mega battery drainage, help me figure out why. - Galaxy S I9000 Q&A, Help & Troubleshooting

Ok. so iam on darkys rom 9.3, used wipe and ever since my battery life has been bad since.
Take today for example,i pulled my phone off charge at 7isham listend to music for about 45mins, had possibly 3 hours of sporadic internet usage 3g/hsdpa, always turning off the 3g after usage. At about 130pm i had to switch to my 2nd battery.
this is a typical day for me, so its preeeety frustrating.
anyone have any ideas why or similar experiance and can share some wisdom?
cheers!

The first time you use the phone after a flash, the battery will be bad. A couple things to note:
Did you flash with 100% battery? A lot of people say this is necessary.
Did you calibrate it yet? When you do a new flash, use the phone until it is dead. Charge it without turning it on. When the battery is 100%, go into recovery and wipe the battery stats. Then use the phone again until it dies. After that normal charging patterns.
Some people say that they get better battery life with certain kernels, and whether or not you have lagfixes. I use speedmod and I'm getting great battery life.
Check all of these and see if anything helps.

Clue your rom if you did not have battery drain before .

First think: have you installed any programs that need constant internet connection, like skype or facebook? To check whether this is a possibility check battery history, when cell standby is absurdly high even though the screen was on some time it's a good indicator something is constantly downloading (That only works if you used your phone since unplug, I have 72% for cell standby because I never turned the screen on since I charged it: )
If you ruled that out check whether your modem is appropriate for your region.
After that you should wait and let the phone run down to very low percentage or even let it turn off itself. I don't believe in wiping the battery stats, the battery will calibrate itself with every charging cycle. just let it drop under 10-20% and then charge fully. That helps me.
If the drain does not get better after 2-3days fully charge your phone and reflash the rom with the kernel

I've got the exact same problem with my girlfriends SGS. I got her this phone because it is a bit smaller and lighter than my desire HD, and it supposedly has better battery life....but at the moment I'm not seeing it.
Her phone seems to go at 30-80mAh at sleep, whereas mine will be under 5. She doesn't have any apps that I don't, and I can't figure what is causing the drain based on the running apps.

How do you know if the modem is appropriate for your region? I've been dying to find that answer, searched several places but no luck. How do you pick a modem. I have an international GT-I9000 but live in north america.
Thanks

On the first link there was a tip to make wifi sleep when the screens off, I did this an noticed a major change in my standby(screen off) battery life, it dropped 1% in like 6 hours rather than like nearly 10% Nisha, which I was noticing before.

I know, I read that post many times, but it's misleading, the country listed for each modem is just where the reporter tested out, not by any means comprehensively listing all the countries in which that modem would work well

Battery Problem

Hey,
I thought updated firmware fixed the stock messaging battery issue?
My phone had a full charge and 2 hours later, 15 texts sent/received, im down to 87% Just unlocking my screen now, i went from 89% to 87%!!
What is going on!! I have SMS popup.
I was just looking up stuff because my phone lately has been draining fast and I really have not been using it. I am at 65% and I have barely been using it today.It came off the charge at 10 and it's 12:30 now. Something is up. I can't seem to find an app that tells me which apps are using data in the background cause I think that might be my problem. Also, I checked Spare Parts and it said Facebook was Partially Awake for over 30 mins with only 14 hours up time. Hmm. I don't even have Facebook set to auto sync.

Post your up and awake times.
I've had this issue since I had this phone. I go to school with 100% charge at 8:30 and by the time I get out 12:30 it's usually around 55-65% with very limited usage. I've had fresh rom, modaco, and all the available aosp roms and it's the same issue no matter what so I just learned that if I want this phone it's has to live on the charger when I don't use it.

How many bars do you get in the classroom? Poor phone signal will drain a phone very fast. There's a couple conference rooms here where I work in the basement where phones get no signal and I see the battery on my phone drain much faster. This happened on all my previous phones as well (HTC Mogul, Diamond, etc.).

In school.....
how does it perform outside of school.. when you are at home on weekends or other places????
I am only guessing here..
but at big university, the buildings are very big.. and sometimes in hard to get receptions areas...
so, the phone might be looking for the phone network, and that will drain the battery very fast...
sorry, where can I find up and awake times? Total newbie I know...
I found "Time spent without sleeping: 36 Minutes"
I also noticed that my battery is at 73% now for SysTray Monitor but the HTC battery icon is nowhere near 1/4th gone. Looks like 1/10th is gone.
battery drain at school
another thing to consider is that if the school has wifi available and your's is turned on on the phone, it may be connecting or attempting to connect, to the school's wifi. just a thought. i tend to turn mine off, as well as my bluetooth headset, when i go to work. seems to help, but i also have a battery drain problem. this doesn't solve it, but, like i said, it helps. i also turn my screen off manually, rather than just setting it down and letting the screen turn off automatically. every bit of energy saved helps, but it will only get about 25-50 percent better. doesn't completely solve the battery drain problem. if anyone finds a sure-fire way to solve this problem, please post and post and post. i've seen this problem arise all over the place on XDA as well as other sites. may even start a new thread with the solution so it will pop up in the search.

I guess this isn't something I have not really looked at but now it does make sense, b/c in some rooms it is hit or miss so i'll just throw it into airplane mode when i'm indoors and see how that goes. Thanks
by the way...
i am also experiencing a situation where when i plug my phone in to charge, it will charge regularly through about 80%, then it seems to fly through the last 20% within a matter of minutes. it was at 82% last night when i checked it (it was already on the charger for about an hour). then i put a bowl of soup in the microwave for 2 1/2 minutes. when my soup was done i just happened to look at my phone, and it was already up to 96%! that just can't be accurate. something is causing it to either charge improperly or the battery charge reading is somehow inaccurate. anyone else experiencing this strangeness when charging that also has the battery drain problem? as many times as i've seen these problems posted together, they have got to be related to each other.
There is an option to wipe the battery in Recovery.
Charge the phone fully, and then Wipe the battery while it is still 100% charged. This will help the battery reflect a more accurate percentage.

LOL.. Point taken. Thanks
well, are you guys using modaco's custom ROM or kernel? there's an issue with the power management that HTC didn't include when the released the kernel... but i'm not completely sure what causes it.

Need Help w/ Battery (Yes, I've done my research as best I could)

Ok, so ever since I upgraded to CM6 (which I LOVE) I've had serious battery issues and I've tried to fix it by installing Pershoot's kernel and I have SetCPU to underclock in depending on what battery life it's at. Also, I've wiped my battery stats and I've calibrated my battery already.
Today my battery was at 64% after only 3hr and 26min. I don't have GPS on, auto backlight is on, 3g/2g and sync are on. If it makes any difference I have the Korean radio installed (which btw improved my reception a lot! ). After about 9hrs and half, my nexus one died. As per usage, I wouldn't say it's much at all because I'm in class most of the time and I've only talked on the phone for about 1 min, browsed a few websites, and sent only a few texts.
I keep reading on the forums about how people are getting 1-2% lower per hour while on standby but the % I reported earlier, my battery's draining at over 9%/hr!
I really just want to be one of those people that can say that "I still have 50% left after 12 hours!" lol
So, is there anything else I can to increase battery life? Is my battery just crap? Any recommended setCPU profiles?
If you're one of the users that get really good battery life from your Nexus One, please tell me what you did to get it that high! Thanks!
Don't use setCPU to manage battery life, only to overclock. It overrides the kernel's settings. Sounds like you need to wipe and flash the rom again. Then gradually add applications you want, something is sucking battery life.
Last, buy a new battery.
CM6 has less than stellar battery life. If you check the "help with my battery life" type threads, you will see most of the OP's have CM6 as their ROM. Try another ROM, you will get better results.

Quoted for lies
I'm using CM6 and I get between 22-32 hours on a single charge. I just use the kernel that comes with it and i almost always have sync on. No GPS or bluetooth though.
Are you using a battery you purchased on ebay? Or are you using the stock battery? ebay batteries last me about 9-12 hours and die. The stock battery is amazing
Exactly the same situation as you:
CM6.
N1.
Student.
Experiences massive drainage in short amounts of time with low usage.
Tried everything.
I'll now be trying Enomther, because yes I have heard CM6 users get worse battery life.
Just a viewpoint on what I'm facing. For the past week I've gone to bed with 100% battery and woken up ~7 hours later on 75%. I've tried WCDMA and GSM auto settings and neither male a difference.

Thanks, I'm glad I'm not the only one with this problem. I thought I was being an idiot by doing something wrong...
I've calibrated my battery several times already while trying to fix this issue. Could that have killed my battery life?
1) Discharging the battery below 10-15% is bad for the battery, doing it many time will destroy the battery, making it last just about nothing.
2) Check CPU usage - download System Monitor or some other app like that, and check the running frequency of the phone. When you just run the program and don't touch the phone, it should float around 300 MHz. If you have it locked on 998MHz - you have an app that got your CPU stuck in a loop.
3) Download some app that stores battery stats, and check your discharge current and battery capacity - that way you'll know if it's your battery dead or your apps drawing the juice.
Sorry, double post.

crap, all the guides that i've read regarding calibration told me to discharge it completely.
My CPU usage seemed normal. It was stable at around 245 and would jump up to 998 from time to time that doesn't last for more than half a second though.
My battery seems to be in good condition as it's labeled as "healthy" by my battery apps and the voltage seemed normal....

Do a nandroid back-up of CM6, and then try out the above ROM. You can always go right back to CM at any time.
For calibration, complete discharge is necessary. Doing it once is not too harmful. As long as the battery is reported "healthy" - you're ok.
There are apps that will show you the approximate capacity of your battery in numbers. Try to find one like that.
Please check discharge current and voltage over time. It doesn't make sense that a phone on 245 MHz in sleep mode will draw the current required to discharge 10%/hour.
in same boat as OP
im in the same position as the OP
student.
dont use phone for nearly 7 hrs a day
backlight on lowest, gps and bluetooth off.
ive been looking around for answers (hence why im reading this)
when class gets out ive gone from 100% to nearly 65%
running cm6 and ive wiped battery,
about to switch ROM, maybe that'll help.

Awesome, if you find a fix let me know please.
I haven't been able to do any of the suggestions yet but (when it comes to flashing) but I do have an update that might shine more light on this issue.
Today in class I noticed that my N1 was warm when it was in my pocket but nothing was running and gps and bluetooth was off. I checked the temp of my battery it was at 36.1C while it's usually at 30-31C when I'm not doing anything.
Also, I checked spare parts this morning and found that, while I was asleep, my N1 was not asleep for half that time but my screen on for only 4% of that time (probably from my messing with it before and a little bit after sleep).
I've checked to see if anything is running in the background that might lead to this but so far none of my apps should drain my battery that much while I was asleep.
Is this normal? Shouldn't my phone be mostly in sleep mode when I'm asleep since I'm not doing anything to it? As for the battery heating up, do y'all think it's a faulty battery or the fault of the OS?
Thanks again for all of y'all's helpful replies!

About battery heating...
I checked and mine is at 75-78F while in class. My n1 is also in a case, so for it to be that low is good. Just thought to throw that in as a comparison.
Also i've switched ROMs to help with battery, no luck there. Still experience 7-8% drop per hour.
I've been keeping my phone off now at school, which has helped, though I still lose nearly 15% while it's off.

Batery Usage HELP!!!!

I am currently running 5.7.893 rooted and I have been having battery issues lately. The problem is I sit here , 1h 37m off of the charger and the phone is reading 80%. The breakdown looks like this:
Android OS 39%
Maps 12%
Display 11%
WiFi 9%
and a couple other small things.
It seems like my phone is never going into standby and I can't figure out why. I've checked a bunch of things and no luck. If I click the chart at the top of battery info, I see "phone signal" taking a constant drain on the battery.
The only thing I can think of to do is to factory reset the phone and see if that helps.
Any ideas?
I would recommend the Factory Reset. But first, is there a chance it's a battery calibration issue? Have you checked the actual mV reading with an apps such as Spare Parts?
Before you do the reset, make sure the Backup and Restore are checked in the Privacy setting. And then after the reset make sure you check the two options presented about Backup and Restore. These show during the new setup after you enter you gmail info. Also, if not in a 4G area, if possible connect to wifi before you finish the setup as your apps will start downloading automatically. Good luck.
I did try battery calibration first without luck. I just did the factory reset and I'm charging to 100% now. I haven't done the titanium backup restore, because I want to see if installing the apps I use from scratch again will fix it rather than just restoring them.

That's a good idea. Lately I've been letting Google install the apps and then I use Titanium to only restore data to select apps (such as Tapatalk).

Well, now I'm confused. I haven't installed any apps yet after the factory reset. after 2h 50m of just sitting there, it's reporting:
90% still
32% Android OS
20% phone idle
16% display
16% cell standby
10% wifi
looks much better, but does this look right? I would have expected cell standby to be the dominant process.
wifi
Having the exact same problem. Seems to be draining battery at the same rate it was before the update (which was supposed to fix battery drain or so I thought). I'm-a try a little experimenting before doing a factory reset (HATE doing them). Right now, I'm theorizing the built-in Google backup process might be responsible because I've never seen so much drain before and I usually turn Google backup off since I use TiBu but forgot to disable it after the update.
In the meantime, I've prepared myself for the battery issues by purchasing the battery dock and an extra battery for three total. Swapping batteries is better than staying tethered to a wall charger so much.
EDIT 1: Looks like that did nothing. Next, I'll try wiping cache (didn't do this when I updated)
EDIT 2: Looks like not much change from wiping cache. Guess I will be trying that reset.
EDIT 3: Looks like I use the phrase "looks like" too much. However, the factory reset appears to have resolved the issue, at least initially. Fired up the phone and Android OS was only 8% of the battery usage after 10-15 minutes. Will check back if anything changes.
Disable push sync on your device.
changing and controlling your sync settings will solve your standby issues and improve your battery life.

I think a better way of looking it this is that your phone isn't spending 32% of its time using the Android OS and only 20% of its time being idle. That's just how much battery they are using. Your phone could be spending 3 hours "idle" and only 15 minutes using the OS and this is how it could read. It's just how much battery each one is using, not how much time each one is spending doing that particular task.

I'm with noosympathy on that one.
A ROM will improve better life but not that much... maybe if you ran it on 3G only, but then again, that is a maybe.
A lot of your battery is used when your phone is syncing.
When connected to 4G, it uses a lot of power trying to get a signal as well.
To help get some more life out of your battery, disable push syncing and notifications.
I set mine to 1 hour because I don't like being bothered for stupid bs.
When your in a place where you know you don't get 4G, turn it off. It is going to try to aquire a 4g signal while running on 3G the whole time draining your battery.
If am out and don't need 4G, I turn it off. It only takes about 15 seconds to turn it back on and have it link up.
Do you really need to be on 4G to play angry birds?
I recommend installing tasker. You can program stuff like this into it.

Maybe I'm weird, but I don't have a need for 4G data all the time. 95% of the time I leave it turned off and battery life is quite nice with the Bionic just riding on 3G. If I'm in a situation where 4G would be useful I'll manually turn it on. Battery life is so much nicer when the radios in the phone aren't constantly fighting for supremacy.
Call it as you will. I leave data off unless I need it for something and when I do use it I only use 3g. Most of the time I'm in a wifi area so I'll just use wifi. Speaking of wifi I leave that turned off also unless I need to use it then I turn that on for the time being and turn it back off when I'm done with it. Other then that I use my phone mainly for texting, and calling when need be. If I'm home I use the home phone to talk, and when I'm at work, I use my cell strictly for text and if you really need me I'll talk to you by office phone. I also leave gps off. I see no reason to leave it on. I tried to post a pic of battery life yesterday but it would not take for some reason.. Like I said. You can call BS all you like. I know what my phone did for the last 30 hrs. Last night I charged it. Downloaded a few apps, and updated some app and played angry birds for awhile last night before I threw it on the charger. Maybe that charge was a fluke. I dunno, but that charge was honestly what I had. Pretty sad to sign up to a forum, look for good info and also try and help out someone else with this phone and give insight and then be called a liar by other folks. Maybe I just won't post anymore. Hope you all enjoy your phones and ROM's. I'll just tend to myself.

Battery usage

Hi all,
First off, thanks in advance for any advice.
Second, if this wrong place or a better thread elsewhere, please let me know.
Now on to the question. My battery drain is quite significant.
Phone has been on for 11h 51min. Charge is down to 45%. Ok I can deal with that (still would prefer better) but my usage is what is baffling me.
It says the screen has used 47% of the battery usage. Screen ontime is 59mins.
Is everyone else seeing usage rates this high?
If it matters, mine is an Optus XXALI5 firmware.
Thanks again.
Pete.

Thanks winwiz.
I did read through that thread but did not think it was the same issue.
Just to confirm, fast dormancy is a screen issue and will minimise my screen battery usage.
Can I apply this fix without rooting phone? Want to keep it stock for a little while.
Sent from my GT-I9305 using xda premium
I think the phone has to be rooted.
Be careful though as I applied the fix as a test and my battery drain went down terribly. This is afaik becuase my network does support FD. Several users have commented in other threads that it is not Network dependant but from my tests it definately is.
Also I found that my phone became quite sluggish and do not remember doing anything else on it at the time. No big deal just re-flashed the rom and it back to normal.
Just sharing my experience and a word of caution.
EDIT: FD is not connected to the screen, it is a way the phone handles the radio in connection with the network by putting it in to a sleep state if there is no activity.

Fast Dormancy is definately Network dependant. So you really need to find out if your network supports it. Because if your network does its better to leave it on
get betterbatterystats and have a look at what's draining your battery. the screen will almost always have the highest usage percentage, it's a hungry beast.
i'm guessing your phone isn't going into deep sleep properly.
install betterbatterystats, charge the phone to 100%, use it normally, and then in betterbatterystats use the dump to file option and attach it here and i (or someone) can take a look at it.
my initial suggestion without seeing BBS would be to try disabling LTE - just use WCDMA only (or GSM only) and see if that helps. LTE is a real battery drainer.

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks
What about your connections? Do you have 3G/wifi enabled at all times?
calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now
Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal
Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone
Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher
Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

but in aps, show good battery state :/
think that I cant trust in it ... and will have to buy a new one
if calibrate doesnt work, hardware faulty, change ur battery mate.

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage
