I have seen many posts about the poor battery life on the ADAM when in heavy/normal use. I have seen very bad battery drain just in standby/sleep on all the roms I have tested (Stock Newest build, edenx, and now CM7). SetCpu currently doesn't support profiles but I wonder if the processor still runs heavily even when in standby.
I should note that i usually turn off WIFI when not in use and also background data sync.
Pixel Qi Wifi.
As usual, after unplugging the device in the morning and not touching it for 8+ hours, it has about 50% battery left and battery history shows Phone Standby using all the battery. I guess these quirks will not be resolved until Honeycomb if ever.
Which do you mean "cell standby" or "phone idle"? I have the same model and the battery still drains more than expect overnight, but notas much as 50%. Did you apply a fix to remove cell standby?
Phone idle is what is reported. Here is a more specific example: on battery power for 10 hours today in standby with wifi off and background sync off and the battey is down to 55%. This is not a huge problem but I dont like to leave it on the charger constantly when not in use.
Kill the "phone Idle" <- that's really draining and if you don't use SIP on a WiFi only you can de-install phone and phoneprovider
2 other things you could try,
Install from the market:
"autokiller memory optimizer" and
"Juice defender"
They seem to help for me.
or use BEAST ROM 2.2. My ADAM batterie status is after 23 hours on 36%.
My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.
Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.
Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.
Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??
You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.
Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.
Image (BetterBatteryStats): http://antti.vahtera.org/images/SC20111221-020623.png
CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?
Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.
I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note
I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.
Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?
Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.
Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?
It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.
This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.
I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.
My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.
had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..
To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.
To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.
i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call
I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.
Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.
Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.
Ok and which stock rom does not do that?

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.
I have a new Samsung S4. Trying to learn how best to configure it to minimise battery usage and to ensure I don't install apps that eat battery. There's nothing wrong with it, battery usage is fine, just trying to get the best out of it; whilst keeping as much functionality as possible without having to constantly turn things on and off. I'm trying to avoid rooting it.
As a starting point, I'm checking usage overnight, when blocking mode and power saving are on, with wi-fi and data off; but with the alarm clock set.
I have an i-onik 7.85" tablet on Android 4.2.2 - with a deep sleep battery saver app set to slumberer ("always deep sleep when screen off") it only uses about 2% of battery overnight - the battery currently holds about 3600 mAh - so that 3% equates to 108mAh.
First time I tested my Samsung S4 (the european LTE version 9505), (actually I think I had wifi, data, location setting turned on and power saving turned off), it used 4% battery overnight. Not bad, 4% of 2600 mAh is 104 mAh. Still I thought I might do better. I tried the deep sleep app on slumberer but inexplicably the usage then jumped to 12% (whereas it at least halves battery usage on my tablet). I've since un-installed deep sleep battery saver and started turning off wi-fi, data, and turning on power saving - so I'd expect it to use 4% or less battery overnight.
The actual battery usage instead increased to around 9% to 12% - although the settings used might have varied.
Three nights ago I made sure that all apps were closed, and everything turned off as above - battery usage overnight was still 9%. I used WakeLock Detector and found that a Morrisons App was causing wakelocks. I uninstalled that, and the next night the battery usages was down to 6% with much fewer wakelocks. Still not as good as before though.
I then found there were wakelocks due hotmail and gmail sync - hotmail I changed from push sync to sync every 4 hours, gmail I changed from hourly sync to manual sync and I also turned off master sync. I also turned off location setting. That cleared the wakelocks for these apps, but battery usage last night had increased to 9%.
So, despite the same settings and less wakelocks (and it was in deep sleep all night except for 16 minutes), battery usage increased from 6% to 9% - still no where near the 4% I had at the start despite making various changes that should reduce battery consumption.
The only significant wakelocks last night were:
com.domobile.applock (via alarmManager) awake 35s giving 992 cpu wakelocks
com.google.android.google (google app) 7 wakeups
Can anyone think of any cause for increased battery usage from 6% to 9% despite more time in deepsleep, less wakelocks (other than the 2 above but there were many more wakelocks the night before lasting several minutes) and location setting turned off. I wonder about starting again from a factory reset ... NB every night before going to bed I've rebooted the phone, and charged it to between 90% and 96% and it's been tested over the same period of time. Is it normal for battery usage when the phone is sleeping to vary so much?
Charging the battery inconsistently might lower the battery life. And letting it discharge to much does the same. I generally avoid letting it go under 50% and unplugging it before 100%.
I don't know what causes your issues, but if you want full control over your phone, you will have to root.
I also had 2% drain over night at some point, but now I have 4%. But this may also be rom related.
Thanks. I'm on stock ROM. I have rooted other devices but then find some apps don't work, and of course I want to maintain my warranty.
Each day my battery is generally dropping to about 30% at which point I charge it up to between 90% and 95% before turning turning most things off ready for bed.
At some point I may leave it plugged in overnight instead - is that a bad thing?
What do you mean by charging inconsistently? Sometimes my battery may be around 50% though more often around 30% when I start it charging.

By charging inconsistently I mean exactly what you said. You charge between 90 and 95% generally, instead of leaving it to charge 100%.
Somebody said that if you live in the EU you will not lose your consumer rights. I guess that includes the right to have your phone repaired because it is in warranty. Other people have reported that the phone service accepted and repaired their phone even though it had knox flag 0x1.
There isn't much you can do on stock unrooted roms in order to reduce battery consumption.
You battery drain is probably caused by weak signal strength. Having bad signal uses more battery. The screen and the phone radio use the most power on the phone. If you put our phone in airplane mode there should be almost no battery loss. If everything is turned off.
On my old device I used to put in airplane mode during the night. I had 0% drain over night in airplane mode.

Thanks - that's a good point about signal - my mobile signal and wi-fi signal does seem to vary, so that could contribute to fluctuating battery usage. I decided to test that by using airplane mode and have started charging to 100% on your advice. Unfortunately when trying to dismiss the prompt to upgrade to lollipop, I accidentally started the upgrade, with no way to cancel it. (For me, lollipop really seems a downgrade, I've lost a lot of functionality I used all the time in KitKat).
The bad news it that on lollipop overnight last night, despite using power saving mode and airplane mode, and basically everything else off including sync, it lost 7% of battery.
So I decided to do a factory reset, thinking it would go back to KitKat - but it didn't - it stayed on lollipop. It did give me the option to choose which extra apps to install (including some Samsung ones) - I declined to install any extra apps, and also turned off automatic app updates - I then turned off sync, backup and anything else that I thought might eat battery - leaving the phone with the most basic set up possible. I've not since installed any apps except Talk2Go.
The good news it that since the "factory reset" to lollipop, I've tested it for two periods of 4.5 hours on airplane mode, everything off, and I did not turn on power saving mode. The battery lost less than 1% - in fact for my last test it stayed at 100%. So either the reset fixed battery loss on lollipop, or the power saving mode was actually causing battery loss!
I'll investigate that and report back for the benefit of other users. I'll then gradually update my settings and see what, if anything causes battery usage to increase when on airplane mode. Of course it's also possible that battery usage might increase without changing anything, as per some reports from those upgraded to Lollipop - if so I'll report on that - and confirm if a reset seems fixes it.
Lollipop is supposed to have a battery saver mode - but it seems to be missing in the stock OTA update to S4 - does anyone know how to use this mode? It sounds better than Samsung's own power saving mode (especially since that might actually be causing battery drain rather than saving battery!)

Samsung probably replaced the stock lollipop battery saver with their own battery saver.
You could return to kitkat by flashing via Odin. Doing so will not give you knox status 0x1 and you don't even need root.
On second thought, you have the new bootloader so you probably won't be able to do it without tripping knox..
From what I saw, battery saver changes only the minimum screen brightness to a lower value than normal and it changes the CPU governor to a more battery friendly one.
This is what I observed on the GPE rom battery saver mode.
Testing continues - for the first few nights battery drain was less than 2% on airplane mode, but it wasn't repeated last night. It drained 9% with exactly the same settings (ie everything off except the alarm clock, no foreground processes running and airplane mode on).
I've installed a few apps - one from TalkTalk, one from Three Mobile, a terminal emulator and wakelocks detector. So have now uinstalled the first 2 to see if they are causing the drain - BUT I suspect it's a bug in this release of Android Lollipop.

Many people have problems with the stock lollipop. Samsung messed up.
It might also be the battery. I have my phone since november. My battery used to drain 2% over night. Now it drains 4% over night. Basically it drains very fast to 96%, from there it drains normaly, depending on the usage. This happens on every rom I tried and with even the most battery oriented settings.
You seem to be using applock. If you don't need it you can delete it and get rid of a few wakelocks.
We all know the battery was perfect with M, we all know that since N battery drains way faster, but I've gotten used to that.. Instead of 5 SOT I got 3.5. Ok.
But now.. I hardly go past 2. Battery drains really fast, it's not even stable. Doze doesn't seem to work anymore, percentage drops each minute and a half, and now.. phone shuts down at 6% all the time. What should I do?

We all know the battery was perfect with M, we all know that since N battery drains way faster, but I've gotten used to that.. Instead of 5 SOT I got 3.5. Ok.
But now.. I hardly go past 2. Battery drains really fast, it's not even stable. Doze doesn't seem to work anymore, percentage drops each minute and a half, and now.. phone shuts down at 6% all the time. What should I do?

You could install GSAM and see if it's an app causing the issue. You can also try turning bluetooth off completely for a day or two to see if that's a cause.
Worse case, you can do a full factory image re-flash. In my past experiences, most of the time, updating OS major versions never sat to well with my phone. I personally do a full factory flash-all after every major update.

I have GSAM but since N it doesn't show stats for specific apps but only combined. As for Bluetooth, it's never on.

Well that narrows it a little more than.
Actually, with a recent update, you can see now.
If you go to Enable More Stats, it will give you directions. I believe you need a file explorer, move one file to another location, and rename that file.
Software fault. The battery doesn't really charge fully, I've noticed that when my phone froze (literally) and it was on on 50%. I warm it up, says 1%.
After that my battery life is exactly half, which means that 1% is actually my 50% but the phone sees it as empty.
Check battery capacity with accubattery. Not completely accurate but it does give you a ballpark range. If the current capacity is way less than the specified spec, then you have a degraded battery
I agree with the Accubattery approach (or similar app) to measure the battery capacity. Several ppl have experienced degraded batteries.

I've done a factory reset, Accubattery shows 3022 out of 3450 mAh and 88% of battery health. Do I need to replace the battery?

Not unless you can get Huawei or Google to do it for free. I haven't seen any new genuine oem replacement batteries. They are either used or fakes that don't work right. Some don't even have a temp sensor. Accubattery shows 2876mAh for me and I get 4.5 to 5 hours sot on 6.0.1. Same as I ever got. After installing 7.1.1 with full wipe from factory image, same settings, same apps, same signal, same usage, I get 3-3.5 sot. On nougat my phone would intermittent turn off under 15%. Hasn't happened once since I rolled back to marshmallow 2 weeks ago. Either some people (like me) are using certain apps that consume battery without it showing on gsam and better battery stats, or nougat just uses more battery when the screen is on. I believe the latter.

I wouldn't think so based on that snapshot. I'd keep running the capacity test (documentation states accuracy is improved with time) and start looking very closely at individual services and apps for anomalies. If rooting is an option for you, wakelock and battery statistic tools are better able to return more accurate data than non-root apps. Absent any rogue apps or services, monitoring the capacity will give you a trend and likely answer your question about replacing the battery.

Ok, good to know.
Can you please follow this order of events?
1. The battery was as I've noted at the beginning of the post, drains fast and shuts down at 6%
2. I've had a factory reset.
3. I turned on the phone, clean and wiped, at 35%. It took me 1:29 hours to get from 35% to 7% [which is great!] but then at 6% it shut down again.
4. I turned it on right after, it showed 1%. It lasted for another 10 minutes of usage.
5. I charged it to 100%.
6. Then, when the screen is off, battery loses 2% per hour, and when I use it, it loses 1% every 3-4 minutes [which is great], BUT - sometimes it loses 2% at a time, say 80 to 78 and so on. I still don't know if the phone is gonna shut down at 6% or if it was already fixed.
Does that seem normal?

It doesn't seem normal to me. Neither the 6% shut down nor the increased battery drain. As I said, I had both issues to some degree, early shutdown, and much less screen on time. Since a switch to 6.0.1 fixed both issues I am lead to believe they are software problems, not hardware. Google responded on reddit that they are looking into the early shutdown issue about 10 days ago. Then there is also the sudden influx of bootloops of death after Nougat. My advice is to use Marshmallow until things become more stable.
You could go into accounts-Google and see if there are any syncing errors.. Facebook and Facebook Messenger are both known to cause big battery drains on Nougat. Gas Buddy used to be a problem as well but not sure if it still is. As another person suggested doing a full flash-all.bat clean install might fix your problem. Some people just go back to Marshmallow,
