Wow thats amazing... and your the first to make such a claim and have proof to back it up! @ days and change... wow! (hope its not photo shopped)... also running live wallpapers etc... very impressive! Still with 30 percent batt left?! What batery meter are u using btw... damn I think i might try that combo on my epic now...lol!
nice share!
but looks like very mild usage... what kind of batt do u get with moderate and heavy usage?

this week I'm learning how to flash roms, my phone got SIX hours with NO USE today. I'm fed up with it.

Sorry, I cannot do screenshot 'cos my phone is not rooted and complete stock everything, but as I posted in some other battery related thread my phone hold to 2 days 12 hours and 30 min with 3% left over Columbus day weekend.
BTW, TWS was over 50%

battery meter is in blue minimalist theme and not photo shopped i have posted other screen shots with 45 hours and so on. stud muffler if you cant go download shoot me to provide screen shots i dont believe you are getting that battery life especially because the sprint apps use the most juice and the galaxy rom is way more conservative scaling on the cpu. also no one else on stock is making the same claim as you are with that usage dont make claims you are not able to back up with proof this is android not apple. everything can be verified very easily. you do not need root for shoot me. if im not at my house where i have wifi my battery gets drained really fast on 3g with no data usage kinda sucks.

I see that the Display is at 11%. What kind of usage is this? The math says that is about 4.5 hours of being "on". I can see with the right setup those sorts of numbers being attainable. The difference being actually using the device a lot would kill more battery. What exactly is your usage pattern?
Edit: Whoops I didn't read all the way. Wifi is a big plus for battery life. I'm tempted to try out the Galaxy rom now.

so whats the point of this thread? I can do this too at my house, just hook up to wifi and the battery lasts forever, its the 3g that drains it as you said.

That's pretty amazing...I'm wondering what the 1 battery is? Car battery perhaps? LOL
I think the most I ever got with light/almost no use was around 19 hours with about 10-13% remaining battery. That's just a guess though...I wasn't trying to test the battery...just didn't talk to anyone for a day or use the phone for anything in general.

Somethings not right. Since when does the screen eat up less than any other process? Thats the top drain on all other epics

If you seldom use the phone for anything, the proportion of power used by the screen goes down, and so does total battery drain. Then you can brag that you got 60 + hours.

He still had about 4.5 hours of screen on time which is pretty damn good if you ask me. In my daily use I get around 13 hours of battery with a screen on time of about 2 hours, if I'm reading a book using kindle I get 9 or 10 hours with about 3 hours of screen on time.....so he has a higher screen on time than me and still gets like 2x more battery than me (I've seen his other screenshots) on average

I dont see where you got 4.5 hours of the screen being on
Sent from my GT-I9000 using XDA App

i also don't know where people are getting 4.5 hours of screen on time from the screenshot. It's not 11% of the total battery time on. It's 11% of the batteries overall use. It doesn't really have anything to do with the total time unplugged. Some fuzzy math going on heh.

I was at 42% battery when I just plugged in my phone tonight so it's charged up for work tomorrow.
It's not that hard to get these kind of numbers with light use.

@styckx:
How come yours saya "Unplugged for" instead of "Since unplugged"? Not saying its fake or anything, just never seen that before lol
Sent from my Epic 4G using XDA app.

Because in the SS it's charging and changes to "unplugged for". It saves the amount of time it was last unplugged for. If I unplugged it then it will say "Since unplugged" and reset the timer.
Yeah, not shopped, I'm not looking to score e-cred over cell phone screenshots.

I use my device so much my display & voice calls generally wear down battery in 6 hrs tops. used to be 10-12 but since di18 it sucks .. might be both updates idk. I'm anticipating some good reads to learn up on flashing & such so maybe ill be able 2 get better life. my browser speeds suck

Looks like a Day or Two of Airplane mode,
Im rooted and tweaked and get about 20 good hours of use-able time

I never understand y ppl brag about standby battery life. not saying op is showing stats based on that but to me its a pointless test when ppl do it that way.

Not impressed.

Does your battery drop to 0 that fast?
I have had a time where by battery dropped 15% within 1-2 hours, but then I was stuck on a certain percentage for hours.

Hello, I started a thread 2 weeks ago and it has some good info there. Take a look.
I update the OP regularly adding post made by others. No one has posted anything in a week. If you find how to fix your problems please post it there and I will add it to the OP. Its up to everyone to keep that thread alive.

I've had issues as well. Mine are related to GPS wakelock. Every fresh boot I will consistently get a partial wakelock of 100% because of the GPS. Simply opening Maps and closing it will force the wakelock to release.
I'm curious as to why others aren't having this issue, yet some of us are?
I've tried the EB01 modem as well as the DL09 modem and its the same results. Aside from this, battery life is great...

When you say 'idle' do you mean like zero apps running (like stopping everything running via a task killer). Then what,, like keep the phone's screen lit up by not letting it sleep and monitor the battery drain over a period of time? I'll have to try that and see how mine does. I'm guessing mine will prolly drop 15-20% as well if I have the screen lit for a solid hour.. hmm
I didnt really think mine was working 'bad' though, I just figured thats about what these batteries in these could do. I can make it though a day without a re-charge but I admit I have to budget my usage of the phone thoughout the day.. not using it for long solid periods of time and such.. If 15-20% an hour drain would be considered 'bad', how much should it drop in an hour to be considered working 'well' in your opinions?

Well I spent all day charging, using and then recharging my phone. it died in about 5:45 hrs of med to heavy use. I used the method outlined in this thread. http://forum.xda-developers.com/showthread.php?t=987529
I lost 5% battery in 45 min this morning which would have been nice but it was idle in my pocket. :-(
I gave up... reflashed 2.92nv and im checking to make sure its not having same issue.
If anyone has more suggestions there are now 2 pages i found for this problem specific to the facinate.

My battery is pretty decent after clearing battstats. Heavy use I'll lose about 13% per hour. Idle is decent, 3-5% per hour.
2.9.2 ec10voodoo

Ok I did a little test with mine - I set my LCD screen timeout setting to 10 minutes, turned my wifi and gps off (left the cell radio on), killed all apps that were running in task manager. Then I sat the phone down on my desk with the screen lit up and tapped the screen every 8-9 minutes or so just to keep it from going to sleep for one solid hour. I didnt do anything else with or use the phone in any way during this time. My battery dropped 18% in one hour. Think I'll try the batt stat clear procedure and redo the same test and see if its any different.

Mine is horrible. For some reason, it drains in proportion to my use. If I use it constantly, and hardly put it down, I'm lucky to only get 6 hours out of it.
I don't get decent life unless I put it in airplane mode, turn off rotation, and don't use it. Then I'm good for
16 - 18 hours.
WTF¿
Sent from my SCH-I500 using XDA Premium App

I can understand getting 6 to 8 hours if your a heavy user. but Im only concerned with my idle battery use. Juicedefender help some what. you can get it on the marketplace.
I'm still having the same issue with the nonvoodoo version. I'm still not sure how some users are getting over 40 hours of battery life.
as far as I can tell recalibrating my battery had no effect on the battery life. I plan on trying to recalibrate 1 more time in case I messed up the process. I will post my results in a day or 2. good luck to the rest of you. if you find anything out that may help me or anyone else please post it here

Only major thing I've changed in a while is I don't sign into Google Talk anymore. But that's got to generate minimal savings at best

My battery still loses about 1% per minute while I am online or on the phone
Another Fascinating post by my XDA app...

not trying to jinx you or anything, but don't get too excited til you've gone through a few charges... lately i've been getting exceptionally good battery life the first few charges on the ED01 roms, and after a couple of days, it gets significantly less battery, i don't really know why.
but i've always gotten pretty decent battery, so when i say i'm getting less, it means it's losing about 1% on standby as opposed to 0.5% and about 5-7%/ hr if i'm watching something or playing a game compared to 3-4%

1.2 had rotten battery life for me. Had it for a week. it would lose more than 15% sitting idle overnight every night. EC01 would lose 7% in the same conditions every night. Same apps installed.
1.3 is better. Still need a few days to see how much better. I don't think I am back to EC01 levels. That was the absolute best battery life I saw with this phone day in and day out.
Love the features of the community rom, just hope it passes the life test.

Synergy battery life

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 unplugged with my normal usage and still have 22% battery left. 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?

There's a great battery guide in the Q/A section, all kinds of tricks. Might find the guide to kernels there too, another way to drastically improve battery life. The new GB kernel sprint released is garbage, try netarcy-toast "brand" kernels

No where near CM7's battery life, but still very much a daily driver. I usually plugged up at around 40% battery after at least 12 hours usage.

Pretty decent for a Sense rom.

I've had my Evo unplugged for the last 2 days and still sitting at 43%. This is with sending about 60 texts, facebooked, got on frostwire for a bit, made like 12 calls, played a couple of rounds of Angry Birds and been on wifi about 95 percent of the time. Never has this happened with other roms. And I have tried a lot. Only thing disabled was 4G(none in my area)

Unplugged Sunday at about 2pm, it's now Tues at noon, I'm still at 49%.
Light to moderate usage since then, about 200 texts, a few short phone calls, and about two hours combined of facebook and twitter. VERY good life for 2 days worth of usage.

I just recently switched over from CM7 to Synergy RC1... I loved when I went away from Sense to AOSP and was reluctant to switch back. But very pleased and battery life I can confirm is excellent for me as well. My only gripe now is that I'm getting the darn unread email count showing up on my home screen icons even though there is no unread emails. I have found online that it is a known issue and mostly seen in 2.3.3? Can anyone confirm that?
Thanks!

I have tried several sense 2.1+3.0 roms, Virus Kingdom revolution, and mik g I have never been more happy than once I began using Synergy. Heck I even devoted a whole post on Google+ about it. Very stable and my battery is ridiculous. I took my phone off the charger at 6:30 am cdt its now 12:15 pm and I'm at 78%. That's with heavy usage. Great job devs.

When I first flashed I was goeeting okay battery life, the past few days has blown me away. I am used to seeing my battery drop like mad...but it does not do that anymore. I did nothing that I have not done on other ROMs, it just seems to work better after being on the phone a couple of weeks. This will be my ROM for quite some time now!

I'm really trying to get to the bottom of this display usage issue. My display usage stays extremely high compared to everything else. The more I use the phone, the higher it goes. Say if I use the phone a lot, it will be around 90%. If I barely touch the phone, it will go down to 50% but it's still a LOT higher than everything else. And it drains the hell out of my battery. If I barely use it I can get maybe 12 hours at most. If I do use it, I'll be lucky to get 7-8 hours.
It starting happening to me on MikFroyo but it didn't use to do it before. And now I'm noticing the same thing with Synergy. This is driving me nuts because it's keeping me from using my two favorite roms as a daily. I'll post three pictures. One is what my battery life/usage used to look like, one on MikFroyo 4.62, and one on Synergy RC1. I would really appreciate any insight to this.
Edit: It's only these two roms (that I've tried at least) that gives me this issue, and I think MikG if I can remember correctly. CM, Salvage-Mod, and a few other older Sense roms do not cause it.

This is with MikG 1.5, with my usual fairly heavy use.
AMAZING battery life, and 100% stable in my experience.
I have tried many, many ROMs and this one beats all.

no idea how people get battery life like that. i'm lucky to make it a 14 hours~ with similar usage

let me start by saying that i used to think the same way your thinking untill one of the guys on the synergy post broke it down for me. it's simple, you keep thinking that the display% is an issue but it's only a number and it doesnt represent your actual battery drain. if you hardly use your phone, lets say u make a couple of calls, check some mail and browse the web. well the percentage is correct, your display was on longer than any other application. so it's going to be higher no question. the real question is are you getting good battery life or not? i'm on synergy RLC1 and after some suggestions that i upgrade my PRL, PRi, and wimax. which i did, now im getting great battery life even though my display percentage is still the highest application.

That is only the case if it's maybe a little higher than the rest of the things. It's a percentage of what has used the battery. When the display is at 90% and everything else is at 3% or less, there is a problem. And no, I am getting HORRIBLE battery life. Like I explained, on ROMs that don't have the extremely high display usage I can get 20-30 hours on one charge. The way the battery drains when I'm using it is extremely noticeable. The picture I posted that has been on for 14 hours with 48% left, that's how my battery usage should look. Granted I hadn't used the phone as much as normal that day, it still would be around the range of everything else.

Bi-Winning v3.0 + Bali v1.8.8UV = 48 hour battery

I thought I would throw this out there just because I found it quite amazing after a year of tweaking the vibrant. I just decided to swap back from Simply Honey to a 2.2x rom because I was having issues with reboots while on the phone. I had been using Bi-Winning prior to installing SH-3.9 so I went back to that but this time I installed the Bali v1.8.8UV kernel after reading some tips. I'm getting 48 hour battery life on moderate use where I was getting 18-20 before. This Bali kernel is something else. I think this setup is a keeper.

you just put on bi-winning and bali or did you undervolt as well? settings would be great cause with a 48 hour battery thats enough to get me to go back to froyo haha especially now that netflix is on froyo as well

I just put bi-winning on it, rebooted, put bali on it. I'm trying to think of anything else I did but I can't. I installed this combo friday night and I thought it was a fluke or I had forgot that I had plugged it up sometime over the weekend when I woke up monday morning with 25% battery. I made it from tuesday morning @ 7:00 until just now with 40% left. I Just plugged it up and I'm going to make an effort to actually benchmark it this time as I don't believe it either. I also just put the same combo on my wife's vibrant to see what kind of resultes it gets.
Am I subconsciously plugging my phone into the charger?

Yep, I get similar results. Currently I'm on ZenDroid 2.0.1 with Bali 1.8.8UV and I'm sitting at 35% remaining and 48 hours since unplugged. Light-moderate use I guess but with some gaming, lots of texts, several 15-20min calls, and wifi on 24/7.
ECOTOX's DragonMODz ULP kernel performs very much the same as well. I have a hard time picking between the two.

wow thats awesome, just checked out bi-winning and there are some decent themes as well. So this is with data and sync on as well?

I'm currently running on Asgard 3.1.2 (Same devs, right?) and it's running awesome.
Thought I'd upgrade to Bi-Winning 3.0 on my Vibrant.
I'm kind of new to this.. so since I'm on Asgard running the Bullet Kernel, all I have to do is flash Bi-Winning via. Odin3, right? If so, will I lose any of my apps/data?

Indeed. Full Google account sync and Facebook once daily. Data is on and using KB5 modem.
Oh and I've also started using the Screen Filter app to reduce screen brightness even more than the android minimum and it seems to be helping a lot as well. Check it out.

Just wanted to add a testimonial to the OP since I'm running exactly the same thing. Just Bi-Winning and Bali 1.8.8UV, it already comes undervolted by -25 I believe and I'm getting similar results on battery life. Kernel and ROM go very well together and it's quick, responsive and very very smooth. I'm using it with ADW EX launcher by the way.

flashed both and so far so good, battery is a little better but nothing as significant as 48 hours, do I have to wait a day or 2 to let it settle in first? Cause I know when i was on cm7 they said let bali run for a day or 2 then after that youll notice the difference

No pics, no proof

Anyone of yall use GPS at all or just moderate use....

The stock battery will not last with more than 2.5 hours (+/-) of Display use, no matter how you slice it.

Well, that's just plain wrong. I've been gaming through multiple episodes of "The Good Wife" with my family and my battery is down maybe 20%.
Now, 2 1/2 hours of an all white background on maximum brightness might kill your battery (flashlight apps), but not typical use.

I don't know exactly what "gaming through multiple episodes" means but a screen is a screen. There's no software affects the display's energy use. Like I said, the +/- depends on your brightness settings and exactly what you display on your screen. I challenge you to show me battery usage screen shot with more than 2.5 hr of display on time on a single charge (with stock battery). I don't doubt you can push 48hrs on a single charge, but chances are, the display on time is less than 3 hours

Does anybody have some screenies to prove it?

I have the exact same setup and my battery life is nowhere near as good. And this is just with data on, no bluetooth, wifi, gps, sync, etc.

Echoing the sentiments of others... Seeing is believing screen shots guys. Thanks

I don't know exactly what "gaming through multiple episodes" means but a screen is a screen. There's no software affects the display's energy use. Like I said, the +/- depends on your brightness settings and exactly what you display on your screen. I challenge you to show me battery usage screen shot with more than 2.5 hr of display on time on a single charge (with stock battery).

Well, you're in luck! I'm breaking in a new 1700mah battery and want to drain it down to 20% anyway. I'll do so with the screen on my default homepage instead of using the flashlight app. I'll run a stopwatch app in the background and get you some numbers. If you're right, I'll eat my hat!
Then again, since you said +/-, even if it lasts 72 hours, you're still right. It's just 2.5hrs +/- 69.5 hours

I'm the OP and for the last two days my battery has not been lasting nearly as long. Of course I have gone for light/moderate use to heavy use but also I'm seeing it chew through more battery when idle. I'm not sure what has changed to make this happen. I've kept wifi off. I don't think this had anything to do with it but it seemed to start using more battery as soon as I installed the google maps update but the battery profiler doesn't say anything about maps. Oh well...

Well, after 2hr30min, my battery is at 84%. Sure, it's a new battery, and the 84% is probably a little inaccurate, but I haven't stopped the test, so we'll see where it goes from there. Wifi, Bluetooth, and Data are on as well as several widgets on my homepage. I haven't done much with it except keep the screen on indefinitely and send/receive a few texts.
Anyway, the proof is in the pudding. Mmm... pudding...
