Battery drains quickly

Not sure if this is a problem with the captivate (Rogers I897) or if it's just a select few, but I noticed last night despite the usb charger being plugged in overnight, once the battery reported full, it stopped charging.
So basically, I got home from work, plugged in my captivate because the battery was rather low (only takes 24 hours of maybe 30 mins to 1h of actual usage before I get below 40%), and it took 4-5 hours to charge completely. When I unplugged it in the morning though, it was already down to 64% with just being idle all night.
So is this normal or should I ask for a replacement battery or something?

There are a lot of posts around here about batterirs dying quickly, and "charge death", but I'm not really sure whats going on with your phone. All I can suggest is that you make sure that you close all apps and stuff before letting it idle, and just see how that goes. I suppose you could just have a bad battery. Are you on a custom ROM or stock? I had problems with battery life when I first flashed to a custom rom, but since then I've switched to serendipity 4.3, I have it undervolted, I keep an eye out with a task manager, and my phone has no problems lasting all day, even while texting a good amount/using it for searches and stuff.

What ROM are you running?
Did you have GPS/Bluetooth/Wireless left on?
There are known issues with certain builds of ROM's causing this issue. If your on a stock ROM and still having this issue? I would take it in to possibly have it warrantied out or at least have the battery replaced.
I haven't ever had an issue with my phone losing a charge while plugged in.

Yeah, stock ROM. I haven't installed any additional task managers, but I usually open it up and kill all tasks when I'm finished with them.
I do keep bluetooth and GPS off at all times, but I leave wifi on overnight because I didn't think the battery would stop charging entirely once it was full. I've only had the phone a week so I could get it replaced, I just wanted to investigate it a bit to see if it's a common issue or not before I did that.

Settings --> Mobile and Network --> Wifi Settings --> Advanced (soft key) --> When screen turns off
This would turn off wifi after 15 mins of inactivity. This would help save ur battery.
And yes, charge does get cut off when left for extended times, but not right after it says charge full.

Recalibrate your battery/battery stats. This is my method, there are many others though:
1. Charge the phone with the phone ON, until the phone indicates full battery
2. Unplug the charger, replug, continue charging until full battery again (I repeat this 2-3 times)
3. Turn off phone, charge until full battery
4. Unplug the charger, replug, continue charing until full battery again (Again, I repeat 2-3 times)
5. Turn on the phone, let the phone charge yet again.
6. Boot into Android Recovery, delete battery stats (Advance -> Wipe Battery Stats)

Cool, I'll try this, thanks!
By default, wifi does get turned off when the screen goes dark and I haven't changed it.
I've also been tring to flash to a new ROM (been trying Android 2.2), but Kies won't load my phone). I think I'll research other methods when I have time.

In most custom 9000 based ROMs, wifi is set to "never off" by default.

Ah! Didn't know that. I'm extremely new to this whole smartphone thing (just got mine a week ago) and haven't actually done any hardcore (stuff that requires flashing and whatnot) customizing yet.

If u r not heavy on data and use it for things like mails and chats, and esp when in an area with no proper 3G coverage, u can switch to EDGE and get out of 3G. 3G sucks more battery compared to EDGE.

So I wasn't able to complete all the steps to kind of fix the battery problem, but I plugged it in to almost 100% (I think it was like 98% or something, I had to go out so I had to unplug it), but when I got back I plugged it in again and let it charge overnight. This morning however, it was still at 100%, and now, about 8.5 hours later, it's only at 73% so I think maybe it just had to normalize it.

Give it some time to normalize. And charge showing 98% when unplugged at 100% is normal.
And yes, seeing 60% battery left after an hour of calls and tasks involving an hour plus of display on after a day's work, apart from push emails, etc (~14 hours standby) isn't so new anymore to me.
Stop watching the battery so closely for about a week and u'll be all set

I was on darkys 8.1 rom with jk4 modem, calibrated the battery one time and I went 18 hours. Starting from 98%
6 hours were phone calls, 1.5 hours of text messaging. 2 hours of power amp . The rest was pretty much just standby/idle time.
Though, I don't get that anymore though.. Jk4 has gone to **** for me. I used to get full signal majority of the time, and for places where other people go no bars, I got one or two. Now its pretty horrible it makes me sad ;(

[Q] Battery Problem??

I dunno whether it is a battery problem or what but I got a brand new battery
coz the last battery was too bad but the new battery also sucks.
I was wondering if it was cause of the ROM and kernel so
I switched to stock rom for trial purpose and still I got juz like barely 7 hours of juice....
with juz some files thru bluetooth and half an hour or so of texting....
so what could be causing the problem?
Here's the battery stats...

I'm not really an expert on this... but I'll try!
First, data - depending on how often your apps that use data refresh, it may be killing your battery because they are always updating in the background
Next, apps - depending on how many are open, and trying to retrieve info or a responce, this may be killing your battery life
Another, backlight brightness - I would say half brightness looks almost the same as full brightness, so turn that down too. Another thing you can do is make sure that your phone times out so the screen is always on and sucking the life out of your battery
Plus, bluetooth and wifi - turn those off when you aren't using them! They turn on in a couple of seconds so there is no use in just leaving them on and draining your battery.
Lastly, I dunno what "kik" is (the app running in the corner of the status bar) but it may be using battery too (probably not because it isn't in the list of the battery use so I don't think that's it.
Anyways, in short, possibly shut off the data if you don't always use it (you don't have to tho ), go into the settings of apps, and get the refresh rate at a longer period of time (so they aren't always using data), kill any open apps if you can with an app manager, turn down the brightness of backlight, change the time it takes to shut off the backlight, and shut off the bluetooth and wifi when you aren't using it.
Unfortunatley the battery life on the Ace is far from the best, if anything it's terrible, but other than that I have very few issues with the phone.
Well... That's my two cents. Hopefully it helps, but if not, search around on the forums and see if you can find any other solutions. :fingers-crossed: I'm not the expert, but I'm trying to throw ideas out there. Good luck

Running background processes is a major battery kill. I used to get 12h+ on 3G with Stocklite V6. Never used heavy apps though. Just Textplus, Opera Mini to check fb sometimes and WhatsApp whenever someone talked to me. Light usage.
How much the battery lasts depends on the user completely.

First of all thnx for taking this much time out....
It's rlly helpful...
but
1. My data usage is barely 10 mb per day....
and no wifi and mearge usage of bluetooth....
2. Background apps;
only adw and one or two others...
and Kik is juz like whatsapp, a messaging app....
and it's quite lightweight, been using it since uite some time...
3. Backlight is at an always 25% and screen timeout 30 secs....
so juz wanna know if there's a possibility of some hardware fault......
coz I've tried most things possible to take out the software fault if any....

Wait, i just forgot!...
I get this too sometimes, but what might help is if you reset your battery stats! I have to do this too because I found that after a half an hour after unplugging my phone with no use I lost 10% battery life, for no apparant reason. Search in the Play Store "BatteryCalibration". All you have to do is charge your phone to 100%, and tap the button . You usually have to do this after flashing a new ROM, because you might not flash it at 100% battery life and the stats go from there. So I would say, try it and see what happens.
Now... If not... The only other suggestion I have is if you find a battery booster app such as "Juice Defender" from the Play Store. I tried using it, but didn't see a huge difference (I don't have data, so I just keep it off), probably because I barely use my phone. I've also heard some thing about a script called "v6 Super Charger" (I've only heard of it, please search it if you want to know more because I sure don't ). Aparantly it boosts battery as well, but no promises haha.
If you are really desperate for better battery life, I would say switch to 2g service in the settings. Other than that.... I'm out for now
Hopefully this might help you out as well, but other than that the Ace is not well known for a good battery. But that's a mid range phone for you (but the Ace ain't no slouch either)
Anyway, goodluck!

Ok, so after looking around a little, I found a very interesting thread about Lithium-Ion batteries! Really cool and really worth the read! I learned quite a bit. Hopefully this answers any additional questions that I wasn't able to answer!

Try also eliminating any widgets or live wallpapers that you may have running. These might keep the processor running at a higher speed then neccessary, but no promises.... Plus I already mentioned closing apps you don't need (so this is pretty much the same woops) and you might have done it already.
The biggest thing to remeber is that you have to sacrifice performance for the best battery life. This may go as far as underclocking your maximum CPU speed, but this might cause some lagging especially at the startup. I think that this should be a last resort to be honest, because you still want to use a phone, and not a laggy device that you are trying to conserve as much battery as possible.
I also heard something about the motherboard possibly having a hardware fault in it causing excess discharge... But... I will need to do a little more searching to see if I can figure this out for you!
The other possiblity is that you get a power bank... But that just adds to what you have to pack around, so this is probably another last resort, but it's all up to you.

Absolutely sudden battery drain-GingerDX

Hello Guys, I'm using GingerDX from months and lately I started getting a strange problem- I go to bed with fully charged phone and in the morning the phone is switched off and when I turn it on it has only 1% battery left. This happened only 3 times-always through the night-one of the times I was even on airplane mode. Beside this- the battery acts pretty normal- 2 to 3 days.I took every popular battery saving measure, by the way and the internet traffic is always off when I don't need it.What this could be?

It happen on all roms,that battery goes down very fast. Like 2% in minute. If you see that,just reboot your phone and problem is solved + stop running services!

Thanks, but I can't see that, since it happens while I'm sleeping.I also have very few services running almost all of the time.And why isn't this happening all the time- I'm using the phone in the same conditions and settings all the time?

if its at 1% and the phone continue work then you might need calibration, but if you are telling that its shut down then might be hardware problem( of your battery)...
but you dont loose anything to go back at stock and see if the problem resist....

It shuts down, because the battery got empty at some moment-I guess this is normal.Then it stays switched off till I awake and notice it,let's say few hours ,and then when I am switching it on- I guess it has enough power just to turn it self on, after which I'm putting in on the charger.And yes- battery is calibrated last time I changed the Rom.

[Q] Galaxy S Plus battery swelling?

Dear fellow enthusiasts,
since a couple of days, I'm experiencing sudden device crashes when I'm using it for network related activities, mostly over the 3G network (for example, I'm typing out a message on the Facebook app, and the phone goes into boot loop or simply "shuts down"). I had only recently upgraded to the 4th beta build for the Cyanogenmod 9, hosted here on XDA , so I suspected it would be related to this. However, upon reinstalling both the previous version and the new mod from absolute scratch, the issues remained the same.
I had noticed that after each crash, the battery charge displayed as very low (2-6%), whereas I'm certain the charge should be much higher. So I thought it might be some sort of corrupt battery-cache issue or something.
However, and here's my actual question, I just now noticed that my I9001 battery is slightly bulged, on both ends. This bulge starts just above the white printed SAMSUNG lettering, and it ends just bellow the QR code. I can't for the life of me remember if or not this is normal, so could someone please confirm this for me?
And while we're at it, could a faulty battery affect my performance as such (making my phone crash etc)?
Thank you very much in advance for any help or information anyone could give me.

I confirm, battery is slightly bulged in those places but it looks like a production "thing" to me (I hope I understood what you mean), no need to worry, I guess. Looks like corrupted battery stats, try to wipe it via recovery (phone fully charged, plugged in - then wipe battery stats). After that, i recommend one or two full battery discharge - charge cycles. I've noticed hovever, that after each full factory reset I have for about 20% better battery drain, than after flashing many ROMs, kernels and updates (cache and dalvik cache wipe only), my battery drain is getting pretty annoying. Try a full factory reset, if wiping battery stats didn't work.

I received my new battery last night, I went for an Akku Powercell of 1800mAh. Charged overnight, been using it all day, no problems whatsoever to be found.
Thanks again for the assistance!

Swollen battery = defective!
I'm sorry but I've encountered this as well in the past. Normally working phone with sudden shut downs and huge drops in battery charge. It took me a long time to convince me that the battery was defective. So maybe this would save you guys some time in finding this out!

In general healthy batteries DO NOT swell. Buy a new one before it explodes or starts leaking...

Hey all, just because people keep on posting, the battery was indeed defective, the roms were absolutely fine and the new battery is performing marvellously!
Thanks again for all the input !

I have the exact same problem with my sgs i9000-gt.
My phone turn off itself ( no restarts, its a complete shutdown ).
First, I thought i might be a problem of GB 2.3.6 rom i was using, so i updated to latest cm10 but the problem persists.
If you restart the phone after the shutdown than i shuts down within a minute again.
Also the battery drain is pretty fast. I notice the same bulges on the battery as reported in this post.
I did the battery calibration thing as some people suggested, but that does not solves the problem. However, it got rid of the fast changes in battery status which was happening before. Like when you restart after shutdown at 80% battery status, it will show like 2% battery left and after few minutes of charging it would boost back to 80-90%.
But still the battery drain is pretty fast. It discharges from 98% (i cannot get to 100% charge, 98% is highest) to 50 % within an hour, just idling.
And when i am around 40% or so and if i recieve some message and try to open a app it shuts down again.
I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.

problems fixed so far after replacing the battery

I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.

I flashed back to stock samsung rom ( from the value pack) and the problem persisted.
today my new battery arrived and all the forementioned problem seems to be gone with the new battery, my phone seems to be working fine for last 5 hrs without any restarts or crazy battery drain. will test the same with custom roms again. As of now it only seems that problem was the battery.
Cheers.
thanks to the forum and developers

[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
