Suddenly bad battery life = battery gone bad?

Basically, a few weeks ago I flashed assonance 5.0 and my standby battery life was terrible. The battery would die by the time I got out of school which is around 7-8 hours of standby time.
So hoping to solve this problem. I flashed the captivate version of doc's rom and I have the exact same battery life. I have recalibrated the battery many times as well.
Sooo, do you think my battery has gone bad?
And if so, any good places where I could get a spare?

Many have posted eBay has some good deals.
I still suspect that many of these phones were shipped with crap batteries hence the differences with people using the same roms having much different battery life.

Well the thing is that my battery life wasn't terrible before. Or not this bad at least :x

Have you at least tried reflashing to stock to see if the problem is with the roms or with your battery?

Not for an extended period... but the thing is I read through some of the rom threads. And if it was the rom people would be complaining about battery life, but no one is :/
In fact, it is quite the opposite...

kernel related or bad battery!!!!

Well i am using Glitterball's latest kernel before Firebird. Or the stock kernel that came with the Doc's Captivate Rom 7.0
Either way, there has been a huge drop in battery life and I do not think it is kernel related, because on the Assonance 5.0 rom, i was running Setiron's 1.4.7 kernel with the exact same problems with battery life :'(

This is highly dependent on how you have your settings on your phone.
1) Wi-Fi constantly looking for an active network connection? At least have it go to sleep when the phone goes on standby. I only turn mine on at home or otherwise need and have access to it. Otherwise its off.
2) GPS running all the time? Personally, I rarely ever need to use it, but it runs great when I do.
3) Display at recommended brightness or higher? Recommended or less is best as far as saving battery power. I like mine all the way down. Don't need/want it any brighter.
I even tend to use only darker wallpapers as bright and lighter colors pull more power on AMOLED screens. This makes a little bit of difference. How much I don't know, but I do know that it does. Sometimes the above settings like to change on you. It's a good idea to check 'em once in a while.
While it's usually always around 60% full when I go to bed, I still charge my cell every night.
I have found that the speedmod kernel is real good for conserving battery power. Not downing other kernels as they're all real good. Speedmod handles battery consumption better in my experience.
Have you installed any new software that might be accessing the network checking for updates/feeds, etc?

1)I always had my Wifi sleep policy on never. So its not what is affecting the battery life
2) Never have GPS on unless i need it. Heck, when i need it, it never works.
3) nothing that i didnt have before.
Basically, I haven't changed anything to cause the decrease in battery life.

Your two biggest drains on battery are WiFi (especially when consistently seeking - any new access points where you leave it on standby all day?) and your display. Could it be your battery? Sure. Go exchange it at AT&T. They shouldn't have a problem exchanging it for you

Well the thing is. I have never had this battery life with my Wifi settings left untouched. So yeah, i will probably get a new battery from AT&T tomorrow and report back if it was the battery or not :]

give this thread a quick read, its more based around 2.2.1 roms but you could find some good information

Battery Probs..

Battery kept saying 100, but as soon as it was unplugged instantly went to 99.
So i used odin and did the whole nine and charged phone while on had to charge three times back to back and and then it stayed at 100 even after unplugged give it a try..... Hope it works for y'all too!

Where you running a 2.2.1 rom? That battery reating us a known issue

Long way to go for 1%.

lol, some has to have it perfect. ...and yes I'm guilty of that too

Well, if you consider the percentage as being a visual respresentation of the battery's voltage along with a bit of math, then as soon as you remove the charge power, the voltage drops.
It's really nothing like the fuel gauge in your car. Don't get too fixated on it because it's not a very accurate representation of "how charged" the battery is especially at the top, but the 100 is so much better than the stock 10 or so icons... which was more out of sight out of mind.

Yeah I was on 2.2.1. So that drains the batt a little quicker?
Sorry to sound stupid. Still new to all this.

In 2.2.1 there's an issue discussed in the Perception thread where the system apps sync constantly.
Go to Settings->Applications->Samsung Apps and turn it OFF.

An interesting read for you may be the http://forum.xda-developers.com/showthread.php?t=806211&highlight=battery+drain thread. I found this useful when I discovered the issue myself.

In 2.2.1, it's a known issue that battery will jump from 100%->98% almost immediately after being unplugged. According to the kernel gods, and if I understand correctly, it's entirely cosmetic, and is just a change in Samsung's reporting functions. So long as it doesn't continue dropping at that rate, I think you're fine.

Thanks for the info.

[Q] What to do Against battery drain?

I now have one week to the Nexus One bought secondhand. It suits me perfectly stand alone I have a little trouble with the battery life of the phone. Morning when the phone is 100% and I come out of school (14:30 hours) the battery is still around 20%. I find this a bit short. Ok, I'll use him at school (bit Internet, twitter refreshes every 9 minutes)
There is an automatic task killer, and that helps a bit but I think there are about 80% after 8 hours battery life is a bit much. Me internet is also constantly and I really like to keep.
The battery is probably not because I've got 2 batteries and they both give the same result.
Anyone have any idea what I can do?
I've been a bit inet searched but not really found anything. I did see somewhere a separate battery behind the phone, but I'm not waiting because that makes him a bit heavier and uglier.

10% per hour is pretty poor battery life. Are you running stock Android? 3rd party firmwares can give you much better battery life (the latest versions of CyanogenMod are using less than 1% per hour when fully idle).
But there are things you can check. Have you looked in Settings -> About phone -> Battery usage? If you are using Gingerbread and you look at the graph, if there is a solid line (or mostly solid) next to the "awake" portion, it means that your phone isn't properly entering its low powered state. Download spare parts from the market and check out partial wake usage under the battery history section of that app.

Please post your screen on time value from the battery menu so we can see how long your screen is on.

I would say to go and disable background data. Disabling this will definitely improve your battery life. Of course, you aren't going to get you twitter updates but aside from that, the battery life should improve.

While it is true that battery life would improve if Background Data was disabled (or limited via a program like Juice Defender), it doesn't take into account his actual problem. Unless it is a ton of apps constantly downloading that is keeping his battery usage in the toilet, this will only yield a slight improvement. I believe the cause is is an app (or apps) that prevent his phone from entering the low powered sleep state.
I don't know what stock Android gets from completely idle use (haven't run it since July last year), but a basic CyanogenMod install would sip between 1-2% per hour with the latest stable and the latest nightlies, some are reporting 1% every 2-3 hours when the phone is left alone (due to a fix that lets the microphones go into a deep sleep state).

Twitter refreshing every 9 minutes can not be helping, that said I doubt that's your entire issue but reducing the refresh rate should help quite a bit.

If you bought it used, it could be a bum battery. Not sure i know what apps work best to find out that info. Anybody?

The battery app in my sig is the only one that reads the chip inside your battery to tell if it's legit or not, what the battery age is, etc. Needs root to work though.

You can also get Battery Left from the Marketplace and when it gets calibrated it gives you a time until death number and some other features.

Your Android OS is draining your battery waaay too much. Does MIUI still have the Android OS bug? Reboot into recovery and clear cache and davlik cache, and continue monitoring the Android OS. It should be less than 10%.

Hi.
Thanks for the advice.
I did what u said. battery usage android os 31% and sys 29% but when i change for unplugged usage it shows sys 18% OS 9%. The previous is the total usage. Do u think its fine?

Hi, I'm using MIUI Mint Berry Edition 1.10.28 and the battery is very good, perhaps you should give it a try. Another trick is to delete google talk if you don't use it

???
you think google talk drein battery?realy?

I believe the default options in Google Talk is to have it login automatically. I never used it before, but when I first got an i9000 I remember going through apps I didn't use, and noticed that Google Talk—even though I never, ever used it—was signing it and staying signed in the entire time I had my phone. I quickly got rid of it (although you could probably just turn off the automitic login).

hi guys!
THX for the ideas but I got one yesterday from another forum. I just wiped in recovery mode the darwick memory or what and now its perfect. I charged the battery fully yesterday at 17:55. Was playing and using wifi ,still have around 20%.
Sent from my GT-I9000 using Tapatalk

wipe dalvik , wipe cash , format
then put miui on your sdcard and flash it
after that , clear dalvik cash and wipe cash partition again
calibrate your battery using battery calibration app ,
reboot.
the problem should be solved , but i must tell you , miui is battery HUNGRY and u will NOT get more than 3-4 hours screen time

You could try Juicedefender. That should buy you some time!

I find apps like this normally do the opposite, Just another service eating up CPU power. Also don't judge a ROM's battery from the 1st charge. Calibrate and the battery tends to settle.. Though IMO Cm7 ftw, 2 days usage from it

I sort of agree, but it depends on how much battery the app is saving you. Sure, it takes some CPU usage to be able to work, but if it's saving you 5x as much battery by doing so, then it's obviously beneficial. Lots of people swear by Juice Defender, so it must work as such.

Hello ppls. I've seen a lot of posts about high battery drain. I am wondering about my battery life.
So, i unplugged my SGS at 10am,said 100% when i unplugged it dropped to 96% (i read its normal, the protection against overcharge), left at 10.30 listened to 1h of music,15m of just twiking,writing 1 sms,at 13:30 already 59%
Faze II: 15m on facebook via wifi,wrote 5 sms,played 10 mins- 39%
III 1h music +10m gaming+ 15m twiking, at 8pm 20%.
IV about 5m of audio recording, and probabably about 10m of gaming->10% at 12:30 am next day.
No 3g, wifi only when using internet apps, using juice defender ultimate.
I'm using Darky's rom 10.1 . I bought the phone with this rom, and i can't flash a new one cause i can't connect it to my pc in anyway(same on other pc's too)
To the battery : Is this normal? Thx

Battery Life stinks and phone gets hot

My battery life is pretty terrible. Running stock, power saver, and Snapdragon battery guru. I have to charge the phone 2-3 times a day. I use in moderately to light through the day. At night, it will drain almost completely while I'm asleep. I had a Nexus 4 before and battery life was way better than this, same location, same apps, etc. I don't feel like I should need to turn data and wi-fi off to get more than 6 hours of virtually idle phone life from this device. Is this typical?
I find the phone is hot a lot too, when I am not even using it.

Please try to find out what causes this drain with the following app and post results after 1 unloading cycle

I downloaded it. Shut phone off and letting it charge, then going to see how fast it drains. To boot, its been on the charger for 2 hours and it has gone from 9% to 62%. Something must be wrong.

With stock my phone battery life sucked as well.that's why I rooted it and running a sense 5 Rom.. and it's so smooth I have my kernel UC to less than one gig speed and it still move fast without the overheat

Definitely not typical...
I'm fully stock and not rooted. If I dont touch my phone it can last over 24 hours with data on (noticed this one weekend when I was too busy to play with the phone).
I use the Battery Widget Reborn app and it says a "Fully charged battery usually lasts: 18 hours 8 minutes" for me.
Sounds like theres definitely some kind of app in the background thats draining your battery and making your phone hot.

This is pretty typical battery life for me with data always switched on on a rooted stock 4.2.2 rom and was also pretty much identical on an unrooted stock 4.1.2 rom.
The main thing that saves me a ton of battery life is disabling apps that I don't use. By far and away the Facebook app is a massive culprit for killing battery life.
I'm very interested to see the gsam results when you post them.

Well it's a definite improvement over the sort of battery life you were describing before. There are always ways of improving battery life but as has been said many times before it's all a case of where and how you use your phone that will be the main factor.
