Sometimes I get this issue, and I can tell within the first 3% of my phone's battery dropping. The first thing I do is a battery pull, that fixes it.
if that doesn't work it must be a setting or an application.
EDIT: from your usage, it seems that your phone isn't going to sleep. Try an app called Badass Battery Monitor from the market. It will show what apps are using your battery life. link here: Badass battery monitor
Try deleting some recently installed apps.

I had the same problem. First couple of days I got way more than a day and after that it got like my two year old Droid; It sucked.
Turned out that K9 was a battery hog and drained the battery for about 30 percent. Threw it out (though you can also do some adjustments to it) and got my old battery life back. Have a look at the stats to see what is taking up your battery and try to find a solution.
There's something preventing your phone from going to deep sleep. Take a look at 'Awake' and 'Screen On' lines at the bottom of your screenshot:
The right hand side of those two lines are as it should be - the phone is awake when the screen is on.
But the left hand side is wrong - your phone is awake with no screen on (meaning no user activity). Could be a rogue app running in the background and consuming battery juice. Why don't you investigate what you have installed in the past couple of weeks and see if some app is misbehaving.
Also, your WiFi is constantly on (look at the continuous fat line at the bottom). You'd do well to switch it off when not needed, or set WiFi sleeping policy in Settings/Wireless and Network/Wi-Fi Settings/(hit Menu button once inside)Advanced/Wi-Fi sleep policy.
Hope this helps.
I had exact same problem. I tested by removing recently installed apps until I found the culprit. Turned out to be Google+ in my case. Once removed battery was back to normal.
Some more tips on prolonging your battery life:
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Don't let your accounts sync automatically
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
Folks I followed some of these tips and this its the battery life I an getting on checkrom v5. Better than my old captivate....

I can't see a good reason for disabling autobrightness... in my opinion this option saves more power (in the long run indeed!) than its backgroundprocess will cost.

Dear All,
here is my Note 2.3.6 stock rom with Franco #6 kernel Battery usage (in pic 1&2)
It shows that my note was awake mostly all the time although as you can see from the pic that the phone screen is off most of the time (almost did not use it that day)

1-is this because I was leaving the wifi on most the time?
Edit: I turned the wifi before sleep and after 6 hours I found the phone was awake all the 6 hours and sygic was off
this an old pic (couple of days before) and you can see my wifi was on all the time while the phone was not awake most of the time
2- Why my signal bar in pic is yellow and not green as usual?
and in pic 2 here is my apps, so which one caused this awake?
Final results after long day of asking, getting help from replies here, reading and trying, everything is fixed after doing restart

Don't keep your WiFi and GPS (Sygic) on all the time. Looks like that's what's stopping your Note from going to sleep.
Don't know if this is an actual fix, but what I discovered is that turning the screen off by pressing the 'Power' button on the side helps tremendously in preserving my battery life. If I just let the screen time out, my battery gets drained big time.
This may/may not work for you, but it's worth a shot...
(EDIT: This still holds true even when I keep my wi-fi on)

Well both old and recent screenshots show the same battery drain and quite similar usage, they lasted for a day and a couple hours.. I think it's a glitch in the system info.
Had a problem a week ago with heavy battery drain in a quite similar manner and I can guarantee that if the phone didn't entered sleep mode it wouldn't even last those 24hrs.

do you mean that the phone entered deep sleep but the results are not correct or not true?
I have also CPU Spy and it shows that my phone did not enter deep sleep during the last 30 hours (or more)
try uninstalling Sygic.
---------- Post added at 11:29 PM ---------- Previous post was at 11:26 PM ----------
Also, Voice talk has the option to be ready all the time, by "Hi galaxy" command, try disabling that.
Does anyone have an idea as to what happened to my battery here? I'm thinking faulty battery unless someone has seen this before?

Does this happen often???
Cuz im facing the similar problem but for me .....gigantic battery drops occur after i resart the phone.......may be we should change our KERNEL. I heard hydracore is gr8
I wouldnt say its your battery, If you look at the blue lines below you will see that there is a big gap when screen is off, Yet the phone is waking up many many times whilst the screen is off.
This says to me that there is an app causing your phone to not enter deep sleep. Your best bet would be to install Better Battery Stats (free on XDA, Paid on Play store) and/or Watchdog lite.
this will tell you which apps and proccesses are using more power than needed. Then you can take action from there.
Battery drain is an issue for most android users, and has millions of possible causes, so elimination is key to finding the culprit.
ofcourse.. this is happening because of wakelocks... power off the phone. remove the battery for a minute and pack it up again boot into recovery.. wipe battery stats and check again

It's only happened this once. And I think the vertical line suggests it was during a reboot?
I've dealt with wakelocks before but never seen this. I'll have a look with betterbatterystats to see for those wake events.

I'll give this a go.
This occured to me on XXLSA Jelly bean, after researching, I found it is due to media scanner running for long time
I used Rescan media root app from play store to disable media scanner and this didn't happen again
It is worth noting that this problem would NEVER happen in CM-based ROMs - Huge battery life!
Hmm I've been running CM10 since the nightlies first appeared and tbh, whether on original battery or gold battery or my extended battery, I always get drops offs (maybe only 5 per cent) on any reboot
Sent from my GT-N7000 using xda app-developers app
I noticed battery drop after I started bluetooth my music through my car stereo.
Apparently it's a bug in a file called "media server" in Android that causes that.
The short fix is, after I stream music, if I'm not going to stream for a while, I reboot
the phone. Killing the service for media server won't stop it, you have to reboot.
I ran a battery program that showed overnight, the media server wasn't going to
sleep, kept wakelocking. After rebooting, the battery only lost 2-3% overnight,
and before, it was losing 10-20% overnight. Might be worth looking into.
full decharge (1bar,not really full) and fullbrechargr cycles might make it better. A sudden drop like this screams battery replacement. If in warrantee period get it replaced.

Okay, first of all, I'm on an Xperia V, with latest firmware (4.1), unrooted.
So lately I've been having trouble with battery life. I don't really use my phone much, since I've got a Nexus 7, but the phone just plows through the battery.
The problem was that the phone always stayed active, even with battery saving modes on. Now I didn't use many sensors, like GPS, NFC, BT, and WiFi Location, but still I couldn't get it to last very long.
Now two days ago, I factory reset it and set it up. I tried Smart Connect and Location Based WiFi to automate my phone, and battery life was pretty good, definitely better than previous.
But now today, my battery life is once again bad. I haven't really found the source of the problem, it's not an installed app that drains the battery, and the battery usage shows that 'Media' and 'Android System' drains the most battery, and that the phone stays active when it's sleeping.
I've also noticed that my signal drops frequently, even though I'm in the town.
What can I do?
TLDR; Xperia V, latest 4.1 firmware, unrooted. 'Media' and 'Android System' drain most battery, phone stays active all the time, no GPS, Location, NFC, BT. Tried factory reset. Don't know what to do. Frequent signal drops too.
I'm gonna try a factory reset without the SD-card, I don't even use it.
Here are battery and wakelock screenshots:

Err, that is normal use.
Your phone is in deep sleep for 49% off the time, that is normal. You have 38% battery after 21 hours use, that is good.
If you keep factory resetting then every time you boot it has to use media scanner again to rebuild its data bases..
My suggestion I'd to leave it for a few days to settle down, then see how it is

No, it can't be.
Android System and Google Services shouldn't drain 70% of the battery, neither should it keep the phone active 75% of the time, with less than two hours of screen on time. My Nexus 7 has been 'active' 20 minutes, with 5h of screen time and music playback.
I had the problem before, that's why I reset the phone, and now I have it again. I don't think it'll settle down.
You can always ignore my advice if you want.
But your own images show 49% deep sleep and 33% battery left after more than 20 hours use. Trust me this is good and normal, and most users here would bite their right arm off for that
Also, if you keep resetting you are going to drain the battery quicker.
But like I said, you are more than free to ignore this advice and keep resetting your phone.

I'm not ignoring your advice, I'm not resetting, I'm just trying to find an explanation and a solution. Thank you for your answer.
I think I have an issue with my battery, or possibly phone!
On my Galaxy S3 LTE I've been experiencing very poor battery life recently and have tried a few suggestions to improve it.
I have kept the screen brightness on -5, I have applied Power Saving Mode, disabled 4G mode (not using currently anyway) and installed a battery saver app (Internet Commander). However none of these seems to have made a difference!
As an example, here is my phone at 5.36 this morning on 71%. That is after I took it off a full charge at 11.30pm when I went to bed. So in Standby it had used 29% in around 6 hours. Then it just got worse through the day...

At 3.23 I had just 8% battery left!! And that was after a top up charge of about 20% around 11am!! I had listened to half a dozen songs on the phone but thats it!
As you can see I do have data enabled, and just the standard apps installed (WhatsApp, KIK messenger, facebook, BBC Weather, Sky News, etc...). I also only have 1 widget on my home screens which is the BBC Weather app widget.
Could it just be a faulty battery? Would a faulty battery cause this kind of rapid decrease?

I blame those battery intensive apps showing in your statusbar. Your battery is being used by Cell Standby, this is your Data connection being used to receive notifications. The fact that you have high Google Services percentages also points to this since it uses your wifi and radio to get your location periodically when set to do so. Start by disabling feature under location settings. Next, have a look at Android Device Manager in Google Settings, disable the location setting if you do not intend to use it. Anything that uses your Data, will cause more drain, especially on higher bands like HSPA.
Again, Whatsapp and Kik will constantly receive push notifications and sync, this also adds to your battery drain.
Thank you, I will try your suggestions
Hi, i had the Problem with huge batterx drain too. The battery didn't last much longer than 8 hours. My phone didn't go to deep sleep mode
I then installed wake lock detector and One Power Guard. In One Power Guard i aktivatet AI mode and now it looks like this:

Hello guys,
Can you post some details about your average screen off consumption ?
And some details about the variant/conditions like : Exynos/Snapdragon, 12GB/16GB, 5G/4G, mobile data, wifi, Bluetooth on, dual/single-sim use, AOD on etc.
You can use Accubattery or similar app to test it.
I am at 34.3mah/hour.
Exynos, 12GB, 4G, mobile data, wifi, Bluetooth on, dual-sim, aod off
Edit: i think the ROM Will also be relevant. I am on AUB9
0.4%/h with AUB6. before AUB6 was 0.7-0.8%/h
512 exynos, wifi/4g, aod on tap, bluetooth when needed, AUB 9

Sorry 0.1% per hour screen off drain time seems almost implausible
I get like 0.6/0.7% per hour screen off drain overnight on WiFi and most things turned off (don't need nfc, Bluetooth, location etc. whilst I'm sleeping). Goes up if I'm using the phone
Did you see an instant improvement removing those apps or was it gradual? Did you deep sleep apps yourself or let the system do it?

Can't hurt to try, quite liked the notification bar refresh rate notification but can live without. My battery life is reasonable but can always be improved

It is hard to believe, but it is very clear. Are you on Exynos or snapdragon? I use maxHZ, but it is optimised and I don't see it to be on consumption list.

So I deleted both naptime and Galaxy Hz (it's worth noting the latter doesn't need to be unoptimized in settings).
Looked like Accubattery is buggy on my phone (S21U Exynos) as it claimed I lost 0% in 8 hours of screen off, but 5% in the 10 seconds of SOT I had. (Stupidly deleted the app without screenshotting)
GSAM as shown below shows it was actually 5% in just over 8 hours but appears that my Naptime behaviour was still implemented despite removing the app (forcing doze without motion sensors makes it stay in light doze with all the characteristics of deep doze).
So from my brief one night study, no discernible difference having Galaxy hz installed and optimised vs uninstalled. Am reinstalling Naptime to try and get it to turn off and see what happens tonight.

Nice just made a routine to switch to 2G and turn off mobile data when at home and connected to wifi, this should increase battery even more
Galaxy Labs has battery optimizing modules. One of them tells you which apps sip what amount of battery.
