I picked up betterbatterstats as my battery life has been crappy over the past few days, I have found the following to be true: I am barely using the phone as I'm at work all day and the battery is draining much faster than before. My screen time is 20 minutes total for the following stats.

I'm not sure if I'm not using BetterBattery correctly but I can't find an option to tell me what offending processes are keeping the phone awake for so long. How do I figure out what is causing this?
Thanks for any help.
Check partial wakelocks in better battery stats.
Turn off your GPS. That is what worked for me. I have 9h 6m 20s on battery and Android OS only has 51m of awake time.
check your apps, if you're not using them, close them. ask yourself, what apps do i have installed that require wakelock permissions. those are the ones who will drive android os through the roof. latitude. maps. email. feeds. even games can trigger sensors and not let go of them properly, leaving your cpu always working. check cpuspy from market.
turn off autosync. you're working right? no point getting distracted over some lame ass post on fb or some worthless spam in your mailbox.
Ok, so now this is weird. I don't have any apps keeping the phone awake for very long, but the wake counts are retarded, take a look at the attachment. The time is very low, but the count is over 2k. The phone is at about a 75% wake time. This really doesn't make any sense.

With ICS what is everyone using to figure out what apps aren't letting the phone sleep properly?
Spare Parts isn't working.
I've tried uninstalling about everything and I can't get this phone to sleep.
This is exactly the post I wanted to make today, glad I searched this one out.
I have few apps installed, and battery is going well for me. I'm a moderate user. I get about 20hours out of a charge.
I notice that even in airplane mode, my phone wakes up 3 or 4 or 5 times during the night for 5 or 10 minutes at a time it seems. What could this be? It's not data as I'm off wifi and in airplane mode. Any ideas?
Thanks all.
I've also been experiencing fairly high CPU awake times and was curious as to how I could track it down. Haven't found anything much yet in the way of apps, but I've turned off a lot of unnecessary Google syncing and an hourly sync of my Exchange account and it seems things are better now. I'm still getting awake times 1h30 greater than screen on time though.
I am seeing high "Keep Awake" times on Android OS Spare Parts force closes when I try to check Partial Wake usage so not 100% sure what this could be.
Wondering if this is the cause of some lower-end battery life we're seeing. My only thought would be LightFlow that is causing this (maybe to wake up for notifications). I thought I read it somewhere, but not sure if it was debunk'd or not.

My phone seems to be getting pretty awful battery life lately. Over 9 hours (only 1 hour of which was screen on time), it's down to 22% battery. The phone has been sitting (screen off) for a good hour or so and when I picked it up, it's warm as if it's been awake. Android OS is showing a Keep Awake time of over 2 hours - twice the screen on time.
Following the advice here, I dumped my wakelock.csv file (which is actually a tsv but that's another thread).

But frankly I have no idea what I'm looking for or, more importantly, what to do about it. What is "main" and why does it have such an insane active since time [is that a unix timestamp?]? Why do wlan_wake, keyevents, and event1-226 have such high counts? I'm usually pretty good with this kind of stuff, but I'm at a bit of a loss with how to interpret this data :/
I also have the CPU undervolted (Gummy 0.3.0 with imo's kernel) and running at 350mhz most of the time. And frankly, the battery lasts about as long as you would expect if the phone were awake all day at 350mhz.
There's the problem, though. It's running at 350mhz most of the time.
Now, I should clarify this by saying that I just (as in, a few minutes ago) disabled Google Talk, Google+, and the "backup to google's servers" setting and already it seems to have made a huge difference, so I THINK I may have already found the problem. Before doing this, 350mhz far outweighed "Deep sleep."
Thanks to anyone who can help!
So perhaps my post was pre-emptive but disabling those three things seems to have solved this. It's cool to the touch while idling, and more importantly, the battery seems to be doing great now. It was losing about 10% an hour and now it's about 0.5%/hour while sleeping.
Again, I disabled:
-Google Talk
-Google+
-Google backup (In Settings > Backup & Recovery).
I don't know which (if any one thing) did it but it's DEFINITELY better.
What the heck killed my battery? This is with the extended battery and I started from a full charge after flashing a new rom and clearing battery stats..
I turned off all connections, and turned off sync.. Sat the phone down and went to bed after about an hour of web surfing.. I went to bed with 70% left and woke up 6 hours later with 37%...

Its all in the last screenshot. Keep awake time is huge. That's the bug if I had to guess.

That keep awake time is normal, nothing strange there...
Your story of browseing for an hour then going to sleep for 6 hours doesnt match your batteries' graph.
According to your story, there should have been a sharp decline from browsing web since the screen would be sucking the power, then a very slight decline from being idle, something was either running in the background (facebook maybe, it has a high % of usage) who knows?
Yeah idk.. If you look at when wifi was on that was when I was browsing.. Then after that there is a steep decline which doesn't make sense to me.. I don't think it was Facebook or anything because all data/sync was off...
I know it takes a day or two for a new rom to settle in but I certainly wouldn't think it would have that large of an impact

I read somewhere that there is/was a bug where after a reboot Google talk or maybe google+ launches the camera in the background which keeps running until you manually open the camera app and close it. I believe I read it some where on Franco's kernel post. Not sure if the bug is still there and if it's the culprit here, but might be worth investigating.
Hey all,
I just thought I would post this as I thought it was quite incredible.
I don't know what HTC's stats are on 'standby time' (which is usually how long a phone will last with no radio gear active) but look at how long my Desire lasted when I took the sim card out

That's 302 hours
Just Sayin'...
Another thing that I noted was the vast amount of 'awake' time vs 'screen on' time, sometimes lasting hours.
What does android have to do so desperately whilst the screen, radio, wifi, in fact everything is turned off??

Its not Andeoid really. My best bet would be that Go Weather app.
via xda app
I'm not entirely convinced that it is, I could uninstall GoWeather or do a /userdata wipe and retry to see if it'll last any longer?
Even if you put it on airplane mode, the apps you have would still try to wake up every now and then to try and refresh themselves. If you have a resource hungry app then it will wake your device to do the task it needs to perform. It may or may not be go weather app but there is something installed on ur phone that is keeping it awake even on standby. That's what I think anyway.
via xda app
Ha ha ha ha...looks about the same as my desire. I got one hour battery life on idle once with 3G off, wifi off and most of my user apps killed.
My phones been charging for the last four hours and it hasn't moved from 75%. It dies in ten minutes If I use the data connection when it's discharging.
I can't seem to get the battery results people are claiming. It seems like I lose 10 percent usage per hour during the day. I am starting to think I might need to replace my battery. Last night I left my phone unplugged and It drained over 25 percent with 7 hours sleep. When I installed the rom I used the wipe flag. I haven't touched a CPU controller cause it was suggested not to.
How do I find out exactly what is draining the battery so much?
I heard about battery calibration. I have read about a few techniques. I have also read that it is a placebo.
I am not sure what to do. Here are some screens. The drainage doesn't seem normal.

Battery life really depends on the user much moreso than the rom. are you constantly using gps? google location? Wifi? Facebook sync? Twitter sync? Google talk? Other im's thru social hub? max screen brightness? constantly receiving calls and texting?
All of these factors influence your battery life. its probably not the roms fault.

I am not saying its the rooms fault. I am trying to figure out what is causing the drain. I don't use social hub or the Facebook aphp. Only thing I kesync is Gmail, contacts, calander. Also, I use gtalk. I don't GPS at all.
Something is draing the battery.
