*jump to ashtricks for immediate problems without reading software/ROM changes.
I know this is going to be made especially difficult with all the different software/combo's that can be loaded, but I have to post this up and see if any one else has seen this and if it might be hardware or software.
I have a HERMS 100 (8525). I first got the phone in April with WM5 (don't know which build they might have been on then) and which ever Radio was coming on them then. My battery would usually last 2 days with my avg use.
This has been the case threw upgrades until the last 2-3 months. I upgraded From one version of WM6 to VP3G's 2.X build of WM6 and I upgraded the radio to which ever version was the newest at that time (maybe 1.47 or 1.50). I Noticed a sudden drop in battery life, but the phone pretty much always made it a full day even with high use, so I didn't think much of it. I did notice about this time that sometimes the phone would alarm me and say it had 20% battery remaining, but if I rebooted the phone it would say 80 or 90% power remaining when it came back on and work fine the rest of the day.
The following has been over the last month. I upgraded to VP3G's 3.0 and again later to 3.6 and again to 3.62. I noticed the battery continued to degrade throughout this time. So I upgraded the radio to 1.54. The battery continued to go down hill at an even rate, but I noticed something else, the battery would not take very long to charge, but was dying faster and faster.
Well I started tracking and experimenting. Starting last week (no change in software or ROM's for the last 2 or 3 weeks) the battery would rarely make it through the day even when the phone was not in use any during the day (Granted I get no cell service at my desk at work, but I never have even back when the phone would last 2 days searching for signal). Most days last week it wouldn't make it 5 hours from being unplugged even when the phone wasn't in use. I decided to run the battery all the way down to where it wouldn't even turn the phone on anymore as I had heard sometimes you needed to do that after a rom upgrade. It did not help, but I noticed that the phone said the battery was fully charged within 2 hours from being completely dead.
*
Today was the worst, I unplugged it after being plugged in all night. Unplugged it at 6:45am. I did not use the phone, it just stayed in standby (I hadn't even taken it out of standby any today. I am at work with no service (When I say no service, I don't mean sometimes it finds something, I mean no cell service from any carrier makes it past 10 feet of the front doors entering the building and I am about 150 feet from the closest wall to the outside). I grab the phone at around 10:30am to check on a meeting notice, clicked on the phone to wake up and the battery alarm alerted and the battery said I only had 20% power remaining. In 5 minutes of doing what I was doing the battery had gone down to 10% remaining (so the phone went from lost 90% of it's power, never being used in less then 4 hours). I went back to my desk, plugged the phone back in and within an hour I noticed the amber light on the front that I relate it to telling me it's charging had turned green, I unplugged it and checked it and the battery said it was full 100%. Could the battery really charge that fast?
*
I know this would be easier if I could remember what radio and what version of WM5 came on this phone and loaded it back on and I am in the middle of downgrading the radio since I had ran WM6 with no battery issues separate from WM5 until I did that one upgrade with the radio. I guess I am curious if this could be a hardware (phone or battery) where it's not charging fully or if this seems to be a software issue.
I know all the factors that can be involved make this hard, but thanks for any responses you guys can give.
ok, how about this one, Is my battery screwed? I notice while I am using the phone the battery gets really hot. Today it did the same thing of all of a sudden saying I had 10% power after only using it for 5 mintues, rebooted the phone and now I am back to 70%.
Hi,
There's a lot on here about this problem. Have you read the wiki?
Some solutions you might try:
- turn wifi off.
- turn off all beams
- put in the fake server trick.
- search to see if you have any software that continuously polls the battery or is seeking an exchange server
- ensure all your apps fully close rather than minimise
- invest in a new battery.

Thanks, I have gone through the wiki Continuasly since I got the phone in April, but with all the stuff out there, I could have easily missed something.
- turn wifi off - Never turn it on
- turn off all beams - Beaming disabled
- put in the fake server trick - Have to research that one
- search to see if you have any software that continuously polls the battery or is seeking an exchange server - have to check, don't have exchange server setup. I do have it checking emails every 15 minutes, but I never had any issues with that setting and the battery lasting a couple of days
- ensure all your apps fully close rather than minimise - X button set to close not minimize and I often check it to see whats running.
- invest in a new battery. - Will be doing that next. Just waiting to see what case I might get for Christmas.
Thanks again, I will research those other items.
I had a similar problem where the stock battery would only ever last for ~7-8 hours - even on standby. I got an extended life 3000mAh battery and that managed to last for about 14 hours.
I had a talk to HTC and they agreed to warranty claim it. I'm still waiting for it back... It was sent back to them on 14/11, and I'm still waiting.
Stop your device checking for emails for a few days and ses what happens. Definitely install the fake server trick. Activesync continuosly trying to do its dirty work can be a pain in the arsenal, at times.
Let us know how you get on.

Well I turned off email checks last night and disabled the radio this morning so it wouldn't search for signal when coming to work and set the phone on my desk. I never used it this morning, just had it sitting on my desk in standby, until about 4 hours after I took it off the charger and the phone buzzed me and when I checked the phone the battery said 0% remaining and the phone cut off a few seconds later (now I am sure if I would have turned it back on the battery would say something like 70%, but I didn't do that this time). I left the phone off and plugged it into the computer to charge, the LED on the front come on amber for about 20 minutes then went to green. I turned the phone on and it says 100%. I don't see how the battery went from 0 to 100 in a matter of 20 minutes.
I did a lot of searching the last couple of days and phone issues from email to bad manufactured batteries (which I happen to have the brand someone suggested as a bad one), I also saw people pointing out do the fake server trick, yet I can't find a single time where anyone said what the trick is or how to do it. Not even in the WIKI where the trick was mentioned as a possible fix (or google for that matter, just the same words first posted in a thread here about it).
So, how do you do this server trick?
I plan to get a new battery after Christmas at any rate.
Check this thread:
http://forum.xda-developers.com/showthread.php?t=338421&highlight=fake+server+trick
I was having the same battery drain problem (less than 8 hrs on a full charge), I did the fake server and turned off auto day light saving time checking the clock settings, I now get 12 - 15 hrs on a full charge.
I'm running vp3G's 3.62.3 AT&T ROM with radio 1.54.07.00
Thanks! I was just finishing flashing a new ROM when I saw this. I did the fake server trick, but this rom doesn't have the Dya Light Savings time option where the instructions say it should be. Maybe that's all removed by this rom. TIme will tell.
Thanks again.
@ Firehawkns
hey buddy!!
I am using a JasJam for the last 2 months. i dont know if my reply is useful to you or not. As far as battery life is concerned am impressed with mine. Am using TNT's latest ROM and my radio version is 1.54.07.00. I use my phone all day with couple of calls that last about 2-3 min each. But every night I get calls from my gf, to whom I talk for 3 hours straight(mostly starting from 11pm to 2 am) and every day I put my phone to charge after I finish the call. So after finishing the call I still have 50% of battery. Moreover our call starts right after I leave work at 11pm so by the time I reach home which is around 11.30pm my phone connects to wifi too. So all the time am on the call as well as an active wifi connection.
So as per my experience the battery life is cool. So try TNT ROM!!!
Interestingly enough, now I've got my phone back from the warranty claim, it's only drawing 81mA with backlight on, no wifi or BT. Before sending it back, it was drawing ~180mA with backlight on, no wifi or BT.
This will just about double the battery life that I get in theory...
Install BatteryStatus on your device and see what it tells you.
That is a cool program.
First off I really hope it isn't the phone, for one it's my third one from Cingular since the first two died within 2 weeks (back in may), second it's got one big gash down the corner where it came out of the holder and hit the road one day. I think that would be just enough reason for them to not do anything with it.
Anyway, I am going to replace the battery because I can't figure out why the phone is doing things like saying it has 20% batt remaing, then I reboot and it goes to 70%. I am hoping this is a battery issue. So far the phone has been unplugged for a tad less then one hour, has not been used and the battery meter is on 90%.
Battery Status is a kick butt program and I plan to do some searching today to see if people have benchmarked there ratings/draw. I notice mine jumps randomly. With wifi, BT, all programs all terminated, backlight on the lowest it will go and radio has one bar 3g sometimes, two bars Edge sometimes, but didn't change during watching this list below, but the MA does this every 5 second refresh:
111--190----125-----109----250----210-----140----135----226---111---etc.
I am currently running a barebones fresh flash WM6 rom with nothing installed except Cingulars media net/ISP settings, radio is 1.47.10. Going to try 1.50 today I think.
I turned the radio off just now and the MA went down (expected) to 84 and is jumping between that and 104. The battery has dropped to 80% since I listed 90 above. The phone has now been unplugged for right at an hour. Also it might be interesting to note that the little battery percent/bar icon on the "Battery Status" software once in a while will display -1% like it is right now, the phones battery display says 80% and when I tap the battery icon on battery status it jumps to 80%.
Anyway, I am just listing points since this thread is here, I know I need to replace the battery first before any additional insight can be brought forward.
Thanks everyone.
Hmm.. On my Schaps 4.22full, radio 1.54.00 on good reception (on Finnish network) I get around 30 mA with GSM and 3G when idling(no wifi, no bluetooth, no beam, backlight around halfway). With airplane mode on I get around 28 mA. Tried with backlight dimmest and the drain was 15mA on GSM network.
Usually I put the 3G off so the battery would last longer.
The phone takes more power when searching the network so it would be a good idea trying to switch the phone part off at your office.
Well, looks like it was indeed the battery. Over the last week the phone would randomly shut off (about 4 times a day), the battery would be at 10% within 4 hours even if the phone hadn't been used, and while using the phone you could almost watch the battery go from 90% to 30% within a 5 minute talk time, reboot the phone and it would be back at 80%.
Put in the new battery yesterday after charging over night and the phone not only didn't shut off at any point, but I had 60% power remaining by the end of the day (with some data and voice use).
The old battery was a Dynapack from China, that I had read on here is prone to defects.
Thanks for the help everyone, wish I would have gotten a new batt sooner.
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 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

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:
siliconaddict said:
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.
If y'all are really interested in reading a 51 page thread on this, go here: http://forum.xda-developers.com/showthread.php?t=755903
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.

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

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!).

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.
Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.

this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
Does anyone have any suggestions on what I can do to test which one might be bad? Any app you know of that can monitor things and tell me if a rogue app is killing the battery or if the battery is bad?
I was running mik 1.1 and was using it pretty heavily with gaming and downloading stuff. The phone died after about 7 hours. I thought that maybe the rom or cwm or something else might be killing the battery. Something strange though is that, like I said, I ran the battery until the phone shut off. Then I left it off and put it in a wall wart charger for about 8 hours and the status light was still orange. My gf had the phone and told me once she left it plugged in overnight and in the morning it was only at like 50 something percent. I thought maybe the charger went bad so I gave her another one and she didn't say anything else about it. I'm starting to wonder if maybe the phone's battery has a weak or bad cell. I kinda doubt that there's something wrong with the charging circuitry of the phone but there could be, anything is possible. I will probably take it to the repair center and tell them about it and see what they say. I tried looking on htc's site for oem replacement batteries but couldn't find anything. I found lots of aftermarket but I didn't want to go that route.
I don't know if it would not be a good idea or not to try and use my original evo battery just flipped over. I suppose if that's the only thing I have to try and troubleshoot this problem then it will have to do.
Can anyone give me suggestions or has something similar happened to you?
Now let me see if I can find that evo battery..........
Spare parts, in the market if not on your rom by default, had a battery information tab that will indicate battery health as well as what kind of plug the phone detects when charging (usb, ac, or none)
Sent from my PG06100 using XDA App
Like danaff37 said, spare parts can be useful. Also try CPU Spy, free from the market, which shows what % of the time your CPU spends at each frequency, but this actually more relevant for determining if your phone is properly sleeping..
For proper charging you can get an app like CurrentWidget or Battery Monitor Widget which tells your the current consumed during usage or current injected during charging, as well as the voltage in mV. Full charge should reach around 4200 mV, and when charging the current should be around ~800 mA for lower % battery left.
Thanks for your input. I found the evo battery and did the same thing as before. I ran it until the phone shut off and then put it one the (same) charger and went to bed. About seven hours later, it was still orange charging. Both times the phone was off. Now something that could be a possibility is the charger is weak or bad. When I put my evo on it, it charges seemingly fine. I should try using the battery until it shuts off again and use a different charger and see what happens. Six to eight hours charging, with the phone off, coming from a dead battery, on a Motorola charger that has a rated output of eight hundred milliamps at five volts. I have others at different output rates and a two amp charger intended for an ipad. Some might say that the charger is too much for the phone. The charging circuitry only pulls as much amperage from the charger as the phone was designed to. Now on the other hand if I put a smaller output charger on, say one hundred and fifty milliamps, it will take longer to charge the phone than usual. "They" say trickle charging is better. Whatever. I will post my results if I find any. Or, I just might trade the phone in for a nexus s or an evo 3d.
I was just about ready to throw in the towel and say the phone was defective, but then things started happening. I will fill you in on what I have done in the meantime. Okay so the flipped over evo battery kinda works but not completely. It will charge but not to 100% and green light. To test this, I took the evo battery out of the shift. It didn't seem to want to go more than 98 or 99%. I put the battery into the evo and after a few minutes the light went green. This was initially off. Then I booted the evo and let it go to sleep. After it booted the light went orange then green after a few minutes. Okay so the evo battery is capable of going to 100%. These charging tests were done with a different charger.
I forgot to tell you, I let the evo battery charge while I was at work and the phone was off. So the battery was charging roughly twenty hours and still no green light. I suspect that even though the positive and negative terminals aligned with the correct tabs on the shift, the center two contacts must be different internally than the shift battery. I speculate that those center tabs are for the battery and phone to communicate to each other during it's charging state. I am guessing that the battery tells the phone it is fully charged and to go trickle charge and perhaps the evo battery wasn't communicating to the phone or the phone didn't know when to say it is done charging. The battery never got hot either.
The shift was rooted, running mikshift 1.1 and the latest clockworkmod recovery. Here is where I suspect that there still might be charging bugs with that setup. I used the pcxx.zip file that when booting into the bootloader, would flash the phone back to stock everything. After trying this and assuming that the phone was back to stock, I kept going with my what the hell is going on with this phone battery charging test. A note about the flipped evo battery. Yes it will work in a pinch but it won't charge properly. Luck has it that the notches in the battery and phone allow it to work in a shift. Only thing is, the shift battery won't work in the evo. The tabs are on the wrong side and the phone's tabs won't allow the contacts on the battery to meet up with the phone's terminals.
Okay, where was I? Trying different chargers wouldn't make the shift green light full charge. I tried the same chargers on the evo with it's original battery in and it would green light after a few minutes on or off. There wasn't anything wrong with the chargers. Oh and another note, while using the battery monitor widget, I noticed that both phones wouldn't pull more than a little over three hundred milliamps of power from the charger to the battery. Interesting to know how much it really pulls from the charger.
Anywho, I tried something different for my process of elimination testing. I actually ruu flashed the shift back to factory and guess what happened..... The battery and phone were charging both on and off all the way to green full charge at 100%! I think I'm getting somewhere with this! All my luck, either it is a known bug somewhere in the forum in a place I haven't stumbled across or I'm the only one that this is happening to. It doesn't really matter I guess.
My conclusion, which isn't scientific by any stretch of the imagination, is that the phone isn't truely back to factory unless you ruu it. The pcxximg.zip doesn't put everything back to stock. I haven't narrowed it down to what is causing this behavior. I don't think it is root. It could be cwm recovery or the rom or both. I didn't try the stock rooted zip either. I suppose I could go further with this investigation but I am too lazy to now. I might root it again and just leave things stock rooted. I might activate this phone in the morning and run it all day tomorrow and see how it acts. I will have to charge it a few times during the day to keep the levels up when I really use the phone heavily. I've written enough for now. Does anyone have anything to ask or add to this topic?
Since the latest update to CWM phone-off charging finally works again but the light never turns green. It charges fully but with the phone off the LED never turns green. It's not just you.

^ Shift Faced
OK. I thought something might have been broken.
Forgive me, I am truly a newbie to Android after having a BB for 8 years. This battery thing is killing me. I am on my 2nd Evo Shift, the 1st one wouldn't last for more than 2 hours with barely any usage so they gave me a new one. This one barely lasts 5 hours. I am barely running anything. I took it into the store and they thought I was going to be running all these programs, but I kill everything. They told me the "battery trick" about turning off the phone and unplugging it and plugging it back in 10 times so I did that but I am not getting any more life out of the battery. My display is constantly using at least 70% of the battery it says even if I turn it down very low or if I set it to choose its setting. Do you have any advice for me? I am not running a task killer, I kill all the programs I am not using. I have no widgets running because I am afraid to use the battery, I only have 2 screens out of the 7 with things on them. I am being help hostage by my cool phone that I want to use but am scared to kill the battery! (sorry for the long post)
Ok if you use a lot apps just close them after (for stock 2.2) . Even on stock you can literally stream music and movies for about 4-6 hours. (sometimes a lot more) . The background info that runs doesn't use a lot of juice , but if you want you can go to your home screen any of them hit menu (but not with the app drawer open) select settings go to accounts and sync turn off background info and just turn it on manually when needed such as the android market . You can also turn off the auto sync and just manually choose to sync , like in the clock (and gmail etc.) it will say no weather after you click it , just hit menu you will see a little sync button option to sync and voila you have weather . So when you visit the market it will automatically ask you to turn it on (background info as will all apps that need this) . And the screen on any android is a battery killer . So when not using your phone simply tapp your power button to turn your screen off and lock (and to keep from pocket dialing lol) . But if all you do is text , emails , and web surfing (surfing drains more but no where near as much as streaming) you can literally do that all day , the screen will actually suck the most power . If manually turning off your apps is too much . Just turn your phone off (not just the screen) and on . If a new app didn't turn off after you start your phone back up you know that will be a problem later . So when not using your phone turn off your screen it will last soooo much longer . I only make a call or two and a couple of texts maybe a few minutes of internet with opera mini . My battery lasts over 24 hrs , but I barely use my phone . Hope that helps .

BTW if you have a bunch of apps running in the background video games etc ... and you charge your phone all night and in the morning it is not charged . You should probably turn your apps off . Or simply power your phone off which shuts off most apps . Then turn it back on . The phone should not take all night to charge , it should only take an hour or 2 . 3 hours max .

i suggest watchdog lite,it monitors cpu usage and alerts you when 1 uses more than your max threshold.if this helps,please click thanks.
When you changed ROMs, did you do it with a full charge? If not, your battery stats file is probably messed up.. Ive used Battery Calibrator free from the market in the past to fix that problem.. I believe a brand new battery on the Shift shows about 4200mV when fully charged or just slightly below that.. Run the app, when it gets close, calibrate (which essentially just deletes the battery stats file and creates a new one)
