I have read and learned about this phone (stock, nonrooted, with stock 1500 Batt). I am running Juice defender (purchased pro level, and app killer). After reading a lot on this and other sites I found out that the running services DRM is the one to shut down under the application tab then into running services. I have used the phone for 13 hrs yesterday and now for all of today (so far 9hrs) and have 3/4 battery full. I have been on web (wifi stays on) and taken several calls yesterday and today. JD is taking some credit but the DRM shut down really helped with 2.1 OS

How To Use Vanilla Android Launcher Instead of Touchwiz
So playing around I gigured out how to switch it:
Press Menu > Settings > Applications > Manage Application
Press Menu > Filter > All
Scroll down to TwLauncher and tap that, then tap Clear Defaults
Press Home and you will be prompted to select Home (Vanilla Android) or or TwLauncher (Samsung TouchWiz). Check "Use by default for this action" to set Home as the default Launcher if you like.
If you ever want to undo the process, simply repeat the process but go to Home instead os TwLauncher.
Enjoy.

Epic 4G Airplane mode overnight
When I go to bed at night, I set my phone to airplane mode (if I set an alarm), or just turn it off. It really stops the overnight battery drain.
Satisfied with Battery Life!!! Epic 4G
Like a lot of folks, I have been scouring the forums looking for tips to improve battery life. I've finally got mine to a point that it is fantastic! Here is a list of things I have done that have helped. Please forgive me if a lot of this info has been posted before in various threads. I just wanted to combine it all for those new to the forum.
The Solution:
1. Use the Airplane Mode tip after any reboot. (Put the phone into airplane mode, then turn airplane mode off.)
2. Download Switch Pro (or a similar app,) install the widget and include 'Data Connection' as one of your widget choices.
3. Turn off data connection unless you need it. (Keep in mind that you do not need a data connection for voice calls or text messages.)
4. Turn off wifi, gps, 4G, and bluetooth until you need them. Switch Pro is also great for this as it gives you tons of options for things to switch on/off.
5. Use wifi instead of data connection (3G) whenever possible. Wifi uses far less battery than the radio searching for a 3G connection. Go to wi-fi settings > advanced > and set wifi sleep policy to 'never' and de-select 'network notification.' You don't need the phone constantly scanning for open networks. When you need one, you will find it!

Epic 4G Battery Life extension
This is in regards to Samsung Epic 4G running Android 2.1 (Eclair).
Battery life can vary from 3 hours to 12 in stock configuration. Poor. 24 hours is easy and 30+ is attainable. Read on:
{Everything here I learned from other posts and experimenting. Not claiming any credit. Read ALL OF THIS POST. I read dozens of posts and condensed it to this one for YOU!}
A note regarding 3G, 4G and cdma: 3G and 4G are DATA SERVICES ONLY! These are NOT your phone and text services (cdma). They ARE your email and voice mail notification services (as well as web data, obviously). Turning all of these services off makes your smart phone a dumb phone. This is VERY appropriate during a movie at the theater, during work hours, while commuting, etc. However, I like my phone being a smart phone. So keep in mind that the WiFi uses LESS battery than the 3G, which uses less than the 4G. Use WiFi ALL THE TIME when in range INSTEAD of 3G or 4G (which are MOBILE data services---like when you are MOBILE). I use WiFi only, turning it off (if I remember) when commuting. Really--3G and 4G are services that most users will rarely use! These are only useful for when you are outside, travelling, in the mall, etc. Again--MOBILE data services. WiFi is in most of our homes, schools, and workplaces.
**A note regarding the radio/battery "Airplane Mode BUG" in the Samsung phone. The Epic 4G needs a radio reset ONCE upon reboot to reset the radios. This is a known bug and if not reset the cdma will constantly hunt for service, draining your battery. This can account for HALF of your battery drain!!!!! To verify this--go to settings->about phone->battery use--and look at battery uses. Number one on the list is the Display at upwards of 50%. (should be). Number two is probably cell standby. This number should be UNDER 45% (assuming you have had near-constant signal). Mine is currently at 16%, but runs at almost exactly 50% if I don't address the bug.
---> To reset the radios: With phone running, hold the power switch on the side of the phone for a couple of seconds until you feel a slight vibration. A menu will pop up. Click on Airplane Mode. This turns ALL radios off. Repeat. Click on Airplane Mode to turn radios back on. This must be done right after restart, once. Extra times wont help or hurt.
Now that we have the preliminary steps and info covered, follow these steps to further extend your battery life:
*Kill DRM services (this is the media hub stuff that no one has ever used but it eats a lot of battery). Go to settings->Applications->running services and look for DRM Services and DRM protected services. Disable both of them. You will get a warning about making media hub not work. That should be fine. Kill it. This is a BIG DEAL! Don't skip this one!
*Download, Install and run, in the default configuration, JuiceDefender (free, not beta (beta crashes)) from the Market. Just install and run. Nothing to really set up in the free version.
*Press and hold the home screen until the menu pops up and click on "widget" and install the "Toggle mobile data" widget. This widget installs when you install juice defender. This widget puts a toggle on your home screen allowing you to turn off the 3G radio. Click the toggle until it turns red and your 3G turns off. (Turning WiFi ON turns 3G off. Setting WiFi to "sleep never" will keep it on while keeping 3G off. I prefer toggles on my home screen that change colors. Simple and I am in control.
*Download and install "WiFi Toggle" from the Market Place. Install this widget on the home screen near the Mobile Data widget. It toggles WiFi on and off and turns colors when off and on. (Yeah-the phone has a built-in switch. But this widget is simple and installed right next to the 3G widget it gives you simple, verifiable control over your radios).
*Background Data and automatic sync: This option (found in settings) uses battery when the phone routinely syncs with servers seeking updates on new messages, emails, etc. I prefer to leave mine on and keep my phone smart. It will drain a bit more power. If you want to micro-manage, keep this off at all times and manually check your email, etc. (If WiFi and 3/4G are toggled off, background sync can't do anything anyway...)
*Keep your Display set to auto time-out in a short time. Keep brightness to auto or low. Display is your NUMBER ONE battery killer. Oh well. You gotta use your phone, right?
*Task Killers: a controversial subject. An important consideration: Most services, applications, etc running will show up in Battery Usage monitor as "Android System." My Android System is currently using 12% of my battery. I DO NOT run an automated task killer. Yeah--Android keeps a bunch of crap running in the background. And if you kill it all the time you can reduce your Android System battery use from 12% to 10% gaining a whopping 2%. If you manage 30 hours out of your battery this could get you an extra 40 minutes of battery time....
Consider that automated task killers ALSO use resources and wake the phone up to kill processes.
However, it is nice to be able to shut down all non-essential processes when necessary (during a near-lock up, etc). I use System Panel Lite for a system monitor and task killer when necessary. You have to set up exclusions for this program. Use your common sense and exclude everything that says Android, and Swype, etc. Don't exclude Media Hub, Amazon MP3, etc. When you want to, you can select "end all" from System Panel and end everything BELOW the level you select (should be below Excluded Apps generally).
That's really it. Reset the Airplane Mode. Keep 3G and 4G off unless actually using them. Use WiFi. Kill DRM services. Keep the screen off when you can. Use JuiceDefender. Don't worry about automated task killers.
I doubled battery life in my phone immediately. The biggies were the Airplane mode bug (dropped cell standby use on my phone from 50% to 16%!) and turning off 3G. JuiceDefender got me a bit more. These simple things will get you a lot of gains.
Worry yourself to death with app killers and auto sync settings and micro-manage your phone and you can get life upwards of 35 hours...but I fail to see the point. This is a "charge every day" phone. As long as it works for 24 hours, everything is good. These tips should get that for you.
However--keep in mind: if you sit there and obsess on your phone (you are a teenager) you are gonna need extra or extended batteries. I am referring to NORMAL USE in this thread. A few texts in a day, checking the web here and there, playing Pandora on the way to work, a few phone calls, a few emails. Basic use. Executives attached to their phones and teens probably can't get desired usage time out of the stock battery.
Good luck.

Keep the Touch-Sensitive buttons ALIVE
A real quick poke through the phone revealed a very easy fix.
The path is here:
Settings[Sound & Display[Keyboard timeout[Same as Screen timeout
=my screen timeout is 1 min=
As we all know, and I verified this. The keyboard backlight only turns on
when the slider is open. Now the touch-sensitive buttons will infact stay lit
as long as you would need them, while the screen is on!
Life just got a little easier B)

How to successfully Mount the Epic 4G
It seems that the Epic 4G refuses to work with auxiliary USB ports, possibly cause it's not getting enough power. So make sure to have the Epic 4G USB drivers.
http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=US&CttFileID=3185503&CDCt tType=SW&ModelType=C&ModelName=SPH-D700ZKASPR&VPath=SW/201009/20100901010102890/Samsung_Mobile_Driver_V1.3.800_For_SPH-d700_Epic_4G.zip
Then make sure you plug in the USB cable to a main USB port, not an auxiliary one (depending on your computer, most likely in the rear of the case).
