Maybe this is due to my lack of experience, but maybe not. It seems like every time I put a new ROM on my phone it goes to hell in about a month. I'm not a technician but I can follow directions for installation, patches, etc. So far I have had 0 long term success in installing a ROM that ends up being any better than stock after 30-60 days.
For example, I've had issues with battery drain, random booting while the phone is powered off, redraw issues, serious lag, data connectivity issues, and a few other things. It seems like its always something.
The only phones I've toyed with are my old Eris and my Charge. Is this a phone issue, noob issue, or is this par for the course? If it is par I'll end up back at stock and have mediocre performance rather than have a buzz saw that ends up needing constant tweaking and maintenance.
Btw this isn't a knock on developers. I appreciate them sharing all their hard work. I just want to know if everybody else goes through this or am I holding a bag of stupid.
Just rooting does nothing more than give you superuser access. It doesn't even do anything that uses the root specifically. Different roms do different things, but nothing to use battery...mostly they take things out rather than put things in.
Best thing to do is look at BetterBatteryStats and track partial wakelocks. That will tell you what is waking up your system and if there's anything spiking it, you can deal with it. Most of what really drains battery on this phone, other than bad apps, is somewhat random, and it will affect non-rooted phones just as much as rooted.
Must be something you did, picking a good rom make a big different. In my case. I flashed tweakstock to my daughter's phone since the first day it released (with tweakstock kernel), and never, I repeat never have any issue, when tweakstock 1.4 released, this is the second time I touch her phone and up until now she hasn't have any issue. If you use eclipse rom, PBJ kernel, Imonsey kernel, you're going to have issue. They are not bad roms or kernels, but they do have bugs. This is my experience.
Yeah, I think it's you. On stock, I'll be lucky to get 12 hours usage in a low signal environment. On a custom ROM, with custom kernel, I'll make it through the day. Of course, I've had a couple of random total crashes where I had to go at it again, but I deal with it.
PROTIP: the Facebook app needs to be told to stfu constantly. I would get an app like System so you can kill it easily-it still stays in RAM and in wakelock, taking clock cycles, even if you close it by backing out. I found that this was one of the best battery savers.

Yes, I agreed with kvswim, Facebook is a big battery drainer, I ended up using the browser for facebook, it's not as nice as the FB app, but once you get a hang of it. It's fine. I suggest if you want trouble free, ODIN pit file and original factory image, then upgrade to tweakstock with tweakstock kernel, then install Go launcher for smoothness. To save battery even more install battery saver by Antutu.(keep all default settings, don't play with it). You will see big improvement with both battery and smooth trouble free phone.

you really find a battery saver to be helpful. Every time i try one it ends up costing me more battery life than it saves.
As for the phone issues. Are you wiping data, cache, and dalvik before you flash? Not doing so can really muck things up. And a lot of times its just an annoying app that sucks up all ur juice, ie words with friends and facebook. I use them alot so I deal, but u can definitely tell the difference when u dont have those apps installed.
No i dont think its u...i have problems also.i jus made a post about my home/hard key...its always seems to b something after the next.but it looks like people find ways to deal and eventually conquer.also i appreciate wat the developers do.its alot of work and headaches.on top of posting and replying to many many people.its the roms that cause problems...constant tweaking and toying around...alot of times things jus need to b debugged a little it seems.but its all in the nature of what were all doing here.good luck to u

Hey. how about give the "battery saver" app by Antutu a try. This is one of the kind. It does not kill processes like others. It actually readjust cpu frequency during usage and put your phone in heavy deep sleep, after installed, let it run for 2 days, you will notice at least 3-4 hrs more during usage and 10+ if you let your phone sleep. I have test this app with wifi,4g,gps on 24/7 and I still have good battery life.
I downloaded betterbatterysaver to check my stats. Now to figure out how to read the data. Any suggestions? I've searched Google and it seems to be a mystery for many. It appears that Dolphin HD is using most, but I kill the program when I'm done???? I switched to mini and froze HD to troubleshooting. I only use FB browser too. I ditched the app long time ago.
Before I flash I wipe dalvik cache, data, and then wipe it again. I follow directions closely since I can't figure my way out if something goes wrong. I'm running tweakstock's latest right now and I'm really enjoying it. Very stable and snappy. However, the battery problem is killing the experience. It drained fro. 69% to dead in 6 hours overnight! Switched from 1.1 because the phone got very laggy and the hand off between 3-4g was getting dropped and I was losing data connection.
I will try the battery saver app. Just got battery calibrated and still not any better. My need to have a phone that doesn't suck will keep me playing with this thing until I get it right. My Charge is used so much it's like my third hand.

Did you try to disable(freeze) SDM app and also Google service? May need to backup all your apps and do a factory/data reset, If not help, possible to re ODIN factory image (see pos # 5) since you have data drop issue. Some thing is mess up in your OS.
For betterbatterystats look at wakelock and see what process used the most.
If it died overnight then something is definitely eating your battery. Are you in a low signal environment? Go to settings, about phone, then battery usage. If anything besides display is taking more than around 5-10% (can be more if you use it a lot) then that's your main problem. If your cell standby is more than 25% it's the low signal that's killing the battery.

Data is up and running smooth after flashing newest tweakstock. My home has a strong signal and my bedroom is sometimes 4G so I don't believe the signal was low, unless the transition between radios killed it. However, it wasn't a problem 3 weeks ago.
I did freeze SDM and noticed some improvement. Buhohitr, did you mean freeze Google services framework?
Battery usage seems to be normal for now. I am noticing Dolphin is no Singer sucking down 35% or more since I switched to Mini. It doesn't even show up on the list.
I'll see how it goes today and report back on wakelocks. If it doesn't get any Beyer ima Odin to stock and root/flash tweakstock again.
Also, the battery doesn't drain unusually fast wile in use, browsing, music, etc. But when it sits it drains at 3-4% an hour.
I would try manually calibrating your battery. It really worked for me. On average I get about 18-19 hours on one charge with medium to heavy data usage throughout the day. There is a thread in the General section.. I'll post a link in a little bit.

Wiping battery stats is a complete placebo. All the battery stats stores is the state of apps as related to various things that affect battery life (like display on time, screen brightness over time, and wakelock states). It does nothing that will actually affect your battery life one iota. It is actually cleared every time you charge your battery to 100%, so manually wiping it is completely pointless.

I'm well aware of the post of Dianne Hackborn debunking the myth of wiping the battery stats; however, if you actually read the post on the steps to calibrating your battery, it's not just wiping your battery stats. There's actually a few more steps involved. You're right though, if you just wipe the battery stats and expect better battery life you're just wasting your time.

To disable Google Service, go to settings -> location&security and uncheck Google service. Do not freeze Google framework. Also seems like your phone is not in deep sleep, please install "battery saver" by Antutu and let it works for 24 hrs, you should see huge different when your phone is sleeping. BTW what kernel are you using? If you're using PBJ kernel you can install "CPU tuner" to further keep your phone in deep sleep. I'm talking about 1% for 3 hrs sleeping.
I'm curious as to what Battery Saver actually does. The app's market page doesn't say. I'd be curious if it would interfere with my IMAP push email or SetCPU's overclock settings.

I've done that and never seen an actual difference. Like I said before, I have no reason to believe that any of it is anything other than placebo. My normal daily variability in use is more than enough to account for any perceived differences. On top of it all, bump charging is not good for a Li-Ion battery, so if anything, those instructions are a good example of how to lose long-term battery life for short term gain.

Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.
I rooted my Sensation 4G for the first time yesterday, and was pretty happy with how smoothly everything went. However, I noticed during normal use today that the battery was being drained faster than usual. It dropped by about %20 within a two hour period - much faster use than during pre-root. I checked things that might have been draining it. But I found nothing new that could've been considered a possible culprit. I'm running the stock rom with Go Launcher EX. Has anyone else experienced this phenomenon after rooting?
Not without flashing a custom rom, and even that's a rarity. Rooting in general does not cause much extra to be run, so battery is virtually unaffected. Try fully discharging the battery and charging it back up to 100% without interruptions during the recharge. That usually clears up battery issues.
A better idea is to completely charge the battery until it is 100% and the led light turns green. Then while the phone is still plugged in go to your recovery menu and wipe the battery stats. This is not a recommended process, its a REQUIRED process every time you switch roms. That should fix the battery issues that you are having.
Thanks, I'll give that a try when this drains out. I also noticed that more RAM is being used now after rooting, which looks to be the result of too many apps opening in the background. It's strange that this didn't happen before either. I'm hoping something didn't go wrong in the rooting process that caused this.

Are you using many apps that require root permission? And the battery stats is only reccomended, some people say its a myth and don't bother, but do it once for every new rom. And give it a few full discharge and recharge cycles before deciding the battery drain is high.

I'm only running BatteryCalibration and Titanium Backup that need root permissions. I'm just seeing more regular apps running now than before. And I've been checking app activity through the Go TaskManager Widget if that means anything. I'll take the advice and calibrate the battery after it's at %100 and give it some time, although I didn't change ROMs yet. Would flashing a ROM and then calibrating have any possible effect on this?

Task managers tend to cause more harm than good, they're okay to monitor but killing apps all the time drains battery. As far as ram usage goes, a good custom rom will work wonders, and depending on which one you pick, the battery should improve too, but as far as calibrating goes its the same on any rom. Most recomend wipes.
When charging to 100% I highly reccomend using an app called current widget, because the battery is out of calibration it won't show an accurate full battery if it won't show an accurate draining one. So use current widget and charge overnight, or as long as you can, leave the phone locked as much as possible and check the mA value every now and then, and even if the phone says 100% wait til the mA reads close to 0, mine usually doesn't show less than 15mA after an overnight charge. Then wipe stats.
Sorry for the essay but I've read a lot about this and current widget seems to be the best tool I've found.

My phone has been acting really weird the last few day. I had [ROM][MTD]CyanogenMod 9.0.0-rc2 UNOFFICIAL by TeamAcid[R5][Jul-20-2012 installed on my phone. But it would crash all of the time. Afterwards when the phone rebooted the battery would go from 100% to 9%. If I dont boot the phone back up right after a crash and wait a little while. When I boot it up the battery will be around 40-45%. I used [Heimdall][One-Click] The T959V Heimdall One-Click Collection [05/20/2012] earlier today, Just to see if I continued to have the battery problem. I only had the phone crash once while on the stock rom, and the battery did drain about 50% but I also started having a problem where I would lose my data connection all together. Rebooting the phone brought it back, only to lose it again after around 30min to 1hr. It has not crashed for about 3hrs now and I have not lost my data connection either. Anyone have any ideas what might be going on here? I tried deleting the battery stats with the battery at 100% before going back to stock but that did not seem to help at all. I downloaded a batter calibrator from the market place and tried that as well. Used it when the battery was at 100%. None of this has worked. Now that im back on the stock rom its only crashed once, but the battery did still drain. Any ideas? I would really like to go back to CyanogenMod 9 but its not worth it if the phone continuously crashes and kills the battery. Any help would be greatly appreciated.
Try Gremlins Remover.

So you don't waste any more time, "battery calibration" is snake oil, lithium ion batteries don't need "conditioning" (and actually suffer from both high temperatures and deep discharge cycles), but the moon is made of cheese. Ok, at least the first two are true.
As you're having problems with one of the most stable and reliable GB ROMs for this phone, I suspect that you may have one or more of:
Bad battery
Bad user-land applications
Corrupt application data
Corrupt media data (for example, music on your microSD)
Bad phone
Bad luck
A "start over" approach with a complete clean-out either using the above-mentioned one-click, or doing the equivalent by hand (wiping all partitions, flashing stock, starting with a fresh microSD), then seeing how the phone/battery behaves without any apps would be the path I would take. If it passed that, I'd slowly start adding back apps, and only restoring data/preferences where you really need them.
Im doing the gremlin remover right now. I will let you guys know how to goes. Thanks for the advise, this has been driving me crazy.
Tried the gremlin remover last night and played with my phone today. Its still crashing and then when I boot it up back the battery is pretty much dead... I think i have a bad battery. Never had these problems with the phone before. Thanks for the help guys. I guess Ill get a new battery and see if that fixes the problem.
I have this EXACT same problem. I'm on AOKP and the battery with go from having a decent charge and die. Then if I take the batt out, hold the power button for 15 secs and let the phone sit with no batt for 10 minutes or so, the phone will go back to around 50% batt life. After gremlin remover and Bryan's one click back to stock multiple times, I've finally come to the conclusion that I need a new battery.
I ordered a new battery today. I will let you know how it goes.

So I looked I to this issue more. For anyone having this problem, remove the battery and place it on a hard flat surface to see if it has swollen any, if it has then the battery is defective. My battery actually rocks a little. I could actually tell it had swollen before I even put it on my desk.
That is only for seeing whether a cell has busted. It is normal wear and tear. That is kind of like how u lose battery life after hundreds of cycles because it is just how the current li-ion battery technologies work.
I would download the one click and also reflash boot loaders and repartition your device.

thats crazy swapping you battery worked. lol, mine does it too. not so much the crashing just a simple reboot and it will be drop down from 70% to 1%. This was doing the same thing with my phone before my charging port got busted. So i had to swap out the guts from my old galaxy s with broken screen. When i put the new internals in i started with bh's one click back to stock and flashed antonx kernal. Then flashed cm9 and it still does it. i will try a new battery as well.
My thought (AFTER being solved)
Well, I don't mean to come off as rude, but come on guys! I've had this problem for a while, and as soon as it happened I knew I needed a new battery. On top of my phone being somewhat "old", the fact we all play around with it so much, and do so many battery pulls most likely does NOT help the matter. At least I screw around with my phone and try out many ROMs...
But I'm glad I have confirmation that a battery swap will do the trick. It sucks that stores don't carry the t959v battery anymore... Guess I'll be ordering online tonight.
hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?
Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn
ahh ok thanks guys ill do what you guys said and see if it helps
you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.
no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.
If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

.... If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.
I'm having issues of the phone rebooting by itself and consequently draining ~90% of the battery when it does so. I've tried flashing a bunch of different ROMS to see if I can stop it from happening, but to no avail. I'd like to go completely from scratch and hopefully I can get to a point where the phone works for an entire day without crashing. I've been using the HD2 instead of the SGS4G for a couple months now, so I'm a bit rusty, which is why I came here to ask for suggestions. This is what I was planning on doing:
- Flash one of these stock ROMs in order to get back to where I started.
- Format my SD card completely and let the phone convert it back to EXT4
- And then flash either Barebone or Valhalla
Do you guys think this would be sufficient enough to remove the problem that's causing these reboot & battery drains?
I would flash eollies kj6 with the blastoff v2 if your not planning on going to ics after because that's the latest gb kernel available and then flash Valhalla or barebones (then you might have to flash blastoff again can't remember right now but it should say in the op of each rom). And I'm pretty sure when you one click back to gb that will convert back ext4 so I would format SD card and reload it before you one click back. Good luck friend

Thanks for your input! Do you think the gremlin remover is necessary, or is it overkill in the context of what I'm doing?
If you want quick and easy use my one click the other two listed is just kernels.
As for getting battery life on ICS flavored roms, well take the time using BBS and STT to figure out whats killing your battery. As long as Im not jumping between wifi and mobile data I can go around 15 hours on a battery. And I havent spent tons of time to figure out why Im not getting more battery life. But others like jeffsf has. And with that I can honestly say if your not getting battery life comparable to GB roms its YOUR fault not the rom. Most ICS roms have stuff built in that you have to use a app for. Therefore a GB rom with nothing installed will get better battery life. But once you put your stuff on and start running the battery life is not being compared properly. The reason for this is most people will keep a app just because they are use to it and not even know the ICS rom has it built in.
I personally think most of our batteries - if still using the one that came with the phone - are starting to run their course. New batteries are inexpensive on Amazon.
I think you guys are misunderstanding my issue. My problem isn't the battery draining quickly over a certain amount of time due to regular use. My problem is that once my phone crashes and reboots, the battery will literally go from whatever percentage I was at, all the way down to below 10%. I can be at 90% battery, and if my phone crashes, it will be on low battery once it powers back up. I'm not sure what's causing the crashes, which is why I'm just trying to start at step 1 and work my way from there.
To test if it was the battery simply draining out very quickly, I turned brightness to 100% and turned WiFi & GPS on, and disallowed the screen from turning off. The battery drained normally.
That happens to me... It gets fixed by shutting down and taking out the battery for 30 seconds.
Sounds like a bad battery
i had the same issue and also would get diff battery levels when booting with or without charger plugged in...i used a toool from market to calibrate battery. i cant remember exact app but will post back if i find it.
edit:
it was "Battery Calibration"
by NéMa
and i had to do it a couple of times to get it to set in.
Like thecontroller stated its a bug and you should be able to correct it by pulling the battery out and waiting a few extra seconds. If it does it still hold the power button down for a little while with the battery out.
Do this next time you have a crash on ics. Time how long it takes for the phone to restart. It is seems abnormally long you could have some scripts that are running on boot that is causing issues.
Calibrating the battery can be done manually. All you have to do is delete the batterystat.bin file. That is all those apps do. And really If you fully charge your battery it should be deleting itself.

In a nutshell, yes. You are only putting extra stress on your battery by "tricking" it according to various calibration guides. Batterystats.bin file is generated for a reason. Batterystats.bin is in /data partition, so after you install a new ROM that wipes your previous data, it gets wiped too. So, "Wipe battery stats after installing a new ROM", which is a cliche among those guides, is pointless. Last but not least, batterystats file is simply a logging tool that monitors your battery behavior. The "stats" part is pretty self-explanatory. The actual Power Manager lies in kernel, not in /data partition which accessible to anyone.
SBD all that info is true. But if you use the aroma installer it will backup and restore the data partition. Not sure if it will restore the batterystat.bin file or not. That is why I posted what I did. I do not believe in calibrating batteries as much as making sure they file is not storing data that is out of date.
As you guys mentioned earlier ...hard resets are the best ....I find our batteries do go bad. And when they do....they do all kinds of odd things to the device

Battery calibrations are garbage. They do nothing. The file that any battery calibration app deletes is deleted by Android anytime you do a full charge anyway.

Not to mention the screen. Was in Costco last week, saw the old T959V on display and held mine up to it. Screen is faded bad I don't know if any of you else have noticed that lol

Okay, so I formatted my SD card, and flashed Eollie's KJ6 using Heimdall. After that, I flashed Raver's Valhalla Black.
Initially, I didn't install anything extra other than updating gmail and superuser. Everything worked fine, apart from one random reboot. Once it booted back up, everything was normal. Today, I installed around 5 apps. I was using one of those apps (Reddit Is Fun), and while using it, the phone crashed. Once my phone booted back up this time, everything force closed, and log provider force closed over and over. I had someone text me, and right after they did my phone just crashed. I tried fixing permissions, but that didn't do anything.
Any suggestions?
--edit--
I just factory reset and tried reflashing Valhalla Black, but everything just force closes again even on a fresh install.
Boy I don't know what the hell you're doing but you are doing something very wrong.
Flash back to stock (complete stock). http://forum.xda-developers.com/showthread.php?t=1358498
Then flash AntonX http://forum.xda-developers.com/showpost.php?p=19601810&postcount=2
Once you do that, flash a ROM.
I just went through the same issue. This was going on rarely for several weeks then got more frequent. I have a couple of extra batteries that T-Mobile sent me when I first got the phone....swapped in one and its been 10 days without a single issue. Before posting here tonight I put my old battery back in and guess what? Symptoms came back within 30 minutes....so....

Then there's your answer, you need a new battery my friend
Just so weird, I don't see how a battery can affect the OS in that way haha. I've ordered a new battery anyway, they're only like $5 on Amazon, but I'm gonna try your steps anyway, controller. Thanks a lot guys.
