What ROM are you using? Your wake seems unreal, like it never sleeps.
.: Swyped from my Samsung Galaxy S II™ Epic™ 4G Touch ლ(ಠ益ಠ)ლ :.

1. Turn off Auto Brightness - Menu>Settings>Display>Brightness
2. Lower Brightness - Menu>Settings>Display>Brightness
3. Turn down screen - Menu>Settings>Display>Screen Timeout
4. Drain your battery until it turns off automatically.
5. Keep it off, charge phone to 100%.
6. Repeat steps 4 and 5 two times.
Use device like this for 48 hours, then post back your results...
Tips:
Keep WiFi, 3G, & 4G off when not in use.
Press the power button to turn off your screen when not in use, (don't hold...)

I'm running stock rom. It just started doing this recently. About the time I started moving apps to the sd card. That's the only thing I could think of. I know when I put too many apps on sd card my phone will go into a continuous boot loop. I'm going to move everything back to the phone and see what happens

1-3 are pretty much all set. I don't use auto brightness. 4-6 I've done before but I will do it again. And I keep radios off when not in use so that can't be it either. My phone used to have good battery life with the settings I normally use so I don't know what's causing this all of a sudden..

The thing that bugs me is that display time is so high in % and it only was on for 22 mins. Then I took a nap and it stood at the top. Usually my Android OS takes the top spot when phone is not in use. This is mad weird! But i'm trying both things now..

What is media server? I don't think that used to pop up b4 and its always on my battery stat as of recently.

has to do with WiFi, as connecting to the Network for music, and Kies, (I believe)

I don't have wifi at home anymore so I keep wifi off. Hmm.. Can it be from running the Sprint hotspot? I used it last night and haven't rebooted phone since using it. I use it almost every day..

possibly.... I'm not quite sure, to be quite honest...

Your phone was awake the entire time while your screen was not. That means you have a serious wakelock issue. To find out what is causing it, download betterbatterystats, and that will tell you what program/process is causing such a long partial wakelock. Seriously helped my battery issues big time.

[Q] Wrong stats on Bluetooth activity

Hello, i'm using betterbatterystats to check my battery life.
Everything is OK but i have a strange behaviour.
The App says that my bluetooth is always ON

}
but my Bluetooth is always OFF :
and i double checked in Parameters, and even restarted my phone, still same problem ....
Then today i checked my batterys stats and i get this :
My log is 19h10m5s long, and i have 2% of Bluetooth time.
But when i look at bluetooth time it says also 19h10m5s
so it should be 100 %, shouldn't it ?
Anybody also experiencing these strange Bluetooth stats ?
My Bluetooth is ON or OFF ?
Thanks.

battery stats doesn't really work, looking about the forums you see if you put wifi on all the time it says you have No or unknown signal for the same time as wifi was on.
you can look at your own screen shot for this one
seems it doesn't report as it should on the HOX

Hi, it is quite sure that betterbatterystats doesn't work but it's the system logs which is in fault not the app itself.
Even the stock app shows strange values on Bluetooth and wifi as you mentioned ...
In the case of the One X it is very useful to read those stats, but if they are totally wrong, how can we do a correct analysis of battery drain ...
By chance it is rarely bluetooth or wifi that drains the battery.

apagado es mejor!!!

19+ hours on battery with 65% left, and you call that a drain?

Hello, i have no drain, and never said that.
I just noticed those strange bluetooth stats when checking battery usage ...

Can you disable widget locker and associated power widgets in you home screens and figure out?
I would imagine some kind of interaction comes into the equation with these 3rd party programs.
Bonne chance.

Hello, thanks, it is a good idea ...
I removed the power widget on the home page and disabled widget locker.
I restarted my phone. Weirdly i had to insist to restart the phone.
When pushing power button, after 3 seconds, the lower buttons were blinking
but it didn't start, and then keeping power button 3 ou 5 seconds longer the phone restarted .
That is not the first time i noticed that the phone doesn't start or stop normally ...
At restart, i didn't see 100 % "bluetooth on" in betterbatterystats.
It looks like problem is solved ...
I will let the phone like that for a moment and put again the power widget on home page to see if i get the error back.
And then activate back widget locker.
Merci.

I activated the bluetooth for some minutes and turned it off.
Now i see on betterbatterystats that it is still ON in stats.
I refresh and the time "bluetooth on" is increasing.
I will wait a moment to see if bluetooth appears on "stock" battery stats.
It looks like a android system issue with bluetooth stats

[Q] Battery drain question

So, when i updated to official JB , i immediately went abroad, so i didn't have access to packet data. When i returned home, and when i turned on packet data, i am getting higher battery drain. I am not turning off packet data at all because i was used to that. Can that be the cause of my higher battery drain. Syncs are turned on, also auto update on weather..
Here is screenshot of battery details. You could see that i charged it a bit atm cause i need battery to write this thread. You can also see that i used a bit of wifi.

Most of us are now seeing higher drain on JB exactly like your pics show. That's how mine looks too. Look at all the awake lines. I just assume its because I'm now running Google now. I've been planning to turn it off and test but just been lazy. On ICS my idle battery was dead flat and showed not a single awake line.

even im facing the same battery is pathetic
is there any way to increase ??

I swiched to Android Revolution HD 6.0.1 (with JB 4.1.1) ans since then I have a higher drain on my phone.
The strange thing is I have a lower, wehn I turn it off, but a much higher when I'm using it for browsing or anything connected with the screen.
It seems that either the changings have a higher usage on the graphic area or that (somehow) the screen uses more power.
I have noFrissl installed , and it tells me that most of the time the CPU is at 350MHz, so this can't be the reason.
Anytime I use the screen (by an app (even without internet)) it sucks the battery faster dry than at 4.0.4
I'd appriciate a solution and to be able to use my phone more than just 1.5 days (but more the two days I had before)

Ok this is the thing:
When i use my phone modest, i have great battery life. It means that im using wifi for half of the day, using it for taking photos, playing some games etc. As soon as i turn on mobile data network, i have higher battery drain...

I would agree with this comment. For me...mobile data always is a battery killer. I always use WIFI over it and turn off my 3G unless I need it. I save a ton of battery life. Your phone always is gonna have more significant drain hunting for towers and for a good signal. It sucks, but it is what it is.

Hi everyone,
I dont have this great battery drain, using always mobile data on and wifi when i'm on home.
The first thing you can do for better battery is install franco kernel r230-jb or Fugumod ( <3 ) kernel, this help alot with consumption and have no negative effect.
second thing is remove haxsync or facebook app , using tweakdeck ( support facebook&twitter ) or only one ( Facebook ) or mobile browser ( no update ) , its more less battery expansive.man with that usage, you are very lucky with this battery life, you have a lot of ~45% screen on ( ~4-5 hours ) with 8% facebook cpu usage, and ~8% haxsync , and some calls, of course battery go down so fast
another suggestion is always stay on 2g, switch on 3g(4g?) only when need ( for me never, because i use twitter/pulse/facebook update/web, twitter go good also 2g network data, pulse too, facebook is extremly low, but update and notification work, web is fast with Opera Mini.
No problem at all.
ALWAYS REMOVE GOOGLE NOW, ITS USELESS AND THE FIRST CAUSE OF BATTERY DRAIN

A great explanation of the msm_hsic_host wakelock issue by "thracemerin" on the xda-dev forum
I didnt understand the issue previously, but this sheds light on it for me.. http://forum.xda-developers.com/showthread.php?t=2155461
"The msm_hsic_host wakelock is because the 3G modem is connected to the phone as an external USB device controlled by the hsic host controller. When the modem wakes up for any reason (apps sync, location, tower ping, etc...) the wakelock is requested. The problem is that the hsic host controller doesn't go back into suspend mode properly, this is a problem with the kernel. The result is that because the hsic host controller isn't asleep the phone wont enter deep sleep while it waits for the hsic host to suspend.
There is the additional issue that if your signal is poor the operations that caused the wakelock in the first place take longer to complete thus lengthening the time the wakelock is held.
The issue is significantly reduced on WiFi for obvious reasons, all the data is transmitted via WiFi so the 3G modem doesn't need to wake up nearly as often, it still wakes up to deal with tower checks and that sort of thing to ensure that it has voice connectivity, but those events are much rarer.
There are kernels available that attempt to solve this problem, Harsh kernel as suggested by another user has fixes in it along with a lot of other changes, the fixed kernel I'm working on is stock with these changes as well, either should help, it's not possible to eliminate this wakelock completely without shutting down the 3G modem which would of course prevent data and voice use of the phone, but they will reduce the wakelock and may help with your battery life."
http://www.reddit.com/r/nexus4/comments/199bd3/a_great_explanation_of_the_msm_hsic_host_wakelock/
So? How Sony will handle this?

I thought this was already fixed by Google in mainline kernel, this issue is pretty old one.
Remember, this wakelock is not possible to eliminate completely, it's pretty much the synonym to your phone receiving/transmitting any kind of network traffic over 3G. And lot of apps cause regular incoming packets each of which will wake up the phone. That's why to big extent Sony introduced Stamina mode.

Well for me it was busy for 21m8sec on 5h29h of idling. Phone was on WIFI all the time.

Phone was on Wi-Fi, but you don't have Wi-Fi set to be on only when screen on do you? Also, maybe you've enabled "use only good Wi-Fi connections?" As for myself I see noticeable time in this wakelock only when away from Wi-Fi

Try switching mobile data off completely.
Maybe your operator sending you ping packets regularly or something like that.

Just try it out.
Also, if you have Google Now on, switch it off.

Check out wake lock time ratio... My battery is getting killed I run stock 4.3.

Uhm... I've updated my kernel with the latest release from Ziddey (which uses Franco's as a base and adds USB OTG support).
After that I noticed this problem. I've noticed it in the past and fixed it by reflashing a previous version, so I restored a previous kernel but the problem remained.
So, in an attempt to understand what was causing the problem I reinstalled the latest kernel again, only this time not fixing the permissions after flashing it. The problem seemed to be gone. I realized that every time I've had the problem in the past it was after fixing the permissions in TWRP (it asks if I want to fix permissions before reboot every time I flash a new kernel).
Could it be only a weird coincidence?
BTW, I usually never fixed the permissions because I thought it was a TWRP bug/mistake.
I'm doing some tests right now.
[EDIT] P.S. I know it's unlikely that's the culprit of the problem... But...

Hi. I bought this phone for my wife a few years back and recently she told me her battery was draining so I installed Better Battery Stats and found out the same wakelock issue in this post. She is using latest stock rom and the issue happens even if on wifi. I can't seem to find any other information about this issue. Any ideas?
BTW, sorry for necro.

Sudden Major battery drain on Note 4!

I took my note 4 off the charger this morning and used it for about 1.5 hours (no videos, just tapatalk and Web browsing) , and the battery went down to 73%. During this time I also noticed that my wifi toggle was turning off and on for no reason. I don't have smart network control check on.
Then I went about my day and set my phone down, asleep, and didn't touch it. At 11am I hear the "low battery" beep. I go over to my phone and it's at 5%!
My battery has never been this bad before, and this just started today with no app changes. As I'm typing this, my phone went from 20% to 16%.
Is anyone else experiencing this issue (both wifi toggling and battery issue) and know a fix? I've attached my battery graph from today.
Edit: It looks like the phone was "awake" all day today except for the time it turned off due to low battery. Also, it looks like Bluetooth is using way more battery than it should be.
Thanks!

So I found the culprit for the wifi. I have a tasker profile that turns it off when I'm not connected via Bluetooth to my house phone. This means that there is something wrong with my Bluetooth. Nothing has changed with my house phones. Any ideas on the Bluetooth?

Try getting rid of the Tasker profile. I don't think it's your phone. I bought Tasker and tried to set up some cool stuff but it kept messing things up. I don't use it any more. Android does a pretty good job of taking care of stuff without it.

Thanks that was actually the first thing I did when I found out it was a tasker problem. I don't keep wifi on all the time due to battery drain (unless I'm mistaken on that?) so I'll have to bring it back eventually. I didn't think android had a "turn wifi toggle on when home" ability.
I unpaired my house phones and I'm going to repair them tonight and see if that helps.

I've had this happen to me twice including just now hence why I searched for posts on this. Seems like it happens randomly when I stop using WiFi hotspot and I'm at home with my WiFi automatically trying to turn on. I use wifimatic which turns WiFi on when I'm near a cell tower near my home and shuts off when out of range of that tower. My WiFi won't automatically connect if I turn off my Hotspot, so I have to restart. Just twice now this drained my battery from like 30 to 0 in less than a minute. It's not often it happens and I'm home anyhow so putting it on the charger isn't a problem. Maybe this helps but maybe not.

It's been my experience that leaving wifi on doesn't drain the battery very much. I leave mine on. Besides, the quick toggle is very easy to use. Trying to automate it is more trouble.
