Battery Sanity - EVO 4G General

Okay, got my EVO 4G and found that I had the same battery woes that everyone else does. I searched the web and found all of the phone tweaks and settings to improve battery life as I am sure everyone else did. That gave me varying degrees of success. Shortly I discovered rooting and that open a whole new world to me and my phone. Finding out that I could flash roms all by myself was exhilerating and fun. This also helped with my battery life and I now have what I think is a respectable battery life for a phone that will do all the things that an EVO4G will do. The last mod I did to my phone has taken the percentile increments out of the battery icon on the toolbar. Trust me folks this is a good thing and will make life simpler and allow you to move on to more important things. I am no longer a slave to the toolbar to see how much battery life I have left. If you must be able to access the exact percent at anytime, just download an app and go to that. If you feel the urge to check it more than once an hour, simple rub your earlobes and repeat "woosa" over and over again. It will be okay. Let's all do this now, before there is a need for a battery twelve step program. Woosa, woosa.

This is a funny post. I too have found that no percentage in the taskbar = less anxiety.

I enjoy my phone so much more now that have learned how to turn on my EVO Zen mode.

And today I find myself back sliding and tweaking my battery again.

I'd just get another battery, an extended battery for my EVO like the one here.

I may need to do this. I have an extended battery and my battery life has improved considerably but I find myself checking it all the time thinking something is eating my battery and I need to hunt it down and force close it. LOL
I updated to the newest CM7 a few days ago but it was doing all kinds of hinky stuff and my battery life went down to about 7 hours and it was using battery heavily even in airplane mode. I do back ups religiously so I just nanded back to the original CM7 stable and all is well again.

JI6 update: a *serious* let-down, in my opinion

So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip
For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !
Better than Windows NT = 1.6
Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.
Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.
You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.
Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.
You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

I'm having terrible battery life as well.
i'm 24 hours unplugged, sitting at 27%

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...
Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.
You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.

Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?
turn off gps when not need
data when not needed
Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps
also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running
@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks
Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.
I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.
just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery
My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.
i owe setcpu and screen off seting for my battery life
I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.
I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

For those who have bad battery life...!

Some hints:
1) Flash Bi-Winning V2. Not V3 as I found the V2 has better battery, and V3 doesn't have too many advantages.
2) Keep brightness at low or medium-low. I doubt you need to ever put it on high. If you really want to be smart, use a brightness widget. (the one from curvefish works well
3) Try to have little to no widgets on homescreen. If you must have widgets, use trusted/well-reviewed ones. I installed a clock widget and it drained my battery in 9 hours.
If the above still does not work, then continue. If you are feeling you are getting great battery life, then continue. NOTICE: One major reason why people are getting poor battery life is too much tinkering. After seeing other people are getting better battery life, they try to flash new kernels/modems/roms/etc... and it turns out the new is worse than the old. Then they go and complain. SUMMARY: If you are feeling you have good battery life, then leave it. You should only worry if you do not get at least 12 hours on VERY LIGHT usage. (5 phone calls lasting 10 minutes, Checking emain every 30 minutes. Having fetch for 10 minutes, not push. No widgets, no music, no games etc...​
4) If you still do not have good battery with biwinning v2 flash the BALI UV kernel.
5) If you still do not have good battery, try other kernels. Kernel is the one that mainly controls battery.
6) Do you live in an area with poor reception? Try a modem that has good signal-getting abilities. Searching/switching drains battery.
7) If you still do not have good battery, try other roms.
8) If you still do not have good battery, then there is something seriously wrong. Either you are using the phone too heavily (gps etc...) or your battery is worn down. Get a stock replacement.
9) If you are here then just get a extended battery. There must be something wrong with your phone, so either exchange phone or get extended battery. If you do not want buldge get a 1600 or 1650 mah battery.
10) If you are here then throw your phone of a cliff and get this:

11) If you still do not get good battery live under a rock.
NOTE: EVERYONE'S battery life will vary based on usage and other factors.
That said, I am getting 30 hours usage with 50% left. 20 minutes of gaming, 8 phone calls, checking email.
YOUR tips aren't going to work for EVERYONE else.
Everyone's phone is unique, they use it differently, at different times, it depends on what YOU do.
If your gonna use your phone for HD Graphic games 24/7 its not gonna last 10 hours its common sense.
If your so worried about your battery then you know you should turn off GPS/Blue Tooth/ Turn down Brightness.
It's all common sense.
What i don't like you did was firstly, single out ONE ROM for having the best battery, depending on your usage.
Truthfully, i get 2 days of battery on CM7. I don't use my phone to play games and **** not all the time at least, text, phone, music, news , and browsing is what i use it for.
I forgot who it was i think it was Eugene who said
If you want your battery to last, treat it like your mother, not a piss poor whore.
Could also be because bi-winning v3 is still in beta while v2 is not.

Seriously, battery life has to be the #1 topic or complaint on every Android forum about every ROM, Kernel,or Modem. Thx for the tips krackers and everyone else who tried to find a way to conserve battery on these life sucking smartphones we have now days. Also, you're right xriderx66 "EVERY VIBRANT IS DIFFERENT" no matter how you look at it. What works for one person won't work for the other. By now we all should know the basics of batt. conservation, like what to turn off / remove and to o/c or not to o/c and of course the biggest battery drainer which is how long the screen is on or how bright u have it.
My point that I'm trying to make and that I had made on other forums (which alot of people didn't care about) its that we have these phones that could do so much but we constantly trying to conserve battery so we take the goodness out of the damm phones. I wanna have all the widgets I want running, I wanna have my brightness to 100% so I could see it well in the sun, I wanna have my bluetooth on all the time so I dont need to pull my phone out and dirty it at work. I wanna have either my wifi or data on all day cuz ant any given moment I wanna listen to Pandora, go on you-tube, or browse the web without having to switch this **** on or off, I wanna have my phone running like 95% of other Android user who don't even know what the hell a ROM or Kernel is but don't worry about tweaking this or that like we do so they enjoy their phones even though it kills their batteries.
So how do I do it??? Simple.... I went on eBay. I got three t959 batteries for $12 total (with s&h).I got a t959 battery charger for $3.50 total. I got a wall and car charger set for my phone for $5 total. Now I got a phone charger at home,work, and car. I got a battery charger for all my batteries. I got three fully charged x-tra batteries ready to swap whenever I need to (and not the 3500mah cuz I dont like my phone fat). All that for $20.50. That is how much it cost me to stop being obsessed with my battery life and to fully enjoy my phone. I think alot of you out there should think about doing the same so you're not obsessed with battery life. ENJOY YOUR PHONE PEOPLE

consistently mediocre battery life even after calibration and undervolt

I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)
I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!
Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.

a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol
1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

Well, if you keep data or wifi turned on at all times, then there's no way you can have something more than mediocre battery life, sorry.
It's not the Atrix'es fault, its the brutal truth with all modern smartphones.
1 personally run ninja speed freak, i get amazing battery life. simply amazing, days on worth of battery!
it is not a kernel issue, i simply dont know exactcly what hack in particular gives ninja the amazing battery life. but im working hard to determing this so i can share it.

Perhaps, bypassing MotoBlur sign in
I'm not signed into motorblur either.
I do turn off wifi when out, but bluetooth is normally on.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.
I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.
Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .
The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).
These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)
P.S.- Please don't post "My battery lasts for over 9000 hours." and think that's enough info. Use your head.

Best tips to save some battery juice [easy]

I'm going to make things a little different now. I see a lot of threads here, and the only solution are: don't use X, low down performance, blah blah blah.
I'm going to make a change at your psychological side, or at least try. That's your worse enemy, which will make your battery last shorter.
**First part: testing ROM+Kernel combo
1. Install your ROM, delete the apks you don't need, and make some tweaks you want. Done?
2. Install another kernel.
3. Configure your device by installing your apps and stuff
4. Reboot
5. Test your combo for 1 day!! Only 1-one day.
6. Read second part to see if your battery life is good
**Second part: what should you consider while testing your combo
1. After the one day test [morning to evening], is your battery still working? If yes, you HAVE A GOOD BATTERY LIFE. You shouldn't care about how % the battery is, as long it lasts for the day.
2. If your battery is really going down fast, and it doesn't last till evening
a) Change kernel and try for another day.
b) Use BetterBatteryStats to see if there's something pissing off your battery
c) If you really need this extra juice to make it last till evening, low down ONLY A LITTLE BIT THE PERFORMANCE
3. Is performance good? If yes and your battery lasts or the day, you may now be happy.
4. Is performance bad? If yes, I'm going to say something to you. WHY THE HELL SHOULD ANYONE BUY A FREAKING 1,4GHZ QUAD-CORE **** TO HAVE BAD PERFORMANCE? Increase your performance, and if it's enough to get it alive after you go home, it's enough.
**Third part: things you shouldn't do
1. Don't put the % at status bar. It only makes you paranoic about looking at the battery %
2. NEVER check for available RAM, or battery %, but if the battery icon is going down quickly, make the basic stuff to save juice. Checking RAM and stuff will only make you complain at your ROM/kernel forum, even if it's normal. And don't use task killers, Samsung's task manager, etc. Cleaning memoy will only piss off your battery and cpu.
3. ALWAYS put your phone in the charger before you go sleep. Why would anyone want to make the battery last for 1d or 2d? Bull****, just charge every night, I see no problem by doing that.
4. USE, ABUSE, RAPE THE CRAP OF YOUR PHONE. Your phone is there, and have you think about how you use it? To check for battery % or actually use the phone?
**Observations
1. There's no such thing as miracles for that. Anything can count to change the battery drain: temperature, external temperature, pressure, apps, how you use it, etc...
2. Choose a stable kernel and DON'T undervolt it. Yeah, undervolt can be useful, but makes stability looking like crap.
3. This may be completed later.
Hope I could help some battery freaks here

One day is not even long enough to calibrate the battery on a new rom .

Why are so many users posting stupid untrue stuff just to lead noobs up the garden path .

I know a couple things to help with the battery drainage, from personal experience.
1. GPS, turn it the hell off unless you truly absolutely need it.
2. The Facebook app. One of the biggest battery hogs I know of besides heavy 3D-games.
3. Sync. Why choose to auto-sync? Turn it off and sync only when you feel you have to. Check Gmail manually, manually sync contacts and stuff when you feel it is needed
4. Location services. Might prove useful to some, while to others it drains the battery quicker.
These are the four battery hogs by my experience. You may not think the same.

GPS is really only on if an app is using it, if you have it on but an app is not using it it will not drain the battery. It's shown under settings battery and it shows GPS using no battery unless an app is using it.

Just a Snapple fact. Longest commercial flight possible is 18 hours and that will take you more then halfway around the world. And at the 16 hour point the co pilot is looking at the fuel gage, sweating profusely, and mentally going over his Will.
That does not include layovers. But at that point you have access to outlets.
Now with that out of the way. Lock this shiz.
OP, while others might have not been receptive to your thread you were the first to really start the flaming by name calling. I didn't see anyone calling you a "*****"
I saw people not agreeing with you and voicing that, but you were the one that actually crossed the line with the name calling and such.
Thread closed (and will be cleaned)
