battery issue - Focus General

Last night I left my phone charging over night. This morning once I took ot off the charger the battery was reading one percent. I went ahead and put it on the charger thinking the mini USB cable connected to the charger (att OEM charger) might have slipped off. Well after charging it from my car for another 30 minutes it was still reading one percent battery. I went ahead and reset my phone and voila it registered as fully charged. The weird thing is that while it was in critical battery mode the phone was performing very slow. Just wondering if anyone ejse has experienced that.

Battery issue?
I had the same problem when I checked my phone this morning. I had it on the USB cable almost all day yesterday and I showed a full battery when I when I went to bed. This morning I had 1% battery. I am charging now on the USB cable again and it does seem to be charging so we'll see.

I don't know how windows manages their memory on this os. I know they said they wouldn't have multi tasking but thus far I have realized that they do allow some apps to run in the background. I know in previous windows os the biggest issue was apps staying on in the background and eating up memory . So I hope the battery issue and the lagging isn't a direct result from that .

The battery on my phone charges but seems very slow.

Well, i have GPS turned off, wifi off and it takes about 2 hours to charge with the screen being off. i get about 3+ days of normal use from a fully charged battery. Maybe you have many things turned on and as such the phone us using power to feed those and less to feed the battery?

yesterday I got a good 20 hrs or so with heavy data and push emails.. today I barely got 12hrs.. the only difference today for me was that location services was on.. So I think the battery drain comes from GPS mostly and definitely wifi if you keep it on

Yes, GPS and wifi can really be drains, bluetooth not so much it seems. As many of you know, if you are charging your phone using your computer's USB port it may be far s-l-o-w-e-r than using the faster AC adapter.

Ok and thanks for the tips. I have been using the wall charger. I will turn off location and see how that goes. Most of the time I don't need it anyway. I know where stuff is where I live. HAHAHA.

I've had my Focus for three days now and the battery never lasts more than 12 hours - and I haven't made any calls with it! I have it for testing, so it's not my main mobile but I've been using it for everything else. Internet, email sync, Zune, social networking, etc.
I turned off wifi, location, bluetooth, set the screen to low brightness and still only ~12 hours.

Another critical bug on the universal :-(

I just found another painful bug....this one is related to charging (battery). I normally put my qtek on charge all through the night when I go to bed. For the last 4-5 days I have been unplugging the device when it showed 100% charge, put it on standby (no wifi,btooth,gsm etc.) and made sure there were no applications running. I usually leave it in the standby state for 2 hours while I finish my morning exercise.
whenever I return, I see a power loss of 20%!! I was shocked to see how I could loose 20% in 2 hours ith my device on standby mode. this time, I even made sure I pressed the power button before I closed the lid, and still...no luck :-( I still lost 19%
I guess the problem is, when the charger is connected and the battery gets completely charged, it stops charging further. I guess it reaches a fully charged state within 2 hours, and the battery starts to drain all through the night...and wm5/htc don't start charging once again when the levels go down....i'll have to do a cuple more tests until I can totally confirm that this is the bug...until then, are anyone of you guys experiencing the same problems?
Another thing I forgot to mention, once again I charge my battery from 80% to 100%, and it lasts through the entire day(12 hrs) and drops to only 40% with highhh usage (bluetooth ON throughout, gsm on with 3hrs talktime, and some light gprs usage). so it really is not a problem of my battery as I see it!
Cheers,
San
Hmmm. I hate to say, but I don't see that problem. But I do have the unlocked JasJar Universal from HTC, not the qtek. If this happens with other qtecs, maybe they load a custom software that is acting up. In fact, I could leave the device on for two straight hours off a 100% charge and I don't think I'd lose 20% unless the phone was on too.

have you tried charging your device for well over two hours before unplugging? (around 8-9 hours of charging for instance?)
I don't really think it has anything to do with the qtek rom/device. the qtek rom has the least ammt of customisations on it...
I still suspect that the charging process halts and it starts to drain the battery....but the os doesn't reinitiate the charging process once again....hmm
I'll have to wait till tomm before I can do another round of checking....tomm, I want to charge it....and before I unplug, I'd remove the battery and put it back and see what it indicates...I suspect that the power would have already dropped to ~80% by then...that's the only explanation I can think of at the moment....

Hi Dreamtheater!!!
I exactly follow you as far as charging is concerned and I hv a Jasjar....just to inform you...I started charging yesterday at 11.30 PM and just got up to see the charge..it is 100%...no power loss...

it shows 100% for me too...but in just 2 hrs, it drops to 80% which is weird! from then on, it drains normally...
I still need some time to nail the exact cause for the problem...hmm!

Hey dreamtheater, I charge my Exec overnite everynite just like you. Usually at least 7 to 8 hrs everynite, but I have yet to experience what you mentioned here. My Exec always start fresh from 100% and by the time I get home at nite, it will drop to about 70% so no, I'm not getting the batt drain issue like you do..
I did not experience any such behaviour with my Qtek. It charged fine over night and had 100% battery when unpluged.
Are you sure your's does not wake up for some reason after you suspend it?
Dreamtheatre, I charged my XDA Exec overnight (7 hrs) and after 2 hrs with GSM/UMTS radio on the unit lost 5% battery charge.
@DT,
You need to set the device to switch off after a specified time interval. This can be done by going to start>settings>battery>advanced and check the device timeout box. I usually set it to 1 minute.
Last night i was browsing on my JJ and fell asleep while doing so, IE and notes and inbox applications were still open. When i started, the battery level was 93%, i browsed for about 10 minutes over Wifi before i fell asleep. The device shut itself off and when i woke up the battery level was 82% which is prportionate to my 10 min WiFi use and probably 1 minute standby time before it shut itself off.
Try it out, i'm sure you will stop seeing the massive battery drain
Cheers.
Another thing. Contraty to what people think, keeping the universal's battery topped off improves battery life. Prevent it from dropping all the way to say 30% or so. You will notice the difference in battery life in just about a week or so
Another source of battery drainage i've found is when i'm charging my Exec from the USB connection on my PC - If I leave my Exec connected and put my PC into standby, it will literally suck the life out of the battery over the course of a few hours!
I think some of you have got me wrong...let me restate the problem...
I charge all night
Wake up with 100% charge
Pull off the charger
Leave it on standby for ~2 hrs (no apps running, gsm, wifi, all off)
Come back, and find a ~20% drop
Back to my findings now.......
Another morning, no luck :-(
It had 100% charge...I pulled off the battery, put it back in and restarted....still showed 100%, so I guess it really was fully charged after all. This time I turned off receive incoming beams as well....left it for a couple hours, and was disappointed to see 82% when I got back :-(
However, through the day I get excellent battery life....all day's use ends up consuming roughly 30-40% charge which is excellent compared to my prev xda2 which would comparitively loose all of it by eod. I guess if I park my device in flight mode it tends to start draining quickly....now that's my only available reason or cause that I can think of....
tomm I guess I won't put the device on flight mode and leave it just On instead. This is weird because its just me having this problem :-(
San
PS: I'm using the regular ac charger itself for charging...hmm
DT, I disabled PowerSave and switched off the GSM/UMTS radio on my Exec. After about 8 hours I had lost about 30% charge. So your 20% does seem high. It could just be the battery as loss of charge is not linear. Why not let it drop to say 60% and then do your test again. By the way there spare batteries seem to be available now for the Universal.

wizard draining battery !

Dear All,
I have a strange problem here.
I just purchased a used wizard and installed a new t-mobile rom, but, once I connect the charger or the usb, the orange charging light starts blinking!
The battery doesn't charge, but drains very fast.
I re-installed another rom, but it's the same, and I installed another, but also the same.
I checked the battery on another phone, but nothing was wrong with it, then I installed the battery of the other phone on my wizard, and it did the same problem!
I checked another charger, but it's the same thing!
The phone is fully functional, and works 100% other than when charging it!
Any suggestions???
Same problem here. The battery drains almost emidiatly when I charged it. After a couple of time it wont even charges anymore. Tried 3 batteries. All batteries seems to have died. Horrible.
Please... anyone recognize this problem?????
To add: I put in a brand new OEM battey from Sanyo. Charged it with the wallcharger. Then when I put on the device it drains almost imediatly. A brand new battery !! Then tried to recharge the batery and then the phone shows a red led light? What is going on!.
OH, AND NOT FORGET i DID install a new ROm from Moski but the same problem. So, replaced the ROM and battery. Is the wallcharger defect or my QTEK 9100??

Sounds like a defective wizard to me. Might be time to return it and get a replacement.
If you have already purchased new OEM batteries, and you're still having this problem, one would have to assume that it's the charger you're using. A buddy that works with me bought a mini USB wall charger for his Cingular 8125, and on the 1st charge, it completley drained his battery, and it was unable to charge again. $50 bucks later for a new OEM battery and charger, and never had this problem again.
Thanks for the responces. I ordered an aftermarket charger and hope that that solves the problem. I recently bought it for about 210 euro 2ndhand. Sometimes it does startup and looks ok but then in less then a minute the power dies. I will look after the 5 volts and 1 amp. on the new charger by the way.
Once again, if someone recognice this problem I really are interested in the solution if found.
Offourse I will let now if I found out. I'm praying that the wallcharger is the problem.
i had that problem when i was using the razr charger with my 8125. i thought it was the same because they are both mini usb. WRONG!
i hope this is not what you are doing. is your charging cable oem?
Hi. Got a replacement wallcharger and when i plug it it in the led on my Wizard turns RED emediatly. Charger has the same spec. as the OEM. So. Still a dead wizard. Anyone any thoughts?
By the way. I cant even find out what the red light on my wizard means. Should be orange when charging. Red doesnt looks good.
same problem
I'm having almost the same problem
The red light
My wizard won't start, and by the way, I was charging it with a motorola charger cause I only had the car charger , and the cable is 2 short. I actually charge it several times... a month and some, no problems, till now I posted a new thread,
I don't know what to do ... Can it be the main battery ... mabe my charger depleted it I had resco tools installed an it said that my main battery is at 100% ...
Now when I plug it in the car charger, it does nothing..., and when I plug it in the moto charger it shows a red light.
If someone finds anything, please reply.
I found a thread...
Plug in your pda without your battery inside. It shows the red light. Insert your battery, and the led will turn off. Press the power off button, and, voila....it starts. By the way, after it was brought back to life, I quickly pluged into the usb...and the led turned orange. My battery was 0%
Hope this helps. By the way, it's not necessary to work from the first time. Worse possible scenario, let your pda to "rest" without the battery insite for an hour and then try again. I heard it has something to do with heat...I mean, if it's cold, there are less chances... don't laugh It may be true. For me it worked the first time. Good luck.
I was having the same problem. It was fine for a week using this other USB charger then yesterday it was not charging and today it was totally dead.
Thank you guys for the information
but what is different about the chargers? or USB cables I mean?
There are a few scenarios going on here.. (some of these things people have tried and got the same result, but i want to lay them all out on the table here)
A. The aftermarket chargers you are using may not meet the 5V 1A rating as the factory chargers... aftermarket chargers or even factory chargers for other devices such as motorola have an output of 5v 0.5A. Now the .5amp charger can charge the device just as long as its idle and not draining faster than it can be charged.
B. Defective Charger
C. Defective battery
D. Defective Phone
*Note- i did not mention roms due to the fact that phones will charged when they are completely off (not asleep)
Now that we have identified the possible problems we can start to identify possible solutions. (If your phone is completely dead and wont turn on then you may need to search for a thread entitled "Dead Wizard, Never lets revive" in the upgrading board)
Before you go to bed, turn the phone completely off and plug into the OEM charger that is rate output of 5V 1A, make sure the the orange charging light is on and go to sleep (you, not the phone, its off remember ) If this does not solve the issue then try this same thing with another battery and the same charger, if that fails, then try this the old battery and a new charger.....
If after you do all of this and its still not charging properly then your phone is defective.
if i didnt make much sense its cause i am tired and will clarify in the morning if i can
I'd like to make an observation here about some rather choppy battery life that I have been experiencing with my Wizard. I'd like to know if this is inside NORMAL behaviour parameters.
At 8AM this morning, my battery was disconnected from the charger with the battery fully charged.
Between 8AM and 11AM my total phone usage duration was 10 minutes. At 11AM, my battery displayed 91% Charge.
Then exatcly at 11AM, I turned on my Opera Browser and used it for 12 minutes, after which the battery dipped another 7% from 91% to 85%. I noted this reading at 11:12 AM.
After this I put my phone on standby. From 11:12 to 18:30 hrs, I recieved 1 missed call and a total of 2 SMS plus 4 emails. During this time I have not made or recieved any other calls. At 18:30 hrs, I noted that my battery was at 71%.
My phone is set to send and recieve emails every 15 mins. I have only one pull email account and one push email account.
Other than what I have mentioned above, there was no other phone activity. I do not have any background apps running except for SPB Pocket Plus and the Battery Status Application.
Please let me know if this is similar to what all of you are experiencing or should I get a new battery? My phone still has about 6 months of warranty on it? Will I be able to get a replacement for it on these grounds?

from what i can remember when i had my wizard i think that sounds pretty good actually...
thanks for that shogunmark. Do you have an approximation as to how much battery drain there would be for apps like Opera? 7% in 12 mins seems to be a lot. Also I have a feeling that if Opera is running in the background, the battery drains very quickly even though the device is set to go into standby after 1 min of inoperation. I can't confirm this but I have a feeling this has happened to me.
Also, since my messaging app checks for email ever 15 mins, how much of a battery drain will that be?

i cant offer an approximation since it has been a month since i switched to the hermes.. but i can say that i would pull mine off the charger around 8am and by 11pm i would need to charge.. but i used data heavily.. opera, pushmail, at LEAST 30 text a day, and maybe 45 minutes in calling a day. now 7% in 12 minutes does seem excessive, but running java apps is demanding on the phone, takes a lot of resources.

I can not aggree with this. I use my windows live and it syncs every 15 min I send out at least 300 txts a day and I use around 90 min of talk time during the day, (thank God for unlimited txt msgs and free nites and weekends). I use the web at least 40 min total and I listen to my MP3s on it on the train ride to and from work which lasts about 20 min from Manhattan to BKlyn. I dont recharge the phone the until I get home around 7pm charge for an hour and go out again.
I have noticed that certain Roms tend to suck out power much like my x-girfriend sucks out my money for Child Support. I have played around with running certian programs and adjusting the backlight settings and this has helped me keep the phone running all day.
My suggestion would be to change the rom and see if your drain contiunes. Then try to have your backlight turn off with in the 10 secs. If you are overclocking your phone when you dont need that extra Mhz turn it back down to 195 or if your really adventurous turn it down to the 170's for some extra power savings. Last but not least make sure your Active Sync is not turning on all the time by adding a fake server source. If all that fails buy the cradle with the spare battery charger and carry an extra battery. Good luck and godspeed!
Use 1A charger
This has been stated already, but after buying 5 extended batteries thinking they were all dying, I bought a 1A charger on ebay. Payed about US$25 shipped, but it made all my troubles go away. A reseller sold me my 8125 with a Razr charger and I thought it would be fine but it wasn't. Use a 1A charger!!!
I keep reading about this "Wizard draining battery" issue on here. I can't say that I've EVER had a problem with my battery draining.
I keep mine on the USB sync cable overnight to charge, pull it off in the morning around 8:30 when I leave for work. At that point, the battery is at 100%. Send/receive 4 - 5 text messages, 15 - 20 minutes of phone calls, PocketWeather updating every 2 hours, emails pulled from my POP3 server every 1/2 hour PLUS intermittent internet browsing and data entry into some of my apps. . . also running WA2 in the background. When I leave work at night, I still have between 77% - 83% battery life left.
Maybe it's just that I keep it "topped off" that I'm not experiencing any battery drain throughout the day -- I don't know. But, I've had no problems with mine.

Battery ran down in standby

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.

[Q] EPIC 8 hour max battery life -- is this 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.

Weird Batt issue, then fixed itself!

Samsung Focus (wife has one too) I use it a decent amount during the day, check emails all the time, surf some, read kindle books, BT on my 35m commute home, etc. Batt lasted all day just fine all day. I always charge it overnight with the charger.
10 days ago or so, got up to unplug it from the charger, and for some reason it would not start, it was dead showing the batt symbol. I moved the charger to another plug (first one is fine though) and let it charge all day, and it finally took a charge. But for the following week, it would be dead by Lunch, every day. I googled "Samsung Focus Battery Problem" and found a few peeps on various sites with the same issue. Tried several things to attempt to fix it. (removing battery, plugging phone into charger, re-inserting battery) Nothing helped. I'd have to connect it to my work PC to give it enough charge for the drive home.
Stopped by ATT shop, they agreed to send me a new Batt for free. I was not warm and fuzzy thinking that alone would help, but it was worth a try (it arrived today) before actually replacing the device.
So after a week of frustration, it was on the charger late Saturday and all of Sunday. Monday (yesterday) I take it too work, and its all fine again? By evening it still had 3/4 Battery. Same today. Weird or what!
I'll save the new battery for some future day, but for now the Phone is fine. Weirdness indeed, was it the phone, or OS or what?
Anyone else run into this?
Disabled feedback
I've noticed notible battery drain especially overnight and during the day with the feedback function in the settings section enabled. When it is disabled, my phones battery last forever...ok so it last till the next day at least, I am a heavy user. The funny thing is that when you soft reset the device the feedback automatically enables itself. I don't know if this might explain your situation. It seems like from time to time my battery seems to drain fast and other days it seems like i use the phone for the whole day and barely make a dent in battery life.
Nope, all settings have stayed the same, it does check my 4 email accounts at various times, I use Cellular Data all day, Wifi only at night (home). Habits all the same. It was a wierd bug, as confirmed by others during my search. Just dang happy it fixed itself.
I ran into a similar situation for the first time today. I've had my Samsung Focus for about five months. The phone gets light usage and has been handled carefully (carrying case etc).
Last night I noticed battery level was being reported as about 20% remaining. Normally I would have expected the charge to be at about 50%. I put the unit on charge overnight and this morning the battery meter was still showing about 20% remaining - essentially no change. I moved the charger to another outlet and tried to charge the phone a couple different times. I cycled the phone on and off and tried starting the charging process with the phone off. I also tried charging from a PC USB port. Nothing worked. In fact I started getting a message that the battery power was low, turn off phone to avoid losing data etc.
I checked on the Net for known issues with Samsung Focus battery problems. There were two suggestions that seemed worth trying; one suggestion was to sync with Zune, the other was to reseat the battery. I tried syncing with Zune first. That didn't seem to make any difference. Then I reseated the battery after I had powered the phone off. When I restarted the phone, the battery meter showed the battery as fully charged.
I don't know if it's a hardware, firmware or software issue, but there were enough reported incidences to lead me to believe that there is some sort of battery related issue associated with the Samsung Focus. If I had to venture a guess, I'd guess that it might be a problem with the battery contact design.
