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 :]

[Q] Help With Kernel Choice

Fellows, i just bought my SGS a few days ago , and the moment i bought it i upgraded it to Arabic stock froyo and a friend recommended to use stock+Voodoo-5.0.3-Froyo-GT-I9000-XXJPX kernel
i used it , got 1424 on quadrant and it was very nice in performance but i got strange battery life, it didn't last for more than 10 hours with everything switched off.
so i returned back to stock froyo (pda I9000 jpjpf, phone I9000 jxjpd) and now i got nearly 24 hours of battery life.
what confuses me is that, during using voodoo, the battery was during the first 2 charging cycles of its life, and when i returned to stock froyo , it got into the 3rd charging cycle, and now its moving on towards getting better in battery life.
so my question is , do you think that the kernel was responsible for this strange battery life, or the battery was warming up and needed to be charged and discharged to get into its performance.
also , any suggestions about kernel for battery life with good performance, personally i did like the phone when it was on voodoo @ 1424 on quadrant
please help , and sorry for explaining a lot
thanks

Quadrant is a false test when it comes to use and responsive phone .

thanks for your reply
i did like the phone when it was on vodoo, regardless of quadrent
my aim is to know about battery life

Read the battery faqs and posts on this very page .
But battery life is very very variable .
jje

i am afraid that battery faq does not have an answer to my question
i want to know if the change in kernel is responsible for that strange battery condition
or it was that the battery was at its first charge and discharge cycle?

Going from 10 to 24h of battery life, it could be a battery stats problem, it happens when changing ROMs.
But to answer your question, I dont think voodoo is responsible for the battery drain. Personally I use SpeedMod (without lagfix) with Froyo JS3 and it works really well battery-wise and performance-wise.

you don't think that voodoo is responsible ,
well that's some good news for me actually cuz i did like my phone's performance when it was using voodoo's kernel
thanks for sugesting speedmod , will read about it for sometime and see if i dare to take this action again , cuz battery life is a must for me due to my work
i can't stand the phone that needs more than one charge per day
any more ideas everyone?

I also use speedmod and battery life is excellent. Even with heavy use I get over 24 hours no problem. If I was to use it just as a phone I think I could get 3 days use.
And yes, I agree that your battery stats were probably a little messed up and should settle after a few days of use.

I'm using SpeedMod with SeaARMS' JL2 ROM and the battery lasts much longer. If you have a Galaxy S on Bell Mobility it's the best option to keep the 850Mhz radio working.

galaxy s battery question again! maybe software issue!

Specs are as follows followed by the issue. . .
i9000
jvt djbrom 1.13 latest
semaphore kernel
ext4 partitioned
phone runs excellent!!
in battery usage the graph is practically flat when the screen is off but with the screen on and with the phone in use the line drops very rapidly giving me very poor battery life! what i'm thinking is it must have something to do with the display or another hardware being run and using so much juice its beyond a joke! what is the specific problem with the display using so much battery? Screen brightness is at its minimum so it must be the actual graphics/drivers/hardware/voltage giving the drain! how can this be reduced? something needs doing about this but what??

Can you post the graph screenshot?
Along with apps usage...

[Q] Are the battery drain issues with ICS fixed yet?

Hey there,
In case you can't tell, I'm a newbie.
Anyways, I'm currently using a 6-yo HTC Dopod Pro and I've finally decided to get a new phone.
I really want to get a Galaxy Note but I hear that the Note has a relatively short battery life.
I also heard that ICS for the Note causes the battery to drain even quicker.
Have these issues been fixed yet?
Cheers.

What you have heard is misinformation. A bad installation of ICS, rogue apps and weird settings are the cause of people having battery issues with ICS.
The Note has one of the best battery lifes among all android phones.

Note has excellent battery life. I have the LQ2 ICS, and I have no weird battery drain, wakelocks or any other probs

Just disable some draining apps on ICS.
Don't forget the huge power of note battery( 2500mAh)

I heard the battery life was pretty good whilst on GB but as soon as people upgrade to ICS, the life was substantially lower.

The battery drain "problem" of the GNote is like troubles with your Windows computer (IMHO): The more you fumble, worse it gets. Use it as it was designed and you'll be a happy person.
I have a GNote for a few months, it was Full Stock under GB and now is Full Stock under ICS. I use it moderately (2nd phone) and could easily manage 36 hours.
I pick it of the charger ~5h30, 6h00 in the morning and find it at 60~70% when I get home about 12 hours later (30~45 minutes talk time, not much else). I than read my favorite blogs and news papers that runs it down to 30-40% (reading takes about 1,5 hours).
When I go to bed it's never lower than 27-30%
The only problem I have is that it sometimes doesn't go in Deep Sleep and that I solve through a systematical reboot in the morning (of the charger).
As always (even people) the GNote is as good as you treat it

Hey Little Vince
Welcome to XDA!
I have had Note for over 6 months (bought from UK to Brissy) Been on ICS only last eight days or so - and I can report that the battery life is slightly better than GB. Speed is better too - not as much lag.
I have used Blackberry/Axim/Palm before and always got into the habit of charging overnight so anything longer than 24 hours doesnt really matter.
Please don't let others put you off a wonderful phone. It is so versatile.
PS - it always takes a few battery cycles (e.g. three or four days) before you get accurate info. I have had quick battery drain for a few hours after updating Kernel but it always settles down.

I found my battery life was quite poor at first but it has improved after a few charging cycles. Also, I had a lot of syncing processes running (some duplicating others). Killing some of those also helped.

Never had an issue with batt drain, either on gb or ics... I think the latter is a bit better. I leave gps, wifi and 3g on all the time, and am a relatively heavy user... really haven't tweaked anything for batt life, other than removing some bloat.

OP, it would probably help if you told us what you would consider to be decent battery life. That way, people will be able to tell you if it is possible.
As for me, I'm on CM9 and have never tried stock ICS. I can confirm that battery life was better on GB, but CM9 still gets me through the day on fairly frequent use.
Usually fully charged when I get up in the morning (6am), and down to about 20-30% when I charge it at night before bed. This will normally include roughly 3-4 hours screen time from watching movies on the train and internet browsing throughout the day.

Same here no battery problem. I'm using DXLP9 firmware.

Nah battery drain is a real issue with ICS. It's too documented to be denied. Doesn't matter what I think is good battery life, but relatively with GB, it was 20-30% for about 12 hours of use (wife doesn't use it much) and after ICS, it's -110%. Hmm.. I meant for the 12 hours, it needs a charge and then some. And that's crazy since my wife really doesn't use it much.
Anyhow, this completely fixed it for me. Looks like there's a few bugs that you can come across if you have battery drain with ICS. Check the full thread for more details...
http://forum.xda-developers.com/showpost.php?p=25980444&postcount=2
UPDATE: ok no. Still no real solution for fixing this after trying many over lots of days. AFAIK, kernal problem that Samsung needs to fix. And please do fix!!

As I see it from the times from BBS the problem of the drain is at standby mode where the battery for the start of locking and outing on sleep it eats slot of battery till it reaches the 1% every 1 hour and 45 minutes like it was on lc1 stock, even I had on GB 2 hours 45min for 1%, it starts with 1% for 30 minutes then 45 min 1 hour and so on till it reaches the max of it.
The use with screen on is the same 25% for 1 hour and 20-30 min screen on time with low brightness, as it was with GB. On GB I had 5h30m screen on with 10-14% battery left.
So the issue for me at least, is the standby aka sleep mode.
Sent from my GT-N7000 using Tapatalk 2

to the OP, yes battery drain is a documented issue on ICS, with the wake locks and rogue apps (for the unlucky few.. myself included)
i was on rooted stock GB and i used to have a good 72hrs of standby time for the note especially on the weekend when it is rarely used and maybe a good 48hrs on a weekday with average usage (about an hour's call, moderate surfing, facebook etc)
during days when i travel a lot i can be surfing and listening to music and doing calls for the better part of the day and the note still lasts a day with about 20% juice left by 7-8pm
however after I upgraded to ICS LP9, my battery couldn't even last me for a day without getting a few hours of charge from my laptop, i was on stock ICS for 2 weeks and did a lot of fine tuning just to optimize the battery life and ensure the phone goes into deep sleep and still not sufficient. the thing that blew it for me was when i noticed that my note started running at 1000mhz only and not any lower (even when charging - take note i was on unrooted ICS).. so decided that ICS with all its hype wasn't polished enough yet and was not worth it for me and went back to my stock rooted GB LC2
now i'm a happy camper.. note sleeps like a baby when it is supposed to and runs smoothly when called upon
so to answer your question (sorry about the long story) yes you can enjoy great battery life on note be it GB or ICS but you won't know until you get one for yourself.. and like what the other posters said the note is such a beast of a phone that you will not look into another phone again once you get one be it on GB or ICS

I absolutely would not recommend the G Note until there is another ICS update issued - unless you want to stick to GB (in which case I would definitely recommend).
Apart from the deep sleep problem, which for me anyway, cannot be resolved, I've had stability issues, overheating and it even pulls restarts without warning.
The only battery fixes that have kind of worked for me (and they still don't get me anywhere near the battery life I was getting with GB) involved me following a 5 step programme every time I charge my phone, which is frankly unacceptable.
FYI - I've had the note since December and it's running stock everything.
The Note is an amazing phone, but ICS has rendered mine not fit for purpose.

The sad thing is samsungs and android capabilities in finding the culprits. Fancy native battery charts which dont help much, if any in analyzing.
Only best case is to check deep sleep(cpuspy) , and if deep sleep is low check partial wakelocks in betterbatterystats.
Then you can find a lot of the culprits
Good thing the XDA community picks up where Samsung/google drop the ball.

To the OP. My Note on gingerbread had wonderful battery life 16+ hrs. After the ICS LPY update my note dies after 5 hours. To all the naysayers saying there are no issues with battery life on ICS, give me a break. Just google how many note and galaxy SII users on ICS are having battery drain issues.

I get exactly the same battery life on ics that I did on gb, the battery drain people are having has nothing to do with ics. It will be apps causing the issues. Im running exactly the same apps as I was before and its exactly the same battery.

mmm.... No.... The same apps, even after a factory reset and reinstalling apps I STILL had the drain. You say it's apps that aren't optimized? That could be true... but then again, I guess it must be a VERY VERY common app that's causing this because most everyone says they've experienced a decrease in battery life.

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.
