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 ?

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

Battery life is horrible, yet not much is running?

I have my cpu settings on 245 245 powersave when the screen is off, yet I'm still getting horrible battery. I use my phone extremely lightly, maybe once in a while to listen to music. Check my emails, chat every so often. I use to get 48 hours with light usage. Seems I cant figure what is causing my battery to drain. I have a craigslist app, I had one search enabled so I deleted that to see how much it will effect. Does google talk drain that much? In the past it was fine. My usage shows the 2 main ones are cell standby and phone idle. Any tips on finding out what exactly is draining my battery? Im running CM 7.0.2??, latest stable, forgot. Koni's was the same. I thought maybe sense drained the battery, but it doesnt seem to be the problem.

Click the link in my sig and run that battery conditioning routine for one. What kernel are you using?
And dump SetCPU. Useless app, seriously...

1. Update to the latest stable version...7.0.3.1 released this morning.
2. Google talk could be draining, but I've never used it
3. Perhaps install it under a clean install and see if that helps.

Get tge system panel app. It'll show you what apps and everything that's eating your battery. Does the kernal your on perflock unlocked for over /under clocking cause if it isn't setcpu doesn't work.

+1 SetCPU is great for Sense ROMs, but not necessary for CM based ROMs.

looks to me like you were in pretty crappy coverage. that makes the phone work hard. it's justifiable that you'll have a lot of battery drain then, even while sleeping.
you can greatly reduce this by:
1: upgrade to newest cm7
2: flash a custom kernel. may i reccomend tiamat 4.0.1?
3: put your governer on smartass, and uninstall setcpu. smartass does it better.
4: use a bsm from viperboy. they decrease voltages. work almost too well.
5: USE JUICEDEFENDER! this will save a ton of battery in low coverage, because it turns off 3g when screen is off. this still lets you get calls and texts, but with mobile data off, your battery will last much longer while sleeping.

what prl are you on?

[Q] How to get longer battery life on Deck's gingerbread-evo-deck 1.2.1 Rom

I was wondering is someone can help me. I've been using Deck's ROM's for the HTC EVO 4G for some time now and I hear about all these guys getting 20-30 hrs of battery life. I'm currently on 1.2.1 and have never got probably more then 11 hours out of my battery life with heavy or mederate usage. I've updated all my radios, wimax, etc....I've tried different kernels, I've installed vipermod and undervolted, I have CPU profiles. I've installed a new 3F3D driver. I've tried the wake lock fixes and still nothing has changed. Am I missing something here to how these other guys can get that performance out of their batterys. I'd like to post this directly to his thread but this is my first post and I guess I need at least 10 posts. I'm a bit of a noob but can hold my own.

I run decks with tiamat kernel 4.0.5 and I get outstanding battery life. Give this a try then let me know how it works out. Check your accounts to see if anything is synching that's insignificant. Then check your apps update frequencies. Lastly, turn off all of the haptic feedbacks, animations, and effects. Live wallpapers kill a lot of battery too. You might also want to try enabling and disabling auto brightness to see which is more energy efficient. If your overall goal is great battery life, then a lot of the bells & whistles are pointless.
It is nice to be important, but it is more important to be nice.

I've tried tiamat 3.3.7, 4.0.5, and 4.0.6 and have got the same results with all three. I've tested each and one of these over about a week period. Currently I am trying SavagedZen 2.2.1 and up til this morning it hasn't changed much. I've took off all auto syncs. All haptic feedbacks, animations, and effects have been turned off. Never use live wallpapers and have read that lighter wallpapers will conserve battery. Right now I have auto brightness off and down to about 35-40%. I did however just checked off data enabled about 2 hrs ago and seem to have got better battery since. So far I'm at 82% with about 4 hours of moderate use. (mostly texting and surfing the web). I didn't know if there was any other tweaks internally that I'm missing or if it's more of a puzzle with what combinations to use.

Just saw my background data was enabled. I unchecked that as well. We will see how this goes I guess.

It seems like it's definitely data related. I downloaded skype from one of the forums strait to the phone and my battery percentage went from 79% to 68% just for the duration of the download. Is this common?

Do you use an SBC kernel? Have you whipped battery stats in recovery? Have you tried using the kernel governors (smartass, powersave, conservative) without setcpu?

I have used kernels with SBC and without and haven't seen much difference besides the initial 10% loss of battery. I usually I wipe cache, Dalvik cache, and battery stats everytime I flash a new ROM in recovery. I usually do a factory restore too. I've used smartass and savaged zen as governers as well. Currently I'm using savagedzen governer with a max at 1036 and a min at 245. I also calibrate the battery when i flash a new ROM. Currently I'm standing at 60% battery with about 7hrs and 37 min on battery. Probably the best battery life I've seen. I'm still seeing massive drains when I use 3G. I was just on xda forums on my phone for about 5 min. and the battery went from 65% to 60%. If I turn 3G off it stands idle for awhile.

I'm scratching my head trying to think of what will help. You probably won't like this, but when my rom has me stumped with a problem, I wipe and start over. Maybe an extended battery is the answer? They are dirt cheap for the EVO now.
It is nice to be important, but it is more important to be nice.

Yea I was thinking about an extended battery as well. It seems like taking 3G off does wonders for the battery. Are you keeping yours on or off to get great battery life?

Lowering your max and min cpu frequencies will improve your battery life. I've always used 128 MHz as a min with no ill effects. Ever since I got my evo I've kept the max at 998 MHz and it was plenty fast, but I am currently trying out 691 MHz max and it seems just as snappy so far (battery life was great at 998 MHz max for low or moderate usage, but with heavy usage I've noticed it drains too fast). I'll probably try out some lower max frequencies to see how low I can go without affecting performance.

Use JuiceDefender to automatically toggle your data connection (3g/1x) off when the screen is off. This will dramatically improve your battery life especially when you're in areas with poor signal. If you want, you can set it to turn on the data connection at user-defined intervals so emails, google voice, and anything else that needs a data connection to be refreshed periodically can go through. With the paid version, you can even allow exceptions for programs like google music, pandora, or wireless tether, so they can keep the connection while the screen is off if they're in use.

Ill try juicedefender. I had it before but didn't really know what settings to use. Current battery is doing well. I'm curious to if all these people experiencing 20-30 hrs of battery life have data turned off a alot. I'm currently at about 14 hrs. with about 42 percent left. Thanks for all ur advice.

I can easily get over 40 hours with light usage and over 20 hours with moderate usage, but that's only because of JuiceDefender. Without it, my battery drains like crazy at work where there's really bad reception.
I use the customize profile with mobile data enabled, schedule enabled at a frequency of 30 min, and apps enabled when the screen is off for google music, pandora, and wireless tether. I also enable the text notification which puts the icon in the status bar. I've run into problems when I disabled notification where JD gets shut down in low memory situations, but having the icon in the status bar prevents that. I leave wifi, location, and night mode diabled, but that's just because they're not useful for my usage. I'm sure the other profiles work fine as well, but I just like knowing and controlling exactly what JD is going to do.

Try using saveged Zen with conservative governer, viper mod and other little things people have mentioned

I'm going to run JD all day today with those settings to see what it does for battery life with my data on. Yesterday seemed to be the best battery life I've recieved with data off for the majority of the day. Got about 17 hrs with 39% left. I'm happy with that. If JD can get me something like that without having to toggle with data on/off that will be nice.

I've run viper mod with tiamat before and undervolted 50mv with little or no change in the overall performance of the battery. Any suggested settings for savaged zen using viper mod?

Undervolt as much as you can, all phones are different. As for jd, sorry I forgot about that. It's a HUGE improvement. Your battery can pretty much double. It can be a little annoying in some cases.

Didn't really get to do a full trial on battery life yesterday. I downloaded a Sense Rom and tried some troubleshooting that I read on Deck's page but it didn't work. Today will be the first full day I try JD with 3G on. I will probably try viiper mod tomorrow after the results I get for today. Thank for the help guys.

You can't judge in one day.. you have to wait like 3 days of use to let it settle down
Deck's + SZ + SuperCharger script + ViperMod script.

I believe I have found what i belive is just about the perfect setup for this ROM
My evo is lightning fast, in app performance is almost comparable to my xoom
And with heavy usage my battery lasts at least twenty hours
Kernel: savaged Zen 2.2.1 bfs
Setcpu info: Max clock to 1136, try 1152 if 1136 is stable for Max clock, min 245. Savaged Zen governor, screen off profile with interactivex governor and min bumped to 384mhz. Eliminates all screen on lag
Market app: chainfire 3d its a graphics driver that increases all animations, 3d effects efficiency and speed, and improves battery life IMO follow in app instructions and install the driver, make sure to nand backup first and to not have the phone connected to the charger or computer when installing
Market app: battery calibration wipes battery stats to build new ones that are correct for your ROM kernel setup
Advanced setting in settings menu: performance settings, VM heap size set to 48
Market app : SD booster set SD cache to 3000 makes all SD apps and media faster.
Market app : busy box install 1.18.4
After all this install any user apps you wish and run fix permissions in ROM manager or recovery
Its a lengthy setup, but there is much profit to be had. This setup is faster then I've ever seen an evo run and has the best battery life of any ROM kernel combo I've tested.

[Q] Progressively decreasing battery life w/ Franco

A few days ago I started running a nightly of Franco Kernel. My battery life immediately increased and I was able to run for about 18 hours and 2.5 hours of screen time. However, after each progressive day, the battery life has decreased steadily until today I was barely able to squeeze out 12. I've checked my battery stats and it doesn't show that any particular app is hogging all the battery or anything. CPUSpy also says that it's entering deep sleep as usual. Any ideas and has anyone encountered this issue? Franco 156 with Liquidcool 1.4
Thanks in advance.

That could be dependant on soooo many variables... How is your signal strength in the area you reside? What are your settings, governors, Any kernel wakelocks? What are your ROM settings. Are you in WIFI, 2G or more?
I don't think you'll get an easy answer on your question here. Just play with your settings and see what suits you best.
I myself am using Franco with the Rascream ROM and getting currently 4hrs of screen on time on stock 1750 battery.
My settings:
ROM: Rascream
Kernel: Franco r174
Powermode: Balanced
Governor: On demand
Min: 729 MHz
Max 1228 MHz
OMAP4 interface 1.4
No other performance or battery saving apps or tweaks....
Just test your settings and be aware of wakelocks (but you allready are since you have the batterystat log included).

That is simple. I get about 17hrs uncharge off which 3,5 to 4 screen on. That is sufficient for my use. With Lazy and power safe I feel that the performance suffers too much. With these settings everything is still smooth and snappy... as you can see I adjusted the min and max from my CPU above the standard that comes with balanced power mode for the same purpose.

Thanks guys. I moved some things around and I'm getting better life again. It seems like the problem lied in either an app called 1Weather or My Data Manager. Have any of you heard anything about those apps?

I've used 1weather for months and it has never negatively effected my battery.

I'll play around with it for a few days. I wouldn't have imagined that it would be 1weather, but due to the nature of My Data Manger constantly keeping track of something could have run the battery down. Funny how it never showed up anywhere. Though the battery drained significantly during standby. I uninstalled both and battery is fine now. I'll see what happens when i put them back.

[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.
