Since the release of the DI18 update I haven't noticed much difference between killing the DRM service and leaving it running.

What's with the Airplane toggle thing? I could have sworn that when I read about the toggle trick, that I only did it once and it worked right away. But the last two times I restarted my phone (once on purpose, and once because the battery totally died), I toggled Airplane mode, but then I checked maybe 20 minutes later and my TWS was around 17%, so I had to toggle it again. But by the time I noticed, I had lost about 15% of my battery life So is twice the magic number? Or is there some sequence or time to leave Airplane mode on before toggling it off again?

do you have the latest update?
something on your phone is not right. you probably have some app sucking up all your cpu or your phone is never sleeping.
i can easily go 12 hours without a charge. and i use my phone all day - listen to last.fm/ browse the internet/ play angry birds/ probably 50 texts total in a day at max/ maybe 10 minutes of phone calls.
but i usually charge it before i have to worry about it getting low.EPIC 4G

I would warn everyone to skip the Startup Auditor Free app. This thing ended up force closing on boot, which boots apparently before the home screen (i hadn't even disabled the drm service in it yet) and i had to hard reset my phone. I'm not an android/computer n00b either. Really an awful app to be recommending anyone install.

I installed Startup Manager and removed the items mentioned from starting up. I have also turned off 4G as I'm not in an area that has coverage, and I turned off Bluetooth. What a difference that made yesterday. I was over 50% even at 10pm. Today I have turned Bluetooth back on but left 4G off, I want to see what happens today.
I also uninstalled Juice Defender and the App Killer that I had installed.
If I can make it to 10pm with even 20% of battery life left I will be well happy

Jason, Battery life was one of my concerns when I decided to purchase the Epic. Thanks for the great info in your blog. It made me realize that the Juice Defender app was hurting battery life by turning off wifi while I was at home when the phone sleeps. I changed the settings on Juice Defender to never turn off wifi while in range, but it disables it if I'm not near a known network. My 3G signal is not very good at home so disabling wifi would certainly cause additional drain.
I work out of the house for several days, and then travel several days at a time. I bought a few spare batteries and chargers to accomodate my travel needs. I start the day with 2 spare charged batteries. I bought the samsung OEM spare battery and charger with stand. I notice that my batteries are 99-100% charged when using the Samsung charger as opposed to 95-97% when using the phone to charge the battery. I have seen a few complaints on batteries not fully charging, so I thought I would offer my observation.
I also bought a pair of "samsung" batteries and another wall charger for just $25. The batteries have a samsung label, but I noticed the name on the label does not include the upside down V for the A in the Samsung name. Even though they are clearly not the OEM batteries, they still provide comparable performance (90% +/-) at a great price. I don't want to appear like a marketer of etailers so I will just say I found them at the large river in s. america.
I'm hoping 2.2 will include some efficiencies that help battery life. Thanks again for the tips.

Getting Started with Android - Tips and Tricks section on Battery Life Tips and Tricks. Getting JuiceDefender properly set up can make a big difference. It is a list of general tips not specific to any one phone. Hopefully they will fix the Epic's DRM and Low Cell Signal bugs. But the advice still stand: CHeck to see what processes, app, and widgets are taking your battery.
Thanks for so many great ideas here and in the old thread.

I just discovered the trick where you can adjust your screen brightness using the top status bar. You just slide your finger across the top (from left to right or vice versa) as if there is an actual slider up there to drag across the screen. I never knew this, and now I dont need to use auto brightness anymore because I was sick of using the homescreen power widget. Android is the shiz lol.
Also, I just swapped to another Epic due to the screen being lose and I think I found the culprit for my battery drain. I had the Touch to Talk app installed on my phone, and that has to constantly run in the background to receive chirps. After going through and installing all my old apps on this new Epic and forgetting to install TiKL, I noticed my battery life went back to the 24-36 hour range again. Here's to hoping that fixed the problem.
BTW.....this keyboard skip is annoying and has been happening on all the Epics I've had. Makes me wish we had a keyboard-less Galaxy S device even more than I originally did when I first saw the Galaxy S devices and the price of the Epic (unless its just a software problem).

I installed the free Juice defender and set data at "always disenabled" and screen at "on at screen unlock" and this works like a champ. As soon as my screen is off 3G turns off. I also bought Power Control Plus which allows you to add as many button/widgets as you want ( I started with 4x1 and added about 7). It has a "2G/3G" button but it doesn't work with the Epic but there are 2 other cell data buttons. The first one DOES turn 3G on or off, so I have 2 ways of turning 3G off. This (turning 3G off at work where I have a very poor signal) has dramatically improved my battery life! Juice Defender has a free but limited version and Power Control Plus is $1.99. I recommend both especially if you are in an area of poor 3G reception, that way you can still receive calls and text but just not data which you can turn back on when you need it. I'm considering now buying the Ultimate Juice Defender for more options ($5.99). Hit thanks if I've helped.

Update: Tried the Ultimate Juice Defender for 1 day and uninstalled it in favor of the free version. I found I liked the Free version coupled with Power Control Plus. I like having more instant control, but the Ultimate did have a lot more options for Auto control.

To avoid overcharging and to troubleshoot battery drain, I've been putting my Epic into airplane mode at night off the charger. It will lose approx. 30% of battery over 6-7 hours! WTF is it doing? Biggest cpu users per Spare Parts are android system and suspend. Contrast that with my off-network Centro which has 60% left after weeks on the shelf. Seems like something fundamentally wrong. Any explanations or suggestions would be great.
