What sucks YOUR battery?

---

I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.

There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.

My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.

What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?

Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).

Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.

And I keep the power to the lowest setting on a daily basis.

The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.

Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.

Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.

my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.

My current numbers:

Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%

Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.

I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.

I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.

I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.

I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.

I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.

Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.
