Hi,
I'm currently using JuicePlotter to see how my battery drains over time and this past night I think it drained more than it should (or maybe not).
For the ones who don't know, JuicePlotter runs in the background (of course) analyzing your battery, that too wastes battery juice of course. Thought, the app dev says on his website:
Perhaps the most important feature of JuicePlotter is that - unlike all similar apps and widgets - it's very battery friendly;

So I'm not sure if the problem lies on JuicePlotter or not, I'll have to test it one night without it...
This is how JuicePlotter displays it's graph:
The coloured bands along the graph show your screen brightness, radio usage, charging status and battery temperature. Just scroll around to find precise information and make sense of the different colours.

I went to bed at 4:10 with the battery at 97%. Around 13:00, it was at 89% and I didn't receive any calls/messages/mails/whatever during the night. The WiFi/3G was off all night along with the screen of course. The battery temperature remained the same too. I don't know if it makes a difference but I normally turn off Auto-Sync if the WiFi is off too.
Is it normal to lose 8% of battery juice in 9h in standby? I think it's a bit too much, but I don't know... Does the same happens to you too? What else cloud it be?
Interesting looking app. I've never noticed much of a lose overnight. Just installed the app, will fully charge and give you an update tomorrow.
Also how's the cell reception in your area? I've heard it can drain the battery a far bit if the reception is low.

I'll have to do more testing but I think it's the app's problem... Tonight, I went to bed with 83% and it was exactly the same when I woke up...
I fully charged mine last night and turned on JuicePlotter. Still showing 100% this morning. Both in the app and on the phones battery indicator (in the notification bar). Do you know of any other apps similar to this that could be run in tandem?
Weird, Battery Graph also does the same thing...
This needs more days of testing on my part...
My battery goes from 100% - 0% in about 16hrs... doesn't matter how much I use the phone or not.
I have BatteryGraph but the results don't really mean anything to me as it just shows battery life vs time on a scale.
I'll try JuicePlotter to see if I can pin down exactly what's causing my terrible battery life.
I have a feeling it's running at full speed even when in standby but I'm not sure how to check if this is the case. Any ideas?
EDIT: Looking at BatteryGraph I've lost 15% in around 1hr... nothing unusual going on with my phone that I know about... just standard stuff running in the background. Perhaps the battery itself is simply past it's best.

Wow that is terrible, try apps like Taskpanel and when you add programs to your auto kill list the program kills the programs as long as they are running in the background when the screen is off, however if you are on lets say your browser and you don't go to your homescreen the screen goes off into stand by it will not kill the app. Also try draining your battery to the point it shuts down by itself, plug it in let it charge for a bit, boot into recovery wipe battery stats start up the phone or leave it off (your choice) and let it charge fully. Are you using setcpu or OC Widget or anything? If you are using SetCPU make a profile for when screen is off and make it underclocked like 264 Mhz to 480Mhz, or with OC Widget tick the 'use different screen frequencies' (don't remember what it is called since I don't use it) and do the same; I like SetCPU better because when you turn the screen on it switches profile faster where as OC Widget takes its time however with SetCPU do not use the widget it will cause Sense to FC and I'm not sure about Vanilla.
Hope this makes sense since all my ideas are said at once.

The way I've learned to recalibrate the battery is to let it go down to 5%, boot phone into recovery and wipe batterystats, then power off the phone. Let the phone charge until the green led is on without turning it on. Then turn on and use the phone as usual. Learned it over at modaco. Worked as a charm, and batterytime was improved. I have personally experienced strange batterybehaviour after periods with flashing a lot of roms.

Here.
That's interesting...
Cause I've been playing with ROMs latetly, creating my own, testing hacks and stuff... And most of the time the phone is plugged and the battery is charged, during the flashing process it's using the battery and then it charges again. I also have to leave from time to time and when I get back I continue my stuff, meaning I'm charging the battery at high levels.
I'll have to try that calibrate method...
For now, for the past 2 nights, with JuicePlotter off, I've noticed the battery level did not change at all during the night. Tonight I'm going to try one more time with JuicePlotter on...

Wiped battery stats at 5% last night, let the phone die and then charged whislt off until green light came on. Been keeping an eye on it all day and there has been a noticable improvement.
The phone came off charge at around 2am (so around 12hrs ago) and it has only lost 20%, which is a lot better than I was getting before.
It was probably just due to me messing about with some many ROMs and update zips lately as I tend not to have too much crap running in the background (I use OSMonitor).
I will look into setCPU but I remember trying it before with VR12 and it ended up causing some weird problems meaning I needed to do a full wipe to get everything working again.
Thanks for the help
This night, with JuicePlotter on, I only lost 1%, seems reasonable now... I don't know why that one time I lost 8% during the night. Maybe an isolated case? Something was probably running when it shouldn't, I just don't know what.
Ive noticed serious battery drain since I first bought this fascinate from telus. On 2.1it lasted around 11 hours. Since upgrading to 2.2 leak, id say 8 hoirs max with only approx 1 hour of uusage and the rest on standby. I turned of sync, auto brightnrss and turned brightndss as.low as possible. I make sure no apps r running in the background. Yet it still dies superfast. Is this a issue with my battery thr phone itself or firmware or kernal. Its been a week of trying to find the problem so any help would b greatly appreciated. At tgis time im running 2.2 leak with all the files it came with and no root. Thx in advNce
And hour and 12 minutes with about 30 min of internwt surfing and im down to 80 percent WTF
I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

sounds about average for a fascinate....
I'm on telus as well and also have terrible battery life, I've found no fix other than completely turning off Data using the toggle when holding the power button. Flashing a new rom might fix this but I've been to scared to since I bricked a phone trying it the first time. Hopefully when/if ever we get a 2.3 update it fixes this
Does anyone know where one can get an extended battery for this? I picked one up but it's for the friggin Verizon US version, and the battery cover isn't compatible, even though the battery fits(camera doesn't align, speaker's not even close).
Seriously, the American counterpart's accessories have been my biggest frustration with this phone, next to battery life...
Thought I'd give this a bump. The battery life on this Telus Fascinate 4G is truly disappointing and jumping through hoops trying to find and kill apps and services with and without utilities is wasting far too much of my time.
Anybody get a good handle on this?
Bump for same problem.
Samsung Fascinate SCH-i500 Verizon
Running unmodified and unrooted. The phone itself works perfect. No problems other than the phone seriously eats battery. Yes the battery is still good and nothing wrong with it. Plugged in it charges super slowly. And the screen itself takes more than it provides. So i did the following.
A. Changed battery to a known working one.
B. Check with car charger and a home charger. As well as official samsung charger.
C. Gave a ROM a try. Running Dirty Unicorn. Lowered cpu to 800 max and 100 min.
D. Turned display to 50% Brightness.
My only try now is to try a different kernel or something. Im also thinking that the display itself is the culprit somehow eating to much voltage.
Or the gpu. The phones operating temps are good.
I have another post here http://forum.xda-developers.com/showthread.php?t=2430393 relating to where i have a USB problem and need help figuring it out. There has not been any replies. So i am taking upon myself to learn more. Ive worked with 3 Droid Milestones. Hopefully these two i500s will not be to hard. I need help on this new i500 to see if its not the motherboard. The charging port is on the motherboard and if this replacement eats batteries , then the point would be mute to use it for a working USB. A conundrum.
Do i try a different kernel or somthing else. Whats my next step.. Please help.

what else do you have running?
what is the battery life overall usage? and screen usage hours?
screen is always gonna be the highest consumer of your battery
50% still pretty high unless you are out in sunlight, I keep mine between 0 and 30 % unless in sunlight
you can try running the greenify app from playstore.
what king of life are you expecting to get? anywhere between 6hrs to 24 hours total phone battery life is about average depending on how heavy user or how much in standby mode.

Its been on the charger since i posted. its only at 56%
3h 25m left
Screen 55%
Cell Standby 9%
SystemUI 7%
com.maxmpz.audioplayer 7%
Android System 7%
Its defiantly got something wrong as even though it says 56% if I unplug it, it will die in about 10 min. Even with a fully charged battery it does the same. Yes i also waited until 100% and wiped batt stats and at 3% left wiped stats. Screen is in standby

I would recommend going here
[APP][2.1+][16 Apr. - V1.13.4] BetterBatteryStats
you can get better logs and information, plus if something is not easily visible to what is causing problems you can post up a log file for them to look at.

I had installed the program and it didn't really show anything abnormal. Although after installing the Bat Meter, when i shutdown it killed the phone till i ODIN. So tried on the other phone as well. Same thing. Install it and compared notes. Reboot phone and had to ODIN. So maybe bad app? Well whatever. I didn't see anything unusual. Although I did notice something strange about the phone that's bad with charging. I already eliminated the battery as the problem as well as charger. But the phone that is eating battery faster than it can charge, it gets warmer at idle than the other phone. It charged just super super tiny faster than the battery eats using just idle display on lock-screen. As well this phone also with a fully charged battery will read 100% But after about 21 minutes of poweramp at 33% volume on headphones will read about 52%. Then sitting rest at idle no display from 52% down to about 14% popup around another 5 min. Then completely dead in about 3 minutes. And the phone is pretty warm. Today it was ambient temp of around 87* outside and sitting in shade and it was hot enough that it wasn't comfortable on my cheek for more than 20 seconds. Half the time the temps are normal. Now remember I'm not running overclock and actually under clocked to 800. Ive tried 3 different roms with diff kernels and same. Could it possibly be a bad heat-sink? And the extra heat is killing battery?
[Q] Battery Drain
I recently was given a Fascinate and am having similar problems. I was told the phone had a bad battery, so I ordered a replacement. Once I got the new battery in, I flashed the phone with the Carbon ROM [the phone was unlocked, but running the OTA 2.3.5 I believe]. Everything seemed to be working fine the first week or two, but now there appears to be a serious battery drain or leak after I power the phone down. I can charge the phone to 100%, power it on and use it for a period of time, then power it down with 90% or more battery life, but when I turn the phone back on, the battery will either be really low, or completely dead, where the phone won't respond at all until I plug the charger back in.
I reflashed the phone with an AOKP ROM to see if that'd make a difference, but it didn't. I tried using the first battery and the drain/leak still persists. The commonality between the two roms is the Devil kernel, so I'm going to flash a different ROM with a different kernel to see if that makes a difference. I also installed the app mentioned above to log the battery stats/usage to see if anything stands out there.
Has anyone experienced something similiar - the Fascinate consuming battery life while powered off?
Yeah the power off leak does seem to exist.
Can't remember the cause though.
I've not tried to really confirm,, but try popping the battery out then back in after you have powered off,,, then check after it has sat overnight to see if drain still exist..
Mine i just always leave on a charger overnight.
.
[Q]
Thanks for the reply. I'll try that. I've left the phone on today, just put it to sleep during periods of inactivity, and the battery is currently at 75% with occasional mild use after 8+ hours "on".
[edit 11-29-13]
After almost two weeks of use, I can confirm that if I power the phone down and do nothing else, the battery will continue to drain to 0%. If I power the phone down then remove and replace the battery, it's fine. It's an extra step, but it works. Thanks again.

In my case, after updating to new firmware and software my battery full capacity indicator has become sort of crazy (for the worst).
Before updating I got a solid 1390 mAh always. Now It depends on the day, but It never surpases the 1270 mAh. Barrier.
Today I´m getting a poor 1170 mAh.
Strange thing.
Anyone else experiencing this issue?

From my review, my battery seems to be getting better now, first week after the update, battery was dreadful, it seems to be a whole lot better now. Give it a week, if it continues, email Nokia support, since you hopefully have your warranty, they'll check and replace it if it's faulty, I'm suffering from some horrible notification bug, that's worse, getting your notification when you enter message/whatsapp...-_-
Have same problem. The last update have reduced full charge capacity from 1420 mA to 1303 mA and it's still decreasing every charge. Hope is's soft bug, otherwise nokia should exchange killed batteries phones.
Nokia says not to trust their diagnostics tool when it comes to degrading capacity. The battery should be fine anyway unless it reports less than 1000mAh.
Nokia's biggest mistake was making the Diagnostics available to every user. Now everybody thinks Nokia stole their precious mAh...
Note: It doesn't even matter the update gave us some hours in autonomy.
Yep. Without it most users would actually enjoy their phones.
So the Diagnostics tool gives a bad reading?
Today, when I plugged the charger off, the charge percent inmediately went down from 100% to 98%. Maybe there´s some kind of software bug thay doesn´t give the real battery performance.
P.S.: I actually enjoy my phone. Love it.

This happened to me also this morning. Took my phone off charge, unlocked it and then was at 98% but going to keep an eye on it throughout the day. I got roughly 15 hours use yesterday and 5 hours of that was when i was at work.
I am getting terrible battery life after the update. 100 % at last mid night. By the morning it is at 85%. It seems the battery life got worsen by a 40 % decrease before the update.
Should I restore my Lumia 800?
I get weird battery issue on my latest 800. About every second charge the battery drains very fast doing nothing. The next charge it is fine. Next after that it can drain. And so it goes. Something fishy with software indeed. It was preloaded with 11501 from factory so I have not updated myself.
Nokia need to take a detailed look at this. As it is now they fully think the issue is fixed when in face it is not. As the topic implies it actually made things worse compared to old firmware. Those 15% charge that were lost in old firmware it lasted longer anyway because it had no drain.

I have made a factory reset just for the heck of it. Also I have recently started rebooting my phone with the charger plugged after every charge and then unplug when it is booted again. So far no drain after doing so but too early to make any conclusions.
I reseted the phone on a charge cycle with drain and after the reset the drain stopped. So something weird is going on. Hadn't really installed apps etc... syncing/location etc off...

Unfortunately I do not even have the good days result. After I updated my Lumia to .11500 my battery drains really quick with doing nothing. Before going to sleep I had about 60%, waking up it was empty, in 6 hours! Before I could last about 1.5 days with my phone. Hardly 10 hours with normal use. 3G on but wifi and bt off.
Does anyone know how to change this or to change it back to the earlier version of software?
I love this phone and its OS, but the battery consumption is just wrong!
Thanks.

Same issue with battery drain. Not that frequent though. Two times in two weeks. It´s random I think. Thing is that I´ve noticed that it has occurred when the phone shows maximum than my average battery capacity.
Normally phone shows 1170 mAh when fully charged. Strangely enough I get a very decent battery life. More than 24 hours with normal to heavy use.
But today it showed 1370 mAh fully charged and it´s not passed 12 hour barrier.

Since I made that factory reset the drain has not come back so far. Now I get good battery life and it's usually at 70% when I go to sleep at nights with moderate use throughout the day.
Is this what everyone is doing for best battery or is it just me?
Used to get heavy drain when I get the mobile:
I had to do below:
1) Location services off - i use very low though.
2) Removing people tile
3) Display brightness - LOW
4) Settings->Applications->Games->Connect to Xbox LIVE-> OFF
(with ON, used to drain battery alot atleast for me)
5) Settings->Background tasks->Weather->Off
(not sure of this, but I don't use it so I switched off)
6) Removing XBox Live Tile (In fact all live tiles like App Highlights etc...)
7) Date+time -> Set automatically -> OFFFF (I don't think we need it unless we go to other country)
8) Phone Update -> Turn off notifications
By the way,
I use push email outlook on always

Just restore your backup in Zune. Connect the phone, go to the phone tab. Settings -> updates -> restore. Good luck!

What to do. Now a days all smart phones come with great features and poor battery life.
By the way, anybody knows how to turn off fast dormancy in our lumia 800? I used to get much better battery life by turning off fast dormancy in android phones ( obviously my network is not supporting the feature though)

So you're limiting the phones key features for a battery problem? Why not contact Nokia? I must be honest, if Nokia were to tell me to switch off so many features of my phone, I would tell them to kindly p*** off, as I've had many phones before it that didn't pose a problem like this, if it's a fault, they should act to it, not make you rectify their mistakes. At the end of the day, if you broke your phone accidently, would they fix it for you? So why should you?
Hey guys.
It seems like almost everyone with battery drain issues has Android OS at the top of their battery stats.
I just want to share my experiences with this particular Bug.
Maybe it will help anyone. Please share if it also helped with your problem.
I had the Android OS bug since I dropped my phone a few months ago and had the screen replaced. The guy who replaced it (official Vodafone shop employee) said that they didn't just replace the screen and that something else was also damaged (they didn't say what) so they also replaced the rest. Well, that's when the Android OS problems started. I tried many ROMs and many Kernels. Sometimes the problem went away for an hour or so, but it always came back.
Then I finally decided to use BetterBatteryStats two days ago (I really should have done this earlier, I know...). I came to the conclusion that I had some sort of the well-known "fuel_alerted" bug, since fuel_alerted was the service that kept my phone from going into Deep Sleep.
This bug should have been fixed long ago but for me it somehow still persists, even on stock JB.
It didn't only drain a lot of battery (I had 8-10h maximum without doing much), it also used up a lot of CPU time, effectively slowing down the whole system to the point that I wasn't able to use Spotify on my phone without severe stuttering.
Well. I found a solution to the fuel_alerted bug.
The procedure is: turning airplane mode on, shutting phone off, taking out battery, putting it back in after a few minutes, turning phone back on.
This solved the problem. No more Android OS draining the power. Phone goes into Deep Sleep again. Only 2% drain after an hour. Spotify runs smoothly again. Yeah!
BUT well... It seems like the problem comes back randomly for me, today I had to replace the battery 5 times...
Now I am trying to strictly follow another "rule" to keep the problem from coming back: Always waking and unlocking the phone before plugging it in or out of power. I never did this before so it could have been the cause of the bug. Now let's see how long it stays bug-free.
If it still doesn't help, I guess I have to conclude it's some kind of hardware problem, which could only be solved by Samsung...
EDIT: Nope. Problem still there. So not really a fix, but maybe still helpful for somebody.
Okay, what ROM are you on?

It's the up-to-date stock Samsung ROM I guess. See attachment for infos.
Damn, it seems like the problem just came back without me doing much. I only checked BetterBatteryStats every 30 minutes or so and recieved 1 SMS just a minute ago. Seems like the bug started 20 minutes ago, when battery was around 78%. Now it's draining battery like hell again, Spotify stutters, Deep Sleep won't work...
Guess I'll have to pull the battery again.
Since I'm pretty new to all this: What kind of information would be useful to narrow down the source of the problem?
I can provide my BetterBatteryStats screenshots and logcat/dmesg files as well as my Android Battery Stats screenshots.
Is there anything else I could post?
Yeah, screen shots of partial and kernel wakelocks.

I just rebooted the phone, waited for a few minutes and took screenshots.
Here they are.
Okay, this is what you need to do now, drain it empty, charge it (while phone off) till 100 %. Remove the battery, wait for 90 sec or so, put it back and power on.
It's a placebo, but it might work.

Okay, I will try and do the charging overnight. Thanks!

I don't know much about kernel and ROM stuff, but I was just wondering...
As far as I understand, the fuel_alerted thing turns on if the battery charge goes below a certain threshold. The old bug with it was that, when recharging, the fuel_alerted thing would sometimes still stay on, even if battery charge is no longer critical.
Could it somehow be possible that this threshold is not set to 15% for me, but something around 80% due to some horrible bug?
This would explain why it suddenly turned on at around 80% when everything was fine before.
We're trying to adjust your fuel gauge and sort of calibrating your battery.
Sent from the little guy
Okay, I did exactly what you recommended.
Everything went well for about 2.5 hours.
Then the fuel_alerted process began again, but this time only for a short while apparently.
It took about 5 minutes kernel wakelock time in a 30 minutes measurement.
Way less than usual and when I check now, it's no longer active.
So. The problem might still be there, or it might not.
Do you recommend going through a few more recharge cycles to get the gauge set properly or do you think this won't make it better?
By the way, thanks for your quick responses!

Not really.
Now, when it gets to 15% or so plug it in (while phone ON), get battery calibration from play store.
Run the app, when it gets to 100 % hit calibrate. Plug off the device. Turn off.
Take out the battery for 90 sec again, reinsert it and power it on.
That calibration app is another placebo but as I said before, placebos sometimes work.

Since the battery calibration app requires Root access, I flashed a Dorimanx kernel a few hours ago. Then I did a factory reset and the battery-removal thing. 5 hours have passed now without the bug, 3h of which were without wireless access (maybe it correlates with that).
I'll now let the battery (slowly) drain below 15% and then recharge it with phone on overnight. I will use the battery calibration tomorrow and will inform you about the results later.
Thanks man!
Good to know

I did the battery calibration. Bug is still there, no changes
Post you battery details and a couple of BBS screens.
Sent from the little guy
Okay, here are some screenshots.
From the graph you can clearly see when the bug started.
Is it normal to have >26 kworker processes running?
Something else that concerns me: >2h without or with unknown signal. The whole day I was in an inner city area where the signal should be good...
Can you conclude anything from the screenshots?
I will now try something which I also should have tried earlier
I have a spare battery (not original samsung, less capacity) which I just put into the phone.
I'll let it fully charge with phone off and then I will try if the problem persists even with the other battery.
If it doesn't, the problem might come from the battery itself...
Is this a good idea?
No it's not.
You gotta post detailed info there, we can only guess what's draining your battery.
Sent from the little guy
Okay... I posted the screenshots you asked for...
What more should I post?
Just wondering if this is the same for everyone else. My battery is running out insanely quickly. 11 percent on 15 minutes of screen time easy. I've done multiple factory resets but this is a little silly to the point I almost want to return the phone. Anyone else that's using a battery stats app... can you tell me if the kernel is the highest? Mine always is consistently by an insane amount and I'll always have about 1000+ wake locks on my msm_hsic_host and main processes.

I am seeing that too, battery life has been HORRIBLE so far. I love this phone, and I am hoping it will get better with a few charges and discharges, they will probably (hopefully) be releasing some updates to correct any issues soon. According to my battery app, HTC Sense is responsible for 18%, Google Play Store at 14%.
Edit-Mine has been unplugged for 1 hour 52 minutes, and I have only played some Google Music and done a little surfing, and it's down to 84%, that's a pretty big decline in so short a time, especially considering I haven't done anything really intensive. My battery stats program is saying it is discharging at a rate of 1% every 6 minutes. This is the app I'm using-
https://play.google.com/store/apps/...n.beta&feature=nav_result#?t=W251bGwsMSwyLDNd
I am definitely seeing this being an issue. I have lost 8% battery in 45min kernel was 25% and android system was 12.2%. I have only had my phone for a day, so I am hoping that it will course correct itself.
Try the SnapDragon guru app it helped me out greatly. Although I haven't had huge drops like you guys are reporting.
