Forgive me if I haven't kept up with or read over this whole thread. It's quite lengthy.

My battery has been pretty decent. Not great, but decent. I was disappointed Friday night when I left it on the wireless charger all night. It hit 100% and then stopped charging. In the morning, once I checked it, it was at 64%. I was disappointed that it would drain 36% in 10 hours. Then came last night. I had it at or nearly at 100% and took the phone to bed with me to serve as my alarm clock. This was around 10 PM. At 4:40 AM, my phone made the loud chirping noise that I've come to associate with my battery dying, and it was at 15%. I put it into super power saver at that point. How on earth did it drain 85% in less than 7 hours?

[Galaxy S6 General] tiatmed:
Just wondering, is it fine to leave it charging overnight?
[Galaxy S6 General] pnr2020:
It's fine they automatically stop charging at 100%
[Galaxy S6 General] Japultra:
I just downloaded and checked and yes, I do go into deep sleep. As of right now I'm at 80% battery with 59% deep sleep. Strange that I would go from 100% to 97% in less than 2 hours with only 2.5 minutes of SoT. Very used to the standby time on my G3 which would basically stay at the same percent for hours when I don't touch it.

Have you checked Gsam or BBS?
[Galaxy S6 General] Biggenz:
I think the more apps you install to check phone/battery status, the more it will drain your battery. All I did was disable all the Samsung bloatware, used a 3rd party mail app as I prefer it and the stock mail app was horrendous on battery drain, and I have amazing battery life. Couldn't be happier.

Also, instead of using the supplied fast charger, I use my Samsung Galaxy camera's charger as it's a 1A rated charger rather than 2A. It can't be good for the battery to be put under so much strain every time you charge it. Seems to do the trick for me!
[Galaxy S6 General] flu13:
I'm not familiar with those. What do they do?
[Galaxy S6 General] Japultra:
It tells you which apps are using your battery so you can pinpoint which one is sucking you dry.
[Galaxy S6 General] flu13:
Ok, I'll give that a try. I figured that's what the Battery display was telling me, but apparently not, since it didn't have a smoking gun in there.
[Galaxy S6 General] tiagovale2:
It is. The only real caution you need is to try not to let it go under 15%. Aside from that, use and abuse.

Just gave Samsung a call about the cell standby issue and was told that it is a feature. I explained how rapidly my phone's battery would drain idling and apparently it's supposed to do that. Yay.
[Galaxy S6 General] Japultra:
The Android one isn't very good tbh. Most of the time it's very inaccurate.

---------- Post added at 03:54 PM ---------- Previous post was at 03:53 PM ----------

A feature? For WHAT?
[Galaxy S6 General] sdesmore:
Does battery life get better the more you charge this phone? I'm getting 2 hours sot at the moment. Fully charged at 8 AM, it's now 5:22 PM and got 20 percent left. All updates completed. Have the phone for 2 days...
[Galaxy S6 General] pnr2020:
That's terrible battery life try freezing stuff you don't use it helps a lot.
[Galaxy S6 General] tiagovale2:
It usually does, yes.

Isn't Samsung Push Service required to get notifications?
[Galaxy S6 General] pnr2020:
Only for Samsung apps like s health or s planner
[Galaxy S6 General] belloni:
The main thing keeping my phone awake on apps is "Mobile Active Radio", does anyone have a fix for this? I'm going to do a complete wipe tonight on TWRP, internal included and start afresh.
[Galaxy S6 General] Clay330i:
What 3rd party mail app do you use? Is it just for Gmail or does it support exchange as well?
[Galaxy S6 General] gigoypotpot:
Hi i just checked that my phone is deep sleeping 65% since last charge. Thats good, right?
[Galaxy S6 General] pnr2020:
Yep that's good
[Galaxy S6 General] Sevael:
S Planner notifications still work with the push service frozen. I think it's more for updates to Samsung apps through the Galaxy Apps updater.
[Galaxy S6 General] belloni:
I've just re done my phone from scratch, and I'm still getting the above drain. Can someone please help or I'm going to have to get a new phone.
[Galaxy S6 General] ramon.nmgn:
Actually very satisfied here!

Battery holds about 1.5 day. Getting up at 07:45 am. Battery dies next day around afternoon.

With that, i always have a +/-4 hours screen on time
[Galaxy S6 General] pnr2020:
Same here I'm getting great battery life nearly 5 hrs screen time and still 39% left
[Galaxy S6 General] Billchen0014:
My battery dropped by 15% overnight, not even know why... :(
[Galaxy S6 General] smooth4lyfe:
What carrier are you on?

Make. Sure HD Voice or VoLTE is off if you are on AT&T... that's what helped my overnight drain

Sent from my Samsung Galaxy S6!
[Galaxy S6 General] ronnienyc:
SPTINT s6 here...battery much improved.

My phone has no drain issue. However battery life has not been stellar.

UNTIL:

Yesterday I turned WIFI calling off (and deactivated some bloat). And today I am at 46% battery life at 4:04 PM, and this is with 3:24 on-screen time. I was not even close to that before.

Before this I was getting maybe 3-4 hours screen time total in a day before dead battery.

Now, I am not sure if the improvement is due to my changes or not...but I suspect is has a lot to do with turning off both WIFI calling & Location History. WIFI calling seemed to be pinging wifi non-stop while it was on. My Held-Awake stat is now at 1%.

FYI I seem to be getting around a 7% drain overnight (9-10 hours overnight standby).
[Galaxy S6 General] Billchen0014:
I'm on Telstra in Australia, they don't have HD voice nor Voice over LTE I think. Greenfying tonight see if that helps.
[Galaxy S6 General] Alfa Kenny One:
For me battery life is good for one day. Moderate usage; internet, WhatsApp, poweramp, email.

For me Just perfect
[Galaxy S6 General] mmmihhh:
I am very happy with my edge battery. I live in Canada and I'm on Bell. I don't use power saving, I have 3 email accounts that sync every 15 min, wifi and location always on. I was using skype video calling, moderate phone calls and messaging, whatsup, app instalation etc and here are my screenshots. This is after my first charge so the battery should increase.
[Galaxy S6 General] cheetah2k:
My biggest issue with battery drain is the constant "mobile Radio Active" chewing up the battery in Andriod OS and in particular, Facebook. My facebook mobile radio active on time is in excess of 5 hrs a day, even though I check FB first thing in the morning and then, at lunch, and then again when I get home. For some reason its on all that time. The only way I can stop it is to force close the Facebook App.

All that aside, with my usage I get around 4.5-5hrs SOT. The best I had the other night down to 3% left was 5hrs 29 min but I did not use Facebook the whole day
[Galaxy S6 General] elbos2k:
In the Facebook app go to App Settings- Messenger Location services and disable it. Also check the sync settings for the Facebook app under Accounts...
[Galaxy S6 General] krusty_dc:
Coming from a very bad phone in terms of battery life (htc one x) the Galaxy s6 is almost comparable to it when in comes to my every day usage. I like this phone but very disappointed with the battery life.
[Galaxy S6 General] apsis:
A lot of drain here today. But still some great battery life for the fact that is almost two days off the charger. With WiFi, sync, auto brightness, lte connectivity.

Gonna install the Google play services update now and will see if the drain goes away. [emoji4]

Quite impressed from the phones battery life
[Galaxy S6 General] 220volt:
Were under account do i find sync settings?
[Galaxy S6 General] elbos2k:
Go to Settings-Personal-Accounts. You will see all apps that use syncing. Just uncheck whatever you don't need...
[Galaxy S6 General] cheetah2k:
Awesome!!

Thanks mate I'll give that a go :good:
[Galaxy S6 General] kojaraty:
You are getting good battery life. You can get more than 5 hours SOT if you countine using the phone the way ur using it at the moment.
[Galaxy S6 General] krusty_dc:
IDK. Coming from a 3 year old phone the battery life feels the same. The screen shot above has all the Sammy apps disabled and some gmail apps disabled also. Location is turned off and on power saving mode. I do feel the battery is a let down.
[Galaxy S6 General] MakoVince:
I seem to be getting some pretty decent drain here. I'm not coming anywhere close to what you guys are getting. I would kill for 5 hours of SoT.

I'm only at 1:12 SoT and already at 60%. WiFi and Bluetooth on, location on, GPS off. Brightness at 25% with auto on.

[Edit] I've installed the new Play Services package
[Galaxy S6 General] belloni:
Anyone?
[Galaxy S6 General] majid25:
Battery is great so far, was getting 8 hours of use but after a factory reset things have been a lot better. It is possible the update Samsung put out is helping but either way I am very content with the battery of this phone
[Galaxy S6 General] Biggenz:
I use Type Mail(formerly Blue Mail). It's an amazing mail app and by far the best I've used. And I've tried them all!
[Galaxy S6 General] sdesmore:
Same here, getting 1.5 to 2 hours SOT. Don't have many apps installed. Already tried factory reset, don't know what to do.

Yesterday fully charged my phone before i left work, at 5:30 I had 15 percent battery left. Very poor!!! miss my G3 already, battery would easily last 24 hours
[Galaxy S6 General] Japultra:
You appear to have very good battery life. What exactly are you disappointed about?
[Galaxy S6 General] krusty_dc:
Honestly I still don't know what to expect with the battery life of this phone except not to have the same as my old phone but apparently it is almost the same. I know you guys might have the s5 or s4 to compare with I only have my htc one x.

Overall I am satisfied except for the battery life.
[Galaxy S6 General] Japultra:
Compare what you're getting with what other people are getting and I'm sure you can tell you get extremely good battery life. From the screenshots you posted, it looks like you could easily reach 1.5 days of battery with about 5+ hours of SoT. Ask anyone here and they'll tell you that's very good!
[Galaxy S6 General] krusty_dc:
Thanks for the confirmation that I dont have a busted battery. I guess I'll just have to adjust the usage to the battery life.
[Galaxy S6 General] Japultra:
We can trade battery life if you want! Would love to get what you're getting :D
[Galaxy S6 General] krusty_dc:
These are the disabled apps that I have. Just browsing to Chrome with xda drains 8% battery for 25 mins SOT. Power save is on.
[Galaxy S6 General] Japultra:
Ah, no wonder you're getting great battery life. Are you also rooted?
[Galaxy S6 General] krusty_dc:
Nope. Not yet. I'll check next week for a good custom rom.
[Galaxy S6 General] tiagovale2:
Currently with 64% left, 1h30 screen on time, 13h since off charge.

WIFI, 4G, adaptative brightness, fingerprint unlock and smart lock always on.

Pretty good, I'd say.
[Galaxy S6 General] KingFaisal:
I disabled everything and made this a phone from 2011. Here are my results.

I think I fixed google services when I set play to never auto-update (or it was the reboot).

Today I got 4h30m. I only dare use Spotify when I have a charger available (like in the car).
[Galaxy S6 General] jntdroid:
Perspective?

Can someone help me out here...

When I'm using my iPhone 6, I hardly think about the battery life. We have lighting cables all over the place, and all I do is plug it in if I see it's getting lower. I know that generally speaking I don't worry or think about it, even though I know the battery life on it is just pretty good - not great but not bad.

Why in the world do I obsess over the GS6's battery life when I know it's similar and charges even quicker? Is it just b/c there are XDA threads to enable that obsession? ;)
[Galaxy S6 General] megagodx:
There's mine.
[Galaxy S6 General] meboy:
Not enough info to help.

Did you root? Install twrp? Re-flash recovery after twrp? Did you check that it's going into deep sleep with cpuspy?

These steps keep getting mentioned. This is the first thing to look at if you have drain.
[Galaxy S6 General] belloni:
I've rooted and installed TWRP. Shall I flash stock recovery? My phone isn't entering deep sleep at all on CPUSPY.

I have a SM-G920F UK Samsung S6, where can I download the stock recovery?? Is a stock recovery same as a stock firmware?
[Galaxy S6 General] meboy:
Yes. Flash your stock recovery.img

There is a link in the General section sticky at the top of the page. But here is the link.

http://xdaforums.com/galaxy-s6/general/stock-firmware-official-stock-firmware-t3086387

Extract the recovery.img from the ROM just like you would unzip something. First unzip you will get a .tar file. Second you will have the actual folders/files and can find the recovery.img in there.

You can just use Flashify from the app store if you like. Or Odin.

You should be good with deep sleep after that.

I just made a thread about it. Hopefully people see it and use it.

How to Fix Battery Drain after root/twrp
[Galaxy S6 General] ronnienyc:
I turned wifi off overnight and went from 7% drainage to 2% drainage while idling for 9 hrs overnight.

By turning off wifi (and of course wifi calling) my battery life has gone from bad, to now approaching my Note 4 in terms SOT (5.5 hours yesterday) and 2% overnight drainage.

(Since I have unlimited data I suppose I can leave wifi off until a wifi fix comes about.)
[Galaxy S6 General] microserfs:
I'm struggling to understand why some days with this phone are better than others. Today after taking it off charge I dropped 10% within 2 hours of doing absolutely nothing. Now after using the phone for a 20 minute phone call, some photo taking and some browsing and FB usage it's hit 79% with only 51m screen on time.

Other days Ive found it slightly better. GSAM is still telling me Android OS is the highest percentage of battery usage. Not sure whether it's just a Lollipop issue but even so the percentage listed for Lollipop UI was 1.1%.

I'm too late to return it now as I've hit the 2 week mark and I love this phone too much to get rid of it but I'm still pretty disappointed that one minute it's looking more promising then the next it's falling short of anything remotely decent.

Guess I could always factory reset but I've already installed so many things to the phone I don't want the hassle haha.
[Galaxy S6 General] stratplayer:
My results today. Personally I think they suck. Only had a few minutes of calls and not much screen on time
[Galaxy S6 General] Japultra:
I agree. That is atrocious battery life. Do you have weak signal where you are at?
[Galaxy S6 General] assasin34:
i got rid of my s6 after 10 days usage.i cant stand this in 2015.returned to my iphone6 plus.
[Galaxy S6 General] LoverOfTech:
Have had my UK S6 for just over a week and battery life has been great for me. Getting 1 and a half to 2 days easy. This is running it to around 20%. Once charged up I get this
[Galaxy S6 General] Aircondition:
How did you revert from absolute battery percentage use back to normal ? I know this is somethnig that got changed in lollipop and its confusing me.
[Galaxy S6 General] tiagovale2:
In battery settings there is a "hide percentage" option.
[Galaxy S6 General] elbos2k:
Seems like I found another potential battery draining "bug". Go to Settings- Lock screen and security- Other security settings- Security policy updates- and turn those options off. I seem to be getting better battery and stand by times as well....
[Galaxy S6 General] ronnienyc:
Wifi on or off? Tried turning wifi off like I suggested earlier? Or alternately just turn wifi calling off?
[Galaxy S6 General] Jarrive:
Guys, all of you are struggling to cut there and there some software, so disable all you can, to use different solutions to observe the battery life, the drainage, etc. It is worth it? What is the purpose of all that technology if you can't use it as you please for at least 12 hours in continuos mode? On a short term, maybe you will be satisfied, but consider this mater after 6 months or 1 year! The main problem of this phone is the screen. It is using too much power. There is no solution to fix it. Not on this device. The only solution is to refuse of accepting this behaviour from Samsung. I returned my S6, and i will not buy again this product.
[Galaxy S6 General] Gboss01:
I disagree with your statement on the screen. I think this screen is very efficient. By my own experience and observation the S6 screen uses less power than the S4 screen.

On my S4 the battery dropped way quicker when having the screen on browsing the web or watching videos than my S6.

Im getting great battery life without crippling the phones functions. I have simply removed any of the apps i dont need.
[Galaxy S6 General] jasonm253:
So far after rooting, installing the xsterolite rom (tmobile), wipe cache and davlik. This has been the best battery life I have had so far By this screen shot. I keep my twitter (fenix) connected so it took up some drainage.
[Galaxy S6 General] belloni:
Finally fixed my battery drain I think. I'm rooted and was never entering deep sleep, so flashed stock recovery and now it deep sleeps perfectly. Will report back any changes
[Galaxy S6 General] Slicktune:
Nice, what was your screen on time tho? And how is the standby drainage after she before rooting? Thanks in advance bro!
[Galaxy S6 General] MysteriousDiary:
I'm very happy with the battery life since I've disabled two Google things - Google Now and the Google Smart Lock. I think the last one was my biggest issue with its trusted home zone feature. Since I've disabled the Smart Lock in the Trusted Agents settings my WiFi uses much less battery.

I would always try to search the problem in the apps you've installed, an old backup or the Google apps first. Those are the ones Samsung can't control and can't be well tested. In another forum many could also fix their battery issues by disabling some Google features - it looks like Google needs to fix some bugs in their apps.
[Galaxy S6 General] KingFaisal:
Seems like you used the phone continuously for that time. What were you doing and 4g or WiFi?
[Galaxy S6 General] gigoypotpot:
Where exactly is the smart lock feature? I'd like to disable it muself even though I have been getting great batery life.

That's to be expected when using HSPA. LTE is very inefficent. I may set the radio to only use HSPA. I barely notice a difference.

[Galaxy S6 General] RonSwanson21:
Ok so I've got an international 920F and I've been experiencing the worst battery life ever since I got the phone. 7 to 9 hours of battery life in total and never more than 1.5 hours of SoT. Now, one of the biggest battery hogs I saw in my stats was Google Services. Yesterday, Google released a Google Services update which made the S6 compatible with Android Auto and I'm willing to bet that they also fixed a bug which wouldn't allow the phone to enter deep sleep, because suddenly since yesterday morning, battery life for both me and a friend who also has an S6 shot from +-7 hours right up to 15 hours with 3 hours of SoT. Neither of us had made any changes to try to improve the battery life in the last 2 days and both of us experienced this and as we know, Google releases silent updates you have no control over. So quite a coincidence, me thinks. Hopefully those who are also having major issues with battery drain are starting to experience some relief
[Galaxy S6 General] KingFaisal:
I had issues with Google Services. I solved it by setting Play to never auto-update and also rebooting the phone.
[Galaxy S6 General] Wiggz:
In this day and age it STILL astounds me that the solution to crippling battery life (not saying the S6 has it currently - still testing my new device) is to turn off the very features that made you purchase the device.

I want my WiFi on all the time as mostly, I'm connected to an access point at home when working. I "could" turn GPS off, but I didn't find this to drain the battery much if left on without an application using it anyway.

Turning off data when the screen is off.....just NO. I'd wager more than half of the notifications that users get now are via mobile based data connections...so your "smart" phone becomes Dumb quite quickly.

Users want good battery life but not at the expense of the USPs that drew them to the device in the first place

Stop and think before commenting?
[Galaxy S6 General] Jarrive:
I have the same opinion about batteries. I returned my 64G S6 for this reason. I don't understand why they fight for slimer body, low weight device and a battery life enough to last 2 hours. The basic of mobility is power. That's it!
[Galaxy S6 General] Wiggz:
Perhaps my issue is that I'm coming from a Droid Turbo which had a 3900mAh battery instead of nearly half that!
[Galaxy S6 General] mcreego:
two full days of powerful use with XtreStoLite rom. Better then my iPhone 6 and Note 4. In the beginning I never reach the evening...

Very satisfied.:D
[Galaxy S6 General] KingFaisal:
I want to root and experiment, but Samsung Pay was one of the features that made me buy the phone. Also, I still have 4 days to return and I don't want to risk my return by tripping Knox.

The battery life is tragic. However, the screen has spoiled me......
[Galaxy S6 General] FlowingAway:
Ok so I took the phone off of charge once it hit 100%. In 3 hours my battery dropped 3%. 65% deep sleep according to cpuspy. Android system and kernel were the culprits for the 3% drop and seem to be the culprits for all my battery drops (besides screen).

Is this good battery life? I feel it's not terrible but could be better based on what I've seen here. How can I keep android system and kernel from draining so much? Just factory reset last evening and installed back some apps but made sure not many of them are set to push notifications and such.
[Galaxy S6 General] KingFaisal:
Ok

3 hours screen on time is poor battery life

4 hours SOT is average

5 hours SOT is good

6 hours SOT is amazing and very difficult to achieve

4-5 is where most people are. I personally get 4.5 hours of screen on time with 26 hours of total off battery time (I slept after hitting 100% and unplugging).

EDIT: Atm I have 4 hours of screen on time, 19% remaining with 23 hour on battery.
[Galaxy S6 General] crazynarutoman:
Good or Bad Battery Life?

Can't tell if this is good or not...coming from a Nexus 5 that was tweaked for max. battery life, I feel like the S6 is a bit disappointing. I consider myself a power user, with Facebook, Instagram, Whatsapp, KakaoTalk, Reddit, and Snapchat running. Not all the time, but I check them fairly frequently. I also listen to music a lot. Completely stock, I feel like the battery life should be better. Any tips? Should I root and install Greenify? Holding off on rooting atm...scared of needing warranty.
