Sigh. My Evo's Battery Life is Rediculous (not typical)

Fully charged my phone night before last and went to work in the morning (9am). I didn't touch it all day, didn't even turn it on. On my drive home at 5pm it was dead, off.
I plugged it in with the phone off when I got home and saw that it was fully charged a few hours later around 10pm and I booted it up and left it alone. This morning it was dead, off.
Looking at the apps that take up my battery doesn't work because it doesn't retain information what happened to the phone prior to the last reboot. Not sure what to do. My awake time matches my standby time exactly. It's obviously a 100% awake time problem but what's triggering this?
I'm on Fresh .3 with absolutely no other mods. I don't think I have any apps that ping outside servers. So what the ****!?
EDIT:
lulz, I just realized I haven't been even able to use the phone in 3 days due to this issue

Something is eating your battery obviously.
Restore to stock and see if you have the same issues.

That's a PITA. This is a clean fresh .3 rom install with only logmein, dropbox and couple non-online games installed. Why is this phone such ****ing fail right now.

Have you removed the Favorites widget? Doing that stopped all battery drain problems for me. Just delete the widget.

First thing to check is if you have a sufficient cellular signal. If you are getting a weak signal it will cause poor battery life. If cell signal strength is not your problem then it is definitely something you have installed on it eating away at your battery. That said check/do the following:
1) Check how frequently you have your accounts syncing
2) Before the phone dies look in your battery use to see what's eating your battery
3) Install a task manager/killer (I use Advanced Task Killer)
4) You don't have to do this one but it does help. I use a program called Startup Auditor to disable startup on apps I don't need to run when the phone first boots (you'd be surprised how many are in there).

delete it completely or remove it from one of the home panels?

the "time without signal" workarounds seem to prove the most effective for me. in addition, reduce background usage and automatic update frequencies as best as you can.
according to this thread [http://forum.xda-developers.com/showthread.php?t=709768] (and link within), HTC has acknowledged some issues and is preparing to deploy a few fixes.

You are running someone else's ROM, there could be a problem with the radio, or a problem with the way it was loaded.
If you are in an area where you don't get signal, you are going to drain the battery, and FAST.
Do you have 4g on but not in a 4g area?

I am...
fully rooted and have fresh .3 as well. I am getting over 30hrs with moderate use and the last hour of that I had everything on to purposely run it down to dead. (was doing a toastch recommeded battery meter calibration).
Took my phone off the charger last night at 7:30 pm. It's 2:23pm and I have 31% left. I have Wifi, BT, and Background apps with auto sync turned on.
I would say you might be experiencing the Motorola cell tower problem. HTC has confirmed that the EVO is not playing well with cell towers that have motorola transmitters. It is causing the phone to use more energy to dial in the tower.
To be sure...
1. Set all apps and widgets to manual update or update once a day.
2. Get rid of the people app or widget from any home screen.
3. Go into Gtalk and uncheck auto sign in. Then sign out when you exit the program.
4. charge the phone until the green light comes on. Don't use a battery meter. The second the green light comes on, go into recovery and wipe the battery stats. Reboot the phone and run it until the battery dies and will not longer power the phone. This does nothing for the battery but does recalibrate the internal battery meter.
5. For maximum life...turn off: background data, WiFi, BT, and Mobile networks when not using. keep screen at 1/2 brightness.
If I do the above and manually update mail, weather, social apps, etc... and only turn radios on when I need them, I can get 40 hrs. out of my EVO and this is under moderate to high moderate use.
One other thing....plug your phone in for 10 minutes. Then unplug it and go into immediate stand by for like 30 minutes. Go to settings>about phone>battery>battery use>cell standby. Time without signal should be very low....anything over 10-15% and I'd suspect that if you did everything in 1-5, you have a towers issue robbing your battery.

I was having awake time issues with Fresh .3, so I switched to DamageControl, and everything has been great. Unplugged this morning at 7, and I still have 75% battery remaining. Better battery life than the Hero or BlackBerry Tour!

I seem to be having the same problem as you and it is quite frustrating. I get a steady 10% battery drain every hour even when its idle. I tried juice defender and setcpu and it is still the same. I turned off all my sync accounts and nothing. I also have systempanel and it doesn't seem like theres a rogue app eating my batteries.I'm going to truth to stock tonight to see if something is wrong with my phone. Did you ever figure out what was wrong with your phone?

AVA9 i get 20 hours a charge
but YES something is eating your battery install system pan have and let it run a bit and check the info id bet its
1 your evo spend a lot of tWOS
2 you have a rogue app eating your battery

Way to bump an ancient thread.

DOH dear god i did not look at that lol

I do apologize for bumping such an old thread, but I feel like this thread has already asked much of what I also wanted to ask but have not reached a conclusion. Therefore I would like to try and solve the problem or provide as much info as I can to solve the problem.
I indeed have installed systempanel and here are the screenshots for the day.

(sorry my account is not allowed to post links)
As you can see besides the internet, there is nothing else thats taking up the battery. Also I took this pic after I put the phone on the charger for a bit, it was at ~ 13% before. The battery usage information says a majority of the battery was used by #1 android system and #2 cell standby, it was neck and neck almost, with #3 being phone idle. My weather app polls every 3 hours, my facebook syncs every 30 mins, my htc sense facebook syncs once a day, and I have not configured any other emails except for two gmail acconts, which received probably 3 emails throughout the whole day.
I just used setcpu today, it made absolutely no difference. Same results as yesterday when I did not have setcpu. Thanks in advance for the help!

dude you need to try my setup: superevo and setcpu
i got 7 days of battery using the evo as a simple phone.

Why would anyone use an EVO as a simple phone.
I am beginning to think peoples opinions on moderate use vary tooooo much. The EVO is similar to an unplugged laptop. The more you make the cpu work the faster your battery is going to drain.
It seems some people just dont get that.

[Battery Stats] I didn't bring my phone to work today

I had everything turned off. No email, no sync, no wifi, no gps, nothing. I fully charged the battery and unplugged it before I left. Display was never turned on. I wanted to see a completely isolated battery test. The only applications I had active according to my task manager was Launcher Pro.
Time on 10 hours 20 minutes
Battery life left 60%
Battery used 40%
Cell Standby - 40%
Phone Idle - 30%
Android System 20%
Calls (1 missed call) 5%
Display 3%
Maps 2% (Why does maps show up?)
Again this is with absolutely 0 use or syncing going on. Left phone at home, turned on and immediately checked stats when I got back from work.
According to this small test I can't even last a day on a full charge even if I left it completely alone.
Thoughts?

In 1.5 day of standby with every radio off and no sim, my phone only lost about 5% with stock JI6.

I think it is a cool idea. I find that 5% usage for one missed call is very bad. I have really suspected that voice calls kill this battery and that seems to add evidence. 5% for a missed call? That is messed up.

I think this is the aspect of battery life that doesn't get addressed enough: drain during standby. Of course everyone expects to lose some power while the display is on and syncing/other processes are running--but what about when the phone is left untouched? Here are 3 ideas:
3g is a notorious battery drain even when the phone is not being used--use 2g instead.
Freeze or uninstall media hub and other running processes that attempt to run/connect to servers in the background. I removed dmservice, media hub, and all drm processes and this seemed to be helpful.
Use a custom rom--these appear to hold power in standby better than stock roms do.

Cell Standby indicates that there is an activity that polls something from the network.
if you are so concerned about what it might be, you can see when and how much data is being used by going to your TMO account online and check for the data usage - one of the good features TMO put in place is actually tell you when your phone connected to get what amount of data over the data connection, does not tell you what it was doing though.

Yeah, something is going very wrong in your phone. When my phone is on standby with just 2G on it drains less than 1% per hour. I would definitely recommend getting rid of the drm service and media hub (and Daily Briefing). I also use Autostarts to keep all kinds of random programs from starting at inappropriate times (Really Slacker, does your app need to launch every time the time zone changes?)

According to Samsung the phone should last 450 hours in standby mode...

I wonder if Samsung's definition of "standby mode" is what the rest of us call "off".

I've never had any kind of batt life with this phone...charge everday overnight...start work at 8, use here and there for navi (around 10 mins max, maybe 2x a day) about 30 min avg talk...and mp3 player...get home by 4 and always at 30% or (most often ) less...have had stock/ bionix roms, never changed, no matter what build....it's pathetic..called tmo, they said there are no known issues with batt on this phone...wow...do a google search on it..anyways, they are sending out a new batt..I hope I just got a bad one...seems very random tho, some ppl have all radios on ,screen all the way up and get 10+ hrs...if i left my screen on (say navi on) for more then an hour straight I'd be out of battery..very weird..praying new batt is better...

Does it seem like youre just not getting the battery life you should from your phone? Do all your other friends keep going while you slowly putter into a shutdown? Well pout no more! Simply follow these steps to clear your batter information from the phone and your phone will act better then new! :)
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot to normal
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"

I turned my phone off today. Then I left the house. When I got back the battery was glad to see me. Seriously, I've read just about everyone and almost started my own battery disturbance thread. I've come up with a new thought at least for me. I don't care any more. I have electricity. I have a spare battery and a charger. If my phone wants to last a whole day. Yay! If I use it more because of some game with angry birds or cards or dice, great. I've reached that Mark Twain moment somewhat tweaked when he said,
“Age is an issue of mind over matter. If you don't mind, it doesn't matter.”
I'll tweak it with the last 27% of battery left in my feeble vibrant to:
"battery is an issue of mind over matter. If you don't mind, it won't matter".
Enough already I say! Lets spare the air. Batteries are meant to be used
Back to the regular reading of all the battery threads now.

I think I had the same issue as you. Cell standby was the biggest drain. When you tap on that, do you see 50% time without signal? If that's the case, this seems to be a bug in Android which was somehow introduced in JI6. The best solution I've found so far is after every boot to put your phone in flight mode for a few seconds and back. This fixes the radio glitch, your time without signal should go down way under 50%, and battery drain should stop. Hope that helps.

You should recondition your battery:
Fully charge
Reboot into recovery wipe battery information
Reboot into OS
Unplug power cable
Let battery FULLY drain (do not plug in until fully dead)
FULLY charge battery (do not unplug until fully charged)
This reconditioning should be done after every ROM flash.

Answers on battery life.

I've been seeing a lot of posts on crap battery life around here, and I was chasing my tail about some of them as well, following a lot of misinformation even by senior members. I think I have a good handle on it now, and picked up most of these tips from these forums, so I'm not taking credit for these ideas, just collecting them in one place. Some of my suggestions assume you have root and Rom Manager (see the Tips and Tricks sticky thread on how to get them).
1. If your battery drains in less than a day on standby, you probably have a bad flash of the JI6 modem (either from the OTA update or from a ROM). Flash the JI2 modem from here "www dot teamwhiskey dot com/home/downloads". If the flash fixes it, you may try going back to JI6 if you want, and it may stay fixed. I went back to JI2 and didn't bother going back to JI6, but it has worked for others. With JI2 and 3G on I get just over 24 hours in normal usage.
2. The #2 battery drain on standby is 3G. I turned it off (Settings/Wireless/Mobile networks/Network mode/GSM only) and my phone lasted for 40 hours on Edge with light usage (few phone calls, messaging, quite a lot of web surfing, 2 hours of podcasts). Didn't even feel too slow (I get 140kbps on edge). Can anybody suggest a really good widget for turning 3G on/off? I use the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.
2.5. WiFi always on is a huge battery saver! It keeps 3g off. I can easily get 3+ days with light usage on my home wifi. Settings/Wireless and Network/Wifi Settings/Menu/Advanced/Wifi Sleep Policy/Never.
3. Don't need a task killer. I wasted all my time killing tasks trying to chase down my crappy battery usage, but since I fixed my modem and turned off 3G I know that the 3-5% CPU usage at idle does not hurt my battery. Taskiller for me was actually hitting the CPU constantly, lightly but for no reason, so I got pissed and uninstalled it.
4. Install a CPU usage monitor like Usage Timelines. It sits in the notification bar, very easy on the battery, but tells you if you have a rogue app pegging your CPU and draining your battery. These are the only apps you should be worried about killing. Astro File Manager has a task manager that shows CPU usage for each app, so you can kill the rogue one. I shoot for about 5% cpu usage at idle (at 200mhz - at 100mhz it would be a bit higher).
5. The app Autostarts lets you disable any app from starting on boot or other events like connectivity changes. This is not strictly necessary unless you have a lot of crap apps installed on your phone and they like to start themselves and waste CPU time behind your back.
6. If your battery reads less than 100% as soon as you unplug it from the charger fully charged, or your battery meter sits at 100% for a long time after you unplug it, you can recalibrate your battery meter. To recalibrate: 1) charge your battery to full, 2) unplug, 3) reboot into Clockwork Recovery and 4) Wipe battery stats.
7. There is No Such Thing as "battery reconditioning" (for all intents and purposes). The above procedure only RECALIBRATES you battery METER to read on a more linear scale between full and empty. It DOES NOT make your battery last longer, period. Whoever tells you that is a moron. If your battery is dying in 6 hours, doing any amount of calibration will not make it last longer (I've tried).
8. I wouldn't be too worried about undervolting, overclocking, kernel tricks and superawesomefast ROMS. The CPU drain at idle is so minuscule (as long as you don't have rogue apps) that those things make precious little difference. Like I said, the biggest drain is 3G and other radios. Having said that, I run Bionix 1.9 with the JAC kernel. It drained my battery in half a day at idle until I flashed the JI2 modem. With JI2 it suddenly started lasting over 24 hours, and once I turned off 3G, over 40 hours. I like this ROM and see no need to switch, it's very smooth. But you should be able to get similar battery life on a stock Vibrant.
9. I have GPS on, WiFi never sleep, auto-brightness, and a few widgets on like Weather and friend updates. I have no fancy settings, literally just turning off 3G (or wifi on, which is the same) got me 2-3 days. So I wouldn't waste time fooling around with magic settings (other than wifi never sleep), battery saver apps, etc.
10. If your screen is on all the time and you're playing games nonstop, you're draining your battery quicker than any of the things I mentioned above, so you probably don't care. In that case an optimized ROM/kernel is probably your best bet, especially JIT in Froyo. You can probably save on screen brightness as well.
If you guys have any other tips I'd be glad to add them to the list, but I hope this gives you an understanding of where your battery life is going. Basically: bad modem, 3G, or rogue apps.
Also, I hope this will put an end to trolls calling people whiners for complaining about battery life and saying unproductive **** like "you're a whiner" or "the Galaxy S is just a battery hog, live with it". It's not, you don't have to live with it, nobody should have to, here are your solutions.
Good luck.

A few things I do to help with battery life is:
Disable Audible touch tones
Disable Audible selection
Disable Haptic feedback
Disable SD card notifications
Set animations to NO animations
Uninstall media hub if you dont use it
Disable auto brightness adjustment
Disable power saving mode
I disable the last 2 and just swipe the notification bar to adjust brightness. Granted these items really only work when using the phone but I can go about 2 days of normal use without a charge believe it or not.

yeah disabling 3g has always been the best option for people really, really concerned with battery life.
But it's kinda hard to tell people not to use 3g on their brand new 3g capable devices.

You may want to add how to test if you battery is bad. If you use you phone repeatedly while it its plugged in you risk overheating and damaging your battery. Signs that unitas is the case are very quick drain and long (7 hours) charge times. You can easily test and see if your battery its damaged. Remove it from your phone and place on flat surface (e.g. Counter top) try spinning the battery. If it rotates easily and quickly you battery is bulging, this is a sign of damage. Time for a new battery.

Use APNDroid. Comes with a widget.

Thanks to the OP and other contributors in this thread.
I flashed a ROM with the ji6 modem and battery life has been noticeably ****ty since. Example - this morning I unplugged my phone at 7:30 am. 100% charged. It's 10:21 am and my phone is at 75%
In the last 3 hours I browsed the web for 10 minutes while having my coffee and a smoke before heading out to work. Blue tooth was on for my drive, and I've sent 2 text messages. Aside from that my phone has been on stand-by since I unplugged it 3 hours ago.
I'm going to try to flash back to ji2 tonight as the battery usage was definitely better. Will also look into the 3G thing.
Thanks again.

You forgot to mention the two DRM and one downloader services that run resident on JI6.
These were the cause of my reduced battery life after I upgraded. Killing & removing these processes restored my battery life back to normal

I just tried this - switching 3G off works fine, but switching 3G back on didn't work for me. I had to re-boot to get 3G back so this is a no-go in my case.

I know how to kill the processes for the DRM and downloader but how do I remove them?

OP thank you for putting together the list. But I've never seen the point of doing all this. Its like getting a lamborghini and only driving 40mph because it you don't want to waste gas, whats the point? Either get a second wall charger to charge at work or a car charger. Heck even get a second battery if you are out for a long period of time.

You don't need to disable 3g.
The point of my post is to avoid people wasting their time with tweaks that have little to no effect on battery life. I'm telling people that they're wasting time killing apps and optimizing cpu usage and twiddling their settings when the radio drains most of their battery on standby anyway.
Meaning no matter what changes you make, you can only hope to improve your battery life by a tiny amount, because any other effect is overshadowed by 3G.
Put another way, you will NEVER get battery life much longer than a day if you're on 3g, so you're wasting your energy trying all kinds of tricks.

For me the widget did nothing. But it seems like it's not even supposed to turn the 3G radio off, but ALL APN network traffic. Did I miss something? It won't save battery power as long as the 3G radio is on.
I went back to the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.

While i understand the idea behind this thread, your conclusion is simple.
If you use the phone as a smartphone, it will eat up your battery no matter what.
I personally go through two batteries and some a day. (they cost about 12 bucks in ebay, and they work just fine)
The price for saving battery is not using the phone, and having a 400 bucks phone just for show off is just silly at least.
If you have a phone like this is to use it. At least you can change the battery not like some other devices......

I understand that task killer is useless, but do any of you use Autokiller (memory manager) ?

That's kind of a redundant question because even if you do not use the app, your phone is still performing the functions. The app just adjusts the settings. But to answer your question, using a memory optimization tool such as AutoKiller is 1000% more efficient than using a Task Killer. I don't think it effects battery much, but works wonders on performance.

There's no 3g-off widget because apparently in Android there's no way to do that through a direct command. I also use the Curvefish widget, and you are absolutely right about turning off 3g to save battery. I normally do so when I'm asleep or if I'm sitting at my desk next to a computer (why do I need fast data on my phone when I have my computer right here?).
The other thing I would recommend is AutoStarts. There are way too many apps that open themselves up at bizarre and inappropriate times. Autostarts is an easy and painless way to see which apps do this and keep them from opening.

Great battery life comes to people who hardly use their phones. Guess I need to get a netbook. Will prolly get a netbook or 3g laptop + skype and ETF my phone soon. These battery woes are show-stopping.

Losing 4% an hour on standby when you're not using the phone is unacceptable. Samsung screwed something up with the JI6 update. Most people think it's because of the stupid Media Hub. I think they are right.
People are not complaining about the poor battery life from using the phone. They are complaining about the slow battery drain even when they are not using it. ~4% an hour adds up fast. Vibrant is supposed to have 450 hour (18 days) stand-by time. That's what is rated. But people are getting 24 hour (1 day) stand-by time after JI6.

I'm not ready to sign off on this idea. For me simply flashing JI2 over JI6 fixed it. For some people flashing JI6 back over still left the problem fixed. I still have those processes running on JI2 and my battery life is fine.
The other reason I'm not ready to recommend wiping out those DRM processes is that apparently it stops the bundled Avatar movie from playing, and might affect other things that users may get pissed about. I've read that killing the downloader process people are talking about kills the market. So I really wish those people advocating that solution would figure their **** out and provide exact steps for the fix (right now their posts are really vague like "kill the processes that are named something like this" and not well tested; in all my research I didn't find the exact name of the "downloader" process).

Is it possible to flash the ji2 modem without root? Wishful thinking, I suppose..

Insane Battery Drain...Please help

This is my first android phone and I'm wondering if I am doing anything wrong. Yesterday I charged my phone and it was at 83%. I unplugged the phone and went to sleep, when I woke up this morning the battery was completely drained.
This happens a lot. Even if I am not doing anything it still drains like crazy. I just text, make some phone calls and it barely makes it through the day. I don't play any games, no gps, no Bluetooth or anything. With my plan, I don't have a data connection so I can't connect to 3g/4g so that shouldn't drain anything.
What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

If you cant connect to 3g/4g, you should turn it off in settings. Otherwise, Your phone will constantly look for a signal, draining your battery.

Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.

The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:

Good luck...I had both of the problems and my phone didn't last to dinner time. Now I get better battery life than the iphone 3GS I had before this...about a day and a half of moderate use.
EDIT: also you'll probably want to go to settings>wireless & networks>uncheck "mobile network" since you don't have a data plan. No reason to have that on since you don't have a data plan.

I installed this using the Moderate setting, and then selected those options as recommended in preferences.
Does Watchdog use a lot of system resources when running in this manner? Will it cause the battery to drain noticeably faster?

Completely unnoticeable, IMO.

I installed watchdog lite and I have had couple of alerts. I got suspended couple of times and I also got Android system once.
Android system - 50.1%
Foreground
Suspend - 54.4%
Linux Process
I turned off the data usage from the settings and it did help save battery. The display is not using so much battery life anymore. It went from using 70% to 35%.
Edit: Battsatt reported that the battery was at 93%. When I saw the two alerts above I rebooted the phone and Battsatt now starts reporting the phone is fully charged.

Make sure the GPS is turned Off, too...

All these answers and the easy ones were not mentioned..
Make sure you shut your AUTO SYNC off...
Make sure you lower your brightneess....
Make sure you turn off GPS(was stated above me)
Turn off your wifi if you are not using it.. make sure you are not transmitting your hot spot stuff...

You just summed it up right there. You are experiencing the 'suspend' issue, period. There is no app you can install to fix it. There is no app you can uninstall to fix it. There is no setting you can adjust to fix it. There is no fix for the 'suspend' issue, literally.
I started the following thread in an attempt to consolidate posts and hopefully work toward flushing out what the real issue is...
http://forum.xda-developers.com/showthread.php?t=872839
This is a real, legitimate issue with Android 2.2.x Froyo. As I linked in my post, this is Issue # 11126 on Google Code...
http://code.google.com/p/android/issues/detail?id=11126
If there was an app or setting that fixed the 'suspend' issue, we wouldn't even be discussing this right now. There are fixes/workarounds for a lot of things, but right now, the 'suspend' process issue truly is a mystery. No one, not a single person has yet to post, "this is the cause of the issue," let alone a fix for it.
I wish you had a fix man, I really do. My fiancee experiences this and there's only one way she's found to sort of workaround it, sort of - she reboots her phone every morning. This seems to keep it at bay, at least more so than when she doesn't reboot each morning, once she takes it off the charger. She still gets it though and she's just used to looking for Watchdog and checking her processes now.
This thread could go on and on forever but it comes down to this:
- The MT4G does not have insane battery drain and will give you about 12 hours of life, under normal>medium usage. If your battery is draining insanely quickly AND if you're seeing the suspend process jacked up so high, then there.is.no.fix.yet.
There might be a ton of other replies after this about uninstall this, install that, change this, don't use widgets, use widgets, etc. Those attempts will be futile.

Exhausted every effort trying to fix this problem.. ATRIX 4G: new battery time?

I'll post everything I've tried and everything that's gone wrong here.
So initially I purchased this phone off of a friend nearly brand new, the screen had broken and had been replaced. Otherwise the phone is in perfect factory condition.
I unlocked the phone, and am using it on Rogers. APN settings working perfectly.
I installed GOLauncherEX on the phone as Motoblur wasn't doing it for me.
Battery life was crap (lasting hardly 3 hours and dying while I sleep). I found that Motoblur HOME had been running alongside GOLauncherEX. At first I simply uninstalled the third-party launcher, but then opted to grab LauncherPro+ and HomeSwitcher. This dramatically improved battery life.
Lately, I've been having issues once in awhile again. Mostly if I leave the phone unplugged while I'm sleeping (fully charged when unplugged) and we'll use the timeline 3am - 11am. It would either die completely or drop to around 15%.
As long as I could have enough charge to last me through work, I was fine with this as it was way better than what had been happening before.
This morning something extreme and unexplainable happened.. and it's the first time I took a look at the battery usage meter to see what had happened. Picture is below.
If someone could offer some tips or help that would benefit me even the slightest, it would be very much appreciated.
My bad for sneaking a link in, but it was the only way to show the issue.

Oh and also, phone is rooted, bloatware is frozen via Titanium Backup Pro.

Have you recalibrated?

Do you have any suggestions as to what to use to calibrate?
I'm not keen on flashing any new roms if that makes a difference.

Calibrating is something you may need to do after flashing a ROM, you can search and find a guide or you can use this app.

I have not flashed any new roms and I don't intend on doing so, but I'll check out the app you posted.
Thanks for your help,
any new ideas are still welcome.

The benefits of battery calibration are not limited to only if you flash a new ROM. Battery calibration should be the first thing you try if you are experiencing battery troubles imo, and there is allot more in depth information in the guides you could search for.
There is one more thing I can think of you can try, download Watchdog and see if there are any malicious or poorly written apps burning up your cpu/battery.

Thanks for your help, grabbing Watchdog now.

Maybe unlock the bootloader and flash a custom rom?

Go into account and sync and shut off background data. I was getting. 10-12 hours battery life and now over 30 by just doing that. Worked for a buddy at work too.
Sent from my MB860 using XDA App

Radio is key. After I flashed radio 1.77.30p, my phone can easily using 3 days without freeze anything.

Do not use 1.97 radio and don't use task killers. 2.3.4 gingerbread does a much better job of killing tasks than Froyo did and it's unnecessary. Also, turning off background data is not necessary.

I would say it is. Apps including google will try and update and locate your phone via 3g and gps when its sitting there idle. Its not necessary if you only install apps that dont use background data, or disable them individually but some dont allow it.
I still was able to get 15 hours with data enabled and over 30 with it disabled. There is a huge difference there. I just have to open my yahoo now to update it which I dont mind.

While I appreciate everyone's replies and help, has anyone actually looked at the picture I posted?
As much as I am most definitely interested in prolonging my battery life, that picture is showing a sudden drop from 70% to completely dead, idling, screen off, while I'm asleep.

I would purchase a new battery from Motorola, It looks like your battery has one or more bad cells in it. Only thing that really explains it. Even with everything turned ON as far as data - the battery should not drop that far that fast.

i'm not entirely sure whats going on with the charge level dropping so sharply. Either something is draining your battery big time or the readout when it says 100% is incorrect.
I had issues with the battery up time as well. In my case, the battery wouldnt last more than 8-9 hours. I had to charge it two times a day. Once overnight so its 100% when i go to work and again as soon as i get home. If i charged to 100%, unplugged and went to bed, it would be at 15-20% when i woke up.
The last time i went abroad, i left the radio turned off completely. I noticed that the battery held its charge for about a day and a half.
Now i did root, unlock the BL and install CM7 on my phone. It seemed better but not that much. After i setup the phone to NOT use my 3G data connection while my wifi was on, i noticed that i was getting great battery life when i was at home but still rubbish at work.
I'm doing a test right now to see if this makes a difference or not. I have turned off data on my phone all together this morning. I charged it to 100%. Normally after 6 hours at work, my phone is at about 30-35%
Right now its sitting at 75%
the 3g is whats killing the battery, on my phone anyway. I will see how long the battery lasts without turning on my data at all. Then i will compare that with how its like with background data turned off.
I would suggest you try re-calibrating your phone's battery, i use battery calibration from the market. Then either turn data off altogether like i have or just turn background data off as the others have suggested and see what kind of a difference it makes.
While i realize you dont want to, it may help further to have a ROM like CM7 installed as it wont have all the bloatware that can further reduce the performance of your phone. You should definitely give turning the data off a go to see its the culprit before you go spend money on a new battery which may or may not fix the problem.
Best to isolate the root cause before you spend money on fixing it. If turning off the data doesnt do it, then you very well may have a battery problem.

I'll definitely try everything you've mentioned, I did calibrate my battery since I first started this topic. I'm not sure if there's a difference, if there is, it isn't noticeable. My phone died last night, and I charged it overnight again so I haven't had a chance to see if what happened the other night will happen again. Soon enough, I'll post details if I notice anything peculiar.

Since you said you bought the phone off a friend I would like to make sure you have the right battery.
The battery "must" be of the following to show the right charge level, otherwise it might appear the battery discharging very quickly.
The part/model no.: SNN5893A
Manufacturing Date: ??/April/2011 or onwards

In regards to the poster above who mentioned shutting off background data, my phone lasts 17-19 hours running CM7 with nothing frozen, background data on, and I record quite a bit of video + pictures every day. I don't use task killers either. So I'm thinking that maybe the background data thing is either actually covering up a radio problem, a carrier issue, previous ROM information leaking through, or a faulty battery as stated above that could possibly need replaced.
