The problem doesn't seem to be SOT, but standby time. When I use the phone for an extended period of time, such as when I'm in bed for an hour, I only loose a few percent. However it seems to drain nearly as fast when it's in my pocket. This is why some get 5 hours of SOT while people like me who dont use it much are lucky to get 2 hours. Standby time seems to max out around 12-14 hours.

Yep I noticed this, got mine yesterday and to sleep at 89 percent woke up at 79. Lost 10%. Hopefully an updates helps because while in use It's fine.
[Verizon Samsung Galaxy S6] GolferChris68:
My Verizon S6 (64GB black) also has Cell Standby as the number one drain on the battery. It's significant compared to my Note 4, where Cell Standby is much lower on the list, and which loses a lot less battery power when idle compared to the S6. Doing a full factory reset, wiping cache doesn't change this fact on my device. Good to see that others have this issue, though I wonder if Samsung/Verizon will really do anything to address it. I love some aspects of the Galaxy S6, but the battery life is an issue for me.

---------- Post added at 10:16 AM ---------- Previous post was at 10:01 AM ----------

Yeah, this is exactly what I see. My S6 lost 11% of battery as it idled while I slept, with Cell Standby as the largest user of battery (by far) during that time. It has to be a bug, as my Note 4 (with Lollipop) doesn't have this issue.
[Verizon Samsung Galaxy S6] jntdroid:
So my first two cycles on Friday and Saturday were pretty normal and the phone idled incredibly. Then all of a sudden the last couple of cycles (and this one I'm on now apparently) are being killed by Google Play Services, even while idle. I hate that app (not really). I wish it was more clear what within it was eating up the battery.
[Verizon Samsung Galaxy S6] ozv101:
My experience: Got a S6 Edge from Verizon Apr 10. I was having data issues where I couldn't load pages even though it said 4G. My Cell Standby was pretty high 30%-40%. I was attributing the poor reception to the Cell Standby. They finally gave me a new phone yesterday. The data issue was fixed but my Cell Standby is still high at 30% (I turned off Advanced Calling). I'm assuming this isn't a hardware issue unless I'm really unlucky.
[Verizon Samsung Galaxy S6] steelersmb:
I wish I could figure out what is killing my battery. I have done everything and I still can only pull out about 2.5 hours of OST if I am lucky. There isn't really any apps that seem to be sucking the battery except that Android System is always the highest one on my list. The Kernel is next but after that everything is very minimal.
[Verizon Samsung Galaxy S6] jinforthewin:
Same here. Went for a hike today with a buddy that has a note 4. I enabled power saving mode. Not even 2 hours into it and I was at around 37%, granted I did take some photos and was listening to a podcast. But Cmon!!
[Verizon Samsung Galaxy S6] krypto1300:
I'm having the same issue on one of my S6's, I have 2 setup pretty much identically. I read somewhere that a factory reset without restoring from a backup is working for people. I'm going to try this next.
[Verizon Samsung Galaxy S6] :
Try flashing the stock tar file from here. I did it when I first got the phone because my benchmark was low and that brought it up where it should be. When you first flash it the custom logo will appear and when you reboot it will be back to normal. It's an official Samsung tar so there is no worry about tripping Knox or voiding your warranty.
[Verizon Samsung Galaxy S6] krypto1300:
That's a great idea! Thanks! Do you think restore would be safe?
[Verizon Samsung Galaxy S6] supersmash19:
I think I'm going to try this as well because my benchmarks come up at 56k (still good but most others report around 70k) I know benchmarks don't matter but if a factory reset will improve performance then I'm all for it. I really wish I did one right when I got it though because deleting everything is gonna be a pain especially without titanium backup for app backup.

Try the link I have to Samsung Smart Switch. Make sure you get the one for the PC, the app for the phone is useless unless you are switching a device. It restored all my apps and internal storage.
[Verizon Samsung Galaxy S6] Wrw311:
Still struggling on my end

I've done a full wipe, played around with the settings and still have no luck. Last night I had my phone on the wireless pad I have. I'm not sure what happened but I woke up and the phone was dead. (it was on the pad perfectly fine before i went to sleep, didn't appear to be moved at all) Looking at the battery stats, i have 75% cell standby as my phone is on wifi at all times at home. I might try flashing the stock if that appears to be helpful for some people.
[Verizon Samsung Galaxy S6] Gizmoe:
If it's that bad you need a replacement. This is not normal behavior. If I set my phone down at night and forget to plug it in it has almost the same amount of juice when I wake up. The battery life on these are not fantastic but it's better than my htc one m7 with 10x performance so not bad IMO.
[Verizon Samsung Galaxy S6] Wrw311:
You can see around 9pm or so I plugged my phone in, took it off around 10, then you see it start to charge again around 11pm when I went to bed (this time on a wireless charging pad). All of a sudden it stops charging, drops and dies.
[Verizon Samsung Galaxy S6] Gizmoe:
Yeah that cell standby is crazy. Not sure why some phones do that and others dont. Its a problem though. You can see on mine android system is at top and cell standby is below at only 3%.

---------- Post added at 09:09 AM ---------- Previous post was at 08:46 AM ----------

Have people with bad cell standby tried unchecking all the boxes under advanced in wifi. The always scanning thing seems to fall under cell standby category. I have mine off and it does not effect my device signing onto known wifi networks when in range. Also the popups are just annoying.
[Verizon Samsung Galaxy S6] krypto1300:
Well this fixed my other S6. Odin back to stock and set it up as a new phone. Now I get 1 day and 17 hours stand by.

Thanks for this!!!
[Verizon Samsung Galaxy S6] steelersmb:
I tried this several times and can't get it to work. It's keeps failing saying Re-Partition operation failed.
[Verizon Samsung Galaxy S6] :
Try Odin 3.9 and just use the AP button and the default settings. I'll update the OP with a link to Odin 3.9 as well.

EDIT: If all else fails use Samsung Smart Switch for the PC.
[Verizon Samsung Galaxy S6] steelersmb:
Thanks for trying but that didn't help either. From what I've read, it's something to do with the PIT file.
[Verizon Samsung Galaxy S6] :
That's odd because the tar file is directly from Samsung Smart Switch and 100% official for the VZW S6.
[Verizon Samsung Galaxy S6] steelersmb:
I may try it on another computer tonight when I get home to see if that's causing any issues.
[Verizon Samsung Galaxy S6] bulltproof:
I hate the S6. Hate it. The battery has to be charged twice a day. I get 2 1/2 hours SOT on a charge. I have gsam installed nothing out of the ordinary shows up.

I also get constant force closes from different apps.
[Verizon Samsung Galaxy S6] Gizmoe:
I've never had a single force close.
[Verizon Samsung Galaxy S6] Erasmus354:
My phone nuked itself the other night. Went from 80% to completely dead. I changed the WiFi settings to only be on when the phone was awake or plugged in. It did not do it again so far, the cell standby has gone down dramatically. I also turned off the google scanning of wifi.

I think the cell standby issues are all caused by the WiFi radio.
[Verizon Samsung Galaxy S6] krypto1300:
I also had this problem. Did you restore from backup when setting up your S6? I have a feeling that this is what is messing up some phones. I have 2 S6's and both were configured with identical settings. One had 28 hours standby while the other only had 17 at best.

After Odin back to stock on the problem S6. I just set the phone up as a new device and manually installed the needed apps. Now there are no cell stand by issues and both phone get 28 hours of standby time.
[Verizon Samsung Galaxy S6] steelersmb:
I don't get force closes but my battery life sucks too. I would reset your phone as this was happening with my wife's S6 right out of the box. We reset it and it was fine afterwards.
[Verizon Samsung Galaxy S6] Erasmus354:
No I did not restore, just went through the normal setup process.
[Verizon Samsung Galaxy S6] snk012:
How are you guys getting more than 10 hours of standby time? I think the most I got was 12 hours and that was at 100%. I too set my phone up as a new device and disabled/removed any of the bloat I was able to. I unchecked all of the ticks in the WIFI/Advanced settings so I don't get the cell standby anymore. Just can't figure out how you are getting 20+ hours of standby. [MENTION=2789386]krypto1300[/MENTION] How is your use so far? Is it consistent with what you were getting earlier today?

I'm hesitant about flashing back to stock and setting everything up again as many of you know it is very time consuming. But If that is the answer to improve battery I might as well do it. Just want some more feedback.

This is also kind of off-topic but has anyone had issues with receiving notifications? I am getting Hangouts notifications couple hours after they were sent to me. Same goes for phone calls sometimes. Apparently I got a missed call at 12:45pm today but I got the notification after I rebooted my phone few minutes ago...

Any help is greatly appreciated!
[Verizon Samsung Galaxy S6] krypto1300:
So far my battery is going good today. Haven't had super heavy usage but here are my stats from the same charge I sent pics of earlier.

Odin back to stock and setting up as new phone was the only thing that fixed my battery drainage issue. My wife's S6 never did exhibit the battery drainage issue even though I did a restore from backup on hers when we first got it from Verizon.
[Verizon Samsung Galaxy S6] snk012:
Wow looks good. Prior to ODIN back to stock did you try clearing cache?

Here is mine:
[Verizon Samsung Galaxy S6] krypto1300:
My stats used to look like that.

Yeah, I tried clearing cache, disabling apps, turning off location, wifi scanning, etc, etc. Nothing worked, not even factory reset. I had to Odin back to stock.

Now I have everything turned on and get good battery.
[Verizon Samsung Galaxy S6] snk012:
Guess I know what I will be doing later tonight.

Thanks again~
[Verizon Samsung Galaxy S6] krypto1300:
Hope it works out for you.
[Verizon Samsung Galaxy S6] snk012:
Thanks~ I don't think I will be able to do it tonight but maybe over the weekend. I will post some follow up screen shots after I do~
[Verizon Samsung Galaxy S6] droidiac13:
I'll be giving the Odin trick a try tomorrow. Can't stand this battery life for much longer.

[Verizon Samsung Galaxy S6] Wrw311:
I ODIN'd to stock yesterday and setup as a new device. I didn't restore anything from the backup. Went to bed and it was around 38%, woke up to 18% battery with cell standby at 36%. I do keep the wifi on while sleeping so I guess that's what I'll have to turn off for the time being even though I prefer having that on.
[Verizon Samsung Galaxy S6] :
That's terrible, I only lost about 1% overnight. I use greenify paid but it shouldn't matter that much. Cell standby is still at the top of my list. Charge your phone to 100% and take it to a Verizon store so they can run a battery test on it. Make sure you go there when it's 100% or you will have to wait until it charges up.
[Verizon Samsung Galaxy S6] Gizmoe:
Have you tried unchecking always scanning for wifi networks. I keep my wifi on all the time too and leave that unchecked and have no issues.
[Verizon Samsung Galaxy S6] Wrw311:
Yep that's unchecked, did that as soon as I got my phone back to stock. I'm likely going to swing by the verizon store tomorrow and have them do a check.
[Verizon Samsung Galaxy S6] s197:
VoLTE is also known as advanced calling. You should see a setting where you can turn it off, although I don't see much of an impact to my battery life with it on. I'd also take location off high accuracy and only toggle it to high when you need GPS.
[Verizon Samsung Galaxy S6] Magic815:
So while I agree that doing those things would likely help my battery life, I'm more wondering if what I'm seeing it showing a typical S6 battery. I'm hearing about all these people with 5+ hours SOT and 24+ hour battery life, and while I'm sure they are toggling their location more efficiently, I wonder if them turning it on would cause battery life similar to what I'm seeing or if they'd still get something better. Does that make sense?
[Verizon Samsung Galaxy S6] droidiac13:
You can return it, but I can tell you from returning two of them, it isn't going to get better unless you find some luck. The two before and my current one all have sucked. It doesn't matter what I do. Once in a while I will get 4-5 hours of SOT and then the next day I can't get 3. Same usage, same apps, same everything. Doesn't matter what I do. I am going to keep the phone as I always have a charger somewhere with me, but it does blow!
[Verizon Samsung Galaxy S6] droidiac13:
I didn't take any screen shots prior, but I did just Odin. I'll let you know if it helps.
[Verizon Samsung Galaxy S6] snk012:
Thanks~ hoping you have good results
[Verizon Samsung Galaxy S6] :
Same here. My first S6 was great but I returned it and briefly went back to my Note4. It took me two more returns to get one like my 1st. I paid full retail so I had to pay restocking fees too. I ended up purchasing this one from BestBuy because the Verizon store refused to sell me another. I'll never do any more business with that VZW location.
[Verizon Samsung Galaxy S6] jewillia:
I'm hoping the first update or two we see improves the battery life a bit. I'm happy with what I'm getting after moving from a Galaxy S3, especially considering how much better of a device and OS I have now. It sounds a bit extreme to try device after device hoping that you will find one that has better battery life for some reason, but to each their own.
[Verizon Samsung Galaxy S6] ChaoticHavok:
I am also curious if the Odin to stock sees significant improvements to battery life. The battery life for me is already better than the S4, but looking at some of these pics on the thread makes me jealous of the 20+ hours on one cycle. Keep us posted!
[Verizon Samsung Galaxy S6] :
I agree it's an extreme approach but it worked for me. If I didn't know the difference I wouldn't have gone that route, I would have just stuck my Note4. I'm at two days of use, 3 hours of screen time and just hit 50% on the first charge of this S6. The last one I returned was about half the stats of this one. It has to be manufacturing lots. Most likely I got a "older" one on this last purchase being from BestBuy with a higher sticker price. Either way I'm happy again and Verizon credited my account for the price difference and trouble the store gave me with not selling me another. I would have went to another device but nothing currently compares with the camera and performance of this phone.
[Verizon Samsung Galaxy S6] steelersmb:
I know we are beating a dead horse here but this is so frustrating. Took my phone off the charger before I left to go to lunch, it was at a 100%. It drained 5% in two hours with hardly any usage. As I was taking screen shots, it actually dropped to 94%. I am attaching two screenshots from Gsam. This is driving me crazy how crappy this battery life is.
[Verizon Samsung Galaxy S6] Gizmoe:
As a side note. There are some excellent external batteries out there that are compact, have quick charge 2.0 and a capacity of 10,000 mah or more for around $40. I don't have the batter issues others have but I will be getting one of these anyways.
[Verizon Samsung Galaxy S6] krypto1300:
Yes there are some good ones. I picked up the Anker Astro E3 10000mah. Not sure if it has qc but it charges very quickly.
[Verizon Samsung Galaxy S6] krypto1300:
So 4 days after I Odin'd back to stock my battery is still good. I've setup my phone with my regular apps, but installed them manually from the store. I'm even running a TW theme just for kicks.

Has Odin back to stock and setting up as new worked for anyone else?
[Verizon Samsung Galaxy S6] grumpyj1:
My battery life has been good since i got the s6 i can get up to 6 hrs sot and 20+ hours of standby....the only issue i had was when i would have wifi on my battery would drain a lot faster. Odin back to stock seems to fix that issue. Now i can have wifi on all the time and my battery drains normally, i can still get 5+hours of SOT..
[Verizon Samsung Galaxy S6] krypto1300:
That was my problem as well. Wifi ON would drain the battery. Odin to stock or installing apps manually has somehow fixed that.
[Verizon Samsung Galaxy S6] droidiac13:
I feel like it has helped a little. Today I got almost 23 hours with a charge. SOT was 3 hours and cell standby dropped to 3rd on the list. I wouldn't suggest doing it just yet. Today was lite usage. Give me a couple more days to report.
[Verizon Samsung Galaxy S6] snk012:
Thanks for the feedback. I haven't had issues with battery draining quick as others have mentioned but am still envious of the 20+ standby time. Seems the last few posters have had positive results as well.

Maybe over the weekend you can get more use and see how the it compares prior to flashing back to stock.

I'll wait for more feedback~~ thanks again!
[Verizon Samsung Galaxy S6] grumpyj1:
Yes, i also forgot to mention i set it up as a new device and installed all apps manually.
[Verizon Samsung Galaxy S6] droidiac13:
It has helped. My battery loss over night was only 4%. Cell standby is remaining in the middle of the pack. I'm pretty happy with the results. Thank you for this!

I'm now going to do it again, let all the apps update, root and then remove the apps from the device after doing a Titanium Backup. I'll have to push SU and Busybox through ADB, but it will be interesting to see if the results are even better.
[Verizon Samsung Galaxy S6] krypto1300:
This is a great idea. I may try it as well. Let us know if it helps.
[Verizon Samsung Galaxy S6] droidiac13:
I've definitely seen better battery life since ruining ODIN. You'll see in my screenshots that cell standby is way low.
[Verizon Samsung Galaxy S6] droidiac13:
I'm happy with this now.

[Verizon Samsung Galaxy S6] droidiac13:
Anyone know what these stats represent? Is it good?
[Verizon Samsung Galaxy S6] tluley51:
Why would screen not be an option in my battery usage list? I saw it there yesterday, it is no longer there?

EDIT: Apparently, my screen usage was so low, it fell out of the top 6 most used. It is back. 12 hours off charge, 1 hour and 20 minutes screen on time with 35% battery left. That is pretty terrible.
[Verizon Samsung Galaxy S6] musicfreak190:
So my battery life is not very good. Cell standby is the highest usage.

I guess ODIN to factory using the Factory Restore thread is the way to go after looking at all these messages. I may do it later. I was going to wait for a ROM but I am thinking maybe Verizon fed up the factory image and the Factory Samsung image it better and that it is better off I ODIN then root.

So I picked up an S6 last night on my way home from work, I am coming from an HTC One M8, so far the battery life on the S6 seems OK for my needs, I am at 11h 38m on battery with 57% left estimating 14 hours left and 2:30 min screen on time. I spent a good amount of time setting the phone up to the way I like it, some texts, reading on my Kindle app for an hour, some web surfing. I was a little worried about the battery size, my M8 I would have over 70% each day when I got home from work ( I am on WiFi all day at work) I did have the Verizon tech turn on Advanced calling while I was there based on what I have read here about the battery issues with Cell standby, my Cell standby is third on my list at 7% (is that bad?). Any way thanks all for the great information gathered here, I will update in a few days after I have a few more charge cycles completed.
[Verizon Samsung Galaxy S6] RyanTX:
Compared to my previous moto x 2014, the battery life on the s6 is incredible. I can get 3+ hours of sot and 2 hours of talk time and have battery to spare. Not a chance of that on the moto x.

Great Battery Life

I've had my GS6 for about 3 weeks now and the battery life has been great for me. I average about 4 to 5 hours of SOT. I have been able to push it to over 6 hours a few times, even got close to 7 hours one time.

My setup:

- Nova Launcher

- Google Now enabled

- WiFi off

- Location enabled (set to Power Saving)

- NFC & Bluetooth on (paired to LG G Watch)

- Screen on Auto Bright.

- Smart Stay On

From the Moderator

To all in this forum .......... There has been some Banter about battery charging and how long to leave on the charger ..........

To clear this up.......... The most important thing with most rechargeable batteries to extend battery life, is to use them until they are under 25% before charging. That extends the battery life more than anything. That is not always practical and I rarely do that myself ... mostly because it does not fit my schedule .

That said I have never found a battery to lose efficiency until around 18-22 months of continuous use no matter when you charge it or leave it over night on a charger. I know this to be the facts since I have owned EVERY Samsung Phone since the Galaxy 1 (Vibrant) The only device I do not have presently is the S6 edge .......

To that statement....... Leaving a phone plugged in overnight will not do anything to the Battery. There are more than one safeguard to prevent a battery from over charging. The days of overcharging a battery have long ago left us...... so that is not an issue....

What is an issue is how many times you charge a battery .........So for argument's sake say you use the phone's GPS 14 hours a day most likely you would need to recharge 3 times in that day (you are really draining it out 3 times a day) ..... Basic math people .... in this case, 3 charges a day would reduce the life since ALL Batteries have a predetermined amount of times it will recharge ...... simple

But to reiterate, there is nothing wrong leaving your phone to charge over night.......

Remember ......... Post on topic, Post Kindly, Post Respectfully....... ~~~ oka1
