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] 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.

[Q] Batterylife issue, can't find any threads that help

There's not a single thread out there that has helped me with my damn battery life that I've been able to find. I'm sick of hearing, "did you search first?" Yes, I searched first. I didn't find anything that helped, that's why I made a new thread.
Anyways, I've tried apps, widgets, calibrating, deleting batterystats.bin, flashing different roms, kernels, modems, and even a new battery. Not a single thing has made my phone last through the day, and it's getting to the point where I'm about to flash back to stock, and forget about it. I need to be able to use it when I need it, not put it back in my pocket because I'm afraid of draining the battery. Honestly I'm not sure if the battery issue is rom related, so If that doesn't work, I may just get a different phone. I need to not have to charge my phone every 6 hours. Does anyone have any idea how to improve battery life on this freakin' thing? 6-7 hours on light usage is not enough. To put it in to perspective, I get 10-15% battery drain in STANDBY per hour. Serendipity 6.4 was a little better than 7, but not much. still within that 6-7 hour range. Is there anything else I can try? Anything at all? I went from 7 back to 6.4 because I thought Android System was draining my battery, but it didn't really do anything. I'm open to everything at this point. Voodoo, cult magic, anything.
Edit: reading through my message, I wanted to clarify that I am very grateful for your help, I hope I didn't imply otherwise.

Have you tried Juicedefender? It's helped me immensely. Other than that, I could suggest getting an extended battery, if you're willing to cope with a lumpy cappy. I'm too noob to know how to fix this problem other than by using the brute force route, but it's worth a shot.

Well, battery usage shows just about nothing... I was using 6.4 but after it did nothing for my battery life, I went back to 7. Now the android system thing is back but I'm getting the same battery life.
Here's what it shows under battery usage for today:
Display 29%
Android System 25%
Android OS 10%
Google Services 7%
Cell Standby 6%
Fancy Widget 4%
Handcent SMS 3%
Battery Graph 2%
Phone Idle 2%
JuiceDefender 2%
Dialer 1%
and that's it.

if you start seeing android system and android os that high, shut down, yank battery and let it sit for a few minutes. then replace and start up. should help with that and improve battery life.

The problem is, I'd be doing that every 15 minutes. It boots up already taking up more than 10%. I just did exactly what you said, and it booted at 23% for system and 3% for os.

flashed cyanogenmod 7, and turned off mobile data and wifi and just left it on idle for like 2 hours after resetting the batterystats.bin and rebooting... i uninstalled juicedefender because it was actually USING batter... *shrug* and left it that way... well, I opened battery left and looked at it and saw that it would die at like 5am... well, i was disappointed... until I noticed it was 5am, 26 hours from now. That's notibly longer than any battery left stat I've seen since I started noting battery issues... So... Yeah. I think I'll stick with CM7 for a while hehe. After I get an idle benchmark, I'll start using it more. Thank you for your help.

do you live in a poor 3g area?
the problem could be that the phone is constantly looking for a good connection and cant find one, causing massive battery drain

I was just going to say the same thing. If your phone is constantly trying to establish a connection, is alway searching, it's using up lots of juice. Same if you've got gps enable or wifi on. If it's looking, it's active and battery's being used.

Another thing you can try which helped me is to call art and get another free battery if your phone is still under warranty. The new battery I have seems to last almost twice as long as my old one. Of course make sure that the android os isn't eating the battery and mine last a while. Just a suggestion.

REALLY bad battery life, is this normal?

Heya,
I've used my One for a few hours now, I'd say moderately heavy use (checked facebook/twitter, downloaded some apps, watched a few youtube video's, played Dungeon Hunter 4 for 30 minutes or so, checked flipboard).
I'm amazed by the poor battery life, especially since all the reviews were so positive. Will it get better? Could I have a faulty battery? This is nowhere near the 14 hours people have been talking about...

you can't tell yet. @Zepid, look for better battery stats xda edition and install it and post the screenshot for kernel and partial wakelocks, other and process.

It's hard to really tell with the default battery monitor, try BetterBatteryStats or GSAM from a full charge and go from there.

Also turn Power Saver on. It limits the CPU to 1.1GHz, and won't even affect gaming performance, or anything else for the matter except benchmarks. Click on the Power Saver option to customize what gets turned on/off.

You should check out the thread that talks about battery saving tips. It helps a lot and make sure you install a custom Rom such as trickdroid.
It's very battery efficient.

Don't forget that if you install a custom ROM, you'll need to root your One. That also means loosing your warranty

DH4 is a beast on battery in my experience. It is hard to play that game and not burn a ton of battery.
Anyway, when I don't play DH4 I still get 5 hours screen time. That's without power saver, auto sync disabled, and Lux adjusting screen brightness. I'm sure if I used power saver I'd get much longer.

Seriously, give it a couple of days!

Thanks guys, the Power saving feature definately seems to help, and it's not slowing down the phone at all. I'll give it some time and see if the battery life improves.

You should allow more time, at least 2 or 3 updates, to iron out the biggest bugs. All manufacturers need that time, apple en Samsung too.

How I am getting good battery life: A simple guide with some links and stuff!

I see a lot of people complaining about battery life, myself included. I have tried just about every ROM there is and used all the battery saving apps and I think I've found a winning combination that will leave you with a fast phone and good screen on/off battery life. My stats so far today are 8 hours off the charger with 1 hr 30 mins SOT and still 80% battery left and that's shifting between my work WiFi which has many access points and causes WLAN_RX wakelocks and the crappy signal around this area.
I use the phone for general stuff like browsing the web, playing the odd 2D game whilst bored and push notifications from various social networking apps and I have been addicted to achieving 7+ hours of SOT over 2 days since I owned a Galaxy S1 many years ago. Instead of writing a crazy guide I'll just keep this thread simple and post my current configuration that is giving me good battery life:
- BOE2 bootloader, modem and ROM (I'm using Nameless ROM v2 for 910G)
- Roughly 25% brightness, all sync on, location @ GPS only (High Accuracy only when using Maps)
- Followed THIS GUIDE very closely which gives amazing deep sleep and still get notifications with the Push Notification Fixer app
- Uninstalled Facebook and Messenger and use Tinfoil with Pushbullet and the RSS Feed and set to open Tinfoil when I get a notification: Here's how to do that
- Discharge fully to 0% and then turn on again to make sure fully dead, then charge to 100% to calibrate battery
Wallah! You should get good battery life now provided you use the phone for the same things I do. It's that easy!

You need to be rooted for most of that thread don't you? I need my banking app from time to time so I can't root. Gutted!
Joe

Thank you for taking the time to write this up, but you should mention in the thread title that you need to be rooted. Thanks anyways though. I'm not the type to root. If Samsung can't deliver a good product for the $800 device they made, the device should be returned (which will be my case if the 5.1.1 update doesn't come in July or it doesn't fix the issues I'm having with this device).

Fully discharging a Li-Ion battery is not healthy for the long term life of the battery.
When will the myth of "re-calibrating" a battery finally die?!?
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life.

Smartphone batteries haven't needed to be calibrated in years. The only time you ever had to "calibrate" your battery was when your phone would sit at either 5% or 1% for hours before dying.
Even then you were calibrating your phones interpretation of the battery voltage levels, not the battery itself. Unless I'm very much mistaken battery charging is handled by integrated hardware, not software.
As a software bug overcharging a Li-Po is dangerous and completely avoidable

Huh? Never had a problem running official apps from two different banks.

I'm finding TW to be slightly better on battery under my circumstances - which consist of terrible signal fluctuation and rx_wlan wakelocks due to so many wireless arrays at work - however I will probably go back to CM12.1 soon or wait for Android M developer preview to be ported to Note 4 (fingers crossed) as I just love how stock and minimalistic everything is on stock droid CM and AOSP and it seems to be a lot snappier when combined with L-Speed mod.
