Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?
Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

I had the same problem with my Bluetooth recently. When I try to search for devices the phone locks up and I have to pull the battery. Wonder if this is a kernel issue. I am on snap

Yep, I'm on Snap too; must be it.
Another thing; I've got a friend on Stock 2.2 Sense (battery sucking widgets filling the home screen, etc) with 100% brightness and mobile data constantly on and he gets better battery life than me (20+ hours!) What is going on!?!?!

I couldn't believe it either, he had 3G on all day and everything and we barely get any signal at all in class. On for almost 8hrs with more than 70% left. I was at about 53%
Firstly, I know what I'm doing when it comes to flashing. But I'm completely dumbfounded here..
Okay in standby mode, with wifi on i usually get -3 to -7mA.
But suddenly a few days ago, my phone doesn't sound my alarm in the morning because it had turned its self off.
Imagine my surprise when I had to plug it to start it. Turns out it had drained 60% in little over 3 hours.
So I began testing - turns out my phone had started to fluctuate between -90 and -150 mA EVEN IN AIRPLANE MODE.
After trying countless solutions (inc many different ROMs), I had had enough. I full wiped from CWM and installed fresh ARHD 5.1.6, skipped all setup, installed just titanium, and restored just battery calibration and currentwidget. I calibrated and then left it overnight in airplane mode - and STILL it fluctuated just as wildly.
I wouldn't post this if I hadn't tried everything, but I have spent hours reading xda trying to amend this. Changing radios didn't help (am using latest atm), changing ROM didn't help (not GB or froyo or CM7), even restoring my nandroid from when my battery drain was normal didn't help.
Does anyone have ANY ideas as to why this is happening?
The only thing I can conceivably think of is that my battery is giving up.
Is this good enough cause to get a replacement battery/phone from HTC?
Edit: Meant to post this is Q&A tread, sorry
if you changed the ROM and radio, then i'd be near to positive to say that the problem is from the battery!!
Buy another one and give it a long 20-22 hrs charge (although HTC recommends 8hrs - but they talk alot of crap ) before opening your phone.
Or, alternatively, see if anyone (friends/family) can lend you a battery and see if the problem still persists

Official batterys are expensive... does HTC do replacements?
not sure, never tried or asked, gotta phone them up!
have you tried turning USB debugging on? that solved it for some people.
i also had this problem, and the USB debug didnt work, but i found that it was something to do with HTC hub repeatedly trying to connect to the internet and using a shed load of CPU in doing so. aeroplane mode didnt help me either, but after turning off everything with HTC in its name it worked again. (specifically HTC sense in accounts and sync)
hope that helps, worth a try.
oh and my battery is fine now, lasts 2 days or so. can last a week though.
still charge it every night though.
Thanks for replying, but USB Debugging was always on for me, and when I tested with fresh install I didn't put ANY accounts in so the HTC thing shouldn't be an issue. i guess I'll just try the replacement battery thing
sometimes the radio signal kept switching also may cause a drain in your battery.
Setting > Mobile networks > Network Mode > Preferred Network Mode
for me i preferred it to be set as 'WCDMA' rather than 'GSM/WCDMA Auto'. The draw back is that i may lost signal if the signal is weak but this setting prevent the radio from being switching.
OKAY GUYS I FIXED IT
How you may ask?
I HAVE NO IDEA
I was just flashing things over trying to fix it and suddenly it went back to normal. I'm currently using a UV kernel, so maybe that's helping too.

Dont want to go too far OT, but how do you measure the battery current?
I assume you dont physically wire up an ammeter, or do you?
Ian P
Hahahahahaha, that's brilliant. I'm signaturing that
But no, I don't. The phone creates estimates of the present current/voltage loss, much the same way as it makes estimates of the battery % left.
So all you need is an app to log that! Currentwidget is the lightest, but I recommend battery monitor widget
OK its a battery monitoring app, but can you see the current drain whilst actually using other programmes?
Some apps use full screen so even the top status bar is not visible.

CurrentWidget, logging to file :

I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.
If your getting great battery life, help me and others by sharing your tips here.

Best tip is to stay on wifi as much as possible. I got 3 days on wifi and about 4 hours use.

I turn data off when im not using the internet and when I'm just listening to musc I just put my phone in airplane mode
Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too
get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.
I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.
I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.
I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off
So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...
Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).
Ok well let me just start off by saying. I LOVE this forum and the helpful and friendly people. Lemme give ya a run down on what I'm rockin' on this marvelous piece of technology.
Bootloader Unlocked - Check
Root - Check
R800x Timescape UK Firmware ROM - Check
V6 Supercharger - Check (Could use help making it start on boot.)
Better Battery Stats - Check (Could also use some more help since I'm a noob XD. More below!)
Battery Life - QUESTIONABLE
And here lies my problem here. Ever since I switched to the UK Firmware from Verizon's I've noticed the phones true potential and love the UK Firmware. However what is up with the terrible battery life? I've tried everything... It seems to DRAIN 1% every 5 minutes when I'm at school!!
BetterBatteryStats talks about wakelocks. I get this one sometimes called UID and have no idea what it is, and have looked for a solution but found never in ACTUAL terms I could understand. Also there's a blue bar and a red bar on the stats for those. Can someone please tell me the difference between them?
I've deleted Juice Defender as some people said it actually DRAINS your battery more. I've also heard this phone lasts sometimes 3-4 days on a FULL CHARGE?! I'd like that please! :O
Well when I'm at school I put my phones Brightness to 30%, Vibrate, and off WiFi.
I listen to Music and that seems to drain the battery ALOT more than I think it should.
Also, when playing Asphalt 6 HD, I was at 57% battery, I played for maybe under 10 minutes and had 44% LEFT!!! That's TERRIBLE!
Can someone please tell me how to make my battery last like others have it?
I also have 2X Battery installed but disabled and only showing my battery % on my taskbar up top.
Thanks again in advance for your answers and I hope I have provided enough info. THANKS!
If u don't use it during school then power it off. Also kill some tasks so your phone won't work hard and kill morw battery life.

I do use it during school. Sometimes as a Calculator, to text my family or if they have to call me in case of emergencies. I also game on it at lunch or listen to music when on a free period so...
And I do kill tasks all the time. It seems to just open themselves back up. Also I played Dead Space last night with 100% charge for maybe about an hour or 2 and the damn battery drained down to 55%!!!
I was on WiFi as well...

You honestly can't expect a game such as that to run on this phone and merely sip at the battery's juice. The percentage remaining when coming out of an intensive task, such as watching video or playing a game, isn't entirely accurate. Check the battery again after a few minutes of idle time, and it should be a little higher than it was before.
I use an app called Battery Defender. It's very easy to set up, and the main option is to kill the 3G data while the screen is off. You're still able to receive calls and texts and such, but the data is off, since you're not using it. That saves a lot of battery for me. You can also set it on a timed profile, where it shuts off all network connectivity during a set time.

Thanks I'll give that app a try.
Also I just feel I'm being mis-leaded by others then. Because I read on the android Forums people play games from 1-2 hours, stop, go to the store or mall for like 5 hours, come home, play again for another hour, and sleep and wake up with it at 7% charge or something.
Are you saying ti's normal for my battery to suck that much juice on Dead Space?
Dead Space is one of the most graphics intensive games you'll get to see in this phone. It's not Cut the Rope...
Well.. despite my other questions is anyone able to answer them..? ABout the battery stats app and such?
Also what would seem to be a normal rate of 1% battery loss? How many mins or hours do you think seems normal?

Did you wipe your battery stats before installing the rom? Let it drain to 0%, charge it without interruption? after that then you must let it drain fully and recharge too 100% without interruption again. This will "train" the battery. I have a battery calibration app if you'd like to use it
I would suggest you to do a fresh install. Wipe everything and start afresh. Don't restore anything and see what happens.

Did you wipe your battery stats before installing the rom? Let it drain to 0%, charge it without interruption? after that then you must let it drain fully and recharge too 100% without interruption again. This will "train" the battery. I have a battery calibration app if you'd like to use it

Yes I have done this. But ONCE. I haven't let it die again yet. Using Battery Defender is saving it's battery atm. Should I kill it again and let it do so?
Also for the Battery Calibration don't I have to do some weird thing with getting the phone to power on without the battery?

Thanks for your input, but I have too many things on my phone right now that I would lose. I wouldn't want to lose all my data.

Make a backup of all your data, then do a fresh install. The battery calibration app is simple, charge your phone to 100% and click calibrate. Then let it die to 0% and fully charge without any disruption..it's pretty simple

Must I make a fresh install or can I do it without a fresh install?
The battery calibration has nothing to do with a full wipe and reinstall. The fresh install is simply to fix problems that you are having, that no one else has, or doesn't have in such great force.
If you're worried about losing your data, get an app called Titanium Backup. It will allow you to backup your apps and app data to your sd card, then restore them at any time you deem necessary. There is a free version, but I would definitely recommend buying the unlock key. It makes your restores faster, and enables some specific functions that are locked out of the free version. This is my third Android phone, and the app has proven its usefulness time and time again, across each of them. It's the best way to port installed apps from phone to phone, as well.

Here's the thing. I have Titanium Backup. XD And also, I have done a Fresh Install before because I had this ROM then I switched to ICS Beta which was terrible so I fresh installed the UK Rom again and it didn't make a difference to when I had it before ICS BETA, so does that count? x.x

Is your battery life any different now than it was before the ICS beta?

Well...it seemed my battery life was better on the STOCK Verizon ROM but that ROM sucks for everything else..
So does anyone have the link to that battery calibrator app?
Leaving my OP in place, but I have rewritten the description with much more detail and pics here

I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?
might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

So I don't think I can blame it on that.
Do you have any exchange sync on your phone?

can you give us screen shots of battery stats?

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)

System panel paid version with monitoring enabled is the best for tracking apps using CPU.
OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??
Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.
1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.
I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.
You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

when i did a complete quote and re flash i did not setup the exchange account, but the issue continued.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.
