Honestly the battery life on this is not good for me, with no use but about one call I get 10-11 hours tops. With constant use(essentially not stopping for sleep mode)browsing and just going to apps like xda and the market I get about 4, back on stock 2.1 before the JI6 update I could go days on standby. I've wiped battery stats plenty of times now and seem to get no noticeable change. Also I've noticed that my battery will charge fully in 2 hours.

The best two firmwares for me so far have been Bionix Final (JI6 based w/JI2 modem) and Obsidian v2. Following my usual daily routine I'm getting about 14-16 hours from Obsidian v2, which includes a smattering of phone calls and texting, about a half hour of solid app usage (ye olde lunch break at work) and frequent checking of the display for time (I'm a manager with a fairly large staff so staying on top of what time it is, is a critical thing for me). At work I live in a very marginal data connection zone, with the phone frequently switching back and forth from 3G to Edge as well, and this hasn't had quite the negative impact on battery life that JI6's baseband usually implied.
I did get slightly better battery life with Bionix Final, but not enough better to justify going back. It seems my experience are quite the opposite of yours, or at least very different. With this being the case, I'd just suggest you use an app with more granular monitoring capabilities (like for instance Spare Parts) to try to find out why your battery life is so poor. I would wager it's probably app related and not OS related. Best of luck regardless.
If i used the phone like a computer i would get like 4-6 hours of usage (that's non stop usage) but if i used it lightly i can get like 15-17 hours. I guess it's not possible for me to use the phone with heavy usage for more than 6 or 7 hours.

This is the state of things. It's no different than your average laptop in that regard.
My wife is fully stock and I'm on the Ultimate KangBang Rom. Both have the ED01 Radio's and no 3G issues that we are aware of.
Since the update, we are both getting far worse battery life.
I have not touched the voltage controls in the rom.
Anyone have any ideas?
Could this be related to a 3G issue we simply are not seeing?
Should I (as she is not rooted) try to reset the battery stats after next full charge?
Should I call 228 to make sure everything is kosher on that end?
***************
Update:
I unplugged this morning at 7:30ish. 100% battery.
I started this thread at 10:30ish. 75% battery.
~3hrs, light use, lost 25%.
I hit both options in *228 at 10:30ish.
Its now 1:30ish. 71% battery.
~3hrs, light use, lost 4%.
I think the update, in general, just screws up your 3G/roaming etc. This was already known with other issues Verizon had over the last week or so. This seems, to me, as the most likely cause of battery drain.
I'll will come back later to say if anything changes. Also, need to see if wife ran the *228 options on her phone and will report back if findings are similar.
Hey superchunk,
I have a somewhat related post in the general section, and am finding low cell signal together with Google location services are giving me 4-8% batt loss per hr. See below. Also make sure to toggle airplane mode once per boot to workaround the 50% TWOS bug.

Check what apps you have installed. After I did the full update to ED01, and then replaced the kernel with Imnuts' -100 undervolted kernel, I was getting great battery life until I installed the full Skype client. Even logging out so the program would quit, the battery started draining upwards of 10% per hour, even when the phone wasn't being used.
It seems Android in general, and 2.2 specifically, is pretty vulnerable to errant battery drains. Worst part is that it didn't stop after I uninstalled Skype, so I had to go through the whole process again - back to DL09 and then update.
We've always had google services on (before and after upgrade), so I don't think that has anything to do with it.
Neither of use have Skype and no other apps have been installed anything new (don't use skype), but that doesn't mean something old has a new undesirable effect.
So far, I've ran the *228 options and will see if that helps. I'm thinking we simply haven't noticed 3G dropping and really needed the updates to programming and roaming.
Having a phone constantly searching for its best band will cause quicker than normal dead batteries. This is one of the reasons the Thunderbolt is getting so many negative marks for battery life, LTE just isn't there yet.

Have you charged to full and wiped bstats?
I hate to start a new battery thread but I've searched, read all the ones out there, and nothing seems to have helped. I just got this phone late last week and I first upgraded it to the latest OTA, then odin cww and finally installed com rom 1.3. Let me just say I've never seen a battery drop this quick. I haven't even activated the phone on my account because I'm so scared of how quickly I see it dropping without touching a thing on the phone. I also noticed the following:
baseband version
S:i500.04 V.ED03
Kernel Version
2.6.32.9
Build Number SCH-I500.ED01
The baseband and build ED0? don't seem to match up. Would this cause the problem? How do I fix that?
Just so that you get an idea, I've had the phone disconnected for 5hr 30min and I'm down to 55% battery with a fresh clean install of com rom 1.3. I did the battery calibration and that's about the only thing I've even installed on the phone. When I hit batt use here's what I get.
Display: 52%
WiFi 26%
cell standby 15%
Phone Idle 7%
I've had android for about a year and have an incredible that I love so I know that something just isn't right with this fascinate. Any help is greatly appreciated.
Thanks,
Mike
my understanding is that the build and baseband don;t have to be equal, baseband is modem/radio and build is just the rom i believe.
From what I hear, the only thing you have to keep track of is using an eclair modem with a froyo rom as there will be issues...
You can try going to the ED01 modem (works better for me vs ed03)
I also had battery "problems".. barely get through 12 hours without needed charge with little use.
I just installed Green power app from market.. it seems to work similarly to juice defender, just is easier to configure for the noob like me, and is MUCH more limited. works on the basis of only turning on transmission intermittently.
Now I can go 18+ hours and remain above 50%.. 80% if I don't touch my phone.
Turn off wifi when you're not connected, my phone lasts 36 hours using juice defender to turn off radios when screen is off

The radio firmware makes or breaks the battery life on this phone. I've tried every combo of roms and radio firmwares. Go back to the DL09 or EA28 (my preference) radio firmware and recalibrate your battery bro. The eclair-era radio firmwares have proven to be much better than the newer ones.

Com Rom is built off of ED01 so it will say that.
ED03 is the latest build basically the same as ED01 just 3 fixed some bug that had a few phones stuck on EA28 if I remember correctly.
I haven't noticed much battery difference between the different modem/radios, personally it seems like the kernels make a bigger difference to me.
Also if you just clear the battery stars to calibrate the battery the battery gauge will be messed up for a couple cycles, best if you run it all the way down too. One of tie batteries I was calibrating in my phone said 0% for almost an hour before it actually turned off.
These phones aren't great on battery life anyways. One of the good things about using a kernel like OTB included in com rom is it allows you to use aftermarket batteries and still charge then in the phone. I get the Samsung batteries (I think they are technically for the epic), out of China for $2 each. Have 5 of them right now the wife and I rotate through. We also have two external chargers, we both just carry a spare battery to use if our phones die during the day.
Thanks for the tips. I think I'm going to try the different radio files and see if that helps. I guess I was just wondering why my display shows as if it's using so much battery and if that was caused by some other conflict. I've had phones with bad battery life but this is just crazy. From the time I wrote the first post (a little less than 2 hrs ago) I've gone from 56% to 36% with nothing installed or running. That's just beyond bad battery life. Something is hosed. I'll try the radios and cross my fingers.
Have you tried under the task manager and choose the ram manager do the level 2 clear, should close everything that is running, that helps me quite a bit. Also auto rotate can be turned off when you aren't using it that will help battery life too.

As was stated earlier, turn off wifi when you are not using it, that will help a lot. Also under wifi settings, advanced, and change the wifi sleep policy to when screen is turned off. And when you look at those percentages under battery use are not a percentage of the total battery, just a percentage of whatever battery use there is. So if you are losing 8% of your battery per hour, that 52% next to display just means display is draining 52% of that 8% per hour drain. Display is almost always going to be the top drain because of the super amoled screen.
^^^ Yeah, display is most of it. Turn brightness down (as opposed to automatic or full brightness) and see how that helps. If that doesn't help, turn off mobile data until needed, if that doesn't help (should do this anyway) recalibrate your battery and cycle it like 2 times. Give it a couple days, it will go back to normal.
Radios are the biggest battery drain, not the screen, I've used airplane mode and watched movies with four hours of screen on time and used 20% battery, all you need to do is keep wifi off when not in use, it pings something like every 20s trying to find when you're in range of networks, 3g is your second biggest killer...also do not use auto task killers, for reasons I'm too lazy to get into...lowest screen brightness setting helps some but I've found it a pain going into bright sun and having to change it, the auto dimmer works rather well

Click on the items in battery stats and tell us how long your display has actually been on. The display on this phone can fairly easily burn through 1%/minute of being on (in fact, doing the math, my phone's display is at just under 1%/minute right now).
And, personally, I hate JuiceDefender and those apps. They're not fixing the source of the problem, just doing a half assed job of duct taping over what might be tangentally related (while doing horrible things to syncing). Try to find what is _actually_ trying to keep the network awake if that is actually what is going on (the Facebook widget is known to utterly destroy battery life). Make sure apps are using Push instead of Pull notifications where ever possible (Pull uses an astronomically large amount of battery life in comparison to Push).
I get around 15 hours on any other radio than dl09, on which I get around 24-36 hours depending on how much I'm using to phone. Also make sure you turn off wifi when you aren't using it.

Ok, thanks to everyone. I wanted to give you all a quick update in the hopes that this will help someone in the future. I replaced the radio file with EA28 and wow what a difference it made. I now don't see the percentages drop right before my eye and I have a shot of making it through the day. I'm also pretty surprised by the amount of battery the screen uses up. My AMOLED droid incredible usually shows the display as using the least percentage of battery. I guess the super really isn't that super.
One question I do have is if I go back down to DL09 to get the better battery life, what's the trade off?
I haven't noticed any differences between the DL09 radio and any Froyo radio.

I have a Thunderbolt running Das BAMF Remix 1.6.3 and Imo's 2.7.0 kernel (I have tried going between Batt Saver/Normal, and now I am on Extreme). I adjusted my brightness of my display to about 20% (instead of automatic), and when I am home I try to be on my Wi-Fi. For some reason, I am not getting a full day's charge out of my Thunderbolt (when I first got the extended battery, I was getting at least 32 hours). I read about people's batteries and I feel people with the stock battery are getting more/equal amount as I am with an extended battery. I tried running Normal setting on Imo's kernel at one point and I did not even last 12 hours, and I was on 3G doing only minimal texting. I tried Batt Saver, and the first day I used it, it was really good (about 10 hours and I was down to 75%, but until I got to 18% or so and then within 3 minutes it was dead, which was weird). But the following day it was not as good as it was, and it died again less than a day. I even tried the Das BAMF kernels and they have similar results. I am also trying to switch between InteractiveX/SmartAss/OndemandX, but I am not seeing too much of a difference (unless someone can give hints on which is supposed to lend to a longer lasting battery). Any advice would be appreciated! (And if you need more specs on my phone, let me know... I generally only text, I do not play games or do very intensive internet things).
I have found the best battery life on bamf stripped v1.1, I get better battery life on that than any other Rom I've tried including stripped v1.7 and all the other bamf versions. I'm running the 4.4.6 kernel, I haven't tried the batt saver kernel from Imoseyon yet. I get 2-3x's the battery life as stock and almost twice the battery life as any other bamf Rom
There are lots of things to consider about your battery life. If you look at your batter use on your phone does it show anything that might be suspiciously draining battery more than normal? If you're using Imo's kernel you can type "12" into the terminal when you are changing governors to see the stats of how long your phone is staying at different frequencies, does it show a high amount of time spent at the higher frequencies? How long does your phones display stay on for?
There are so many things that can drain the battery its ridiculous and randomly I will have severe drains at times that are only solved by a reboot.
eraursls1984, do you have an extended battery? How much battery life are you getting?
Beastclaw, battery use seems normal - nothing out of the ordinary or suspicious is really eating at my battery. As I said before, I am currently running InteractiveX and at Extreme mode, and these are my states at different frequencies:
245760: 2102206
368640: 409810
768000: 58113
1024000: 263351
1222400: 12737
1408000: 72575
1593600: 0
1766400: 0
1920000: 0
Seems that nothing is really running too much on high frequencies, mainly on the lower end. My phone display is supposed to stay on for, I believe, 2 minutes, but whenever I am doing using it, I always lock it.
I heard Autostarts was a good app that could help with battery life and performance (and I was warned to not change any system settings), but I am trying to see if maybe there is anything else I can do to figure out why my battery seems to not last as long as other batteries.
You can try using an app from the market called "CurrentWidget" It allows you to log how much power your phone is using at different intervals of time. My phone generally runs at 40-60mA when the screen is off and its not doing anything and between 400-600mA when the screen is on and I am running tasks. You can use the log to check to make sure your phone isnt drawing too much power in the down state. It even shows you the stats in a nifty little graph form

I have a stock battery and with normal use I get 12-14 hours compared to about 4 when I was completely stock. When I use my phone heavily, constant browsing, I get about 4 hours compared to less than 2 stock. I always have my brightness all the way up except for when I'm in bed because this screen is not bright at all compared to my old phones. Unless you just have to have sense (which to me makes no sense, lol) then I would recommend trying bamf stripped v1.1. I am also not overclocked, I noticed a little increase in performance but not enough to justify the loss of some battery life., however I was going to experiment with it again since I haven't tested the performance and battery life of stripped v1.1 overclocked.
I mean, I have BAMF Remix 1.6.3, which I guess has Sense elements since I do not have BAMF Stripped? I mean, I do not think I use any Sense features or anything like that, so I have no reason not to get BAMF Stripped if it helps increase performance/battery life. Yeah, on Remix 1.6.3 and Imo's kernel at Normal, I had 12 hours on my extended battery... Haha.
Bump - does anyone have Autostarts? Or any other program/app that will help with the battery life, or any other suggestions? I will test the CurrentWidget app tomorrow when I am actually up and using my phone and see if I get similar results or if I find another program is using up my memory... I also recently installed Advanced Task Killer today to help with this battery problem, but I heard mixed things about using it and how it can actually negatively impact the phone instead of helping.

Before 2.2 they were useful on some phones if used right, but its not needed nor does it work on the thunderbolt. If its set to autokill then it will drain the battery faster by running and killing apps, then the phone using juice to reopen the apps that were killed. If you root you can use autokiller (not a task killer) to set parameters for ram memory but I haven't found it to be necessary on the t-bolt, it was needed on my old droid X to keep it from lagging. I would suggest uninstalling the task killer.
Took your advice and uninstalled the task killer - thanks! Anyone else have any other suggestions or advice about my battery problem?
Autostarts is definitely worth $1. If you are familiar with Windows, it's kinda like msconfig for android. It prevents nonessential apps from starting in the background and wasting battery & network bandwidth. If you want to do everything you possibly can to minimize resource hogging, you should get Autostarts.
I downloaded Autostarts - I hate to be asking this sort of question but I am sort of cautious when changing these sorts of settings (because I heard a person who had to boot into recovery because he shut off system applications by accident), which programs should/shouldn't I turn off? I am a little confused how to use this program - did it automatically shut off some programs, because as I look through I see some programs are crossed off in a green line... Any help would be appreciated! Thanks!
Bump - can anyone help me with Autostarts? Any help would be appreciated! Thanks!

Sigh, Autostarts isn't a "task killer"
I stay away from any proccess that's needed to run in the background. Things in yellow, leave alone. IMO pandora has no business running in the background at start up. If there's no valid reason, I kill it.

I realize Autostarts isn't a task killer (it cannot kill a task if it never opens up, hehe). Thanks for your advice though! The more I was looking at it last night, the more I was understanding, but you just reassured what I was assuming. Hopefully this helps my battery a bit... Or I figure what else makes my extended battery drain faster than others.
Even with Autostarts, my battery life has not improved that much... I have been experimenting a bit with different governors and settings, but now I am back with the extreme Imo kernel and on InteractiveX. Does anyone have any other suggestions? Any help would be appreciated!
I was having trouble with my battery also. I've been lucky with Gingeritis but still the battery was killing me. This may not be an option but the extended battery is amazing. I got the case to go with it and I'm not disapointed. This OS with heavy use also and display at 50% and all animations enabled. Also running 4g all day!

The problem is, I DO have the extended battery and now seeing some of the battery life that others are getting (a lot say 30+ hours, I am barely pushing my phone and I am getting less than 20 at a time).
BAMF 3 RC2, imo 3.3.4, 245/1593, LTE Only mode, auto brightness, twitter sync every 15 minutes, facebook every hour, gmail push, weather every hour, 4 hours of music streaming, another couple of playing, a lot of twitter and facebook, and doing a bunch of other things with the phone, and I rebooted about 3 times. I think I could hit 50+ hours if i didn't OC or reboot.
Oh yeah, I have the extended battery

Hi all, I'm new to this part of the xda forums as I had a nexus before, just got the upgrade to the Atrix, rooting,unlocking of bootloader everything went well but I just flashed Aura's from with feux kernel and im getting really really bad battery life, like I'm talking 4-5 hours. There is one process thats really confusing me, its just called "x" and its sitting there taking about 35% battery, my screen is taking 55% battery.
It's getting really annoying as my nexus used to give me about 12 hours and the only reason I moved to the atrix was to get the better battery life that I saw with all my atrix touting friends (they all had 1-2 days battery life) I'm about to flash homebase and see if that fixes it but I don't know whats going on. I have a UK MB860 and I used http://forum.xda-developers.com/showthread.php?t=1196747&highlight=t-mobile+root to root. Pleaseee can someone help!
X is the webtop and there is a fix somewhere for that (doesn't completely work). Just flash CM7 beta. Its much better than any other ROM and has the best battery life. Everything except the finger print scanner and webtop work.
Also I had really good battery on the Ying Yang ROM.

I think I might give CM7 a go you know, I loved CM on the nexus, even after it killed the memory chips it was still good! Im going to try it, is it really stable?
EDIT:
since updating to CM7 and Wiping my battery stats I have some how gained 39% battery!

I find that all gingerbread roms have horrible battery life compared to froyo on the atrix. Cm7 battery is worse but the phone is smoother. Faux 1.3ghz kernel has even worse battery.

I was just about to post that lol. Also make sure every time you flash a new rom you are at 100% if not that is a sure fire way to cheat yourself out of battery life. I don't know if I'm just one of "the lucky ones" but I easily get over 16+ hours with moderate usage. I'm running CM7 beta with quite a few things frozen.
Ok so I followed the guide to perfection and it didn't improve the battery life one bit! I'm trying hard to find a t-mobile radio I can flash as I have read around it could be my radio that is the culprit and I am also getting rubbish HSDPA readings, I should be getting full bars but since switching to homebase Im only getting one bar.
Using watchdog I have noticed that the Xorg process is using over 50% cpu which does not seem right to be and I believe that because its a linux process Watchdog can't kill it. Is there anyway of fixing this?
1) Uninstall Tango, Facebook and Handcent SMS if any of the three are installed. They are huge battery drainers and you can find less battery hogging substitutes
2) Freeze any unnecessary apps, I believe there is a thread somewhere in the General section that has a pretty decent freeze list (if you flash CM7, you will have very little to freeze but that's good!)
3) Keep brightness down to a minimum when you can, I've noticed kicking the brightness up rather high can be pretty demanding on your battery
4) Set SetCPU Profiles to something like this...
Screen Off 216/216
Charging 1100/216
In Call 456/216
Battery <20% 456/216
Battery <10% 216/216
5) If you have the proper kernel set the CPU govner to power saver.
6) Undervolt, test yours and never apply set on boot unless you are positive it's stable, mine are something like this...
1100 MHz -50mV
1000 MHz -50mV
912 MHz -50mV
750 MHz -50mV
608 MHz -100mV
456 MHz -150mV
216 MHz -200mV
This way when you're phone is idling with the screen off, in a call or low on battery it is undervolting heavily to save maximum amounts of battery
With this setup I can get 30+ hours pretty regularly with moderate-to-heavy usage (weekdays/non-work days), 22-25 hours with more heavy usage (work days) and close to 48 hours with little usage (weekends).
It all depends on your usage and your phone but I have found this setup here to work fairly well.
I am currently on CM7 Beta, stock CM7 radio and stock CM7 kernel, running at 1100/216 when above profile conditions aren't met. 32% been running since 9 am this morning, it is now 3:15 am, today was a long workday.
I can almost guarantee (almost) that its your rom/kernel combination. Had same problem til I changed.

fastboot erase osh
That will nuke your webtop & fix your problem.
I'm now using faux kernel for CM7 and that hasn't improved anything, in fact I think it it has made it worse. It's getting really irretating because using the watch dog app it always says there is one linux process on every rom I use that is clocking at over 50% cpu usage and It won't let me kill it (probably because it's a linux process), its really annoying me because all I want is my phone to work properly but to enjoy the full rooting experience. I know countless amounts of people with atrix's and they get a full day and a bit out of their phone with heavy usage i can't even manage 10 hours!

Watchdog eats battery like a mthrfckr, get away from that. Install BetterBatterStats instead & look for wakelocks. Which linux process are you noticing with that high cpu usage?
How many hours of screen time do you get in those 10 hrs?
Have you tried with a fastboot wipe & internal storage format prior to installing a new rom? Are you using the latest recommended radio for your phone?

Turn background syncing off if you are using that, and get in the habit of doing manual updates.
Too many times (with ANY Android device) people leave background syncing on and it tries sending/receiving data in a weak signal spot when you don't realize it. That's like a hot knife through butter on a battery.
Leave syncing off permanently if possible! That's a huge improvement right there for anyone...

That's a bit radical, no?
I'd say use Green Power so the phone can update every half hour or hour. It's a smartphone at the end of the day..
