[Q] HTC Kaiser CPU Doesn't Sleep? - Tilt, TyTN II, MDA Vario III Android Development

Did a search, and didn't find anything regarding this, so I'll point this out. I've noticed whenever my Kaiser (KAIS100) goes to sleep, it doesn't actually sleep, I can still press every button and the phone will "wake", screen comes on.
When I check Spare Parts > Battery History, it shows my phone's been running for 5days even though it's been on for 10 minutes actual. If I continue to put the phone to sleep that time grows exponentially.
Is my KAIS really sleeping, or is there a bug somewhere?
I'm running l1q1d's latest .32 kernel, with Fat Free Froyo build with system/data on NAND.
Battery also only lasts about 8hrs in "standby", and not even 2hrs with full use. With WinMo, I get about 36hrs standby, and about 5hrs full use.

I guess its not completley implemented yet, search this forum I remember I looked something about it, or post a comment to our good friend n2rjt in that thread:

Have you modified .nbh file with atools and entered the correct value on the advanced batt capacity? (units = battery real mAh * 1.6) if you havent or if you own an old battery you'll experience a lot of batt consumption or inaccurate readings....

The phone locks like it's suppose too, but the problem I'm having is the CPU of the Kaiser isn't actually falling asleep. I'm getting the same battery consumption as when the screen is off compared to on, and sitting there (no activity on my part, just leaving the screen on for no reason )
Every so often the phone will be asleep, and the only way to bring it back on is by hitting the power button, but about 95% of the time I can press the call button, end button, OK button, IE button, hell even push down on the wheel on the other side of the Kaiser and the screen will come on showing the lock screen.
As far as the battery capacity, I have not done that, but the phone's been auto-learning my capacity, and it will get to the 2160 units, compared to the 2000 it's always set too, and sometimes reach 2377 units.
I have tried several Radio versions, down to 1.65.xx.xx version (which was the original version on my phone), and no changes, and tried different builds and no change either. DZOs kernel doesn't make a difference either, except screw up my battery meter completely. lol

uhm thats wierd.. i can only unlock through the power button, what i have experienced is that if its conected to an external power source it does reacts to any button I press.... but not on battery... maybe its a build issue... right now im using scoots CM rls 5a, dont remember if warbyte's donut behave like that...

Did some more testing, and found that without it plugged into power it does only respond to the power button, but again it's only about 15-20% of the time, and even those times seem iffy as it just seems like the phone's just slow to respond.
Phone is also somewhat warm as well even when "off", and I do have the phone overclocked to 450MHz, kernel is set to 425 (running a test on speed/stability atm)
At 425MHz it's still reasonably warm, and at 450 the temperature jumps alot.
Anyone else have an issue of the tap sounds when tapping on the screen sometimes not playing? Granted phone quality is great, and GPS is working well, though Camera is broken on my end, even though it was working before.

It sounds like there is a real issue. Some application is running continuously for you, preventing the CPU from going to sleep. I have had that before. Try removing widgets from the main screen. For me, the problem was an app that showed a flip-clock and the weather, and looked just like HTC Sense. I don't remember its name but it used to be popular.
The newest 2.6.32 kernel seems to sleep relatively well for me. Sometimes it wakes on any key, and sometimes it wakes up to a totally white screen. Other times it just plain refuses to wake up. Usually I can coax it back to sanity (from white screen or from sleep) by Fn-Left keyboard softkey, then Fn-Right keyboard softkey.
Your phone should get approx 10 or so hours of life from a charged battery. Less than you get with WinMo, but lots more than you seem to be seeing.

Ok, I'll give it a whirl, and remove some of the widgets I have running, and see if it does help out. Right now though I'm re-installing /system as I tried messing around with the density as 110 seems to work real well with where things are placed on the home screen (no widgets are overlapping each other), but Market won't work, and the Android Keyboard keeps crashing (on-screen).
But anyways, phone's booting back up, so I'll test out the battery life here again, as I got about 95% charge right now, so should serve as a good test for battery life, and CPU Sleepage.

Having a similar issue, seems to behave ok (screen lock comes on when I press power button) but power usage on standby is similar to original poster's. About 8 hours standby. Went to bed last night and it said 66% charged (1300mAH battery) and it didn't last the night. Takes a looooong time to charge to full though so I doubt it's lying about fully charging the battery, suggesting it's using it up at a fast rate.
How do I check background tasks?
Edit: This is with WiFi, GPS and Sync OFF by the way. On the other hand I live in a low signal area (typically 1-2 bars) could it be straining to get a better signal? Used to have an old nokia that used to run itself flat in no time when there was a low/missing signal!
Edit 2 : Figured it out, turns out the ebay app has a service and a process running - even with notifications turned off! Have killed these and see if anything improves

That could very well be part of the problem, although it shouldn't kill it from 66% with just the radio. How much capacity does it calibrate itself to?

Phone Radio really shouldn't use more power with low signal, in fact it really shouldn't affect power output at all (well except the fact that it's on). I have a 1350mAH battery, but it's reading at 2470 adjusted, so I re-flashed a new kernel with the new battery changes, now it's reading 2437units adjusted, which is over 1500mAH for the battery which is not what I own. But on the bright side, my battery capabilities are improving, and the battery meter is starting to read alittle more accurately.

yes, i boutght seidio 1600 mAh, and the kernel ended up adjusting it to 3260 units... (about 2000 mAh) maybe the 1.6 factor isnt right just as n2rjt said, maybe its closer to the 2.0

Seems like ebay may have been the culprit. Killed the ebay process and application in the background and only used about 10% over night (as opposed to over 60% the night before). I'll have to leave it overnight with ebay running again for a proper scientific test next

Yah, I'm starting to run into issues with certain apps keeping the phone awake and not letting it sleep. I kill some of the apps and it actually helps out the battery some.
I installed the original launcher from one of the other froyo builds, but came across with an FC with acore, so now back with ADW.Launcher or LauncherPro.

When you install a app, take a look at its requirements, like "PREVENT FROM SLEEP". You might have a app doing just that..

Yep, most of the apps I download have that. But in sad news, I'm actually going back to WMO 6.5 as I can't seem to keep Android stable on my kaiser.. I've reinstall the same build twice (which I know is not corrupted, as it was working fine 2 days ago), and Market is always corrupted...... So, for now, until I have a secondary phone I can revert too, I'll be going back to WMO for the time being.

battery drain tips?

When I run the latest android build on my Tilt 2, it flies through battery like no other.
Are there any settings I can tweak to get at least a full day's worth of use out of it (mostly in standby anyways)?
Thanks
Regards
Smith
I'd love to hear anyone's tips as well. As mentioned here:
http://forum.xda-developers.com/showpost.php?p=7959929&postcount=7622
Setting the sleep mode = 1 doesn't seem to work for me. The processor seemingly goes to sleep and enters a coma (yes, I set the clock speed back to stock in the startup.txt).
One quick tip to the OP is set the clock speed to stock.
Edit: sleep mode = 0 seems to work (GSM phone here). However, deleting the "acpuclock.oc_freq_khz=XXX" line from the startup.txt and setting sleep=1 just might work as well.
Edit2: sleep mode = 0 seems to result in the phone functionality breaking. It stopped waking up to phone calls after a while, and calling out wouldn't work either. Damn.. Just a heads up.
1. Close every program that you don't use on startup of android. You can do this with advanced task killer.
2. Run stock speeds.
3. Turn down the screen brightness.
4. Make sure your phone goes to sleep when you are not using it (green led = sleep)
Is advanced task killer installed by default?
Also, how can I clock it to stock? I wasn't aware that it was overclocked past stock.
Screen brightness makes sense, I'll definitely do that.
So, if green is sleep, what is the orange?
Thanks
Smith
I reckon hepatic feedback would drain a little battery on its own probably best to turn that off
This is all true. I'll have to do that.
Still figuring it all out. Once I can get a solid 18-24 hour charge cycle out of it, Android will become my primary OS, easily. Simply works better, IMO
For me sometimes it's green, sometimes it's Orange - not sure how to change it back green -
I use Advance Task Killer, but then i also read that Froyo 2.2 doesn't need a task killer?
The two things that have helped battery life the most were:
-Switching to stock clock speed (the reference over the overclocked BLZN which i loved but killed the battery life)
-turning off background processes... i only turn it on when i have to (using the market, etc)
I would love to hear more tips
The colours are not that hard.
Red/orange = awake
Green = sleeping
If the LED stays red, then your device is doing something, you can either wait or try closing the programs with the task killer. That will help sometimes.
For returning to stock speeds read the faq And advanced task killer can be downloaded in the market.
Thank you guys all so much, big, big help to me!
Android is definitely going to be my full time OS shortly
Smith
Its kind of tough trying to go anywhere without a charger nearby. The battery drains quickly and on top of that the actual battery meter is off.
So sometimes that is a main issue

Indeed but that is something that they are working on it as we speak. Give them time
I ran a test last night before going to sleep to see how long the phone lasts.
Charged my phone fully. Ran advanced task killer and killed all the programs. Put the phone in deep sleep ( green light).
Woke up 7 hours later and phone was completely dead. I do have auto sync turned on, but only over wifi, so it should not have used any data as i have the data turned off and no widgets on my home screens that auto-update.
I'll try again tonight for a shorter time (5 hours).
Running the blazn aug 30th build.

How did you 'put the phone in a deep sleep'
I turned off all auto updates.
The next day i did the test again, charged the phone to 100% and used the phone moderately for 8 hours before the battery died.
Without overclocking i can safely say i can get the phone to last 8 hours with moderate to heavy usage, which is excellent.
My main problem with the new updates are that it constantly restarts or crashes after using it for less than 30 minutes while before I could use it for several hours. Not sure whether it's to do with battery life or not as when it boots back in WM the battery is near full.
The biggest things that have helped conserve battery life for me are disabling GPS and background syncing but some apps require this to be enabled. :S
Phone seems to recover from "sleep"
FWIW, I set sleep mode = 1 and removed the overclock line from the startup.txt and the phone SEEMS to sleep and "wake up" just fine. Previously, I had problems with the phone going to sleep and when waking up, everything seemed fine, but the phone didn't work. With the overclock line removed, it seems to "wake up" with the phone working now.
Just a heads up to anyone who wants to save battery life.. might want to remove the overclocking line in the startup.txt..

[Q] Questions about CyanogenMod, and general battery life

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 =/

[Q] Cell Standby/Phone Idle battery woes

The battery on my Evo has been plummeting recently. A while ago I could make 36 hours easy, and now I am lucky to get 12. The reason it seems is cell standby/phone idle, according to battery info. Over the course of last night I went from 85% to 28% while I just slept, and according to battery info these two things are responsible for that.
I'm not sure what they are or how to decrease, however. I read that NV and PRI 1.90 was causing problems for a lot of people so I tried downgrading to 1.77 as suggested, but I have no idea where to find the information to see if I successfully downgraded. I am running CM7 nightly build 23, I have wiped battery stats once and I am currently waiting for the phone to die before charging it again, but this has been going on for quite a few days over numerous roms and battery wipes. If I put my phone into airplane mode, the battery is hardly touched overnight. During the day I need my phone on however and the battery drains just as fast, whether I am using it or not.
Any suggestions?
ps. under accounts and sync the only thing I have set to sync is email by push, I receive only a few emails a day and a couple at night so I don't think that would be the problem. Facebook is also set to sync contacts, but only find status updates and the like when I refresh manually. Twitter, and my google account in there but both of those are set to sync manually.

I have never used spare parts in my life so bear with me; but when opening it now all I see is device info including battery history, battery info and usage stats, and general options which all have to do with animations, font size, haptic feedback, or compatability mode. I don't see anything that talks about wake lock in here
You click battery history, then on the first tab, click partial wake lock, and on the second, you can click since last boot.

thanks! under partial wake usage since last boot, it's hardly nothing.
Android system is by far the winner with almost 11 minutes of usage, email is next at just under 2 minutes, facebook at about 1.5 minutes, and a couple other things (dialer, sms, google voice, google services) all coming in between 5 and 30 seconds.
Hmm...are you in a bad signal area or leave your radios [3G,wifi, 4G] on all the time?
I suppose I have 3g on. I never leave wifi or 4g on and my signal is between -85 and-96, according to battery info my time without signal is 0%
Well you should turn your 3G off when not using it, that'll definitely save your battery.
I will try that in the future, but it still does not explain why I am getting 1/3 the battery life I used to while doing much more to conserve battery. Could it have to do with my pri and prl and such? Maybe I need to update profile and such, like it's not looking for the right towers? I don't know much of anything about how polling and service works.
What's your wake time vs. your up time?
It sounds like you have something staying awake.
Have you gone to menu>setting>About Phone>software information to see if your PRI version & NV have been downgraded?
What kernel are you using?
Are you using RA or Clockmod for recovery?

I'm not sure how to check wake time vs up time, but it would likely be useless right now, as I nandroid backup, flashed a sense rom, updated my prl and profile, checked to make sure i did downgrade pri/nv and then went back to cm7, so any battery info it is going to give me right now will be inaccurate while I wait for it to charge/discharge again over the course of the night. It does still have my previous information though since it was a nandroid backup and I've had it plugged in entirely since then.
I did succesfully downgrade to 1.77 PRI
kernel is savagedzen 0.2.1 cfs havs wimax GB (2.6.37.4)
RA for recovery.
I also uninstalled a few programs including facebook and twitter in case there was anything like that interfering with my services. I still use Go contacts and Go sms however, but I have unchecked any options with them to have facebook integration. If you could tell me how to check up/wake I can check that tomorrow morning when I wake up to see and go against whatever I had. Currently I'm just trying a few things out before tonight to see if anything had helped. An idle phone sitting on my window sill for 8 hours should not drain the battery THAT much, so something is off.
Go back into men>settings>about phone>battery (you can check it now)
If your up time and awake time are the same, you have a program that's stuck in wake. I also use a program called "system panel" that will show me live time which programs are using the most resources. OR you can use "Battery Monitor".
If you have wifi at home I would suggest you set up your phone to connect to wifi and shut your 3g off. I use a program called "Y5-battery saver". It automatically connects me to wifi at home and disconnects and switches to 3g when I'm away from the house.
attached is a screen grab of the graph from battery info
if needed:
cell standby says time on 15h 44m 47s (same as time listed on battery)
phone idle says 14h 46m 58s
(these 2 items used 47% and 44% respectively
thanks for the wifi tip, i used it on sense a lot but with most aosp roms it causes problems unless you set it to never sleep, and i didnt know what that affect it had on battery so i usually just turned it on when necessary or when in a low-signal area like school.
That doesn't seem that bad for ~14hrs on battery.
my problem is that it's while I'm sleeping. I used to get 36 hours of battery before getting to 15% and being told to plug in, and now I used it a little last night, went to bed and woke up to it being at 28% and was told soon after to plug it in. I just dont remember sleeping destroying battery life like that in the past. granted 15 hours isnt that bad, but when 10 of the 15 hours the phone is just sitting there it worries me because if I were to go through a normal day, where I charge it at night and use it during the day, there is just about 0% chance that I'll be able to make it through the day without plugging it in sometime in the middle.

yeah, that's not bad. You're still at 87%? LOL. Maybe I need to switch to AOSP ROM!
I'm Back to 87%, I've been on the charger all day, hence the battery graph raise. the dramatic raise was from when I flashed the sense rom to update my profile/prl. (obviously it wasn't monitoring during that time and when i came back and started monitoring again the battery was much higher)
it actually died after ~15 hours, with 10 of those 15 hours having doing nothing. I got systempanel to see if it gives me any more info and the main reason i use aosp is because of the terrific backlight handling. I like it to be super dim while inside and bright outside, and find on sense roms the auto backlight is too bright under normal conditions. I should be getting much better battery life than this. I'll try again tonight with the battery being monitored to see whats up and I'll try going into airplane mode tomorrow to see what that does at night for comparisons sake. hopefully there is just some program using lots of data that I don't know about. i'd love a quick fix lol
It's almost as if there's an Evo "battery curse"!!!!!! It has been HELL finding a ROM that I love that has great battery life. I really liked Myn's but for some reason I could NEVER find a kernel that would give me great battery life. I'm currently using ultrablakk 3 by King's and love the interface, just trying to find the right kernel myself. I think I'll do a nand and try an AOSP for a change. Vaelpak looks stable. Good luck with the battery life issues!
I'm using an unrevoked-rooted evo and at 10% wake time, it lasts for about 15 hours unplugged. That is why I usually keep it plugged in whenever possible. I have task killer and do not synch anything except for weather and news. I do have 3G running all the time as well. I wouldn't do that if it weren't for the email checks (4 accounts checking every 30 min). If the 3G could be automated to turn on during the checks, that would save more battery life, but I don't know of anything to do that yet.

[Q] 100% full charge to 0% in 6 hours??

I charged my Nexus LTE(unrooted,4 days old) till it was 100% before I went to bed. As soon as I set my alarm I unplugged it to test to idle. Well I just woke up 6 hours later and it was completly dead. I have it on the charger now, I hope i can see the spycpu cause that was main purpose for leaving it off. I do not sleep surf either.
Is this a defective phone?
Wow that's nuts. I definitely never get that sort of battery drain. Are you rooted? Using a custom rom or just stock?

I have to leave for work now with out a phone, I will try to check up via computer (feeling like a dinosaur).
Ha ha I know I feel so bad when I don't have my phone. Maybe see if it happens again tonight. If it does I would get on to the carrier. Have a good day at work!

Are you sure it was dead or you just had a sleep of death? If it truly was dead you definitely have something draining your battery during idle. I highly recommend you turn off your LTE antenna if you haven't already unless your using data intensive apps and you need it, such as surfing or netflix or something. Also, change your sync times to less often, I do every 15min. Sign out of google talk, use wifi when you can, adjust screen brightness, disable bluetooth. White backgrounds will eat your battery faster as well. What else am i forgetting.... Root will help if you can manage to, its incredibly easy especially with the new rootkit out, because you can load francos newest build which has increased my battery 2x, with 25% drain in the last 8.5 hours even with a 1/2 hr of whale tail last night. Also make sure your not running something stupid in your background thats eating your battery like a task killer or battery spy or something, those just rape your battery
If you turn on Google+ instant upload and it has thousands of pictures to upload that will kill your battery in a few hours. If your phone is staying awake because of Android OS then try turning off your GPS.

As noted in a lot threads on a lot of forums, there are some phones that have a problem with the Android OS and the "Keep Awake" time. There seems to be an issue with some phones not truly going to sleep when the power button is used to turn off the screen as opposed to letting the screen turn off automatically when the screen times out. This results in a very high time in the Settings/Battery/Android OS/Keep Awake menu.
In stock form and with every rom that I have installed, my "Keep Awake" time was always about 50-60% of my total battery time. If the phone had been off charger for 8 hours, I'd have 4-6 hours of Andorid OS "Keep Awake" time. This was true even if the phone had been in my pocket unused and seems to be exacerbated by my habit of turning the screen off manually with the power button every single time. I used to never let the screen timeout.
There seems to be two "fixes" according to Franco (of kernel fame). One concerns the camera. Seems the camera is started and then turned off during startup. But in so doing, it leaves a sensor active and this prevents the phone from actually going to sleep. So he recommends starting and using the back button to go back to the home screen. The other is DRM Protected Content. He recommends this be disabled or frozen. A third, that I don't believe I recall seeing him recommend but that I have seen on his thread at XDA (down for blackout right now) is to disable Maps.
I have done all three of those and my Keep Awake time has gone from 40-50% of my total battery time down to a few percentage points. I mean if I don't use my phone it will now show less than a minute of Keep Awake time per hour.
Good luck 
My VZW nexus can idle with moderate use on constant LTE and get 15 hours with out issue. Hell I have even gotten more so check google+ as suggested. If it went dead on idle with nothing running constantly to cause it than I would say your phone and/or battery is defective

Ive been getting good battery life, despite my awake time being around 6-8 hours at the end of a charge. I tried the camera close but that never helped, I've just disabled DRM though. Also, GPS locator has been associated with this, which is probably what you meant by "maps". I just turn off my location unless i need it for navigation in location settings
how do you disable drm? and what exactly is it?

It has to do with digitally protected files, music, etc. One time I went home screen/menu/settings/apps/all/drm/disable. The last time I did it from Titanium and pressed the freeze button for that app.
Good luck.
BTW, both actions can be reversed.

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
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.

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.)
Sent from my jitterbug using tapatalk.
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

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.

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.
