Are there variants of the stock recovery of the S6 that I should be aware of that can be incompatible with my version of sy?

Ah...

Wonder what else can be the cause..
[Galaxy S6 General] qkevinto:
It doesn't seem like you're having wake lock issues, my Facebook was doing about 900 wake up triggers in less than 24 hours. Do you have LTE/4G on? If you do then pay attention to your signal, if it's constantly low it will cause quite a bit of battery drain. Also try disabling Google Location History of you haven't already.
[Galaxy S6 General] bruiselee:
This is when I'm sleeping and WiFi is connected. Router is in the proximity, so shouldn't be issue of weak signal?
[Galaxy S6 General] jacindc:
See if going into airplane mode at bedtime but then turning Wi-Fi back on fixes it.

The mobile data signal is at the root of all of my battery problems. Sometimes just going into airplane mode for a bit, even with Wi-Fi and Bluetooth and nfc turned back on, will stop the drain. Then it holds for awhile after turning airplane mode off. Eventually have to do it again and again though when the drain inevitably comes back.
[Galaxy S6 General] dandrumheller:
This seems to be my case as well. I haven't been able to do any controlled testing yet, but anecdotally, it seems that once I use airplane mode to toggle the cell radio, the better idle drain sticks until I turn WiFi back on. After that, drain will be heavy on either WiFi or cell radio until I turn WiFi back off an then toggle airplane mode again.

Took a closer look at your screen shots. Did your wake counters reset when you plugged in? If so, we are looking at irrelevant data. You had something keeping you awake roughly 4h20m in that 8+ hour run. It certainly wasn't the partial wakelocks from the apps you are showing. You need to, at least, also look at kernel wakelock times, and show screen on time as well, for more detailed analysis.
[Galaxy S6 General] bruiselee:
The screen shot was taken when I plugged it in, so it should still be relevant
[Galaxy S6 General] dandrumheller:
Are you certain the times didn't reset when you plugged in? For comparison, here is my run so far today. I decided to try turning google now back on, and I believe the majority of the pain you see here is due to that - most of this had location history on as well.
[Galaxy S6 General] DeMi-GoD:
Someone please respond. Does my battery seem okay? And why is android system draining so much battery?

Sent from my Galaxy S6 ~
[Galaxy S6 General] dandrumheller:
I'll trade ya! 9 hours up with almost 3 hours screen on, and over 50% battery left? That's way better than I'm getting.
[Galaxy S6 General] beaverslayer:
Yes, the app. It's very good but is a significant battery drain if not set to go idle when the screen is off.
[Galaxy S6 General] tluley51:
Maybe someone can help me? first day with a Verizon GS6, went 13 hours off charge, 1 hour and 15 minutes screen on time, 30 percent left. I just rooted and wiped cache partition but I know its still going to suck. I have Greenify installed but Im not sure what I should hibernate. I like to keep Location on, at least to "Device Only". Also, I use Google Now a lot too so disabling that isn't exactly an option.

Coming from a Droid Turbo, its hard. One positive thing is that I have like 4 Quick Chargers laying around, but I feel like having to go to one twice a day is going to burn out the battery in no time.
[Galaxy S6 General] Squintz:
Still getting the Cell Standby battery issue after Odin and manually installing apps. Just think it's directly related to service where I am. 4G only gets about 7mb down at work.
[Galaxy S6 General] zaydaboss:
Is this normal? Never seen this on my m8 or other devices.
[Galaxy S6 General] dandrumheller:
Seems higher than what I've seen. How much usage did you have over that time? If that was all idle time then maybe OK, but you have something triggering kernel wakes . How was deep sleep during this period?
[Galaxy S6 General] bruiselee:
Can confirm the battery drain doesn't occur when phone is in airplane mode. 1% for 8 hours of sleep.

Might be some apps judt don't go well with the s6?
[Galaxy S6 General] Japultra:
I see about the same drain when on airplane mode.
[Galaxy S6 General] jacindc:
Did you turn WiFi back on while leaving the device in Airplane mode, or was this with no connectivity at all?

I'm the one who suggested Airplane mode as a fix--when I'm home with good Wifi and not expecting calls, this is what I do, and the battery life is still very good.

I check the default Usage Manager when I'm home and on WiFi and often see that the Mobile Data icon says I am on 3G, even though I am in a big city 4GLTE area. Turning mobile data off and then on again gets it back to 4GLTE. Given that this drain doesn't happen while I'm at work (deep in a building, even), my drain could be mostly related to the cell signal. Never had drain like this on my S4 though, in the same spot.
[Galaxy S6 General] dandrumheller:
I'm starting to wonder if there is something going on with the cell / wifi radios that is going either unreported or misreported in the battery stats apps - maybe because it's running purely Samsung processor and radio. I remember back in the S2 (exynos) days, there was an issue where every time a wake alarm hit the cell radio, it held a wakelock for 6 seconds - so anything that triggered frequent wakes, even if it only needed a second, was absolutely killing deep sleep. I don't think that's the case here, but maybe something similar is going on where we can't currently see it.

I'm also skeptical of the reported percentage of battery drain caused by the screen - I know in screen on mode I am typically showing 15%+ per hour rates of drain on GSam, versus 1-2% in decent idle. While obviously some of this is due to active processors, it seems to me that it is still under-represented in most of the battery stats I have seen.

I also haven't seen any CPU states reported that max out over 1.5GHz - so I assume we are always only seeing the little processors, rather than the bigger ones at this point. Does anyone know of any CPU monitors that actually show all 8 cores?
[Galaxy S6 General] msavic6:
The S6 is a beast on WiFi only use, location on high accuracy and only 4 Google Apps disabled as well as location history disabled.
[Galaxy S6 General] zaydaboss:
The phone was idle pretty much the whole time and not plugged in.
[Galaxy S6 General] dandrumheller:
Do you have partial wakelocks as well? Not sure if the fb in the title of the first wakelock you have there indicates a connection to facebook or not but my first guess is you have some rogue app keeping your phone awake trying to pull data over Wi-Fi (the rx wakelock). You definitely have a lack of deep sleep issue.
[Galaxy S6 General] elbos2k:
ATT just released a software update for S6 and S6 Edge. Hopefully some improvements...
[Galaxy S6 General] zaydaboss:
I'm out and about. I'll provide full stats once it reaches 0. Id have to say I agree I'm having deep sleep issues. Facebook and messenger are disabled
[Galaxy S6 General] dandrumheller:
You don't have deep sleep issues in this screen shot. It's less than 2x screen on. Your Max possible deep sleep here would be around 60%
[Galaxy S6 General] zaydaboss:
Then I wonder why my device is showing why it was awake 3.5 hours while my screen time is not close to that ? I'm losing about 10% a hour no matter what
[Galaxy S6 General] dandrumheller:
You may have something keeping you awake some, but I wouldn't consider total wake time at something less than twice screen on time much of an issue. That's about normal in my experience so far on this device. I'd regularly see awake 3x as long as screen on on my LGOG.

Short run, but here's my current for comparison.

Depending on brightness, I'm seeing from 15 to 20% drain per hour of screen on. If you are averaging say 18% cost per hour of screen on, you are really only burning about 2% per idle hour. That's not fantastic, but if you're on sometimes moderate or poor signal, it's probably normal.
[Galaxy S6 General] scarchelli:
I'm not rooted so I cant see wakelocks unless I do the instructions that are out there (I tried, didn't work). My battery was good, like 7 hours sot, now it's less than 4. Is it because something is waking up the phone? Ive been barely using it because I have a tablet on almost always. the s6 is getting around 3 days standy. Is that why sot is much lower now? Because i haven't been using it as much?
[Galaxy S6 General] dandrumheller:
I'd love to get that kind of battery life.
[Galaxy S6 General] Alarand:
I'm sure it's been discussed already but I can't seem to find the specific post. I had to reflash stock recently and I'm back to ****ty battery life.

Google play services seems to be taking up a gargantuan amount of battery usage. I can't seem to get servicely to work and for some reason play services doesn't show up in greenify.

I've disabled always allow wifi scanning and volte but I can't seem to get it to stop draining battery. What else can I do to reduce its battery usage?
[Galaxy S6 General] ZoZo-:
Charged my phone to 100 %. Unplugged it in bed and played a little bit games on it down to 89 % and then I just put it down next to the bed. When I woke up it had 86 % left so I guess I don't have any unusual drain at all :)

This was with everything syncing, even Samsung services, locations on but not wifi during sleep.

The largest battery drain is the big and bright screen :)
[Galaxy S6 General] daleski75:
This is an interesting outcome I am on my 2nd S6 (first one had touch screen issues) and I have the exact same setup as before (disabled some apps with debloater, no root, stock, location on etc)

1) First S6 would die after about 14 or so hours with 3-4 hours SOT (no matter what I did it would not get past 16 hours max battery life)

2) Second S6 has been going for 1 day 3 hours with 3 hours SOT and it's down to 32% battery

I am using the phone the same way of course, twitter, news, youtube, blinkbox (streaming music)

Quite a difference I reckon and hopefully it will stay that way.
[Galaxy S6 General] Japultra:
Do you listen to music?

---------- Post added at 09:40 AM ---------- Previous post was at 09:37 AM ----------

Yes, I would say that is why.
[Galaxy S6 General] YaviSGS:
The difference on WIFI alone and 4G is very significant for me. With only 4G I get 4 hours of SOT. On WIFI alone sometimes 7, 8 hours.

Here below the result on WIFI and 4G. (8 hours on 4G)
[Galaxy S6 General] Japultra:
I wonder what the issue was with the first phone. Glad you're getting great battery life now.
[Galaxy S6 General] daleski75:
Not sure and this difference is only after the first charge so it should get better as time goes on.
[Galaxy S6 General] ashirokung:
About 6 - 6.30 hour SOT on 4G (location disable).
[Galaxy S6 General] midreestaj:
Quick question: Does fast charging make this phone very hot during charge?

I noticed at the peak rate of fast charge curve;

Ambient temp: 34 degree C

CPU temp: 58 C

Battery temp: 44 C

Isn't that way too hot especially battery ?

BTW I am consistently getting 4.5 hours SOT
[Galaxy S6 General] Shadyfurball:
Not checked the temps but mine does get really hot during fast charge also.
[Galaxy S6 General] Apoxx:
This batterylife is starting to annoy me. Today it's up to about 6% drain pr hour, IDLE. This is getting pathetic.

Sent from my SM-G920F
[Galaxy S6 General] zaydaboss:
On the device? Sometimes. During the screen shots provided no.
[Galaxy S6 General] Solariis:
Huge difference for me since installing the OE2 update. Previously I had to disable VoLTE & any type of security to stop idle drain. After the update, I enabled fingerprint again along with VoLTE and seem to have much better results.
[Galaxy S6 General] elbos2k:
Seems better for sure...
[Galaxy S6 General] scarchelli:
Barely using my phone was what was making the sot so bad. At 3 hours now at 50%. I used my phone a lot today (a lot more, so 6 hours or so sot makes sense). Been on wifi all day basically with brightness on very high for a few hours earlier.
[Galaxy S6 General] jacindc:
Not for me, alas. I am bummed.
[Galaxy S6 General] BluntVanille:
I guys !

1st reply on XDA to speak about my battery :

I noticed that I have already have like 5h SOT with WIFI On, playing Hearthstone, FB, Twitter, SMS. But in 4G, I can have only like 2-3h SOT MAX !

It's like the battery have " 6 hours " life, and will die for sure after 6h of using whatever if you have SOT or 1h SOT

I don't know if is it clear, English isn't my native language like a lot of people here i think !
[Galaxy S6 General] Japultra:
Do you have a weak 4G signal most of the time?
[Galaxy S6 General] ra9b:
So I dont know why my battery life is so terrible. I don't use touchwiz as my launcher, I have my location services on, I am always on data, but I have 4g enabled for group texts (although I may get like 5 a day), yet I still have this battery life. It seems like the system apps transmit a lot of data for some reason... Anyone have any remedies to fix this? I also use autobrightness. I've been reading this thread for a while, and I'm going to disable my 4g connection today since I have weak signal near my house. Some people said that this would decrease my battery drain (although, idk if it will do anything for me, since I have wifi and 4g enabled, but download booster off) unless I'm going out and then report my findings.
[Galaxy S6 General] iamhacked:
My first day. browsing on chrome, watching YouTube, and listening to music.

I disabled a bunch of apps if that makes a difference.
[Galaxy S6 General] dopediculous:
Here's a tip that I do with all my devices. I'll leave a lot of geek speak out, so just do this and y'all should notice a difference, if not a big difference (I can't vouch for those using any "battery saver" apps, as they may be more detrimental than good)

So -> Let your phone (or any android device) completely DIE. Then try turning it on and let it die again. Keep doing this untill you get absolutely NO response from holding the power button. (You'll probably have to do this at least 10 times before the battery is totally drained)

Now plug your device in, keep it off and do NOT break the charging cycle untill about 10-20 min after it's reporting 100%

Unplug the device and turn it on.

Doing this, forces the device to make a new (better/more calibrated) bat stats file.

I do this about once a month and I choose to do this, over wiping the stats file in recovery.

Also... Use WiFi when available, turn it off when not using and the same goes for GPS. This is all I do and I easily get over 15 hrs a day, but everyone's usage is different. So try the charging tip I suggested and see what happens. Good luck =)
[Galaxy S6 General] leandronb:
wft is this graph?
[Galaxy S6 General] iamhacked:
Yeah it's weird how it did that when I woke up and used the phone [emoji2] [emoji1]
[Galaxy S6 General] leandronb:
all you are doing is hurting your battery health.
[Galaxy S6 General] dopediculous:
In what way? Battery's don't have memory in them anymore and I've done this for years. I've never heard anyone say anything negative about this method of making your phone calibrate it's battery stats. Also keeping your battery above 50% is a good idea, but if you do what I said (at most, 1 time a month, you're fine...)
[Galaxy S6 General] leandronb:
when these new batteries achieve a very low level of charge it can be worse for it, and if you force the discharge even more that's in a long term will hurt the battery. i just let my phone discharge once in three or more months, just to calibrate the meter, it will not make battery life of the phone better. anyway these new batteries are so good that even if you discharge it everyday it will still have a 1~3 year life.
[Galaxy S6 General] dopediculous:
So you do the discharge calibration, just not as frequently as I mentioned...?

Again, keeping much detail aside, this is just a simple tip for the battery stats to be reset and to get a more "accurate" reading.

but doing what I mentioned (even if you only do it 1 time) is a good way to be assured that your phones battery stats file is more on point. Agreeing to your point about how good our batteries are, this once a month is still fine and could be of much help if your battery seems to be complete trash, like some people are saying in this thread.
[Galaxy S6 General] omrij:
The infamous battery stats "calibration" disproved long time ago by Google. It's an urban legend, a placebo effect.
[Galaxy S6 General] dopediculous:
If that's true, than are the people with bad battery life just screwed? Lol...
[Galaxy S6 General] Jonathan-H:
Yes of course they disproved it.. oh wait.. like they brainwashed everyone into thinking killing apps doesn't improve performance. Oh wait.. they didnr and it does. I always charge and kill my battery on every phone I own and it improves battery life every single time because when the phone says it's dead, or 1 percent, it's not. I get 6.5 hours screen on time now from 4 when I first had the phone with brightness at 75 to 100 percent and Gmail and WhatsApp going.
[Galaxy S6 General] -Mr. X-:
Yep, its well documented that lithium based batteries can be damaged by "deep discharge" (discharging below a certain voltage).
[Galaxy S6 General] shadow82x:
So I've been getting around ~3-4 SOT every charge and was looking for some advise. I use, what many would consider, battery draining apps. (Snapchat, tinder, instagram, facebook, messenger, etc.) I was wondering what I could do to maximize this SOT if anything? What default apps/services are recommended to be disabled? I currently have all carrier bloatware removed, svoice, samsung push services, etc. Is there anything else that should be disabled?

My locations services are set to power saving. I disabled wifi scanning. And I have Advanced Calling enabled.
[Galaxy S6 General] ysrini:
Over-discharge affects each battery system differently and can cause permanent damage if allowed to dwell in that state.

Li-ion should not be discharged below the manufacturer specified level and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell and lower, the battery’s protection circuit may put the battery into a sleep mode. This renders the pack unserviceable and a recharge with many chargers is not possible.

I'm getting around 4 hours SOT (mostly wifi , some apps disabled) with 20% still remaining , I always charge when my phone reaches 20% .
[Galaxy S6 General] bruiselee:
battery drain was bad this morning.. 40% over the span of 8hrs of sleep.

wifi on and cell on. non airplane mode.
[Galaxy S6 General] dandrumheller:
Did it automatically update or install a ton of apps over that time span? If not, I'd try clearing data and cache on the play store - it appears to be hung.
[Galaxy S6 General] bruiselee:
I unchecked the auto update of apps since day one.. So that shouldn't be the issue, but I will try wiping data and cache like u advised
[Galaxy S6 General] ChristianBale:
Android System is what is killing me right now. Any ideas anyone?
[Galaxy S6 General] wevocy:
I get about 30% discharge over the course of a night's sleep. It is a disgrace IMO. On the other hand my nexus 4 maybe 5% and i was using it for 2 years non stop. Tbh am worried if there will be a perm battery damage until my device gets the OTA fix. :confused:
[Galaxy S6 General] Shadyfurball:
How do you disable the volte thingy? I've checked in the advance settings in the phone app and don't see the option. I guess it's hidden and needs a code to reveal the option? But is volte therfore off if the option for it is hidden by default? UK here and phone bought from Samsung online.
[Galaxy S6 General] ra9b:
For me, I have a setting called advanced calling. But it may not be there for you.
[Galaxy S6 General] daddioj:
I got about 7 hrs OST with about 20% left. this was all wifi though. I have yet to try LTE. anyone have weaker signal? then previous phones?
[Galaxy S6 General] DZH1:
I did my best to give the Gs6 another shot coming from Xperia Z3 but so far

it's just not working... and I really want it to work based on the camera alone.

Brilliant camera and amazing screen.

I left the house with 100%, 3G only , all settings switched to run 3G only etc...

screen on 75% brightness, took about 10 photos, no video and

after 15 minutes with maybe 8 minutes screen on time I was at 87%

No facebook installed, maps not running in BG.

Have to go back to Z3 until this issue is addressed, but really hoping because

otherwise I love the phone.
[Galaxy S6 General] bruiselee:
another night of sleep, another night worth of battery woes data..

this time round i offed my wifi and just left lte on.

battery drain was just as bad..

i tried betterbatterystats app as well.

this are the stats ...
[Galaxy S6 General] rajeshjsl:
Taken at two different instances before charging . (Only using wifi , sim not activated currently :rolleyes: )

Getting 4 hrs 37 mins (youtube,chrome,poweramp , etc) and 20% still remaining on flight mode . (Adaptive mode at 33% brightness for first 2.5 hrs , Basic mode 33 % brightness for the rest , liking basic mode now) .

Really getting frustrated. I'm not sure why my battery life sucks so much with this phone. Light to moderate use - some texting, maybe 2 Google searches and a quick article on Wikipedia. No videos, voice calls, etc. WiFi on, VoLTE and WiFi calling disabled. I have 8 hours on battery and 2 hours SOT. Down to 30% battery already. Screen (11%) is on top of the battery list and Android OS (3%) is second - with 2 hours 59 minutes keep awake time.

[Galaxy S6 General] dandrumheller:
Dude, that's just messed up. Phone app had 10 wakes per minute over 8 hours... Something ain't right. Did that run have any deep sleep at all?

I'd guess that some app is causing that. Maybe facebook based on its reported drain in the regular battery app? Just a wild guess. If I were in your position, I'd try freezing facebook and repeat the same run. See if those phone alarms quit.
[Galaxy S6 General] CConn882:
So after a couple weeks of using my S6 (I got it around April 13th or so), I was getting seriously worried about the battery life. A lot of battery drain when idle, wifi taking up a big percentage of battery life, just barely 3 hours of SOT per charge, etc. I was getting pretty pissed, especially considering I'm pretty neurotic when it comes to phones. I was coming from a OnePlus One, so I was used to getting 6+ hours of SOT.

Since then however, the battery's improved a decent amount. It's certainly not OnePlus One/Note 4-level battery life, but I really didn't expect it to be. Here's my screenshots. I'm on T-Mobile. I have voLTE and a few Samsung apps disabled, but mostly everything else is turned on. Bluetooth, Facebook app, no battery saver mode, etc.

My standby time could still be better - I swear if the standby drained less juice, you really could get 6+ SOT on this phone - but other than that I'm very pleased with it.
