Hi everyone,
most of the time, my Axon 7 eats the battery absurdly fast, when only lying around (Standby). I opened a different thread that I caught it once discharging the battery even when turned off, but several other times, it did not do that again.
I noticed that BetterBatteryStats tells me that there is almost 0 time for "Deep Sleep" (3s) while it is "Awake (Screen Off)" almost all the time. Since I have no root, I do not know how reliable the data is (100% Awake + 21% Screen On + 0% Deep Sleep = 121% = lol).
I have checked the power management for all apps. All have "Allow deep sleep" activated.
The battery discharging is so heavy that one charge is not enough for one day of usage (with some hours screen on time).
Do you have experienced something like this, even with a different phone? Any ideas are welcome.
Regards,
Puni
You must have some app eating your battery. Try to remove some latest apps and reboot. If that doesn't work clear cache.. After that is only factory reset left...

Okay, this is not really specific to the Axon 7, but it will work anyway. I precise I'm NOT ROOTED as well.
First :
- you better also install Gsam Battery Monitor, you'll have access to a better looking stats for Doze Mode. However, under Battery Manager (sorry, doesn't know how it is in english) / Battery Usage / Time battery used, you should have "Awake time" and monitor it here as well
- install Greenify as well, to try to apply Doze mode asap.
Second:
- Wifi on the axon, even when "turned off while screen is off", isn't. Manually switch the wifi off if needed.
- The same is for the GPS/Location services. Even when the toggle is OFF, you are still being tracked. Long-clic on the toggle, and make sure location is disabled (unless you need it). It will reset if you 'allow' Google Maps to enable location for yourself. Don't do it.
Third :
- Fiddle with Energy management, and learn about the 4 available toggles (disallow at startup, force close when screen is off, delay wake up, do not allow wakeup when in doze mode). Be careful about notifications tho, activating some switches might remove or delay them
- Go to security, administrators : do you have an app that shouldn't be there (which can wake up the phone)?
- Go to acessibility, same
- Do a reboot
- Watch what happens next
- Please report back here with BBStats + Gsam + Energy manager screenshots at least
Thanks a lot!
I will try your hints.
But disabling Wifi and GPS/Location is not really useful for me, because I need both all of the time. Could try it for seeing if it helps though.
Activating Air Plane mode allows Deep Sleep. Not useful, but nevertheless interesting.
I noticed that my Medion tablet with Android 4.4.2 (!) has the same issue. Must be an app installed on both I guess.
Wakelock Detector says it's Android System, AlarmManager. That is not too helpful.
On my Axon 7, Bluetooth triggers the Wakelock. It's 100% reproducible. Cannot be the whole story though, there must be more. The battery lasts at least twice as long without Bluetooth.
Solved!
Solved it!
It was the app MeinVodafone. It causes Wakelocks when Bluetooth is enabled.
I found a forum posting by somebody else confirming that.
Very nasty.
Thanks everybody!
P.S.: My tablet is a different story. Bluetooth is never active there. The wakelock vanished, but I have no idea what happened. Doesn't matter, unrelated.

Ok, so I've noticed odd battery drain when the tablet isn't docked but in standby with WiFi off when screen off..
There are other threads/posts detailing how we can use CPU Spy and Titanium to "freeze" apps that may be cause battery drain in this scenario however the question I want to ask is.. just how accurate is the info in the Settings -> About -> Battery page? It lists apps/processes/services that have been using power but I often get things listed there that I never knowingly started, and certainly they don't always appear..
An example was recently I've been seeing entries for IM+ (which I installed but rarely use) and Media Server (I'm assuming this to be the Asus MyNet? Again, never used).
After a recharge and reboot.. the battery stats page seems to reset to some starting condition, usually listing Wifi, Screen and tablet idle as the main things. Then, after some time in standby (say overnight) those other items mysteriously appear (and for some reason the battery graph shows activity against WiFi and Awake even though I'm using that WiFi power saving mode AND when I wake the tablet up, the WiFi is indeed disconnected and CPU spy shows Deep Sleep)
..So last night I uninstalled IM+ and this morning I have Widgetsoid listed in the Battery Usage page.. something that's never listed there before... what gives? Its completely inconsistent.. sometimes overnight I'll get virtually no battery drain, and sometimes I do.. there's no pattern to it and no app/widget/process I can pin it down to, to freeze (not that I should have to but I appreciate that many have found this to be the only sure solution)
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.
When keeping my phone on idle during the night, it dropped by around 30%.
I have installed BetterBatteryStats.
The largest user of the battery is "Android OS", according to the battery graph in the settings menu. However, in BBS, the largest partial wakelock is Connectivity Service, which was on for only ~6 minutes.
However, under CPU states, it says that the CPU was idling at 250 MHz for many hours?
This is undoubtedly some sort of phantom battery drain. It has occured for many weeks during the use of the phone.
In addition, with 'Wakelock Detector', it too says that the largest wakelock is usually for around 6 minutes, by Facebook more often that not. However, the total stats say that the phone was awake the entire time, and it has not entered Deep Sleep at all.
I would greatly appreciate your help and tips. Thanks

You could try ds battery saver from Google play i use it and loose about 3% over night 7 hours
Yeah this looks weird.
I'm no BBS expert, but what I would do is, disable everything. Weather widgets and so on, Facebook sync and whatever else you have syncing in the background. Basically make it a dumb phone temporarily by disabling all the stuff you have running.
Then reboot and let it sit for an hour without touching it.
Check BBS again, choose "since boot" and look for partial wakelocks and battery consumption.
If it seems OK, turn something back on, for example add a weather widget and enable Facebook sync again. Don't enable too many things, just one or two! Reboot. Let it sit for an hour without touching it. Check BBS again. If the result now is again worse than it was before, you know that something you just added or enabled is causing the drain.
If everything seems OK, enable something else, whatever it may be - an RSS reader syncing, Instagram, Flipboard, Skype - I don't know what you have on your phone. Reboot and let it sit, check BBS again.
10 hours of WiFi on and WiFi running. There's your phantom drain.
Let me guess, you have scanning enabled in Wifi settings?

Thanks for the detailed advice. I'll disable everything, reboot, and then keep it for the night. And I'll install DS Battery Saver.

Nope, I'm afraid not.
UPDATE
I did as you advised before, disabling everything. The drop over the night was only 10% this time, but this inexplicable drop persists nevertheless.
I had the same thing happening yesterday night. When my phone is drained, I usually charge it in the evening, reboot and then let it sit for about 5-6 hrs with everything except NFC off. Normally, I have a battery drop within those 5-6 hrs of about 1-3%. But yesterday morning after the same procedure, I had lost 30%. I did a reboot then and battery usage went back to normal. So I charged my phone yesterday night and did a reboot, and surely enough I only had 1-3% of battery lost over night. Strange.
For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274
I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...
Use wakelock detector

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
Hey guys...
Just here to say that I unplugged this phone at around 5 in the morning, and around 5 hours later its already down to 74%.
What did I do? Only about 10 minutes of mobile hotspot, a 2 minute phone call, and three text messages. The rest just idling...
1/4th of my battery life for just that?
What the heck?
Everything is disabled and the screen brightness is low... Whats the matter with this phone?
Looks like something is keeping your device awake.
Can you please add some screenshots of your battery graph?
In addition, you can try to boot into safe mode. If your problem is gone in safe mode, a third party app is interfering.
If you're rooted, try installing Wakelock detector or BBS (Better Battery Stats) and check out what is waking up your device.
If you use Gas Buddy, it was known to be causing massive bluetooth wakelocks. Either uninstall it or update it to the latest version.
Set your wifi to 2.4 ghz only. On 6.0 and 6.0.1, the 5 ghz band has been causing abnormal battery drain and keeping phones from entering doze mode. Here's the issue being reported: https://code.google.com/p/android/issues/detail?id=197460
If neither of these make a big improvement, you'll have to use your battery stats (and if rooted, use Better Battery Stats or Wakelock Detector) to specifically see what's keeping the phone awake. In either of these apps, filter the view by "Alarms" or "wakeup triggers" and you'll see what the heavy hitters are.
Be sure to go into Location>Settings and turn off wifi and bluetooth scanning.
Hi.the maps app isvuding WiFi and gps even though both are disabled and I'm not using it... Any ideas?
