ok guys as advised by someone i fully drain my vodafone magic till it dies and then charge it to a 100%.
last night i did the same just before goin to sleep,when i woke up in the morning the battery was at 76% after about 8 hours.I just had 1 missed call,1 sms,1 tweet and 1 email.
How can the battery drain so fast for no work at all???
pls help......
Do you have alot of widgets running? What do you have switched on, Bluetooth,GPS,WiFi? How often do you have the "Data Synch" set for? All of these drain the battery, if they are all working at the same time it goes pretty quick.

Woa! For the battery to drain overnight to 76% is crazy. never had this problem with my magic. It actually last very long.
But 76% overnight most likely means your battery is faulty and or you are leaving gps,wifi,and have quite a few things running on the phone like ClintonH stated.
however if you have everything off, as well as the brightness set low. Then contact Vodafone and let them know your issue. they should replace your battery at a free cost.
I suggest people use their battery for a week or 2 to see better results with their battery life. I started having poor battery life with my magic but now I can last about 2 day before I recharge it again.
As other user mentioned, it also depend what you have on or running in the background when your phone is on standby. I suggest you use task manager applications to kill unnecessary applications that might be running.
thanks guys
nope i have gps bluetooth and wifi turned off
i turned the background data off from settings
will try gettin task manager and see if it makes a diff!
thanks once again

Yes, are you by any chance downloading apps? Sometimes they hang and the download stops / continues lots of times. And when they complete your trackball flashes white.
ok thank mate i'll keep note of that!
I read a quite interesting post in the vodafone forum.
A user complained about the battery life of his HTC Magic. Check the answer from Wayne_Vodafone:
The HTC Magic employs a battery that requires overcharging and topup charging. You must charge it as much and as often as possible. The more you charge the better the battery life becomes. So after a few charges you should see the benefit of this. Letting the charge drain out undoes this so try and charge as often as possible

It actually seems to work. At least for me, try it for yourself.
I have to charge my HT-03A every night if I do not want it to die the next day. I am assuming that is why HTC gives you two batteries, because the battery goes so fast. As long as you are able to carry that second battery around with you, and be able to charge it every night, I don't really see a problem. But for it to go from 100% to 76% overnight means you are running programs that you do not need to. I will add that I have Wi-Fi continuously on, and my Contacts and Calendar are continuously synchronized. With barely any use I am usually at around 50% by the end of the day.

Pretty interesting, and that was an official vodafone response? Why wouldn't HTC say that in the first place? Will give it a go anyway...
Yeah, was a official Vodafone Response.
For me: I've loaded mine over night this morning, now its 19:26 and it's still over 85%. I used it for some SMS, receive a MMS and some WLAN.
ok guys thank u so much for the responses,im gonna give it a go too!
im using taskiller and defi my battery life has improved cause i keep killin the apps im not using
about the flashing trackball.......it still happens...no notifications.....
You never want to drain a Lithium-Ion battery. NiCd batteries have memory, in which it's better to drain them. But not Li-Ion. They will die quicker if you do
ok thanks xantonin.....
i charged my phone to 100%,then made a call for 41 min,battery went to 91%.
went to sleep immediately after that,woke up in morning with 1 missed call and 1 sms,after 8 hours......battery at 70%......thats not right is it?

That could be right.
Depends on what's running.
Where are you checking for 100%?
If you are charging until the green light comes on - that's 90%. The phone takes longer to charge passed 90% than it does to charge up to 90%.
I charged to 99%, and drove around with the GPS on for a few hours (about 2) and came back at about 75%.
However some days, when I charge my phone over night (true 100%), I can listen to music on my way to work (40 mins) on my phone, play with it a bit at work, and 3 hours later it will say 94%.
So, the battery is very touchy it seems...
Try turning off 3G (It's still pretty fast on 2G, try it for a day)
And also make sure GPS is off. Keep your brightness no more than 30%, and make sure WiFi is off. Make sure you don't have any widgets that connect online either.
You should get good standby time
Use apndroid to save battery life
Download apndroid from the Market. Use it to turn off the cellular internet before you go to bed and whenever else you want to save battery life.
There's also an app called Spare Parts in the Market that could help you. As well as giving information about your battery status and battery health, you can also see stastics of your application usage and battery history. A very useful app!
Plus it also enables other features like enabling fancy animations for the keyboard and screen rotation.

If you longpress the red phone button you can also enable "airplane mode" disabling any radio. Which helps your battery life too.

I left my nexus one, which I just got on Friday, next to the TV and it was fully charged. When I came back to it about 4 hours later it had turned its self off and wouldn't turn on until I connected the charger. The battery was at 0%, anyone seen anything similar?
I have now left the phone off, connected to an AC charger and will turn it back on only when it's fully charged!
Sounds like you got yourself a defective unit.
Charger it fully then let it completely die. After it dies charge it again fully see if that helps.
Charging via the USB cable does not seem to be very efficient/reliable. Using the AC charger is quite fast, and much more reliable.
Also check the apps that are running in the background, and turn off the ones you don't need. I discovered that the animated wallpaper was quite a drain... since I switched to a static wallpaper image, battery life has improved significantly.
It has the star field wall paper, but I didn't think that would run when the phone is locked and the screen was blanked. I'll leave it to fully charge, using an old nokia charger from a n85.
So the recommendation is to run it tomorrow until it dies then charge in the off state and only turn on when it's fully charged?
I have had a G1 for the last year.

I have the same problem. I got the phone approx. 1 week ago. before i go to work, I would have a fully charged phone. during lunch break break, ( about 4 hrs later from fully charged) its below half already! then 2 hrs later, its at to the point where it says connect your charger. Finally, off work, Phone is turned off and dead at 0% battery life. When im working, i dont even use the phone to browse or anything. just check the time on it and put it back on standby. I dont know whats wrong. Ive also rooted the phone btw with MoDaCo's rom. Any suggestions?
It was fulling charged again about 3 hours ago, not I've left it without wi-fi and with a static wallpaper and the battery is still full. I wonder if the wi-fi or the live wallpapers keep running even when the screen is off. I have checked and wi-fi is set to sleep when screen is off :-/
While modern batteries don't have the "memory" problems that cause them to lose life, they can suffer from miscalibration which will cause them to inaccurately report their remaining charge. If they report a very low charge to the phone (when this may not necessarily be true) the phone will probably turn itself off.
To recalibrate your battery, force it to drain completely. Even after the phone turns itself off, turn it on a few times more. I can't guarantee this is good for your phone, but it should get the last of the juice out. Then, when you let it charge, let it charge LONG after it reports being full, at least a few hours, to make sure it's completely full.
Sounds like something isn't quite right with your phone tbh. I have the star field wallpaper, wifi on and it's checking e-mails for 2 accounts every 15 mins.
I've also had some phone calls, been surfing the web, market and generally played around with it since I just got it on friday.
I checked the battery info on the phone now and it's been 15 hours since I charged it and it's now on 46% still. In my (limited) experience the battery seems to hold up pretty good on this phone.
That's the weird thing, it was fine Friday night and Saturday night and that was including quite a bit of playing with around
I received my phone last week. the battery was fine the first four days. after that the same problem stated above happened to me. the battery dies every 4 or 5 hours even in standby with no GPRS, WIFI or BT.
I did a complete wipe-out and the problem was gone.
I think that there were something that is draining the battery and gone with the wipeout.
by the way, i was using MCR and still using it.
thanks.
It has now been sitting for another 7 hours without wi-fi or starfield and the battery is still showing full. I'll now enable wi-fi and see how that goes. Then I'll try statfield later on. I'm wondering if the starfield keeps running even if the screen is blanked.
Actually it's showing 92% in the About page whereas the icon look full :-/
First day with nexus at work. Unplugged it from the main charge at 6:30 am at till 1:00 pm its was turned off. Made 3 short calls, no wifi, bluetooth, or gps and screen set to auto dim.
Only 6 1/2 hours is not long enough. I wish there was like a juice pack for nexus like the iphone. I could buy another battery but cannot be bothered carrying too many bits with me and opening it and changing.
Aslo charging through usb is very very slow.
my phone did this yesterday too, first time ever. I dunno why it drained so fast, something must have kept the screen on in my pocket or something.
Here's what I found.
I got my phone friday, took it off the charger and went to bed. When I woke it up was dead. What I do know is that since I'm with Roger's in Canada I don't get the 3G. I think it was searching for a 3G signal all night and that's what killed it. Try limiting it to 2G and see how the battery stands. I went a full two days without a charge, playing with it every chance I got and wifi turned on.
I'll try the 3g thing as the phone reception is poor in the room I left it. It is at 79% with the star fields wallpaper and wi-fi enabled (sleeps when screen off)

The star field wallpaper KILLS my battery even when the phone is idle with the screen off, just FYI... I switched to a default regular wallpaper and it has been fine since.

thanks i will try 2g setting tomorrow.
There gotta be something wrong with your phones or some software that is draining it.
Like I said on the previous page I use:
WiFi on
Star Field live wallpaper, with the background image nontheless
Some GPS use
Several phone calls
Some texting
Browsing the web
Screen brightness at maximum
2 email accounts updating every 15 mins
My battery still lives through the day with ease and I'm usually at 40% when I go to bed at around 1 am. I would call HTC or do a thorough check at what software is running.
edit:
Oh and I have 3G on with low reception (1 bar) where I live.
Ok, guys look... I know there are lots of variables, but I get back from work, it's been 12 hours since my 100% charge, I'm at 26%. I get home, I charge my phone. It's back up to 100% in about 2 hours. I try some weather widgets on my phone, answer 3 emails quickly, I'm down to 83%. Something must be up, right?
I have notice this happen and its because the phone reads the battery is at 100 but you still need to let it charge longer for it to hold the charge. I suggest a full charge then kill it until it shuts off. Then let it charge while off until the LED turns green and maybe for a little time after that. Do that a few times and you should see some improvement.
Ok, well perhaps I'll have to try that then. Can the battery be reconditioned? Do these batteries have memory?
How long have you had the phone? Battery life should improve after having the phone for 5-10 days.
Like what joe333x stated.When I first got my phone I charged it up to 100% and turned it off until the led turned green for about 30mins. After that I get about 16hrs of battery life.

I've had the phone since last Thursday night (not yesterday) and I know that two times, I unplugged when it was orange. Guess I should have left it.
The other thing possibly battery related is that right now for example, I have thhe little cycling arrows icon on my taskbar. I am 99% positive that I have nothing set up to be syncing for THIS long. It's been on all day. I unplugged at 7:45AM, it's now 11:21AM, I've done maybe 15 text messages, and the phone is at 77%. You can see how I might find this frustrating.

i understand. i'm having the same problem. my battery died on me after 5hrs of usage, or complete setup, i should say. i just got off the phone w/ t-mo support in hopes of getting a replacement battery. no go. the operator said her phone dies in 2-3hrs, so i should be happy w/ 5. opted me to buy a spare battery for $50. i am very displeased.
you guys have something running in the background for sure ..go into your acocunts and sync the very least turn off the tmo garbage if not all of them except for google.. If you see my thread I've gone over36 hours on one charge
I've got all of them off, even weather cause I'm using Weatherbug.
But I do have background data on. But I don't wanna be completely disconnected to my data. What exactly does background data run?

my 5hr kill is after doing a factory reset. only thing set to sync is google. no facebook or twitter accounts are linked. display is on the minimum. screen timeout is 15sec. no wifi, bluetooth, or gps. so i'm at a lost.
are you still experiencing that kind of life?
Same here. No wifi, no bluetooth, no Google, no GPS. All I have even remotely "automated" are my emails, my text message data, my freakin phone. That's it. It's gotta be the battery charging thing I think because there's nothing else draining my battery and yet the little sync circular arrows are still on my task bar.
Oh, and by the way... since my message at around 11:15 or so, I'm now down from 77 to 70 per cent. 7 percent in an hour without doing anything.
The things like tmobile and weather are set to sync automatically from the factory (meaning theyre set after a wipe) Have you guys gone into the settings and made sure you turned them off??
I have, yes. They have been off all week. 12 hours usually gets me down to about 26 per cent. That's a 6 day average, moderate use.
that doesnt sound too bad for 12 hours.. have you tried killing it a few times and fully recharging?
my thing is, i find it quite unpleasant that i'm having to disable all the basic or advertised functions of my phone just to have the same, if not, worse battery life? i find myself not even wanting to answer some calls because of the thought that one 5min conversation will dock my battery more than 5%.
It is incredibly ridiculous to have to be constantly concerned that if I do a search on the internet, that my phone may die earlier than I can afford. Additionally, I don't wanna be one of those annoying people running around all over the place with an AC adapter trying to plug my phone in every place I go to. Nor do I think I should have to keep a USB cable handy for when I'm at work. Plus, what's the deal with the batteries, do they or do they not have a memory that requires them to be fully charged and then fully discharged?
Hey guys,
I just joined because of this specific issue myself. My girl has the mytouch 3G and she could go for almost TWO DAYS without a charge. I leave my house at 7AM every morning, and return about 7PM. By the time I get home, I've maybe texted a few people, made one or two phone calls, and my battery is sub 30%. I've turned off wifi, bluetooth, and the display is just about as dark as it can go.
I just turned off the background data option, and had to manually go into all the accounts and make sure the sync was also not running. We'll see what happens.
Does anyone know if there is a 2.2 FW for this phone we can use yet? I've read up on user created FW (like cyanogen) because they cut out all the useless crap most of us will never use.

I noticed this too. Its due to that fact that from default there are a bunch of things that sync now not just your gmail account. Go into settings and disable all the unneeded things and you wont see it as much.

I have had these issues before and it was almost always due to somthing in the background.
but letting the battery drain till it shuts down then charge 5+ hours then drain again, always going till it dies is the key, it will run a long time after it says it is done...

i'm continuing that "conditioning" now. it died yesterday after 5hrs fresh from a factory reset. i charged it for 8hrs. i will perform another day of drainage and overcharge today.
I turn my phone off last night with 50% battery left. This morning I turn the phone on and it tells me to charge the battery and then shuts off.
Here is where it gets weird; the exact same thing happened to my wife's phone except she had almost a full charge before turning it off.
What is going on?
I don't know I have gone 26 hours in mostly standby and I still have about 65-70 % of battery left. Check all your settings. I only have sync and back light to Auto turned on.
This is not normal and has never happened to me. Have you installed any apps from the market?
Little more info, please. Are your phones pre-OTA or have they been updated? Are they rooted? Did you just buy the phones? Have you trained the battery (fully charged then fully drained)? Have you done a factory reset?
Both phones are post update. Both were turned off by holding the power button then selecting "power off". Both have exactly the same apps that we had on our previous Androids (Vibrant and N1). Both bone stock. Have not factory reset, really don't want to go through the work of setup again.
I have never powered mine down completely overnight so I guess mine is not the same comparison. I might try it though just to see.
Ya they hold a great charge all day when on nut lost all their charge when powered off.

Is this a feature known to eat up battery? I mean if I left the phone on all night it would have still had a charge.

Idk, shooting in the dark here, never heard of a problem like what you have. Wouldn't hurt to try. I know the fastboot has something to do with the way the phone shuts down.
That battery behavior is just strange unless you have apps syncing frequently.
I unplugged last night at 1am, went to bed, and got up this morning at 8am, it went from down fully charged to 93%. I have autobrightness on, wifi on, gmail and exchange syncing, every other app that syncs I have it to sync at least every 6 hrs or once a day.
I've had this phone for 3 days now, and I'm consistently able to get 12-14 hrs of battery time, and that includes heavy internet use, radio, tv, etc.
Are you in an area where it's constantly trying to pull a signal? Maybe that's what's eating the battery?
Are you doing the steps to condition the battery? Charge until fully charged, turn it off and keep it charged another hour, then take it off charge and use it until it completely dies on its own, charge it back up again and then use as normal?
Yeah, but he saying he powered the phone down, not left it on and just idle. Now that's strange

Yes but he is powering completely down not just in standby mode so nothing would be syncing. I will try this tonight and see if I have the same thing.
My wife had about 75% charge, I had about 50% charge. We both held the power button until the menu came up, we hit "power off". Both of our phones had dead batteries this morning.

None of this would matter cause the phones are powered off.
If you have fastboot checked, the phone is not actually turning off. It goes into a quasi-sleep state and some low level processes may be running. That said, your problem may be related to the following thread:
forum.xda-developers.com/showthread.php?t=839935
the fix: enable USB debugging mode.
Another possibility, and this is someting that's happened to me in the past: the phones may be plugged into an outlet that loses power when you turn off the lights at night
Fast boot is similar to a Windows computer going into hibernation or standby mode.
Mine has been acting weird since Friday. I woke up and it totally discharged overnight... it was 100% charged when I went to bed. Yesterday it was laggy constantly and the battery has been draining at least twice as fast. Today phone locks up constantly.. apps are force closing.
... have rebooted, pulled the battery, etc... phone has gone from a dream to a nightmare in that respect.
Gonna double check my debug settings and see what happens.
EDIT: debug was turned off. I turned it on... will report back if there is a change.
UPDATE: Turning on USB debugging and a reboot seems to have fixed it. Battery drain `back to normal.
I am LUCKY to get 8 hours of battery life on my brand new stock Epic.. I usually get 4-6 hours. It will NOT last through a normal day of work without putting it on the charger around lunchtime. I take it off the charger around 6:30 AM and I am usually home by 4PM and have to immediately go and charge my phone.
Even if I put it on airplane mode, kill all running applications, and shut the screen off to standby, the phone still seems to suck battery life down very quickly (~5% in 20 minutes on airplane mode, wtf???).. So airplane mode doesn't help.. And I really DON'T want to put it in airplane mode to conserve battery because then my phone is completely useless -- it won't even ring when my wife calls..
Is my battery defective? Please tell me it is... This can't be right..
Are there processes still running that use lots of CPU, even when the stock sprint "task manager" program shows that nothing is running? Is there anything I can do to improve this if I root the phone? How about custom roms? I would really like to run Froyo/Gingerbread anyway.. If anyone has any suggestions to help to make my battery life not such an EPIC FAIL, I would greatly appreciate it.
EDIT: Also wanted to comment on the SLOW CHARGING. With the stock Samsung wall charger, it takes at least a couple of hours to get a full charge. With a USB cable plugged into a PC overnight, it only gets to about 50%. Compared with my previous phone, the HTC TP2, this is really really REALLY slow. It charged in 30-60 minutes and the battery lasted much longer.
I did notice that Samsung only provides a 0.7 amp charger, versus a 1.0A charger for the TP2. Why does Samsung limit the charge current like this? And apparently there is no nueBattery mod driver for android
UPDATE: JuiceDefender looks very promising. Installed the free version and my battery is only down to 95% after one hour. Thanks for the suggestion.
FWIW, I'm getting about the same 8ish hours on mine running DK28. I'm losing about 4% an hour without touching it. I'm seeing some people claiming insane battery life (18 hours with heavy browsing on wifi) I wish I knew how they were managing that.
Wait, it won't even ring when you're wife calls? and you're complaining?
First, the airplane mode means you switch the phone to airplane mode first then switch it back so you won't have time without signal problem which can cause battery drain.
I am able to get 10+ hrs at least by doing the following
1) use airplane mode trick so no TWS
2) use titanium backup to remove a bunch of stock junk
3) use titanium to freeze certain applications (DRM, MediaHub, Qik etc)
4) Have as few applications as possible that constantly pull data
Just yesterday I had 1 day 17 hours before switching
Yesterday when it finally gave up the ghost with the battery indicator blinking i checked my stats.
I had 1 day, 17 hours unplugged. Screen time was around 2 hours and some minutes. I had 45 minutes of talk time.
One thing i will add is I purchased a charger with two batteries off Ebay. Previously when charging with the stock charger as soon as I pulled it off the charger it would read 97%. With the seperate charger it reads 100% for quite awhile before it starts to drop.
And for the record I purchased this charger and two batteries of Ebay for a winning bid of $0.01, plus $9.95 S&H. It was a steal in my opinion.
Unless you are getting near 12 hours of battery life, one of 3 things is occurring:
1) You are using the phone an insane amount
2) You messed something up
3) The battery is defective
For the record, its almost always number 2.
I suggest doing a Factory reset, which will wipe everything off the phone. Then without installing anything or setting your facebook to update every 15 seconds, see how long the battery life lasts. If it is still only 4-6 hours, then your battery is most likely defective.
well of course it won't ring if your wife calls if its in airplane mode. That radio is turned off.
8 hours? That's it? I wouldn't call that normal, but that's just me...
I just plugged my phone in after 4 1/2 days (108 hours) running on a stock 1500maH battery, running Quantum Rom 1.5 (DK17), no special apps running to disable data (aka Juice Defender, etc.), not in airplane mode at all, with the DRM software running, in other words, a more or less 'Stock' configuration (taking into account any differences in the base Rom).
Granted, I barely used the phone in the last 4 days though

I'll do that. For the record, I've got fbook set to never update, and seesmic once every 6 hrs.

LOL at screen on for 52 minutes total. That is 11.5 minutes a day.

Like I said, barely touched my phone in the last 4 days... been feeling a little under the weather so have been at home a lot and in bed doing all my internet stuff and gaming (pogo) on a laptop instead of on my phone.
Since I updated to the leaked Froyo, my battery life has plummeted. It lasts maybe 1/3-1/2 as long as it used to. Turning off 3G has helped immensely though, so that must be the culprit. I used to be able to leave 3G on while at work and make it to bedtime before having to charge it. Or if I shut it off at night (which I usually do), it would make it through my commute to work the next morning. Now, I'm lucky to get through the work day unless I turn off 3G. Huge difference in battery life for me since updating. I'm hoping they fix this in the official release of Froyo.
Well, I've recently found out that if you flash via update.zip while the USB is plugged in, you'll mess up the battery calibration of your device. This is what I did, and i'm pretty sure the cause of my problems. I did find a fix, and here it is:

This is the procedure that works for me:
The following steps should significantly extend the battery life on your phone:
1. Let the battery drain close to empty (5% or less).
2. Connect the phone to the charger (AC or USB, USB is better) while powered on and allow the phone to charge until the notification LED is green, indicating the device is fully charged and untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better. Use a tool like Overcharged or Battery Indicator to monitor this. Note that a green notification LED does not automatically mean that the voltage is good too.
A higher voltage means in practice that it will take longer to discharge, a lower voltage means that the battery will discharge a lot quicker! The difference can be quite significant!
3. Disconnect the phone from the charger and power it off.
4. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
5. Disconnect the phone from the charger and power it on.
6. Once the phone is powered on completely (has restarted fully) wait 2 minutes and power it off again.
7. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
8. Leave the phone on the charger and reboot into the ClockWorkMod recovery menu and wipe the battery stats via -> Advanced -> Wipe battery stats.
9. Disconnect the phone from the charger, restart the phone and start using it as normal.
From then on always let the battery drain close to empty (5% or less) as often as possible and then charge untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better.
Normally you will have to do this only once. However, on all Android ROMs, if you flash a ROM while charging or during the first boot screen on, first boot mucks up the levels Android thinks the phone is at, i.e. Android will think you’re at 100% when maybe you’re only 90% or whatever. So in theory you will need to repeat this every time you flash a ROM while charging!
Better is to make sure the battery is charged before you flash a ROM and just remove the USB/charge cable before you flash a ROM. Put it back in (if you must) after the first boot screen (when the custom screen or whatever shows).

There is a shorter version that also seems to work well:

So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.
Battery should now be calibrated.

From what I've been told, you don't have to wipe the stats (you need root to do that) but it helps if you can.
I think this may also stem from interrupting the inital charge of the device. I know I did this on both my wife's device and mine (plus my added fubar of flashing with the USB in). Anyway, hopefully I can report some good news tomorrow.

I get 4 or 5 hours if that. I can barely make it to 6. But i probably use my phone more than the average person. Because i take public transportation and browse, stream, email and have 4g connected on my commute back and fourth.

I've been running JuiceDefender for about 5 hours now and I am loving it.. I still have 75% and I can still receive calls just fine.. It turns off data when the screen is off, but turns it on at scheduled times (default is 1 min every 15 min) so that your emails/twitters/etc can update like normal. The paid version has even more features so I bought it..
Never mind im dumb for not reading his post. Already answered my question sorry.

Decided not to quote the whole thing but I'm in the process of doing this right now! Took 2 hours to drain my batt from full (running everything and keeping my phone searching for gps constantly in a place where it would also be searching for signal makes quick work of a battery!).

I definitely need to try that out. Can you still receive calls or no?

Yes, with juice defender I can receive calls and my gmail/twitter/facebook/etc. are all already up-to-date whenever I pick up my phone. It works exactly as before, except my battery is not constantly being drained now.
I guess the downsides are that I might not get a new email notification for 15 minutes, and that there is a service running in the background that may cause some slowdown. Neither has been a problem for me so far. I highly recommend this application for Epic 4G owners. Problem solved, basically.
I usually get 12hrs with moderate use (~2hrs with screen on, half of that is usually on the browser). I turn background data off bc I don't have a twitter and I rarely check Facebook so when I do I just use the browser.
I also noticed that wifi burns more battery on DK28, on 2.1 I would hardly lose any battery on standby with wifi, now I get a 3-4% drain per hour... But with 3g on now I lose less then 1% an hour, it used to be a battery hog.
