It's a premium feature only.
[T-Mobile Samsung Galaxy S6] ForgottenGuardian:
Glad we are all coming together trying to solve this issue. Even now that I don't have cell standby reported in the battery stats, my battery life is still so poor. I've already done the factory reset, turned off info stream, wifi calling, wifi, and VoLTE. I'm still getting less then four hours of screen time and about 14 hours of uptime.
[T-Mobile Samsung Galaxy S6] PunishedSnake:
Curious what are your average sot times
[T-Mobile Samsung Galaxy S6] chillsen:
i'm in the same situation as you, haven't done the factory reset (and not planning to bc i took so much time setting everything up), and did the OTA update first thing.

My question to you is, how much battery are you losing per hour? Yesterday I was at 5.2%/hr which is really bad. i got 2 hrs of display time before I had to charge my phone when it had reached to 10%.... yikes. Going to continue doing a couple more days with my usual everyday phone habits and then turn on greenify and see if it helps which it should. Also, I am on wifi all day with VoLTE on and wifi calling. I basically haven't deactivated anything because I hell, i shouldn't have to.
[T-Mobile Samsung Galaxy S6] JackieBrown:
Hate to say it, but hard reset is the only thing that fixed it for me. Went from losing half my battery (with almost not activity from me) in a few hours to losing about 5 % in 4 hours with minimal use.

A word of warning... The factory reset (at least the on in the setting menu) will delete everything off your phone. It warns you of this but I figured that was a "cover their ass" type of warning. I hadn't done a factory reset outside of TWRP in years. Completely my fault, just wanted to warn.
[T-Mobile Samsung Galaxy S6] ChristianBale:
I'm getting tired of waiting for a fix. It's been almost a week.
[T-Mobile Samsung Galaxy S6] greyhulk:
I'm actually a little scared that there will be an update. I'm rooted and can't fathom how I'd get to stock to apply an update, let alone root again.

I'd rather they just put a rush in 5.1.

[T-Mobile Samsung Galaxy S6] robertkoa:
I agree that the Battery is too small.

Ideally there will be a Galaxy S6 Pro at about 7.5 millimeters thick with a 3100Mah Battery at about $ 825 and

Power Users can do whatever they want for 8 to 10 hours.

I hope the influential Developers and Industry Types who follow XDA Developers can actually make this happen...

Though Samsung does not usually like to best the S Series except with the Note Series- maybe they will address this OR make a Version of S6 Active which can get VoLTE across multiple Carriers...with larger Battery etc.
[T-Mobile Samsung Galaxy S6] km8j:
You would just flash stock files.

[T-Mobile Samsung Galaxy S6] laureanop:
I don't have cell stand by issues, my phone sleeps as it should, I don't do gaming or CPU/ GPU intensive activities.

The truth is that this phone's battery life is avetage at best.

My average sot with my previous phones:

Nexus 6 5 hrs 5 minutes

Note 4 7 hrs 15 min

S5. 5 hrs 15 min

Nexus 5. 4 hrs 10 minutes

One more thing: ram management in this phone is atrocious. While using recents, if you go back 6 or 7 apps it reloads and refreshes ( a sign that is not on memory anymore). With my Nexus 6 I could go up to 70 deep ( yes, 70) and the redraws wouldn't start till 10-12 deep.

I'm still in my 15 day window...
[T-Mobile Samsung Galaxy S6] laureanop:
This being said, the screen and camera alone are worth the mid afternoon 30 minute charge. Tough decision when approaching the 15 day deadline
[T-Mobile Samsung Galaxy S6] greyhulk:
Off topic, I know, but I do find it odd that with a gig more RAM than the GS5, I consistently have less free RAM and a lot more reloads. What in the world is filling up the RAM all the time and why isn't it being managed better?

Maybe it's the RAM leak from the earlier Lollipop builds.

Sent from my SM-G920T
[T-Mobile Samsung Galaxy S6] B1aze:
The more RAM your phone has the more the applications will use. Free RAM is wasted RAM, it's a resource that's there to be used, and unused RAM is worthless to your device. Let it fill it up, if it needs some extra memory, it'll push some apps out of the queue. It's a 64-bit phone for goodness sake, mine has had pretty much every app open at the same time and hasn't slowed down yet.
[T-Mobile Samsung Galaxy S6] grantbey:
This. I was thinking it but you managed to express it more elegantly than me.
[T-Mobile Samsung Galaxy S6] greyhulk:
That would be a great explanation if the phone wasn't killing my browser tabs almost immediately after I switch to another app and then switch back. The poster above me was right. It's aggressively killing off apps and reloading content far more often than it should with 3gb of ram.

The old "free ram is wasted ram" is a favorite to regurgitate, but you're not evaluating the individual circumstances. This phone has less than 1gb after a fresh boot. Out of 3gb. That shouldn't be. Oh, and it's killing off apps shortly after you backround them, so I'm not really sure what it's using the ram for. My OnePlus One and Nexus 6 can keeps apps in the background for hours without reloading them.

Sent from my SM-G920T
[T-Mobile Samsung Galaxy S6] NJGSII:
I also noticed that the memory management is a bit on the agressive side with the device.
[T-Mobile Samsung Galaxy S6] laureanop:
I wouldn't call it a memory leak. Memory leaks frequently end up in reboots and system hangups which this phone does not exhibit.

I can make my preceding assessment about RAM management because I tested it by running my N6 and S6 side by side and after a minute of multitasking the same apps the N6 blows my S6 out of the water.
[T-Mobile Samsung Galaxy S6] bubblebuddyi:
But the N6 on 5.0.1 had a memory leak that was acknowledged and fixed on 5.1. So therefore we would have the memory leak on 5.0.2, and I believe we do.
[T-Mobile Samsung Galaxy S6] laureanop:
