Battery life after update--battery stats have been reset? - Vibrant General

I was noticing people complain about bad battery drain after the update, and it occurred to me that the update may have wiped the battstats file. My phone is definitely off-- I just popped in a fresh battery this morning and it stayed on 100% for 4 hours, so my phone definitely needs to be recalibrated.

EDIT: nvm found it
1.) Drain your battery to the point it shuts off on it's own..
2.) Plug it in & let it charge over night (While it is still off)
3.) Launch into ClockWork Recovery by holding the "VOL UP", "VOL DOWN", & "Power" release those buttons after you see the second Vibrant screen.
4.) Press "reinstall packages" (It should take you to the Clockwork Mod Recovery screen, If it didn't then press "reinstall packages' again)
5.) Go to "advanced"
6.) Press "Wipe Battery Stats"
7.) Reboot

I know i've seen discussion on xda forums or another about the battery life being demolished after the update. My battery life went from decent pre update to horrible post update. Anyone?

I think mine got a little better. I think my batt indicator in the nitification bar seems worse. I'm at 80% now and it shows I'm 100% full.

i dunno. i went to bed last night with my battery life at like 40% and woke up to it turned off. never happened since i've had the phone until now.

HORRIBLE battery life after OTA
Before the OTA update, I could go a full 2 days of MODERATE use without charging.
Now, after the OTA, I don't even get ONE full day of LIGHT use before I need to recharge! W T F.... WWW TTT FFF ???? !!!!!!!!!
WTF good is a working gps, if my phone is always dead when I go to use it???
OMGWTFBBQ I wish there was a smiley to express my EXTREME **RAGE** at Samsung.... aaaaaAAARRRRGHHHHHHH

Judging from my current battery life draining the battery until it shuts off on its own is a few hour wait . Its pretty sad now since it goes from about 91% to 87% in just a few hours of just sitting there. I've turned off twitter or facebook updates or severely curtailed them to every 6 hours and did a bunch of other juice saving ideas. I just bought a new battery as well. its the 1600 mah one on ebay. Pretty soon I'll be weighted down with extra batteries all the time if this continues. Kinda lessens the whole "smart" phone idea if you cannot run any of the stuff that makes the phone smart.

This issue (bad battery life after JI6 update) has been resolved. Samsung Epic users discovered it and figured it out, and it has been slow to make the rounds among Vibrant users
Thread here - http://ip208-100-42-21.static.xda-developers.com/showthread.php?p=8675924
The problem is that the JI6 update installs 3 new services that run resident on the phone and eat up your battery.
Go to: Settings | Applications | Running Services
Two DRM services and a downloader services (i forget the names) should be killed. This will restore your battery performance back to normal.
Unfortunately, unless you root and remove these services.... you will have to turn them off manually every time you power the phone back on

I see a single DRM and downloader only
Can you speculate on the DRM services you are talking about?

Yeah I deleted the drm and media hub through Titanium. Basically, the dem service is buggy and polls too often, not letting your phone actually sleep.

Anyone tested this? I am still running JDF so i cant test it out. Hopefully this is the fix. The battery drain is the only thing keep me from updating to JI6

Which exact drm things need to be deleted? I deleted both the drm storage and already got rid of media hub as soon as I updated. A little more info besides "delete those drm things" would benefit the community.
Be very specific.

I can't remember the specific files, but they were identified in that Epic thread. Here's a way to check: Go to Settings> Applications > Running Services. If you see a "OmaDRM...." service going, it's still there. If it's not running after a bootup, you're good to go.

The JI6 will still be a bigger battery drain because the radio uses more power under this ROM. It's great if you have reception issues where you live, but definitely hits the battery. What you can do is update to JI6 and then just flash the JI2 or stock radio. That way you get the JI6 benefits (GPS, reduced lag) while keeping around the same battery life.

Sprint Update Ruined my Epic! - No 4G!

I've been trying hard to avoid the Epic update, since my phone was working great. I was getting almost 20 hours battery before being asked to charge, using about 30 minutes phone calls, 1 hour "display on" time, bluetooth/wifi off, GPS only when needed.
The nagging update available message would always pop up, and I'd always tell it to install later.
Somehow, I must have accidentally selected update while getting out of the car today, since I saw the phone installing firmware and then reboot.
After the reboot, my Sprint Hotspot stopped working. Now when I activate it, it turns my 3G radio off. Prior to this, I could activate (and use) Sprint Wifi tethering even though I am not specifically subscribed to it. Now, it still "activates" but shuts down my data connection.
Even worse, when I try to activate 4G, it just hangs the phone. I tried factory resetting, which did not solve the problem. Still no more 4G. Also, I noticed my battery getting really hot, and the smell of smoke inside the case. The battery went from 50% to 9% within a minute!! I don't have any explanation on how the update caused this.....
This update fried my phone! I'm going to try the Odin method back to DG27. If that doesn't work, the phone is going back!
DO NOT UPDATE if you can avoid it!!
that sucks
I'm having a really really hard time believing the ota update had anything to do with anything you described.

Me too, but I don't know what else could have caused it. Just tried Odin, still can't get 4G to work.
I don't think there's much else I can try. The phone just hangs when I enable 4G. Tried factory reset, Odin back to DG27. No luck.
Any ideas?
Dont listen to this guy -- you want the DI07 update on your phone. It has vital improvements to the radio and kernel. It doesn't break 4G or ruin battery life.
it has happened to many of us,including me..i also started a thread in the development forum..i talked to a service rep and they instructed me to do a msl reset,which required a msl code the give and no luck..this happened to me last week.since then i swapped my phone for another unit an was weary of updaing again,but i did and everything works fine now.im guessing a bad batch of phones or bad dowload/install of update ota.return it for another
Sent from my SPH-D700 using XDA App
Before the update, I was getting about 14-15 hours of battery with my average daily use. After the update I'm swapping batteries every 6 or 7 hours. I started tracking power consumption a few days ago with Spare Parts. I flashed back to stock with odin, and installed the DI07 update. The only apps I installed were Battery Indicator Pro and Spare Parts. I noticed right away that the running time was always close to 100%. That means that the phone is not sleeping. Under "Partial Wake usage", Android System is running almost the same amount of time the phone is powered on. It's not spiking the CPU, but running just enough to create a partial wakelock. This behavior is consistent on every boot. Normally, Android System should only keep the system awake about 3 or 4 minutes per hour of uptime at most. I think they botched something in the update.
Tonight I reverted back to DG27 and the problem is now non-existent. I only have one Epic to test, so I'm curious to see if anyone else gets different results. If it's just my Epic, then I will be returning it for another.
Anyone feel like experimenting?
I'm going on 18 hours now since I reverted back to DG27 and I'm still on the same battery. I would be on my third battery right now if I was still running DI07. I don't think I'm gonna be updating till Sprint releases another fix. Other than Media Hub and the loss of battery life, I noticed no changes while running DI07.

I'm getting over 18hrs since update. It maybe just like the HTC phone when you flash the rom the battery life goes down for the first few full charges then after that it's fine. Maybe I'm just lucky because I'm not having all the drama you guys and others are having.

Any why should we listen to you? Can you describe your source of knowing how this update has "vital improvements" to the radio and kernal? What are the nature of these improvements?
Thanks
-Everyone
Not sure what the particular improvements are... but check your phone info and you will see that the baseband was changed, which means a new radio was implemented. Also, in the release notes it specified that there were some "Qualcomm Updates", and since Qualcomm engineers the radio in our phones, it doesn't take much brain capacity to put 2 and 2 together.
I've updated and have experienced none of these problems. (As I suspect is true of most of the people here.)

It ABSOLUTELY ruins battery life. If it doesn't ruin your battery life specifically, then your one lucky sun of gun. It cut my battery life in half. I used to be able to go to 11pm and never even get a battery warning! Now, my phone completely shuts down by late afternoon while I'm still at work. DI07 is a horrible update. I don't know what Samsung/Sprint did, but my screen is dimmer, battery life took a major dump, and the phone does not seem any faster, actually slower if anything. My phone also seems to be hot all the time, even after it's supposedly been asleep for hours. With DG27 it was always felt cool when pulling it out of my holster and not hot like it is now.
Testing...testing
After running DG27 for almost 24 hours with great results, I decided to give the DI07 update another shot. But first I made a Nandroid backup in CWM before I accepted the update. After about two hours on DI07, it was clear the phone was not sleeping again when the screen was off.
So now I'm gonna try another experiment. I've done a system restore from my Nandroid backup to DG27. Except that the Baseband(radio) is still DI07 because Nandroid doesn't touch the radio. I'm thinking that this will tell us if the new radio is the culprit, or if they just botched something in the DI07 ROM.
Dev's, let me know if I'm off base here. I will report as soon as I have any relevant results.

Heres what will help:
Run the root script, delete all sprint bloatware, and keep track of all the services running on your phone. I'm getting 20 hours of battery with heavy usage on the DI07 update.
Also, try the bump charging method which has helped me a lot. Turn the phone on, let it fully charge, unplug, let it fully charge, turn back on.. rinse and repeat. It helps.
The update is not what is causing bad battery life. The screen dimming is part of the auto-brightness setting and/or power saving setting which should be helping the battery more than killing it.
Get System Panel/spare parts or any kind of task manager to MONITOR (not kill) processes running on your phone.
Here's a post from another forum, so I'm not the only person with a dead 4G radio. I believe it was temporally related to the update, but reverting back to DG27 didn't fix it.
Link: http://forum.androidcentral.com/sprint-epic-4g/36985-4g-doesnt-work-after-di07-update.html
"I have been out of town in a non-4G area since applying the DI07 update. Got home earlier today and just went to turn on 4G and it no longer is working!!
When I enable 4G (through the pull-down or the settings menu) now it just says "On..." and then "Unknown..."
Anyone else that has applied the update and lives in a 4G area seeing similar behavior?? I am currently backing up me SMS messages so I can do a hard-reset to see if that will fix it."

Infamous,
These are all good suggestions for basic power management under normal circumstances, but for some reason this update has introduced an issue that causes the Android System process to prevent the phone from sleeping. Why it's not affecting everyone I don't know. Some people had to take their phones back to the Sprint store after the update because they got so hot and would not cool down unless turned off.
Anyway, if you are getting 20 hours on heavy use, you obviously don't have the bug. But to anyone who thinks they might, you can check using Spare Parts.
First, if you've just rebooted, turn the screen off and let it sit for a few minuets. Open Spare Parts and click Battery history. By default it displays 'Other usage'. If your 'Running' percentage is 100% or close to it, and your 'Screen on' percentage is anything other than your 'Running' percentage, then your phone is not sleeping when the screen is off.
Next change the top tab from 'Other usage' to 'Partial wake usage'. This will show you what is preventing it from sleeping. You can click on whatever is at the top of the list to see its partial wake time. If it's 'Android System', the partial wake time should not be any more than about 1 minute per hour of system uptime. For example, if your phone has only been on for 10 minuets, and 'Android System' has a partial wake time of 2 minutes, you have a problem.
Found more info here.
http://forum.androidcentral.com/sprint-epic-4g/37034-those-batt-issues-after-upgrade.html
This is great info, according to Spare Parts and your info, I have a severe problem. I have just killed DRM
The update went through automatically Sat night, battery has dived at least
50%. Reboot at that time.
Battery History
Total in all Time Since Reboot (2 days)
Running 30.5% 99.7
Screen On 16.7 18.3
I see the problem, don't know if DRM dead will fix, is there anything else I can do?
I am rooted (or at least I was, I stayed stock and added Wireless Tether, it is broken). So not happy there either.
I will charge and check this tomorrow to see what changes or if there are any other suggestions.
Thetwo apps running none stop are I! Agent Service in Android System and GTalkService in Goggle, using over 10 mb ram
Other usage is still almost 100%, Screen time has gone down, but Wifi On is same as Running and I have it turned off every which way I can find as with nothing showing on top bar.
Partial Wakelock: Andoid System is on 113 hrs of25 since boot.

extreme battery problems

So I have been having some battery life issues like some users not being able to get a full day. But there has been a few times I have had my battery at %50 and then after a reboot it starts up and says plug in charger your battery is dead. Today I had 90% only been using for a few hours. All I did today was remove handcent and put on go sms. I also installed juice defender but I have it just on default settings. Go sms was stuck in a search so I rebooted my phone. I had 90% battery and when i started back up it says my battery needs to be charged. I have done the whole charge / whipe battery thing before didnt seem to help.
Oh and i'm running dk28 mightnight rom.
sounds like a bad battery. Most sprint stores with service centers have a cadex machine that they can test your battery with.
I have been seeing the exact same thing. I will reboot the phone with what appears to be a lot of battery life left and when it comes back I'll get told I'm at something like 10% and I should connect the charger. Luckily I have two batteries and I keep the second one with me in the pocket case/charger.

Same issue here with drastic change in charge level after flashing a ROM or even just flashing a new app or UI change via CWM when using my cheap ass Chinese eBay batteries. I've yet to be able to recreate the problem while using my stock battery - and I've tried. If you are using the stock battery, it's probably going bad. If you're using a cheap eBay battery, well, you get what you pay for I guess.

Both of my batteries are stock and I don't think it's a bad battery. I can go several days with great battery life from both batteries and then out of the blue I'll restart the phone for whatever reason and POW! Come to think of it the only reason why I usually restart the phone is to either swap batteries or because performance has dropped dramatically. Now I am wondering if there is a run away process that is chewing up the battery but the usage isn't being reported until after the reboot.

My battery is stock also. And mine appears to be random also sometimes I will have mild to high battery drain and other times its BAM %50 to 0 on a reboot or something it doesn't really match up with use or anything. I do have a Chinese battery on the way. I'm draining the battery down a bit more now and going to do another full charge with it off and then wipe the stats. Hopefully it helps will also try to stop at the sprint store and have them test the battery.

This was most prevalent for me when running EXT4 using the ext4 compatible bonsai roms (and the other ROMs that use bonsai as a base)
i've gone back to RFS and the 1.0.4 (I think) bonsai ROM and the problem has gone away.
my phone would be fine for quite a while, then i'd notice crappy performance, browsing, texts not being sent/received so i'd reboot the phone and come back after boot and the battery would be almost dead.

I am on ext4 also. I have been thinking of going to another rom and possibly off ext4 but I was trying to wait for final froyo custom roms..ya I know stupid me lol
I'm ruining running "stock" DK28 so I don't think it is an EXT4 issue as much as maybe an issue with DK28.

Looks like it goes away
I am currently on Bonsai v2.0.0 rom with Gingerbread Theme.
My battery performed weird when I just flashed to Bonsai rom. After reboot, the battery suddenly dropped from 50% to 15% and told me to charge. However I believe it happened due to flashing a new rom and battery not calibrated.
However, after a week of normal using, the battery seemed to have been calibrated itself. Now it performs okay. I have been lightly used (facebook, XDA, Engadget, weather checking on Wifi) with screen brightness set to auto. I also played music on phone speaker for about 20 minutes while I am cooking. Oh, I didn't get a call, so no call usage. But I did some email checking.
I had Advanced Task Killer set up to auto kill processes every one hour. I killed facebook when not in use, as I heard that facebook chat causes major battery drainage. And I also set mostly black wallpaper in hope to save some battery. I heard that saves battery a lot for some reason.
Anyways I have attached the screenshot, although I didn't use much, I believe that I can withstand a day with no problem.

Not to change the subject but you brought up Swype. Is it just me or has anyone else noticed that the more they use Swype the worse it seems to get? I loved it at first but now it seems like it's been hitting the crack pipe.
With due respect I think you're all wrong. I've had the same issues... sometimes at random after a restart
Shut down
Pull the battery
Put it back in
You should see your normal battery life
It's actually reading way lower than the battery actually is

Swype remembers mistakes that we make when hitting each key.. once a week or once every couple weeks I'll go to menu > settings > spplications > manage > select all apps > swype > force stop then clear cache.

The thing is, it shouldn't be happening. I can say for certain that after removing EXT4 and flashing back to the last stable (for me) Bonsai ROM I have not encountered this anomaly even one time (been 2 wks so far)... call it a coincidence, call it a solution. You decide.
Just sayin'

I tried this and no luck. I restarted the phone with about 80% and when it came up I got the critically low attach charger message. I then powered down, removed the battery, let it set for a minute, put the battery back in and booted. Still the same message. I'm keeping better track of usage and such today to see if there is something I can contribute this to.

In my experience, there wasn't a 'guilty' usage pattern or app that caused this for me.. I noticed that when the battery gauge showed around 60-70% my phone would start performing very poorly.. I'd reboot and when it booted, came back w/ critical low battery.
As I posted before, I reverted back to RFS and haven't had this issue yet.
Glad to see I'm not the only one having this annoying problem. I hate having a full battery and after 2 reboots I have a low battery. Its hard to believe that a reboot takes so much power.

3rd party launcher
So I was having a problem over the last few days trying to see what was eating up my memory and battery.
This was my solution to my battery drain:
If you have a 3rd party launcher, like LauncherPro, go turn on TouchWiz (via settings->applications->manage applications->3rd party launcher->clear defaults). Open up both TouchWiz and the Default Android launcher one at a time, and make sure you delete all of the widgets and anything that might be operating under the other launchers.
LauncherPro and ADW do not turn off TouchWiz, they are really just an overlay. So if you have, for instance, the Sprint TV widget on a home screen through TW, then it is still operating while you use LP or ADW. I use this example because it is a widget that Sprint has set up to automatically be placed on the home screen when you buy the phone.
Also, I would recommend looking at these three apps that might show you what is draining your battery: OS Monitor, Android Assistant, and/or Battery Doctor.
Hope this help you in some fashion to uncover whatever it is that draining your battery. If nothing here helps, I would do one of the battery calibration techniques here

OTA battery drain [XXJVK]

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

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 !

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.

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.

FIX and INVESTIGATION: Android OS (battery drain) problem on Gingerbread

CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!
Click HERE and read the bottom part for more details.
All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!
I'll give it a go! thnx

I hope we can help others avoid having this problem until there is a fixed solution.

Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.
Using cm7.
Sent from my HTC Desire using XDA App
You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!

Ridiculous ICS Battery Life

On Friday 1 June 2012, which is Friday last week at the time of writing, I gladly updated my phone through Kies after receiving word of the UK update being available from these very forums. Over the past week, I have noticed that my battery life is considerably worse since my upgrade to the new Android version and, when hearing of people hear who manage up to 36 hours of battery life through this phone, I really want to find out what they are doing exactly. At present, I have set the brightness at 1% (the minimum) and only up it to 40% when out in bright light conditions. At home, I also use the Screen Filter app which dims the screen further (I have this set to 50% of my already 1% brightness setting) and claims to improve battery on AMOLED devices. I also have Juice Defend Ultimate running on "Aggressive" mode along with the built-in power saving mode running as well. Yet, looking on CPU Spy, my phone still does not enter deep sleep which is needed to see a real improvement in battery life as far as I am aware. I have tried restarting the phone and also plugging it back into charge before unplugging it with the screen turned on as many have recommended. Any ideas what else I can do?
Uninstall juicedefender. Its not uncommon that it drains a lot more juice than it saves.
There is must be any Application that is hogging your battery.
Install better battery state... Find that application and uninstall that.
I am getting better battery life in ICS as compared to GB...

I have that app installed, but frankly have no idea how to use it very well. From what I can tell, it is Kik Messenger which is creating a partial wake lock (but I need that to send pictures to my friends), Juice Defender which is supposedly saving battery life and biggest partial wake lock is RILJ or something. But, that is caused from a weak signal and I get that regardless of network at my house. Besides moving, I cannot alter that. As for Juice Defender, I've heard nothing but positive reviews from it. My main aim is to get deep sleep working, but how?
Install Better Battery Stat and check what app is actually causing the problem :

first ,samsung ICS is poorly made ,second you have a high chance of bricking if you wipe your phone with their official kernels so don't do it.
third ,like others said ,juice defender (and any app of this sort) doesn't work anymore (android 2.2 and up) so just uninstall it.
fourth ,not entering deep sleep is mostly due to a rouge app ,and since wiping is not an option for you you need to hunt it down manually ,use better battery status (learn how to use it!!!) and uninstall any apps you don't need.
fifth ,get some knowledge then get rid of crappy touchwiz ROM and install CM9 ,you'll see a huge improvement in terms of performance and battery life.

Okay, well this is my first proper Android device (minus an old second-hand HTC Desire which had awful storage and I used for around one month). Secondly, I do know that other ROMs offer better performance and battery life but flashing them onto my phone is something I'm not very comfortable with and surely it would also void my warranty. I've only had the phone for four weeks and don't want it wrecked already.

I'm fairly new to android as well ,had an S2 (which was so good that I only rooted it ,no custom ROMs) for 5 months before the note and that's it.
but I rooted my note the first day I got it ,and installed a custom ROM less than a week later (was a total noob at the time but I read and learnt quickly) .
then CM9 arrived and I flashed that immediately and haven't regretted it so far.
but I had no warranty to begin with so.....
note that if there is something that can wreck your shinny new note ,then it's amsung official ICS update (read the announcement sticky on ICS and bricking) .
but how experts can explain the fact i face:
With every official and custom ROM i install, even CM9, my note keeps eating battery when in use plugged to the charger... it's unbelievable... I can't understand how it happens.
by the way: i always full wipe before installing any custom/official rom.

it can't happen ,I'd say you either have a faulty battery\charger or there is someting wrong with the phone itself

yes you can ,uninstall the violating apps ,learn to use better battery status ,you'll find that there is an app or two responsible for the wake locks ,thus preventing the phone from entering deep sleep.
or simply install every app and game that seems suspisious or poorly made ,and just keep the essential ones.
as for rooting ,it couldn't be simpler if done carefully and to the letter :
1.flash back to GB using PC ODIN
2.root it
3.backup your EFS folder (important , very important) search for it on the forums.
4. install custom ROMs (stay away from unsafe kernels please ,read the sticky thread about ICS kernels)
3. enjoy
use this guide
http://forum.xda-developers.com/showthread.php?t=1329360
yes there is an easy way to root while on stock ICS as per to this guide ,but I prefer you stay away from official ICS for the sole reason that it's dangerous.
remeber the key is to read and read and read ,in a month you could become a pro
on the other hand if you go the lazy way ,you could just end up with a bricked phone
also once you root ,your warranty is void ,though if you're careful you can return it to stock condition and they won't tell the difference
be careful

@Brad387
I have had mine for about 2 weeks. When I turned it on and did the initial setup it had a new software update which was ICS. Since then I have been having issues with deep sleep as well. I turned stuff on and off and it has been totally random what was preventing it from going to deep sleep.
I have done this trick that has been on this forum.
Put you phone to airplane mode.
Power it off completely
Remove battery for 20 seconds or more
put battery back in and power this thing back on
then turn off airplane mode.
This seems to have helped me get into deep sleep. BUT there have been instances of rogue crap going on. Like I was using Google maps with GPS on. When I got home and was done with my traffic mapping I turned off the GPS switch and turned off my phone. I checked an hour later and the battery had died 10% since I got home which was more than when I was driving. I checked Better Battery Stats and it showed that GPS was running that whole time. So I turned on GPS again in the toggle waited a couple seconds then turned it off again and bang it went into deep sleep. It sucks that I have to check crap on it all the time and have become a bit paranoid because the GPS glitch had my phone running pretty hot. Since then everything has been running well and deep sleeping.
There are other things I did do too and the below stuff is up to you if you wish to proceed. I rooted my phone which was very easy...at least for me. http://forum.xda-developers.com/showpost.php?p=20963730&postcount=3 this is what I used with no problem.
From there you can freeze a bunch of stuff you may not use like Social Hub, Accuweather etc etc.You will need Titanium for that though and root access.
I logged out of Latitude too which was on by default for some reason.
If I remember anything else I did I will hit you back here.
Bottom line was finally yesterday I was able to get thru the entire day without needing to plug in so there is light at the end of the tunnel...I hope.
Not sure if this has been mentioned but CPU Spy lets you see if you are getting into deep sleep mode and how much time you are in it along with the other CPU mhz that its running.
Hopefully this can help out a bit because I have been in the same boat and it has been driving me mad. Sorry for all the random thoughts too...I just typed them as I remembered things.

My phone does not seem to enter Deep Sleep, but runs constantly at 200 MHz instead. At present, after turning on the built-in power saving mode (not noticing any performance differs so can't even tell what it does), running Juice Defender Ultimate on aggressive and screen filter I burn around 2% per hour if I just leave my phone locked. Is that healthy?

Actually, there is something you can do about that!
Both Vodafone and Three can supply you with a Femtocell which can greatly improved your signal at home, and uses your home broadband as backhaul.
I know, because I have them!

Battery life of my Note was horrible after upgrade to ICS, and actually already quite bad the last month on GB2.3.6 (all unrooted).
It could get quite warm and often when opening my case the screen was already on.
So I did wipe my phone, reinstalled all apps and battery life has improved immensely.
I see several warnings here about chance to brick your phone when wiping on stock ROM, but not solving the battery drain is of course no option and we don't have a guarantee from Samsung for nothing...

Well, thanks for offering that advice but how expensive are these things? Also, I'm the only person on 3 in my house so kind of a waste really...

My phone does not seem to enter Deep Sleep, but runs constantly at 200 MHz instead. At present, after turning on the built-in power saving mode (not noticing any performance differs so can't even tell what it does), running Juice Defender Ultimate on aggressive and screen filter I burn around 2% per hour if I just leave my phone locked. Is that healthy?

your phone should not be running at 200MHz when you hit the sleep/power button. So if its in your pocket and the screen is off then 200MHz is not healthy. Something is running in the background. Have you tried the airplane mode battery trick yet? What I did when that was happening to me was...turn on the airplane mode, power off the phone, pull out batt for 20 secs, put batt in and power on phone, turn off airplane mode, then go to CPU Stats and clear it, then put phone back to sleep and let it sit for a half hour or less if you cant handle that wait like I couldnt. Go back to CPU Stats and and click refresh and see if it helped and if your phone went into deep sleep.
