For those who have bad battery life...! - Vibrant General

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.

Not starting a flame war but..
Counter-Point 1) I originally stated that results will vary.
C-P 2) Some people have bad battery even with those things turned off
That's all... Goodnight!

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

MESSAGE to HTC, Tmobile, Android and Google

There is a problem with our battery life and we all know its true... I have even been given a new battery and HTC mains charger
I turn off any service im not using at the time (ie: wifi, BT, GPS, NETGPS,etc) not that I should have to do this, but lets story on track...
My battery will make about 1 day as I am A "power user" but if its not plugged in I wont have the juice for my alarm to wake me up, my wifes Sony Ericsson lasts 4-5 days per charge, but lets not compare apples and oranges, the whi-phone 3g my sister has sahe bought it about the same times as my g1, she hadn't ever heard of "deep cycling" 2-5 times when you get a new phone, she never lets it discharge fully and just tops off all the time, AFAIK she is treating a NIMH cell exactly the wrong way, BUT SHE GETS 1-3 DAYS depending on the type of use, and never turns off ANY of the 3g, gps, net gps, wifi, BT nada and Id say she uses hers alot because its her primary camera, GPS & A/V player
my question is WHY?
Im sure there must be somebody involved with the development of this phone/OS that reads thru here, since there is more exciting stuff coming from XDA than there is the market...
Im gonna add a poll that pertains to battery use...
I wanted to add one very negative one but hit submit not preview, maybe just post and dont vote if none apply..
they better come off a new battery almost all other new phones will get 1-2 day + average use, Ive had phones that could go 3-4. but the state of the art G1 mindblowing innovative phone wont even work a whole day, so what if its bigger than the whi-phone, it has no keyboard.
I for one would like to hear some solid info on a replacement battery and back, for new and existing G1 users, early adopters got the fuzzy end of the lollipop on the HTC->headphone jack adapter I got the headphones with the htc angled adapter from fleabay, so many manufactures stick it to the early adopter, when we are the ones that get the word of mouth going, as people go "WOW that thing is cool!,what is it?! they know when we bought out phones and should be able to figure out when the head phone rev change was made, so send them to the first of the buyers....
IF the battery issue isnt fixed, alot of people will be very angry and the g1 will flop.
I think the bad press is starting to out weigh the good press the G1 and possibly android as a whole is at a crossroad. If the g1 tanks Android will be stained forever...thankfully enuff I dont think XDA-DEV would give up on this badboy, I love this thing, and I love it for what it can be
BhanG
Well stated sir.
HTC/Google need to fix battery problems in G1. Maybe it's soft bug, but maybe it's a hardware bug - Nobody knows
I dunno. With normal use, I get about 12 hours or more from my stock battery. That's about the same as other HTC phones I've had.
there is a battery issue and we are al aware of it.
i have managed to have it last through out the day
just set the brightness to the lowest possible, sleep time to 15 secs
turn off data and wifi and anything else that you are not using
its not how the phone was intended to be used, but it's what i ave to do for now
I find it fine for everyday use. Of course I haven't done a full test but maybe tomorrow I will.
I would like to use my G1 like I use my WinMo but no way I can with the battery.

I think you're exaggerating here a little bit. The battery life, while it got press at first, has faded from the limelight of android news for the general population. The G1 is already far from a flop and I don’t think there’s going to be a sudden mass return of all the handsets sold.
Let’s face it living on the cutting edge means you will get cut sometimes. Your high expectations will not always be met and manufacturers will frequently not care. The battery life is less than what many people expected, but we’ve learned to deal with it. At least we have options (power management, backup batteries, and expanded capacity batteries), but I’d not hold my breath on HTC making any major moves. How long has the issue been going with the TYTN II drivers anyway?

I have no idea what kind of use gets 1-3 days, but it certainly isn't 3G web browsing. Most iPhone 3G battery life tests clock 3G data use at about 3-5 hours. Based on my own usage of a friend's iPhone 3G, that seems to be about right. Coincidentally my G1 gets about 3-5 hours of 3G data use as well.
Frankly, from an engineer's point of view I have not seen any power drain tests conducted with enough rigor and variable control to be worthy of being called a truly scientific analysis. Even the best "battery life tests" out there aren't declaring what type of testing environment (los and distance to closest 3G tower), what background apps are installed, ambient temperature (which affects the battery discharge profile), etc. Without considering and removing these variables from the test, deviation could be as high as... well there's no fixing the percentage really. It's all just junk data.
I do notice after I installed Task Manager, to close out programs I am not using my battery life went up. There are a lot of un needed start up apps.

Yep my friend has iphone and we did test last weekend, both went 3 hours and change then died. If i dont use internet and set timeout and brightness down plus use task manager mine will go as long as my dash. I personally dont care about the battery life, i have a computer, home charger and car charger and i drive for a living so if it gets low no biggie. In my opinion i dont see android going anywhere and i love the g1. Just like wm its gonna take time to get off the ground. To say its at a crossroads is ridiculous.
I am using ADP1.1 and yea if I am browsing the net with 3G for 3-5 hours straight I start seeing the battery go down. But from 100% to 0% takes me longer than 5 hours. I know because I like to lay in bed and don't care to come check my messages LOL
I bought a G1 last week and so far I have been really dissapointed. After having an elf and seeing other htc phones I was expecting big things from the G1.
I am now a week into ownership and after 5 full charge - discharge cycles I am managing to get 24 hours out of the phone with next to no use what so ever. If i check my emails and do 30 mins browsing the phone is dead in 6 or less.
The hardware is simply put 'very poor' my screen is wobbly and the back is loose, all this after just a week.
As for android, it is fantastic everything I expected (except hotmail support) and there is no way it is going to flop. Its just a shame that google and htc didn't wait until they had the right phone for the job.
Thats just my 10p worth!!

It all depends on what you have installed. for me the start up is. I beleve amazon does too, but I uninstalled that. But the first thing I do is go into task manager and kill everything. And only like two things auto start up. I really with HTC built in a x-button app for android. I loved the click x for close.

Under light usage I get about 36 hours from full charge to shutdown. That's GPS on, Bluetooth on, Autosync on, periodically doing e-mail and web browsing.
Under heavy usage (Which is basically I listened to MP3s for 2 hours) it goes at least 17 hours before I plug it back in. I haven't tested but I'd bet it could go 20 or more.
That's as good as (or better) than I was getting on the Wizard/MDA.
I dunno if anyone has stated it but the problem with the battery has to do with the phone recieving the cell signal. For some reason the phone runs in overload when searching for a cell signal...I noticed this one day when T-Mo suspended my service and my battery meter never moved all day, I think by night it was down to 85-90%...sure enough that night when I paid my bill and the phone started picking up signal again, the battery depleted at "normal" speed.

Why do i keep hearing that there is no hotmail support? Android (and G1) works with hotmail just fine! Just go to the Email program and set it up. WHY!! .. I am having connection errors sometimes though..
Battery is a big issue. Never had any luck with it.. EVER.. just unplugged it and after about 1+ hour it's down to 66%. Played a game (slide puzzle) watched 2 youtube vids of about 3 minutes each. And I had it fully drained and recharged a couple of times in the beginning. It didn't even took 10 minutes to drop from 100% to 89%.. But I was on wifi.. Maybe this is normal.
Software has a lot to do with this I think. Yesterday I had about 50-60% left. Did something, can't remember what, opening programs or music. And closed it. After 5 minutes I checked and battery was hot and had drained to orange level. I checked with task manager and only calendar/messaging/tunewiki/music was on. I closed all and restarted the phone, cuz it was still hot. Luckily it lasted a few hours till I got home, with very carefull use..

WTF is up with the EVO battery!

first off, i love this phone. no joke, but the battery is well...laughable to say the least. on my HD2 running android, i get double the battery life and they HD2's battery is a 1200 battery, the EVO'S is a 1500. and android boots off the SD CARD and has NO POWER MANAGEMENT on HD2'S. my evo dropped to 54 percent battery today in 3.5 hours. no wifi, no bluetooth, no GPS and no 4G...all im saying is... WHAT THE ****!
It gets better. Load up some custom kernals + setcpu and you'll get great life. I'm running CM6 + snap 8.2 and it lasts the whole day with moderate use.

There is plenty of info on battery issues with EVO.
First... I would recommend rooting.
Second, use the FRESH build based off the new OTA leak.
Finally, change Settings / Mobile Networks / [uncheck] Enable Always-on
Then... ALWAYS keep your WiFi radio on. Add your home network if you have one... and wherever you go, add whatever hotspots you are in proximity of.
And if you ever consider doing a new build, backup your WiFi access point data via Titanium Backup before you do.
That should just about cover it... You will get a full day of use PLUS some out of that battery.

When you rooted it, did you also flash the newest radios? Trust me on the fresh build.. it rocks... but also, most importantly, use WiFi whenever possible... and turn off "always update"... those are all the most important.

No when I got my evo I was clearly.told and shown a doc from sprint (the manager over mobile area is a buddy) to tell everyone to expect 6 hours of battery life with normal use. I was able to squeeze out 8 - 9 myself. I know people say conditioning the battery is a waste of time . IMHO do it I noticed a nice increase in battery life. I have to laugh at people who get pissy about battery life when they are holding a mini PC.
Myself i avg. 18-20 hours a charge with normal use. I have 2 backup batteries so I don't worry to much about juice
from the fade
I really dont feel the Evo is a bad phone h, hell I love the damn thing . I just feel HTC kinda screwed up things in the process . One telling customers to expect 6 hours of use is alittle of a joke . Who the hell only works six hours a day ? Or is that six hours also include you getting up getting ready for work then coming home before you go to bed ? Second , its pretty clear the Evo has a bug in its charging system . People have reported that using stand alone wall chargers to charge the batteries they are getting improved life out of the batteries (Sorry I have never removed a battery from any cellphone I have had in the past to charge it and not gonna start now) . Third yes the HTC Evo is litterally a pocket pc with capabilities most phones dream of having . Then why the hell did they give it a 1500mah battery ? Thats like strapping a 55 gallon drum of fuel to the space shuttle and saying "Yeah this outta make it" . Sorry for my rant had to get it out (plugs phone in to charge again) LOL
OP, I like you, you're funny
A couple things..
1) Why do you have your CPU governed below 700mHz while awake??? You won't save battery that way, your phone runs at a gHz, use it!!
2) Setting your min/max both at 245 on sleep will actually decrease your battery life and your phones wake up performance, maybe not much. Capping your phone at 245 when asleep makes it a harder transition to awake because it makes that sudden jump when you wake it up. Setting your max somewhere over 600 on asleep, and setting it to OnDemand will ease the transition from sleep to awake.
There is no shortage of battery life tips but here's one: The auto rotate function polls for g-sensor status like once every 15 milliseconds. I use a switch on my homescreen to turn it on when I want it and keep it locked in portrait when I don't need it. This will help conserve some juice
I'm only scratching the surface here, I'm sure you do realize what a wealth of info there is on the subject already. FWIW, I use the crap out of this phone and I consistently get 20+ hours out of a charge. Good battery performance is achievable!

20+ Damn, what rom and kernel are you using? Im kinda having the same problems too. Im limiting my phone tryin to get better batt, that ****ing sucks. I just want to use my damn phone, without much sacrifice. Thanks
Why the hell do you have 4 phones running the same OS?

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.

@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!

Want to update Wife's Inc, not make her mad

So my wife hates the battery life of her Inc. I even got her a bigger battery (the one that is bigger but still fits with the stock back) and its really gotten bad. She gets maybe a days use. And use for her is hardly any data mostly talking on the phone. Its maybe 30mins to an hour on average of talking, some texting, and that its about it. I would think the battery would last longer.
I am no stranger to rooting and loading Roms, did it on my Droid 1 and now on my Thunderbolt, but the wife's phone has been off limits. But now its getting to the point where I want to step in and improve it. So I don't want to be flashing roms all the time, just need a stable rom with some nice bells and whistles, a good kernel for battery life, and I can load it and not have to worry about it.
ruby rom 2.0.2 and incredikernel 4/19 and then underclock it in gem settings. the best battery life ive seen ever across any android device ive had. its an aosp rom meaning no sense widgets, but that can be fixed with a third party launcher like Launcher pro plus. Not even sure if thats a factor. You could also try the xda superpower app wgich gives you automation with certain battery drainers, ie. 3g. let me know if you need help, because I have been on the quest for long battery life for a while and this is it.
I think she likes the Sense stuff, don't want to make it look too different than what she has now.
skyraider 4.1 with stock kernel then.
When you say "stock kernel" do you mean the kernel that comes with skyraider or the actual stock kernel (or does skyraider come with the stock kernel?).
it comes with the stock kernel. also check what is syncing and how often in system settings.
yeah I have clean out her syncing stuff, Cell Standby is using the most power, so I am not sure what is going on.
something is syncing definitely too much. my standby time is around 3% all the time and I manually sync.
I'm running SR4.1 with chad's 12/23; I unplug at around 7:30, and by the end of the day (around 10pm or so) I'm usually sitting at around 50-75% battery; that's with wifi/data off (turned on when I need them) and moderate texting (phone on vibrate) all day.
If you're getting Cell Standby as the biggest battery drain, that means she's in areas with low signal and its trying to find a stronger signal.
^^^^ That too. Forgot that part, but for whatever reason ive noticed sense roms have higher usage. Coincidense, maybe.
Do you mean higher usage as in Cell Standby or just in general? Just in general I can see why, because it has to draw more graphics on the screen for the UI.

im talking cell standby. strange, I know.
Hmm, that's weird. Could be because of stuff like HTC Check-in services, since that stuff would be in Sense ROMs...but idk. Guess all I've really used were Sense ROMs, so I don't have much of a basis to judge from.
Cell Standby is when you have no service. That is when it's constantly looking for a signal and can't find it. That's why her battery life sucks. In low service areas, when the service goes out, it starts searching for a signal, which eats battery life. I have the same problem at my job, because there's like no service there. Can try putting it in airplane mode in those areas (which makes it use almost 0 battery), or get JuiceDefender (works great OOTB) and use that to only allow sync's every X minutes......

Not necessarily no service, but low service as well. I live in an area with low signal in places, and work in metal buildings that really cut my signal down as well.
Well we work is roughly the same area (maybe half a mile apart) and I never have that much usage on Cell Standby. Something is screwy and I am hoping a new Rom and kernel that does some unclocking might help. Maybe starting fresh I can configure it better.
She took it off the charger this morning at 100%. When she gets home I will post her battery level and usage info.
1/2 a mile can be a big deal. I don't know the kind of environment / area you're in, so I can only guess.
You could also try flashing a different radio if you want, too. Heard good luck about that sometimes.
Magnolia ROM. Rock steady; NO issues at all.
Tried and true
It doesn't seem to be getting any more updates but Incredibly Re-Engineered was my go to for speed, stability, and battery life.
re-engineered is a good choice as well.

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.
Sent from my MB860 using XDA App
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.

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.
