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.

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.

Hey, I'm trying to fix my battery drain during light use. Having screen on for not even 5 minutes eats around 2% of my battery. I've calibrated, gone through many different ROMs [GB(CM7,MIUI,Sense) and ICS] with full wipes(format and wipe). leading to my question in hand... how do I completely wipe my phone? I visit the wifi settings and see a wifi history that were from a pretty long time ago(before wipes). This leaves me thinking I have not fully wiped my phone in between flashing. Does the google account save wifi history or something? Thanks for any tips!
My problem still persists any help is appreciated

You seem to be wiping your phone correctly. The WiFi settings are backed up under the Google account and are restored when you add the account again. It also backs up other settings, wallpaper, and app data of certain apps. Here's an easy way to fully wipe your phone (including the SD card app files in .android_secure) - http://tinyurl.com/66fc8og
It's called super wipe script and it is from the Android Revolution HD ROM thread, thanks to mike1986.
Sometimes the battery loses it's ability to hold charge after sometime. This happens when the battery is quite old or due to various reasons that I don't know. You'll need to get a new battery then.
On the ROM side, a good ROM+kernel combo gives the best battery life. Instead of using a plethora of apps to save battery, finding the right ROM & kernel combo and choosing a good CPU governor and min-max frequency settings will give you much less battery drain. I don't use any battery saving apps, but I run a great ROM (CM7.2 RC1) with an awesome kernel (LorDModUE 8.9b7), with smartassv2 governor running 122-1152 Mhz and a few build.prop tweaks.
You can try out my combo and see if you're getting any better battery life. The max I've gotten recently is 14 hours of heavy use with 4 hours of screen on time, wifi on for 75% of the time and a lot of web browsing and video watching. I usually keep my phone in 2G mode and only change to 3G when I need to use the internet. 3G drains the battery really fast. On average I get around 13 hours heavy use, 1 day medium use and more than a day of light use (with mobile data off unless when necessary). I get around 1% per hour drain in standby.
You can try this ROM VictoryMod by victoryo. It has my same ROM+kernel combo I've mentioned before + build.prop tweaks. Change the CPU governor to smartassv2 with 122-1152 Mhz frequency. It gives great battery life.
Among the Sense ROMs, Android Revolution HD with klquicksall's kernel and LeeDrOiD HD with LeeDrOiD's kernel give awesome battery life.
Thanks for the reply! I greatly appreciate it. As for my ROM, I've been using the latest LeeDroid, but the battery drain seems to be happening across all the ROMs I've tried recently. I never install battery saving apps, and I keep default kernels and settings. The problem is probably with my battery, I've had this phone since last May, so almost a year. I'll see if I can get this problem sorted out. Thanks again!
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).

Could you explain why do you use those?
Why not power save mode or lazy governor?

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.
Hi everyone as you can tell I'm a noob, so please just take it easy on me thanks! So here is the problem I have so recently I installed DARTHSTALKER V8 on my Galaxy S3 T999 and my battery life was like 4 hours so I was confused because people were getting like 16 hours. So what I did was I downloaded a new kernel called "LJA TWiz-JB-OC" v1.1c. So it increased my battery life to 5 hours on like a 50% battery. So I was wondering like what settings can I use on this kernel or what other kernel could get me this kind of battery life of 16 hours or more. Also, I found that someone said, " this kernel works flawlessly on darthstaker v8. 1350-192, ondemand, sio! UV -75" but I don't know how to set this kind of stuff.
Please Help Thanks!
Download set cpu, from there you can adjust, frequency clocks, governor, scheduler, undervolt, turn all animation or window transitions to 0.5x in developer options, turn off battery saver, email, facebook etc make them sync every hour or two, reduce brightness to 40-50%. Auto dim screen or auto lock after 30secs or 1 minute.
When I'm at work my wi-fi is turned on all the time as there is no signal in the basement i get 12-14 hours on my battery.

Hi everyone,
from 1 month ago i notice very low battery life, my phone is 0% at the afternoon, i always use AK series with Paranoid ( switch sometimes to AOKP,CM and Stock ), Full disk encryption, this is normal, somebody had this problem from 4.2.2, but the strange thing is, this battery drain is high only when using custom kernel ( tried franco, Ak, and Lean), with other kernel i don't have this problem, yesterday i tried with full rom reflash without any custom kernel my battery life. i come back to home at 22:00 ( 10:00PM ) with 20% , same usage like always.
Use always 3G data on, with 50% time on wireless, all sync on , google now off, Apps timeout sync set to 1 hour
I investigate about this thing, i notice for first thing this: custom kernel is too aggressive, new interactive designed for 3.4 series is too aggressive, switch to MAX without any need ( 10-20% load ), but i don't know why battery life is so low anyway...
Franco kernel is more horrible for me, battery went down like 1%/4min ( with some sms and whatsapp )
lean seems more neutral here, but always high battery drain
Here the are some stats from this day testing ( from 100% to 0% ) (*All kernel using stock kernel configuration )
1) Stock kernel
16.44 Hours on battery
02.57 Hours on screen on
2) Ak Kernel
14.08 Hours on battery
01.44 Hours on screen on
3) Franco kernel
07.49 Hours on battery
02.03 Hours on screen on
4) Lean Kernel
18.31 Hours on battery
2.11 Hours on screen on
Anyone else has noticed this strange issue? on custom kernel i always noticed overheating too, this is very strange!
Try ondemandplus, I've had no problems with that.
Unless you just have to have facebook provide notifications on stuff disable the facebook notifications. I did that on my GNex and saw an increase of several hours to my battery life with more screen on time. I've also noticed for some reason that texting seems to drain my battery really quickly and can't seem to find a reason for this.
I know this, disabled notification stuff from day1, but the strange thing is stock kernel has no problem ,46 % with 2 hours battery on stock

Here is mine today. I'm running stock with Franco Kernel. Everything is syncing except for facebook. I also have about 1:30 hr's of phone calls today.
