Battery life just terrible, need since help plz!!

As title says guys, I don't no why but my battery life is just really bad since I moved from stock 2.1 Rom to custom ROMs :-(
Is it my phone? I can't work pig wot it is. I checked the battery usage #*#*4636*#*#) and it seems the Android system is using A LOT of it. I tried charging with phone off, clearing battery stats, not overcharging, but just can't resolve this issue.
Also, I have sync set to update manually and have mobile internet off always, only on wen needed. Same with WiFi. Screen is on auto and time off screen lock set to 30 seconds
I am using OpenDesire sense Rom
Any help will be really appreciated.

I could feel WiFi siginal of 2.2 is much better that stock 2.1,
I suppose that the better performance will bring the fast battery drain,
if your custom ROM support WiFi N mode,
that really makes your battery life short that before.

I have the same problem and same settings as you. I read on other forum that people who updated to official 2.2 have even better battery life.
I cant even squeze 20 hours out of my battery :/

You guys should always post what ROMs you are using...

Opendesire 3.3, its the same with defrost.

i also had really bad battery life on those 2 roms
even doing nothing the phone would just keep dropping
go to official froyo 2.2
neophye roms for me have amazing battery life = 48 hrs..

Agree with cygnet

Is there another non sense rom? I really like stock better...

Check if the phone goes to sleep correctly. Spareparts > battery usage: other usage, since last unplugged.
I had the same problem, until I found out that the phone was not going to sleep. (running and screen on percentages were way off. Almost 100% running and a lot less for screen on.

update to the last radio

I found that after forcing everything to install to SD card my battery life plummeted. There were apps/widgets that should have stayed on the phone. Once I moved these back, battery life was back to normal.
I use Systempanel to see the battery drain graph and could see a pattern to it.

Same issue here, Will try Neophyte tonight
Using this rom http://forum.xda-developers.com/showthread.php?t=741663, and it's fantastic! However batt life on .08 and .20 radio is a shocker. I watched a 1 min trailer on youtube, in and out and I lost 4% battery. Before with OpenDesire I'd be shocked if the battery percentage even twitched slightly.

I use Defrost 1.5a and I just use about 2% every hour when the phone is sleeping, and that's with auto sync and mobile data enabled. (disabled it's 1%/hour)
Always underclock to the lowest mhz when the screen is off using SetCPU and when you do use your phone make sure the brightness isn't too high.
I could make a whole list of tips, but I'm sure you'll find more than enough of those on the net.

I may be dumb but how do you force your phone to go into sleep once screen is turned off ?

(using Cyanogenmod 6)
When your screen is off, your phone should automatically go to sleep. Sometimes widgets or apps keep this from happening (like the music player), making it use battery as if you are constantly working on it.
How I resolved this issue was to find out what app or widget caused this. I ended up starting from a fresh reset, installing first all apps I really use (calendar/message widgets, powerstrip etc.)
I tested by installing an app, rebooting (or sometimes not), check the running time of the phone, turning screen off, and check again in 5 minutes. The phone should go to sleep in about 30 - 40 seconds. I am telling you this, because most apps causing this are widgets/apps running constantly.
However, I found in spareparts also that 'settings' was taking alot of usage time in usage statistics. A simple reboot did the trick from here on. But I am guessing I had installed something which made some app not close properly..
Maybe it is better to have a task manager/killer for these situations.
Running and Screen On percentages should not have too much of a difference if your testing and not using the phone while screen is off (music, bg stuff)

You could try juicedefender, it helps improve battery life by disabling unneeded connections while the phone is not in use

[Q] Questions about CyanogenMod, and general battery life

Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?

Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

I had the same problem with my Bluetooth recently. When I try to search for devices the phone locks up and I have to pull the battery. Wonder if this is a kernel issue. I am on snap

Yep, I'm on Snap too; must be it.

Another thing; I've got a friend on Stock 2.2 Sense (battery sucking widgets filling the home screen, etc) with 100% brightness and mobile data constantly on and he gets better battery life than me (20+ hours!) What is going on!?!?!

Epic 4g not sleeping properly any suggestions?

I'm running the SupernovaROM and when I go into spare parts...my time without sleeping isn't at 100%....but It never fails that it gradually always creeps farthr and farther away from the screen time on number...it might start off (time without sleeping & Time with screen on) 1 or 2% apart..and by the end of the day its almost double..and this is consistant.
I've tried clearing the dalvic and regular cahes...I even fix the permissions in CWM 3....its fine for a couple days but the problem always creeps back...don't know what else I can do?

What you do is when you notice that it's doubled on the top drop down box that says "other usage" click on that and change it to "partial wake usage" and anything listed under there is keeping your phone awake. See what is continually running.

Thank you...I saw that facebook was running for an extra amount of time...and I also saw that "android system" was running a little extra..what could that be? (Besides the obvious) could it be a problem with the radio or something along those lines?
sent from my rooted, suited & booted Epic 4G know dat

I actually had a ton of trouble with this, but not on CW3. My problem was different, but I still want to talk about it. No matter what I did or what rom (including the stock), my time for not sleeping would reach 80% to 90%. I even tried without any applications installed. Sometimes this would even happen with the radio turned off. I finally fixed it within the last week.
My problem was fixed when I flashed EXT4 and midNIGHT rom v2.9. Now, my phone always sleeps. By the end of the day, the time without sleep I about 15%. Depending on usage, I have 40% to 60% battery life remaining after 16 or 17 hours. This is with push gmail, exchange, and gps turned on.
Maybe there was some glitch on my phone that wasn't being wiped in CW that was cleared when my file system was converted.
Good luck!

I really appreciate the help...only bad thing is I'm lready converted to EXT4 with CWM3....and I used to have the same issue with the sleep time being 80+ no matter the apps, I switched to Froyo and now the problm is more subtle with respect to the screen on and time WO sleeping %'s...they just crawl away from each other...I'm on supernova ROM 1.5...and I might have to take a look at that midNIGHT Rom....I have the Emotionless beast theme and I move around allot of Apk files through root explorer...(everything is compatable and works BTW).
But anyway I'll try that ROM out and see if I can get my Epic running as smooth as youres thanks again mane!

stock 2.1 idle drain

So...I'm using 2.1 and for some reason when I'm not even using the phoone..the battery drain is ridiculous. Since I'm new to 2.1, does anyone know what is causing this? Any processes I need to end? Any thing I need to remove?
I'm straight up rooted stock 2.1. No custom roms, just a custom kernel. I only downloaded Pandora, Wordfeud and SetCPU.
Edit: I also wanna add that I leave on 4G as well and I see it idle out and when I turn it off and leave it off I still experience the same amount of drain so I dont think its 4G.
And for more details on the drain...I went to sleep for about 3 hours and during that time I went from 91 to 42.
Edit2: Im gonna actually see if maybe it was just the kernel...I was using the first version of a kernel, not its latest version so Im going to put on the latest. But still, Id liike to know if it was a common problem and how most people fixed it.

Kill the omadrm process with each phone reboot. (Forgot exact name, but that is close) If you aren't always in a 4g area, having that radio always on will drain the battery.
Sent from my SPH-D700 using XDA App
Edit: Also double check your phone standby time and see what percentage your Time Without Signal (TWS) is at. Toggle Airplane mode after each reboot will correct that bug.

Also fyi you can use Tasker to toggle airplane mode for you automatically every boot

Type this into your dialer:

Click battery history, then click where it says Other usage, change to Partial wake usage, this should tell you what is using your battery while its asleep.

It you can just.install spare parts and.look. also check your time without signal. If you don't reset your radio its prolly 50%. Whether.that is.cosmetic or actually does cause a battery drain its still good to do.

Battery life even with removing a few apps is pretty bad.
I think the most I got after a week of tests was about 18 hours and that was with almost no use.
Try downloading JuiceDefender from the market. It's free. What it does really is enable/disable your 3G/4G/WiFi connection when your phone is not in use. It also enables it every 15 minutes (default setting) to get email other updates such as weather. I am not kidding when I say went from an 18 hours to 72 hours hours. Granted, that was with little use.
Can download JuicePlotter as well to get an idea of how your battery is dropping and holding.
Side note that WordFeud constantly runs in the background, so that WILL rape your battery. JuiceDefender will keep it in check. Best app I ever got.
For reference, under 2.1 with JuiceDefender I would lose only about 1%/hour at night when I was sleeping.
Under 2.2 it's more like 2% per hour >.> and I've yet to figure out what's draining it.

I thought I'd chime in since the OP mentioned Pandora. After installing Pandora I noticed my battery drain had gotten significantly worse even when properly quitting out of the app. After uninstalling Pandora battery drain has normalized to the way it was before.

Also, setting your network to sprint only helps with battery too.

maybe where you live it does, but thats an awful idea if you are in a town with little service because it will spend more time searching for service because it can't roam (i live in the middle of nowhere in new hampshire).
instead try to update your PRL. download the SDX stock app removal apk. remove the drm crap. and reboot. then charge your phone all the way, reboot into cwm, and reset your battery stats. then let the battery drain all the way and recharge. that should improve it significantly. thats what i did and it worked pretty damn well. battery life is upwards of 36 hours nominal charge now. and my phone used to drain battery WHILE i was charging it if i used it at all. and that was with a 1 Amp charger. also dont let your battery overcharge, mine seems to drain easier when i leave it plugged in all night.

Battery drain is ridiculous...please help

My battery is draining like CRAZY and i cant seem to find out what the issue is. Ive tried calibration several times and using a task manager that turns off running apps every few seconds(which seemed to make it worse) and that didn't help. Auto updates are turned off and fbook is only set to update every hour and brightness is set to minimum yet my battery only seem to last 8hrs. please help. i would really like to pinpoint what the issue is.
Oh...im running ERA Legendary 2.1, CPU speed and voltages are stock

That screenshot is worthless. It doesn't show anything useful. Percentages are meaningless. Get Betterbatterystats to see what is running as far as processes and partial wakes. Get CPUspy. To make sure your phone is going into deep sleep. Get Memory Booster Lite to see what is using your battery and get rid of the auto task killer. That will kill your battery fast.

i only posted the screen shot to show the time vs percentage. i already got rid of the task killer and here is a screenshot from better battery stats. idk how to stop the processes though...

Again the percentages mean nothing. In Gingerbread everything goes through Android system so it will always be highest. If you use your phone only an hour or two a day then it will drop to around 60% with cell standby getting higher. They will always add up to 100% whether on a minute or 10 hours.
You didn't post the partial wake locks screen. Also did you check CPUspy for deep sleep? Did you uninstall the autokiller? You can go into settings>applications>running services and stop applications that shouldn't be running like Facebook or music and video players, etc. Sometimes it's best to get an app like Bloat freezer and freeze apps that keep reloading if you don't use them often.

Another question and maybe the most important...what is your screen on time? I didn't see it in the screen shots. I think Max screen on Time I have gotten is right around 4hours. All the battery tweaks in the world wont help, if your screen is on a lot. Also...make sure to freeze drm, sns and system updates. Use randomlking's zip file.
If none of that works...wash, rinse, repeat. Wipe clean and reflash, rom and kernel.

As I'm sure you know, everyone's battery drainage is widely independent. However; I'm on "stock" Legendary 2.1 and recently with the updated Samurai kernel as well and run Juice Defender Ultimate. I've got some advance settings set but over the past 3-4 days, I average about 20 to 22 hours on a single charge.
My usage in an average day is: about 20-30 texts, about 10 minutes of phone calls, 10-12 emails in and out, 10 minutes of web, whatever app updates there may be and maybe about 15-30 minutes of light to medium use games.
If JDU is something you might want to look into, I would be more than willing to post my setup to get you started. <--For some reason, people are real stingy with their JDU settings.

This kinda thing just happens sometimes, and usually clears up on it's own. Especially common after flashing new software.
