I ended up discovering it's my signal that drains it at work I think. Because I can get almost 4 SOT now at home on wifi. But it's kind of strange my M9 OR 6P doesn't drain nearly that fast in poor signal. Sure they drain faster in poor signal, but not that fast.

I will turn LTE off and just do WCDMA/GSM setting. That should keep it from switching back and forth between LTE and 4G. That way stays on 4G only when I'm at work. I'll update next week if that resolved it at work.
[Galaxy S6 General] Pratz852:
Without wifi?!

Could you please share your settings?
[Galaxy S6 General] zebster:
Be aware that the SoT shown on gsam app isn't the same as the battery log. It's always higher.
[Galaxy S6 General] mariodiniz21:
For more than a month I researched every site and video to maximize the battery and tested alot, I don't even know everything I already did.

Yes, no wi-fi, 3G on all the time, some phone calls and bluetooth on some hours as you can see. Screen light auto-on at 50% to 70%.

The most important thing if you think you have battery drain is to uninstall updates on Google Play Services and update it again from the Play Store. Also some apps will always update on the background, so for Facebook, Facebook Messenger, Instagram, etc. restrict the Mobile Data, strangely you will still receive push notifications anyway so it's a win-win situation because it won't keep the radio on all the time but will work anyways. Just don't do this with Whatsapp and Viber because you won't get push notifications.

These two things are the most important, but there are always alot of small things that you can do, if you want to ask it is ok. Ah, I don't use power saving mode, it doesn't save much battery and the phone gets awful.

About the SOT on Gsam, sometimes it is higher than in the official battery log, sometime it is lower, and sometimes it is exactly the same but it never is much different. In my battery log I had 1:40h of phone calls and in Gsam it only shows 1:20h, so it depends.
[Galaxy S6 General] Lucoso46:
Guys i saw a little improvment on the Marshmallow Beta for S6.

I'll talk later and post some screenshots about SOT and Deep Sleep.

For now seems good battery : i think the system is lighter and the optimization is better than Lollipop.
[Galaxy S6 General] cavags5:
I think its worst.

Don't test it yet how i have things in lollipop but I already charge it 3 times .this last time to 100
[Galaxy S6 General] NannyFe:
SoT: 2:39

Remaining: 33%

Full brightness, save mode, stock rom and kernel with normal usage. Using Package Disable Pro. Top Eleven, Youtube and many internet using. Think thats the best result with Android 5.1.1
[Galaxy S6 General] WolfsFang:
Man this cell standby is killing me. 15h on and 29% cell standby with time on also being for 15 hours, I was only on mobile data for 4 hours today.

MM battery stats

Actually i think is amazing!
[Galaxy S6 General] pdxrealtor:
You guys- turn off Google now cards.... Problem solved. Just try it, then enable one thing at a time until you realize nothing you've disabled will eat your battery.

It's all about disabling Google now.
[Galaxy S6 General] dandrumheller:
I agree with this. Watch the frequency of Google wake alarms with now cards on and now cards off. Now cards and location history take a significant toll on battery.
[Galaxy S6 General] cavags5:
I definitely say its worst.
[Galaxy S6 General] sintro:
Anybody get a wifi drain? I lose 3-5% an hour when I have wifi on, even though my phone is in deep sleep 97%+ of the time. GSAM shows wifi using up to 60% of my battery sometimes. I do not get the drain when on data. When strictly on data, I will lose at most a percent an hour, and I have a crappy signal (one or two bars of 3g).

I've had this problem since release of the phone. I'm using a 920r4, US Cellular CDMA variant
[Galaxy S6 General] theronlas:
What sort of wifi link? many large scale ones with per-user authentication are serious battery hogs.
[Galaxy S6 General] kinghu:
Getting good battery on the beta. Mostly WiFi but much better than Lollipop. Doze seems to be ok too... about 3% overnight compared to 10-12% 5.11.
[Galaxy S6 General] geoff5093:
Did you and I read the same post? He didn't say "I think it will be over 2600". He yelled in all caps that we are all wrong and he is right that it will be over 2600 over and over again.

[Galaxy S6 General] jptech:
Just picked up on this thread

Has anyone mentioned or thought of the fact that with the 14nm process on the exynos, you're going to get longer life out of less battery because it uses less power?
[Galaxy S6 General] tmac31:
14nm alone doesnt say alot. it just means if you make 2 same soc. 1 with 20 nm 1 with 14nm. 14 nm version will be more efficent. but a 14 nm soc still can use more power than a 40 nm completly different soc.

[Galaxy S6 General] Shawn haz root:
I know there isn't enough facts out there yet but I was wondering what you guys thought the battery life would be like compared to a Droid Razr HD Maxx. I am thinking about upgrading to the s6 but I love having the life to go all day.
[Galaxy S6 General] ChristianBale:
Just got my S6 today and Cell Standby is eating all of my battery up. Any suggestions as to what would fix it?
[Galaxy S6 General] poweroutlet:
I'm having the same issue. The cell radio is eating up everything, I couldn't even make it through a single day without having to recharge. Love everything about the phone so far but I'm pretty disappointed bout the battery life so far.
[Galaxy S6 General] ChristianBale:
I'm glad to know that I'm not the only one with the issue. Who is your carrier? I have T-Mobile and they have WiFi calling so I'm going to see if disabling WiFi calling helps at all.
[Galaxy S6 General] poweroutlet:
TMO as well. I wasn't on WiFi calling though, but I was in an area with relatively poor cell reception which certainly doesn't help the battery.
[Galaxy S6 General] ChristianBale:
Interesting. I'll let you know if my disabling WiFi Calling helps at all. Seems like there are some similar issues with the Edge: http://xdaforums.com/galaxy-s6-edge/general/galaxy-s6-edge-battery-life-t3068598/page3
[Galaxy S6 General] greyhulk:
I have had my GS6 for two days. So far, battery isn't stellar at all. I'm lucky to make it through the day with very little use. I've checked for all the usual suspects and used App Ops to turn off "keep awake" for a lot of apps and it has made no difference. Wakelock detector won't even work (I'm rooted), so I'm still trying to find a way to check for those.

It might be the cell reception, as cell standby is #1, but my Nexus 6 destroys my GS6 in battery life (using them both at the same time right now). Hope I can solve this because I love everything else about this phone.
[Galaxy S6 General] MysteriousDiary:
A problem with the sim-card can also produce this kind of problem. If this should turn out as a problem that many run into the carrier might have to change them.
[Galaxy S6 General] Shawn haz root:
Thanks very disappointing to hear.
[Galaxy S6 General] onthecouchagain:
Those that are on T-Mobile, did you get reception issues with your previous device as well? I'm winding if it's T-Mobile or the s6 causing all that cell stand by...
[Galaxy S6 General] jbdan:
Cell standby on Nexus 6 with tmo was major issue with 5.0.x but was fixed with 5.1. Maybe the same lies here in with the GS6? Idk
[Galaxy S6 General] ChristianBale:
No previous issues with reception.
[Galaxy S6 General] entropism:
I had reception issues, but I was on a Nexus 5, which is known to have a ridiculously weak radio. Reception on the S6 is better, but the drain is awful.
[Galaxy S6 General] onthecouchagain:
Argh, that's a bit alarming.

Maybe as the poster mentioned above, it has something to do with 5.0.1....

What was that recent Tmobile update that they pushed out to the S6 a day or so ago?
[Galaxy S6 General] jamezr:
yep....you might see more carrier updates soon. I heard on other forums 5.0.1 has issues with battery drain.
[Galaxy S6 General] onthecouchagain:
Is there any word on 5.1 coming from Samsung? Not that I'm holding my breath...
[Galaxy S6 General] WolfsFang:
Well for some strange reason can't upload the main battery screen since it's saying the file is to big....

16h,21m for today, connected to WiFi 100% of the day. I really hope marshmallow improves my battery life, if not this will be my last Samsung device.
[Galaxy S6 General] vnvman:
Still no problem here, I can get to the end of day with 50%+ battery and 3+ hours SOT after a day under WiFi, same goes for when I'm using mobile data, I just get maybe 20-30% less by the end of the day depending on usage and the area I'm in. Honestly it could be better (it can always be), but for my usage I'm pretty far from complaining. I can easily get 6+ hrs SOT into a 15 hours or so window, but that would mean dicking around all day with my phone in my hand and achieving nothing so that's not really normal usage for me lol.
[Galaxy S6 General] Dexter_prog:
I just got this mobile and I think the battery is terrible. With average usage I'm getting 12 hours at most. It drains as fast as my 5-year old S2. This is a big disappointment for me. I'll root it tomorrow and remove samsung bloatware to see if it gets better.
[Galaxy S6 General] vagelis74:
Without root remove Samsung bloatware with package disabler pro from play store

[Galaxy S6 General] Dexter_prog:
Yeah, I just did that using the guide you guys posted here. I'll charge it to 100% while I sleep and we'll see how this turns out. I'm still disappointed in this phone not lasting at least 20 hours straight out of the box... and I modded the S2 A LOT. I just assumed newer phones would have better battery life. Instead we get 2k and 4k resolutions (what for?) and a million cores to run whatsapp and facebook 80% of the time.
[Galaxy S6 General] CRiSTiANVASiLE:
What do you think?
[Galaxy S6 General] HaGii:
What should i think about thee screenshot? :D

You just show battery stats without any info. At least make a screenshot of the SOT. ;)

But 2 hours of SOT with 49% left isn't the best score I've seen.
[Galaxy S6 General] vnvman:
Yep, I usually get 3 by the time I hit the 50% mark
[Galaxy S6 General] vteccorp:
S6 battery life make me very happy :D

I have usually about 2 days / 6 hours SOT.

I clean some bloatware, always turn on FlightMode when i go sleep, turn on WiFi or 3/4G data only when I need it. I rarely play games, listen quite a lot of music, talk more or less 1h, send dozens of sms, write some emails... per day.

With heavier use: about 1 day / 4-5 hours SOT (more internet, some gaming)

With a slight using: over 3 days / 7,5 hours SOT (little Internet, checking the mailbox, few weather services synchronizations ...only)

I'm not a heavy user, i know, but on old S2 with the same usage i have usually only 2-2,5 hours SOT... :p

Sorry for bad english...
[Galaxy S6 General] WolfsFang:
I have no idea how you guys get this SoT when I can only push around 3 hours connected to WiFi for the whole day.
[Galaxy S6 General] botanicfts:
I do not know too how to get more than 3 hours sot, i have only 3 on wifi, on mobile InternetI'm not saying anything because after 2 hours i can get 30% battery. All bloatware are deleted, dont know what should i do
[Galaxy S6 General] Dexter_prog:
I think the problem is that there is no standard way to test battery life, for example see the post above you. It must be one of the most non-standard uses of a mobile phone, so no wonder he gets so much battery.

Perhaps we could set some ground rules for testing and reporting battery life. For example: 2 tests with different connectivity settings (one with wifi on and connected 24/7, one with it off and LTE/H/3G on 24/7), etc.
[Galaxy S6 General] Dexter_prog:
What do you guys think of this?

Usage conditions

Wifi on 24/7

Location, blutooth off

Mobile networks on (LTE preferred, but wifi was on all the time)

Sync on 24/7

Services disabled according to: http://trendblog.net/increase-samsung-galaxy-s6-battery-life/

Usage:

Minimal to no usage: left the phone in my room all the time. Only used it to occasionally check emails and visit this forum. Looked at some pictures and browsed some websites.
[Galaxy S6 General] AndroidPurity:
wtf?! Over 6 hours of SOT on an S6?! That is the kind of battery I get on my 6P with 850mah more of a battery! Are you sure that is not your Note 5 and not the S6 edge?

Anyways glad to hear doze finally fixes the idle battery drain, that should help my S6 a lot. I do not know how you guys get screen time at the top. Even when I am on WiFi all day with about 25% screen brightness I am getting about 4.5 hours of SOT with Cell Standby and Android System STILL at the top. I have attached my screen shots. It just does not make sense how this cell radio can drain so much, especially while on wifi and in pretty good signal area (4 out of 5 bars usually). 4.5 hours is pretty good for this size battery on WiFi but still just does not make sense.
[Galaxy S6 General] bigpp85:
not too bad
[Galaxy S6 General] WolfsFang:
Here are my results for the day. I would say phone usage was about average, with most of my day today consisting of text messages and reddit (dark theme). Extremely light gaming and and on WiFi for about 70% of the day.
[Galaxy S6 General] tuk1maar:
My brother also owns an Galaxy S6 (fully stock) and he gets daily 6 to 7 SOT....My father owns an S6 aswell and he gets these results aswell. A friend of mine does not. His S6 is kinda broken from the factory. He can't get more than 4 SOT, speaker malfunctions like madness as well. So I guess it depends on the phone you got?
[Galaxy S6 General] HaGii:
And your provider.

Bad cell coverage results in bad battery life and vice versa. Cell coverage is one of the main culprits.
[Galaxy S6 General] AndroidPurity:
What providers are they on?

I would think it was my cell coverage too but I'm on WiFi the entire time when I get 4.5 SOT and 4 out of 5 bars. So it can't beven due to poor signal in the scenario I posted.

But you got me wondering if it's the radio.img for some (or one) carriers that has a standby battery drain bug. Because each different S6 probably has a slightly different radio.img right? Despite same android version between them. If so, that could explain why high cell standby is high battery usage for some but not others.
[Galaxy S6 General] Lucoso46:
Hi Guys. This morning i installed an app called Synapse, and i wanted to undervolt (-75 mV) everything and also underclock.

My phone afeter 5 to 10 minutes of usage restarted, but it was less power consuption and from 100 to 90 I did 1 SoT. Anyone can post some screenshot or can teach me how to undervolt? Thanks.

I was on Back To Not3 v 13.1 with arte97 kernel v10(x)
[Galaxy S6 General] HaGii:
Why not? It could be everything. [emoji14]

But I wonder if you were in airplane mode when using your phone in WiFi. Otherwise bad cell coverage can be the issue for you as well.

[Galaxy S6 General] AndroidPurity:
Yeah I have thought about doing a test with airplane mode on at home on WiFi all day. Just never got around to it. Maybe this weekend when I'm home. I'll report back my results when ever I do it.

Not sure how to exactly explain it. But best way I can explain its the image that contains all the code for the radio antenna that controls the signal your phone gets. It controls at how strong the signal needs to be for it to stay on that frequency signal or change to a stronger frequency signal in the area, and it controls how often its scanning for other frequencies. Anything and everything related to the signal in a phone. It is an image that exists in every phone.
[Galaxy S6 General] pnr2020:
Thats good about the same as me
[Galaxy S6 General] shaxs:
Holy hell this is the worst battery life I have ever had in any phone. It drains 1% a minute with the screen on. Best I have gotten was 10 hours on battery and just under 2 hours SOT. Its unfortunate I cannot root and keep Samsung pay so I can stop some of the draining.

Disable Volte, Wipe cache partition or do a Factory Reset and disable the apps you don't use help a lot of users.

So i had your problem with the s6 i put in airplane mode and mute.

10 Hours of sleep and 0% consumed. :)
[Galaxy S6 General] WolfsFang:
I don't even understand, this is by far the worse phone I have ever used and will be the last Samsung device I buy.
[Galaxy S6 General] cavags5:
There is some serious problem with your phone, that should not happen.

Do you try hard reset,?
[Galaxy S6 General] WolfsFang:
No not yet, my phone was on a wireless charger (samsung), my alarm went off at 11, don't know why it was draining while charging but the phone was really hot on the right side. I am also on tmoblile with WiFi calling on so from what I have read it can't be a radio problem, to also add if I am not on WiFi I have full bars lte.
[Galaxy S6 General] cavags5:
First when is charging turn off everything, wifi doesn't heat much, but LTE with charging it will burn for sure in any phone.

But do first a hard reset, don't forget back up your data,and then you disable what you don't need, and im sure you can get 5h or more sot.

But if the problem persist could be a problem with wireless charging
[Galaxy S6 General] TheDKGunner:
This is kind of a regular weekend for me... All stock... Everything syncs (Facebook, Twitter, Instagram, snapchat, LinkedIn, Google, notes traveler etc.), screen brightness at 50% and auto. I really think a lot of people tinker themselves into problems when trying to optimize.

Stock 5.1.1 unrooted on Verizon: Obviously the all black theme helps but even when I go back to stock theme, I can get around 4.5 - 5 hours on screen time @ 20℅ brightness too. I'm actually pretty satisfied lol

Obviously I disabled all that Samsung crap apps, didn't use Package Disabler, not using Official Facebook app, no Greenify, location set to High Accuracy with location history enabled, Google services all syncing, but Google Now off.

Listened to music for 4 hours with screen on and off while using Tinfoil for Facebook and Reddit.

I also got rid of the cell standby drain issue on Verizon.

It sucks that in order to get good battery life you have disable all the features that make it useful .
[Galaxy S6 General] Lucoso46:
Every one can do what he wants.

You have to disable a lot of bloatware that (for my case) i don't need.
[Galaxy S6 General] cretu01:
This is battery drain overnight with SOT about 10mins. Last day my phone was 40% when i got home at 8 p.m. with 1h SOT no gaming and google play services, android os android system and google app among the first places in battery usage. Is that normal?
[Galaxy S6 General] WolfsFang:
Not going to post SS but since that freak accident 2 days ago my battery life had been great, with no hard reset needed.

1 day 40m the phone has been on and I'm going to charge the phone now when it has 46% left. At the time of this posting my SoT will hit 3 hours.

[Galaxy S6 General] Fullmetal Jun:
Haha! Addicted to your S6! Me too!

On topic: Most other devices have average battery life like us if not worse with bigger mAh! Only Xperias get about 0.5-1 hour more sot!
[Galaxy S6 General] shaxs:
Here are some screens of my battery life. It truly is atrocious.
[Galaxy S6 General] botanicfts:
Thats all in home with WIFI, normally I can not make more than 3 hours SOT with mobile data, its not inconceivable that the flagship phone does not stand a whole day working with Internet enabled and the screen at 20%. something is wrong with this devices, because i got -5% battery on 10 min SOT, thats impossible.

Through the night -15% with WIFI off, i did all from this topic http://xdaforums.com/android/general/guide-extreme-battery-life-t3095884 and i think thats doesnt help me a lot. all amplify, greenify etc. does not make sense, S6 anyway has a weak battery and optimize its consumption.

Hi Guys! Before i tested Marshmallow and i saw not great battery life.

Now I'm running XtreStoLite 2.1 so less bloatware and I hope there is better.

Also i undervolt the Cpu.

I will update you tomorrow. :)

---------- Post added at 09:02 PM ---------- Previous post was at 09:00 PM ----------

Try factory reset and change the Rom.

which ROM do you recommend?
[Galaxy S6 General] pnr2020:
Before marshmallow I was running XtreStolite 2.4 great battery and never had any problems
[Galaxy S6 General] Lucoso46:
For battery XtreStoLite 2.4 Deo Mod and 2.1 but the eal difference is the kernel.

I think both roms are great.

why 2.4 and 2.1, it is between these versions there a difference? also you recommend these roms and which kernel?
