Since I got the AT&T update, did a factory reset, I have left everything on, Enhanced LTE, Wifi etc. and am seeing 2-3% per hour drain. Very acceptable. Cell standby shows up in the battery stats, but since overall drain is acceptable, who cares? From time to time work takes me inside a jail, where there is no service, so I put it in airplane mode while there, but i have had to do that will all my phones for years and years.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
The battery life is horrible no matter what. I freeze over 60 items and they still show up in stats.

With that said there seems to be little you can do without impacting performanc. As I stated about losing notifications, etc.

I've tried android assistant, battery saver, deep sleep, clean master, greenify, even the standard power saving mode all kill notifications and break background uploads and such. I pretty much have to stay tethered to a charger.

I checked with that code and it was enabled. So much for that theory
[AT&T Samsung Galaxy S6 Edge] SupahDave:
I don't know why some people are still having battery drain issues but the OE2 update completely fixed my problem. This is with about 2.5 hrs of screen on time and an even mix of Wifi and LTE data...
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I don't know how you're not having issues
[AT&T Samsung Galaxy S6 Edge] SupahDave:
Are you on OE2? Do you have any apps that are constantly using data? My battery drain wasn't that bad on day 1!
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Yes. Of course I have Apps. Most drain is from the system. I don't have any crazy apps installed. I uninstalled whatever power saving apps I had for aforementioned reasons
[AT&T Samsung Galaxy S6 Edge] Globalrebel:
Grab BetteryBatteryStats to get the wakelocks and help determine the causes. Also, what is your brightness set at? I have mine on auto, and normally get around 2 - 3 SOT and have gmail push done, a few calls, a few texts and a little Nitro racing gaming (about 30 minutes or an hour) with bluetooth streaming on car ride and spotify streaming as well. I get to about 30% by the end of the day before bed. and then I can leave it sitting next to my bed for the entire night and have 25% in the morning ready to charge. I usually don't let it get that low though.
[AT&T Samsung Galaxy S6 Edge] giant420:
I am definitely having issues as well. I have also disabled volte and am only getting about 8 hours of standby battery with 1 hour of SOT. What's odd is there is almost nothing in battery stats.
[AT&T Samsung Galaxy S6 Edge] jaltman:
After you receive the latest update, do a factory reset. My battery life has been great after a reset leaving all options at the defaults. Cache still builds up unreasonably quick and needs an occasional clearing and just doing a restart on the phone also helps. YMMV.
[AT&T Samsung Galaxy S6 Edge] SupahDave:
Agreed. I had battery life problems before the update but since updating and doing a factory reset and wiping EVERYTHING, all is good. I woke up on Sunday and took my phone off the charger and didn't have to put it back on the charger until Monday afternoon and even then the phone still had 35% left (3.5hrs of screen on time)
[AT&T Samsung Galaxy S6 Edge] mchimney:
Hmm, anyone have an issue with google play services taking up most of the battery now?

Google Play Services 16%

Google App 9%

Android OS 8%
[AT&T Samsung Galaxy S6 Edge] arf8:
Same here 35 hours on avg, have not disabled google service and hd voice is on. I have disabled wifi scanning and hot spot however. Battery life is great with mine
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Threre's NO WAY you are even using your phone, lol.

No Nav, no FB, can't be
[AT&T Samsung Galaxy S6 Edge] arf8:
No social media, and I only use the features i need when I need them. I really mainly on email. Some people leave wifi/BT/GPS on all day and wonder why their battery life sucks.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Right, so, you barely use it. Of course the battery life is great
[AT&T Samsung Galaxy S6 Edge] arf8:
I use my phone, i use google maps, stream sling, tivo, security apps, etc, but the key is when you are not using those apps and have no need to keep wifi/bt/gps on, turn them off and you would be amazed how much battery life improves.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I get that, but, that is a huge hassle. I always have some app using something.
[AT&T Samsung Galaxy S6 Edge] arf8:
You have to pay to play, no free lunch. Plus i can't imagine phones where battery life is that amazing with all the radios turned on.
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
I'm going to give this a shot. 3.5 hr SoT isn't bad but it could be way better
[AT&T Samsung Galaxy S6 Edge] eventer289:
Yes, but that shouldn't be a factor. On a $900 phone, we shouldn't have to disable every useful function to ensure good battery life. Other Android phones don't have this level of battery drain with Bluetooth and Wifi enabled. There is an issue with the software which must be addressed.
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
I leave wifi and bluetooth on all the time.

Yes, there needs to be software kinks worked out. All in due time. Just have to wait for the almighty carriers to bless us with it
[AT&T Samsung Galaxy S6 Edge] arf8:
I don't have other android devices, but from what I have read part of the issue is related to lollipop so I agree there are certainly software bugs that can be worked out and hopefully android M aks 6.0 will resolve a lot of these issues. With this phone itself i found a software issue with email notifications that Samsung now has agreed is a problem along with the carrier and are looking into it.

With that said my previous phones behaved more or less the same, when you leave wifi/bt/gps on it does drain the battery b/c those devices are using transmitters/receivers which need battery to operate so common sense tells you there is going to be nominal drain. With my phone I have not noticed unusual drain but i don't rule out some phone have software issues and others don't b/c i proved that with the notification problem itself and OTA update on another phone.

You mentioned other android phoned don't have this level of drain, do you care to share which models and what software they are running and the perceived drain percentage?

Cheers
[AT&T Samsung Galaxy S6 Edge] beartrap:
Bad battery life the last couple of days due to the Smart Lock On-body Detection. Neat idea but it sucks the life from the battery.
[AT&T Samsung Galaxy S6 Edge] arf8:
I also noticed smart stay does the same, turned that off as well. The reality is all these onboard sensors which have to remain active will cause battery drain.
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
I will say that i disabled it when , according to the battery stats page, it was at 13%.

Just checked and that percentage has yet to even change.

This may be a solid fix.

Time will tell. I will report back in a day or so.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I looked at my stats from multiple apps and it looks like the culprit is the OS/System and not a rogue app
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
So after a few days of disabling it, the phone definitely lasts a lot longer which is great! One caveat though, i think by disabling it the LTE speeds drop substantially. I have yet to personally test this so keep that in mind. It just seems that the download/upload speeds are hindered after i disabled it. (Not that i need THAT much down/up for a phone xD)
[AT&T Samsung Galaxy S6 Edge] arf8:
I've ran multiple tests to see if bandwidth is affected and it made no difference, but that is not to say some apps take advantage and others don't. The test was using a html5 site running up/down/response time. If anyone has any more definitive test I would like to see it.
[AT&T Samsung Galaxy S6 Edge] sokar5:
I've got 16hr on battery just by using Greenify app to hibernate my device.

I always have wifi and bluetooth on and connected to my smartwatch. And I figured that watch faces apps run on the background even when I am not using them. So I use greenify to close them for me with few other apps like games.
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
I'll keep your results in mind. I just get an eerie feeling it causes some decrease in down/up

Sent from The Edge
[AT&T Samsung Galaxy S6 Edge] arf8:
I was hoping you were right that is why i went through so many tests but it was clear with the results it has zero bearing on the throughput.
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
I applaud the fact you tested it. I'll accept it as fact and do my best to remove such eerie feelings

I'm more interested in figuring out how to make download booster work at this point.
[AT&T Samsung Galaxy S6 Edge] l Frosty l:
I'm with you there. I just see ATT holding that hostage for a long time.

[AT&T Samsung Galaxy S6 Edge] arf8:
agree
[AT&T Samsung Galaxy S6 Edge] nookie1916:
I have download booster on my atnt edge running a custom rom. That'd be about your only shot.
[AT&T Samsung Galaxy S6 Edge] arf8:
Running? I also have download booster as well but just b/c you have the ability to turn it on and the icon shows up does not mean it works. The issue is on ATT's end not allowing the feature and supporting it. Plus you don't need a custom ROM to get the icon and button to show up.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I have it enabled on XtreLite, and it prompted me that it was switching to 4G when I was streaming video at my hotel on a poor wireless connection. I would assume it's working, but I didn't verify by checking data usage
[AT&T Samsung Galaxy S6 Edge] arf8:
If it is working you will know right away, did the icon light up active when you thought it was working? Also if you drop down the menu you will see the wifi + data usage indicating what portion is allocated to what radio. Also I'm not 100% sure on this but i was under the assumption the download booster only works on Google Play, but that could be incorrect.

A screenshot would be nice. I also assume you are on att and you have a Unlimited Plan? b/c if you don't have a unlimited plan than download booster should work fine. the folks on the unlimited legacy plans don't have the tether option and the download booster is crippled.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Again, I didn't verify. I was watching the video and noticed the toast. I'll check next time. I do not have unlimited data

I do have a new icon where the wifi icon is
[AT&T Samsung Galaxy S6 Edge] arf8:
When you get a chance post a screen shot.

If it is working you should get this when you do a pull down.

[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Yep. It works
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Doesn't make sense that they wouldn't enable it. It would just make them more money with data overages
[AT&T Samsung Galaxy S6 Edge] arf8:
Nice, must be something in Cleanrom that allows it to work, b/c the factory rom with it enabled does nothing. Not sure if legacy plans have anything to do with it either.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I'm not running clean. But, I saw another thread that some other feature only worked on custom ROMs. Must be the same case
[AT&T Samsung Galaxy S6 Edge] arf8:
Forgot you are on XtreLite, I'm going to see if there is an apk i can extract to get it working on the stock rom. If i didn't care about knox i would change rom but for now root gives me enough options to tweak for my needs but the download booster is a nice option to have working on factory rom
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I flashed with flashfire. Didn't trip knox, did lose GPS l, but other than that it's great lol
[AT&T Samsung Galaxy S6 Edge] arf8:
Nice, the lack of GPS is a problem for me. I have the stock ROM so modified already i don't even want to start over plus I'm sure others like myself would just like it working as it. If there is a way to extract the apk or the download booster zip and flash that would be ideal. I'll have to do some digging.

cheers
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
It's a problem for me also, but, not having an SD card and having to move stuff back and forth from my PC takes several hours, and the dev is supposedly releasing the fix in next release, so, I wait...no time to go back to stock and I lose other features
[AT&T Samsung Galaxy S6 Edge] arf8:
I hear ya, might be worth while getting a NAS to have it sync over wifi when you get home.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I do that with Sweet Home, but that only does photos. Is there another app that will sync all device changes across a network? The other issue is I travel 5 days a week and I'm home 2. I'm usually on the road more than I'm home
[AT&T Samsung Galaxy S6 Edge] arf8:
Look into Synology NAS and build in Cloud sync, does exactly what you want. Also don't forget to setup a VPN.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
Yeah. That's one way to do it, but, not looking to drop that much on a NAS. I'm an IT guy by trade and have a bunch of boxes around as is. I could probably make it work. Just have to dig around and take the time to do it, haha
[AT&T Samsung Galaxy S6 Edge] mj0528:
I'm so close to taken this thing back. I've tried everything short of a factory reset. Without autostarts working, it's hard to get the deep sleep like you can on just about every other device out there. Is there an autostarts alternative? Are there any other suggestions to rectifying this battery drain issue outside of everything that has been mentioned here. Couple more days of this and I'm done. I came back from IOS world (iphone 6+ where a battery charge would easily last 2 days with heavy use. Now i'm charging every chance i can get. I just don't think it's worth it. What other top performing android phones are suggested? I had the HTC m8 so i don't think i want the m9. The g4 is still out to court in my mind.
[AT&T Samsung Galaxy S6 Edge] arf8:
The biggest drain is apps running in the background. You need to debloat. I'm at 1.5 free ram on stock Rom rooted. I spent 1 hour and 10 mins on a phone call on hold with the screen off and my battery was still at 99%.
[AT&T Samsung Galaxy S6 Edge] dirtyballoonot:
I've had every galaxy since the first with exception to the 5, which actually had decent battery life. They all suck if you use your phone. I've never gotten more than 8-12 hours of heavy use unless you severely limit functions (WiFi, GPS, BT, social apps), but, if you do all that why even own a smartphone? I'd rather stay tethered all day than go back to iOS

With that said, you can try an app like Trigger that turns radios on and off given certain scenarios
[AT&T Samsung Galaxy S6 Edge] Globalrebel:
Ok . . . I want to know what apps you have installed and how you are managing them. Cause that is just insaine! I have full (4 bars) LTE at my house and I can't even make a call for 30 min without my battery dropping more then 15%
[AT&T Samsung Galaxy S6 Edge] mj0528:
so my main culprit after blowing it away and starting from scratch seems to be facebook. I've turned off all notifications but it still keeps my phone awake the entire time it has my account info in it. When i was rooted and used greenify to hibernate system apps, it was the same.

It seems that some of the things i remember from android a last year is different at least with this phone anyway. No autostarts or wakelock app to see exactly what is going on.
[AT&T Samsung Galaxy S6 Edge] arf8:
Here is what I have running after boot, mind you i don't use social media nor do i keep radios on unless i need them. The only radio that is on 24/7 is the mobile network that is it, the rest i turn on and use as needed. I'm not posting my disabled b/c i deleted some of the bloat so it won't even show up.

One important thing to understand is Li technology. I only charge at < 1/2 x C while most charge at 1C or greater, understanding Li technology goes a long way to preserving your battery in the long run. As an Engineer I've done a lot of research on this subject so I'm a little more informed then most but the information is out there and its nothing new, even Tesla employes the same principles on their cars b/c their chemistry is very similar to our phone battery.

[AT&T Samsung Galaxy S6 Edge] mj0528:
how do you charge at < 1/2 x C?
[AT&T Samsung Galaxy S6 Edge] arf8:
1C is 2.6A , 1/2C is 1.3A if you wireless charge or use a 1A charger you are charging at < 1/2C
[AT&T Samsung Galaxy S6 Edge] mj0528:
Got it, thanks!
[AT&T Samsung Galaxy S6 Edge] arf8:
No problem, if you do a search on Li batteries and C rating there is lots of info out there.

cheers
[AT&T Samsung Galaxy S6 Edge] Globalrebel:
I bet that is why i get a better longer lasting battery when I charge uysing my 1.15 A overnight rather then the fast charger.

I'n only going to use my 1.15 from now on unless I'm running late and need at least a decent charge.
[AT&T Samsung Galaxy S6 Edge] arf8:
Li cell degradation is fascinating, my advice for better battery life is to reduce the bloat and use the radios as needed. How you change your new battery now will not impact your immediate issues with how long your battery lasts but in the long run it pays dividends to understand Li technology, especially since to remove and replace the battery in the s6/s6e is much harder than other sealed phones, specifically the s6e.

good luck
[AT&T Samsung Galaxy S6 Edge] Globalrebel:
Just wanted to post out here that my last charge cycle with same usage was much better since switching to only using my 1.15A charger. I'm also more conscious of my radios, but I thought I'd share :)
[AT&T Samsung Galaxy S6 Edge] Tactical911:
Hello guys,

I created an account just so I can add my "name" to this lovely battery drain list problem. First off I would just like to say that I have followed and done the guides on page 3 and page 8 post "76". So far nothing seems to be helping. Phone is sucking the battery like nothing else I have seen.

Basic background on phone and Usage.

-AT&T Galaxy S6

-All "Radios" are turned ON

-Usage is mainly Bluetooth headset, litsening to podcasts or music.

-Every now and then pick up the phone, check a game out / email / Web. Then place it back down locking the screen.

-Recently been using Clean Master, and I have also disabled "TouchWiz" (as someone said it was a battery hog) Using another launcher "EverythingME"

-Basically nothing has change, Battery still sucks.

Here are a few pictures.

apologies, xda forums wants me to post at least 10 times before being able to post links. copy and paste the flic.kr address to your bar and it should work.

"Before any modifications"

flic.kr/p/z3uDBF

"After modifications on pages 3 and 8, and launcher"

flic.kr/p/z3uDCc

"Todays Performance"

flic.kr/p/z3uDD4

I really am stunned with the battery performance of this phone. Especially coming from an Iphone 6plus where my phone usage was just the same as it is now, only major difference is at around 5pm I would still have like 45-50% left on my Iphone. I have no interest in turning this thread into a Samsung / Iphone debate, I'm just simply stating my personal experiences.

I'm hoping either someone comes out with another guide that works, or that At&T or Samsung patches this issue.

-Mike

I'm getting great battery since I did the update to 5.1.1.

[AT&T Samsung Galaxy S6 Edge] Tactical911:
Hello Dra444,

Indeed some people are reporting excellent battery usage, which is crazy.

I've done now several tests and taken several pictures, I been charging the phone to 100% at like 11pm , closing down ALL runing apps with "Clean Master" and then locking the screen and setting the phone in my stand until like 6am, Without even touching it or looking at it. At 6am the battery is 58%, How the heck is it using almost HALF the battery while the screen is locked and the phone is not even being used.

ALSO, these battery analytics are bulls**t, they might as well not made anything. It tells you absolutely nothing.

People are upset about Volkswagen bending the numbers on its fuel consumption, by up to like 40%. The same point could be argued here.

but anyway below are the pictures.

Reminder that xda forums does not let me place links until I have 10 posts, please paste the address below to your URL bar, it will work.

Reminder: These are tests being conducted throughout the night! the phone is getting NO use. It is just sitting there, looking pretty with the screen locked.

I was also having a fairly serious drain after updating to 5.1.1, now it wasn't as bad as yours but it was still about 25% overnight. I finally caved in and did a factory reset and then manually reinstalled and setup everything again. With Enhanced LTE enabled I had a 13% drain overnight and while I found things much better I still ended up disabling Enhanced LTE as at times it would cause a big drain, mostly when I didn't have LTE coverage. I'd recommend you try that and then set everything back up and see if things are improved.
[AT&T Samsung Galaxy S6 Edge] Tactical911:
Hello there dpw2atox,

Actually I had enough of this issue, So yesterday afternoon I went to an AT&T store. They told me to take it to a special Diagnostic AT&T store, they hooked it up to a diagnostic device and the lady did tell me that the battery was "fine", However she did notice that on the back of my phone it got hot. (It always got warm/hot ever since I had the phone.) She then turned it off, turned it back on and it started to get warm/hot again.

So she told me she they were going to replace the phone, So I should be getting another Samsung Galaxy S6 within a couple of days.

Maybe mine turned out to be just a defective device? I can't really speak on the warm/hotness that the phone gets on the back. This is my first Samsung phone, anyone else who has this phone does it usually get warm/hot on the back of the phone, center of the phone just below the camera lens and then it moves to the sides of the phone the "metal border".

Once again just for giggles, I charged it again last night to 100% and when I checked it this morning it was at 49%.

This is with the following.

[ ]Enhanced 4G LTE is OFF

[ ]Always Allow Scanning OFF (advanced wifi settings)

[ ]I have set my emails to sync every 12 hours! (which is ridiculous, but i thought i would try it.)

[ ]All radios enabled, Wifi - Location - Bluetooth

(to the people that will say, turn OFF your radios. since your not using the phone through out the night. Valid point, however i'm sure we can all agree that 40-50% of your battery should NOT be used while the screen is LOCKED and the phone is sitting on idle.)

Other stats based on "Clean Master"

33% Sotarge, which wont matter.

74% RAM being used. I think this is way to high

But anyway, anyone that may be having this issue. Try taking it to a Diagnostic store and let them run a check, and see what they tell you.
[AT&T Samsung Galaxy S6 Edge] Dra444:
Yeah definitely something is wrong with your phone. I'm getting 4 hours and half screen time on mine. I used my phone playing clash of clans and a bunch of chatting with whatsapp. Way much better than before I did the update. So yeah let them replace the phone.
