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.
Have you checked your partial wake lock in spare parts?

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.

Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.
I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.
maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?
I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.

My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.
Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.
I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce
VPN services
Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.
I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.
Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.
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 =/

I couldn't believe it either, he had 3G on all day and everything and we barely get any signal at all in class. On for almost 8hrs with more than 70% left. I was at about 53%
So...I'm using 2.1 and for some reason when I'm not even using the phoone..the battery drain is ridiculous. Since I'm new to 2.1, does anyone know what is causing this? Any processes I need to end? Any thing I need to remove?
I'm straight up rooted stock 2.1. No custom roms, just a custom kernel. I only downloaded Pandora, Wordfeud and SetCPU.
Edit: I also wanna add that I leave on 4G as well and I see it idle out and when I turn it off and leave it off I still experience the same amount of drain so I dont think its 4G.
And for more details on the drain...I went to sleep for about 3 hours and during that time I went from 91 to 42.
Edit2: Im gonna actually see if maybe it was just the kernel...I was using the first version of a kernel, not its latest version so Im going to put on the latest. But still, Id liike to know if it was a common problem and how most people fixed it.
Kill the omadrm process with each phone reboot. (Forgot exact name, but that is close) If you aren't always in a 4g area, having that radio always on will drain the battery.
Sent from my SPH-D700 using XDA App
Edit: Also double check your phone standby time and see what percentage your Time Without Signal (TWS) is at. Toggle Airplane mode after each reboot will correct that bug.
Also fyi you can use Tasker to toggle airplane mode for you automatically every boot

It you can just.install spare parts and.look. also check your time without signal. If you don't reset your radio its prolly 50%. Whether.that is.cosmetic or actually does cause a battery drain its still good to do.

Battery life even with removing a few apps is pretty bad.
I think the most I got after a week of tests was about 18 hours and that was with almost no use.
Try downloading JuiceDefender from the market. It's free. What it does really is enable/disable your 3G/4G/WiFi connection when your phone is not in use. It also enables it every 15 minutes (default setting) to get email other updates such as weather. I am not kidding when I say went from an 18 hours to 72 hours hours. Granted, that was with little use.
Can download JuicePlotter as well to get an idea of how your battery is dropping and holding.
Side note that WordFeud constantly runs in the background, so that WILL rape your battery. JuiceDefender will keep it in check. Best app I ever got.
For reference, under 2.1 with JuiceDefender I would lose only about 1%/hour at night when I was sleeping.
Under 2.2 it's more like 2% per hour >.> and I've yet to figure out what's draining it.
I thought I'd chime in since the OP mentioned Pandora. After installing Pandora I noticed my battery drain had gotten significantly worse even when properly quitting out of the app. After uninstalling Pandora battery drain has normalized to the way it was before.
Also, setting your network to sprint only helps with battery too.

maybe where you live it does, but thats an awful idea if you are in a town with little service because it will spend more time searching for service because it can't roam (i live in the middle of nowhere in new hampshire).
instead try to update your PRL. download the SDX stock app removal apk. remove the drm crap. and reboot. then charge your phone all the way, reboot into cwm, and reset your battery stats. then let the battery drain all the way and recharge. that should improve it significantly. thats what i did and it worked pretty damn well. battery life is upwards of 36 hours nominal charge now. and my phone used to drain battery WHILE i was charging it if i used it at all. and that was with a 1 Amp charger. also dont let your battery overcharge, mine seems to drain easier when i leave it plugged in all night.
This seems strange.Yesterday after upgrading to gingerbread ( with the RUU because the OTA didn't work for me) I got a huge battery drain.Over the night I got a loose of 40% and now only 3 hours after unplugged and lost 20%.
I only took a few pictures and a phone call.
Only few apps installed since i got this rom since only yesterday.
Anybody experienced this and is there a fix?
Hello,
I can confirm this.
I have also a high battery drain with ALL Android 2.3.* ROMs.
I use the recommend Radio for each ROM and I've checked the RIL to be sure the Radio is correct. But doesn't matter, current in StandBy is between 30 and 50mA.
Only if I turn off WLAN and Mobile Intenet, then I have normal values between 3 and 5mA.
With FroYo I can leave WLAN and Mobile Internet enabled and I had 3-5mA in StandBy
It could not be an application, because I've tried this with a fresh install without Google account to avoid the installation of external apps.

you'd have to edit the build.prop and change the rescan time from 15 seconds to 30, 60, 90 or 120 (or whatever you perfer the rescan intercal to be at)

Try resetting the battery stats by doing the whole charge, lead out, charge, turn off, charge etc. thing.
Also, whilst not a stock RUU I did find it took a few days for the battery drain to calm down a bit. First instal lowest was around 50mA but adfter a fe days it went down to 4-5mA.

you'd have to edit the build.prop and change the rescan time from 15 seconds to 30, 60, 90 or 120 (or whatever you perfer the rescan intercal to be at)

Thank you for your help
What does that value do?
Is that the rescan value of WLAN?
The current stays high even if WLAN is off and mobile internet is on.
Only if both are disabled I get a low StandBy current.

Yes I know this, and I've tried this every time I was flashing a ROM (I mean reset the battery stats)
After a few days? How many days do you mean? 2, 3, 4, 5 days?
@both
But why this problem does not exist on froyo?

Varies but on average I find it takes about 3 days to settle to a point where I see a consistent drain.

Unknown. It's not 100% due to GingerBread as I've only seen a handful of people complain of this issue (relatively speaking). I see more people saying how much better their battery life is after the update than saying it's poorer.
Doesn't help I know but makes me believe that this is maybe a Network / Radio issue in that the new Radio with GB does not play well with the Network. We had this a few times on the HTC Hero.
Ok...i have airplane mode on for about 2 days.in those 2 days i almost didn't use the phone and got only a 7% lose.As soon as i used the camera(recorded around 15 min) it got down to 50% .
I will test it tonight widought airplane mode on and see the resoults.Also wifi seems to a lot of battery in comparance to froyo.

I haven't noticed these problems with CM7. I got 2.5-3 hours per 1% of drain in standby using juice defender.
If you are finding that turning off data etc is fixing the problem use juice defender. Even the free version will help a lot as it will stop your phone using data willynilly and instead turn it to a periodic sync. With the paid version you can have it stop all together during certain periods or increase doing certain periods. Aka stoping at night and extra during busy hours at work.
Should be a good fix, though it is only covering up the underlying problem still.
Can't really recommend the app enough. With it my phone only uses data when I tell it to (like opening facebook app) or periodicaly to sync and check emails etc. I do use the paid version though for the extra features.
totally agree. i have been using juice defender for about a week. its been a big help. just bought the ultimate a few min ago. going to start customizing.
sorry that i dont have any data yet to back up my statement. maybe in a future post.

im using Leedroid 3.0.3 and i dont get any such battery drain..
tbh im getting a better battery life from GB than from froyo..
on standby currentwidget shows me between 4-7ma with wifi on... with a peak once in a while..and i lose abt 1 to 1.5% per hour
with wifi off i get about 3-5ma..
i dont use mobile data much so cant really comment on that..
try calibrating your battery and try changing the scan interval in the build.prop... i normally keep it at 90...
i never used any battery saving apps, so cant comment on their performance either...
go to wifi advanced settings and untick Best Wifi Performance... that also helps a lot!
hope you get your problem sorted
Thank you all for the help
The issue was not with gingerbread...I just left my phone one night with wifi turned on and lost 40%.But still when I was on Froyo wifi wouldn't loose so much battery.Now I loose almost 2-3% every 15 min if surfing the web with wifi.
And about changing the scan interval in the build.prop...How can I do that?Do I need root?
I'm also having battery problems, but mine are a little bit different, if I'm on wifi it uses between 3 to 5% with a peak now and then. if wifi is off and I'm on 3g, it's between 5 and 500 ma and you see only peaks if you check currentwidget. anyone a clue? working on ARHD 5.1.6 now, but problem was there since version 3
I have battery problems also, my battery dries after 1 day of use. For example this morning, I unplugged my phone full from the charger at 10 am. I went into town, listened to about 20 minutes of FM radio. When i stopped the radio, I still had 98% left of the battery. OK so far. After, I talked for about 5 minutes, sent 4 messages and played for about 15 minutes. I arrived home at 2 pm with 75% of battery left. That is 25% in 4 hours.
I was on 3G, but with Mobile network off. BT, WIFI, GPS off. A few days ago, I tried running the Battery Calibration app, but seen no improvements so far. My phone is routed, 2.3.3 and has Android Revolution HD 5.0 RC1 ROM .
I expected the battery not to last for long, but this is ridiculous.
Help me, please!
I don't know if that will help, but I sometimes switch to 2G networks as HSDPA is using quite a lot the battery.
I have a DHD running 2.3.3, and it's definitely the mobile standby bit which is first in the battery use screen (33%). It was true before 2.3xx but now it's a bit more - annoying in other words.
I have to admit, having to switch to 2G networks is a bit of a pain in the *ss, so I'll check if juice defender give me some good results tomorrow and will post a feedback there.
Maybe try AR 5.1.6. + he recommended radio. It works wonders. the battery life is improved a lot...
malik
Juice Defender works very well - with basic settings I still have 35-40% of battery by 7pm.
furstrated with the battery life...
hey guys,
so this is my first post and all i've done up until now was to read... i'm afraid not real solution has come up.
i have:
Leedroid 3.1.2 with the recommended radio and i ran the script for Full Wipe 1.5 and cleared the battery stats, i did a fresh install and then didnt restore from backup - just installed everything from scratch. i hoped it would be ok, but when i woke up to check the current widget log, i saw that in the middle of the night he climbed to 150mA and stayed there draining about a 1% of battery in 3-4 minutes (!!!)
what can i do? 'where is my droid power' shows only HTC Sense at about 3.8%
please please help... thanks!
Hey everybody,
Just made the jump from the iPhone 4S and have done the custom ROM/kernel thing the past week. Things were good at the start but I feel them slowly deteriorating.
I find my battery life during sleep has become much worse than before. I mean, it still kills the 4S which would see ~25% overnight. But I'm seeing 10% overnight right now, and was ~2% earlier in the week. I normally have my phone on the charger at night, but didn't last night and I'm kinda glad I got to see this. Makes me realize why I was likely chewing through more in the day too.
You can see what I'm running below in my signature. Last night I had 5 instances where the phone woke on its own. Likely due to emails coming in.
Am I expecting too much from my modifications? Am I doing something wrong? I'm ready to toss AOKP aside because of other issues anyway, but yesterday I also read it was known to have some excessive battery drain as well. Without turning this into a battle to defend the ROM you use (like half the threads in here), if you have other suggestions, feel free to throw in a ROM suggestion. I'll attach some pictures of my battery screen so anyone willing to give me a hand can help.
Thanks in advance.
I had this problem when I was running franco too. Switched to leankernel and never looked back. I get about 4-6% drain overnight as long as I dont do something stupid like leave something running by exiting with home instead of the back button. I also have wifi on 24/7 and gps off unless im nav'in. No BT

I'm hesistant to blame the kernel. I was using franco prior to AOKP without issue. I didn't make that clear in the OP. I went 4.0.4 Stock -> Stock + franco -> AOKP b31 + franco. Things were good the first two steps and I'd like to think the first few days on AOKP.
Perhaps I have some background processes chewing battery - but there's nothing with a higher battery drain than Chrome beta with 2%. My phone idle and Cell standby had huge drain though. Could a weaker than normal signal cause this? Could my radio be the culprit?
Steps to best diagnose idle battery drain.
-Install CPU Spy and Better Battery Stats.
-Charge phone to full and let it run for several hours undisturbed (easiest to charge before bed, then unplug it when you know it won't be used till morning).
-Take quick note of your % loss per hour. Around 1%, you're golden. 1-2 is pretty normal. >3 and you've got issues.
-Launch CPU Spy. Most of the time should be deep sleep (we're talking about 95%). If your phone has been awake a lot, there's either an app that refuses to let your phone rest, or an OS/Kernel issue. If it's not extreme but noticeable, you likely just need to reign in settings on some apps to keep them from syncing so often or working in the background.
-Launch Better Battery Stats. Select Partial Wakelocks from the menu. These are all cases of apps waking the phone up, sorted by length. Go look at problem apps' settings/consider uninstalling if you don't need them. Kernel wakelocks should be low too.
Keep in mind that the goal here isn't really to get all these things to zero so do not obsess over small showings. Facebook with push notifications but updates set to never keeps my phone awake for about a minute or two every night, for instance. So does Handcent SMS. If you flash a rom and your phone needs to do a lot of syncing it's likely to show up in this kind of test as well. But for a night with nothing going on, nothing should be keeping your phone up for more than a few minutes total.

Weaker than normal signal can kill a phone battery, when I'm in lecture out in the bumfuck nowhere school I go to, I get -100 to -120dbm, which kills my battery while i'm at school. If thats your situation not much to do besides hope radios may increase your signal, but if not then your basicly as SOL as i am and may have to just charge it
