SystemPanel shows system using CPU overnight? - Vibrant General

Trying to figure out what was causing excessive battery drain on my phone, I downloaded SystemPanel and had it log overnight. I read that when the phone is unused, none of the apps in the "Top Apps" should show over 0.2%. I left my phone on the charger all night and the "system" app sucked up 1.2% completely unused. Apparently there should also be some kind of standby app showing up, and that is nowhere to be seen. I'm running Nero v5. Anyone know what could be going on?

In my experience, System Panel is not the culprit when this happens. I've had success with getting 0% battery drain on airplane mode overnight, and always w/SP running. (It's inconsistent, though -- I actually tried it just last night, and Market ended up jacking the CPU all night, even though I had killed Market hours before bed. Don't know why this happens.) I actually leave SP Monitoring on all the time, and generally get (what I consider to be ) great standby battery life.
To the OP: what were the top apps that were running (at more than 0.0%); and were they burning CPU the whole time? If an app/process is running the whole night, it seems to also "trigger" System to burn CPU -- but the app itself is the "real" culprit. (Pls keep in mind I know none of the technical details; but I've experimented a lot w/this.)
EDIT: sorry, just read yr post more closely. To address two more points:
(a) re: the "Standby" process -- this rarely pops up for me, even on the occasions where I do get a totally placid phone overnight w/no batt. drain.
(b) re: I left my phone on the charger all night -- try it without doing this (stay off charger & use airplane mode), and see what happens. I haven't had good luck w/leaving phone on charger: I wake up to same thing -- System jacked up -- and end up needing to power-cycle phone to get System to settle down.
(By the way, I'm totally stock JI6, and so can't address Nero etc.)

The standby process ("suspend") should always be near the top of the list if your phone is truly in standby in a given 8 hour period.
notverycreative - system always uses between 1.9-2.5% for me. It's the system processes and regular apps that you should pay attention to. Once I used Titanium to freeze Media Hub, the DRM Protection Processes, WiFi Calling and some poorly coded apps, my battery life improved significantly.
Here's some screen shots from mine over night.

Alright, I'll try doing all that tonight. I just flashed Bionix V so I lost my data from last night, but I'll try to recreate it tonight. I did get rid of the DRM processes and Media Hub, as well as SNS sync. I never installed WiFi sync for that exact reason.

Just spent the night on flight mode and nothing took more than .1% battery and the battery didn't drain much at all, as the meter read 90% before and after I slept, which was about 6 or so hours. It may have something to do with flashing Bionix, but regardless I am happy thanks everyone!

[Q] Battery life makes me cry

(I'll preface this by saying that I am well aware there have been a million threads about this, I'm sure, and I'm even more sure that there will be a million more. And I have searched, and searched, and searched some more, and I still feel the need to post this question. Flame me if you want. I'll use the flames to heat up some tea, or something.)
I bought my phone last Thursday, it got lit with service Friday. I went over the weekend and into Sunday with stock ROM/kernel, and decided to mix things up by rooting my phone and using the MixUp kernel to see if I could get better battery life.. and it didn't work too well. I mean, life went up a bit, but not noticeably so (maybe twenty or thirty minutes?)
After that, I flashed Syndicate, which had Xtreme Kernel. I calibrated the battery as instructed inside of Clockwork and went with it for Tuesday.. took it off the charger at 8:00 and it died around 4:00. Kept the same kernel and flashed Epic Experience and the attached JuicePlotter shot is where I am at right now.
My usage today has been light browsing and that's basically it. I've got the processor underclocked to 600 with SetCPU, and JuiceDefender and Superpower have been preventing any data from going on when my screen is off, and for the last two hours I've been listening to MP3s using the in-built music player.
This makes me cry considering there are people on here saying they're able to get much more life out of their battery, even with BT and WiFi etc. I'm aware that each phone is different and all that, but still.
All that said, is there a problem with my phone/battery, is this par for the course with the Epic, or should I just stop whining?
Thanks in advance for any help/insight.
A couple of things...get a task killer app so that you can kill the drm process which eats up a ton of battery, calibraing your battery takes 2 or 3 times going from full charge to zero and also, since its a new phone it takes charging to full and letting it get down to complete zero a few times before you will see better battery life no matter what else you do
Edit: oh and also definitely do the airplane mode toggle as well

Also, for each new Kernel you flash, you have to calibrate the battery.
Charge it to full, boot off, boot up in Clockwork, go to Advanced and Clear Battery stats. Reboot the phone, use it until it runs dead and shuts off, than plug it back in and charge it to full with the phone on.
Every time you flash a new kernel, you have to do that process so the battery calibrates to that certain kernel.
Also, try Baked Snack, it gets the best battery life for 2.1 ROMs.
http://www.bakedsnackshack.com/source/
Download Bakedsnack1.6 and Step 2.
Make a backup.
Wipe data/cache
Install 1.6
Boot the phone up
Reboot into clockwork
Install Step 2
Boot the phone up.
I have to have a car charger if I go anywhere. This phone dies so fast with normal usage. Do anything crazy like turn features on, surf the web, or increase brightness, and I am lucky to get 2 hours. I have multiple batteries, both have the same result.

2 Hours..? Whaaaaa? Lol.
When I calibrate my battery, I turn EVERYTHING on, screen brightness all the way up, Pandora running, every widget I can fit on my screens set to update at their quickest setting, screen set to 30min (Though I never let it shut off). Bluetooth, GPS, 4G running (I don't have 4G here, so it just keeps searching, which drains it more than if it was connected). And running the Maps Live wall paper to use GPS.
When I do all that, I can't get it to even die under 4 hours.
Hopefully you were exaggerating with saying 2 hours lol.
Thank you guys for replying!
Sh0wNuF: I killed the DRM service today and used ATK to kill errant processes throughout the day today to no avail. I also used the airplane mode toggle to try to limit my time without a signal.
SemiGamer: Thank you! I did do the clockwork step as I said in my first post, but I will try to install BakedSnack and get back to you guys as to the battery life.
From the looks of that juiceplotter graph, your data is constantly on and destroying your battery. What is the point of having juicedefender if the data is constantly on?
If you set up the phone properly, and there are a MILLION threads on this which state a MILLION times to disable DRM and toggle airplane mode as a mere baseline beginning, you should lose at most 1% an hour when the phone is idle without a data connection and the screen off.
Now it looks like you probably have the data on constantly with emails rolling in, facebook auto updating every 5 minutes, weather checking every half hour and other things that are just destroying your battery life. If you need your phone to do all that nonsense, then you will be crying for the rest of the time you have it.

Thank you for your reply, but as I said in my first post, I was using both JuiceDefender and Superpower to make sure data was off in the background, and as I said in my most recent post, I did disable the OmaDrm service as well as enable/disable Airplane Mode to lower my TWS.

Thats fine, but your data aint off. Look at that graph you posted. Every little blip is either data being accessed or the screen turning on. The line should be smooth if there is no data and no screen on.
So there are two options, either you are constantly using the phone and its the screen killing the battery, or you have juicedefender set up all wrong and its the data killing the battery.
If I remember correctly, any spike below the line is data, either wifi or 3g and any spike above the line is the screen turned on. So from the looks of it your data is literally never turning off and you are checking the phone and turning the screen on and off pretty frequently.
What are your settings in juicedefender?

I have almost identical batter results as you. I do use the phone fairly often to send messages but the screen brightness is all the way down and I use set cpu on the froyo beta leak. I reset battery stats and also (perhaps you could look into this too) checked spare parts for any rogue programs. Does yours say the screen takes up most of your battery even if you barely use it?

I would up the Schedule to less often and turn off the traffic toggle. Also, I wouldn't doubt that your phone is never going to sleep. If you have spare parts check the Battery History. If you listen to music with the phone, the service started by the music player, CorePlayerService, keeps the phone awake constantly for me. I ended up making a simple kill music widget using tasker to fix this issue.
I bought a wildly overpriced Samsung stand/battery charger from Amazon. My wife & I each start the day with a charged Epic and a spare battery. No worries

When you say much better battery life exactly how much? My battery dropped 20% today while not being used and Display was still at 60% (I turned the alarm off twice). I'm running the Quantum ROM which could have something to do with it but the battery is horrible for me. I can't get more than 8 hours and that's if i barely use it. I have spare parts and no apps are partially waking it. Just Wifi and sync. No GPS, brightness all the way down. The main thing that bothers me is that display is always #1 even if i don't use the phone at all. Any thoughts?
I've ran both Quantum and Viper Froyo roms and aside from making my phone hot enough to fry eggs, the battery life was not good.
As far as battery life goes, I'll start with the obvious stuff.
1. Turn off GPS, Bluetooth and 4G. 4G is a complete power whore.
2. As for wifi, turn it off unless you are in a bad coverage area for cell data. If you are connect to wifi and set Spare Parts to never let wifi sleep.
3. For DRM there are 3 files you need to remove that will prevent it from running / reinstalling and they are DrmProvider.apk, DrmUA.apk, and SisoDrmProvider.apk.
4. Toggle airplane mode every single time you reboot without fail.
For a true test of whether your phone simply needs to be returned as "defective" you should wipe the device, dont setup a google account and let it run for a day after executing steps 1-4 above. It would be best to an apk for Spare Parts and SDX Stock App Remover on your microSD that could be installed using My Files. If you still have problems take the phone back to sprint (after restoring it to factory of course) and tell them it is defective.

Here's a JuicePlotter graph from today for comparison from my original one yesterday.
I still wonder if it wasn't going to sleep because of PowerAMP and I didn't underclock today like I did yesterday.
There are a few other physical issues with my phone (slider seems a bit loose compared to my other phones: if I swipe with slider closed with a bit more pressure than usual, I can feel the screen move up and down; screen seems to slightly come up a bit when phone's tilted a bit, taps make you feel the screen go back down) that also made me want to consider exchanging it on top of the battery issue but if I'm getting good battery life I don't think I'll mess with what works, unless anything gets worse.

Really Bad Battery Problem. Help.

past 2-4 days.... my nexus just dies suddenly with the battery drained. checking history with system panel shows that the cpu usage just suddenly shoots up to 100%! and i dont know what app is causing it.
just updated locale and extended controls + a lot of other apps. but my main main suspects are locale and extended controls (since EC posted that they are having problems with the update on the nexus)
any ideas? any other apps i could use to target and isolate the rogue app that drains my battery?
get a task manager and see ?
also, it may just be time for a new battery. ebay. $13 shipped, 2400 mah

System Panel HAS a history, and you can see which apps are using CPU, so have you done that? Is the phone getting hot? It would if the CPU was running 100%. And even at that, it wouldn't immediately die, I've never exactly tried to see how long 100% cpu utilization takes to drain the battery but I'd have to guess it's at least 2-3 hours.

seems fine at first then when i notice its hot... it is already about to restart. couldnt even get to check the app usage on system panel. after reboot... the app usage in system panel goes away. just checked now.. nothing is eating the battery up according to system panel.
guess the rogue app just turns on and eats up all the juice at some point in time. weird.

Do you have SetCPU or anything else enabled with a performance-oriented governor or similar? That would likely keep the CPU pegged at the max without really doing anything.
Try disabling as many applications as you can until you can pinpoint which one is misbehaving.
Same Problem Here
My phone is experiencing atrocious battery life, and so is a friend of mine's. We are both on FRG83D, and it seems to have been the trigger for the problem. He is on AT&T and I am on T-Mo. My wife also has an N1 on FRG83D on T-Mo, but her phone is not having the problem. Her phone is set up very Vanilla, my friend and I have more system altering stuff on ours but nothing too wild, and none of the phones have ever been rooted. The two problem phones both use Launcher Pro and Extended Controls, I am not sure what else we have in common in our apps. I installed System Panel today to try and figure out what is happening, but I still can't find an obvious culprit. While the phone is sitting on the dock charging the CPU seems to be idling under 10% and when I pock it up and look at System Panel you can watch the CPU spike to the upper ranges if you scroll the screen but otherwise it is idling under 10%. The display is always the highest on battery usage and the worst app shows as System Panel, but that is basically what I expect to see. I am ready to start removing apps to see if I can get it back to normal unless anyone has an idea of how to better diagnose the issue.
I had this issue a while ago. "system" was taking up all my CPU, and I couldn't find any details about what was really causing the problem. I couldn't remember how I finally found out about the problem (I think I spent a night reading the logcat to see what was wrong). I couldn't even use the phone, it became horribly sluggish, and battery went flat in mere hours. Turns out, I had a bad picture or two in my SD Card, and the media indexer went in a loop trying to interpret the files. For some weird reasons, the same files got Windows Explorer "confused" too.
Try to remove or format your SD card and see if it's doing the same. I know it's more of an anecdote than a real known issue, but it won't hurt trying
oh wow i was hoping someone was having the same problem... left it overnight unplugged so far so good. now im really beginning to think its extended controls. took out the widget and replaced it with the stock one for now.
IDLING at 10% CPU usage??? Mine idle at 0% if nothing is active. Average 3% over time.
You guys should watch and see what's using hte most CPU, SystemPanel can do it if you look at the history (free for a week or 10 days or something, or buy it to keep the function), but also look at Spare Parts, you can install it from the market. It gives you visibility to a few more Android settings/info menus which you can see which apps are keeping the system awake etc, it can help pinpoint what's going on.
Something very bad is happening. When you all figure it out, report back.
When I look at system panel the little CPU circle graph stays at 100% for the most part. I don't understand if its accurate.

Do you have the app 'Extended Control' installed? The last update is very buggy and is causing bad battery life and broke the camera app on the N1. Check comments on the market. They are working on a fix.

Looks like Extended Controls
I did some testing and Extended Controls does appear to be the culprit. Dev seems to be aware, hopefully they get it sorted.
Edit-Overnight and battery life is back to normal with Extended Controls uninstalled. I didn't suspect it at first because they had already released an update after FRG83D, but apparently it was broken worse than they knew. I hope they fix it soon, I like the app.

It obviously should not sit at 100%, look and see what app is using CPU, it ain't rocket science.. Mine idles around 3% with my apps, mainly K9 and Tasker, weather etc..
Step 1: Call HTC's exclusive Nexus One Phone number
1-888-216-4736
Step 2: Tell the rep your battery isn't holding charge. (Possibly tell him your earphones blew as well, if you lost them like I did )
Step 3: Wait 3 days for the battery (and headphones?) to make it to your door.
You don't even have to ship your old battery back!
Step 4: ???

Battery draining problems

Hiya,
Ever since I got my phone replacement (Brand New in Box from Bell) I noticed that the battery drains 10% per hour regardless of my current clock speeds.
I'm only listening my music.
My mobile data is on.
Wifi is off.
I have ES Task Manager set to autokill when screen off
Details:
ROM- CyanogenMod Nightly #140
CPU Clock speeds- 245~368 Mhz
CPU Governer- ON DEMAND
VM Heap Size- 48m
Sent from my HTC Vision using XDA App
Just making sure I'm reading you right, you have es task manager killing apps? Android 2.2 doesn't have any need for that, and it may hurt your battery life.
First thing to check is to make sure any apps that sync (weather) aren't syncing every 15min, and change them to every few hours. If that still doesn't work, try a different battery. May just have a bad one.

Go into spare parts > battery history > partial wake usage
This will show apps that are running in the background that are using the battery. If there are any 'rogue' apps that aren't behaving properly, this should show it. You can also use Watchdog Lite from the Market (free) to monitor CPU usage of applications to try and find what is running down your battery.
Although, if you are listening to music, 10% drain per hour doesn't sound too much out of the ordinary.
Update: I stopped my music for roughly 45 minutes and it seems that music doesn't affect it much. It still drains.

Yea good call. And get rid of that task killer! No need for that, especially in CM7.
Having similar problems suddenly. I was getting nearly 24 hours of battery life with normal usage, but in the last 4-5 days the phone drains to death while in standby. Searched here and online and couldn't find anything other than the normal check apps, etc. But I haven't changed anything in months, and usage isn't showing anything out of the ordinary.
Is it possible my battery is hosed? Android OS says battery health is still "good", and outside of screen-off it seems to drain normally. I even left it on for about 30 minutes and lost 1%. But overnight it went from 100% to 1% in just short of 7 hours with absolutely no use. So bizarre...

It's not just you.
I have same problem, with two different batteries, even after hard reset.
I have been having this problem the last two days as well. The t-mobile forum says to roll back the updates to the google maps app. I just rolled it back, will see if it helps.

Didn't help me.
Only turning on airplane mode helped me.
I think it's a TMO infrastructure/network problem of some sort, honestly. Maybe a bug with the deployment of 2.3?
Yeah didn't help me either.
I had my phone fully charged when i made the post earlier and it is now dead.
Hopefully they shed some light on this soon.
OK good I'm not crazy
One thing I noticed last night after draining and wiping battery stats again is when I woke up it said Dialer took up 49% of the battery usage? I charged to full with the phone off, turned it on and it sat on the nightstand until this morning. Received 2 texts during that time, no phone calls made or received, and my alarm is set at 6am on it and went off. Battery went from 100% to 19% in this state.
This is frustrating. I read the T-Mo thread and it's seeming more like network issues? Anyone else have this problem here on XDA?
EDIT: Customer Support is useless. Insistent that forum posts "mean nothing" and I need to pay them $20 to replace the phone. Also they have no logged issues on this, even though I've seen multiple posts of people who've called in. Sigh.
Also been experiencing the exact same problem with CM13X and CM151. I had uninstalled maps, which didn't improve anything, so I reinstalled it and it appears to be okay now
So far 1h16m since full charge after uninstalling Maps completely and rebooting and clearing cache, and battery is still 100% while sitting on my desk here at work. Also Dialer isn't showing 50% usage either. Hmmm.

Battery drain when powered off w/o dock

I've noticed that when I attempt to power on my Transformer a couple days after powering down that the battery is completely drained as if the device was never shut down. The only way to power on is by plugging in to an outlet. I was under the impression the battery would last longer than a few days when powered down.
It definitley should, if I just put my tablet in sleep and leave it all day, it loses about 1% per day, so turned off I'd expect the same or better.

Wow, mine loses about 10-15% overnight. The same as the op... The batch number is B50*****
Mine too drains battery when in sleep mode. Also B5 build...hope an OTA update will fix it soon and that it is not a hardware problem.
Same here and I'm stock w/out root...

Mine was in standby with airplane mode on (wifi off) - B3OK
100% battery was down to 64% by the morning. In 10 hours lost 36% battery
With all the talk about keyboard dock drain - I think this is more a important issue.
I have a B50 tablet, and mine only looses 1-2% per day if left in standby. This is in Airplane mode. Dunno what you guys are doing to loose half your charge over 24 hours.
Probably background apps. Some apps force load themselves (Like Thumbs keyboard and TapaTalk which wants to prevent standby on installation according to someone else on this forum).
I am also experiencing this issue. When I put the tablet on standby the battery continues to drain. When I when to sleep last night the battery was at 30%. When I turned it on this morning, it showed 4%!
This is unacceptable. The battery saving option is turned on. Is ASUS aware of this issue?
if you look at the battery info chart, does it show it becoming awake shortly after using it and staying awake for quite some time with the screen off?

B50 here. 0% battery drain. woke up and used it to check XDA for a little bit and went down to 98% but that's to be expected since most tablet/phones don't like to stay at 100% battery level to preserve it longer.
airplane mode while sleeping.

it would also be helpful for you guys to say what ROM / kernel you're using.. and if you're stock, say stock. hence why people on XDA have this stuff on their signatures
I am on stock. Could it be because I have some apps running that are causing this battery drain? Or is it the microSD card?

microSD wouldn't drain your battery. I would say check your battery usage but that's disabled on stock.
- Check your Google Accounts in Accounts & Sync. Is Picasa Web Gallery checked for syncing? I heard there was a bug about that and it consistently drained the battery even when you're not on Wi Fi.
- Any syncing apps, make the interval longer or make it a manual refresh if it's not important.
- There is a bug where the tablet may be trying to interact with Mobile Data. I'm not sure why but people on other Honeycomb tablets have reported the same thing. You can bypass this by activating Airplane mode. You can still use WiFi when it's in Airplane mode.
- I personally don't use any SetCPU profiles. They tend to do more harm than good. Just my opinion, it's up to you but if something's going wrong with your battery. Try disabling them and see if you notice a difference or not.
- My WiFi sleep policy is set to "when screen turns off." Even though I select this, my tablet still gives my notifications on emails and stuff. Seems to be working well for me.
- Don't use any task killers.
- If you use a kernel that supports undervolting. Play with the settings and undervolt. My kernel that I use doesn't support it but I still get good amounts of battery life.
- I don't overclock. This could drain your battery as well (unsure, but it probably does to a certain extent). At 1.0GHz my Transformer is fast and responsive so I don't OC anyway. I only OC for benchmarking for fun.
Many people have said to disable GPS. But in fact, GPS is on demand! Even though when it's enabled, GPS is only used when a app or the browser requests your location from GPS. I personally have it on, but it's up to you really.
There. I just compiled some battery tips. Hope they help.
A true way to find out if something is severely wrong is to put your tablet into Airplane mode while sleeping. When you wake up, check how much % you lost. If it's over 5-7%, I'd probably say something is wrong with your setup.
^OK thanks . I will give it a try when it is fully charged.

At least check if Picasa was syncing. If it was then that could of been the source of it. Let me know?

OK I have unchecked the following syncs:
- picasa
- calendar
- Skpe sync
I have also turned on airplane mode. Lets see what happens.
So how do you tell ???
How can you tell which model ( B30, B40, B50, B60 ) you have ????

It's the serial number. Check the sticker on the dock for S/N or on the box that it came in.
After making the changes I described in my last post, I am now losing about 2% every 4 hrs. That is 0.5% every hour on standby. Much better than before but I believe others here have a much lower battery discharge rate.
I will continue to monitor the battery discharge rate under different scenarios.

Same problem, if left overnight looses around 30-40% of charge and looses 3-4% as soon as I disconnect charger. All sync is of, email check is manual. Juice defender is installed and on. So I have checked its logs and it says that almost every 10 minutes tablet uses WiFi connection. Went to Settings of WiFi connection and unchecked Notice about open Wifi spots and checked Always on when cgarger plugged in instead of "Always on". Will see how it works now.

Terrible atrix battery

I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated
Edit : phone idle consumed 40% :O
I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot
Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

OP stated he tried calibration without success... I too am having subpar battery performance - interested to see what others have done to achieve better battery performance besides the previously mentioned methods.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...
New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...

I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.
Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.
The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same
When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.
How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.
i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.
I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.
When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)
After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I use the same battery settings recently. I turn off GPS and Sync unless I'm using navigation. Which blur apps do you freeze? I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.
