I've searched to understand what's keeping my phone awake and killing my battery and I can't figure it out.
Some background on me:
I'm very familiar with using SS, HoB, flashing ROM's, wiping. FDR, etc, for the Bionic.
Have Better Battery Stats to try to watch what's eating battery.
was on .905, did FDR, used HoB to get to .246 leak after it was confirmed same as the OTA....
Now on .246, rooted with HoB.
Not using TiBu to restore any apps or data.
Have installed better battery stats to understand what's keeping my phone awake.
Whether on the stock rom, stock rom de-bloated, or Eclipse...
Unless I use smart actions to turn off cellular data + background sync (while on a stock rom) there's one common thing keeping my phone awake (kernel wakelock):
bpwake
If I turn off cellular data + background sync then I don't get gtalk notifications/messages, and I've even had some texts not come through when I had those 2 features off (which I thought was strange, not even mms, just regular text messages) and the text never came through even after they turned back on.
I understand that if you don't use your phone a lot, AndroidOS is going to take up a bit of the power drain. No worries there.
But the fact that I'm on an extended battery and I'm halfway through that in less than 5hrs with MINIMAL phone usage- that just doesn't seem right... I could understand that with the standard battery..
My concern is that the "keep awake" time seems rather high in relation to screen time...
I can't find anything on bpwake other than a post about the droid razr, and there wasn't ever a response to that post.
Anyway, I've attached some screenshots of my kernel wakelocks from BBS, as well as battery readouts from the settings and screen on times plus the AndroidOS keep awake time.
I know it doesn't look like the phone is waking up very often, and I've seen much worse in the past, but it seems as though there's still something that's keeping it awake.
I'll try another FDR, and reload .246 through HoB and see if it helps any but I figured I'd reach out here for any help.
Thanks

Your first problem is the 30 mins you went without data. The phone when it does not have a signal will continuously attempt to regain the signal. That is what is triggering the wake ups. If your going to be in dead zones put it in airplane mode.

Interesting, is that true even if you turn mobile data off? It's not clear if the OP turned it off or was just in a dead zone.
I ask because I'm chasing the exact same problem on Stock-Rooted .246, on a stock battery. I don't charge at night, rather I charge in my office during the day. So my phone sits off the charger during the night so I get a good idea of battery drain in standby. Since loading .246 OTA, with data/sync/4g on sitting overnight I was seeing a 12% drop in a 7 hour overnight period, with GSam Battery Monitor showing most of the drain going to Kernel activity. Not bad I guess, but seems way high to me. In comparison my previous phone (Dinc2) would only drop about 4% overnight with data/sync on.
So in an attempt to improve it and get her to sleep, I turned off Mobile Data and Background sync, leaving just the cell radio on. It's my only phone so I'd like to at least be able to receive an emergency phone call in the middle of the night, god forbid. In the same 7 hour period, with mobile data/sync off, I saw an 18% drop, GSam saying 49% of that went to Kernel activity. So, no mobile data/sync, yet the Kernal is still that active, with more drain??? What in the world is the kernel doing, it should be in a deep sleep. Any insight?
Not sure what the no service was about, as I've got service where the phone is parked most of the day (at my desk) but I notice it is still saying I have no data connection or no signal as of now (2h23m off charger, 35min w/ no data connection, 28m w/ no or unknown signal).
Anyway, I've gotten the kernel wakelock (bpwake) down significantly by turning 4g off and leaving it with 3g only.
Battery life is rather exceptional now with only putting the phone in 4g if it's necessary...
Eventually I'll try Eclipse again and see how that works with 4g off and using 3g exclusively (when I'm not on wifi, of course).

Just to eliminate this variable, I should also state I show radio signal was good, 4-5 bars all night long.

You say you're on .246, forgive the Noob question, but how are you switching it to 3g? I appear to no longer have that option in .246 OTA.

I'll have to second the question above - how are you able to turn 4G off Dan? I'm on stock, non rooted .246 (planning on root is what brought me to this part of the forum) and the only trick I know to manipulate the network type is *#*#4636#*#* - last night I switched to LTE only and all of maybe 10% overnight. Of course, I can't make any calls (no calls over lte iirc?)
thanks for looking into this! I'm going to have to monitor battery stats a lot more with this phone...
Digging through more GSam stats, I'm seeing 300+ wakelocks from the mediaserver. I'm sure this is probably not helping matters. Anyone know what causes this and how to stop it? I'm certainly not listening to music or viewing pictures in my sleep.
I'm using the lte switch app for the thunderbolt to turn off 4g. Available from the play store.

I started using BBS as well, my BP Wake is in check, though I'd still like to know what that is.
However, A big draw I'm seeing now is very similar to the OP's screen shots that he didn't mention. Anyone know what OMAP_USBHS_Wakelock is? I googled it, but Only references I see are just a few others just asking what it is with no resolution.
This should help.
First, I found this: http://forum.xda-developers.com/showthread.php?t=1886166
Which mentions wakelocks and battery drain. Same as yours and the OPs.
Next, I decided to search *just* wakelock in Google: https://www.google.com/search?q=wak...zilla:en-US:unofficial&client=firefox-nightly
Which led me to the following two links here at XDA:
http://developer.android.com/reference/android/os/PowerManager.WakeLock.html
An explanation about PowerManager.wakelock methods used in Android, and
http://forum.xda-developers.com/showthread.php?t=1827676
"A Comprehensive (but not by any means definitive) Guide to Wakelocks"
That should answer most questions.
)This next part is me surmising - I may be way off base, but this is what I gleaned from reading through all of these things quickly)
In our case, it seems like the kernel is now built in with some sort of USBHS driver for our OMAP chipset, which means that it now allows programs (apps) to call that PowerManager.wakelock method and keep the phone (or specific parts, such as the chipset, CPU, etc. - which means, of course, more battery drain.
The problem is the weak mobile network signal and the power it takes to maintain it. On the other hand, the weak mobile network signal is apparently a problem in ICS only and GB does not have this problem to the same extent.
In some ROMs the battery drainer shows up as "Android OS" but in others it shows up as "Phone radio" or whatever it is that signifies that.
I do have the GSM/WCDMA hack enabled though and it seems to only happen with that.
So did anyone find a solution? I'm in the same boat. My extended battery is not lasting in ICS like it did in GB. I cannot even go 8 hrs with minimal use off charger.
Zetachi - the only thing that I've been able to do in order to increase battery life is to turn off 4G unless I need it. With using strictly 3G (and wifi when I'm at home) I'm getting much better battery life.

LOL kind of defeats the purpose of having a 4G phone and service
Eh, you still have the 4G without the drain. While not the most optimal situation, at least its easily remedied with just a few clicks.
Certainly an inconvenience, but those of us with the Droid Bionic have got to be used to that feeling by now!
I use WiFi at home and 4G everywhere else. I get great battery life.
Something I learned, though, is that the Gmail app will sync with the servers every 5 minutes if you create and save (not send) a draft. That will eat up a lot of battery over the course of a night (or day).
Something to think about.

Be careful with this method. I know you posted this a while back but it may be helpful for others to know that the phone can lose data all-together using this method. It has happened to myself and other users as well.

Try not doing that.
Looks like you have no 4G where you are... make sure you are set to CDMA only in the network settings.
My battery seems to suck a little bit, too. On the drive in to work this morning, a 1 hour commute, my bionic sat on the seat next to me without being used. It still managed to chomp through 20% of the battery. So, basically at that rate, I'll get 5 hours of standby. Wonder if something is wrong?
Bluetooth (which seems to be a battery hog) was off, wifi was off... not sure what to do other than swap the battery with a replacement.
install system panel, turn on monitoring for everything, use that to determine how much cpu useage apps are using.
if you have an app(s) that are using near 100% cpu useage 24x7 that would happen
I have had the phone since 9am yesterday and have not been impressed with the battery so far. Today was the first full charge and I am at 60% after 2.5hrs. Most of my power consumption has been "Cell Standby" and not the screen which I would normally see.

Thanks! Will give it a try and report back. I hope I can get this resolved.
UPDATE: Installed System Panel and ran it for a couple days. Nothing seemed out of the ordinary. I let the phone discharge completely and then charged it completely before turning it back on. I got about 26 hours of moderate use before it needed to be charged again. Slightly heavier use got me to about 15 hours. There doesn't appear to be anything wrong, and the battery is light-years better than that of my old Eris. So I'm happy!
I'm actually getting pretty good battery life.. I use wifi when im home and at the office. With moderate to heavy use I didn't need to charge my phone until at least 18 hours. I know most say its not necessary, but I have a habit of fully charging my phone prior to first use and allowing it to drain completely before recharging.. perhaps that helped..
My battery has been doing great so far. Been using it a lot today and I'm at 45 percent after 8 hours of use. In me experience, it takes a few full charges before a battery gets fully calibrated. I've read that elsewhere as well. I've been very satisfied so far with battery life. I keep it on wifi at home and work so that probably helps alot.
I would say do a few discharge/full charge cycles on the phone first. Give it a few days to calibrate properly.
Also custom ROM's should help to remove undoubtable bloat that this phone comes with.

No 4G here either, didn't think to change that. Thanks! One additional question about the battery. I have a battery widget that displays the % remaining. I noticed that it drops in 10% increments instead of 1% like it used to on my Eris. I also checked About Phone > Status > Battery level and it seemed to decrease in 10% increments there as well. Is this normal with the Bionic? Or is something wrong with mine?
Has anyone else noticed this?
mine seems to be dropping by 10% as well, but my usage has been fairly good. Much better yesterday than today. Should know better if a day or two.
Task killers are bad since Froyo (2.2). Android actively manages applications and shuts them down when space is needed. Your task killed just winds up arm-wrestling with the OS, making both work overtime and not accomplishing a thing. Let the OS do what it's designed to do.
For those of you just starting with 4G, if you live in a non-4G area or are on the border where 4G and 3G constantly swap out, this will play hell on your battery, so turn 4G off unless you're in a place to take advantage of it.
Pentile screens are power sippers, so don't be surprised if your screen % is lower than normal.
I may be wrong, but I don't believe dual-core processors consume too much more power than single cores under normal circumstances.
Turn off bluetooth, satellite and wifi when not in use, and especially when unavailable. Leaving wifi up when you're away from home can chew up a lot of power as the phone is constantly seeking a signal.
Putting the screen on auto brightness may save some power. Also setting the screen time-out to a reasonable time will help.
Make sure you don't have a dozen accounts like Facebook, Gmail, Yahoo and Twitter checking for updates constantly.
You don't have to train lithium ion batteries like we used to with nickle-cadium back in the day, but your battery has some simple logic in it that takes care of housekeeping. When you first get it, and about once a month after, you should drain your phone's battery completely and then charge it back up. This helps the battery, and therefore the phone, understand how much power is left with greater accuracy. If you'd like to research this subject, I suggest Battery University and Apple.
I am having horrible battery issues now, my battery is not lasting 6 hours with very light usage.
right now my usages shows
Battery 15%
4h 56m 21s on battery
media 46%
cell standby 24%
phone idle 21%
voice calls 5%
display 4%
social location2%
this is the first time i have seen media at the top of the list, usually it is cell standby that has been using the most
this has been going on since saturday, i have two batteries and it does this on both, i figure it must be an app i loaded. i dont think i have loaded anything that i didnt use on my OGDroid but one of them must be disagreeing with the Bionic. i am planning and doing a factory reset tonight (as much as i hate doing it)
any other ideas or suggestions would be greatly appreciated.

This is a 4G pitfall. You're probably going in and out of 4G/3G coverage... it may seem like a lot, but when your phone is constantly looking for 4G the battery goes QUICK. Your best bet? Turn on 3G only (cdma only) when you drive. There are widgets in the market that will take you directly to the setting.

so I did a hard reset and sent my phone back to factory default :-( and let it sit for a few hours with nothing on it except for juice plotter so i could monitor it and it was still pretty crappy I then removed everything i had copied from both SD cards (ie. photos, music and movies from my OGDroid) and let it sit for a few more hours and the batterylife improved dramatically, I am guessing there is an indexing service or a DRM service of some sort that is part of MOTOBLUR and it must have been continually hitting my cards.
today the battery life is back to normal. i have installed just a few things like friendcaster adwlauncher and a few others that i normally have and have used the phone moderately for the last 3 hours and it appears i might get another 10 - 12 hours outta of it..
does anyone know why i had issues when i put the media from my old phone onto my new one, do photos and videos have to be in a specific directory or on one of the two cards specifically??
any help would be appreciated.
Hello,
im thinking on buying the Note =]
i wanted to ask "heavy","excessive" users how is the phone battery drain ?>
*how long your phone lasts without charge (excessive,heavy use)?
*how long your phone lasts without charge (normal use)?
Im only use any of my smartphones with excessive,heavy use.
I have only 2 full battery circles and im using stock root rom/kernel.
All my phones was with very good custom kernels and lower voltages cause i wanted to stay alive during the day (8-23:00).
Now,my battery keep up the day but more easy than my previous phones (you can see which in my sign).
So, even my battery is new with few full circles, even im not using custom kernel for uc or uv, its better than my previous smartphones.
For a 5.3" display the battery life is exceeding expectations.. Based on my usage it has more battery life than the Galaxy S2 altho movie time is still the same at 8:30hrs to 9:00
I think it's very hard to define excessive vs normal use. Also the usage patterns of different people varies greatly. mostly because some use wifi on 100% of the time, others just turn it on here and there to check emails. Same for background sync and autosync which are battery drainers . So it's really hard to compare...
I keep my Wifi constantly on, background sync on, autosync is off but I have a task in Tasker to autosync every three hours manually. I have some push emails in K9 and twitter, gtalk and tapatalk syncing.
So on a day of super heavy usage the phone will last about 16-17 hours (ofcourse that includes about 7 hours of sleep time). With normal to moderate use I can make about 24-27 hours.
Hi people! I'm noob here! (wanted to write new but couldn't resist!)
I recently bought the Note and been having a few hard times with a couple of things.
One of the specifics concern battery life. Having been showered in the awesomeness of a 2,5 ma battery i thought the battery would be invulnerable but i was wrong.
The first 4 days the battery lasted me quite fine having to charge the phone once every two days. Heavy consumption was done for brief periods of 1-1:30 hours where i would try to shape my phone in the image that i wanted.
By the end of the fourth day i had a respectable amount of apps inside but not too many to explain the fact that my battery life now has decreased to 1 day.
I kinda panicked when i noticed the difference and went ahead to install Juice defender and advanced task cleaner apps. What's weird is the fact that before i did i would charge the phone before going to bed at night and then pull the plug when it would be full. By the morning the phone had lost about 25% while inert!
Noticing that i would go to the battery use feature in settings and see that the radio(!) which i hadn't been using was eating away my battery's life along with the screen which was inactive as a consequence of the phone in locked mode and a few other apps which filled the rest of the loss.
I tried to kill apps and i use Juice defender pro in custom advanced mode effectively rendering the phone dead after locking. It still consumes the same percentage of battery although now it blames the radio less and the live wallpaper more.
Am i to assume that my battery has reached it's "puberty" and that's "normal" from now on or is there a problem i just can't diagnose due to lack of experience?
This phone is my first android device. I do not know my way around it although i am learning more and more in a rapid learning curve.
Please note anything you might think has escaped my attention.
Thank you.

Your question is a little OT but i'll try to answer real quick.
25% loss of battery sounds about right if you have your Auto Sync ON.
Disable it and you'll go down to about 10% a night. Am i right or am i totally off here ?

I'll try it and see tonight. Thanks mfractal. Having been an IPhone 3G owner i gotta say, it's still kinda disheartening to see that 10% battery loss overnight is considered "normal". Will work my way around purchasing a second backup battery for emergencies.

i also come from an iphone, and yeah, you have to make some adjustments.
you can take that drain to 1-2% if you disable Background Sync.
this was my batteries first full cycle. but you should get a general idea of how it performed.

this was what i would consider 'heavy' use, atleast by my standards. Edge only, Auto sync on, brightness at 75%, fairly frequent use.
Draining twice as fast after an update on apps this morning!
Hmmm, I have been using the Note for about 2 weeks now. With Juice Defender installed (with aggressive settings), I get by OK with the battery for a full day.
Well, that was until this morning when I ran an update of a few apps, and now I barely got to noon when the battery went completely drained. Same settings on Juice Defender.
Any clues on how to deal with this? I am thinking of reverting all the updates to double check.
guys, the steps to analyze battery drain are quite standard.
Download BetterBatteryStats (there's full version for free for XDA users, search the forum)
Download CPU Spy
Charge to 100%, reset statistics in CPU Spy and let the battery drain to 10-20%.
Then Analyze wakelocks in BetterBatteryStats and you will see which programs keep your phone awake.
If you want to make sure the phone is entering sleep mode and staying there, reset cpu spy stats before going to sleep and check in the morning. more than 90% of the time the phone should be in deep sleep. If not - again, betterbatterystats's wakelocks will show you what's keeping the phone awake.

i also come from an iphone, and yeah, you have to make some adjustments.
you can take that drain to 1-2% if you disable Background Sync.

That's EXACTLY what happened! I am stunned! I left the phone last night at 97% and found it this morning at 95%!!! When i saw it i was dumbfounded!
Thank you very much mfractal!

sure NP.
problem is that background sync is required by quite a lot of programs to function correctly. Hell, market won't even open with it disabled.
My battery life is pretty good atm considering its still a new toy and gets a heavy workout.
The battery life will improve over time as my usage will drop but with the screen it pretty much can replace my pc for any basic web stuff outside off the heavy duty work only a high spec PC is good for.
Disabling background sync defeats the purpose of having a smart phone, no?

I do like my phone and the screen real estate, and understand that, it can be major battery hog. But I would really like it to be super efficient when the screen is off.
I was looking at my battery drain graphs, (Settings>About Phone>battery usage) and noticed that my phone is active almost all through the night, (even when the screen is off).
So i loose 25-30 overnight, on IDLE.
Is this normal?
I'm using Exchange instead of the Gmail app for my mail. Does that use more battery?
Regards

Of course gmail use more battery like every app running in background and syncing.
But your battery drain overnight is really so much.
The normal is 1% per hour without any app syncing in background and about 2% or 3% with background syncing apps.So you must check your apps.Something draining your battery.
Overall,i don't believe that note battery isn't good.i think Samsung haven't done so good work in filmwares and apps.
I have removed the most of Samsung apps and my battery is great.
Maybe a update from Samsung solved battery issue.In nexus previous days released a filmware update which change amazing the battery life.users mention that they loose 2% overnight.And before this update nexus battery sucks!
So, we must pray for something similar in our note from Samsung...
Sent from the best smartphone, Galaxy Note...
Do you have auto sync on? If so please turn it off and watch the drain overnight drop to about 10%
If not then we got a problem
I got my Note two weeks ago and am since struggling with my battery usage as well.
It's hard to reproduce, but Android OS is the reason for excessive battery usage when the phone is idle.
Today I found this quite interesting. Please have a look at this screenshot:
Since a few days ago I'm using Llama to control some settings on my phone, but the drainage was present before I installed Llama.
When you look at the first gap in WiFi usage you can see the phone disconnecting from my WiFi router at home (TP-Link TL-WR1043ND) when Llama disabled my WiFi.
About 20 minutes later, when I arrived at the office, Llama reactivates WiFi and my phone connects to our WiFi access point at the office (TP-Link TL-WA801ND).
At this point Android OS usage goes up considerably and it won't stop, even if I disable the phone's WiFi.
Actually at the second, larger gap in WiFi usage I disabled the WiFi connection manually which caused my phone to stay awake until I activate WiFi again.
Edit: Using Titanium Backup I have frozen Wifi-Sharing and the Wifi Manager.
Apart from that, Wifi usage was never an issue on my old Milestone, where I had Wifi enabled permanently and the battery lasted for 4-5 days.
I'd be glad to provide more information if that could help figure out the cause of AOS's battery usage.
My phone is currently running:
PDA: N7000XXKK9
PHONE: N7000XXKK5
CSC: N7000OXAKK9
I installed FM-Kernel 1.4, hoping it would fix this issue. It did for a day or so...
Apart from the kernel it's the newest 2.3.6 stock ROM I received via FOTA though.
I easily get a good day out of mine with quite a bit of use. If use mine lightly I can get 2 days out of mine. If you are in need of urgent 3G switch 3G off to GSM to conserve battery life.

Sorry, I forgot to include it in my post.
Since I got the phone I have it set to 2G only, because I used up my monthly quota and am getting throttled to GPRS speeds anyway. So the 3G connection isn't the issue either.
Apart from that this happens in flight mode as well.
Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance
I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.
Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).
I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.
Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.
@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?
Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?
Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/
I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.
I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.
Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.
What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.
The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.
Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.
I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.
This is not another, I love this phone BUT the battery is too small.
Currently there is a massive bug affecting the T-Mobile (possibly others) Galaxy S6 (unconfirmed on edge)
Symptoms
Massive Battery Drain while Idle
Cellular Standby top Usage in Battery Stats
Random WiFi issues
Self Diagnosis
Go into Battery
Tap Cellular Standby and remember the "Total Connection Time"
Go back to "Battery" and hit refresh
Check Connection Time again
If the time increases but you are NOT using any applications, on the phone or downloading you are affected by this bug.
Fixes
Turn WiFi calling OFF
Disable VoLTE (VoLTE toggle is in the Phone App/More/VoLTE.)
Update - Turning off WiFi Calling along with disabling VOLTE appears to have patched this issue for now. You can still use WiFi like normal and turn that off and on and it shouldn't have any issues.
So lets discuss this, I have not been able to fix it. WiFi on or off, WiFi calling enabled or disabled nothing seems to correct the problem. Its as if the phone is ALWAYS on a call.
Edit- VoLTE seems to have corrected the issue somewhat. What I did is turned off VoLTE, Turned off WiFi calling and then turned WiFi off and back on. My Connection Time hasnt moved since. How long this patch lasts for, I don't know.
Mods - Please monitor this thread if you could for battery naysayers and complainers. We are out to diagnose and fix the problem, not complain about it.

Thanks for starting this thread. I have tried pretty much everything, including uninstalling/disabling most apps, turning off "keep awake" for what's left, etc. I just tried turning of VoLTE and I still lost about 2% in 15 minutes with my phone just sitting on the desk (no use). My next course of action is to try a wipe. I really don't want to take this phone back. I still think this is some sort of bug with 5.01. My Nexus 6 had battery life issues until 5.1 and now it's awesome.
Okay the VoLTE trick fixed my high cell standby drain.

I've used quite a few lollipop builds and I've noticed on just about all of them (including the s6) Google play services runs pretty high. Haven't had the phone long enough to accurately test, but I'd suggest for those seeing it run pretty high to completely disable auto update of apps. That should help limit its ability to wake up the phone.

I actually disabled wake for that app using App Ops. Nothing in Gsam or regular battery stars is telling me anything.
I just performed a wipe. If that doesn't do it, I give up.
Ok guys let me throw in my 2 cents.

that was yesterday usage. I had wifi on the whole time yesterday.
Now today usage wifi off since 100%, i have no ****ing idea why facebook is using that much, ive use it 10 mins at most.
Facebook is like a hydra when it comes to app permissions. It has the most permissions to your phone with few apps to rival it. Use an app that blocks particular functions you dont use in the facebook app (GPS, contacts, etc) and just install this (must be rooted) https://play.google.com/store/apps/details?id=com.findsdk.apppermission&hl=en
I realize it hasn't been a full days of use yet, but the Cell standby sums up the battery issue drain. I'd prefer to keep VoLTE on, and we should be able to without this being a problem. It was on, on my G3 and I didn't have such significant Cell standby battery drain. Any idea of another cause?
So, I finally caved in and wiped, even though I have had the device since Monday and battery has been bad all along. Prior to wiping, I was losing around 2%/15 minutes (8-10%/hr) without even using it. After wiping, seem to be losing around 4%/hr. I am not using it at all, just testing the idle drain. It's definitely better.
My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

For me, even without ever turning on my phone, it's syncing with breaking news apps, facebook, twitter, hangouts, gmail push, work email push, a couple online RPG games pushing me alerts and so on. My battery drain ironically isn't stemming from apps syncing and emails/alerts being pushed constantly throughout the day. It's the cell standby for me.
contributing factor?
http://forum.xda-developers.com/galaxy-s6/help/flash-lit-t3069039
Seems to be the cell standby for me too. Disabling WiFi calling and VoLTE has fixed it for now.
Is there a Samsung support channel where we could get this recognized? It seems really asinine that people are exchanging the handset for what is clearly a software defect.

VoLTE seems to be my problem for now. Disabled it. And fully charged it to 100% and its now at 75% and cell standby isn't even on the battery stats list.

So, I can't believe I'm saying this, but a factory reset totally resolved my battery issue. It was only 4 days old. I couldn't see how it could have possibly been fixed by that, but it was a last resort before returning it.
Now I have some pretty normal Battery life. I love this phone!

If you hadn't been a douche in your follow-up reply, I certainty would consider it.
Having this issue as well..after having a nice battery cycle of almost 5 hours sot I'm seeing the same thing in bbs, losing 6% an hour idle. Will try the fixes to see if it helps thanks guys
so im getting the edge on the 15th
should i factory reset it right when i get it ?
The only thing I did out off the box was take the OTA and root. Maybe the OTA set it off? I pretty much have the same apps installed now.

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

you might have some apps draining battery. I'm used to a rooted phone, so I'd always check with wakelock detector, but I'm not sure what you can do without installing an app as a system app.
Try factory resetting your phone and using it without installing anything for a day and see what the battery life is like. If it's significantly better, install your apps 1 by 1 until you find out which one is causing unnecessary cpu cycles or wakelocks.

But I wonder, I shouldn't see the heavy usage on the battery info page? Like which app does most of the usage and time spend in the background or CPU?
I had excessive battery drain, about 10-11% an hour with every off . A full factory reset cured the problem.
What's your screen on time usage? 5-6 is probably the normal amount you would get with most phones (This is the most important thing if nothings draining the battery). And yes, it seems you might need a factory reset.

You won't always see this as it could be a byproduct causing a kernel wakelock.
Either way, something is acting incorrectly. The only way to really figure it out is to start over and try things slowly till you find out what it is.
For instance, on my nvidia shield tablet k-1, I was getting horrendous battery life on every single rom, stock or AOSP/Lineage. I found that I was getting 30% wakelock killing ~20% battery life per day when it should be sub 5%. I found that wifi was causing these kernel wakelocks and setting wifi to be disabled with the screen off unless charging fixed the issue entirely.
Now, that anecdote likely has nothing to do with what you're experiencing, but note that you can usually find out what's wrong from trial and error.
I've had my note 8 for 6 days now, and battery life is excellent, i mean i have wi-fi and 4g lte on all the time, bluetooth on all the time, sync with 3 emails, Facebook, weather widget, weather screen refresh every 30mins, location high accuracy, edge lighting, aod schedule 7pm-7am, was 100% at 6am, played games on it lots, used the phone 2x, 1 hour call and a 30 mins call, text messages, it's 130pm and I'm at 55%, try a factory reset then log in to your gmail then just try to update the phone if there is any. Then reboot then start installing your apps. If it doesn't work call carrier customer service and complain about the battery not holding up like some people you know who has note 8. They might replace it with a new one.

What's your screen on time usage? 5-6 is probably the normal amount you would get with most phones (This is the most important thing if nothings draining the battery). And yes, it seems you might need a factory reset.

Phone died 15-20 minutes after I did the screenshots, so a bit more than 2 hours...
So.. yeah.. I will try a factory reset and start install all the apps bit by bit and see which one causes the troubles.. hopefully is nothing more than that.
Did you restore a backup or did you load your apps fresh from the play store?
I've had horrible luck with issues like battery life restoring from backups. I always install apps fresh.

I did a google restore from backup! Damn! And I was thinking that I should maybe to a clean, one by one app install.
My battery life is also not great but im using full resolution and when i remember time when i got S6 edge on launch....the battery was horrible but after few updates it was perfect so stay strong and wait a bit

can you translate "not great" in hours? :laugh: Because I will say that mine is second after horrible.. with update done.
I will start the reset in a short while and I will test it tomorrow with minimum apps installed.. those which I really must have in a working day..
Maximum 5 hrs on wifi normally about 3-4 battery is not great on note yet....some optimalization would be nice
I use Ampere to monitor the instan drain of current. In a quiet situation (screen on, internet or tapatalk browsing, gear connected, wifi and data turned on) you should have something 200 mA drain.

Maybe some of the settings changes you're making are somehow rendering your phone less efficient.
I have the USA unlocked version and use it as it came without changing to a dark theme or turning anything off and the battery life is much better than yours.

I restored from a helium backup. My battery life wasn't good for about a week but it did last all day down to 20-30% at the end of the day. After a week it has improved maybe due to apps updating. Now I'm at 70-80% at the end of the day with moderate use. I have disabled several apps I didn't need as well.
Seems like it's hit or miss with the battery life. I see a lot of people happy and some are having problems. Hopefully Samsung might push a update to help.
Get cpu spy and verify that your devoce is going into deep sleep when off(mine wasnt at first until i froze/removed some rouge apps). Install accubattery and do a benchmark and see how your battery does. At least do 6 discharge cycles first to see an average. Also, in device maintenance, you can make all apps doze when not being used now.. this is a new feature. Add all of your apps and they get put to sleep immediately. I get 8 hours SOT this way

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

You dont have to use med battery saver either, just read my reply on this thread and you will be good. You may have to experiment a little to get your device to go into deep sleep when screen off. Mine didnt at first. Its on my other comment

I got back from work and my phone was at 75% that's between 9:30am and 6:30 pm. So my battery life is pretty good. I lose about 5% overnight.
I average 7hrs screen time Got 8hrs yesterday
