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.
Thanks

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

"Android OS" Eating All my battery!

I have the CDMA Desire. I am running Cyanogen 7 Nightly.
Even on older Cyanogen ROMS (6.1.1) I always had the issue of Android OS taking up my battery. I looked at my phone when i woke up to see it was at 11% even though it was idle all night AND fully charged when i went to sleep. Don't know the problem. Perhaps somebody could point me to a battery efficient kernel? Or help me solve the issue

If you barley use the phone it's logic that the android os will take most of the battery. Do you use taskkillers? If yes, don't.
And about your drain, do you have the wifi sleep policy set to never?
settings-wireless and network-wifi settings-hit menu-advanced-wifi sleep

Task killers? No, they are really more of a myth than anything!
Wifi Sleep Policy is set to when screen turns off.
I also forgot to mention in the first post that it took up 77% of the phone's battery.

I hate to bump, but bump.
I switched launchers to see if that would help, i'll update when i find out

Maybe this?
http://code.google.com/p/android/issues/detail?id=11126
Also, check for programs in the background which are using a lot of CPU (like OS Monitor from the market).
Make sure you wifi sleep policy is set to NEVER! (Under settings > Wireless & Networks > WiFI settings > Advanced

Faulty battery?

one thing i noticed with my own battery drain is that i had my tweetdeck updating every 15mins, prehaps you have things that are sync all the time?
also i saw in a post somewhere in XDA that it is just how the batteries work, the lower battery charge you have the faster it will run out.

Widgets? System info widget literally wasted my battery even when not used. Removed and happy about it. Shame you don't get a refund
Check your widgets in the market if there are users complaining about them.

Cell standby will _always_ use more if the OS is operating normally.

I try to keep my phone from using too much stuff in the background. I have Pulse, Twitter and Google Maps (can't stop it) in the background at all times and can get 2 days usage out of it. Widgets and apps running in the background usually are the culprit but if you haven't got a lot of stuff running in the background then I would say faulty battery.

battery life

Ok so ive installed alot of custom roms on my wildfire s and on all of them my battery life sucks. If im on wifi my battery goes down 10 to 15% in like 2 to 3 minuets. Do you guys think its because of the roms or i just need a new battery. Please help.

Type in the call menu : *#*#4636#*#* and go to battery menu.Wrote there all the informations.
Do you full charge your phone ?(about 2-3 hours)
Try to delete the batterystats.bin file via CWM.
If i helped you,click "Thank's" button.Have a nice day

10 - 15 % in 2 minutes? WTF?
Are you sure your battery isn't faulty?
Even in worst conditions my battery never drained that fast.
Anyways here are some tips:
-Charge phone to 100%
Go to CWM and delete battery stats.
- Dial: *#*#4636#*#*
Go to phone information, In preffered network type Select GSM auto PRL.
- Use juice defender or something which would turn off wifi whenever its not being used.
- Make sure all the accounts aren't set to push as it takes a lot of battery.
- End processes by going to Apps-> Running services.
- Don't use heavy widgets on homescreen or launchers.
- Brightness to auto and timeout time must be less.
I could remember just these. But I guess if it's true that your battery is draining that fast most probably your battery is faulty. Get a new one.

sounds like a faulty battery.

Kill/Uninstall Apps
Yeah, I had this problem :/
What I did was
- download a battery saver app, It closes mobile networks when you're not using them.
- Set the screen to a low but visible setting
- Uninstall some of the memory draining apps
- and kill some of the RAM munching apps.
Hope this works :L

ill try some of them

Don't download a battery saver app, it'll just use cpu cycles and battery even more.
Manually turn off mobile data and wifi when you're not using them.
Don't overclock.
Lower your screen brightness.
And ultimate solution, get an extended battery.
-----------
"You can overclock as much as you want, your phone will always seem too slow."

What kind of charger are you using to charge the battery? If the charger's voltage and Amp's out put is higher then what the phone can take it could be over charging your phone and charging your phone way to fast. If your charger is normal then I would invest in a new battery, a o.e.m battery is good.

[XS] Appalling battery life

I'm currently running 4.1.2 stock, rooted. With Locked BL. The battery drain has been absolutely shocking. Help

Download from play store this app: Du Battery Saver&Switch Widget! I have this app since last week and it really works...

People in here are right. Greenify it's more than enough. But also Du Battery Saver can do the trick, what's great about it is that is lowering your CPU frequency when screenlock, so try them out.

Use screen settings as low as possible. Trust me, thats the main cause of fast battery drain.
Use Lux auto brighteness. Its a good app.
Next one , use titanium backup to freeze the app that you are not using. Its always a good to freeze app, so it wont run in the background and u can save RAM.
Use greenify. Thats the best app for hibernating the apps. That way both battery and RAM is saved.
And use DU battery Saver , thats also an awesome app. in which u can set the phone to change your profile on time basis, and lower frequency of cpu when screen is locked so battery is saved.
Hope u got some ways to prevent battery drain to a limit

Those apps are all great, but why have a HD Screen phone when you have to lower the screen brightness to a minimum, that sucks.

It's very simple, at du battery select saver at the bottom and create your own custom mode!

Thank you all for the responses, I will try out all the suggested apps and get back to you all. Thank you!

Keep the brightness around 35%. I find it perfect for indoors. Your screen on time should be atleast between 2:30 to 3 hrs on average.
Use darker wallpapers
And underclock to 1.2ghz or something if you dont use resource hungry apps. Use conservative governor and noop scheduler.

Trinity ROM
Screen brightness at 35%
Stamina mode on
Using greenify
Only 2G networks
Moderate Wi-Fi usage
Default CPU frequencies

Also, don't use battery savers like go battery saver and battery doctor, they only turn down brightness and data networks, alot of them don't have a great effect in battery life. Use apps that freeze/hibernate apps like greenify and snapdragomln battery guru.

so i did realise that you had your screen on alot of the time.... that is generaly 1 reason why , i can watch 8 hours straight of movies on my XS where as on a stock rom about 3 hours , so the XS battery realy depends
list
sometimes the battery will just need to be used normaly just so it can calibrate its self (some weird reason not using my XS for 2 days fixed my battery issues)
i suggest checking if there are any apps that run in the background, just remove them if you dont need them (could prevent your XS from sleeping and also a posible overheat)
I also suggest making sure that your brightness isnt too high, (obviess)
the more you use your XS the shorter the battery lasts day by day, it is nessicary to not use your xs too much as it will take a few days for the life to go back to normal ,(like i said i had a simular issue)

I can see a strange behavior of Mediaserver process. It consumes too much battery. Usually it points to the problem with scanning your media files.
You can use BetterBatteryStats to find out the cause of it.

[Q] Battery not great

hi. im a brand new rooter. i got a preowned s4 mini last week and decided to root it using a guide here(im very new to all of this) i deleted bloatware and use apps like greenify, setcpu, wakelock detector all to my knowledge have been done right and im still having crap battery times. worse than my 5 year old iphone 4s!
i can post any screenshot of stats upon request but from my new knowledge of all of these apps and rooting, i see nothing out of the ordinary. if im being honest, "battery doctor" seems to be a nusiance to my battery. but it often gives me reminders that my phone is draining quickly with 29 apps open that i cant delete with app master or even see on greenify. some of them are..favourite contacts, active apps manager, s planner widget, csc, remote controls, factory mode, alarm and video player. the rest are the ones above like setcpu, greenify etc.
so im asking..what now? ive seen mentioned that getting rid of touchwiz and installing a new ROM like cyanogenmodgod. but what then?
ive no idea how to understand some of this but im fine with following instructions with technical stuff i.e rooting my phone in the first place.
i really hope i can be helped as im really liking my first android experience bar battery life

ill do that later when ive spare time. ill write a little update for now..
tried CM11, simply did not like the UI, i much prefare the stock s4 mini UI (touchwiz?) so ive reverted back. ill be sure to post screenshots of wakelock, battery screen etc.
my signal is rarely above 2 bars if 2 at all..ive changed the settings from LTE to the one that means 3g...hopefully the more stable 2..sometimes full bars saves battery!

heres screenshots of various things.
notice how battery doctor has many aps as being in the backround even though i greenified them AND turned permissions like "always on" to OFF so there isnt a reason why they should be on.
ok..i cant post links until i reach 10 posts so ill add in a space in the link..

If you go to settings > Battery > Battery graph , does it show the phone actually sleeps? (the "awake" bar)
I attached a screenshot , if the bar is compleatly highlighted , this means the phone does not go in sleep.
If this is not the case , i suspect something is wrong with you battery.

nope..the awake bar does have bits missing (being asleep, right?) i seem to be getting acceptable charge times as of late..some games make the phone very warm and do destroy battery % but so did them games on my iphone 4s. this phone isnt brand new..it is almost new..im "happy" with the battery times now but not so much as i expected better times than my 4s but its about the same at best. i may try an OEM battery someday and see if that gives me even a 10% increase.
any advice on charging? took me about 2.5 hours to fully charge..about 1.5 of them hours, i had the phone turned off..the rest was on airplane mode

That indeed means the phone is sleeping.
What kind of Screen on time are you getting ? do you leave bluetooth / 3G / Wifi on all the time ?
3G and especially 4G is a huge battery killer.
EDIT
About the charging , i generally just charge my phone at night functioning as a clock since the battery lasts me a full day.

i have wifi only on. its on most of the day, i turn it off while i sleep or if im out and about with no hotspots about.
i seen on youtube something about a faster touchwiz thats available here..it apparently helps battery life?
also nova launcher may help with battery life too?

Other launchers probably won't help with battery life.
I'd suggest turning off any radio's you don't use and (off course) keep the brightness low. What kind of screen on time are you getting ? (Settings > battery > screen )
