Best 2.2 battery life rom (question) - Epic 4G General

Currently I am using viper and I like it...kinda, I'm not liking the battery life and some of the apps included are uselesto me such as feeds. I havnt played with the others, so I am looking to gather info on each for pros/cons concerning battery life, apps, preformance.
The rom threads are confusing to see the latest version...look at vipers and see. I used to use epic experience and loved the way punk had it laid out when new updates came out.

Since they all use the same kernel I doubt you are going to see much difference between them. Changing your habits/running applications should have a much greater impact.
People talk about this phone like it has such bad battery life... I had a Touch Pro that literally came with two batteries because it was so bad. This phone has always, ALWAYS has lasted me the entire waking day.

Like I said viper has a bunch of usless things to me, and if there was less "junk" it would save battery?

Without the source available there isn't a whole lot the devs can do other than theme it up, add some apps, and do some minor tweaking. As of right now the differences you'll see in battery life will be primarily due to usage. So If you don't like a whole lot of extras on yours I would suggest going with a vanilla build and just removing the sprint bloatware...

you can use sdx app remover to remove useless .apks and .odexs. if you're worried about battery life, kill the drm services. other than that, useless apps that you don't use shouldn't drain battery life.

foyo? or stay on 2.1? is it worth it?

I have been dabating wether or not to flash a froyo rom and modem. I am currently using ee with phoenix kernel and loving the battery life i get out of it. I have searched the threads but not to much pertaining the the battery life of froyo as there is no kernels yet, most replies to battery life on froyo are a simple its good or i get good battery life. I Wa wondering what kind of battery life people are getting with froyo roms. battery life is the 1st on my list of importance so some with respectable performance would be nice to know so i could make my first froyo jump. Thanks in advance.
I've been on it for a few days now (DK17). I don't use any task manager, or juice defender or anything like that. I have a start-up manager (autoruns) and thats it. I unplugged my phone yesterday at 10:30am and 12 hours later I still had 40-45% remaining after some moderate use... angry birds, asphalt and web browsing mainly.
Hope that helps!
I just flashed 2.2 and used it all day at work for texting, calling, facebook and web browsing and after 9 hours at work i had just under 80% battery life left.
If you are after battery life, then stay on 2.1. I have 4 backup batteries and didn't mind going to 2.2, but I did have a considerable battery life decrease. I find myself changing batteries atleast once a day with these beta 2.2 releases. Recently I haven't noticed it as much, but I think that is due to my getting used to the routine of changing batts every 6-8 hours depending on use.
I really do enjoy the perks of 2.2 though. Flash player with Hulu is awesome, faster phone than 2.1, and the developers are doing a great job of getting some custom themes integrated right now, which makes it not only run great, but look awesome.

I've used it the second it came out, some noticeable snags you'll work around just fine. I've had it for atleast 3ish weeks no major setbacks I guess. Just used clock and flashed it. Happy with over all with flash and other new twists....phone can be hairy at times, but I've foun several androids do on 2.2. Speaker everytme you pick up a call with he feature "off". I have had the epic on the first day at day break.....

What roms are being used for the better battery life? And how much faster then 2.1 over clocked to 1.2ghz is it if any?

I'd stay with 2.1 for now. My phone took a serious performance hit going to 2.2... something is wrong with that kernel. Not optimized yet maybe?

I don't know about you guys, but I am using ACS's Froyo build and my Epic has never had better battery life. By a large margin.
It seems the latest froyo release has been outstanding in terms of battery life. If you're looking for battery efficiency, definitely go with a froyo rom. If you're looking for performance, go with eclair. All in all however, froyo roms are fairly snappy especially considering they are at stock speeds. Can't wait for battery life increases once froyo roms get UV'd.
EDIT: on second thought, I'd have to recommend froyo either way. The improved web browser performance + flash as well as froyo gapps alone make the jump worth it. There's really no 'lag' to speak of on froyo roms... merely, the phone just seems faster on eclair switching between apps and loading/closing them.
I'm using epic experience 2.0(froyo) and my epic has never performed better. Especially gps locks in like 2-3 seconds even without wireless location check marked. Very fast and smooth. Probably just as fast if not faster than 2.1 overclocked to 1.2. For me it seems anyway. Way worth it in my opinion.

Honest to God I'll never understand comments such as these. If battery life is the most important thing then why the hell did you buy the most power hungry phone? You bought it for performance didn't you???? Performance and battery life are polar opposites. Much like horsepower and fuel economy.
Let me save you some suspense... you'll never get more than a day out of this phone. At least not if you actually use the damn thing. If you travel, take a car charger. If you are in the office, have a charger with you. If your job requires you to be away from power then bring an external battery. The phone lasts a normal work day between charges so install 2.2 and enjoy your phone for what it is... a powerhouse!
Btw, the battery life seems pretty good in comparison to stock 2.1.
Or u can buy one of the double or more life batteries for $100 that comes with a modified battery cover to fit the extended battery, then couple it with a kickass kernel (phoenix) and have the best of both worlds

I lost GPS going to Froyo which worked perfectly for me in 2.1. Other than that everything else is better..
I found wifi on froyo drains battery like crazy. Also when I set the browser bookmark to list view the next time I open bookmark brower will fc on me. Other then these and the camera bug, phone seemed to work well..

Better battery life?

Is there anyway to increase the battery life on the aria? I love it, and I love sense, but within about twelve or so hours of moderate use in the day my battery is left with roughly 20%. With cyanogenmod, the same period of time and usage, I was left at 60% battery. I know the sense launcher and Widgets play a little part of that, but even with my hero, battery life wasn't that much of a difference between vanilla and sense roms.
Sent from my Liberty using XDA App
I would suggest an App killer. I have yet to try cyanogen's ROM but am on Attn1's Liberated Rom. I have Bluetooth enabled all day and by the end of 12hrs it is at 25% or so. Not saying switch. I would try Advanced task killer. Have many friends using that on their EVO's and Nexuses and their battery is wayyyy better.

I've tried all the tricks. I always have advanced task killer no matter what rom I'm running. I change thee location settings, network settings, screen brightness etc. I love htc sense but I don't want the battery life that comes with it. I know what my tricks are,i just want to see what the community had come up with.

I have read somewhere on the google (official google page about android stuff), using task killers does NOT improve battery life because background apps stated as "suspended" when they are in background. I dont know if I get it right. I will post link if I can find.
P.S. Couldn't find it but it was something similar with this:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Of course, you must take control off applications really "running" in background and preventing the phone sleep state. Not just "killing" all applications.

Mmmmm. If there's one thing that could drag me over from the standard Liberated ROM over to the Froyo ROM, it would be longer battery life.*
Perhaps I'll give it a shot this weekend.

* I've resisted the urge to switch, only because I've heard wildly conflicting stories about how fast it runs on the Aria.
don't use task killer it will kill the app but the app will just start up again in the background cause the battery to run out. it says its in the background and that's true but its not running its idle and isn't affecting battery.

I have to say, at stock clock it got sluggish at times, overclocked to 800 though its running absolutely great!

You might want to try out an app called Autostarts. Just make sure you don't turn anything off you really are gonna need. Try this with advanced task killer and the apps wont load back up.

Check that you do not have an app constantly running in the background - on my stetup, I found that the XDA app was burning 3-5% CPU time spooling in the background doing nothing. (using OSMonitor)
For what its worth, I went back to the Sense ROM (FR008) from CM6.1 because of strange battery behavior - some days dropping to 30-40% after a full day, others it would be dead by 5pm. I dont consider my self a heavy user either. I do not see a significant difference in battery life between the two ROMs, if you throw out the aberrant days that CM would go nuts on me.

[Q] Choosing a ROM, battery life a must

Hi. I'm thinking about flashing my first ROM on the Droid X. I've been using rooted GB for awhile and I'm finally just getting bored and ready to try something different. I really am not looking for much though. My order of prefs are:
Stability > Battery Life > Performance
Mods and tweaks and things of that nature are not really a huge concern for me. I just want everything to work well, and have great battery life. I'd love to hear some suggestions.

i know this is gonna sound funny maybe.
i have a vzw droid-x that i am running the alltel rom on.
i put the phone in airplane mode and enable:
wifi off never
power savings wifi always on
i get at least 24hrs
now the equivalent rom to this would be the vzw 2.2.340
if you do not enable airplane mode and disable everything else i dont see why you would not be able to get the same results.
i get amazing battery life with the rom i said i was using above and dont forget this is with an "always on wifi" never ever disconnects
DSX and Shuji are great candidates for you. DSX is not flashy. It is completely reliable and battery life is stellar. You will not be disappointed. Shuji has great battery life as well and is more customizable. My primary phone always stays on DSX though. Ran 5 straight hours of Netflix and still had 5% left. Not sure too many roms can do that.

I also run DarkSlideX and can verify what is said above. Battery life is excellent. I probably make 20-30 minutes of call a day along with 2-3 dozen texts and 2-4 hours of web, forums, etc. I'm usually off the charger around 6:30am and back on it around 9-10pm with 20-30% battery remaining.
Stability has been awesome as well. I have had one reboot in 2 months, it happened about an hour after flash and that was it. BBCrackman did an excellent job with this.
If you want to try a theme for it, wulf has made some equally as nice themes, too. There are also a few custom sliders and a crt mod, too.
Everything can be found at MyDroidWorld and each has a dedicated thread complete with instructions. Best part is you're already on the pre-rooted 596, so all you should have to do is flash DSX right on top.
EDIT: also, much of the VZW bloat has been removed and it still has some blur present. HDMI support is working, too.

Give apex a try. Very stable and fast. I usually got about 18+ hours on stock battery with heavy usage.
Sent from my SCH-I510 using XDA Premium App
I'm not quite sure how to respond to Apex and 18 hours of HEAVY usage. On a stock battery? Up till now I've never questioned someone's post, but this individual seems to have a serious question he'd like some input on. I don't have to be a modder, developer or themer to know no rom gives 18 hours of heavy use unless it's hooked up to a car battery. And even that may be questionable.

What about vanilla rom?
Thanks for the feedback guys. DSX and Shuji were a couple that had jumped out at me in my readings. I think I'll give them a shot!

Dsx was my first flash and haven't gone looking for another. Stable good battery, I'm a heavy user and smooth.

ROM with best battery life?

It all started back in May. I purchased my first "smart" phone, and caught a qbking77 video on how to root. Now I'm addicted to crack, and love our awesome devs. They have done so much for me, if they had car trouble, id be the first to lend my hand. On to my question now. I realize our hardware doesn't respond the same to various roms, but why is it, even after multiple epic 4g's, does MIUI always have the best battery life? I know its not fully complete, but it just rapes the competition. Any knowledge here?
Sent from my SPH-D700 using XDA App
probably because as you said, its not completely running everything the hardware can so it uses less battery
From my understanding though, mms and 4g still aren't working, which I never use anyway, and these are huge bettery drainers for a lot of ROMs, so what gives? 4g is sprints joke laughing down on us. MIUI is an asian based software right? Is it the 2.3.7 tweaks that make it better?

I also expected better battery life with GB, but it did not happen. Downloaded betterbatterystats and identified a partial wakelock, froze that app... testing it out again.

i guess each device is different. before i went to gb, i used to take my phone to the gym with me as for music. i usually streamed pandora, sirius, or googlemusic, sometimes listening from my phones hd. I would go to the gym about 1.5-2 hrs and leave with about using 25-35% of battery avg. With GB, i used about~20%... but this is only 2 days so far..
Well, I've been flashing and testing a hell of a lot of Rom and kernels lately, and the best battery life seems to be with SenseiSimple's SleeperROM. I use the latest version of earthbound [iap]'s Samurai kernel. That kernel allows for a hell of a lot of flexibility in terms of frequency and voltage, so you can fiddle around a bit to find a combo that works for you best. The SleeperROM already uses the Samurai kernel by default, but it is presently still compatible with the latest BETA version.

ROM and battery life question

Hi, I have a family member with a epic 4g, and they've complained about battery life quite a bit today. I checked the battery stats and noticed it was quite poor, especially when screen off. So I was wondering if anyone has any suggestions, he has the 2.3 update, and said it made the situation worse.
Are there roms/kernels that improve battery life enough to make rooting/flashing worthwhile.
Thanks for any help.
Sorry If I sound like an idiot, I'm only familiar with things on the Hero, and Evo3D side of XDA.
I have been running the ERA Legendary rom and have been getting a full day with up to 4 hours of display time which for me is better than it was on Froyo
The epic touch battery (1800mah) fits the original epic (1500mah), and there is also a 1950mah slim battery out now, made by mugen for around 40$ that will also fit the original epic.
Sent from my SPH-D710 using xda premium
Most of the custom GB ROMs should improve battery life, cause they have tweaks to remove battery-wasting bloatware.
I'm running ACS ICS v5.1 and I get a full day out of it with moderate use which is way better than I ever did on Froyo.
Set all their syncs to manual, never or an hour.

I am syncing multiple email accounts on Legendary. Nothing special. This morning when I pulled my 1500Mah battery I was at 1d 14h total on time, display was at 2h 24m. I streamed lots of music and surffed, other then that not much, but way better then I used to get.
