Hi,
I just flashed SuperClean 2.9.2 (non-voodoo) yesterday, and I love the speed, but it really drains the battery pretty fast. For example, with minimal usage it drains from 100 to 82 in less than two hours. That's a lot worse than the stock settings I had on there before. Since I'm new at this, is that normal? If I switch to a better kernel would that fix it? Any suggestions on what to do or tweak?
Thanks!
[Update] 3/30/11
So after a full day of observation, I've noticed that it seems to go from 100 to 80 fairly quickly (less than 2 hours), but then the rate slows down. It took 4 hours to go from 80 to 62. Then last night I left it on all night, starting at 78 and it is now at 48 (almost 12 hours). Obviously I wasn't using it much overnight, but I wasn't using it much when the initial drain from 100 to 80 happened. Might just be that the meter is not consistent? But at least I know that it's not draining faster than the old setup.
Still looking into the idea of an undervolted kernel. Any good suggestions?
Thanks!
An undervolted kernel might help but who knows... if I get over 5 hours I usually consider myself lucky.
i updated this morning, have an extended battery, and seem to notice massive drains, but i guess with power comes sacrifices

5 hours?! Dude, that totally sucks! Hmmmm, maybe it's time for a new battery?
Mine lasted about 6 and a half hrs then was at 8%

Not sure why this double posted. Must have been my frustration waiting 5 minutes just to edit an already posted post to correct the name of the app....
Each phone reacts differently to ROMs / Kernels when it comes to battery life. Same setup shows different battery life for different people.
First I would use the "Spare Parts" app and see if you can find any app taking up a lot of your battery life and remove it. (included in SC ROMs)
People also report different battery life with different Kernels. You can flash different Kernels that work with your ROM to see if you can get better battery life.
You also may need to remap your battery. There are posts on how to do so. Basically you charge to 100%, shut down and wait for it to show 100% with power off, then boot, go into Terminal gain SU and type bstats. Phone will reboot. This should be done anytime you flash a new Kernel and some do it with ROM flashes too.
Also don't run screen at 100% bright, use auto or something at or less than 30% unless you are in sunlight.
When not in use turn off WiFi and GPS as well.
All I can think of right now

I know some of the kernels are designed to recognize an aftermarket battery (see link below)

Running not even 2 hrs yet and mines at 70% right now from a full charge, so I feel your guys(gals)' pain. I checked with Spare Parts and noticed that under "Network Usage" there is a "0" that seems to be using up a LOT of juice. Searching it up on google brought me to a possible issue with GSM/CDMA (Time w/o signal issue). I remember issues with this with the D1 and the Eris, usually you could fix it on those phones by turning on Airplane Mode for a little while, then turning it back off.
EC10 is based off a GSM SGS phone if I'm not mistaken, and because of that may make the phone try to find a GSM signal. My time without signal was around 45% this morning so I dug around threads with similar issues with other phones brought me to this Hero CDMA thread: http://forum.xda-developers.com/showthread.php?t=651848 .
Now we do have the same menu as shown here: http://forum.xda-developers.com/wik...sung_Galaxy_S_Series&oldid=13336#Secret_Codes
My thing is that I can't access it using SC 2.9.2. It doesn't automatically go to any of the menus. Anyone else have an issue getting into any of the secret menus?
It also looks like turning the airplane mode on and off seems to work for now.

Read like 20 threads about the "0" and came to no conclusion haha. People just said it means root... and it could mean any app that requests Super User/Root permissions. Who knows though... I'm about to wipe date and reinstall afresh.

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

Spare Parts says "Time spent without sleeping: 53m 15s (100%)

If I go to Battery History and change the top dropdown to Partial Wake Usage, it says Android System at the top with a bar that's at least 75% full.

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.
I hate to start a new battery thread but I've searched, read all the ones out there, and nothing seems to have helped. I just got this phone late last week and I first upgraded it to the latest OTA, then odin cww and finally installed com rom 1.3. Let me just say I've never seen a battery drop this quick. I haven't even activated the phone on my account because I'm so scared of how quickly I see it dropping without touching a thing on the phone. I also noticed the following:
baseband version
S:i500.04 V.ED03
Kernel Version
2.6.32.9
Build Number SCH-I500.ED01
The baseband and build ED0? don't seem to match up. Would this cause the problem? How do I fix that?
Just so that you get an idea, I've had the phone disconnected for 5hr 30min and I'm down to 55% battery with a fresh clean install of com rom 1.3. I did the battery calibration and that's about the only thing I've even installed on the phone. When I hit batt use here's what I get.
Display: 52%
WiFi 26%
cell standby 15%
Phone Idle 7%
I've had android for about a year and have an incredible that I love so I know that something just isn't right with this fascinate. Any help is greatly appreciated.
Thanks,
Mike
my understanding is that the build and baseband don;t have to be equal, baseband is modem/radio and build is just the rom i believe.
From what I hear, the only thing you have to keep track of is using an eclair modem with a froyo rom as there will be issues...
You can try going to the ED01 modem (works better for me vs ed03)
I also had battery "problems".. barely get through 12 hours without needed charge with little use.
I just installed Green power app from market.. it seems to work similarly to juice defender, just is easier to configure for the noob like me, and is MUCH more limited. works on the basis of only turning on transmission intermittently.
Now I can go 18+ hours and remain above 50%.. 80% if I don't touch my phone.
Turn off wifi when you're not connected, my phone lasts 36 hours using juice defender to turn off radios when screen is off

The radio firmware makes or breaks the battery life on this phone. I've tried every combo of roms and radio firmwares. Go back to the DL09 or EA28 (my preference) radio firmware and recalibrate your battery bro. The eclair-era radio firmwares have proven to be much better than the newer ones.

Com Rom is built off of ED01 so it will say that.
ED03 is the latest build basically the same as ED01 just 3 fixed some bug that had a few phones stuck on EA28 if I remember correctly.
I haven't noticed much battery difference between the different modem/radios, personally it seems like the kernels make a bigger difference to me.
Also if you just clear the battery stars to calibrate the battery the battery gauge will be messed up for a couple cycles, best if you run it all the way down too. One of tie batteries I was calibrating in my phone said 0% for almost an hour before it actually turned off.
These phones aren't great on battery life anyways. One of the good things about using a kernel like OTB included in com rom is it allows you to use aftermarket batteries and still charge then in the phone. I get the Samsung batteries (I think they are technically for the epic), out of China for $2 each. Have 5 of them right now the wife and I rotate through. We also have two external chargers, we both just carry a spare battery to use if our phones die during the day.
Thanks for the tips. I think I'm going to try the different radio files and see if that helps. I guess I was just wondering why my display shows as if it's using so much battery and if that was caused by some other conflict. I've had phones with bad battery life but this is just crazy. From the time I wrote the first post (a little less than 2 hrs ago) I've gone from 56% to 36% with nothing installed or running. That's just beyond bad battery life. Something is hosed. I'll try the radios and cross my fingers.
Have you tried under the task manager and choose the ram manager do the level 2 clear, should close everything that is running, that helps me quite a bit. Also auto rotate can be turned off when you aren't using it that will help battery life too.

As was stated earlier, turn off wifi when you are not using it, that will help a lot. Also under wifi settings, advanced, and change the wifi sleep policy to when screen is turned off. And when you look at those percentages under battery use are not a percentage of the total battery, just a percentage of whatever battery use there is. So if you are losing 8% of your battery per hour, that 52% next to display just means display is draining 52% of that 8% per hour drain. Display is almost always going to be the top drain because of the super amoled screen.
^^^ Yeah, display is most of it. Turn brightness down (as opposed to automatic or full brightness) and see how that helps. If that doesn't help, turn off mobile data until needed, if that doesn't help (should do this anyway) recalibrate your battery and cycle it like 2 times. Give it a couple days, it will go back to normal.
Radios are the biggest battery drain, not the screen, I've used airplane mode and watched movies with four hours of screen on time and used 20% battery, all you need to do is keep wifi off when not in use, it pings something like every 20s trying to find when you're in range of networks, 3g is your second biggest killer...also do not use auto task killers, for reasons I'm too lazy to get into...lowest screen brightness setting helps some but I've found it a pain going into bright sun and having to change it, the auto dimmer works rather well

Click on the items in battery stats and tell us how long your display has actually been on. The display on this phone can fairly easily burn through 1%/minute of being on (in fact, doing the math, my phone's display is at just under 1%/minute right now).
And, personally, I hate JuiceDefender and those apps. They're not fixing the source of the problem, just doing a half assed job of duct taping over what might be tangentally related (while doing horrible things to syncing). Try to find what is _actually_ trying to keep the network awake if that is actually what is going on (the Facebook widget is known to utterly destroy battery life). Make sure apps are using Push instead of Pull notifications where ever possible (Pull uses an astronomically large amount of battery life in comparison to Push).
I get around 15 hours on any other radio than dl09, on which I get around 24-36 hours depending on how much I'm using to phone. Also make sure you turn off wifi when you aren't using it.

Ok, thanks to everyone. I wanted to give you all a quick update in the hopes that this will help someone in the future. I replaced the radio file with EA28 and wow what a difference it made. I now don't see the percentages drop right before my eye and I have a shot of making it through the day. I'm also pretty surprised by the amount of battery the screen uses up. My AMOLED droid incredible usually shows the display as using the least percentage of battery. I guess the super really isn't that super.
One question I do have is if I go back down to DL09 to get the better battery life, what's the trade off?
I haven't noticed any differences between the DL09 radio and any Froyo radio.

How can I make my battery last longer? I am using set cpu and various profiles to give me the best optimization I can, however my phone barely makes it 10 hours with light use *1hr web browsing, avid txting, light music listening via music on phone ~ 1 hr as well.* I'm not faulting the phone. I just want to know what can be done to get the most out of the stock battery as I see people getting results twice as good as mine and just done get what I'm doing wrong here.
Thanks for the help in advanced.

I used cm7 for a while now using UnNamed and cm gave marginally better battey life but
Just use the dang phone . You dont need to do anything special for great battery life. Try a factory reset if theres a problem though. Im rooted on cog beta 4 getting amazing battery life. I talked my mom imto getting this phone over the new iphone and hers is completely stock and she knows nothing and doesnt close any apps and gets the same amazing battery life as i do.
Reset and use it. If you cant get through a day of heavy use the phone is defective.

+1....or you have wakelocks. Find BetterBatteryStats and CPUSpy. BetterBatteryStats will tell you if something is preventing the device from going into deep sleep. I like to use "wakelocks since unplugged." CPUSpy will tell you the amount of time your device spends in each frequency, including deep sleep. For this, you'll need to reset the timers each time you unplug the phone.
Its add easy as flashing cm.... I went 15 hours and still had 60% left. with OC. Nothing else special (aka no juice defender our set CPU). The only trick is deleting everything in the dcim folder (known medias bug ) you'll see 1% battery loss per hour, with fb and GV sync

I have a car charger, home charger and work charger (as do most people)
Thanks for all the replies. I'm sure there's go to be a work around for this
Not sure about a workaround. From everything I've seen, the max battery life is around six hours when the screen is on. Basically, if your screen has been on for 4-5 hours, it's time for a recharge.

Well based on all I've read it seems like the battery is a mixed bag depending on the OC profiles, roms and kernels being used with the device.
Is it true that setting a screen off profile in set cpu will cause the device to not be able to enter a deep sleep mode and thus will kill the battery faster?

Not true. It is true, however, that on stock kernels and ones without the "sleep of death" fix, setting a screen off profile with a clock limit lower than 800 MHz can cause "sleep of death" issues. Right now I think only my kernel and the Cyanogenmod kernel have the SoD fix.

Thanks for clearing that up
I'll post here as I don't have enough posts for the development forum yet.
I'm running Entropy's 16th exp kernal, and Cog4 and I noticed my battery draining far too fast, CPUSpy then showed that the phone simply isn't entering deep sleep. I had previously been undervolting with Voltage Control but I uninstalled the program just to be safe, still not deep sleeping. I also uninstalled Widgetlocker, and I don't think I have any apps that would cause infinite wakelock. What are some possible causes of this issue? Just so I have an idea where I should be changing things.
UPDATE: Reflashing the kernal fixed the problem for a while but then I reinstalled voltage control and now I seem to have it again. Uninstalling and reflashing again however, did not fix the problem. I am utterly confused
On another subject, has anyone actually noticed better battery life after undervolting?
Freaking SWEET! My battery lasted 33 hours and 13 minutes! I've only owned the phone for 3 days now and this is off of teh very 1st FULL charge! Usage was between light & moderate. Data sync on, Wifi On, GPS OFF, BT OFF, FB Data Sync OFF, Capacitative buttons set to light up only in the dark & NO haptic touchback...mmm, can't remember what else I tweaked at the moment but I think that's fantastic battery life! I'm upgrading from a G1 that couldn't last more than 17 hours when it was on standby ONLY with maybe 2 phonecalls and less than 20 text messages. I usually only averaged 6-8 hours and with SIMILAR usage in the last couple of days, I've been able to get 33+ HOURS? ^_^ <-- I'm very, very happy so far! This is on a stock root - NO custom ROM for me at the moment...I'm actually digging TouchWiz 4.0 which I thought I was going to hate when I played with the previous version of TW on the T-Mo Vibrant. (yes, my G1 was running CM 7.1 and battery life still sucked and I went through 2 different aftermarket batteries w/o any luck!)
Don't know what the voodoo in the programming is with this bad boy, but I think Sammy did a nice job this time!
The best thing you can do is having "Autostart" to prevent App to start automatically. I saved 25-30% on my SGS 1 and the same on my SGS 2 (i777). My son on the I9000 SGS 2 saved also 30%.

Check for wakelocks in BetterBatteryStats, and if that doesn't find anything, do the following in an Android Terminal Emulator shell:
Code:
cat /proc/wakelocks > /sdcard/wakelocks.txt
or better, using ADB (Google it and if you're on Windows, Droid Explorer)
Code:
adb shell cat /proc/wakelocks > wakelocks.txt
Then post wakelocks.txt here
All the apps,camera n everything works on that rom? ??? I installed cm7 bt now stock it cuz some apps and camera app didn't work.

Hello all,
I bought the Atrix around 6 months ago and I have always had the same problem I'm about to describe. First I should mention that I used to have a stock rom and stock radio (77.15) until a couple of weeks ago when I flashed Cyanogenmod and radio 77.30p, yet the problem is present in both configurations.
My problem is as follows: my battery life is mediocre. Without using the phone very heavly, I get around 7-8 hours until it shuts off. Since day one I've tried many different fixes to see if the battery improved without success. Now here's the fishy part: for whatever reason, every time I make a full wipe (when I was using stock I did it from the "reset to factory defaults" option, now I do a full wipe on recovery) the battery lasts an insanely amount of time, something like 24 hours or more.
Here's how it usually works for me: I do the wipe, I boot my phone and configure my accounts, the phone syncs and installs the apps I usually use. Like I said, that day the battery will last forever, last time I've tried this I reached around 31 hours before I plugged the phone back on, and it was around 17% still. Now, the next day, without installing any new app or using the phone for nothing different, I go right back to the mediocre battery life. For example, it just went from full charge to 88% for just 10 minutes of browsing the net on wifi, not even using 3G.
Like I said, this happened with stock ROM and now with Cyanogenmod regardless of the radio I'm using. I have calibrated the battery a million times, I've tried with Watchdog which didn't show nothing, the same with Better Battery Stats. I really need some suggestions on what to try because it irritates me that the battery is dropping so much with such a light use.
Thanks!
I'm getting also quite short battery life with CM7. I'm wondering what the reason could be. It gets down with 15% for just 5 hours without any phone calls. I have just whatsapp and email checking every hour. No other resource hungry applications. With the stock ROM and the same usage I'm getting around three days ~ 72 hours.
Well in my case it's the same but with both stock and others roms. I suspect it's a software problem because I get normal battery life when I do a full wipe.
Did you try to revert back to unlocked bootloader.
What I found strange is that somehow the indicator doesn't show the ratio mAhercentage. On 85% battery the calibration battery shows charge 4030 mAh which is not 15% less than the full charge of 4200 mAh.
Well actually this problem has existed from before I unlocked the bootloader so I don't think that's the problem. And in my case the mah percentage is correct. It's like if somethings draining the battery that I can't find. Maybe is a problem with my carrier?
If the coverage is poor where you live then it is possible to get lower battery life than expected. Another solution is to revisit the application you use, try also to do a full wipe including formatting the internal memory card.
Go through this process: http://forum.xda-developers.com/showthread.php?t=1198333
You'll be good to go after that. Check also BetterBatteryStats here in xda, will show you what processes eat the battery.
Thanks but I've tried that when using the stock rom and it didn't help me. I think that solution is for a different problem as it's mainly to display the correct mah percentage, which is not exactly my problem. Also, CM7 already includes juggernaut fix.

Have you tried a different radio?
Yeah, like I said I had 77.15 at first and now I'm using 77.30
There's more radio's, check in General.
Ok, I flashed 77.36p and there was an improvement, I've unplugged the phone around 13 hours ago and I'm at 25%. Would you consider a good battery life for a light use? It's getting better but I saw many people crossing the 24 hour mark on their phones. Are there any other radio to try other than 77.15, .30 and .36 that would be worth it?
Do a full wipe in Fastboot & install Nottach's DarkSide and leave it with the stock kernel. I'm at 77% with 1hr 40 minutes screen time & 17,5 hrs standby..
P. S. I'm using the N_01.100.00R radio. Am in Germany, though on an at&t phone. Best radio so far.
Anywhere from 13-20 hours is fine but keep in mind it's all dependent on what's on your phone. If u have a bunch of apps pulling data from the internet or something ....I mean its all dependent on your phone setup.

Well, for now I'll stick with Cyanogenmod for a while because I really like it, but I have flashed the radio you've mentioned, we'll see how it behaves. Thanks!
I've read and read, searched and searched this forum and have not come across my exact problem yet...
I know there have been overheating issues, and I know there have been boot looping problems... all causing terrible battery life, mine has neither. Let me rephrase, my overheating issue is not due to me actually using the phone... On idle (with the screen off), my Rezound only lasts about 2 hours on a full battery. Granted, I live in an area where there isn't full service, but there is some service. I can watch as data is being exchanged with no apps running. What the hell is using data? I have a feeling this is what is killing my battery, the phone is not at all sleeping. I have deselected "always on data" and I turned off fast boot and auto sync.
Any suggestions would be greatly appreciated.
BTW, my phone is a bone stock refurb.
Try a factory reset maybe?
I can do that, but it doesn't really solve the problem. It just started doing this yesterday. I've had it over 2 months and haven't downloaded anything different. I would really rather just figure out what is causing it, so I don't have to do a factory reset every time something like this happens. You know? Thanks for your suggestion, I'm afraid that is going to be my last resort right before exchanging it...
Try exchanging the battery first. Start small. Work your way up to the big stuff(exchanging the phone). Why give up the customizations you've done if you just have a bad battery?
I was thinking it may be a bad battery, but it concerns me that I can watch the data stay running even though I'm not using anything that requires it. My brother has a Rezound and I placed mine next to his and literally watched the battery life deplete 10% in 5 minutes while his lost no percentage at all, both were idle with the same screen settings. Is it common for a battery to fail that drastically out of nowhere?

Is it common....no, possible yes, plausible given the circumstances....absolutely.

If data is constantly being used, something HAS to be using your data. I'd get an app like better battery stats and CPU spy. CPU will show you if your phone is going into sleep mode at all and better battery stats can show you which apps may be causing it.
Do you have the 4G antenna on?
I have betterbatterystats, it shows android system at the top of processes. That program is a little difficult to understand since everything is abbreviated.
I appreciate all of your responses. I just got off the phone with Verizon, they're sending me another phone AND battery for good measure. During lunch today I watched the percentage of my battery deplete while it was plugged into the wall and not being used, used a different charger, nothing. It wasn't even hot. I turned the phone off to try to get it to charge. when I turned it back on, it got to the lockscreen and then restarted itself. Boot looping now. I'm not going to fool with it anymore. Maybe the third Rezound will be better.

I haven't changed anything from out of the box other than visual properties. I'm assuming the network has a little to do with it, but it started failing way too fast to be a radio problem IMO.
I received my 2nd Rezound last week. First one had the hiss/feedback/interference issue through the headphone jack that escalated to a level of to not being able to use the headphones at all without being painful. Anyway, the new one is running very hot (battery) and is draining the battery almost as fast as you're describing yours to do. I've used both the standard battery and extended. This morning while using it at home on wifi with most of my syncs either disabled or set at a min of 2 hrs it drained my extended battery by 20% in 20 mins. I wasn't even using the internet or streaming any music or video. I was working on setting up calender and task list widgets. Phone is stock, not rooted. I will be calling Verizon tonight to see about getting a 3rd one. Sucks as I really like this phone when it's working properly. If the 3rd one has issues to and HTC isn't rolling out any fixes for them I might have to look at something else. But I don't want to!
I feel like if I can get the hardware to cooperate with me, I can get the software to. I was planning on rooting after the ICS push, but the phone obviously had different plans.
Set your phone to CDMA only, especially if you don't live in an area with LTE coverage. You will see significant battery advantages from that alone.

I should have mentioned that I'd already done that (only 3G here anyway). I've done all the battery management tricks I've read about but this phone has an issue. I'm not even getting half the battery life out of it that I was on the 1st one. And the battery gets significantly hotter then the other phone.
tried wiping battery stats after 100% and drained/recharged a few times?
