Facebook causes significant battery drain if you look through the thread. Whatsapp is bad too, but not so bad you have to remove it. I use the web-browser for Facebook.

Spotify kills my battery life. I haven't tried music on the phone though.

I feel you, I came from a ZTE Zmax. That thing had RIDICULOUS battery life.

Your battery life is terrible. Here's a list of tips I made from what I gathered on XDA:

First of all to solve any problems with battery drain in sleep mode:

Factory reset your phone in recovery mode (home+volume up+power), then whipe the cache in the same menu. You may be able to get away with just whiping the cache, but that is up to you.

Disable VoLTE (open phone app, enter settings I think it's called enhanced 4g on ATT) and disable Wi-Fi calling

Whipe your cache again after re-installing everything.

Secondly to get more juice out of your phone:

Use the adaptive option for AMOLED settings. I like the cinema mode, but it seems to use slightly more battery

Auto-brightness

Do net let Google play auto-update apps over 4g. It will kill your battery. Find the setting in Google play

Disable Google Now, it's a gimmick

Disable all the bloatware by holding it and dragging it into the disable option

Bluetooth off, NFC off (add the NFC shortcut to the taskbar in case you ever want to use it by hitting edit).

Limit the use of home-screens and widgets

Disable the Facebbok app and Messenger app, they slaughter battery life.

Disable smart-stay

Disable Wi-Fi scanning

Use 4g if you have unlimited data. It is better than Wi-Fi.

Update Google Play Services

Disable Samsung Push Service if you don't use Samsung apps

Bonus tip: Enable your developer options and set all the animation scales to 0.5x and enjoy a blazing fast phone!

Ok on WIFI my phone is brilliant after reflashing stock recovery, could easily get 6 hours at home. It's as soon as I leave it, apps stay on "Mobile Active Radio".... this is becoming really frustrating now.
[Galaxy S6 General] aohmer:
Kind of sad that you need to do all this to increase battery life ..
[Galaxy S6 General] overloadedx:
Gsam bug

Probably the the highest % drain of phone radio ever.:D
[Galaxy S6 General] KingFaisal:
Of course it is. I tried to return the phone in store, but online orders (I pre-ordered in store smh) have to mail the phone back. What a hassle.

Samsung bloats their phones like an HP laptop in 2010, but honestly what alternative do I have?

I can give in and get a ZenFone 2 (the 1080p one) off eBay or wait for the Z4/G4. The LG will probably have similar battery life (5.5 inches after all) and the Xperia line have mediocre screens.
[Galaxy S6 General] valdigre:
Xperia Z's had mediocre screens up to Z2. I can see digitiser net on my Z2 screen in sund/bright day light, it sucks, but screens on Z3 are really really bright and nice!

Z4 should be even better, so...
[Galaxy S6 General] gigoypotpot:
Settings-lock screen/security-other security-trusted agents. Turn off samsung lock. Good luck!
[Galaxy S6 General] belloni:
Yeah I don't have "Trusted Agents" it seems, weird.
[Galaxy S6 General] gigoypotpot:
That is weird. Maybe carrier blocked/removed?
[Galaxy S6 General] guaneet:
I think it's only for Bluetooth devices. Like if you have a smart watch or a headset. It gets enabled with that.
[Galaxy S6 General] Sevael:
Exactly. Treat the disease, not the symptom. :)

For people who have high battery drain, there is clearly something causing it that needs to be found and fixed. It is not due to WiFi or mobile data or the like – it is due to something that uses those services that is getting stuck or just running poorly. Turning off entire services to stop battery drain is like cutting off your hand to fix a hangnail problem.

Not everyone has the time or patience to research such fixes, but there are solutions out there to most problems if people are willing to put in some effort. It sucks that some of you are forced to do this, but the fault mostly resides with third parties. Blaming Samsung for third-party issues isn't really fair, because as many of us can attest to, this phone is capable of fantastic battery life without disabling any services at all.
[Galaxy S6 General] gigoypotpot:
I am happy with my battery life with location always on and some other things on all the time. But id like to get a set of other eyes on my stats pls and tell me if these stats are good.

Also, cell standby is higher than anything else? Is that normal, or should i depend on gsam stats more as it is more accurate?

Please advise. Thanks!!
[Galaxy S6 General] zainch17:
Battery seems to be good to me,6.30h sot time on just my second charge
[Galaxy S6 General] KingFaisal:
If you don't have a lock screen it won't show up.
[Galaxy S6 General] cellsafemode:
This occurs if VoLTE is enabled. If you dont care about that feature and want to save some battery, go into phone app, goto more, and uncheck the setting.

If you dont need lte speed or if coverage is weak, disabling lte will help even more.
[Galaxy S6 General] gigoypotpot:
Awesome!! I have been wondering where the VoLTE settings were!! Thanks so much! I shall report back with (hopefully) much better stats.
[Galaxy S6 General] krabban:
oh thats great i dont even get 4 hours SOT

---------- Post added at 08:53 PM ---------- Previous post was at 08:49 PM ----------

how do you get that good SOT?? airplanemode or what? sounds to good to be true =)
[Galaxy S6 General] stratplayer:
My battery for today.... 8 days now still no better. I've tried cache, disabling stuff to no avail.

Called Samsung today and they said to try in safe mode... they are also connecting to my phone to check my settings. .. I'm an android veteran
[Galaxy S6 General] zainch17:
I don't know its just was my second charge and didn't played with settings yet(e.g disabling or uninstalling the apps),I used youtube,some games,checking yahoo mails,playing more tham a hour music from deezer app etc.

According to open signal app mobile was connected to 34% with 4g and rest with 3g(Because after fews hours because of bad signal i was turned off 4g)
[Galaxy S6 General] gigoypotpot:
I was getting decent batt right from the get go, but i did a full reset yesterday and the batt is just waaaaayyy better. Im not sure if you have tried it, but it was worth it for me. Wasnt even any trouble since everything was backed up and the s6 is super easy to set up :)
[Galaxy S6 General] nutzy73:
'Boy get rid of that horrible Galaxy S2 font! :p
[Galaxy S6 General] gigoypotpot:
Lol!!!! I cant get myself to like the other ones...guess u can say im old school!!! :cool::cool:
[Galaxy S6 General] LNJ:
The N5 would drain battery by just looking at it. Even at its worst, the S6 has better battery life!

Anyway disabling Smart Lock seems to have made a difference slightly.
[Galaxy S6 General] amieldl143:
After one week and half my battery is good.did intense heavy use morning 2hours 78percent at lunch now51 .using nonstop..for 45 mins
[Galaxy S6 General] abeln2672:
OK, I'm going to humble myself and ask for help here and on AC. This is my 4th day with the phone on Sprint, and my battery life absolutely sucks. 2.5 SoT maximum. Poor standby time. The second I take it off the charger in the morning, it starts plummeting. I've tried lots of tweaks: WiFi calling and scanning off, WiFi off when sleeping, auto brightness (usually very low), location on GPS only, location history off. Was worried LTE signal was the issue, so I switched my radio to CDMA only. My M7 was fine at home and work, and my wife's iPhone 6 is fine at home, but I'm trying it anyway...I'm desperate. I hate to be melodramatic, but this is breaking my heart. I LOVE the phone other than this. It's my 7th (?) Android, but I'm so close to returning it.

*By the way, I restarted at about 83% this morning when I switched from LTE to CDMA, so that's the discrepancy with use time. But essentially, I took it off the charger at 7:45 am, and it's now 3:30 pm at 20%. Over 10% an hour with light use. I also obviously took the app sucker photo later than the others...30 min later, and down 7% more :( Any help or suggestions? Am I just screwed?
[Galaxy S6 General] krabban:
Ok sounds good hope mine will get better. Are you on stock rom?
[Galaxy S6 General] zainch17:
Yes using stock rom,or you using any power saving setting?
[Galaxy S6 General] stratplayer:
Going to try that tomorrow, I haven't tried it as yet.
[Galaxy S6 General] gigoypotpot:
Turn off VoLTE if u dont need it, turn off samsung lock if u dont need it. Wipe cache see if that helps. Otherwise do a full wipe and that should help. :) helped me doing those things!!
[Galaxy S6 General] cellsafemode:
Your abnormal system and OS power usage makes me think that the OS restored an invalid setting when you set the device up and selected to restore apps and settings / or that it is trying to do something that is failing at the kernel level. You have a couple easy options.

First, did you install the update for Samsung Push (sometimes play store doesn't auto update this app even though if you manually search it will say an update is available).

Second, disable the usual suspects. Disable wifi calling, disable volte and disable auto-screen brightness and auto-screen color. If possible, disable LTE and just use 4g.

If over the course of a fresh day with that stuff done you still see the same high system and os usage, the final thing you can try is doing a full factory reset and not restoring apps/data when you set the device back up.

you should expect around 24 hours of battery life easily with this phone under normal use ...way more if you use the power saving modes.

(full disclosure, Chrome is my most used app and I dont use social networking applications, if you do your battery life can be expected to be much shorter than 24 hours due to push notifications)
[Galaxy S6 General] abeln2672:
Just wanted to thank you both for replying. I'm truly in desperation mode, so even hearing from people helps me feel a bit better. BTW, I did the Samsung Push update right away, and I've also got that disabled (along with most other Samsung and unused apps). I think I'm just going to take the leap and do a factory reset. I transferred data from my M7 using the "tap" feature, so I'm hoping there's some rogue setting that's causing all this. I'll set it up as a totally fresh phone and see if that helps.
[Galaxy S6 General] eyekyu:
so VoLTE is bad to have on? cell standby eats the sh!t outta my battery

If you have rooted and installed twrp see the folliwing to fix battery drain.

So the cell standby is a non issue if I turn off WiFi but Google Play Services is killing me. Always using up 15% or more of my battery.

No root, weak vzw ...

But thanks for the info

s6 made me do it
[Galaxy S6 General] elbos2k:
Maybe you have Location history enabled.
[Galaxy S6 General] cheetah2k:
Didn't work mate..... Still massive amount of radio on time. more than my screen was on. Yesterday was like 5+hrs radio active, but only 1.5hrs screen on time. I had even disabled notifications in the FB application :( I noticed its doing the same thing on my wife's Z3C, even with the same features disabled. FB application never used to do this before the last update, but I can't roll back to an older version to test it. It seems the application forces the radio to stay on, even though there are no updates or messages..

I have sent a problem report to FB but I doubt they will even listen.

In the mean time I've removed the FB app, and accessing FB via Chrome, which has made a massive difference for me with battery life too :) :good:
[Galaxy S6 General] KingFaisal:
Disabling Samsung Push Services and updating Google Play Services have elevated me to 6 hours of screen on time.
[Galaxy S6 General] ChristianBale:
What does location history do?
[Galaxy S6 General] elbos2k:
Pulls information from your GPS...
[Galaxy S6 General] elbos2k:
I love this phone...
[Galaxy S6 General] big_b0sss:
here is what i did:

wifi always scan off

bluetooth nfc off

changed to 3g from 4g

vibration off (ringing, feedback & keyboard)

location wifi & mobile network

and google location history turned off

report diagnostic info off

on the google account i got all the unused services sync off (g+, google music, movies etc.)

i got few of my apps restricted for background data.

google now turned off

installed LUX from play store and got an aggressive profile which seems to offer better brightness (slightly lower than the built in auto brightness) plus i can go even beyond 0%.

i have to tell ive been hitting 4+ SOT for 3 days now. very very satisfied with battery.

Edit: thought I should share the lux profile with you guys

[Galaxy S6 General] richyb86:
WiFi always on

GPS only on

Sync on (1 Gmail account )

Bluetooth on

Autobrightness on

Facebook

Twitter

Snap chat

Gplus

Fbmessenger

Location history and reporting off

Google now off (as it kept polling gps for no reason even with my select cards)

Smart lock off

Samsung push disabled

NFC off

Play services updated.

Considering the battery size, Screen size and how blazingly fast the phone is...I'm quite chuffed
[Galaxy S6 General] krabban:
Omg im not even close to that. Stock rom? What settings

Are you using?
[Galaxy S6 General] flu13:
An update to the app on the 16th was supposed to reduce the power consumption by Samsung Push Service.
[Galaxy S6 General] elbos2k:
Stock rom...
[Galaxy S6 General] FlowingAway:
I charged mine to 100% and then took it off the charger.

2 hours later I am down to 92%, which may sound good BUT consider the following:

Airplane mode with only Wifi enabled the entire time.

Screen on Time: 5 minutes.

Android System 12.2% of battery

Kernel 6.6%

Screen 29%

Wifi Active 36%

Location history and the other stuff is already turned off.

This is coming from a factory reset last night and a minimal set of apps installed, none of which are showing up very highly on the GSAM battery monitor app sucker info.

Samsung apps disabled too.

Newest play services update installed.

I'm at a loss here.
[Galaxy S6 General] flu13:
That doesn't seem so crazy. You drained 8% in two hours, with 2.32% of that being from the screen being on for five minutes. That means that in 2 hours, your phone drained 5.68% of it's battery, which would give you a projected time of around 35 hours without the screen on. I'd be more concerned about the 2.32% drain from the screen in 5 minutes. That gives you a screen on time of 3.5 hours, which seems maybe slightly low based on what others are reporting. What do your display settings look like?

Using better battery stats , what is your deep sleep percentage compared to awake , i lose less than 0.5% in standby with 3G and wifi on after doing some clean up and using greenify , it helps that i have FB disabled and whatsapp is the only data consuming app
[Galaxy S6 General] gorilla p:
I recommend reading the optimal battery life document on bit.ly/makostuff.

The makostuff site is primarily for the Nexus⁴, but the optimal battery life app applies to all phones.

Lots of helpful tips, especially for beginners.
[Galaxy S6 General] FlowingAway:
My screen settings are plain and simple auto brightness and nothing more.
[Galaxy S6 General] robertkoa:
I played around with an AT&T S6 last night and one thing that seemed odd was the screen seemed very dim at 10% to even 30% brightness.

My Alpha although much lower res is FAR brighter at the bottom of the scale.

Is this merely Calibration or the result of so many pixels per inch that the screen needs a lot of power to even look "normal" not dim ?

Indoors in fairly low light what screen brightness are you guys using?

I really think aside from being thicker with 3100 Mah Battery the S6 could have a 450 ppi or so and only *.0147% of people would notice .

* estimated error +/- 500% lol.
[Galaxy S6 General] flu13:
Auto brightness is actually a decent power drain. If you're looking to maximize battery, turn off auto-brightness and set the brightness as low as you can tolerate in the conditions.
[Galaxy S6 General] stargate1000:
This is my battery life. After a week of piss poor battery I took the plunge and factory reset.

After getting barely 2.5 hours SOT I'm now getting 4.5 to over 5. I'm a pretty heavy user as my phone is alway in my hand and its used most of the day. Now I'm happy.
[Galaxy S6 General] barondebxl:
Factory reset ftw
[Galaxy S6 General] FlowingAway:
I have factory reset multiple times to no avail. Screen and google services and kernel are my killers no matter what. Most google services such as location are off.

[Galaxy S6 General] jasonm253:
I thought I was getting great battery life before but I wasn't in deep sleep until yesterday. This is the battery life I have got recently. I rooted the phone and flashed stock recovery like mentioned. I am finally satisfied with everything now. Will still order the morphie when available.
[Galaxy S6 General] scarchelli:
I am literally considering doing the same thing. My 14 days is up in 90 minutes lol. Get a gold sprint 64 gb leased like my 32 gb black? Likely $7 more per month I was told on the phone.

[Galaxy S6 General] X-Ter:
How do I use this profile? Don't you have different profiles for day and night?
[Galaxy S6 General] sasha101:
Okay so I was having issues with the battery. I found out it was because my phone wasn't going into deep sleep.

After flashing the stock recovery then the twrp, my phone seems to go into deep sleep now. I can see an increase in battery.

My question is, is it normal for deep sleep to be like 10%? I was using CPUspy, reset the timer, and shut my screen off. After checking it after about 20 minutes, the deep sleep was around 14% while the 400mhz was crazy at like 50%

Is that an issue or is it normal?
[Galaxy S6 General] barondebxl:
Bad a** fingerprint magnet. Better than touch ID lol
[Galaxy S6 General] FlowingAway:
I've had it running for 4 hours 49 minutes now and deep sleep is 67% screen is 37% at 1 hour 44 minutes.
[Galaxy S6 General] eyekyu:
I mean wtf!!!

s6 made me do it
[Galaxy S6 General] se1000:
No this isn't normal, under those circumstances your deep sleep should be like 90%

So, I'm on my third day and maybe it's just me but battery life seems to have improved for no reason. Anyone here notice battery "break in"?

[Galaxy S6 General] BoneXDA:
Hey, thx.

Would not read too much into this though, GSMA probably used the pre-release S6 they got in Barcelona for this review with pre-release SW. At this point, a month away, there's plenty of work to do, and who knows, the first update that usually comes at the launch date may be to Android 5.1 which seemingly rewrote the battery and performance history of the Nexus 6, for the positive. We just need to wait for the retail units with retail SW, this applies to all parts of the S6 experience.
[Galaxy S6 General] matheus_sc:
So s6 battery life is bad in review, for me dont make a half day and 4 hrs of sot based in gsm arena review
[Galaxy S6 General] rkial:
So the battery life is on par with flagships from 2 years ago... Good job Sammy. Every one is moving ahead, samsung bravely deciding to stand their ground.
[Galaxy S6 General] aliHTCDHD:
I love the way your trying to stay positive but I gotta break it to you. Reviews came out two weeks after mwc. The handset they have reviewed has been sent to them from Samsung. The device they tested therefore isn't a demo or running really beta sw. Samsung's really let you powers users down. I'm getting the m9 personally but if you guys love Sammy go ahead. I just don't understand what was ever good about the s series. The sw was really bad looking, speakers bad quality, battery was normal and display was horrible till s4. It seems that people who buy Samsung are power users, love removable sd card, feature rich and battery. Now that's gone you guys will probably jump ship or wait for Note 5. Whatever you guys do GL :D
[Galaxy S6 General] Applesexual:
Well, I want a premium-feeling device, and people and reviewers have said that the M9 felt like a cheap, used car compared to the S6.

TouchWiz is now more optimized than Sense, with Anandtech reporting the M9 stutters.

M9 will probably have a worse battery life than the S6 if G Flex 2 is anything to go by.

The camera on the M9 is also terrible.

The S6 is just superior in way more categories than the M9. The only thing the M9 has over the S6 is expandable SD card and slightly better speakers.
[Galaxy S6 General] Lympe:
It's strange. In the presentation Samsung said wifi browsing time will be 12 hours and in the review scores 8.40. That's a big difference as last year they claimed 10 hours for s5 and got 9.40 in the review.
[Galaxy S6 General] megagodx:
GSMArena often runs quickly rushed, premature reviews several weeks or a month before proper reviews are published. Also, their testing methodology on the display quality and battery life is quite poor and inaccurate. I wouldn't jump the gun until we get to around April. That's when the embargo lifts and more reviews that took a better quality control route will be available to paint us a better picture.
[Galaxy S6 General] Lympe:
Yeah but 20 hours difference it's way too much to cover.
[Galaxy S6 General] dandroid13:
But a larger battery means the device would be thicker and charging times longer. The ten minutes charge = 4 hours of usage is amazing, even if I can't make it through two days or so with a single charge.

Enviado do meu Galaxy S5
[Galaxy S6 General] CLARiiON:
20hrs? You mean that 'endurance' rating in GSMArena? I still don't understand why people value that weird endurance rating over regular category score? That endurance is nothing but just a glorified standby rating. How many phones have you seen run for 3-4 days and yet performing 1hr of browsing and movie per day? That's a useless stat.

Fact: Battery capacity reduced by 9% compared to S5. So, if everything else remains same, batterylife should be reduced around that level (say 10% approx)

But everything has not remained same -

1. We have a QHD display, and everyone suspects it will drain even more battery. Fact is QHD in S6 drains less battery than FHD in S5. 20% more efficient display.

2. The process is more advanced. We had a 28nm processor in S5, and a freaking 14nm in S6. While it doesn't mean 50% less battery, it does mean that this processor will be lot more efficient than the one in S5.

3. Samsung itself mentioned in keynote 12 hrs batterylife.

They did the same in S5 (claimed 10hrs), and it proved right in testing.

I see no reason why it should be be any different for S6. When you claim infront of everyone in public, I am sure they tested this before putting it in big bold numbers.

4. This review looks totally rushed, claiming S5 has better speakers (really?). They also say S5 has higher brightness than S6 (bad analysis by GSMArena, check Displaymate for detailed tests). They even used the same photos taken at MWC event.

5. It also uses Broadcom's BCM4773 chip which integrates many different components to save battery.

Source: http://tweakers.net/nieuws/101681/g...ij-locatiebepaling-dankzij-speciale-chip.html

Wait for some proper testing from other web sites like Anandtech.
[Galaxy S6 General] i9100g user:
Agree with all points made above.

Even if the battery life is poor it would be too early to conclude that , given the lack of reviews we have.

Heck even GSM arena may have that unit running on pre release SW.

Well time will tell.
[Galaxy S6 General] CLARiiON:
That's the biggest point, isn't it??
