Battery problems? Google lies?

So I found this great app that tells me how much life I have left on my battery. I find that with my phone I can hardly go pass 16 hours with MODERATE use yet everyone here is bragging about easily passing 30hrs with HEAVY use. So I'm asking you guys, to please, download this app called BatteryTime Lite and post your pics or info here. Lets compare the results. Remember to set the level to 100% as shown in my pic below..
Also I herd the P/N might be related, mine is 99HKE002-00 F ..Guessing F means Failure.

Are you using Cyanogen's ROM???

No, stock. Why you ask?

i read somewhere that Stock and Cyanogen's ROM have display consuming a lot of battery... its fixed on enomther's and modaco's desire port...
On Cyanogen and Stock, Display consumes ~60% battery while on Enomther's and MoDaCo's desire port, display consumes 15~20% battery...

Thats what I herd too..thats why I'm also calling google a lier about saying this thing lasts 20hours with audio playback.
I'm curious, do they see a big improvement in battery when the display using 15-20% battery or its just numbers that were out a place to begin with?

I have identical figures. That combined with picking the N1 from a list says to me that these are just database figures rather than real world ones for your handset.

Root your phone and then install cyanogenmod and one of the under volted kernels. I usually get 24 - 30 hours battery life.

I just ran a test. I left the mp3 player on all night turn all the way on repeat. SO far after 8hrs of playing I was at 52%. If I'm correct, I just might be able to hit 18hrs...MMMM

Completely far from the part that I said google lied. Though I'm planning to root if the next update does not improve or fix these issues.

No problems at all? no 3g issues?, battery only lasting a day or half? or touch screen issues?

Ok after 100% charge..the app is telling me that my phone will last 10hr:48min with moderate use....anyone thinking that the F on my P/N might mean battery sucker..

i have the exact same numbers as you. if you choose other instead of the phone type it asks you to enter your battery's info so it sounds like it only goes by the type of battery anyway. Not actual usage specific to your phone

My phone ends in an F as well. My battery life SUCKS right now. I have tried everything. The weird thing is it was good until I rooted my phone and applied Cyanogen rom. I've tried .2 and .3 for the Cyan rom's, all with bad battery life. I've tried wiping batterystats, fulling draining battery then recharging, task killer to wipe anything in the background, I even have a 2nd battery. No luck. I've also tried the undervolted kernal, but I didn't really notice a difference with it. (Only tried it for about a day so)
Bottom line though, something is going on. Something (I suspect with Cyan's roms) is killing battery life for some of us. I just wish I could figure out what it is.

Beautiful phone with bad battery life and bad signal.That was just my experience.

Any chance you're using Weatherbug or Weatherbug elite (based on your SS)? After installing weatherbug and using the widget I got absolutely ABYSMAL battery life. I've purchased several other weather widgets and none had the effect that Weatherbug did for some reason. I removed it and battery life is back to normal again (moderate use and plenty of battery at the end of the day).

How long your battery lasts definitely depends on the apps youre using, I use my phone a lot, probably more than the average user, although i dont make many calls. My phone will easily last from when I leave my house around 530am till 11pm or so when I go to bed. I do use a task manager to kill stuff I dont need running every once in a while, I think it really just depends on how you use it. I use it for a lot of texting, surfing and news, and Pandora at work. I use wifi when im at home although ive never noticed it eating my battery. Yesterday I was playing Pandora over bluetooth on 3G for a little over 3 hours and it only took 5% of my battery. Im on Cyanogen 5.0.5.3, if that matters. With all that said I rarely go all day without charging it, I usually plug it in a bit at work and plug it in when I get home, but if I dont for whatever reason it easily lasts my whole day.

I'm just gonna say...(Batt issues)

Before I was a behavioral therapist I worked for a small (lol) company called Applied Materials. And there I worked as a project manager. And what I learned there was the importance of following procedure, something most here seem to fail doing. I know I'm not the only one tired of seeing at least 2-3 threads a day pop up complaining how adryns or blah blahs rom is giving you horrible battery life. Have you stopped and thought for a second that it may have something to do on your part? Let me rephrase that, it is something to do with you. There are procedures before flashing...for example, flashing on a full charge is ALWAYS recommended. Second, wipe wipe and wipe again. I hope you don't wipe your ass the same way you do your phone. You stop to think for a second that flashing two themes a day isn't going to f things up with your battery if you're not following proper protocol? Why is it some people don't have issues and some do? It's simple, you f'd it up.

And for the record, the reason I posted this is to stress the importance of following the rules, bc when there really is an issue, it's like "the boy who cried wolf". We don't know which is legit and the other is just some kid too hyped to get that blackhole or superclean and cuts corners.

This thread drained my battery real bad.

The fascinate is proven to get better battery life then the droid amoung many other androids. I get maybe 16 hours of heavy use. I've been on this forum all day running superclean 2.1 with voodoo and still have 37% left...yeah that's some ****ty battery life for ya lol
Edit: maybe the majority of us getting around 15+ hours are just on some really good dope.

Droid? Which droid? Certainly not the Droid X, I had one and battery life was way better. I dont know anybody that gets more than 10 hours on heavy use. Sure you can get more if you dont actually use your phone as a phone.

Lmfao...really? Then why is my cousin who has an x charging his phone while im sitting here on his couch still posting. Before you post again take a peek...i've been trollon this forum for 12 hours now.

I followed everything to a T the second time around. My first time flashing superclean I was getting less than stellar battery life. Second time around I wiped data, cache, dalvik, and battery stats multiple times while on a full charge.
I've had my phone off the charger for 13 hours now and I am at ~60%. I haven't used it as heavy as normal, but even under heavy load I am getting much better battery than my first time around.

In "16 hours of heavy use", how much of that time was your screen active? You can look in Settings -> About -> Battery Use -> Display. "Heavy use" is a fairly imprecise term, since what one person might consider heavy use might be 'fairly light' to another.

All right, I have to admit, that right there is pretty funny!
I agree with your post, thought. Every time a new rom is released, the next several days are filled with complaints about the battery life. If you follow the procedure for resyncing the battery stats, your battery life will be back.

I get good battery life...so this isn't a fact for me.
The most important thing to keep in mind is battery life is SUBJECTIVE, as are the terms used to define usage (including "good" and "crap" as in the above). What one person considers "light/medium" use might be "heavy" use for someone else, and vice versa.

For me battery life on eb01 is great as long as gps isn't enabled in the pull down shade. When that is on the phone doesn't sleep even if gps is never showing active in the status bar.

X3...imho, it's an irrelevant feature to have on at all times unless you actually need it.

Eb01 battery life is sub par - mostly to with the fact we do not have custom kernels yet. Wait for those and well see the battery life that spoiled us again.

Not percentage, but time.
My Fascinate, currently, has been unplugged for 22 hours. Light/medium/heavy use is all completely and totally relative and opinionated terms. The amount of 'Time on' for the screen is a fair bit better way to show the use than just the meaningless 'heavy' & friends terms *. I've had my screen on for 55 minutes total, during those 22 hours, and am down to 42% battery life remaining. I wouldn't call the use I'd done 'heavy use', but someone else might consider that about as much use as they've given their phone in a WEEK!
I find my battery life is decent, but by no means amazing (I generally always make it through a day, 2 with light usage).
* Even then, it's a fair bit different if the time was spent looking at a single active pixel on the screen, vs playing with an augmented reality app that keeps the GPS, camera+flash, and wifi/3G constantly going, while also burning huge amounts of cycles on both the GPU and CPU... but one step at a time.

Okay, I've been flashing my ass all day long and not one person has mentioned seeing a wipe button appear, so I don't see how anyone can wipe their ass the same as their phone.

In my case it's mostly due to the fact that the phone never sleeps if GPS is enabled. When the phone doesn't sleep, it eats battery at an alarming rate even just sitting in your pocket. Once GPS is disabled in the notification shade, battery life is more in line with DL09. I'll be happy once we get some custom kernels, as a LV kernel seems to help my device a bit, but battery life isn't so bad anymore as to cause me to flash back to DL09.

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!

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.

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.

[ICS] We need your help... Battery life...

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

Eclair

But seriously, disabling 3g on ICS saves a ton of battery life.

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.

He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.

PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.

Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.

3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.

- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
