I dont know what it is, I have a task killer that kills running apps but it doesnt seem to work.
In 20 mins my battery drops 10% and i dont do much so i dont know what cases it.
Does anyone know a forum that I can get info from? OR any kernel that can help me with battery life?
If your going to be rude please dont comment because I WILL return the animosity!!! THANK YOU!
Task killers cause more problems then they solve, don't use them.

Well what can I use bc nothing seems to be working at this point.
What's your battery usage showing as the process that drains the most battery.
It's probably background sync from e-mail or IM clients.

Many are using the dopio kernel found in the dev section and setting the main to conservative, then creating one profile that sets the cpu at 245/245 when the screen is off. I have also seen/used a free app "juicedefender" that in theory looks helpful. Unfortunately, I suffer from obsessive ROM updating disorder and cant speak to how effective these methods are as my constant reflashing and rebooting destroy battery life.

Honestly, i didnt check.
I was told it may have been trhe rom , so i flashed a new one.
Now im going to monitor it and see if i have any changes.

Aha!
I suffer from the same problem!
I installed the app and im going to see if it helps.
Thanks!
Did you wipe battery stats and charge properly?
I use Advanced Task Killer Pro and have it kill apps on screen off.
Along with SetCPU to clock 245/245 on screen off.
A day, little use, I go down 8%. Regular use, about 20%.
My max is about 4 days. Using CM6 with dumfuq's 844 kernel.

What rom are using? My wifes phone is running cm6.0.0 and when I checked this morning was over 2 1/2 days uptime and 42% battery left.
Running stable CM 6.1 with cm kernel & followed the steps of calibrating battery & my battery lifes still horrible, currently 1 hour after calibration and already down 2 70% from being on internet & a few texts

have u got spare parts? open it up and look at battery history and the running vs screen on time.
they should be the same but i can almost guarantee that your phone is still running whilst the screen is off. you need to find out the app which is keeping a wakelock on ur device and delete/change its settings
Ok thanx..will try this

Sorry for the noobish question, but can I compare the two. I went to spare parts and could not see where to compare screen on time vs running.
I recently tried to calibrate y battery, but sinse my screen does not shut off on its own as before. I've aleady checked the screen timers and all is as it was before.
Right now I am @ 4.5 hrs since I unplugged and I am sitting @ 76%, with little use...kinda sucks!!!!

What kinds of widgets do you have running in the background and how often are they pulling data?
Also, how many days have you been on CM 6.1? I upgraded from RC3 and my battery life is much improved. The first two days it was eating a lot as it 'calibrated' itself but now I can easily make it through a full days use with about 40% to spare.
I adjusted my background widgets and how often they pulled data and this really helped my battery life. Also, a poor signal can have VERY ADVERSE affects on battery life. For example, I work in a prison where cell phone reception is awful. If I am at work for 3 hours and leave the phone in 3G mode, I can easily go through 30% battery while the phone tries to find a signal...
Any idea how long will it take the batt tocalibrate???? I did the recalibration process on thurday night, and my battery sucks now.
I'm sitting on 49% only 4 hours unplugged. Before I was getting somewhere around 55-60% at this time interval...
Any ideas?

Alright boys try this. I got over 2 days worth of lifetime with this set up.
-Download SetCPU
Set your profile to 245/245 screen off with priority at 100%.
-Turn brightness to 0%
-Turn GPS off (Go to Settings->Location and Security-> turn off all that GPS crap
-Leave 3G off until you actually need it, then turn it back off after you're done with it
-Leave bluetooth off
-Don't have garbage widgets lying all over the place on 7 homescreens. I only have like 5 widgets spread out on 2 homescreens.
Are you guys running CM 6.1? Cause I am.
Did you guys overclock?
Thank me if it worked out for you =P

Convolution Thanks for the reply, but im more interested in getting a few more hours but with certain level of freedom. I am not all that interested in switching things on and off every time I need them, but I understand what you mean.
I'm looking to get 16 hours of moderate use...that should be plenty. I currently turn off wi-fi and gps since I seldom use gs, and wifi is governed by a profile manager, and it's on only at night.
but setting connection down to 2G, and killing all screen brightness renders the device (IMHO) useless. Also, SetCPU @245 100%, would really hinder the device.
I am running CM6.1 Stable and I am running OC'd @ 1497, but on "On Demand" profile, so to use only as needed.
I still have to try Pershoot's kernel, I think I will flash it tonight to see what happens.
I am also experiencing some oddity with my screen time-out feature...it's not working.....my screen refuses to turn off by itself, I have to lock the device physically for it to take effect....not sure what changed...but the regular parameters are set properly.
I'm getting 2-3 days with the stock WWE ROM that came with the phone. Brightness is set to Auto, but I keep GPS, BT, WiFi and mobile data connection off until I need them. Other than that, I talk about 20-40 mins/day, send out a few texts, listen to the radio, read my feeds and e-mail - pretty much everything the phone was made for.
IMHO, the "calibration" is bullcrap, it's just an impression that it lasts longer afterwards.

Basically the same setup I have in terms of connectivity except for data.....does it really have that much impact on battery life?
What would I missing if I decide to turn data off?
Thanks!
Huge impact. Try it out for a day or two. Or just install Juice Defender, which disables it while the screen is off, turning it on at set intervals (like for 1 min every half hour) to let it sync.
Thanks Keinengel....I'll look up Juice Defender...sounds like the right thing!
i get atleast a day and a half out of my phone and i had it for about a week now. best battery ive had for a while now.
Wow guys...installed juice defender and pershoot's kernel, and only gone 1% in about 2.5 hour....I'll report again tomorrow

Back when I was on fresh I used to get 2.20x with the aggressive profile.
Battery almost lasted 24 hours with very light use.
With Myn's, it last 17-19 hours and I am willing to sacrifice the extra hours for the performance.
Are you using the Ultimate juice or just plain juice? I want to upgrade to Myns 5 but I don't want new radios.

Yes I am using ultimate juice. If I remember correctly, you have to upgrade all your radios when you switch to a 3.70 rom.
I need to get ultimate but I don't pay the bill so I have to work around it. I wish I could just use paypal to buy it -_-'

I was trying JuiceDefender, but didn't really see what it was doing over Tasker and CPU Tuner and/or smartass. It seems to me that with Tasker doing WiFi and CPU Tuner to either do CPU profiles or just setting to smartass that there wasn't much that JuiceDefender added.

You can do almost everything juicedefender does with tasker and cpu tuner if set up right. Tasker is a little harder to use (though does have a lot more capability). Basically juicedefender is an alternative to doing tasker and cpu tuner not something you need in addition to. Basically with ultimate you can manage screen off cpu speeds, turn mobile data, wifi,4g on and off by screen schedule and or an app being active.
Personally i use juicedefener (ultimate) i get around 1.8x on CM 6.1.2 and about 2 on fresh. it will all depend on your settings and how often your screen is off. I go several hours at a time where my screen is off then ussually use it for 30- an hour between breaks and has greatly increased life because of this i say ..... YAY
Before I rooted my EVO, I was using JD Ultimate and the most life I got outta my phone was 1.90x but that when I didnt use my 4G and Wifi. When I would keep those enabled I would get about 1.25x
Now that I m rooted, I get about 2.30x avg. - Again though - I don't keep my radios on all the time, I only use my Wifi when Im home and I hardly ever use 4G. I live in houston and the signal here is good when you are in the city - but where I live - I sit right on the edge of good and bad signal and it makes my phone VERY laggy and choppy b/c its constantly connecting/disconnecting from the 4G network.
I would go ahead and upgrade to Ultimate cause its worth it...
can't live without juicedefender, period. Android is crippled without it -- Google should seriously consider integrating this fucntionality into the standard OS.
Without JD, my phone is completely DEAD by lunchtime every day (~5-6 hours after unplugging in the morning). Everything is set to sync automatically, of course, so it's there whenever I pick up the phone. With JD, I still have battery at night before I go to sleep. In fact even if I forget to plug the phone in at night, I still have some (very little) juice in the morning. When the battery gets below a certain percent, it goes into super-duper conservative mode and will NOT let the battery die. My counter only reads 2.15x but I'm sure it is actually much much more than that.
I use the most up-to-date beta version with ultimatejuice, but I don't really use all the features of the paid version (I still manually toggle wifi when I am at home because that is the only place I use it.) Just remember every time you update JD you need to open up the app and re-enable it so it starts working again..

I say No Juice. Running with the stock HTC kernel, I can go 24hours with moderate usage.
To me moderate use is:
1 hour of talk
50-100 texts
2 hours of gaming (bubble blast, gun bro's, bubble blast, ect...)
30 minutes of web on 3g
30 minutes of web on 4g
On the fence
I found that juice defender did help improve my battery life a little bit. But I'm still kinda on the fence about it. At times it messes with your data connections (3g, 4g, wifi) and things like gmail and calendars are not able to sync. Not too big a deal but I'm just not sure I like it yet.
So is that a yay or a nay? Also for 1.08* is it worth it?

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.

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.

I use my mostly as a media device, but since I'm always near a wifi connection either at home, on campus or whatever, I also use Google Voice and Talkatone for free calls and texts and it works great. I also got two brand new Anker batteries and an external charger and they work fine (my old stock battery swelled and was just overall dead). So I'll use my phone in Airplane mode with Wifi on and I get around 22 hours with 90 minutes screen on time, which is decent, but I feel like it should be better than that. Depending on the ROM, I have gotten as much as 40 hours battery life (which is great) and as little as 14 hours, and this is ALL on Airplane mode with Wifi toggling, so I'm guessing its software/settings related.
i am on a new ROM as of yesterday so I want to make sure I have my settings the best from the jump. I turned off all Location services, screen brightness is low and with the exception of push gmail and google voice notifications, the shortest polling interval time I have for any app is 4 hours. Any other settings I can change to maximize battery life?
One thing you can try using gsam battery monitor to see of anything keeps the phone awake when the screen is off.
You can hibernate apps with greenify and can use dsbatterysaver to kill data on screen off.
Edit: you can also use Romtoolbox to lower max CPU speed to 800/1000mhz and set governor to powersave/conservative depending on the kernel you're running.
Tegrak can help undervolt but the app is a paid app. Romtoolbox has a free version.

To OP:
tt281gt has some great suggestions... I had an issue with conservative governor causing my flacs to skip. I was also running at 1000mhz. I changed to pegasusq and it was good to go. At one point I was using one of Kobridge's tweaks.I think it was Placebo2.0 It was the one where you had to pick like shift1,2,3 or 4 . Shift 3 had some great mods for the conservative gov. It was still great on battery but lost any laggyness. I know he has newer products that might be better than that. Maybe you can hit him up directly with your scenario and he can point you in the right direction. What your asking for is right up his alley!
