Battery issue update.
Went back to Sprint last night to let them know how their fix was working. They decided to go over it again because I told them about having to toggle airplane mode, or do a PRL update. What they found was, whenever you access a data channel other than 3g/WCDMA, media hub restarts. That is, if you turn on 4G, or wifi, media hub will start. The only fix at this point is after you use 4G, or wifi, go back into running services and shut it down again. The DRM should not be starting with it but check when you close media hub to make sure.
As far as the airplane mode/PRL, what appears to be happening is the data channel opens for media hub and stays open. You should only have to toggle on reboot, not every time you close media hub. They put in a ticket to Samsung and said this should be resolved with an independent update, or with 2.2, which according to them is due out next month. Hope this helps those that are killing DRM and media hub but still having a drain issue.
So to be clear, anytime you access any data off 3G/WCDMA, be it 4G, wifi etc. Media hub will open and will have to be manually shut down again.

Mine does - I discussed this ad naseum with my tech - they have had no other complaints than mine, no information or communication from Sprint, no idea what was wrong except to hard reset or exchange.
I have turned so many things off and on my phone, I'm not sure if I screwed something else up - my music player doesn't work with headphones. So I think I am just going to exchange just in case since I am in my 30 days. I do not feel like fighting this forever, and some do not have the issue.
My thanks again to everyone who jumped in and shared, I would never have found these issues, I was just disgusted. I'm knew, so what a way to learn Android!!

I deleted media hub and I kill drm at boot. It does not restart.
After rebooting this morning and once again verifying the phone does sleep, 5 minutes ago something triggered my phone to once again stay awake. I then proceeded to kill every single program and running service but it still remained awake.
I just rebooted which solves the problem but only temporarily as I have found.

Glad to hear it. All the thanks go to three Sprint engineers. Mark, Tim and Jose. I don't know their last names but the fact that they took a total of five hours of their time to dig through the entire system bit by bit to diagnose and come up with a fix. They were very attentive and interested in making it work as it is supposed to. Not knocking any other carrier but I can't really see that happening anywhere else. Also to the rep, Kathleen, (I think was her name), that contacted them in the first place, rather than just tossing me a battery or a new phone just to get me out the door.

I exchanged my epic for one of the same, the last one was having overheating problems but the battery wouldnt drain like the new one i received. also takes 3-4hrs to charge, which in my opinion is too long compared to the defective overheating one that only took about an hr and a half. They both had the update and I never took off the DRM thing. I have a feeling this is a Samsung battery issue. What do you guys think about this?
Also. the new phone's battery is only lasting about 4 hrs and thats was with no phone time, all of the wifi, bluetooth, 4g, and gps off. All i had used it for today was txt and google voice(more txt).
I believe battery issues. What do you?

I want to give Flynlow much credit for his finding on the DRM app and posting it on here.
I had posted before in another thread on my poor battery life, even after killing the DRM application, toggling between airplane mode, and making sure 4G/WiFi was off.
I took my phone yesterday to the Sprint corporate store, after calling tech support to document my issue with my phone battery and to setup an appointment at the store. They tested my phone and battery, and my phone test fine. My battery failed miserably. They gave me a new battery and were kind enough to call me, at my office, when my phone was ready for pick up. The battery was fully charged when I received my phone.
I am pleased to report that after closing Media Hub and DRM app, as well as toggling the airplane mode on and off, I now get well over 12hrs+ of moderate to heavy usage(phone calls, email, texts, web surf) on my battery.
So far today, I have been unplugged for 13hr 11min 35s and my battery stats are as follows;
Voice Calls: 67% - 2hr 7m 1s
Display: 22% - Time on 1h 47m 39s
Cell Standby: 5% with Time without signal at 3%
Phone Idle: 3%
Bluetooth: 2% - time on 7h 19m 39s
I now have 24% battery left.
So have your phone and BATTERY tested.

flnlow, that was great of you to thank the engineers. Where were they, local or somewhere in Sprint.
I have been to two service centers, I am the only one complaining. They will not change out my phone since they can find nothing wrong, smartphones suck battery, etc., with it within my 30 days. I was told the phone is too expensive for Sprint to trash, and I said it was too expensive for me to buy and keep since it went to hell after their update
So I did a hard reset to see if something was conflicting, firmware maintained update. I am still sucking battery, so I'm timing the loss. Media Hub, DRM Stoage, and for some reason Sprint Hotspot (not signed up nor have used). Lost 40% in 5 hours with nothing on and light use.
Tomorrow, I'm going to turn these off and document battery. I did lose my
temper with the above comments, so if you say Sprint's Corporate Engineers are aware, I will probably carry my netbook in with my figures and ask for another phone. However, I'm concerned it might do the same . . . if it does, my husband's Evo is going 1.5 days on same setup, so might have to switch. Like mine better, but not living for chargers.
I live within blocks of the Sprint headquarters in Overland Park, KS. I always use their on campus store since it's so close.
To answer a previous question, there is no set length of time I charge my phone. Usually plug in when I go to bed around midnight. Unplug when the alarm goes off at 630. Last night went to bed at midnight, woke up at 100 when the screen came on when it was full charged, unplugged then.
here are my stats now:
18hr 54min unplugged
It has been working absolutely beautifully for me since the DRM kill. This is better than my blackberry batteries ever were and easily puts my Evo to shame.

Wow, @flynlow and all, thank you for all this incredibly helpful info. I just got my epic yesterday and have mostly enjoyed it, other than getting only a precious few hours on a charge. Looking forward to firing it up and making these fixes--when it FINALLY finishes charging (mine take a coon's age to charge, btw)--and hoping that it will give me the battery longevity you guys have begun enjoying. Cheers to that, and here's looking forward to the 3G upload fix (hopefully without borking our batteries with some other new glitch).
Out of curiosity, I'm new to Sprint and new to Sammy. In you guys' experience, do you think we can expect to be pulling these bootleg solutions for the next two years, or will they roll out some healing goodness in the next month or two of OTAs?
