I wouldn't suspect the ROM, but rather battery, charger, cable, port... store can check those things out for you.
In re to what you can do in theory, modern ROMs/android OS handle things pretty efficiently so I don't think it is something you have done - that is if you are not overclocking and leaving it on your oven when cooking.
Make sure you are at like 3 percent before recharge. Do that a couple times and out will restore your battery, worked for me

Wow I hope your battery worked itself out in the end. I just have another question. How long should a stock MyTouch 4G battery last?
Even before I rooted my phone and tried a bevy of roms known for their battery life, but I never get passed just about 9 hours. I used my phone moderately text messaging, surfing periodically and playing music and podcasts in between classes. I have turned off auto sync and did the battery stats wipe.
Just wondering if my expectations are too high. Nine hours is nice, it gets me through the day but then I lose it for a couple of hours in the afternoon to charge up for the remainder of the day.
Thanks again guys!

Try TDJ's CM 7.2 kang. I have gotten over 24 hours on that ROM.
Battery life is like fuel mileage. Its how you drive it. One person may get 17 mpg on a car that someone else gets 22 in. Screen on time is better to go by. A good ROM/kernel combo will get you around 4 hours screen on time. Maybe more.

As we all know, the Galaxy S uses a Li-Po battery.
Having previous expirience with those batteries (R/C Helicopters), i know that they require 5-10 cycles of full drain-full charge to reach full capacity and start their normal life cycle.
Not too long ago, there was a thread complaining about battery life here, but i think it was due to people checking usage time on the first or second charge only.
In this thread, i'd like to hear your opinions about battery life, but please-
Only those who passed 5 FULL drain-charge cycles, reply. We need some objective information about it.
Personally-
I'm after my 4th charge, and already seeing HUGE improvement. When i recieved it i barely managed to go through a single day, and now i'm almost 2 days since i last charged it, played some games, browsed a little, made a few calls, and i'm still over 65%.
Waiting to do 2-3 more charges and reach optimal state to see what it's worth.
Mine is a Li-Ion and lasts about a day with almost constant use.

You are correct in that initially we were told the battery type would have been a Li-Pol.
However, since the phone's release it has now come to light that the battery is in fact a Li-Ion.
I made a post that mentions this here if you wish to have a read.
I’ve had my phone approx 2 weeks, so I’m on my 5 or 6th battery recharge. My phone has been on for 1 day 20hrs now. I’ve talked on the phone for about two hours and surfed for about ¾ of an hour. Wifi has been on all the time – Bluetooth about 3hrs. Current battery level is 70% - I must say after all the gloom and doom re the latest smartphones I’m more than happy with the battery life so far and does seem to be getting better all the time.

In contrast I have had my phone since Thursday... I've charged it 4 times in 48 hours so far. I am using it a lot and am hoping I get thee performance rise soon.
Crabby
I'm pretty sure it will.
When i got my phone i charged it to full, and before the day ended i needed to chrage it again.
And now:
Last charge was thursday morning (GMT+2), and now, after 2 and a half days, i still have 40%.
I could probably go on for another full day.
My first few charges barely made it through the working day, but now the phone still has plenty of charge after 24hours. Although right now is an exception, as the lady is playing Abduction on it and will probably keep at it until the battery dies
She really should get her own Galaxy S. Although we're waiting on some GPS improvements before replacing her phone, she cant afford to get lost.

I got my replacement SGS today (had to send the original one back as Carphone Warehouse messed up the order so had to send everything back just to get a new SIM) and been hammering it for 14 hours, literally 80% of that running games, using WiFi, bluetooth and GPS and I only got it down to 25% and hadn't even charged it to 100% before I couldn't wait any longer. If the battery does get better after the initial charge, I will have no problem with this phone.
Further to my earlier post...
Charged the phone to full before bed last night... All of the power widget functions of two exchange email accounts and hotmail updating every hour.
So with no other use for 8 hours the battery was at 91% when I woke up. Battery status confirmed that 57% had gone on standby and 29 % on idle
So... Presuming this bsttery use is constant when idle... My phone will be down to 70 % by 24 hours with no use?
Crabby
It varies greatly according to reception.
Good network coverage= less work for the transceiver inside the device=less power drain.
It's not really constant.

Is this something you do as routine? I don't know if I have the patience to do that.
And my signal was 5 bar edge signal for my 'test'.
Since this morning, I watched 90 mins of video, surfed for 10 mins and made a 5 minutes voice call on the train... By the time I got to work, the battery was at 53%.
I don't feel my phone will last my journey home at 6 tonight, so I have had to put it on charge again.
But still... on 3 days old...

I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??
Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.
I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!
I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.
ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.
Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.
DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.
I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.
Ok my gf has gotten the surround for xmas. I wanted to see others battery usage. In essrnce how long does your battery last. Hers seems to die pretty fast and was curiuos if this is common for these phones. I would give an estimate of the time but cant atm bit will tm.

Lots of complaints on the web about this. I've had mine a few days. In my experience, like all smartphones, doing a lot of stuff (like, the things you'd do with a new phone the first few days you have it) will drain it quickly. Once you settle into a normal usage pattern, you'll probably see an improvement.
The "bad battery life" complaint always seems to come from people the first few days they own a phone and are basically turning it on and fiddling with it every 30 seconds. When used like a smartphone is normally used, you shouldn't have a problem getting through a full day with it.
Oh i know bout battery life. I got the incredible. Only 12 hours charge(but i use alot).
Thanks for the response though. Just seeing if the fast battery drain is normal for this phone. She is deffinately not a heavy user besides txt. But it seems a fast battery drain is normal. So its cool
Do you use a battery charging technique called "bump charching"?
Sent from my ADR6300 using Tapatalk
Battery gets conditioned as you use it. Just keep using it and in about a week you should get normal battery life. The issue is that the os handles both charging and discharging so after a few uses the battery and the os reach its peak performance
I believe it is alteady beggining to condition. She's just not used to having such battery drain. Its seems more stable in its level of drain. I also had her "bump" charge. To get a full capacitu battery. I notices these phone only have a 1250mwh batterys.

Battery life is horrid compared to the Fuze. I get anywhere from 12-14 hours before needing a recharge and I have been several charge cycles. I suggest turning off data connections when possible and using wifi.
Better Battery life
My htc surround also consumes a lot of energy. So today I entered in SETTING > CELLULAR > and turned OFF data connection. I think this is change may save a lot of energy, at least I can use this strategy whenever I dont need the data connection.
Lets see what happens
1500mAH Batteries on eBay
The stock battery that comes with the HTC Surround is only 1230mAH (or something on that order). There are several sellers on eBay who sell an aftermarket battery like this one: cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130467721933, which is actually a package of three batteries and a charger for $12.99 with free shipping - perfect for me and my wife to use and always have a freshly charged spare.
These batteries should give a little better than 20% improvement in battery life over the stock one. Does anyone here have any experience with them?
Sorry for the cut and paste link - as a new user I am apparently guilty of spamming before I had even thought of it (like Minority Report).
As of now she gets between 2 to 3 days use with medium txting.
Can any body else report on their battery lifes.
Also has anyone bump charged and seen an increase in their battery charge.

Good Battery Life
I use my data connection constantly, never shutting it off. Also, I spend about half of my day in the center of a building not getting any reception, consistently going from an area with service to one without, which has the phone searching endlessly for a signal. For the first week, the battery was drained within 12 hours, but now in the second week, I have about half of the battery left when i get home, play games, check email, do EVERYTHING, and probably have about 25% when i get into bed and only plug it in as I go to sleep. On previous phones, I would have been able to do this two days in a row.
I came from a Tilt 2 and ended up getting an extended battery (making the phone HUGE), though I see no problem plugging the phone in every night. Battery life is getting better and I'm not sure who NEEDS to go multiple days without a charge. Either you make your phone huge, or you plug it every night right next to you anyway.
I am very happy with the phone, and can't wait to do more with it.
I know it isn't normal.
I swapped batteries two nights ago. I have spare parts installed. My wifi has been on the entire time. GPS was on for 6 hours today when I forgot to turn it off. I work in a basement.
I'm about to go for a walk and listen to music, but I'll be back in an hour. Ask your questions. I don't understand why some of you are having such a hard time with your battery life. I'm not doing anything too weird or even putting my phone in airplane mode.

Normal battery. Running Mammon's Bonsai4All. I've talked on the phone for about an hour total in the last two days. I played games for maybe an hour. I used the gps for a while today, then went back to the basement. Didn't listen to much music before tonight. Bluetooth headphones took it down a bit. A little less use than normal. Usually I swap batteries once a day.
That's not a whole lot of use. I've gotten up to about 35 hrs before on a charge but I used it more thn that.
sorry to thread jack, but is there a tutorial for spare parts for optimal batt life?
I have Bonsai as well but only get around a day at best with minimal use.

You get about the normal. I think it's actually considered average since about 16 our so hours is what I get too. My guess is that these folks put their phones in a cryostasis chamber to achieve that type of life. However, I believe the op mentioned "replacing" the battery. I wonder if that was a brand new one or what?
I normally get about a day of use, with a bit more use than what got me this much uptime. I have had some new things to work on at work and new games to play at home, so I haven't been on the phone for things as much as usual.
I do have 3 batteries (all standard Samsung batteries), but I randomly get unexpectedly good battery life even with normal use. I think one of my batteries is holding more charge than the other two.
I'm shocked you guys get such good battery life.
I went back to DI18 for a bit after DK28 to see how if battery life was any different. I'm running stock everything, no DRM killers, just the "Samsung Experience" with Launcher Pro.
It's sad and embarrasing. I'm lucky if i can pull 8 hours, unlucky if i stream 4 hours of pandora and its dead. I have 2 batteries and I've gone through both in the same day while at work listening to pandora
I get a full days use: on stock eclair 2.1
I use Mobile ap for like and hour and half
Talk on the phone for like an hour a day
Text like 100 at the most a day
Browse the web on wifi for like 3 hours at home
Using these after the day is over im at like 30 percent.
I'm at 72% right now, 8 hours since unplugged.

I do something similar to that third option. I have three batteries and two chargers (one for each battery that isn't in my phone). I charge in the charger until it stops, and then about half the time I pull it out and pop it back in to bump charge it. I make sure to bump charge before I recalibrate. And I recalibrate one of the three batteries every two weeks or so, so they are all done every six weeks.
so i just got the epic like 3 days ago and i noticed that it darins the battery super fast unlike the mesmerize well today i had it fully charged and i unplug it from the wall and then sat it on the counter and took a shower and then i checked it and it was already on 90%..... its only be like 5 mins give or take lol i did the calibrate trick to and everything was on 100% when i did it and right when i turned it back on after the wiping the battery it was already at 98%
so do i have a bad battery or umm is it just me lol the only thing i did on the phone was root it and turned it into EXT4 and then installed the franken rom
Get used to it. Buy spare batteries.
It is Samsung's crappy software probably. Make sure you do the airplane mode trick and kill the drm service. Also make sure any apps you installed are not misbehaving. Battery life is still going to be the worst of any phone out there though.
I have had my Epic for about two weeks(I came from a Moment, then a Transform). I havent run a stock rom since I got it. I use my own modified DK28 rom. I have no sprint bloatware. Average use my batter lasts 14-16+ hours.
Im guessing probably around 45 mins of calls, and 100+ texts, and 1 hour or so on the web/market is my average use.
I found when I first got my phone I was using it constantly checking out all the cool things it could do. Four or five hours with the display on drains it pretty fast.
The battery I have in now is showing 18h 4m since unplugged with 24% remaining. Display on time is 2hours 28 minutes, which is taking up 86% of the battery.
I purchased a wall charger with two spare batteries off ebay for $10. The two spares last almost as long as the stock battery but not quite. The wall charger seems to charge the batteries better then the USB port on the phone.
Definately get some spare batteries and make sure to carry one around with you. One fits in your wallet with no problems. As I have told people before you are basically walking around with a handheld laptop.. Be glad we get the hours out of a charge we do...
Also baffles me why people want dual core phones.. They think batteries get drained now, wait till the next generation phones come out. Unless they add much larger batteries then those things will go quick.
My battery life has gone from below average to 'functional' after rooting and installing JuiceDefender. I had Tasker running similar scripts before but eventually replaced it with JuiceDefender.
Root: Nebula 1.07 EXT4. Removal of bloated Sprint software and non-essential apps.
JuiceDefender Settings:
Controls > Data, Wifi (AutoDisable), AutoSync (Ping)
Schedules > Schedule 1hr, Night (12am --> 6 am)
Triggers > Battery 15%, SCREEN
NOTE: System Panel confirmed that CPU now idles at 1%-3% during screen-off with the expected jump to 10% during the 1hr interval syncing.
18 foot long charging cable then just keep it plugged in. Get the portable charger that you can charge while on the go
Or just close some widgets and apps using the internet and all the 4g/GPS etc. to save battery....
Well I just thought the epic use as much battery as the mesmerize and my mes was really good

Probably the Time without signal bug in the radio firmware. Read this post for info on the workaround. My phone went from 10 hours to well over 24 hours by following these steps. The short answer is, every time you unplug the phone or reboot toggle airplane mode on for 15 seconds.

Yea battery sucks, welcome to the world of monster smrtphones. Anyway, once we get source for 2.2 (IF we ever do I should say), devs can optimize the kernel and hopefully give us better battery life. If you care about battery, stay on 2.1 and flash a custom kernel. Good luck tho, best option is rly to buy a spre battery, as has been suggested already.

I just some of the upgrades in the development forum, and even added the Midnight Rom, and my battery is doing better than what it was before. I am very impressed with the things I added to my Epic 4g and this site for all of the awesome info.
