I'm running CM6.1 RC2, and the past couple of days I have experienced excessive drain, mainly in the first 50%. I attached a picture of the issue. I went to spare parts battery history to see the network usage, since in the about phone battery usage cell standby was 84% of the battery usage, and under network usage there was just an entry for 0, using the most network. When I clicked on '0' the settings application crashed. Yesterday it dropped 35% in 2.5 hours, before it slowed down. It was ridiculous, never used to have this problem, and the battery is only a couple of weeks old so it has to be software. Today it is at 53% after 7.5 hours, which is pretty decent, but at around 70% I disabled 3g and background data to save some energy for a few hours. Is there any way of figuring out what is causing this, or should I reflash? Could it be a CM6.1 RC2 bug? Anyone else having this issue? Thanks in advance
BTW I have no idea why the dialer was so high in usage I only had like MAYBE 15 minutes total of voice calls in 2 hours. The 0 is what I'm concerned about.
Anyone? Bump? No one else is having the issue? Still happening to me on RC3.
I've been getting that problem too.
I used to have battery life of up to 4 days (Mostly standby), now I'm lucky if I get 1.5 (Same usage).
I went in to spare parts and it crashed for me too.
Battery drain here too since cm 6.1

Well '0' is he system's ID, 0 is root. In the graph the blue is bytes sent, red is bytes received. Have you checked other usage like CPU usage? That might be a better indicator of what's using your battery. Then from there you can start to narrow it down to a specific process or app. I'm using the latest nightly and don't have that issue, never have. I use a bit more battery than I think I should but nothing crazy.
Do you have wifi or bluetooth on? Those drain your battery like no other.
I havent used wifi at all today, unplugged at around 6:30, it's 3:45 now and I'm at 63%, but from around 9:50 to 11:45 and then from 12:20 to 2:20 I had airplane mode enabled since the time without a signal was at 70%, very low signal area. So it seems like for only 4 hours or maybe 5~ of non airplane mode time I should be at above 63%. I only had wifi on for a half an hour today. I'm considering going back to stock for a few days just to see the battery life comparison, and then nandroiding back to CM6.1. I always end up going back to AOSP-based roms in the end. I don't have a data plan on my phone at the moment, getting it today I'm pretty sure, so could all of the blue be from the phone continuously trying to access a website? But other people said they have the same issue and I'm assuming that they have data plans, so that can't be too much related. Hmm.
I also checked cpu usage and such like you suggested, there were a lot of things listed but all but two of them were too small to even have a bar. The two that did have a bar visible were minuscule to put it lightly, so that can't be an issue. Battery use in the about phone area always has cell standby at the top, normally between 40 and 80%. It would seem like there is way too much cell communication going on, moreso than normal. Cell standby stays at the top in even high signal areas, so it's not the signal levels. Kind of stumped here.
Well if the cell is in standby then it's linked to a tower and awaiting activity. Every now and then it 'checks in'. If it's doing that too often then that could seriously drain the battery. You're right though, I'd just switch back. Trouble shooting the exact issue wouldn't be worth the time. Maybe try flashing it again later, could have just been a corrupt download that didn't flash properly.
After conditioning my battery religiously (full to empty with every charge cycle) I am back up to about 15 to 16 hours from full battery to system shut down which is way better than the 10-12 hours I was getting when I first loaded RC2. CR_OTA ROM gave me up to 24-30 hours off of one charge with the exact CPU/2g/3g/wi-fi "routine" as I am using with RC2. Tracked battery usage with System Panel app and RC2 has a steady and even drain pattern ... an even diagonal line down the graph (100% to 0%). Cell standby uses a ridiculous 40% of the battery from full charge! On the stock ROM System Panel app shows plateaus throughout the day when the phone screen is off/sleeping where battery use is virtually non-existent. I'm going to load RC3 today and track the cell standby and battery usage. This time I am not going to use setCPU and just let the ROM run as the CM team designed it to be used and see if anything has changed. I tried this with RC2 and the battery still trended absolutely evenly from 100% to 0%. I can live with a 16 hour battery cycle for the CM ROM because it is very smooth and never has a glitch. The stock ROM is smooth as well but it has some buggy behaviors that I just cannot stand for and it does not run the latest GAPPS.
I've noticed i have exacly the same problem(was actually gonna post it when i found this thread)
Needless to say that on eclair my battery lasted ~48 hours constantly, not its drained in max 24...
The highest I have EVER gotten was 24 hours, and that was on a cm6.1 nightly build, pre RC2. I loaded cr_mod and experienced a HUGE drain. I had airplane mode on, just to test, and it dropped 7% in an hour, in AIRPLANE mode, with no screen on time. I went into spare parts and looked at the usage, and sure enough, "running" was at the top, with 99% of the time spent without sleeping. This has never happened before though, so I can probably attribute that to my modifications. I deleted a few apk's and de-odexed it before I flashed it, and I have a feeling something I did corrupted something else, so I'll flash plain old cr_mod and see where that leaves me. I should probably get back into the habit of full charge/drain every cycle. I used to do that until my battery started lasting longer than I was awake for, so I always had to plug it in at around 15 to 30%. I'll run some more "trials" and see what's going on.
Also, on an unrelated note, I love the stock rom, I always love the sense UI, but I hate HTC_IME compared to the froyo Latin_IME, is there any way at all I could port the froyo Latin_IME to the eclair stock rom?
Edit: also, I flashed dumfuq's OC kernel over cr_mod, could that have been the culprit to the battery drain?
Shouldn't be the culprit. It would drain quicker because of the clock speed but shouldn't be too bad.
Yes Latin_IME should be able to be used with sense. Just delete htc_ime and clicker.apk then install latin_ime and it's corresponding clicker.apk which you can get from various roms'. Btw, clicker is used to calibrate the keyboard so you don't have to install it.
NJAZ, what's the result on using CM6.1 without SetCPU? Big difference or not?

Actually, by process of elimination, the kernel was the issue. I remember hearing about there being a bug in the older dumfuq kernels with something idle being null, I really don't remember but it had something to do with sleeping. I flashed pure CR_mod and then 3.5 dumfuq and I experienced the same issue where it wouldn't sleep. I flashed 4.0, but I think it's too soon to determine whether or not the same issue with sleep is occurring.
I tried doing what you said with LatinIME.apk, I even imported the lib file from /system/lib on CM6.1, but the it was nowhere to be found in the system when I booted. It wasn't under keyboard settings, and HTC_IME was gone. I figured it was an incompatibility between froyo and eclair, since the stock sense rom is eclair and the LatinIME.apk is from a froyo ROM. Do I have to something more than just adb push the apk and lib file? I also tried installing it with a file manager, and no surprise, problem parsing the package. It's a system apk so I didnt expect it to be able to install via a file manager. Do I have to use adb install instead of adb push? I'm wondering if htc IME is so wired into the system that it won't work that way. What if I rename LatinIME.apk to htcime.apk or whatever the name of HTCime is and see if that works, because the system may be is treating that as the stock android keyboard, rather than a third party one, because it is labeled touch input in settings, just like LatinIME in aosp roms.
I'll experiment some more I guess
edit: Nevermind, 4.0 is draining as well, albeit less rapidly. Ah well. I guess I'll have to go back to CM6.1 if I want to do overclock. Shame, I love sense so much.
ANOTHER edit: nevermind, you were right, it isn't the kernel at all. It happens when I turn wifi off. I'm assuming that's because I don't have a data plan so it's continually retrying a server that it can't access. I don't know why it didn't do this on the stock HTC kernel, but I'm pretty sure it's the issue. If I turn wifi AND mobile data connection off, it stays at normal drain as well. Well, I'm at 11% and my battery app is estimating roughly 1 hour and 20 minutes remaining, so I don't know if that's GOOD, but I'll give it a good full charge tonight and run it tomorrow. I hopefully will have data activated tomorrow so I can really test it.
Hey guys new to the slide forum but not new to the site. I come from the G1 thread and we had the similar problem. How is your battery life on a 2.1 ROM? I have my phone rooted with a Sense ROM and it has 2.2 and i do see a bad battery drain as well. I remember froyo ROMs battery life may not be the greatest yet. I remember that was always a big problem over there and it looks like it still hurts here. Have you tried setcpu settings?
Maybe this information will help, i forgot to mention last time i posted that i'm not using a HTC device, i'm using Samsung Galaxy S, and there are more ppl with this problem on our forum aswell, so maybe someone can use this information correctly, i mean, it's either a program that's doing this or some strange freaky froyo process that not everybody has? or idk..
We'll need to get a log or something from one of the phones doing this and see if we can pinpoint the issue. Anyone experiencing this issue using compcache? Maybe it's doing some sort of background compression/decompression or swap is swapping too much while the phone is 'off'. Like I said, we'll need a log dump uploaded so we can sift through it.
As far as the latin_ime, try getting the one from a 2.1 vanilla rom. Check the slide rom bible for the 'senseless' roms like CM5 or something. That should do it.

Well my desire was to get the froyo latinIME onto eclair, since it's prediction engine was so much improved, but I'm getting used to HTC_IME so it doesn't matter.
As for the battery, for me at least, running the cmkernel from dumfuq, v4.0, I get BETTER battery life than the stock HTC kernel. Weird right? If I enable data I get tons of blue in spare parts, under network usage, for things like calendar and contacts. I'll have to assume that's because of the lack of data plan, my data plan doesn't become effective until december 9th. Otherwise, I have no excessive drain. It must be a cm6 issue, with cell polling. Cell standby was always up in the 70%+ range in battery usage in cm6, and on the stock rom it's around 27%. Wi-fi and display are highest, and I still get 20-25 hours.
I agree, to pinpoint the cause of the problem in cm6, someone needs a log to analyze, I'm not actually that smart with these things, nor am I running cm anymore, so can't really help there, but it'd be a good start.

Well I just recently saw this almost exact same issue (maybe not as extreme) on the samsung tablet running Cyanogen. They removed the phone, telephony, mms, and one more .apk to resolve it. This issue was caused by the lack of a use for those .apks but the system was still using them... a lot. It seemed similar but not exact, maybe some of us more tech savvy people can look into those and see if there's an issue.

Yeah that'd be cool. It must have something to do with that, since it's the cell radio sucking battery.

I flashed 6.1.0 stable, battery drain seems to be slightly less. I'm still at around 5 or 10% below where I was at this time on stock, with 9.5 hours off the charger, current level 57%. Although, I did use airplane mode for almost 2 hours, so really I'm like 10 or 20% below where I should be. I just can't figure it out, cell standby is at like 80% usage in this ROM. It's ridiculous, is it the polling intervals or something? How can it be so much less battery efficient than stock?
I flashed 6.1 RC2 with a low battery and had trouble with battery life. TMO's service was acting very strange for a couple of weeks and my cell standby was consuming a lot of juice. Flashed 6.1 RC3 with a well conditioned full battery. At first I used no setCPU just to see how things would go ... 11 hours from full battery to empty. Added setCPU to RC3 and got 27+ hours out of a full charge. Either TMO fixed it's towers or RC3 was better with cell standby because my network usage was not cranking overtime like it had been. Finally, I flashed 6.1 stable with setCPU and I average around 22 to 24 hours on one charge.
One observsation - when I first flashed RC2 I was really into my phone again. I was constantly tweaking it and flipping through options, testing apps, digging new Gapps, etc. ... bottom line I was just using my device waaaaay more than usual and I think that played a huge role in my (supposed) poor battery performance. All seems to be well with 6.1 stable.
So I've been running the RCMix3d for a week or two now, and everything has been great. Generally, after 16 hours or so I have 40% left on my extended battery (both on stock and RCMix3d). Now for the last two days, I've been getting this extreme battery drop where my phone dies in something like 10 hours.
I have no idea what it is, I thought it might be the newest facebook update (and facebook in the past was a CPU hog), but this time neither facebook nor any other offending app was appearing in the "Battery Use" chart. Everything seems completely normal, my battery use percentages are just about where they were when everything was fine. Watchdog is not showing any apps exceeding over the default threshold.
What can this be?!
Thank you
Run a dumpsys power command from a terminal. I bet you have a wake lock.

Too bad I wasn't patient enough to wait. I have reflashed stock already. Out of curiosity, what could cause a "wake lock"?

are you on GSM or having no signal ??
something like that happened to me ( battery dies quickly ) , and the reason was phone is searching for network all the time
