Hey guys & gals just wanted 2 share something with u. I recently decided 2 uninstall cetcpu from my phone & decided 2 go with cpu tuner instead.In doing so i've noticed my battery life improve significantly with some profile tweaking of course.If you've run the virtuous htc sence rom with the pershoot o.c kernal u know how disgusting the battery life can b.It literally sucks the juice out of your battery like "Debbie" from Debbie does Dallas sucks the juice out of...well u know. Anyway,i also noticed how little juice the system resources now use up. I included a screenshot of the battery status screen.Hope this helps anyone with battery issues especially if your running the rom & kernal mentioned above, it worked 4 maybe it can work 4 u. P.S I have the screen set to 20% brightness,gps,wifi,blutooth,autosync all disabled.Only reason i mention this is because even with all these things disabled along with a few other,b4 installing cpu tuner my battery would still drain like crazy. Thx.
That's some horrible grammar.

Useless post, This isn't grade school or school period. If your worried about grammar over the Interwebz then i dont think you should be posting on a forum site.
Liek ma grammarz?
Anyway, Your saying the cpu tuner helps the battery life? I'll give this a go but I don't use any of the sense roms. I'm all for better battery life although I do get 15h on pershoots kernel running cm 6.1 stable.

i have almost the exact same info on mine with setcpu oc to 1ghz on CM6.1 and i get atleast a full day of use with frequent music and texts. alot better then any other android phone.
I don't know how you guys are having such bad battery life. Currently at the moment I am at 22h 11m 51s since unplugged with 57% left. This is all with CM6.1 RC4 w/ wifi + wifi calling on all the time when I am home, autosync on for everything, auto brightness, and some use of gps. I listen to music on my phone for atleast 3+ hours walking to and from class + texting, browsing, facebook, twitter, fantasy league during class and the occasional call, pretty good usage. with setcpu on oc to 1ghz with some profiles set up.
what if im not running sense?
If it works with sense I would think it'd work with most everything else.

Is the phone not quick enough at 1Ghz? I keep mines on stock speeds, have setcpu installed but don't use, and have CyanogensMod on it. I get the whole days worth plus more of battery. I can't even kill it when I want to recalibrate it.
A whole day for me is about 16-20 hours for me without charging. This is MADNESS!

Not that the phone is not fast enough. It's placebo effect where people "feel" that it needs to be faster when they overclock it at crazy speed. The G2 has already proved itself a speed monster, none of the android phones out there can top it right now. As for the battery life, I honestly don't notice any considerable improvement.

So what settings exactly are you using on the cpu tuner? Just wanted to know so I can replicate it.
My settings.
@quierotacobell...Under "Current" i have governor set to:conservative,Max:1094Ghz,Min:768Mhz.
"Profiles":
Performancendemand-Max:1097Ghz,Min:768Mhz
Good:conservative-Max:1094Ghz,Min:768Mhz
Normal:conservative-Max:1094Ghz,Min:768Mhz

Screen off:conservative-Max:768Mhz,Min:768Mhz
Extreme Power save:conservative-Max:768Mhz,Min:768Mhz(services set to 2g)
Keep in mind i have wifi,blutooth, & sync disabled all across the board.Also i'm simply stating what worked for me it's no guarantee it's going to work for you.
Hmm how can you get better battery life with CPU Tuner because the lowest you can go to minimum is 768?
Will try that out Utorrent, thanks.
Seriously, my GF and I just got new phones and her EVO rocks my Epic. I don't get it, thought the EVO sucked juice compared to the Epic?
We both have juice defender, otherwise hers is stock with standard sense widgets. She checks facebook and texts all day, plays words with friends but that's it. I'm obsessing, rooted with setcpu conservative 100/1000, I have force uninstalled mediahub+drm services, do the airplane trick on reboot, brightness on auto, services off except wifi when browsing, etc.
My phone lasts maybe 12 hours, hers has gone 27 hours, lasts 18+ easy every day. I feel like if I even touch my phone I lose 10%. Snes games? Phone is done. I basically let it sit and it slowly dies, yet still ends up 90%+ display usage on the battery.

I only got 8hours Until I got me, an extended battery Now I have mine on full bright and 4g,wifi,bluetooth,gps on full time. And 4 apps that update every 10 minutes 3 to 4 hours talk time and about 100+ text, get on the internet etc and the battery last about 12 hours
The biggest battery drainage from my phone came from 3g I live in area where 3g fluctuates allot which caused the battery drain
Have you ever thought of getting an extended battery?
Or you dont like the extra bulkiness
Otherwise can't you take it back and switch out for an evo?
I like my Epic like my women, slim and naked ;-)
I'm all stock, odined back to 2.1 before updating. I would suspect 3g due to my near-roaming status at home except for juice defender.
I can't calibrate my battery without clockwork (stock recovery now), think that would make a significant difference?

Watch for SyndicateROM Frozen, paired with the Twilight Zone kernel, in the next 24 hours. ACS team lead rjmjr69 got 30 hours of heavy use on the stock battery at 1.2ghz, and 16 hours extreme use (4G, WiFi, 3G, lots of SMS, MMS, email, web browsing, voice calls).

That is a key (perhaps not the only) problem. Set your brightness to as low as you can stand it (8% is my number). Use as much black & red as possible (if an app has a night mode, use it.) Use an all black wallpaper. These actions will not cause any miracles but it will make a noticeable difference in battery life.
Worst case scenario (all white background at full brightness), the Epic screen consumes more than three times (yes, >3x) as much power as the EVO. Of course it looks marvelous doing it.
Hrm, thx mosttoys, ill try it. Though honestly most of the time it looks like it's around 0% anyways (which is honestly where I like it).
Sent from my SPH-D700 using XDA App
Little info for you guys. I'm sitting at 15% right now after 11 hours. I didn't touch my phone except for a 45min conference call and half hour workout using 4g+pandora. I realize this is likely average for Epic users. Except check out my GFs super Evo.
Light use, words with friends, texting, browsing (she is unemployed and I work from home so I can vouch that she has been on and off it), 59% afterf 12 hours...

Op so ur liking the evo more? Just curious because I am considering giving my epic back to sprint for an evo because this has to be one of the most unreliable phones I have owned.
Sent from my EB13 Samsung Epic
To be honest, the features that made me choose the epic over the evo have let me down. The keyboard misses and the screen sucks too much juice. My gf still hasn't plugged in her evo, its at 42% 15h20m.
But, I just installed the new syndicate rom and have high hopes. I don't want to jump the gun but my keyboard seems fixed and it's very quick. If all proves stable and I get comparable battery life (~15 hours would be fine) ill be more than happy with my epic. I would hate to lose this screen and am used to a hardware keyboard again. Just hate feeling like I need to plug it in every time I use it.
Oh and the call quality is the worst I have ever experienced but I don't know if it's the tinny speaker or sprint...maybe both (came from tmobile).
Sent from my SPH-D700 using XDA App
My epic was working good but today was the final breaking point for me. My phone is literally used in life a death situations (I am a paramedic if you couldn't guess by user name lol) and today I was on a call where I had to pull my battery 6 times to get it to dial out.
For me that is a deal breaker. I have learned to live with the keyboard by slowing down. I was debating on giving the rom you are using a try and seeing how that goes.
Sent from my EB13 Samsung Epic
This probably won't apply to you if it's saying the display is 90%, but two other battery drains that you didn't mention are "use wireless networks" for location and google talk, which auto signs in unless you change it in the talk app settings.
Sent from my SPH-D700 using XDA App
Why don't you try switching phones with her for a day or two and see if it's still the case. If you have horrible reception in an area, that can quickly drain the battery. There are so many variables that come into play and the second you two leave each other's sides, there is no way to compare the phones.
Thx for the suggestions. My location settings are off and I signed out of gtalk.
We have been right next to each other as she isn't working and I work from home. However, while she was bragging how much "better" her phone is she mentioned that she keeps gps and wireless on all day. This could have an impact considering the spotty service here, I just thought that juice defender would take care of it (should turn off 3g).
Btw, I had her not charge her phone. She is sitting at 16% 1d2h53m

Running some of the different ROM's will help out anyone looking for better battery. I recommend trying it out i was not very happy at first with the epic after all the hype then I gave in and started rooting and flashing and I love the phone now.
Not sure if this is in the right place for this info or not. But...I flashed myns synergy rom a couple of weeks ago and have been getting decent battery life. Today my battery life is blowing me away. Going on 11 1/2 hours since being unppugged with my normal usage. Not heavy use by any means but moderate at least. I have never seen this kind of battery life on any other rom I have flashed. Any other synergy users seeing good battery life?

Yes, from what I have read, you have to use the kernel that comes with the rom.
I am getting HORRIBLE battery life with the synergy rom....almost to where I cant use it. I LOVE the rom, but the battery life is frustrating!
Hopefully Netarchy will develop one that will work with this type of rom and we will be saved.

I tried that for a bit over the weekend...but there was something I did not like about it...cant remember now. I will have a go with it again to verify.
At the end of the day...we can develop superb ROMS that have flashy flashes, but if the battery/components cant take it, then we are still at a stand still.
my battery life is good most of the time, but it seems there are periods where it drops quickly. i think it drops when the market alerts me about updates to my apps. both times i've had quick drops, the market has been the top app draining the battery and has a notification of updates. i don't see an option to turn of notifications is this updated version.

No but the netarchy kernel I use works just fine with my King's Alliance GB. It's all in the UNIVERSAL kernel, I should say
I usually get 24 hours up time and 3 hours awake before I've got to pop in a charged battery. Normally change out at 20% to keep it from going dead on me when I need it most.
I dunno man, just gingerbread itself appears to have fubared my phone. I wiped sd, wiped phone, factory reset, odined stock EC05 and took the forced EI22 update. Even still, android system chews through battery at >90%. A small thermonuclear power plant could not give my phone enough juice.
This coming after I tried multiple combinations of roms, kernels, uninstalling apps, and freezing data sucking apps that caused high wake locks....
I have tried stock gingerBreadEI22, ACS 3.5 - 5.5, ERA RC1 & 2, and Random Rom, with nubernel, different samurai kernels, and just whatever the chef cooked up. All the same, excessively high "system" battery usage.
Anyone is / was having the same issues and able to iron it out?
That reading for system is the norm. I get 24 hours with like 80%

I agree with Alkah0liK, but with my experience so far, if I don't use the phone all day it doesn't really use the battery, but as soon as I start talking, listen to music, or web surf it because a pig. I actually want to go back to 2.2 and use frozen rom again from ACS again. Can't figure out how yet though

Ok thanks, I was wondering what others were seeing.
I must be doing something it does not like. I can go a couple minutes with the screen on (at lowest setting mind you) and watch the battery drop 2-3% or more, almost dead battery within 10 - 12 hours even in /out of airplane mode...
Is there something really wonky with CWM? Funny thing is this started happening right about the time i switched over to v5. I am in the process of reverting back to wiping everything, odin to EC05, and going v3.1.01 again.
The battery life is better with gingerbread, but its not going to make your phone run 2-3 days on one battery life. Sorry my friend, those days are long gone. It would be very hard to find any cell phone that can run for longer than 24 hours these days.
No I get that, but I was able to use my phone for more than a couple hours a day before gingerbread. B4 the leaks I was running Viper Rom EXT4 with genocide at 1200 ondemand and still getting through the day. If I cut it back to 1000 and went easy I was only charging overnight to bump it back up to full.
I was even using RandomKing's and ERA's leak based roms with EH06 & EH17 without any issue. For me it really has been either the EI22 / CWM5 / latest roms.
Hey alky, I was also in your position. I tried every rom you tried, with minimal pleasing. My advice, if you can live without 4g, flash the current cyanogen and set the render effect on night mode. Enjoy a thorough battery life my friend. Nothing beats it thus far. Can't wait till we see cm9.

Thanks! That was actually going to be my next try. I only get 4G when I am downtown, not very much as of late anyway.
FYI- I have found what I suspect as two possible culprits on ACS 5.1 & 5.5, and ERA RC1 & 2. According to better battery stats CM_VnoteService and *Sync for GTalk will run and run and run unless you open the applications and go through initial setup. Those two process will stay stopped so long as I leave them open / connected, once I close them - the partial wakelocks restart and run until you open the apps again (or just uninstall).
Even with my obsessively high amount of .acore launcher time and better batter stats application usage, they are still well below the "system" usage under the process dropdown.
It definately sips battery when not in use. Although I feel I get more screen on time with ACS ICS. I regularly have over 3 hours of screen on time with GB, I don't remember getting 3 hours on even SRF 1.2.

Turn off your syncs. If there is no signal your syncs will keep trying and burn up your battery. Turning off data mode in low to no signal areas will conserve battery.

Make sure upgrading to GB did not change any syncs. Also make sure new apps aren't loading into memory and sucking battery like Talk or Google +. Grab Memory Booster lite and pull up the task killer to see everything loading on your phone. The stock task killer sucks.
I recommend paying the $50 for battery and portable charger/storage unit. I'm a stock user who just had 41 hours with my new battery with 2hrs of screen time. I really like having two batteries too. No more charging cords connected to the phone...ever
Edit: the batt. I bought was a stock 1500mah batt. and charger kit from a sprint store. No regrets

Still running 100% ERA Legendary v4.0.1 (with provided kernel) and I squeezed ~74 hours of pure standby time out of my stock battery.
Data Sync (FB every 6hrs, Weather every 2hrs, Google push)/GPS/Auto Brightness = on
TWS = 4%
Display Time = ~24mins (sent 3 texts and checked 1 voicemail)
100% on 3G
Had I turned off all synching, GPS and lowered brightness all the way, I would have probably gotten 4 days.
Battery life has heavily depended on the strength of signal for me as well. I moved recently and have been living in the basement while the renovations are going on upstairs. No airave (it is used at a different location) means little to no signal in a brick house due to Sprint's POS signal frequency. Although I've been flashing different kernels and maybe not allowing them to settle + undervoling a bit (very conservatively, will not OC over 1100). But it is true that since days I was on BB Tour, not one phone lasted a full day without an extended battery. I'm pretty much decided on VZW switch once Prime comes out - one of the factors is better expected power management of ICS and possibility of adding an extended battery without worrying about making the phone too bulky (given how thin it is).
Man that sucks, I've always had great battery with gingerbread. Right now I'm on RC2

Alright, nobody probably remembers me, but thats okay! Lol
Anyway, my flashing addiction has unfortunately been starving due to being way too busy with work and such. BUT I FINALLY HAVE FREE TIME! Haha,
So I'm still on Froyo, Syndicate's Frozen ROM (Yeah I know I'm two android versions behind). So I was wondering, whats the steps to going to CM9?
My current setup is:
Syndicate frozen ROM
CWM3
Genocide Kernel
EH17 Modem
Don't get me wrong, I'm not new to any of this, I'm just wondering what the exact steps are if theres anything fancy that needs to be done coming from such an old setup? Or is it as simple as:
Odin stock DK28
Root
Odin CWM(What number are we on now? Link please?)
Flash CM9
Flash Gapps?
Thanks guys!
Flash cwm5 boot into clockword mode wipe "once"
Data cache and dalvik
Flash cm9 it will reboot and install the update then boots up during the animation pull the battery go back in and flash the gapps viola cm9

So theres no need to flash to stock / reroot / all that jazz I did when going from eclair to froyo? Haha.
Not unless you wanna update the modem. You could flash the new EL30.tar with odin, flash cwm5, then flash cm9 in cwm5.

Sounds easy enough, Is EL30 modem a big improvement over EH17?
Also hows the every-day-usage capability of CM9?

Not bad at all for an Alpha only a few weeks old for us. Minor bugs that not everyone experiences. A lot of us are using it as a daily. Battery life is not good because it uses a lot of resources. It was meant to run on phones with twice the RAM.

Cm9 runs good. Battery life was a deal breaker for me and it was a bit sluggish. I just barely came from srf 1.2 ef02 genocide 2.0 myself (which was rock solid and superfast).
I settled on gleangb for now.

Battery life is decent enough for my tastes. The only bugs I'm experiencing now is some tearing in video playback and some minor artifacts in video recording (sometimes). Other than that it's pretty rock solid imo.

Battery life for me is very good on ics. But its not my primary running OS due to its bugs.

Please stop talking about things that you don't understand. Battery life has little to do with the RAM usage. CM9 alpha4 for me is easily goes 28 hours battery life with a 1.5 year old original 1500mah Epic battery. The trick is to prevent wakelocks, I'm usually ~90% in deep sleep. I disable LED notifications, all haptic feedback, notifications for anything that uses push data (Facebook, gmail, email, etc.) I get an extra ~8 hours battery life if I use Juice Defender to turn off 3G data and Wifi when the screen is off. It takes a little delay for data to start again, but that is acceptable to me. If all my push data notifications are turned off anyway, why bother having data enabled at all?
If someone really needs to contact me they can SMS or Call, which causes both vibrate and sound. Otherwise I'll see messages when I too often turn on the phone screen.

Pretty much my exact same setup, I got tired of using Juice Defender because of the lag to start data back up but when I was using it I was getting around 33 hours. I don't use my phone much except for calls and sms so this works fine for me.
Also, I remember you SemiGamer!

I really respect you and all that you do for us but with all due respect, using your phone for more than just a phone on CM9 eats up the battery pretty quickly. Browsing XDA, polling 4 business email accounts, or on the web uses about 50% more battery than it did on CM7. It was mentioned at initial release how it was meant to run on phones with twice the RAM which attributes to it's sluggishness and lower battery life. I know each Alpha just gets better and better and that is awesome but it will be a while if at all that it can compete with something like CM7 for battery life. I am sure with the same setup you have you can get 50% more battery life on CM7.

Agreed I pulled 5 hours of display on cm7 and can't hardly pull 2h 45m on cm9 same setup no wakelocks no sync browsing xda undervolting as far as my phone will handle..nothing helps. Had to get a 3500mah to compensate the gigantic battery usage and am lucky to 5h45m on it over 13hrs uptime. However we all use our phones differently and to you @wtogami you may see no difference, however for others it drops like a rock.
Anyways semigamer how'd it go?

Yeah if you just stare at your phone while the screen is off and dont do anything haha. But even still with my stock battery haha not even 6 to 7 hours it would be dead. with a 3500 it last longer but its not worth it right now.
Once CM9 progresses to CM7 state then it might be worth it. Still ICS requires more ram so yeah your battery is going to die faster because of memory swapping. IDC what anyone says ICS on our phones still would not last as long as GB.
Plus there was no reason to be rude about. I may not be a DEV but I know how Android works with resource swapping and memory clearing.

Exactly i don't understand why everyone starts retaliate and then the only way to reply is retaliating back, if not then they pass on by. Its so frustrating
Hi, I noticed ics charges faster.
I absolutely love when people who don't build the ****, don't know how to, and couldn't possibly in fine detail explain how it functions argue with the people who do. Cause they like, know better. I'd say if one of the EpicCmTeam says the RAM shortage isn't the cause of the excessive battery drain, he's probably right, as he works directly with providing us with the build, on a level none of us understand or have skill in. Kinda like how certain people wanna argue that they know better than a google engineer. That clearing batterystats does in fact change your battery life despite very explicit explanation from said engineer dictating how that file holds nothing more than the statistics displayed to you about your battery under settings.

Welp I'll stay out of you guy's debate for now.. Lol.
Thank to everyone that helped me with my OP, Got eveything up and running real easily.
One question left, does Voicemail work with CM9? Not getting any voicemails even though I'm told some ppl left me some. Any way to get Visual Voicemail to work?
(Know someone prolly asked / found a fix already, sorry for taking the lazy way out)
