[Epic 4G General] prfella:
Thank you for your helpful reply kennyglass123...and bless your soul for reading through that whole post!

Sorry about that I forgot to mention in my original post that I am running a non rooted phone and stock rom. And to your question about whether I am using any social networking apps, I dont use any social media networks, Im an anti socialite, if you will. So I definitely do not have or use any apps like facebook, google +, twitter or any of those. I did download spare parts and even though my phone is not rooted, it still tells me whats using my battery.

The thing that I have heard that causes a problem is when spare parts lists something that is doing a partial wake lock. Right now the top thing that is doing that to my phone is Juice Defender. Could that be bad?

OK after another day of usage I have something to report that may or may not be exciting to you guys. Let me give you the rundown:

at 12:00 PM I unplugged my phone from charger. It said 97%. for the next 15 minutes or so I tried to fiddle with some settings to see if I can save a little more juice. Again all the settings that I had in the previous post I have applied here as well.

after those 15 mins The battery managed to drain to 89%. All with just trying to disable stuff. I dont know about any of you, but to me that's very, very...very bad. Considering NOTHING is enabled on my phone, and i was underground as well, so no connection, I already had it in airplane mode just to be sure.

So 20 mins later I thought of something I had read a few days ago. There was a single post in a battery saving thread for the epic 4g on androidforums.com. This one poster said that he had a theory that maybe the option "Power Saving Mode" was actually doing more harm than good. Now when I read it I didnt pay much mind to it as it was just a single post in a thread, and no one had even replied to it. But at that point I was willing to try anything. So I disabled it.

These are my stats with every setting the same as stated in my last post, plus disabling power save mode.

at the time of this post it is 12:47 AM

Since unplugging....20 sms messages, one 60 minute phone call, and constant checking of the time with the screen still locked.

13h since last charged. Battery 60% ...

Only 40% Drain after 13 Hours! Now I dont know about the rest of you guys, but thats a HUGE improvement for me. Now I do acknowledge that it isnt great, seeing as everything on my phone was disabled for the whole day besides 2g, but still, lol.

It appears that the power saving mode actually drains more battery than it saves, and it is counter productive to what I was trying to do. But I can honestly say that I had no idea that it would have that much of an impact on my battery life. I researched it and it seems quite a few people agree and have had similar results.

Now I ran into a thread while researching the very same power saving mode, and while there are a few things to consider, some users were able to get 114 hours out of the Galaxy S phone! like wowsers.

These are the important things to keep in mind. One, it is a post from 2010, two it is not for epic 4g specifically, but for all Galaxy S phones. but still a Galaxy S phone, which is what the Epic is. The epic having a keyboard might have an effect on battery that the other phones dont have deal with. and three since it is a year old, this is before froyo, and I have heard that froyo brought some battery drain issues when many people updated to it.

Again, I apologize for the long post.

ugh I tried to link the thread but new users arent permitted to post links, in addition to images, great!

so I will tell you how to get there manually: go to samsunggalaxysforums.com, got to tutorials, and go to "how can i make my battery last longer!"
