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 Lifetime

Good Morning folks,
as some of you are already proud owners of a LG2x, I would like to know how the battery lifetime really is. Are you guys satisfied? How intensive are you using your device?
It would be nice, if you can describe what you are running, like wifi, gps and so on... pretty sure you know what to write to give me and the others a clear view on the battery lifetime ;-)
cheers,
Manuel

Yesterday I got the phone.
On very very very hard use it took me about 7 hours for the phone to be 0%. That is kinda good in my eyes.
Today I'm doing normal use, to see how the battery goes.
I withnised 100% tot around 60% went kinda fast, but from 60% till 0% took a while
So stay tuned for the today test.

I got the phone the day before yesterday started charging it. Then in the afternoon it was fully charged and i started to play around with it. It did good but then today i had it fully charged overnight and now - at around 15:00 it dropped below 15%! I hadn't been using it for other than a few calls, a few texts and less than 10 minutes fooling around.
Something is up - i don't know what, but the battery info shows most battery usage was drained due to cell standby and mobile standby...
I don't know what really caused this Other than that i love this phone, i just hope i find the reason for this insane drain soon - i tried rebooting and even installed advanced task killer

Hello, I cant really help much on the battery issue other than to say give it a few more cycles before getting too upset.
The last new battery I had in my iPhone took a week to really settle down.
I would uninstall advanced task killer as I believe it has issues with froyo and is not really needed.

Ok thanks - i think i will then

had the phone 2 days now, and feel like the battery drains fairly fast, had a BB before this and im not used to having to charge everyday. Will se how it goes the next couple of days.

Ok, it seems a lot of people already got their device. Is there someone who could try to unload (by heavy use or something else) and reload the battery again and again to get a feeling of the behavior after some loads?
Thanks!
Update: I have an update from a German guy for you who claims to found out that the service "nvrm_daemon" is the one which consumes the most power. Anyone an idea what it is? The "nv" in the name sounds like nvidia...

nvrm has something to do with the NVIDIA kernel module.

Yes, it seems related to Tegra.
I googled and found this little quote about the offending service on a site dealing with the Toshiba AC100 that also use the Tegra 2 chipset:
it makes suspend, sound and cpu frequency scaling work

Isnt it coz that dual core isnt supported very well in 2.2?
Should be fixed in 2.3.

hey xmoo, how come your always one of the first having such nice devices? if i remember right you had the hd2 pretty fast as well back in okt. 2009.
i wanna have it toooo

48 hours.
Way better than the Nexus One. Not much more I can say.
Most importantly, not much more I will say on battery. It's too subjective and circumstance specific.

I should be clear - I do not mean +48 hours battery, I mean I have used the phone for only 48 hours... This includes charging.
But still, much better than my Nexus One. At the same time with the same apps and usage I have 40% and on my Nexus I would have 15%.
We all still need some days (~1 week) for the battery to settle.

Dunno, I think I got the good connections
I have noticed how longer the device works, the battery gets better.
Today from 8 till 17:00 my batter cme from 100% to 69%.
I mailed, whatsapped and texted a lot and 1 small phone call.

okay in Eindhoven its in stock at a mobilephone shop. i seriously thought about to drive to the shop ... its about 260km from Paderborn
but lg said three days ago the 2x will be available end of next week. so now its up to amazon and its time to say goodbye to htc ... im really curious about the lg 2x
@xmoo thanks for your impressions of battery life. i was a little afraid of power consumption because of the dual core but that sounds fair

hi, 72 hours with the Optimus 2x and i have the same problem with the battery, it drains so fast!! with few use from 7am till 17pm 100%-32% !!! but i think today is better..
here in Antwerp,Belgium there is in stock at pdashop and gsmwijzer
kind regards

hi ~~ just want to ans. the owner of 2X ....
is your handset "Made In Korea" ??

Ok i'm doing a real-life test atm after a few charging cycles.
What did I do/ have I on?
Have I on: Everything (gps, data, wifi (if possible),...)
What did I do: Some gaming, few youtube movies, few short calls, watching mails, some internet browsing, send a few texts.
I'm using the app : Juicedefender in combination with ultimatejuice (this prolonged my battery 2.14x!!!
How long? : Atm i'm using my cell (from full charge) for 44 hours and I still have 39% left! This means that i could get it to run for 3 days on 1 charge!
Note: this is after doing a few cycles, out-of-the-box use gets you the day around!

[3xQ] Battery Consumption

Hello everyone,
I'm running some tests to see the battery consumption on my Galaxy S i9000. I'm using the gingerbread version of darkys ROM.
Firstly, what do you think of the battery life? In this specific test I used the phone in a very light way, made some messages/calls and read few mails.
Secondly, is it normal to have depressions in the battery chart that display less battery than it shows later? How is it computed? Isn't just some logic level of the voltage battery?
Lastly, in the case of buying another battery, is it worthless to be genuine?
Thanks a lot

I have same qestion like you, in the another thread....

Sorry! Obviously I didn't searched properly. Hope someone can clarify us
Is it a gingerbread issue?

Even big batteries will "recover" after heavy use so ur graph is quite normal.
Also be aware that if the battery calibration isnt xorrect then that will lead to weird graphs too. E.g. Losing 1% over 8hrs after flashing a new rom is most likely due to inaccurate battery calibration.

When I install a new rom the battery stats are always deleted? Or it depends?

I also having the same prob...batt consumptions are always the main concern when come to flashing a new rom...Darky's can only last me for 1day with heavy usage and recently flashed to MIUI which can only last for <8hours with the same usage...im not sure why this happen but I am trying with different kernels and see which is the best combination...

I just installed a new gingerbread ROM and guess what.. Using push, wi-fi all the time, gps, 1h youtube video, sms, video call... The battery never ends!! As I'm writing the battery is still 15%. It's amazing the gingerbread in terms of battery consumption. Obviously, something in the other ROM was not right! Guess I'll stick to this battery a little more time.
Btw, the battery stats are pretty normal, no depressions..

[Q] Battery Issue

I've been reading a lot on these forums, and no one has seemed to address ways to improve battery life on the LG Revolution. I just got this phone a week ago and I've been averaging 13 to 14 hours of battery life with moderate to heavy use (applications, e-mail, texting, etc...).
Anyone have any tips or tricks to improve the battery life besides rooting it?
Is it worth rooting it now with Gingerbread rumored on the way?
Thank you all in advance.

personally..GB isnt available with Verizon yet..I would look for any leaks or anything that isnt officially supported..unless you wanna try it..turn BT off..use wifi when you can..turn screen brightness to 50 on the bar..try to look for battery saving apps on the marketplace..just a thought

I just got the Decrapified Rom on mine today, and am seeing some decently better battery life.(i used to get ~12hours anyway with some heavy usage)
Also...when I rooted and customized SetCPU a bit I saw much better battery life. I was able to clock down the CPU when the screens off, or when the battery is low, etc.
Just some thoughts for you

This helps battery life? I always thought wifi drained battery. But your saying wifi drains less battery than 4G? What about 3G?

Check your apps as well. I was watching my battery drop a percentage in literally minutes. I thought it was just the phone, and that I had to live with it, but in my case it was Go Weather!!
This app is EXTREMELY bad - drains battery insanely, and even when you configure it, it keeps popping back up in the running apps and goes to town draining your battery.
Apps like that can make a somewhat average battery life turn into an insanely bad situation.

13 to 14 hours with moderate to heavy use???
I'm lucky to get 10 hours without any use. I let it sit on a table overnight, and the next morning it was down to 28%.

What's the best setup for optimal battery life?

I only really use my z1 for Spotify, LINE, reddit and Facebook. Currently the battery life isn't so great as it needs charged during the day..
What's the best rom/firmware etc to flash which will give me the best battery performance?
I've not been on xda for quite some time so I'm a bit out of the loop,I did some looking but couldn't find a definitive answer.
Cheers!

I'm on stock but rooted lollipop, with Stamina mode and Greenify helping each other out. Also I underclock down to 1GHz but I'm not quite sure if it helps.
On all my past devices running the stock firmware almost always makes the most out of your battery.

I am on stock firmware already, I got greenify an the donate version but after testing it yesterday it didn't seem to make much difference.
Perhaps this battery is just dying cheers for the advice though

Sorry for late reply, didn't get notified.

I think that's normal pretty normal battery if you use Spotify+LINE+reddit+Facebook with 2 out of 4 signal o__o
Well the thing is that when you play music on spotify, your phone cannot sleep.
You should try to get a better signal/reception of wi-fi and cellular. I have read that these without good signal could cause battery drain, as you see, cell standby at 9%. Sorry I don't know how to improve those but :/ yeah..
Maybe try "Stamina Mode" if you didn't activate it (It should have a + logo next to the battery when activated)?
Lower your brightness if you can, that's the biggest drain!
At last, for a rom suggestion,I don't have because I'm stuck on stock roms ._. , maybe try some custom roms when you have free time

Yeah it's not too bad I guess, I just use it more than I realise. Already running mxrom, I've found stamina mode doesn't make much difference.
