So sorry for adding to the battery life threads, but I'm pretty frustrated.
I've seen people posting screen shots with 18 hours uptime, 7 hours wake time and 50% battery on custom roms. I've seen people getting about 24 hours on a single charge.
I've had my evo 2 weeks now, and I've tried about 3 different ROMS and 4 or 5 different Kernels all of which promised LONG battery life. I'm currently running BakedSnack 1.7 with Kernel #5. My phone has been on 10 hours, 2 hours of wake time and it has only 35% left. Couple of short phone calls, 10 mins Pandora and a bit of browsing and texting here and there. I was expecting more after rooting, yet it seems almost the same as it was before I rooted.
Am I expecting too much ?
I've gone through the full discharge/recharge cycle about 4 times so far. Bad battery perhaps ?
will the phone charge get you through a day say 10 hour work day ( includes travel time )
imho your expecting to much with 10 hours in to your charge and still have 35% left is pretty damn good imho
Baked Snacks is a great rom ! its no the battery check your TWS
Depends what you are doing, some things (3d games, flash) will drain the battery faster than others.
If you are at 10 hours and 2 hours awake with 35% left, thats not too bad. You should end up around 16-17 hours with 4 hours of awake time.
If you are talking on the phone, that will drain your battery the fastest.
Make sure you completely condition your battery as well (as many posts show)

It will make it through but usually by 5pm its around 30%. I almost have to make an effort to use it sparingly though. I really like the Baked Snack Rom, its very slick probably the best I've had so far. TWS was 3% today.

I haven't even gotten into playing games or watching video on it yet to be honest and my phone calls are usually short.
30% by 5 stop please be happy with that lol

Have you tried SetCPU? I have stock rooted with SetCPU (Perflock Disabler ftw) and without a signal 13-25% of the time (meaning the phone is searching for a signal), I end a 10-12 hour work day with about 45-50% left. Underclocking to 250 while the screen off has helped a lot.
This seems to be a common concern. first please remember to take everything with a grain of salt when it comes to people reporting there battery times. There are just to many factors to say ok if you use this rom and this kernel you will get 20 hours of battery life. Also many of the people reporting battery life exaggerate. sure they may ahve gotten 50 hours between charges on stock battery... but they surely didn't have moderate use ... or any real use during that no matter what they claim.
from another post it seems the majority of people in that post (with everything tweaked calibrated and set up) were getting roughly 13-18 hours of battery life out of there phone with normal use. normal being defined by actually using your phone as a phone as well as using its other capabilities. So my feeling if you are a moderate user you should expect to fall into this area as a goal. Things to help would include setCPU, making sure you turn off data when you shut off screen (or getting a program to do so for you - juicedefender) and making sure you calibrate your battery and battery stats of your phone.
it seems like you are getting close to this range however you are having to watch your use to do so. as others have said the first thing i would do is get setCPU and set up a battery saving profile. read through some of the battery threads if you havent and look for setting changes that wont impact you tremendously but will help save battery (for example if you dont use landscape mode a lot you can turn off autorotation and save some battery). If you are using froyo and are running a task killer uninstall it since it doesnt work any way. While most settings will make a small impact together they should help get you to where you can use your phone moderately through out the day with out worries.

Don't get me wrong here, the thread wasn't about me complaining, more about setting my expectations.
2 Years ago I had the first Touch Pro which would be dead by 3pm regardless of usage. At one point I had 4 batteries. I got the Touch Pro 2 a year later and it could go 2-3 days on single charge with normal usage. It was like night and day.
Granted this is a much more powerful device than either of those, but I feel like I've taken a step backwards with the battery situation.

I tried out SetCPU but the phone was slugglish for me at times and once or twice I had to reboot.
I'm probably just gonna grab an extra battery and a desktop charger so I can charge one battery while the other is in use.

Thanks alot for those tips, I'll give SetCPU another go.
I haven't tried out Juice Defender but I'll look into that as well. Turning off Data when the screen is off might be just the thing I need!
So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,
Rocky
Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.
I have had the ultimate in crappy battery life since day one with my Vibrant. I have tried reconditioning, task killers, freezing apps, etc., etc. Very minimal gains and, in some cases, worse battery life. These things were draining just sitting on our pockets.
Here's where it gets weird. My wife also has a Samsung Vibrant and was getting the same horrible battery life. We were both charging dead Vibrants half way through the day. Granted, we are both moderate to heavy users but I expected more. A week ago, my wife was still sitting at 80% by lunch time while I was looking at 27%. Huh? I asked her what she did and she had no idea except that she had downloaded a battery monitoring app the day before. I thought it made no sense that this could have anything to do with it so I brushed it off. Over the next few days she was still getting killer battery life throughout the day.
So....I decided to give it a shot just to be sure it wasn't that app. Well, just before bedtime, my battery was it 7%. I downloaded the battery app, plugged in my Vibrant and hit the hay. By noon the next day I was still over 80% I have no idea why but I know it's working for both of us and it has to have something to do with this app.
I'm no programmer and I certainly have no vested interested in any android apps. We just stumbled on this and it works. Would anyone out there have a clue why?
I'm not sure if posting the name of the app breaks any xda rules so I'll wait.
Ever since i've been on JK2 Froyo my battery life has been excellent. But i'm interested in hearing which app you're talking about

I agree. I just didn't want to be seen as peddling a product here.
It's called BatteryTime. It's free although, I believe there is a pay version. I didn't adjust any settings. Just installed it, charged over night and I can't believe the difference nor understand why it made such a huge difference. I unplugged 4 hours ago and have 98%. Still a mystery to me but I'm not complaining.
There's like 4 of the same app on the market x)
What is the full name?
OH and thanks, I installed it, I'll report back with results.

Just Looked again and you're right. There are 4 versions there. I'm currently using the "BatteryTime Lite" version.
The only thing that I can think of to rationalize this huge difference is that the battery percentage was being reported incorrectly before. I may have had a charge that would last all day or longer but it was displaying an accelerated discharge rate which would kill my Vibrant prematurely. For one reason or another, this app appears to have corrected that and the indicator is (I hope) reporting the correct battery life now.
Does that make any sense?

Thanks for sharing. I will give it a try.
Update:
I found this somewhat disappointing. I rebooted my phone for the first time in about a week and on boot up the indicator is displaying significant drain again. I was at 96% before boot and 56% after? I'm going to recharge to full again and see if I still enjoy the same battery life.
Now I'm really confused. Sent an email to developer.
judging by the app description and most of the comments - the app doesn't actually *do* anything. It merely reports the battery differently.
No amount of software will change how much charge a battery can hold. The only thing that's different is how it's being reported.

Indeed, and that was my point to begin with. Originally, the battery indicator reported as critically low in no more than 6 hours. Soon after, the phone would shutdown until put on the charger. With this app I am able to get through the day reporting roughly 30% at bedtime around 10pm. Of course, that is subject to change on a reboot....until fully charged again. This is the mystery.
Yeah, there is funky stuff going on with battery meters. One that is included with the Obsidian Roms is Battery Left, currently, this is showing a 50% charge and 10:19 left. Next to it is Juice Plotter which is showing 21h 11m left. According to the system, i am at 71% Power and it has been unplugged for 6 hours. From experience, I know that the 21h remaining is actually accurate and Battery Left is completely dorked.
The point being, you can't always trust the battery meter.
So I installed a monitor also to try and figure out what was killing my battery 30+% over night and I had the same reaction....I woke up to a 10% loss. I realized what is probably happening is since this app is monitoring the phone all night...whatever app is draining the battery is probably a daemon that only runs when the CPU goes really idle for a certain period of time. More than likely that app inadvertently gave you better battery life because it runs in the foreground and marks your phone as being active so whatever app was killing battery never ran.

I think you've hit the nail on the head. Since day one, I have had buggy battery reporting. For instance, if I reboot the phone while it is plugged in, the reported battery level changes dramatically.
Edit: your later post supports this idea even further.
I installed this on my phone. This program does not attempt to save battery life or control anything on your phone. It does offers "Tips" to save battery life. Its main purpose is to indicate, based on your current level of charge, how long your battery should last given different circumstances - ex. idle, talk time, video time, audio time, etc... Thus the name BatteryTime.
That's all that it does. Any perception of a longer lasting battery may have been an anomaly as does happen sometimes with our phones. One day you'll seem to be getting awesome battery life (and there is likely an underlying reason which we'll never figure out, but which jives with the battery) and the next day it is back to draining quickly as normal.
There are three certainties in life: death, taxes, and posts about battery life in smart phone forums.
Anyone have the issue where they charge the phone overnight, the phone reads 100% in the morning, you unplug it and you are immediately down to 7% battery? It seems to happen to me at least twice per week. It is a terrible bug.
i dont get it you said that before the battery wasnt being read correctly so it shut off fast but now with the app it reads correctly and last you the whole day with 30% left to spare?? wouldnt that technically mean it increased battery because you got it to last all day plus some? just by making the phone read the battery correctly.
I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.
Sent from my SPH-D700 using XDA App
I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??
Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.
I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!
I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.
ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.
Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.
DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.
I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.
I have been letting a couple of days go by to see how the battery is and I have got to say that I am highly not impressed. I love the phone and even like Blur but the battery is really a let down. I know that the first day or so that I use the phone heavily because of course.. ITS NEW. But today I have been real busy at work and have maybe text a few people, made 2 calls, and looked up a number using google maps and my battery is now down to 60%. In battery manager, it says 5h 2m 25s since unplugged which would be me taking the phone off the charger this morning and heading to work. Other stats are:
Display 35% 29m 52s
Phone Idle 26% 4h 32m 47s
Voice Calls 24% 6m 45s
Cell Standby 11% 5h 4m 5s
Wi-Fi 6% 1h 51m 56s
From looking at these battery stats and usage, does it even seem correct to be at 60% battery? This is at the least very minimal usage for a phone.
Yet another battery thread... One thing before people start complaining: don't estimate battery life based on battery gauge! Complain once the battery is dead and you HAVE to charge. That's the real mileage you'll get from your battery (and give it a few days to calibrate). The gauge is not a good indicator.
I am a new Atrix user too and so far the battery life is 12hrs or less. Maybe that is not impressive. Coming from the N1, its alright in my book.
I do want to say to everyone complaining about the battery life:
It can take a week or more for the battery to settle into the routine and perform to its maximum ability. Lets start the conversation again later next week on where our battery is at.
Yesterday I got 13 hrs between unplugging the phone, and getting the 15% warning. Not all that bad. Not great, but definitely could be worse.
mine has yet to drop below 30% and im pretty much browsing the web and texting all day. I dont care what kind of phone you have but making voice calls and playing games/watching videos kills battery with a quickness no matter how big a battery you have. . The atrix in my personal usage is just as good as my ip4 was.
the atrix was very good on battery life compare to other android phones i've had
Have the Atrix and Epic 4G and the Atrix lasts easily twice as long as the Epic.
I have to keep he Epic pluged in for my hour comute with pandora, just to make sure I have enough battery to make it for the trip home. Normal usage during the day with brightness all the way down, wifi off, BT off, sync On.
Had the Atrix today (day one after full night charge, unpluged at 6:30a), kept BT On, WiFi On, Brightness 100%, Sync On, Exchange Sync On, Auto off/standby set to 15 minutes, Pandora on via BT for my hour trip (unpluged), forest Live Background, Weather Widget etc.,downloaded everyting I could think of/find, constant e-mail, and constant "whatsApp" till noon (lunch), wache YouTube Videos for my whole hour lunch (still full bright mind you). Created 10 minute Install Video with 720p for work, then uploaded via WiFi, not USB. More Texing, Calls and Downloads. .... FINALLY haed to plug it in at 2:30p, with 5% battery left, I think I could have made it till 3 for sure.
That's a full 8 hours of NonStop Use of everything. I expect to get Morning-Night life from normal usage.
Final word. Test it first. I did and it's Great, not just good. The receiving end of all my texts and e-mail blasting and video look ups has an iPhone. He had to charge his at 2:30 too, but has his iPhone set to max battery save (brightness 15%, wifi off, sync off, etc.) But was using as intensly as I was
... okay I'm done ...

Well I must have a bad battery or something then because I am not doing nearly half the stuff that you are doing and am now at 30%. Is there any special charging methods or anything that I should try to squeeze out a few more hours on this puppy?

may be you have several internet connected background service running behind the scene?
My attitude towards the battery is a mixed bag.
1) PRO: It blows away the battery for the Eris (which I'm coming from)
2) CON: As these phones come to be computers with phone capability, it's really time for manufacturers to try their hardest for better batteries. I'd eagerly accept a phone twice as thick as this one if it meant double the battery life.
I find mine is only good for 10 hours (much less with heavy usage, but low calling time). I expected more.

I really call bull on this.
Coming from the world of Airsoft, I'm no stranger to battery performance.
Most of these performance myths are hold overs from the Ni-Cad days and don't apply to modern batteries.
Call Bull all you want. But it was true to the N1 and so far its been true to my battery. It does not last the first few days and gets better after a few charge cycles.
Frankly, everyone believes whatever they want on batteries. I for one take it as a user by user experience. I watch my battery life a lot, but I also like to have Google Reader and Google Listen syncing.
I'm at 30% right now and 12 hours unplugged. What I wouldcall moderate use. Its not as good as my captivate on custom rom / kernel but its far from bad enough.for me to complain about

Andriod sucks the battery, bigger battery on Atrix didn't help much. Google need to optimize the OS for better battery management. I am disappointed coming from Samsung Focus & iPhone 4, both have superior battery life. BTW, I am on Day#4, conditioning the battery didn't help any so far..
Within Range
Looking at all the comments - I would say the Atrix is within range -- I knew when I saw the 1950 mAh (or whatever the exact spec) that the tegra processor must really be a power hog -- the new processor, along with the huge screen is going to draw a lot of power. Comparing to other phones with single core processors and screens even 20% smaller is not reasonable.
Definitely a good point... going to be interesting to see how well other dual core are going to hold up. That will be a better comparison.
Is that battery really a 1930mAH? The size looks like any 1500mAH battery isn't it?
I managed to get close to 16 hours of 'normal' use, meaning I wasn't trying to drain it, nor was I trying to conserve battery. I took the phone off the charger at 3pm and made it all the way to 2pm the following day with about 20% left. That's 23 hours, but I subtracted out the time the phone was on while I was asleep, 8 hours (nighttime mode).
Hmm hearing all these replies i believe i have a defective battery. I unplugged mine today at 5:15AM and now it's 2:18PM and it's just gave me the 15% beep. I've sent about 25 texts and played some words with friends. I've got watchdog installed and no apps seem to be out of control. I'm wondering if a factory reset would fix the issue or if i should return it.

try going to your dialer and entering *#*#INFO#*#*
Look under the battery usage and check the different items. Is anything using a significant amount? it could be a rogue app.
I will say MotoBlur has a lot running in the background. About twice as much as vanilla android.
I have turned most of this off and I do know that is helping my battery life.
