The only thing I care about is the battery life... Is it better than the Evo?

Yes it is a lot better than the evo due to the screen for one because the evo screen is a tft which used more power than the sport amoled does so that's a big plus

Agreed, the battery life will be much better than the EVO. But what people dont realize is that they can fix the battery problem with the EVO if they know how to use it right. Like disabling google talk (noone uses this, and if they do they're stupid =p ) .. also simple apps shuch as task killer and droidbattery help TEMENDOUSLY. On another note, the EPIC is going to be amazing. I can't wait!!!

i have an epic and the my battery drains in about 9 hours...........idk if thats better than the evo but its making me angry. overall the epic is amazing but the battery life brings down what would have been a 5 star rating to a 3.

the battery life of both of these phones is not good at all....max. 6-7 hrs....very frustrating..and if you actually are using the phone, playing games or using any other app. then its not even 4 hrs.

The Last two are incorrect. The battery life on this phone is amazing. Stock out of the box it is just ok like they say. There are simple things that can be done that will dramatically increase battery life. I used to be upset about battery life but after the last update and doing the tips that they suggested on android epic 4g forums I can go for more than a day without plugging in and I am a monster user (games internet the whole nine). I am not an epic or android fanboy either. It is an excellent phone just needs to get 2.2 so that I can look at flash websites. Flash Lite is garbage and only good for ads truthfully.

I got on my epic this morning at 7. Made some calls, txted a few people, read some news sites like cnn.com, played a few rounds of angry birds and my battery is dead. Its noon. I used advanced task killer throughout the morning. But this battery still sux.

Use advanced task killer. Set to aggressive and to auto kill every 1 hour. Keep your GPS, and WIFI off unless using it and your brightness to zero.

Make calls, surf the web, play games....over 24 hours of life.

im not getting the epic till friday but i already have an android phone already and it didnt last me my school day, but i looked up some suggestions on how to keep life a little longer. you can turn your screen down all the way [on my phone it doesnt look different to me]. and turn gps off. also an app called CacheMate theres a free version and one to buy, you can get it for free with an app called 4shred though:)

Some tips:
1) Go to Settings > Applications > Running Services > Disable the DRM and Media Hub related services.
2) Set screen to lowest resolution
3) Use Touch Wiz Running Programs Widget and make sure no actively running applications are running in the background
4) Get advanced task killer, turn on and kill selected tasks making sure that everything is check-boxed including task killer itself.
5) When Wireless networks are available make sure you use them and use the following setting: Settings > Wireless & networks > Wi-Fi Settings > Hit Menu Key and > Advanced > Wi-Fi sleep policy > Select option "Never". This will prevent your phone from shutting off the wifi connection while asleep, this will save battery for two reasons: First Wifi takes less battery than 3G, second because it will not need to restart the wifi service and re-establish the connection every time you turn the screen on.

You should get no less than 12 hours of mixed use out of this bad boy.

android has a built in task killer already, 3rd party apps that are task killers ruin the functionality of the devices. They are a good idea in theory, and theory only.
Androids will close down tasks as they arent being used. Not always instantly, but 3rd party apps will kill android processes that are crutial to the functionality of the phone

The 1st day I used my epic, the battery was gone after 8 hours. I've gone thru all the steps to extend battery life and it does work. I use the samsung widget program monitor to kill all apps when I am done with them. I set wifi to always on. BTW it was hard to find till I read the steps and use the hidden advanced mode key.I also use the android widget called power control. Also have brightness set to auto. I am very satisfied with this phone now. They should give you a stronger battery with purchase or tell you how to conserve the battery in the owners manual.

I know this thread may be a bit stale, but I got some good comparisons
done with a friend's Captivate and another friend's Epic.
BLUF: Chinese made batteries suck horribly.
Pretty much, they all had the same optimizations done and we were all pretty much doing the same battery-sucking stuff (I.e. playing Angry Birds Seasons). My Epic and the Captivate lasted a little over an hour. The other Epic had 65% battery. My friend with the Captivate bought two spare batteries, both Samsung 1500mAH, and one was Korean manufacture and one was Japanese. Swapped out the cheap, POS chinese cells, and an hour of Angry Birds later, we were still over 70%. Cracked the other Epic open and found out that our two Epics, bought on the same day at the same store, had Samsung batteries made in two different countries... his was Korean, I got screwed with Red Chinese garbage.

DONT DOWNLOAD THE ANDROID ADVANCED TASK KILLER! it opens up applications and has them running in the background. Its better to use the task manager that comes with the phone.

i demand somebody show me a smart phone that lasts days on a single charge like all of you seem to expect. get over it...phone technology is advancing while battery tech remains the same. That said, I've experienced nothing like all of you are saying, and I love playing with this new toy of a phone. I unplugged it before I went to sleep last night around 2am, and i didn't plug it in again until about 10pm tonight, at which point i had a 19% charge. Granted I tend to use the phone a little heavier during the week when I have school, but this is still waaaay better than with the palm pre that I just ditched. That stupid pre had me lugging around not only a car charger but even an extra WALL CHARGER for when I went places. This thing is easily going to get me through an 8 hour school day...and if it doesn't, i'm not going to complain...i'm gonna just buy an extended life battery.

I like your article that guides me to increase the battery life of laptop. Mobile computing has got better with lighter components, better chips and faster processor. To get rid of this we should, we have to follow these point that are Reduce your monitor brightness, Do one thing at a time, Shut down services you don't need and Keep it cool. Thanks a lot .
