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 :]

Rom with the best battery life

I don't know If this thread has already been created if so please direct me to that thread.
So I used to think CM6 had the best battery life so I flashed 6.1.0 but not much battery life change so im starting to think that maybe it was actually cm 6.0.0 that had best battery life but im unable to find it so I can test it. So im here asking you all what Rom has brought you the best battery life to your cdma hero no matter if its 2.2 or 2.3
CM + AOSP = DABIZZNIZ

I would like to know what's your measure of "best" battery life?

try using aosp - jaybob's rom, best rom with battery life, used it pretty heavily and got 15 hours

My measure of best battery life is not losing 10% of my batery life doing nothing. I remember when my battery would be be at 40% I go to sleep wake up and its about 30%, now its dead by the time I wake up

don't need to flash the kernel since it's already in the rom. Just do a full wipe and bam ! I'm actually trying the latest one (june-08) but the june 4 version gave me that 15 hour

personally i have found that the rom you choose itself doesnt really matter, its more about your personal usage, i.e what apps u have running, cpu settings, etc. i usually get around 15-20 hours battery life with pretty heavy mp3 use, lots of texting, and about two hours or so actually on the phone. but i make sure i leave data/wifi/gps etc. off unless i need it. also, its a good idea to check and stop apps that automatically load with the phone that you dont need. imho the only roms that seem to drain the battery quicker are the sense based ones, at least from my own experience.

I was thinking about starting a new thread about this, but you are explaining EXACTLY what I am going through. I wake up today (after leaving my phone charging at night) and turn on my phone, and first thing I see is an 80% battery (this is a normal occurance). After literally doing NOTHING on it all day (except for a 30 minute call) it turns off by itself at 20%.... after 8 hours. So while I got 2 hours better than you, keep in mind that I did virtually nothing. What is worse about it is i'm supposedly using the "best rom" for battery life (AOSP 2.2. + battery tweak).
I've wiped battery stats (after reading the correct way to do it) and checked the health of my batter (reads as "good") and i'm still clueless. I'm wondering if I should even waste my money on a battery and hope that's it? I've only had the phone exactly a year and about a week so I'de be disappointed to know the battery lasts this short. I remember being on another froyo ROM (with the battery tweak) using it more than I am now going to bed anywhere between 30 and 50% which is about where it's at at lunch time now! I can't believe that i'm actually ok with the performance of my hero, it's just the battery that's killing me now !

And I plan on staying away from the GB ROMS until they get the GPS issue resolved. Let's just say that I was in Colorado a couple of weeks ago and my phone failed when I need it to work.... flashed froyo almost immediately when I got back (that's another topic)

i believe you are correct, if you got it from the download section of rom manager, its the same one, ben using for a while now, no FCs no issues. smooth and pretty fast too

frustration with my crappy

I have it rooted with gingerbread 2.3.5 and i am not pleased.
my phone was slow. like making me mad slow. Its like my phone only wants to be fast a couple. I had launcher pro , go sms and go key board. But then i uninstalled all except launcher pro and removed all my widgets. and its a little faster but its still really sluggish. also my battery seems like it goes down pretty fast.
Should i download a new rom ? Im thinking of getting a new phone also. i was thinking about an iphone but not sure .

Wich 2.3.5 and kernel?

I have Jvs

Well I can't offer any help on a I9000 rom. Haven't been on one of them for a while. I would recommend you trying a native rom. But Have you tried reflashing that same rom you are on?

is it stock or the custom rom? I am running S_Bamboo rom based on JVT and talon kernel...its really really smooth, fast and decent battery....

Im on apex , and i have tried reflashing . Im going to try a different kernel

My captivate was running extremely slowly (almost unusable) when I was running Mosaic VII. It was so bad that I almost dished out ~$600 for a new phone (contract wasn't up yet). As a last effort, I decided to try out CyanogenMod 7. To my amazement, my captivate is suddenly extraordinarily fast and ridiculously usable! The data connection is actually fast (used to take about 7 minutes to update Pulse (news reader), and now it completes in under 4 seconds), GPS is still meh but better than previously, and the phone interface is very snappy.
If you haven't tried it yet, I would highly recommend CyanogenMod to see if that solves your issues. It saved me a buttload of money since now I don't need a new phone until my contract is up!

how is your battery life though? I personally have had the best luck with pinnacle.
CM and miui had awful battery, and i would often have to turn off and on the data (at least once a day).
this also was when i was using nightlies (maybe a month before the stable release came out) is there any difference in the rom now? Should i give it a shot again?

CM7 has been great for speed and battery life for me. Absolutely astonishing. I don't even care about the SGSII anymore.
PS If you try it, I suggest doing a complete restore, i.e. not using Titanium Backup as it seemed to slow things down for me.

Going to give it a shot when I get home.
I'm optimistic, but I really can't see how it can even come close to a kh3 ROM.
If I just leave my phone in standby, after 10 hours, it might only go down to 85-90 percent. Last time I tried cm, it would go down 5% an hour.
The last nightly I remember flashing was around build 100 or so. Have they fixed the proprietary driver issue that causes the bad battery life?
Should I go with glitch kernal? Or stick with stock? And what glitch should I go with if I do use glitch?
Fingers crossed that it works better this time!

My battery life is actually extremely better than it was with Mosaic (and previous ROMs). After a day (from 8 AM to 11 PM) of pretty heavy use (reading emails, Pulse news, non-stop texting, and web surfing), my battery is probably between 10-20% left. Obviously thats not a lot (definitely requires a charge every night), but compared to my 8 AM - 5 PM (completely dead) battery life previously, it is a substantial increase. I have found that it drops from 100% to 60% pretty damn quickly, but then hovers in the 50-60% range for a long time (playing a 3D game for 30 minutes made it drop from 90% to 75%, but on a different day, the same 3D game for 30 minutes went from 66% to 65%).
I would definitely give it a shot again. I wouldn't do a backup and restore of your apps though....I'd reinstall each one again manually (you can restore the data to some apps if you want). Also, clear all caches and battery stats. Don't freak out if your battery dies to ~60% after an hour...it will stay around that percent for almost the entire day.
PS: On standby, this thing is a beast. From 8 PM to 11 AM (on standby completely while i was sleeping), it only lost 1% battery life. I don't use anything like Juice Defender or anything. Data was still enabled.

I've been using Serenity rc4.1, and about to flash rc5. Been fast, stable, and good battery life for me. Light use yielded me 1 day and about 17 hours on a charge. Haven't had any problems with wifi, gps, or really anything else. Good luck.

Well I'm on it right now and I like it better compared to apex. I can tell try hat my battery life is better. Does anyone know the best modem/ kernel that I can get for my phone

I use the stock kernel without any issues, but I've never tried any others. Modems are very geography dependent so it will take some trial and error. I am currently using UGKG3 with great success if you're looking for a starting point, and I've also had great luck with JJJV5, but YMMV.

Well, I'm writing from SGS2 right now, but I do have SGS too (my working phone no.), and I was not satisfied with with any stock (or/and) deoxed ROM I've tried (JVH,JVK,JVP,JVB, JVO,JVQ.....), because even fresh flashed or (and) tuned ROM felt sluggish to me. I've tried even few CM7nightlies, but I've been pushed away by some of it's aspects (it was fast, rock stable, but something around nightly #80, it wasn't mature yet for daily use). After a while on JVQ, I've finally decided to give that crappy chineese piece of **** a go...
Well, now I'm satisfied. MIUI ROM is based on CM7, so it's stable and fast, it can be configured to the bone, and with some gentle touch from MIUI team to the graphic design, it is best compromise between graphically advanced, but slow and unstable Samsung ROM and it's derivates, and superior rock stable and reliable CM7 which lacks any unified user friendly interface for all apps, and some details may not even work at all.

So my phone was all the way down to 15% and I had practice, so it was idle for 2 hours and when i looked at it it said it had 25% left. and then it was idle for another 20 min and it said it was 27%.

How's your battery life on the incredible s ?

I'm not sure that if my phone has a low battery life or others as well . When I go to bed , my phone was at 70% and I wake up after 8 hours of sleep . My phone dropped to 58% . Is that a normal case or should I get a new battery pack ?

i'm using 1800 mugen power battery. it's better on about 20/30 % and you can really see that. so if you want to buy new battery - better buy this one than original. i'm working with it for half of a year n everything is fine.
about your battery - yes, it can go in that way and its normal for our dev.

Mine is about the same as yours, 100% at sleep and 88(at times it's 87 or 86) or so when I wake up. But I think I slept for about 10h
Edit*
Atm it's at 80% and it has been on battery for 13h exactly

im having issue with poor battery life on this device too up to 5hrs ~)

A tip is to disable sweep2wake if you have it enabled. it consumes a lot battery. Since I disabled it yesterday my battery gained a couple of hours battery life.

Using Longevity on CyanVivo X Rom and very impressed with the battery backup, Lasting over 18 Hours with average 3G data use and gaming before it was like 8-10 hours with Juice defender. Don't keep data on all the time otherwise use longevity Worth a try!

Imo it's just placebo effect. I actually think that they waste battery than save.

About battery saving apps:
Some might help save some of your battery, like Juice Defender, but about 100% of the stuff that an app does is something you can do for yourself.
Like dim the screen when you don't need 100% brightness, turn off data and use only GSM when you don't need to use data (and if 3G has better reception it might be worth staying on 3G though, at least in my world a better reception would mean a little bit better battery than if you changed to the network mode with worse reception) and when you don't need WiFi - you turn it off.
Using apps to kill other services and apps are not a good idea either, since some apps will only restart and restart and restart while the task killer will keep killing = both apps will drain your battery.
And by turning off both WiFi and data and the apps are well designed, they should not try to look for updates and such if there are no available internet connections.
And, by undervolting you gain more than using different apps and such and if you then learn how to set up your device in the best way for battery you will get longer battery life.
If I don't use my phone so often, I can get about 2 days with 3G/GSM + WiFi turned on all the time and mobile data connection turned on all the time. If I use it a lot I still get long enough battery time to make a full day, usually I need to charge my phone every 18-24 hours when I use it to check mail, send some texts and read news (and XDA, as the addicted person I am).
Now, I just hope that I haven't f*cked anything up - I'm just too lazy to read it through.

I bought myself a Nexus 7 about a month ago to satisfy the cravings for that Jellybean goodness. After trying several ICS/JB roms on my IncS over the past year, I decided to revert back to the CM7 Nightlies. Much to my surprise it's almost as if I forgot how blazingly fast Gingerbread was.
Given how i use my IncS on a daily basis, I seem to be averaging around 34-36 hours before it hits below 5%. It really only gets used for calls, texts and wifi tethering to my N7.

I used to average 30% battery drain per day with light use with stock GB rom and kernal, it has upped to approx 50% per day with stock ICS rom, with lOst profit's overclock kernal running at 1400 wake and 368 sleep. ( setcpu )
Not bad considering 40% increase in processor speed, but less than 20% increase in battery usage.

I tried latest cm7 nightlies and it wasn't smooth at all so I reverted back to jellybean cyan x
don't know why you are saying that GB was blazingly fast...
My battery is so bad on the jellybean ROM though!!
So 1 sacrifice for another :S

You must be doing it wrong, I'm on nightlies 146 with Tiamat kernel and this thing is like lightning. Battery lasts forever on moderate use about 36 - 40 hours. Lag is no where to be found.

keep in mind you have to give it a couple of hours , maybe even a day(depending on how much it has to do and your connection etc) Before the rom settles down after flashing. Then you can give your impression of it if it is laggy or not.

Anyone use nitrogen and pure nexus and has a preference?

I do so much work on my phone so need one that is smooth and quick with great battery. I have Pure Nexus now and it's fine but sometimes it seems to lag. Maybe they all do when jumping through lots of apps. Maybe I need to reboot daily to keep it smooth.

I don't think it should lag but you may give custom kernels a try.Lag sometimes happen due to throttling after heat.Custom kernel manage these issues at ease.

OK thank you. I have 3.10.40-PureKernel-Shamu-2.04 so it's a custom kernel meant to work fine with PureNexus I think. I'm sure it's just because I'm using nav, and other high usage apps.

IMO android uses a very smart way of managing stuff when multi-tasting to reduce lag.So it is still highly doubtable.
Why don't you try some other kernels and overclock possibly?

Right now the phone doesn't last till much past 6p so I don't want to clock even more in case it uses more battery. It used to last longer so maybe when updating to 7.1.1 with the newer Pure Nexus that took some more. Or maybe it's just a 2014 phone with high mileage =). I used to go to sleep and overnight it hardly used energy now I notice when it's just idle it can use 20% overnight, maybe more. It could be an app I downloaded is running.

I use Nitrogen and no custom kernel and get above 6 hours screen time, very good ROM!

Awesome thank you for that. I'll probably give it a try. I think it was in the top 5 custom roms on an article I read.

i finally switched to 7 on pure nexus...it's great...smooth...fast...had it running almost 300 hours without a reboot and it was still going strong...i haven't tried nitrogen...so can't say...but am happy with pn...i came from chroma rom...

Roms, Kernel, and Age are all irrelevant!
A phone will last as long as the battery allows, and that's based on your usage of the phone. Period!
You use a lot of apps, it's going to die quicker.
You stream a lot of music/YouTube, it's going to die quicker.
There is NO magic combination of Rom+Kernel that is going to magically make your battery last longer.
Your battery has X amount of usable stored electrical charge, and your phone will use it accordingly based on what you do on it.

So you're trying to say using Rom and custom kernel can't help increase the battery backup(SOT) of a device?

I don't think he understands or maybe is oversimplifying what he means. The Rom and the Kernal which affect the amount of systems running will affect battery life. The age as in the amount of times you've discharged and charged your phone over months and years will affect the battery life. There are tons of variables that affect it. One can say the kernal and the rom if they are running more systems or less then that's what he means by saying if you use more apps then it uses more battery but that isn't magic that's just use. So if you put a certain kernal and rom then that is affecting what you do on it which affects battery life. The X amount of storage a battery has degrades over time. The first answer when googled is below. I probably have almost 1000 charge cycles now. Nothing I can do about that.
"Charging a battery forces ions from the cathode to the anode; using the battery reverses the flow. Over time, this process wears out the cathode, which results in reduced capacity. A high-end lithium-polymer battery can lose about 20 percent of its capacity after 1000 charge cycles."

Not if you have a bunch of garbage apps running in the background, constantly running some kind of process to check for incoming messages/app notifications/location tracking.
You wanna know how i went from having 10% battery life at the end of a work day to having over 50% battery life???
I stopped installing **** on my phone that i didn't absolutely need.
And low and behold, my battery life "magically" increased itself.
