I'll throw in my experience re: cell standby / battery issues with my S6. I got the S6 on June 26th and noticed an issue with the battery right away. I figured this had to do with me not putting the device down and the fact that I came from the Turbo which had monster battery life. As days went on I noticed that it wasn't really changing and that Cell Standby was at the top of battery usage by a lot. I've never seen this with any Android phone I'd owned previously. Almost always screen usage has been at the top.

Long story short, on the 30th I was on vacation out of state and my battery life went to amazing and cell standby was nowhere to be seen on the chart. Granted, I was on WiFi half the time I normally would be at home but the increase in battery life was ridiculous - something like over a day left when I was already 8 hours off of a charge (and I was using the phone for navigation while driving, music, etc.).

So, maybe the cell standby issue has something to do with strength of signal in your area? I've noticed the mobile signal of the S6 isn't as good as my Turbo was in the same locations at home and work. I honestly have no idea but I thought I'd share my experience for the sake of having more information.
[Verizon Samsung Galaxy S6] skim234:
cell reception definitely plays a role in battery life.
[Verizon Samsung Galaxy S6] Chadwick17:
Oh, I know that for sure. The weird thing to me is the complete absence of cell standby in battery usage when I was in a different state. Things like Instagram and IF were showing in the top six and I wasn't even using them at all.
[Verizon Samsung Galaxy S6] skim234:
they were running in the background. if you go to settings, data, click on any app listed and there's a way to turn off background data.
[Verizon Samsung Galaxy S6] Chadwick17:
Right - I'm just trying to wrap my head around why there is such a dramatic difference in the battery usage of cell standby. My wife has an S5 (on Lollipop) and in the same locations cell standby doesn't show up at all in her battery stats.
[Verizon Samsung Galaxy S6] Gblake13:
Check out the battery life of my junk s6 had it two weeks. Is this normal?
[Verizon Samsung Galaxy S6] supersmash19:
That's even worse than mu battery and I messed mine up so I'm pretty sure there's an issue with yours.

I was really stupid and did something real dumb. I used to always hear putting batteries in the freezer helps them.... THIS IS A BIG LIE!!! I usually do research before trying things like this but I didn't this time and I hate myself for it. I used to get decent battery life and it'd at least last me most of the day. Now it dies after about 6 hours in all with like 3 hours sot.

I was putting it in the freezer for like 5 minutes once every couple days and then I started noticing the battery was getting worse and so I stopped and looked it up and saw that lithium ion batteries don't do very well in extreme hot or cold. Considering I'm in egypt for the summer and was also at Saudi Arabia it had some extreme heat and then I go and put it in the freezer as well and that must've just finished it off. I'm really happy we get one free battery replacement because as soon as I'm back in the U.S I'm getting mine changed out.
[Verizon Samsung Galaxy S6] Chadwick17:
Interesting development: I was reading some other forums and somehow stumbled across a Google Code page that listed out mobile data / cell standby as an issue for Android. There were literally thousands of people commenting that they have a similar issue.

One person noted that the email app was bringing their battery down due to it constantly syncing across the mobile connection even though they were on WiFi. They turned syncing to manual for the stock email app and their battery life dramatically increased.

I tried the same thing since I'm desperate for anything to help with the cell standby issue. It seems to have worked on some level. I'm now seeing roughly 20-21 hours remaining after 7 hours into a charge. Cell standby is no longer at the top of battery usage and isn't even half of what is now at the top. Hopefully these results hold up.

So I called verizon (again) and I got the do a master reset and if (when) that doesn't work we'll send you a like new device to replace the like new device and screw you customer. I already told them I don't want that junk. Well we can't send you a new one almost a week over the refurnished period. after you signed an agreement to pay us payments on a brand new phone to pay brand new,price and get stuck wit b some old junk we're obligated to call like new. I hate verizon. And this is my first and last samsung too.
[Verizon Samsung Galaxy S6] supersmash19:
Why don't you just get the battery replacement free from samsung? No need to get the whole phone replaced. It has a one day return window so you may be without a phone for about 2 to 3 days max and if you have a backup you should be fine.

I just used GSAM battery monitor and it may be that it's not my fault the battery sucks. If it actually let's me post the pic you'll see Google services taking up way too much battery. It's at 76.9% and the next thing on the list is android system at 4.4%. My screen on time is only 5 minutes and the battery has already dropped to 65% over 5 hours of standby.

I'm gonna factory reset as soon as I have a chance as this seems crazy.
[Verizon Samsung Galaxy S6] coffeehandle:
Does anyone have this large mediaserver percentage as well? Using GSM shows this, but the native battery monitor shows a high android system usage. Any insight would be great!
[Verizon Samsung Galaxy S6] LT.Dan:
Wow, had this phone about a week and a half and this battery life SUCKS! 5 hours off the charger, 30min of screen on time and it's down to 60% left! I'm debating returning this junk and getting a droid but I do love this phone.

Cell standby is at the top of battery usage at 12% followed by android OS at 4%.

Any pointers? I tried clearing cache in recovery and enabling advanced calling without any changes.
[Verizon Samsung Galaxy S6] supersmash19:
I had the same problem as you and I'm still not getting that great of battery life but rooting and installing clean rom lite helped. Also I set my WiFi to turn off when the phone is sleeping. That seemed to help the most as I think a WiFi bug is causing the drain. If I turn WiFi off over night I only lose like 3 to 4 percent. If I don't I lose anywhere from 15 percent to 30 percent. It's so random and it's really annoying. I'm gonna get the free battery replacement and if it doesn't help as soon as the next nexus comes out as long as it's camera is as good and if battery is better I'm selling this and buying it. That Huawei one is looking really good right now and the other rumored one from LG will probably be good as well.
[Verizon Samsung Galaxy S6] co.ag.2005:
What's the free battery replacement? Is Samsung replacing batteries on these phones if there are issues? I charge like 3 times a day. Love the phone! But this battery life is dumb.
[Verizon Samsung Galaxy S6] supersmash19:
They test it and see if it's less than 80% of original capacity and then they'll change it for free once. If you make a big deal even if it's not less than 80% they'll probably change it as they promised one free replacement to everyone. After that it's I think around 35 to 40 dollars for a other replacement. Go to a Samsung store near you and you can have it done and have your phone back In the same moment or else you'll have to ship it and it has a one day turn around so you might be without your phone for around 3 days. Best thing is to see if there's a Samsung mobile store nearby or maybe your carrier will change it. I got mine from best buy so I'm gonna see if they'll change it and if not I'm gonna look for a close samsung store.
[Verizon Samsung Galaxy S6] co.ag.2005:
ok, thanks for the reply! I assume at a Samsung store they'll test the battery first. I'd like to have that done anyway just to see. I purchased my phone on 7/3 from my local Verizon store, so I doubt my capacity has dropped at all. But I'd like to see if there's maybe an issue with mine or if it's par for the course for this phone...
[Verizon Samsung Galaxy S6] deranger:
Battery life on this phone is more than acceptable IMO. I idle at about 2% per hour; I have no idea what is causing everyone's problems. Charging three times a day, seriously? You need to install better battery stats and see what's going on. I noticed that with IGMP snooping enabled on my router it would drain the battery quicker than usual but nowhere near the terrible battery life I see being reported here. It's not anything with the phone, its with some software you guys are running. After buying the phone I cleared cache both through recovery menu and the storage menu. These are separate caches, I am not sure which one is "recommended" to clear so I just did them both. I am running Google Now with the voice recognition available everywhere, something that would normally destroy my S4 battery life, and I am getting better battery life with it enabled on the S6. Really, check your battery usage more in depth by rooting and installing better battery stats. This is an excellent phone and the battery life is on par with other flagships.
[Verizon Samsung Galaxy S6] LT.Dan:
Did you read the thread? A lot of people are having this issue and it seems to be due to cell standby. There wouldn't be a thread if there wasn't an issue.
[Verizon Samsung Galaxy S6] :
You should install Greenify Paid if you think 2% per hour loss at idle is acceptable. Mine is stock with no root running the default launcher and I loose about 1% overnight. I have to agree that the phone is more than acceptable for battery life.

Cell standby is at the top of my list and I still get great battery life.
[Verizon Samsung Galaxy S6] LT.Dan:
This is with <30min screen on time..... and this isn't the worst I've seen. Yet some days I get through 8 hours standby with about 60 minutes of screen on and have about 70% remaining.... (at the same locations)
[Verizon Samsung Galaxy S6] :
It looks like it comes down to user preferences. I never leave NFC, Bluetooth or any radios on when I am not using them. My usage list looks pretty much the same, just my radios and data are off. I also have apps disabled with the debloater tool and can share the disable list if you want.

EDIT: Here are my battery stats so far with a little over one hour of screen time along with my debloat list for those who want to try it.

i've recently been getting really good SOT (6.5-7.5 hrs a day). i'm using the Clean Rom Lite 1.1 rom for about 2 weeks. the SOT has improved over time since then. when i first installed the rom, i was getting about 4 hours a day of SOT on it. i guess the rom needs some time to mesh well with the other parts of the phone. my network connection is average at best, too. i usually am between 2-3 bars of signal.
[Verizon Samsung Galaxy S6] supersmash19:
I was getting terrible battery life but after about 2 weeks on clean rom it's finally settled in and I recently got 5 hours and 50 minutes screen on time and 17 hours standby with 10 percent left before putting it on the charger (this is the only time I screen shotted it but other days have been similar though slightly lower sot)

Also I now only turn on mobile data when using it instead of keeping it on constantly and that has helped a ton. Data and wifi really suck this phones battery dry more than other phones I've had so I hope that can be fixed in a software update, if not then I'll have to love with doing what I'm doing now which is fine though I'd rather not have to.
[Verizon Samsung Galaxy S6] LT.Dan:
Well I think it boils down to Wifi..... whenever I have Wifi off I get fantastic battery life! I get about 4+ hours of SOT with Wifi off. I guess it's a good thing that I have 10gb of data to use until they fix this.
[Verizon Samsung Galaxy S6] krelvinaz:
I have WiFi on all of the time when at home and work. Only turn it off when I'm not at those two places or a few others with non public WiFi. I never use public WiFi. No problems with battery.
[Verizon Samsung Galaxy S6] Chadwick17:
I definitely see a difference on WiFi. Probably get 6-7 more hours when not on a WiFi connection.

Sent from my Samsung Galaxy S6
[Verizon Samsung Galaxy S6] supersmash19:
It's definitely wifi.

Without WiFi I get almost 6 hours sot and 18 hours standby which is more than amazing for me.

On wifi I get this amount. Granted there's still 40 percent left after a night and a little more use in the morning it'll be down to zero with only about 13 hours standby and 3.5 to 4 hours sot which isn't terrible but wifi is draining more than it should especially in standby.
[Verizon Samsung Galaxy S6] PhallusOfGod:
Everyone should have a charging case handy.
[Verizon Samsung Galaxy S6] Chadwick17:
Noticed something else the other day. I was getting decent battery and I had WiFi on all day. Even went for a run in the morning which uses very accurate GPS location. What wasn't on, however, was Bluetooth. I got something like 27-28 hours of battery with close to 5 hours of SOT AND cell standby wasn't at the top of the list for battery consumption - Android System was. That's what I would expect from a phone. Turned Bluetooth back on today and sure enough, cell standby is back at the top and I'm looking at roughly 19 hours of battery time for the day and have only had about 1.5 hours of SOT.

Nothing changed between the two days as far as usage goes - just that Bluetooth was on one day and not the next. Odd.
[Verizon Samsung Galaxy S6] Kalnel:
Since I bought mine in early May, I've been getting great battery life (26+ hours with light use) with wi-fi and BT on. Then, about two days ago, "Email Sync" has been draining my battery like mad. I haven't been able to get more than six hours on standby.
[Verizon Samsung Galaxy S6] Chadwick17:
I had that sync issue as well with the stock email app. I set it to manual and since then it has been fine. Oddly, it will still sync on its own twice a day.

I had BT and WiFi on when I traveled out of state last month and I was getting battery life in the 30 hour range so maybe it has something to do with the cell signal in my city.

I can't imagine turning off WiFi or BT would net you an additional 8 hours of battery, would it?

[Verizon Samsung Galaxy S6] Kalnel:
The weird thing is, I've been using the stock email app with no problem for months. Something must have caused this new battery drain.
[Verizon Samsung Galaxy S6] Crucia1:
Hey guys, check out this thread I made, I found an article on reddit and it has helped me alot in regards to cell standby. I remained at 100% after removing from the charger for 17min 16sec before it dropped to 99%... I am not curious how well it could do on power saving mode.

I flashed the Revolution Rom and Cell Standby no longer shows up at all even with wifi on all day. Battery life is great now.

[Verizon Samsung Galaxy S6] Kalnel:
I don't want to root or flash until Samsung Pay comes out.
[Verizon Samsung Galaxy S6] CJ74753:
I only wish I could root so I could change my rom to get better battery life. Mine came installed with OF1 and I hate not having root.
[Verizon Samsung Galaxy S6] LT.Dan:
I've had it with this crap now, here I sit half way through a work day after having barely used my phone and it sits at 41% battery. I'm moving on to something else!

Edit/Update: I contacted Verizon and they are sending me a replacement. We will see how that goes, especially since my home button is loose and "clicky" as well.
[Verizon Samsung Galaxy S6] vondiesel:
Cell standby and android system are big users, at least according to my battery stats. But even with that drain, I still can get 5-6 hours with moderate use (email, web, a few videos, music, pandora, facebook, and occasional GPS). If I keep the screen brightness down, I can get near 7. I'm on CleanROM Lite 1.1 and I use Cloud Magic for my work email, instead of the stock app.

I'm curious to try the "cell standby fix" with advanced calling, but I haven't bothered to turn it on/off yet.
[Verizon Samsung Galaxy S6] iowabowtech:
Same exact situation here. I finally got tired of it and Greenified the stock email app. Appears to me it still retrieves messages when the screen is on which is plenty often for me on any given day.

Amazon App Suite and the Amazon shopping app have both become battery users lately as well. Added them to the Greenify list just now also.

My battery life trends have been steadily declining though I still haven't had to charge this phone mid day outside of an extremely heavy day's use which is an anomaly to me. So not complaining, just passing along what I'm seeing. Since I'm still on the same s/w version since purchasing the phone, it appears to me, the increased drain is due to apps updating and behaving differently in the same environment.
[Verizon Samsung Galaxy S6] :
Got a link to that revolution rom? I can't seem to find it.

While not outstanding, hasn't been too bad today. Still sitting at 33% as I type. I don't seem to have the cell standby issue?
[Verizon Samsung Galaxy S6] jntdroid:
Have you been off of wifi and on cell data most of the day? Yours looks similar to mine with Services and OS burning up a lot... :confused:
[Verizon Samsung Galaxy S6] broons:
4g majority of the day. From 7am until about 8pm. WiFi from 8 onward.

[Verizon Samsung Galaxy S6] jntdroid:
That backs up another claim that Cell Standby is directly related to wifi - my usage reflects this as well.
[Verizon Samsung Galaxy S6] broons:
Hmmm could be. Since being on WiFi the last 4 hours cell standby is now nearly at the top of my battery hog list.
[Verizon Samsung Galaxy S6] iowabowtech:
Crazy that wifi may drain battery faster. Isn't it supposed to be the other way around? :D

Have unlimited data. I'm switching off wifi and wifi scanning following tonight's charge. Will report after a full day tomorrow. I've been on wifi all along and have been hammered by the cell standby bug. It's in excess of triple the battery user of anything else each day on my device including AndroidOS/Android System/Screen.
[Verizon Samsung Galaxy S6] chris mackenzy:
For me, I can't say it bad as on average it is providing me 1 day backup time and I think for these kind of gadgets with so many services running all the time this time is fine. For all those who are suffering from the battery issue I would suggest them to optimize their use and kill the unwanted services manually or via any 3rd party app. I hope this will help.
[Verizon Samsung Galaxy S6] jntdroid:
That was me today and Cell Standby did drop significantly, but it was simply replaced by Google Services at the top for whatever reason... :confused:
[Verizon Samsung Galaxy S6] iowabowtech:
Dammit ok good to know. I'll see if mine follows suit. Just for grins I tried switching from global to cdma/lte today...that was a bust. No difference there. I'm trying every combo I can think of even if they seem implausible. It may take an update to fix, and that's fine. But I'm not going to sit on my hands and wait. College try #3 coming tomorrow. Other ideas welcome.

edit: I feel like we could be overlooking some other ideas. I'm probably changing too many variables now but I'm running out of time with this phone so if this works I'll move backwards instead...at accounts, I'm disabling Samsung account. Entirely removed vzw Cloud which was active somehow - don't remember starting that up. Disabled all the but essentials for sync on my 2 Google accounts. Google fit data was enabled without my knowing for one, that could be a contributor. Play movies/tv, anything to do with Google+ all disabled along with Drive. I don't use any of those things.

Tomorrow is a new day. We shall see.

I was wondering if the global setting would make a difference.

I'm doing fine with battery. I ended with 3 hours and 40 min of screen time
[Verizon Samsung Galaxy S6] trikotret:
It appears you unplugged it at midnight. Did you use it for 23 hours straight or there was some standby time while you slept :)
[Verizon Samsung Galaxy S6] jntdroid:
It looks like he didn't touch the device until around 1-2 pm, which, factoring in the idle time, gives him maybe 11-12 hours of actual usage with 3:40 SOT?
[Verizon Samsung Galaxy S6] trikotret:
People need to know it's really not competition of who gets battery better than others. We need to have normal phone usage during our daily lives to compare batteries. Keeping it on idle while sleeping doesn't help us. Lol
[Verizon Samsung Galaxy S6] jntdroid:
Exactly. Nobody is going to have the same usage patterns. I just want to figure this battery out so it can be functional on a daily basis. I'm not looking for Droid Turbo or Note 4 battery life, but it should be able to do more than it is right now.
[Verizon Samsung Galaxy S6] hopesrequiem:
Sheesh guys. You asked for usage times. I provided them. I don't charge my phone over night so obviously there is idle time. When do you people charge?

[Verizon Samsung Galaxy S6] Gytole:
I notice setting my screen to basic squeezes more battery life out. I average 6.5 hours SOT and it is not uncommon for me to go over 7 hours.

The longest I went before she died was 7 hours and 36 minutes. But before I could grab a screenshot she puked.

I also dont use a lot of apps and I use specific root apps. Im thinking about making a thread with what ibe done to achieve my battery life.

My buddy is blown away everytime he is with me because his S6 gets 4-5 hours and mine is still going even after he pulls it off the charger again. Haha

Help: My Samsung phone battery run out within one day!

Erm, I don't know why the memory is about 80% occupied even I uninstalled a lot of apps from it. And, the battery life didn't last long. Just a simple dialing for half an hour, texting, Waze and Facebook. Then, the battery dropped below critical level: 12%. Anyway to save it?
[Verizon Samsung Galaxy S6] ra9b:
The memory usage comes from system apps and processes that are running. Things like settings, wifi processes, Bluetooth processes, etc. Not much you can do other than flash a debloated rom.

All the ram usage isn't bad though. I'm fact, a lot of free ram could be bad for your phone.
[Verizon Samsung Galaxy S6] hitman4274:
ram on our phones and ram in say a desktop are indeed a bit different...and with a powerhouse of a phone like the S6 I wouldn't be worried about the phone taking up 80% of the ram
