Insane Battery Drain issues. [dying in <4 hours]

Using battery optimazation processes like juice defender, and even having advanced task killer working, lowering my brightness, and otherwise just having everything turned off like wifi, GPS, and all that business, im still seeing OUTRAGEOUS battery drain,
using the cyanogen nightly build.
this morning in 25 minutes
lost 16 percent battery
after coming off a 6 hour charge..
So.
the question is.
Where to start?
What to do, my phones just not makin it, its dyin all the time.

There are a few suggestions i would make. Just for background information have you used other Roms and if so was the battery ok for them or is this the first custom rom you have used? (just to compare to see if it is a new issue you are having with CM)
ok first i would get rid of the task killer. they do more harm then good Android will auto kill tasks and MANY of the tasks it kills are just stored in memory and are inactive causing little to no actual battery drain.
you can turn GPS back on it doesnt drain battery when not i use and can be useful to ahve on if you lose your phone.
If you havent done it yet search the forums and download SetCPU (or get it from the marketplace for a small fee) there are several posts about battery saving profiles on the forums or you can find one here.
A good post that has worked from some is to turn enable always on mobile ON (if previously turned off), turn auto sync ON (if previously turned off) TURN news / stocks/weather - OFF but keep your single google account turned ON.
I have no idea why or if this would work but have seen posts saying when they did this it did actually help.
If you havent tried to re calibrate your battery or the HTC charge method yet i would try hose as well (calibrate by charging to full draining it all the way till it shuts off then charge it back to full with out interrupting the charge.) The HTC charge method is to 1)charge the phone 8+ hours 2)unplug it and immediately turn it off 3)charge it for 1 hour. 4)power the phone on 5)unplug it for 2 minutes 6) then charge it on for another hour.
If you still arent getting very good battery life you can look for the app SystemPanel, if you purchase the full version you can get a history and see the top apps draining your battery (should let it run at least 24 hours while you use the phone normally so it can build data) this should show if you have an app that is hogging the battery. After all this if you are still having problems then you may try another rom or you may have a bad battery.
If i had to guess if this is a new issue i would bet that since you wiped to install CM6 you lost battery stats so a calibration and htc recharge will greatly reduce the problem.

your reply absolutely kicked ass, ill start trying all your suggestions tomorrow, im so happy i got an amazing answer from someone here and not flamed for being a dumb noob.
thanks again!

1. Get rid of CyanogenMod, flash Snacks 9.7 or DamageControl 3.2.3
2. Get rid of task killer
3. Turn off 4G/Bluetooth/GPS

To tell you the truth get rid of Juice Defender. I have never found it to help at all. It could even be the thing that is killing you. Get SwitchPro and and add the data connection to the widget. If you turn it off when you aren't using the phone, I have gone 2 hours without seeing 1 percentage drop. Just tapping a button to turn it on when you need it is nothing, and it takes about 15 seconds to reconnect. Juice defender is supposed to be doing the same thing while the screen is off, but as I said I don't think it works.
Other than that like Omega said, SetCPU really helps especially when you have the screen off if you set up the profile for everything. His advice is pretty solid, I just found another battery recalibration to work better which is to charge it for 8 or more hours with the phone on, unplug it, and then shut it off. Then plug it in and wait for it to turn green again, and unplug it wait for the light to turn off and repeat plugging it waiting and unplugging it 10 times with the phone off. Each time takes only about a min or so.
And there is no reason to get rid of CM, I use it and get equal battery than I did with DamageControl.

No problem at all i did a LOT of research and fiddling before i got my battery life to a level that i found sufficient. I use batterydefender/ultimate juice add on and it does turn off and on my 3g once set i had it set up right. Juice defender says i get x1.6 battery life right now according to it. I will say when i had juice defender alone it never said anything but x1 so it may be the add on helping. According to SystemPanel it uses almost no battery power (over 2-8-24 hours all show under .1% to give an example swype shows .1% and i do roughly 40 texts a day and very little keyboard use otherwise) so i dont think it is the main cause but you can always try the suggestion to turn off/on data yourself as well.
Any way let us know how everything works out for you and if you are testing each one at a time what made the biggest difference (i did almost all my battery saving stuff in bulk so no idea which one gave the most benefit for me just know doing all of it worked lol)

Turning 3g off and data for longer battery

Is 3g signal the same signal if I turned it off and just had 2g? Why I'm asking is I usually have 0-1 bar at home and I know poor signal strength causes battery drain. If I go 2g will I have more bars or the as I would in 3g?
I'm asking this because I have been told when I bought my last phone.. tp2 that it had to have a data plan or nothing will work. So my question is and have asked before but never have gotten a response is.. if I turn data off.. will I still get incoming sms? Im I better off getting juice defender then? Will this help? That is.. is sms workable with data off.

SMS is 1X. You don't need data for SMS texts. Texting is available on even the OLDEST non data phones.
Now, if you turn off data, you've pretty much eliminated most of what makes a "smart phone" smart.
Spare batteries are cheap, as are several different chargers. One for car, one for office, one for home, one for travel, etc.
Better you get into the habit of whenever you're near a power plug, to plug it in and let it charge. Once it becomes an ingrained habit, you'll not worry about battery life as much and you'll get much more enjoyment and use out of your phone. Besides, better get used to it. Processor speeds, power hungry hardware keeps advancing, battery tech doesn't.

I have 3 batteries and a tp2 I use to charge the others while not in use so always have a full battery. I don't sync anything but my email. I can always turn the data back on for internet or anything I'm using for internet. Why I mentioned juicedefender... also I underclock and undervolt. Just looking for a longer battery life. I don't get more than 4 with moderate use.
Edit: one doesn't have to get use to it if there are ways for longer battery life. I'm sure you have all the accounts sync and checked, screen brightness set all the way up, 4g on, gps on, and overclocked and saying get use to it its a smart phone.
I don't have 4g and I do use the internet a lot and check my email. I get my email to sync when I chose to look at my email and don't need to check every so often wasting my battery. Not everyone uses all the stuff you can use the phone for or as much as someone else.

You're saying you only get 4 hours life?????
I keep wifi on, BT on, data on.
Between 8am and noon, I've browsed, made 2- 30 min phone calls, updated 3 apps from the market, played (shhh, don't tell my boss) 3 different games for at least 15 mins each, checked the local news. and I'm at 82% using the stock battery.
Also, have exchange push enabled, gmail pull at it's quickest interval, NOT overclocked, not running any task killers. No 4G here, so that's off and GPS and NETWORK location are also both off.
If you're down in 4 hours, you have a different issue. Better install a few monitoring programs to see what the heck is going on.
Granted the 1500mah battery is way too anemic for this phone, you should be able to do better than 4 hours.

I agree you defiantly have something going on causing a battery drain. I used to get 6-8 hours with moderate use and have worked a lot of different things to finally get up to 14016 which i am happy with (i still dont see how anyone gest 30-50 unless there "moderate use" is not touching the phone except to have 1-2 calls or something on the break.
i recommend the paid version of system monitor. it lets you see your battery drain cpu usage and device usage. it also has a history option that will let you see which apps use the most power. The only other thing i can think of is you have an app preventing the phone from sleeping so that your setCPU profile and juicedefender are not doing anything most of the time.
as far as turning data off. You can receive SMS, you receive phone calls obviously, you can not download MMS or anything else requiring internet data. there is nothing wrong with turning it off when nothing use. (i personally use ultimate juice so that unless i have my screen on and unlocked or my phone is on the charger data is off.

Mind sharing your exact setup? Rom/kernel etc. Seems like your getting pretty good mileage.

I leave my phone on Wifi all day at home (no signal either, 1-2 bars) and battery drain is minimal now and it's not constantly looking for a data signal. I go approximately 30+ hours on 1 charge

I have the system paid app already. My problem is I have the worst reception where I live. Usually –105 to -118 and -120 I heard is no reception at all. So its more tower pulling and increasing voltage to get a reception. So I'm trying to do what I can to save a little battery...

Rooted stock, deodexed. Netarchy kernel. Have old airave at home for voice, and at home, I use WIFI. GPS doesn't seem to have that big of a drain
I was slightly incorrect, I do have setcpu profiles. Thought I had them off, but they are on, but NOT overclocked. For battery >75, or on power, default max, 384 min, conservative. Screen off, 384/384. Brightness is NOT high as I work in a well lighted workspace. Sometimes I do turn off WIFI tho. It'll fight with bt on occasion. Same freq. But usually it stays on. I do use phoneweaver for profiles. And I also use TASKER to create specific app profiles. IE turn on gps, wait 15 secs, start gps capable app, turn off when app closes, etc.
I also did the battery calibration "trick" and every now and then I clear the battery data from recovery. Not sure if that helps/matters or not.
I don't use the camera app, nor do I use friendstream. GTALK (known battery killer) is set to NOT running/syncing.
Is it great battery life? no, I'd say average. About what I'd expect. I'm not expecting 24 hours with it while using it and not recharging. When I'm out and about, I'll plug it in any chance I get, and also have spare battery or 3 from my TP2. For a full charge, I have an external battery charger. I was using the TP2 as a charger but don't trust it's charging circuits either (yet another HTC product. lol)
I just checked and I'm at 49% assuming the "battery guage" is accurate. 8 hrs to 49%. Few texts, another call, some more news, using TIKL. Time to plug it in and let it charge. But it was a nice test to see how long my normal use would last.
If your signal is that low (to the OP), try to get an airave, esp one of the newer ones with 3G/EV capability! I am going to call and ask if they'll replace my older one with the newer one.

I already thought of that option. Don't have internet here... downfall..

Anyway to automatically toggle 2G when the screen is off?

So is there a way to make my G2 to automatically switch to 2G when the screen is turned off, and then revert back to 3g/hspa+/etc when the screen is turned back on? I'm assuming this would improve battery life right? Or will it make it worse since its constantly switching signals and such?
Thanks for any input guys!

It's possible if you use CPU tuner wich has profiles specific to 2g speeds. Assuming your rooted of course.

Juice defender does this job, 2G or no data its up to you whenever your on sleep
Fly like a G2

I'm not sure how much of an impact this would have on battery life.
I have not tried it but from my experience, the phone turns from a Sprinter to a Marathon Runner when using 2G versus 3G/H+
I would think that the constant switching of signals would hinder the battery life, but if you leave your phone alone and on sleep regularly then it may help. The screen on my phone is always going on and off from regular use so this isn't really an option for me.
Another thing to consider is that if you have to install a program that does this 'switching' task for you, that program is another process that must always run in the background, draining the battery.
Might just want to give it a shot and see how it is after a few days use, if its worse you can always go back... Just my two cents.

+10000 for Juice Defender. Works like a charm, but as stated above if you're regularly turning the screen on/off back and forth (aka lots of texting or w/e) Juice Defender might not help too much because toggling the data on and off constantly does hurt battery.
Now i should add that Juice Defender doesn't work on Gingerbread yet, and I've had great battery life keeping 3g on all the time.

[APP] Juice Defender - HUGE help for extending battery.

I downloaded and installed Juicedefender ultimate.... For the first time in quite some time, I was still at 50% battery after 8 hours of regular usage.
It'll turn off wifi and turn off data when the phone's sleeping and only sync when the phone is turned on or by schedule ( I set mine to every 15mins).
It's worked great for preserving battery life on my phone when using Dman's PACMAN 18.2.

And this is with the stock battery?

This one gives me 2 solid days of use with extended battery.
Couldn't believe how quickly battery died without & how long it seems to last with.
Plus the guy's on here. Support local talent.
Even gives "Pro" free to XDAer's.

yes stock battery .. the other day I was at 30% after 15 hours ..
Juice defender actually memorizes where you are (somehow) and will turn wifi on in my house and this other site i go to where the signal is weak .. just auto switches it on for me when the screen wakes up, really really great app.
This other one above, i tried the version off of the store but juice defender kicked its ass ... Soooo many features in JD its a bit confusing in areas to setup, but the battery life is by far worth the cost of the pro app. Ill try the Battery Saver app that MoodSwinger posted above, see if theres a big diff or not.

Standby Battery Life?

I know there are threads regarding battery life out there, but most are all about usage and screen on time. My Note seems to be on par or at least close as far as screen on time. However, I'm just curious as to what all of you are experiencing as far as standby time. I've gone through the battery life guide and turned off most features I don't use, but the standby time still seems pretty lame. From a full charge, its been 3d 5h on battery with zero screen on time other than checking the battery stats right now, and it's down to 9%. Android OS consumed 57% and Google Play Services 33%.
I know I'm comparing Apple and Oranges here, but my 4th gen iPad I have for work hardly drains at all without use. After a week of standby, the iPad will only drop about 5-10%. I feel like this tablet should be capable of the same, and possibly will be after I root and find a good rom (also don't like to see any Apple product out-perform any android based product). Am I alone here?
Basic setup: Stock Rom (not rooted), Nova Launcher (prime), GPS off, Bluetooth off, reading mode off, multi-window off, screen mirroring off, s pen detection off, all samsung crap off (air view, etc), and others. Basically the only thing on is wifi.

I only have wifi off during standby and it drops 1-2% every 12 hours

You might have a tough time getting people to compare their standby time with yours... most people on this forum either use their tablet for work and if not are too in love with their baby to let it sit there untouched for days on end When I couldn't use mine for 12 hours, it dropped about 3% with WiFi and GPS on

Yeah it is too hard to not touch it for days on end to test this. Turning off wifi while in sleep mode will help a lot. Go to the Connections tab in settings and hit the hardware menu key, then choose Advanced, and change Keep wifi on during sleep to never. That has helped me a ton. Right now mine is at 2d 7h 40m uptime with 4h screen time and it's at 32%. Even with that setting on, my iPad mini still gets better battery life. I have left it sitting for 2 days before without touching it and found it sitting at 92% battery life with wifi always on. My guess is it's something to do with the OS and iOS is just more efficient. That's why even with weaker hardware it can still outperform android tablets.
Also I'm still running a lot of the things you have turned off. You might want to also try Greenify. It has a non root working mode now, but works best in root. You can also try Wakelock Detector to see what apps are waking your cpu, so you can see what to Greenify. If you root you can also try an app to freeze apps as well like Titanium Backup and Rom Toolbox.

yeah, forgot about greenify. you have to be rooted though an need either the donation version to greenify play services(that's the battery killer) or use titanium to make it a user app to greenify with the free version. it's sad that google is the worst culprit with battery drain on all my devices.

I get 1-2% battery drop every 24hrs of standby. WiFi must be off, it not hard to just pull notification bar down and touch the wifi section off whenever you think you wont use the tablet for a while - takes like 2 seconds.

I have yet to try my battery life with wifi off, so I think that'll be next. I really don't need it connected while the screen is off, so I'll change that setting first.
I figured it might be difficult to get a good response for this question because I too have a hard time putting the thing down. Was just traveling for work and had it in my bag those 3 and noticed the battery drop. I appreciate all the suggestions and welcome any future ones. In the mean time, I'll be experimenting as well and report back if I find anything causing the drop.
