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....

Hi chasmodo,

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.

Sudden battery drop

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

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.

XXLS0 JB killing the battery. Anyone else?

Anyone else experiencing worse battery life going to official JB? My official ICS battery was much better. Much. I even did a hard/factory reset after I updated. Ive even disabled a lot of the "new" features like google now and multi view. Anyone have any tips? I used to last til 15% by 10pm on a single charge now im at 15% by 530pm... ugh. Any way to easily go back to Official 4.0.4 Germany?

When I check my Battery stats it looks like the screen is using everything. Im keeping it on the same settings I had on ICS. No auto and about 45% brightness standard.

I have the same feeling about the german jb official rom.
Screen is taking up almost all the battery. Any ideas to improve battery life? I usually do the recommended tasks such as no background process, low bright screen, few widgets and so on.

My wife's Note on LSO has been having terrible battery since the update. The drain is massive.
Too bad, she really likes the multi-view, but as-is, it's impossible to keep this ROM.

I have same situation- display uses more then any other rom in past...
What rom is best in bartery life- no matter GB, ICS or JB, probably custom with custom kernel. it is not important for me as batery life?
thanks

My phone idles alot and on lsa i noticed it loosing alot of charge just idleing
so much so i rolled back to 4.0.4
the final german release is just as good in my case for long idle times as it was on 4.0.4
cant say on long term screen use

I have same problem. After installing BetterBatteryStats
http://forum.xda-developers.com/showthread.php?t=1179809
I have discovered that AudioOut_2 wakelock is problem. After some investigation it seems problem is Skype or Viber. Currently i am in testing process. I will post any news here.
Update: after removing Viber, problem is solved :facepalm:

do try enable power saving...it limit your cpu max 1ghz only, thus could save a bit

@rames
I do not have viber and skype...

Whats the best way to rollback to 4.0.4? Thx

install CPU spy betterbatterystats and check for wakelocks.

I was getting 8 days of use out of LSA (I keep everything off GPS/WiFi/3G Data)
With LSZ I am getting around 5 days of use ... with the exact same usage ...
My CPU is almost always in Deep Sleep so I am starting to suspect the new baseband LSO (modem.bin)
P.S. Stock LSZ with PhilZ 4.63 Kernel+CWM ...

I had same thing so I simply did the following :
Enabled power saving then forced stopped every app which showed up in running services which was not needed and battery back to nomal now.
I found that maps and voice talk kept my device awake a bit so if you don't really use them daily then simply disable.
I seem to remember it was the same with stock ICS when first released then it got better so fingers crossed.

Guys why don't you follow ahalford's thread about battery life / wake locks? You'll find a link in my signature.

Only thing I really need in 4.1 is blocking mode.. I plan to back on rocket v12. Is there any with better battery life?

Having massive battery drain and unusual behaviour! Last night in 4 hours standby my battery went from full to 45%
Today as I used the phone it dropped from 40 to 11 and then went back up to 14%...

Notice how after the huge drop the battery actually goes UP!!!
I have installed GSAM Battery and Juice Defender and couldn't pinpoint the problem. I am going to try another factory reset and reinstall everything from scratch.

You have a lot of wake locks and apps.. These battery saver apps really don't help that much. Use betterbatterystats to find out what those are and check the wake lock thread in q&a sticky .

Galaxy Note GT N 7000
Try the Ultimate Jelly Bean ROM....it should answer your questions on battery drain. Check the forum for Ultimate Jelly Bean ROM

that's a problem of Germany JB, battery short life and can't use airview

Try LSF Trinidad and Tobago rom or Jonrom which is based on it. It has better battery life for me than german LSZ. Airview fix also working.

Battery eater JUST ON DATA USAGE

Hi
got big problem with battery life. But just when is on data usage. Not in plane mode and not on WiFi mode.
So last night set plane mode and go to sleep. Battery was on 42%. Woke up, turn off plane mod and turn on data usage. Battery was on 41% :good:
And did not touch phone screen in next 50 minutes. After 50 minutes turn on screen and battery was on 30%...then clean it with CleanMaster and HistoryEraser, reboot and battery was 20%?!?
So...in 1 hour with 2 minutes using 21% less
Once again...when is on WiFi there's no any kind of problem.
Did not said...just flash and ROOT stock BTU (british) unbranded ROM (from 24.10.2013. latest one) 5 days ago...and flash kernel for this ROM and flash recovery.
Found ROM and kernel on samsung-updates.com
I uninstalled many Samsung SW from phone and other SW i don't want to use.
Before BTU I had stock VIP (Croatia) and stock Taiwan ROM. And did not have problems with battery life.
Anybody can help?
Thank you

Check with Better Battery Stats app, and let me quess its RILJ that keeps your phone wake. No cure for that. Sometimes RILJ drains battery and sometimes dont, no matter what you do with your phone (somebody say its a Google location services blame for that, but I say its not, because I stopped it and still getting high RILJ wakelocks).

I'm sorry but when tried to install BBS it was so many malware there...so, when I will finished PC problems then will try BBS.
Thank you and I will post here when will instal BBS again.
EDIT:
Do I have to install BBS on computer? There is just .exe file...there's no .apk file i just can find .exe...and can't find .apk anywhere

I found BBS xda
And there's no any RILJ...when it's on Partial Wakelocks there's just BBS_WAKELOCK_WHILE_SAVING_REF and some other statistics but no RILJ
EDIT:
So..I found RILJ now but it's just started and it's 0,2%...will wait a while and then will post result

Question Sudden battery drain on cherishOS

Hello, this is my first post on xda so sorry for any mistakes.
I've had CherishOS 3.9.5 on sweet for a good while now and this problem started a month ago.
Device does not go into deep sleep at all, idle drain is so high that it doesn't even make sense.
For example today, when i went to sleep, i closed all apps and turned off the mobile network. There was a drain from 57% to 19% over 6 hours.

I rooted my phone and installed betterbatterystats for further investigation and found this
I found this today. Previously i scoured through forums for a similar issue and found that disabling double tap to wake should fix the issue. I did that and it did fix the battery, but only for 2 days and then it went back to the god awful drain. It's a real pain to have my phone charging all the time.
Any help is appreciated and I can post anything further if I missed anything here. Thank you

What Kernel u use? Had this issues too with different Kernel and Versions, but with AGHISNA-OSS-12-03-2023-signed seems all fine and working decent.
Give it a try, i wont touch my Kernel for a while, because never touch a running system.
Attached is the Aghisna OOS for LQ8000. If u have that other Chargingboard, u have to search on Sourceforge for it.

And kill the battery in the process. Another reason to avoid google.

calibrat your batterie try to using your phone until it turns off completely and wait 3 hours while it is turned off after that plug in without turn it on until you see 100% icon battery in the dark page and try to give it another 3 hours after that plug out and power on your phone and use it until 15% ..and voilà your batterie is fresh and calibrate and happy

Update to Cherish build 4.61 not newer nor older
this precise build specially the vanilla one with nikgapps core is very satisfieng combination with superb bb and barely noticable drain
try it and report back
ps: clean install is a must to have the best results
Good luck
