GB 2.3.4 on vibrant, battery sucks ass - Vibrant Q&A, Help & Troubleshooting

hi,
thought on moving to GB from froyo.
so i went and installed every non CM7 ROM in the 2.3.4 forum list.
all of them had problems on my phone with one shared problem that all had, bad battery life.
i did all the calibration needed but it didn't change anything.
i'm talking about a phone with no services except gmail and exchange.
battery on 2.2.1 used to hold for me for around 25-34 hours of usual usage(with still around 20% left).
on GB ROMs it was around 8-10% per hour.
does anyone have a clue where to begin ?
while looking in the battery stats and in system panel software i've noticed that the android system process is the top cpu/battery consumer.
i've also noticed that the phone is slow on most of the ROMs i've installed.
thanks for the help.

Battery on any of the Gingerbread roms that we have available is not going to be as good. Just the way it is. If you are using CM7 try the Glitch kernel. It provides a bit of improvement over the stock CM7 kernel for me.

I have the same problems with my vibrant, the I9K roms seem slow and kill the battery fast. I was only trying them because all the Vibrant Froyo based roms (ie: Stock or Bionix 1.3.1, etc...) have bugs that seem to only be repairable by rebooting the phone (ie: stops ringing when people call... gets the call fine, but doesn't ring. Also, stops being able to play some music formats, only starts to play them again after rebooting, etc...) I can't wait to replace this phone, total PoS IMO, My G2 works far better (Vibrant is actually my wife's phone) and is far easier to try out different roms.

thanks for the quick reply.
i would have understand if was 20% worst, but no holding for 12 hours and then die.
by they way, are they suppose to be slow/laggy also ?
there are also many new services/system services, my phone has around 40-60 MB less than in froyo.
i didn't try CM7 because as i understand the GPS is not working in them.

Ummm no. Try trigger redux. Yes the battery ain't froyo but GPS locks on 7 sats and Birg put a ton of work making it snappier than any froyo out. Trust me, the speed is insane. Anything cm7 based is worthy of being your daily driver. It makes my phone awesome yet again.

Best battery life.

Alright, I'm on the quest for the ultimate rom. Specifically for battery life, but I want a good honeycomb or even honeybread mix with good/great battery life. Im getting decent battery life with Nero v5.

These battery life questions are being asked all the time. Try looking around the forums a little bit and see what people have to say.

All the ROMs you will find will have the same BASE battery life (since they are ALL based on Samsung code [except CM of course, which has worse battery life as of right now]). Here are the factors that DO affect it:
apps
gps/bluetooth/wifi
low signal
kernel
Obviously the biggest eater is the screen. No matter what you do, you'll get a max of around 2 hours display time (that is, 120m of the display being turned on).
The next eater is data. Apps that refresh themselves in the background are notorious for eating battery life. Twitter apps, facebook, or widgets that update automatically are the first thing to look out for. I believe they all default to automatically updating or something.
And if you use the stock voodoo kernel, that will give you the best battery life out of all kernels available.
I get about 4 hours of display being on with the lowest brightness setting. Stock battery, 2 hours is very low.
Yeah I have the brightness as low as possible. Im only getting 15 hours, and I've heard rumors of up to 20 hours with some roms. Any body know any good gingerbread mods with good life?

White's version of gb will give you better life. CM7 is 12-14 hours with poor standby time.
Best battery life will always be axura.

if you want battery.. Its always been either axura or nero/bionix
Battery life is entirely too subjective a topic to get hard data from.
- People running different roms
- People running different kernels
- People running different modems
- People running different background services
- People knowingly or unknowingly running apps that create excessive partial wake usage. Or not running them as the case may be
- People with widely differing signal levels, which vary from area to area
- People with different screen preferences (insofar as brightness, auto brightness, animations etc...)
- People with Vibrants a month old and Vibrants nearly a year old. (i.e differences in battery degredation)
The only way to get a quantitative set of real data to work with would be to painstakingly eliminate all the above variables per case, which would mean (at this point) dozens or even hundreds of dedicated test scenarios.
I've recently ran Bionix, Bionix Frost, Trigger, Sweet Honey, Atriarc, and Darkys (yeah I get bored a lot...sue me ). I've yet to notice a significant enough degree of difference between any of these in regards to battery life, running the stock apps and services I always run. Enough to notice? Perhaps so, but only if I were going through my day with a stopwatch (which would seem a bit anal). Enough to care? No.
I'd rather just use my phone and say "screw you guys I'm going home!"

super noob question, will the themes involve the tv turn off into sleep mode? or is that a bigger form, like kernal etc.

Nope.
Any 2.2 or 2.2.1 build will never have that its integrated into gingerbread and as far as I know you cant just copy and paste..
But there are alternatives such as a app someone made that locks your phone using the search button and shows the tv out animation
It really just depends on how you treat your phone, I text a lot, and only check xda and I get about at least 19 hours Stock kernel, and now I'm trying out Tigersblood kernel, and I undervolted my cpu clocks, and set setcpu profiles in Setcpu, and downloaded Superpower from the market (turns off data when screen is off) and monitor about every other week which apps I installed are eating my battery (if any) using System monitor, and I should atleast get about a couple more hours ;]

On that part where you talk about super power, I use juice defender, and I turned that option of that turns the data off when my phone goes off because it would take to long to come back on. Is there a delay?

most economical rom?

Hey guys I love all these custom ROM's but honestly the battery gets drained so fast it takes the fun out of it. I was wondering if there was any specific ROMs that were easier on the battery>?? The only feature I truly use on these things is the wifi tether, other than that I don't care if the phone is a litte slower etc, i just want to be able to make it a day on 1 battery..TIA
I can easily make it a full day with the PowerWashed 2.0b3. Yet I also have Juice Defender Ultimate installed.
Ill be quite honest, gingerbread is not what its cracked up to be imo... I have found that powerwashed 1.2 ed05 froyo w/ pbj 0808 kernal is one of the most stable roms out there. Im getting between 1.5-2% percent battery drain per hr. That means I go 2 days without charging the phone with normal use. Heavy use such as browsing the internet for a couple hrs and sending dozens of texts usually equates to charging the battery once a day or slightly better. The only issue is not all fascinates play nice with the -100 undervolt that the pbj kernal has built in. If thats the case, then just run the otb fusion kernal that come with pw 1.2...battery life is still good(2.5% per hr) and you can overclock with that kernal, but truthfully overclocking does not really improve much imo.
Wow thanks guys! Yea I am on MIUI and its horrible.. I will look into the ROMs you guys suggested..thanks!
vanilla gb is insane. running with the glitch 9/15 kernel, undervolted, smartass, noop and usas tweak applied, simply the fastest rom i've ever used battery is also holding up really well, but I have the naztech 2400 installed just yesterday, so battery should only get better with more charges. pwgb is also really good, but the file system is still samsung rfs, which is really slow. Pw froyo is probably the better choice for most people with pbjt kernel which has voodoo. Ill stick with vgb and see how battery does and if it doest yield me 6hrs of screen on time ill switch back to pw froyo and see how it does.

I went ahead and did the switch to ed05 pw 1.2... What kind of probs would I have if the pbj -100 didn't agree with my device?

your phone will freeze up...if it didnt your good to go! Make sure you wipe battery stats in cwm or it will take few charge cycle before you get good battery life.

Ok sweet! Yea, everything seems to be good, only issue I am having is in BLN it says the Biblight isnt working or something like that..Voodoo control is g2g, just the BLN. I'll have to look into it
I had the same problem with bln not working on this kernel. What worked for me was to flash the older 0531 kernel first,then flash the 0808 kernel. Bln works fine after that.

Actually pwgb beta 3 with adrenaline shot mod is yielding some crazy results for me. Screenshots to follow when battery decides its held on long enough.
Only my 2nd day on ED05 powerwashed w/ pbj0808, but man I must be doing something wrong. At BEST my battery is draining roughly 5% an hour and thats with practically little to no use. NO clue how you guys are getting such good battery life...
Seriously, just odin the pwgb and flash the adrenaline v7 and thank me later.

What kind of programs do you have open/on, on a daily basis? I found that twitter absolutely destroyed my battery. I actually turned notifications off unless its a DM or @ me, otherwise I just open Plume and refresh to read the timelines.
Its doing A LOT better since then. I haven't used the phone much, but its only at 75% and Its 140pm, been off the charger since 6am
I am gonna see how it is this weekend when I am actually using it more
@Droidstyle: I was thinkin of trying out for starters the rom you recommended "powerwash 1.2 ed05 froyo w/ pbj 0808 kernal" but when i did a search for powerwash 1.2 the thread mentioned that it was outdated and to try gingerbread...just a little confused since i'm still new at this: considering my samsungs fascinate uses this base band (this is the general info of my phone Model : SCH-I500
Firmware Version 2.2.2
Baseband Version: S:I500.04 V.ED05
Kernel: Version 2.6.32.9 )
i will have to use a rom that supports ED05? or am i okay to try out any of these roms? did a lot of reasearch today, just trying to narrow it down as to which rom will be the most apt for me (meaning which one will i get the best use out of) and what will i be able to do after that? do i apply themes from the themes section, or i can only do that if they correspond to that specific rom? to anyone in the room please enlighten me, i've spent almost all of today researching this and would greatly appreciate help from the experienced...

Im not sure why he did that... Its a very functional rom and is up to date as much as it needs to be. Read my guide, uses that rom for an example on how to install a froyo rom. You are not limited to what your base band shows, you can flash 2.3.4 gingerbread roms if u like,, but they still have a few minor bugs. Actually 2.2.2 pw 1.2 ed05 is the most functional rom up to date imo... everything lse still has minor bugs to work out.
@DroidStyle thanks man, your guide to flashing power wash is pretty direct, but i'm a little lost here...Isn't the Rom mgr. program you install for the market used for flashin the Roms so that you don't have to odin the rom to the fascinate? also, can I apply whatever themes? ...ie: are those used to customize ur GUI?

Stay away from rom manager!!!! It only works for the mtd based roms such as cm7, miui, aosp... even then odin is a much more reliable way to work with the fascinate. imo just get use to the fact that your going to have to use odin most of the time when flashing.

Which ROM are you currently running? Which have you tried?

Just a thread to see what the majority of people are choosing to run right now and which you have tested as well. This is NOT intended to be any type of a bashing thread, just please stick to what you've tested and what you've chosen to currently use.
As for myself, I'm running UnNamed from gtg and have been for a bit now. I've removed a few additional pieces of software that I didn't want and modified the battery icon but other than that, it's pretty much as is.
I've tested and have a backup of CM 7 and I'm planning to test Cognition next...
I am running UnNamed, I had a circle battery mod, but flashed the full update and have stuck with it as-is. I ran Cognition with no issues or complaints, but wanted the extended power menu.

I'm running Cognition as of yesterday. For a few days before that I was running a stock + root ROM.
I must say, my battery lasts sooooooo much longer since installing Cognition compared to Stock. I just now hit 90% and it's been off the charger (getting regular use: some idle, some web browsing, some pp installs) for about 6 hours now.
I love it.

I'm on Cognition and haven't tried others, yet. It works and as ROMs have appeared, I've pulled what I wanted from them. I get great battery life (3 hours of display time, but lately it's been increasing - yesterday I got 4 and today I'm on pace for over 5 hours of display ). I'm really interested in CM7. I hadn't tried it yet because I'm not convinced that it's bug free (which is important for me). What did you think of it?
I'm getting such poor battery life still, even after rooting and removing data hogs (AP Mobile, etc.), running BBS and CPUSpy to monitor, and turning off unnecessary sync. I'm thinking about moving to Cognition, but I kinda like Touchwiz's interface and the safety of running stock.

I liked CM7. I probably didn't give it enough time to make an accurate assessment of it as I liked the idea of trying UnNamed simply because I like the stock build as it is... minus the garbage bloatware and wanted the extended power menu. I'd highly recommend giving CM7 a shot though. I simply get each rom running and then do a full nandroid backup in case I want to go back in the future - barring any major improvements of course in which case I'll start out fresh.

I have to say that I was never much of a believer in Juice Defender but between running that program and doing a battery calibration with the app, BatteryCalibration, my battery life has increased quite a bit. I've still got Gmail auto syncing but I have turned off 'Back up my data' in Privacy and keep GPS off until I need it. Everything else is running as is. Oh and no Facebook or Words with Friends. I login to Facebook via Dolphin HD when I have to check it on the go.

Ive been on cog beta 4 for a while and it is perfect. Picked up DD exp kernal a few days ago and its still perfect. Perfect combo i guess. Battery life is amazing. After 15 hour days i am always getting 4 hours of screen on time along with playing music thoughout the day and few calls and messages data and sync always on.
I have yet to have any problems and gonna make this my offical "go back to, stable rom" when others start to drive me nuts. I would like to just stay on this rom and call it good cause its perfect but that never happens.

Fascinate CM7 standby battery drain

So i have a verizon fascinate and am currently running cm7. (first tried the stable release but niw a nightly). Im eeally liking cm, but since i got it my battery life is garbage. Basically the drain seems to come from either the android os sercice or cell standby. Whenever i leave my phone inactive for a while, when i wake it up the battery has dropped a lot and tge phone is very warm. I have been modding this phone for a while, but im no android programmer. Purely based on the forum searchi. G ive done on the issue, it seemsblike cm7 has an issue with my modem or radio.
Extra info: my 3g/2g signals seem fine (always 0% time without signal). Wifi connectivity seems fine. Im also running glitch's kernal altho the problem has persisted with and without it (i did do a kernel cleaning first). I used the "go from anything to jb vanilla" guide cuz i was having issues switching to mtd at first (sry dont have a link rite now but it was on xda) . I get occassional force closes, but not really a problem. When i did a titanium back up, the very first time i flashed cm7 i Did restore system settings, but i did not do that every time since then. Ive done a fresh flash of the stable mod around 3 times trying different stuff, but this one is niggtly as i said, and each has had this issue.
If looked around a lot, and wgile this seems common, no one has posted a consistent solution or explanation to the problem, so thats what im looking for.

I have had the standby battery drain on every CM7 version and Kernel tried so far including 7.1 stable,7.0 nightlies,JT's Vanilla,and PoolParty. It's even worse if I shut phone down and don't plug in. It will drop 50 to 75% overnight with phone not on?
Has done it with undervolting,overclocking,and voltage control not even installed. This is first time I have seen others having similiar issues.
I think this is a known issue for all MTD roms on the fascinate, if I'm not mistaken.

I lose only 5% to 10% overnight on CM7 never really notice how much on MIUI cause I never ran it long enough. I guess every phone would behave differently for MTD's or maybe you have an app or mulitple ones that refreshes frequently(Fancy Widget comes to mind).
Well that really sucks, because i do enjoy cm7. But this also means if i go back to a touchwiz configuration like stock dl09 i shouldnt have these issues right?
But before that, has anyone who had these issues tried anything (ie kernels or maybe standby mode power conservation setting, etc... ) that have at least noticeably improved your battery life? Right now mines pretty unbearable (im talking 8hrs while on but totally inactive), but if i can get it up a little i might b able to manage.

I am also experiencing poor battery life. I just flashed 7.1.0 yesterday and absolutely love it. Was using com rom for a few months, but a friend said to try out cwm 7. I used to get about 6 - 8 hours of Pandora while at work and today I only got about 4 before my phone shut off. I'm going to try completely killing battery and charge with phone off tonight an see if it's any better tomorrow.
Any other suggestions? I'm not a noob when it comes to custom roms and flashing (I used to flash the **** out of my G1) but there may have been something I over looked when switching to cwm7. I wiped everything a few times before flashing including battery stats and dalvic.
My battery life is actually really good. Running latest nighty, undervolted -75 across the board,stock kernel, and no overclocking.
Just can't figure why I lose 50-75% of battery overnight when phone is shut down and not charging?
I have the same issue with CM7.1, turning phone of at 80% battery at night to find it at 25% at morning
Is there knows solution?

CyanogenMod 9

I've been reading up a lot about custom ROMs, and more often than not CM9 always gets a mention. I'm tempted to flash it but just wanting to know is it really worth it? Does it have major improvements on battery and performance, and what are the main things that make it so much better than the stock ROM?
Also is it easy to revert back to the stock? I've already got my phone rooted with CF-Root, is that the clockworkmod recovery I've read about, and if so can I just go ahead with making a backup and flashing with CM9?
Any help/info would be appreciated.

Its users choice read what does not work first .
CF root is not Clockwork Recovery but it probably has CWM recovery incorporated .
CWM manager in apps and boot to recovery should show CWM options .

CM9 is experimental and still has several flaws and issues.
I'd not recommend it for everyday usage if you're not a developer or like living on the edge.
Plus, 3G battery life is terrible since CM9 has no Fast Dormancy. Within ~5 hours the battery was always dead on me.
Samsung-based Roms make it more than 24 hours in contrast.
It will of course get better when the ROM is properly fixed and all features integrated. It always does =)

Flash Stock firmware through Odin, then factoryreset the phone in CWM. You're back to stock

So that must be the drain issue everyone is talking about. I use 2G only on T-Mobile and I get awesome battery life haha. Good to know I must be the only one

a lot of the battery issues are due to not resetting battery stats. You fully charge the phone, clear the stats, then charge it again I think? Search there are instructions.
I've got CM9 on an Atrix which isn't even a supported device and it's totally daily usable. The only things I lose which are only b'cause it's an atrix are:
Fingerprint reader
Webtop
video camera
Check out what works and doesn't with CM9 for your phone and decide. I like it a lot, it's TOTALLY stripped though, like no google aps (you can install them as a package)... There are lots of weird intricacies to it but it's cool as hell IMO

Resetting/erasing battery stats does nothing.

At least the build for Atrix is not pre-alpha EXPERIMENTAL =)
It takes some time for the developers to get it right on the S3. I've never said CM9 itself had issues, it's the combination of CM9+ i9300 that needs some serious work.
I have or manage a couple of CM9-flashed devices (from Galaxy S1 over Galaxy S2 to Motorola Xoom) so I know how awesome the Rom is =)
Cheers for all the replys.
Are there any other custom ROMs worth looking at? I've heard CM9 is the most popular but if it's not quite usable daily yet I might give something else a try.
CM9 is currently very usable. I have no problems whatsoever. It has many advantages to stock ROM like no low free memory problem, no launcher redraws and no lags. The only real disadvantage is that the camera app sucks compared to stock.
It must like your phone better.
Kept turning off the modem for no reason, sometimes restart was necessary to connect.
It also has no fd as already described, so many people will notice a huge drain in 3g.
Btw you can easily get rid of memory issues by freezing/removin, all the apps you do not need but which are always running.

I agree 100pct.
I don't even notice it's rom'd till I want to take a video or use webtop :-(
The tablet switching roms work great though. I played with jokers and LOVED it but couldn't get gapps installed for some reason.
