Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.
Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.
Yup i had it running too since boot.. cleared data and will report back
Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.
Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.
I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.
i lost 25% over night in airplane mode
background & sync = off.
after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h
Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.
Same problem here. I hate this device...
Is it just me that think battery life is much better than on froyo?

I have no battery drain since i upgraded to jvk.

I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places
I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

today the message is changed form "connection time out" to "no update available" maybe 2.3 is coming?
This worked for me.
Hiya,
Ever since I got my phone replacement (Brand New in Box from Bell) I noticed that the battery drains 10% per hour regardless of my current clock speeds.
I'm only listening my music.
My mobile data is on.
Wifi is off.
I have ES Task Manager set to autokill when screen off
Details:
ROM- CyanogenMod Nightly #140
CPU Clock speeds- 245~368 Mhz
CPU Governer- ON DEMAND
VM Heap Size- 48m

Just making sure I'm reading you right, you have es task manager killing apps? Android 2.2 doesn't have any need for that, and it may hurt your battery life.
First thing to check is to make sure any apps that sync (weather) aren't syncing every 15min, and change them to every few hours. If that still doesn't work, try a different battery. May just have a bad one.

Go into spare parts > battery history > partial wake usage
This will show apps that are running in the background that are using the battery. If there are any 'rogue' apps that aren't behaving properly, this should show it. You can also use Watchdog Lite from the Market (free) to monitor CPU usage of applications to try and find what is running down your battery.
Although, if you are listening to music, 10% drain per hour doesn't sound too much out of the ordinary.
Update: I stopped my music for roughly 45 minutes and it seems that music doesn't affect it much. It still drains.

Yea good call. And get rid of that task killer! No need for that, especially in CM7.
Having similar problems suddenly. I was getting nearly 24 hours of battery life with normal usage, but in the last 4-5 days the phone drains to death while in standby. Searched here and online and couldn't find anything other than the normal check apps, etc. But I haven't changed anything in months, and usage isn't showing anything out of the ordinary.
Is it possible my battery is hosed? Android OS says battery health is still "good", and outside of screen-off it seems to drain normally. I even left it on for about 30 minutes and lost 1%. But overnight it went from 100% to 1% in just short of 7 hours with absolutely no use. So bizarre...

It's not just you.
I have same problem, with two different batteries, even after hard reset.
I have been having this problem the last two days as well. The t-mobile forum says to roll back the updates to the google maps app. I just rolled it back, will see if it helps.

Didn't help me.
Only turning on airplane mode helped me.
I think it's a TMO infrastructure/network problem of some sort, honestly. Maybe a bug with the deployment of 2.3?
Yeah didn't help me either.
I had my phone fully charged when i made the post earlier and it is now dead.
Hopefully they shed some light on this soon.
OK good I'm not crazy
One thing I noticed last night after draining and wiping battery stats again is when I woke up it said Dialer took up 49% of the battery usage? I charged to full with the phone off, turned it on and it sat on the nightstand until this morning. Received 2 texts during that time, no phone calls made or received, and my alarm is set at 6am on it and went off. Battery went from 100% to 19% in this state.
This is frustrating. I read the T-Mo thread and it's seeming more like network issues? Anyone else have this problem here on XDA?
EDIT: Customer Support is useless. Insistent that forum posts "mean nothing" and I need to pay them $20 to replace the phone. Also they have no logged issues on this, even though I've seen multiple posts of people who've called in. Sigh.
Also been experiencing the exact same problem with CM13X and CM151. I had uninstalled maps, which didn't improve anything, so I reinstalled it and it appears to be okay now
So far 1h16m since full charge after uninstalling Maps completely and rebooting and clearing cache, and battery is still 100% while sitting on my desk here at work. Also Dialer isn't showing 50% usage either. Hmmm.
Hey guys. Recently my battery has been dying at an alarming rate. According to BBS it's from a process called diagnostics.client.Wakelock, does anyone have an idea what could be causing this?
I started noticing the drain after setting up my Galaxy Gear, don't know if that may have something to do with it.
Thanks!

Thanks! I'll give that a shot.
I am facing a huge battery drain as well after the recent update was pushed. I don't have the "diagnostics.client.Wakelock" in BBS but Samsung Push Service was hogging a lot so I turned that off. It was 80% at 11PM and today morning it was down to 59% .. that's 21% in standby mode. Is it not going into sleep mode or is something else causing this? I have almost everything turned off. Any ideas guys? Thank you.
MJ7? (not sure why but like other people remarked - the battery life looks to have somewhat declined - 30-60% less?)

Yes MJ7. I hope this is a bug that can get fixed sooner than later. It's horrible. I just got 1h 37mins of screen time and now I am down to 12%. Just a few calls and some Instagram. Nothing else. Would removing the battery for a while or something help? I haven't installed any app since updating to MJ7 (2 days ago).
I've had this issue with MI7 and MJ7 so the update is not the problem. My guess is me freezing most of the samsung bloat on the phone through Titanium is causing this. Maybe there's a process trying to find something thay I froze?
Sent from my SAMSUNG-SM-N900A using Tapatalk
I fixed it by charging my battery up to 90% then removed the battery and kept it aside for a while ~10 mins and then plugged it back in and charged it to 100%. Now it seems to be normal again. No drain last night. Moved only 1% from 12AM to 9PM. Cheers!
I have the same issue with MJ7 firmware; the phone sometimes doesn't get into deep sleep while the screen is off.
A possible cause of the issue: switch off wifi when data are off.
So now I switch data on before turning wifi off.
Anyone ever find a solution to this? It's killing me.
Same here, my battery declines almos 1% every 5 minutes just texting via Whatsapp and I know Whatsapp is not the guilty. Using Wakelock monitor shows 30% Android System usage with a lot of entries in Gpslocationprovider (even with GPS off and everything on Location settings off), SyncloopWakelock and AlarmManager... MJ7 here too... My Note2 wasn't like this... I finished the day with 5% of baterry after heavy use from 8am til 10pm (including 45' watching videos)... With my Note3 at mid-day I have my battery death!! I can't believe it! and I don't know what is happening (I only have 4 days with my new Note 3) and I have tried almost everything (deactivating) except wipe data/factory reset (I've tried soft reset and nothing)
Anyone ever find a solution to this wakelock?

Delete Google search from system apps and deleted Google play services. Redownload both from play store. Seems to help.

I noted that my GN3 would have great and then poor battery drainage. It seemed to happen right after my first long call of the day. I noted in my wakelock app that diagnostics.client.wakelock was using a lot of time.
I decided to take more drastic action by doing a factory reset and restoring apps one by one. I first used Kingo Root to root my GN3. I had to uninstall Kies and the Samsung driver to get the rooting to work.
Then I backed up with Helium and Titanium backup.
After a factory reset, my battery usage was about 0.2 percent per hour. I use only data and no wifi.
I have now restored most of my apps and still have 0.3 percent per hour usage. I have not updated any Samsung or ATT apps.except for ATT code scanner. i have not "used" any of the google apps except for gmail, search, google+ (signed out). Google music is turned off.
Diagnostics.client.wakelock still shows up but with low time now.
After twelve hours, the GN3 is at 96 percent including a two minute phone call and email updates.
------
After a long phone call, I once again saw my battery usage increase and stay up after the phone call.
-----
I re-started with a factory reset and only restored the minimum apps that I use to browse, email, text, phone, and backup.
So far it is performing well in battery usage.
I will be adding more apps until I find the one that breaks the good performance.
-----
So far I have been able to make it through 24 hours using only TEN percent battery usage. I have added TextPlus, BofA, drippler, Helium, Titanium Backup Pro, CPU Spy Plus, Wakelock Detector, System Tuner Pro, Battery Monitor Pro, AutoBluetooth, Maps, Youtube, YP, Total Commander, Visual Voicemail, Quick Boot, Root Checker, Turn Off Screen. Everything else is stock without updating AT&T apps or Samsung apps.
I am seeing an idle usage of less than 0.3% and that is with two widgets for Battery Monitor and System Tuner. They and Textplus use up the most power. I also talked on the phone via bluetooth for about 30 minutes.
I still get the diagnostic.client.wakelog but only getting about 5 percent awake time.
-----
I did another factory reset. This time I did not allow any app updates.
I installed Titanium Backup, CPU Spy Plus, Wakelock Detector, Battery Monitor Widget Pro.
I have not seen a diagnostic.client.wakelock at all after one hour of use.
-----
I added TextPlus, System Tuner Pro. I put the widgets to System Tuner pro and Battery Monitor on the home screen.
I have not updated any apps since the reset.
I have counted about 7 diagnostic.client.wakelocks for a total of 4 seconds of wake time. My wake time percentage since yeaterday is around 1 percent.
I plan to update apps one at a time to see which one kills the battery usage with wake locks.
I just added AT&T Visual Voicemail, PayPal, BofA, and Evernote to my GN3.
The diagnostics.client.wakelock started climbing and keeping my phone from sleeping.
Uninstalling the four apps did not help.
I think that the problem is with the Visual Voicemail.
----
Factory reset my phone and am back to 1 percent wake state and very low battery drain.
----
The cause of the bad wakelock was due to restoring APP+DATA in Titanium Backup. I did that to save setup steps.
I had restored BofA and Shazam with data and the wakelocks started up.
After I factory reset again, I installed apps the normal way and have been seeing a 0.3 percent use per hour.
Samsung's own software is most garbage in my opinion.
If you use ChatOn and Samsung Hub, etc, disabling this may have an impact.
Here's how I've solved the problem with this pig of an app.
1) go to application manager under settings.
2) go to the "ALL" tab
3) find that "samsung push service"
4) uninstall - this will only uninstall the updates. Once all the very useful updates are gone, the option changes to disable.
5) disable and good riddance.
On a side note, search for this on the playstore. the reviews are hilarious.
c.
Nothing I had tried up to today has fixed my battery drain and diagnostics.client.wakelock issue.
However, today, I got a software update OTA (nb4) on my phone and it appears the problem is fixed.
Has anyone had issues with really bad battery drain on newest update?

Bad Battery Life
Hi
Yes, I have noticed a dramatic drop in battery life. I use to get home from work about 6pm with about 50% battery life. Now by 2pm I'm less than 10%.
No Bluetooth. No GPS. No NFC (this was originally on when getting to 6pm). WiFi on. WiFi Off. Doesn't matter. Turned location services to battery save or off. No new apps.
I have converted runtime to ART (worth having a read up on this), which can potentially give up to 20-30% better battery.
The funny thing is at home with full WiFi and strong 3G reception the battery life is exceptional! 2-3 days standby (light/medium use). The 3G reception at work.
A friend suggested that possibly the radio (3G) isn't locking on to a specific tower and keeps bouncing between towers chewing up the battery.
I will try a factory reset and see if it fixes the problem. From what I've been able to discover online it doesn't seem to be a very common problem.
Same Here
My girlfriend is having the same problem with battery drain.
GPS is off and she's using Wi-Fi at home.
When Google rolled Kit Kat OTAs I had to wipe her phone and flash the official Mako factory images to actually get it updated. So the phone isn't rooted and It's completely stock now. The 4.4.2 OTA update installed just fine. Then she noticed the poor battery life. Android system and Android OS are the 2 highest battery users in the list (will try to get a screenshot of this later)
Is the factory reset working for any one?
Has a reinstall of the factory images fixed this?
Any other suggestions?
Just wanted to ask everyone before I spent a bunch of time on it.
Thanks so much!
factory reset doesn't resolve
I did a factory reset and the issue still exists. I have removed 1/3 of my apps, 80% of the photos on my phone. I tried running Bluetooth off 100% of the time. Turned off location reporting. Turned off syncing any Google service I wan't using. None of these helped. My problem is intermittent. I will make a change then go a couple of days thinking "problem solved," then on the third day massive battery drain reoccurs. I think the battery monitor in the OS is unreliable when this occurs becasue it will report an app like "Flixter" as the main source of the drain. The next time it will be mediaserver, or TV Guide.

I have read millions of forums and this problem is not going away. I also have intermittent battery drain - it works for a few days and then everything goes back to sh-it. I've tried everything - deleting apps, turning off all services i don't use, power saving mode, sync, GPS, and nothing works.

Thanks for that note! I know my gf uses the weather channel app. Will tell her to remove it.
On a similar note. Now a few months later now and her battery wont hold a charge for more than 2 hours and wont charge to 100% every time. Her phone is only a year old. luckily she called google 2 days before the 1 year warranty was up. They sent instructions on safe mode and some other tips. Hopefully she'll end up with a new battery and i'll make sure shes not using weather channel haha.
Hi there, for the last week or so, with no new apps being downloaded prior to issue, I have noticed a significant battery drain by Android OS (39%) and inside it showed incredible Keep awake time of 16h 50m (though the phone screen is off). For reference, the screen time (25% battery usage) so far is 1h 31m. I have installed and given root access to GSam Battery Monitor (its root companion is activated too). The program indicates that Kernal (Android OS) is taking up my space but I was hoping instead it would be able to give the direct app that is eating up my battery. I have tried restarting it twice and after letting the battery run off completely and fully charging it before turning it back on.... no dice.
S4 - SGH-i337M (jfltecan/jflte)... verified root... Android 4.4.2
SlimROM-4.4.2.build.4-OFFICIAL-3650
Build number: slim_jfltecan-userdebug 4.4.2 KVT49L 3650 test-keys
Kernal: 3.4.82-KT-SGS4-gb0a91ad
Recovery is via TWRP
I know there may be suggestions to turn off GPS, WiFi, etc, etc... but I'd rather not do that due to the fact the phone life was absolutely fine w/ them on... I'd like to fix the root of the problem instead of working around it. I haven't made any changes to phone settings for a month. Reformat is a last resort but want to exhaust options prior to.
Any help appreciated, thanks.
It seems that the only way to have figured it out is by disabling individual apps and see if there is any improvement in battery life and drop in Android OS wake time and battery use.... After checking the 4th app of possibility, it seems like KiK was the culprit. Just going to remove the app as I haven't used it much. Maybe an update for the app occurred causing this to happen. One work around for those who want to keep the app that's causing the issue and minimize the battery drain, you could just go to the app's system settings and do a Force Stop and the program will be off and then turn the app back on whenever you need it and then turn it off again via Force Stop. It's a app issue, not anything you can really do about it except downgrade or uninstall the app.
