The last couple of days my battery has been draining ridiculously fast. It just went from 50% to 8%, just sitting in my pocket without otherwise being used, in the last 3 hours. Here's what the battery usage displays:
while unplugged for 3h 3m 24s:
Android OS 81%
Cell standby 10%
Phone idle 4%
Display 3%
Android System 2%
Obviously something is going on with Android OS and I suspect something I've installed is doing this. I have Watchdog installed but it hasn't given me any warnings. Is there some way to determine exactly what is causing the battery drain, other than removing apps one by one?
Thanks!
I've suspected that my display keeps coming on when my phone is in my pocket.
Both the power button, and the trackpad turn on the backlight for 15 seconds when pushed, and it's very easy to do both when the phone is in your pocket.
I stopped using the HTC weather app, there is no way to stop it from constantly searching your location and it kills the battery FAST if you are on the move. Since I stopped using it I have seen 10+ hours of battery life a day and I use it hard, internet, gps, music, twitter.
It's the suspend process.
I can't link it to you cause I'm on the phone but if you look around, you'll be able to find it.

I don't think it's the display because the battery usage isn't showing the display as the main battery usage (unless I'm really using it for a long time). It's definitely something belonging to "Android OS". I wish there was a way to determine specifically what process within "android OS" is to blame. I really don't know much about Android or Linux in general so "android OS" is mostly a mystery to me.
I did uninstall several programs yesterday night and was almost convinced it was behaving better but it looks like after the first hour that Android OS is creeping up and overtaking the battery usage and the battery is draining pretty fast despite not using the phone other than to occasionally check the battery usage. At the current rate I'd be lucky if the phone isn't dead before the end of my workday. It probably doesn't help that I have a rather weak signal at work but if it was increased power to the cellular radio that was the culprit, would it show up under "Android OS" or "Cell standby"? I'd suspect the latter, but maybe Android isn't so logical in how it groups processes....
I'll try removing the HTC weather widgets as suggested and look up the sleep process.
Thanks!
It is the "suspend process" like that other poster said. Here is the defect, you can read through if you like. It's a known problem and not only isolated to mt4g
http://code.google.com/p/android/issues/detail?id=11126
How did people determine it's the "suspend" process? I can't seem to find any way to determine what processes are specifically involved. Is there an app that will tell you that? I am running Watchdog Lite set to alert me at 50% cpu and have never got an alert which makes me question whether my issue is the same one described in that thread. Various people were describing 100% cpu activity by the suspend process and it doesn't seem to be the case with me.
I did have 2 weather widgets on my home screen. I deleted both and since then the problem appears to have gone away. I'll have to wait a while to see if it's truly fixed or just a coincidence. Someone in the suspend thread did mention that plugging into a charger temporarily fixed the issue and I did charge the phone for a while after deleting the widgets so I'm not convinced just yet.
One thing I did notice in the battery usage is that google maps seems to have a significant presence, despite the fact that I haven't used maps at all since last unplugging the phone. What is maps doing in the background? I wonder if it's trying to determine my location and cache map data...
Thanks!
Install Watchdog and in its settings, include, monitor, and display all phone processes.

Enable system process and set thrashold to 30% and you will see the suspend process. Or when you notice the drain is happening go to the phone hidden menu. You know the #*#*3626*#*# in the dialer and then from there go to battery usage then select CPU usage, you will see the suspend process on the top or near the top.
Just use some memory management apps. I currently use ES task manager and in advanced settings, i set it to kill all processes when i power down screen. I never use any battery when phone is unplugged(i literally left my phone unplugged overnight midnight to about 7am and it stood at 73% entire time). And having it rooted, i use SetCPU and set the phone at around 768mhz powersave when i'm not messing with the phone heavily. I easily can squeeze about a day and a half out of the battery.

sorry, that was not the correct sequence at all. I was trying to do it by memory. It is *#*#4636#*#* then select battery history, in the first dropdown box select cpu usage. That menu is pretty useful for other things to like network usage breakdown per app, gps usage, etc.

Since removing the HTC weather widget my battery drain issue has completely disappeared. The battery now lasts a reasonable amount of time.

Actually I have removed the HTC weather widget couple of days ago and also disabled the water sync in account settings too. That seems to have help with the suspend process on my phone also.

What's the "water" sync? Is that a swype typo for "weather" sync? (Swype errors are annoying in that their usually not so obvious.)
I had also disabled the weather sync (forgot to mention it). Seems to be a lot of little bugs in Sense that need to get fixed.
Why don't you guys do what I did... I have profiles set on setCPU so that when the screen is off the phone runs at 368mhz max and the when the screen is on it'll go up to opp speed... That actually saves alot of battery for me.
Sent from my HTC Glacier using XDA App
Sorry it is weather sync. Yeah keyboard error. I stopped using swype recently for this very reason, but touch input isnt perfect either but still much better for me.
Ya if you are using OC based kernel then use SetCPU to scale your mCPU. Set few profiles for example my max is 1.7ghz, avg is 1.2ghz, min is 768mhz, idle is 368mhz.

Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.
Thanks, good article.
Very detailed and useful

Could you make a list of the bloatware that can be safely removed?
I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...
Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.
This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.
Excelent article and good quality info. Thanks and best regards!
awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.

Hi,
In my little experience, there is no software that makes alot of diference, normaly what i do is:
disable motion
insert *#9900# and disable Fast dormacy - check is your network needs this
disable sync for accounts
disable GPS
disable wifi gps
disable wifi when not using
set brightness level to auto
set wifi sleep policy to when pluged in
Of course there are a couple more things you could do, and again this is what i do cant say it will work as good for you.
rooting.
Tasker
With it one can automate almost everything on the phone.
It's almost like programming i use it all the time and there are a lot of examples on this forum. http://forum.xda-developers.com/showthread.php?t=1110775
Juice Defender Ultimate + Battery Saver Pro (by Antutu).
I tryed a few battery saver apps but no longer use them as i found if i turn auto sync off, change wifi sleep policy to never, untick network notification, and use task manger frequently to kill unused apps my battery lasts a lot longer. I also use easy task killer and set it to kill all apps every 30 mins. im using king cobra v1.1 for evo 3d gsm and the battery life is amazing!! just swapping battery's over now and its nearly 9pm!!
If any one needs any help rooting or unrooting the evo 3d gsm hboot 1.4.9.0018 let me know as i have done it a few times now. I unrooted my phone back to ***locked*** s-on with no traces of rooting, then checked for ota updates, wouldnt of installed them tho even if there was one!! then downgraded back too 1.4.9.0007 and rooted it again with revolutionary.

forgot to mention auto brightness is a must. and i also calibrate battery after installing roms . can anyone please tell me if calibrating the battery every time it gets to 100% is good or bad? thanks.
When you use an xperia mini pro like me, with just 970 mAh, you get to try all possible battery savers... and unfortunetly no one of them makes the exception... actually as said evilchild, they don't make difference...
just disable everything that may drain your battery, your launcher effects too can be in cause, get rid of unuseful apps, put your brightness to lowest levels or just get it to auto if your rom use it... choose the best profile for your CPU... and with this you are good for 10 new hours in your daily battery life.
I'm not sure a 'battery-saving' app is real.
They just disable some features that we can manually do that. They just make it automatically disabled.
But, 2x Battery is good. It could disable Wifi or mobile data while the display is off.
one touch battery saver is awesome. create a widget to enable/disable wifi,gps,sync,brightness,bt,data ect with one touch!. free on google play

From the apps I tried out and used, almost all of them just disabled certain things, or tweaked settings that I could have done on my own, and eventually did do.
I found it easier to just go on a sub forum for the phone I had at the time and look up tweaks, tips etc.. I'd say doing this helped me more than any app I found previously, and was easy to do.
Dolphin companion is good and gives more remaining of time.
I use juice defender and the setting: "Only 2G"
3G takes a lot of battery..

None. There are no working saving battery apps, not a single one.
What a battery saving application can do is to change the phone configuration to a lower energy one, just like lowing brightness, disabling data packages and such, to sum up, things you can do by yourself and you'll save the battery that that application consumes.
The best way to save battery is to make a proper use of your phone:
-Disable gps when you don't need it.
-Turn off bluetooth when not needed.
-Keep screen brightness low at all time.
-Disable data packages before going to sleep and enable them again when you wake up.
-Keep your phone clean by periodically uninstalling apps that you don't use anymore and that make unnecesary use of memory, cpu and battery energy.
-Check your battery use statistics and keep an eye on applications that are using energy unefficiently, and replace them with better alternatives. Facebook and facebook messenger are clear examples.
-Some people say that connecting to 2G networks instead of 3G helps as well.
-Activate wifi at home, it seems to eat less battery than connected to 3G.
There are more tips out there, just gogle it and make a responsible use of your phone. Keeping phone clean and lowing brightness will probably make the biggest difference.
Moreover, if android S.O. is on the top of the list of battery use, your phone's software entered a weird condition. Reboot it and if it persist, consider a factory reset.
I hope this helps
I just started evaluating Juice Defender Ultimate to see if it can save battery life, but there are many options that I don't fully understand. I have attached a screenshot of the Notificatin pulldown window from my Galaxy Nexus which shows the JD status. There are 9 objects just to the right of the JD shield. They include 3 icons, 3 colored circles and 3 lines of text. Can anyone explain what each of them mean? I have checked the JD online info, without luck.
My best guess is:
the up/down icon represents mobile data
the red circle next to the up/down icon means mobile data is disabled
the radiation icon represents WiFi
the green circle next to the radiation icon means WiFi is enabled
the 3G icon represents 3g mode
the red circle next to the 3g icon means 3g is disabled and 2g is enabled
As mentioned, these are just my best guesses. I have no idea what the 3 lines of text mean?

I know I've made a few posts about this in the past, but now I've learned a few things since then.
I know the battery isn't the greatest on the infuse (no rom that I'm using atm..) but would like to get the most juice out of my device that I can. I have root access and currently use the apps "battery calibration" and "no-frills CPU control" which I set my cpu at a relatively low frequency to help keep juice.
My phone is drained throughout my day, even without use. I believe it primarily happens because my data (mobile network) consumes it. I know apps such as "juice defender" are great at reducing idle drainage because it shuts off your network connection while in idle to save battery. However, I have used this application in the past and after a few days of use, it shuts off my mobile connection altogether.
My question is, if I were to use this application again and my mobile network were to malfunction, would I be able to change my apn to regain my network connection? In the past I had to reset my phone to regain connection, which isn't really worth using if that's the only solution.
Or are there any other battery saver apps worth using??
Thanks

A bit more information is needed before a specific course of action can be recommended. How much battery life are you using in an average 24 hour period? Also, what version of Juice Defender(beta, free, plus, ultimate) are you using, and what specific settings are you utilizing. It is a very customizable program after all. You might look into Battery Indicator Pro, which estimates your total remaining battery life based on your level of usage. I would also recommend CPU spy, which, if your device is rooted, will show the percentages that your device is running at various CPU levels.
If you turn off all the locational stuff, turn off 'update my current location' in Navigator, and set your CPU gov to conservative, you might get better battery life. I've not had any lasting luck with any of the battery saving apps. In the end, I decided to buy a couple of Anker batteries from Amazon just in case I have a bad battery day... Also some of the battery saving mods work, but I'm not sure about applying them to ICS and JB ROMS. I haven't tried!
Battery life is what you make of it..
Anything running in the background will drain the battery.. email constantly checking for new messages, twitter, Facebook, GPS, WiFi if no connection is found, etc..
Anything that makes the phone process even while the screen is off is going to kill a battery..
What ROM are you using? Some ROMs have better life than others..
How much are you actually using the phone?
What's the brightness set at?
Have you tried changing the processor and slowed it down?
Lots of information that is missing is helpful..

How about putting a widget on your homescreen to toggle data on/off. Keep it on only when you need it. I go a step further, I use Tasker to automatically turn my data off every time my screen times out (because that means I’m not using it... I can restart my data later with my widget when I need it). Maybe that’s extreme, but I’m not just watching my battery.. I’m managing my limited data plan.

It may be that you have wakelocks keeping your phone awake when it’s supposed to sleep. One way to see this is (in GB or above) Settings / About-Phone / Battery Use...then click on the small graph at the top... should expand it to a large graph with traces along the bottom including Awake and Screen On. If you have long periods of time where phone is awake while screen is off, that’s a wakelock problem. A good program to troubleshoot that is Better Battery Stats. If nothing else, follow the instructions in the first post in the BBS thread linked below, and then post a dump to the end of that BBS thread (the developer and a lot of other knowledgeable people follow that thread and will help you interpret results):
http://forum.xda-developers.com/showthread.php?t=1179809
Thru use of BBS, I found that Google Maps is one that was keeping mine awake and I think someone else on the forum reported the same. If that program (Maps) is causing problems, you can disable it from auto-starting on boot using Gemini Manager. It will still be available when you need it, just take a few seconds longer to load the first time after boot. Then need to reboot to stop it from causing wakelocks after use (there may be other easier ways, but this works for me).
Another program (Power Tutor) was helpful to me to see programs that were consuming unusual amount of battery although not necessarily thru wakelocks. In my case Dolphin Browser HD was occasionally drawing very high power even when that program was not actively in use.

Then need to reboot to stop it from causing wakelocks after use (there may be other easier ways, but this works for me).
Another program (Power Tutor) was helpful to me to see programs that were consuming unusual amount of battery although not necessarily thru wakelocks. In my case Dolphin Browser HD was occasionally drawing very high power even when that program was not actively in use.

So how can I stop maps to running in background? only rebooting the device is the only option?or is there any other option?
TIA

Just to provide more details on my previous post (not sure if it's answering your question):
I followed instructions here:
http://forum.xda-developers.com/showpost.php?p=29420959&postcount=7059
In particular, I installed the free program "Gemini Apps Manager". That allows you to stop programs from auto-loading at boot.
So I used the program to stopp Google Maps from auto-loading at boot.
That stopped a large chunk of my wakelocks, as long as I don't manually launch Google Maps.
If I do manually Google Maps, then those wakelocks come back, and to get rid of them I have to reboot.
I don't use Maps that often (only when I go on trips), so it's not a big problem for me to reboot when I'm finished with my trip to help keep my battery use low.
It may also be possible to kill it from the list of applications at Settings/Applications/ManageApplications and killing botht the application and the process...but I'm not sure if it will stay killed that way... haven't tried. I know some applications have hooks that make it hard to get rid of them once they're launched.
But (if you haven't already), I think it's a good idea to use BBS to find out what programs are causing problems on your phone. You may have other apps causing lot bigger problems than Maps. And it certainly may be the case that a program that acts up on one phone can be fine on another phone due to differences in the way the user configures the application settings and the phone settings (along with other possible differences in application version, ROM used, etc etc).

Thanks for your detail explanation. My main question was how can close the app without restarting? i feel my major battery drain is from dolphin browser, befor dolphin i used opera, even that has the same problem. Most of the time, if I dont open dolphin, my phone battery is good, but once I open it, it drains battery. So i am looking for soemthing simple which does, without rebooting the device.
Any way thanks for your help.
hi, i have an htc sensation 4g running cm10 jelly bean rom and i wanna know how to put my phone on deep sleep. im on bruce kernel 3.0.49. can some1 please help?
I believe the device should automatically go into sleep mode when not in use. I don't believe you have to do anything for this to occur. Make sure none of your applications are running on there own.go to settings, apps, running apps and see what's running. Leave system apps alone however if other than system apps are running you can close these apps. Just press on the app and a menu will pop up. The running apps other than system apps could prevent deep sleep. Make sure you don't shut down ANY system applications that are running. Those should be fine. Hope this helps. Best wishes.

If you're a little adventurous you can check out the Q&A thread about Bruce's ROM. Skipjacks and Tobitge have put together a list of processes to kill using system tuner (I think). The wakelocks are a known issue and perplexing to say the least. I am beginning to wonder however how big of battery drain they really are... I'm having pretty good results despite them.

does it improve battery life tho?
Yes it would if they could improve the wake lock situation. Check out as above thread suggested, they possibly know of a fix! Also have you considered a extended battery? Extended battery really helped my battery issues. But in this case it sounds like a known issue with something in the rom causing wake lock
This is where your drain is coming from. Check out the fix above. See if it helps.

This only helps with some specific Google Services wakelocks. The Android framework is causing some other wakelocks through the AlarmManager service (Not the same as the alarm clock). These wakelocks have proved very elusive to destroy.
The modifications to the google services framework that Tobitege and I worked out do seem to have some impact on battery life. But if you are a big user of Google Now or GTalk, these modifications are not for you as they break both of those services (mainly because those 2 services were 2 of the 3 main causes of Google wakelocks)
The thing with the battery drain because of these wakelocks is that they drain the battery during sleep, but that drain isn't being properly reported in the battery stats (this is an electrical physics problem related to how a slowly discharging power cell can give a false reading of voltage, not a software problem). So you'll have the phone in sleep for 3-4 hours and it will show no discharge despite constant wakelocks. But us the phone for 10 minutes and the battery quickly drops 15%. In reality it drained that 15% during sleep due to the wakelocks. The battery stats just weren't showing it right away.
Bruce did make some tweaks on 10/27 that have improved the Android inspired wakelocks noticably. But they are still there.
