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.

It could just be the fact that the Fascinate gets crap battery life in general. I get crappy battery life no matter what. Thanks for the useless post tho. Hopefully mine is just as wothless.

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.

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.

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.

Alright, so here's how it goes. I happen to be really anal about battery life, and if I come home from a 8 hour day and I have less than 50% of battery life, it just bothers me.
So, with a bit of reading, I have my phone set up to where I get almost 24 hours of battery life. So here are the steps I took to achieve that:
Have all the basics down:
Be on the lowest brightness (because even that is extremely bright) unless in extraordinary situations.
Always use wifi over 3G/2G and use bluetooth and the GPS as little as possible.
Also don't install any task killers - they do more harm than good.
1. Flashthe Bionix ROM. For those of you who haven't done it yet, you are missing a lot. The speed of ROM is incredible and has a lot of little tweaks that will improve battery life. Don't be afraid to root and flash these ROMS - they have been throughly tested and proved to almost always solve problems instead of creating new ones! Make sure to download the Bionix ROM that runs on the J12 modem. Pick it up here:
HTML:
http://forum.xda-developers.com/showthread.php?t=782027
2. Wipe battery stats!!! This one is without a doubt the most critical. I did this and my battery life increased by more than 2X. Make sure you follow the instructions that state:
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"

To do step 6, I had my phone at full brightness with Bluetooth and GPS on, with Pandora running all while recording a HD video. It drained it pretty damn quick lol.
3. Install Autokiller from the market, and apply the Aggressive preset. This will really lower CPU usage, and really speeds up your phone. This is NOT a task killer, this just allocates memory more harshly.
4. Install JuiceDefender, and have it enabled at all times... A lot of people have had mixed results with this. Mainly, it will turn of data while your phone is asleep, but turning data on and off is a battery drainer. Juicedefender will automatically recognize what settings will produce the most preservation of battery for your phone, so leave it at the default settings. It all depends on how often you use your phone, and what your data connection is like in the areas you reside. It does great things for most people, so I really suggest you try it out. Make sure you download the "battery" version and not the beta.
5. Have all apps/widgets that regularly stream information to the lowest interval possible. Let's be honest, you don't need your Facebook widget to be refreshing every 5min, so set it at an hour.
With all this done, I am at this very moment at 44% battery with a little over 13 hours of use. Even if I had my phone asleep the entire time, 24 hours is a lot better than what most people would seem to get. My day usually consists of 20min of talk time, 30 min of texting, 40 min of browsing, 30 min of gaming, 1 hour of music playing, and a bit of picture taking/editing. My phone is asleep for a long periods of time while I am at school. Yes I don't use my phone as heavily as some do, but if it guarantees me a full day of battery, I don't mind too much.
I don't really see how this can't work for others. We have the exact same hardware, and the exact same battery. You may use the phone more than I and pump out a few hours less, but still get over 15 hours.
Hope this helped!

I would specify what settings you use on JuiceDefender, because it really depends on what settings you use and such. You made this guide to help people, so don't leave them wondering.
I would include other ways to save battery life, even if they have been said over and over, just so no one misses anything.
Also, with Bionix you will probably want to only recommend the JI2 modem, because it is not universally accepted that JI6 helps battery life, in fact it is quite the contrary.

Agreed, I moderately use my phone the whole day and I am left with 25-30% after a 15 hour day. Its not necessary to have max brightness, 3g, bt, syncing, wifi, tons of widgets on all day.
My secret was just getting another battery sent to me. The one that came with teh phone jus wasnt all that great. New one lasts 4 to 5 hours longer doing the same things.
I leave bluetooth on all the time. Never turn it off. Only turn on GPS when needed. And at work where i dont usually get wifi, i leave 2G on most of the time unless i need it to be faster for something, but most times, 2G is fine for tweets and emails. Of course it all depends on how much im using it. I use it if i have to. If the battery is lower than usual when i get home, who cares? I charge it up over night every night anyways. I'm not anal that way.
Most ive got for a day is 18 hours. Had 17 or so many times and had a little over 16 hours today w/ 10% left but plugged it in anyways.
My secret Is to leave the music playing overnight. With headphones.

No, because this phone is unbrickable. You just need average reading comprehension and moderate computer literacy.
On a side note, the recommended autokiller setting is far too high. It kills anything after you exit out of it. (i.e. checking a text, it will kill the texting program after exiting) I lowered a few levels to see if I'll keep it.
added to the thread Mark. You are right, having it at such a high level will not only kill some running apps, but those apps will go onto restart, which kills battery. I think the "aggressive" setting is most suitable, or the lowest preset where your phone is still fast enough.

Interesting...great write up.
So would you say Bionix is the the best ROM for the Vibrant? There are so many ROMS's out there and I can imagine how it would confuse the heck out of those who are looking for the best ROM available to date for our phones.
What are your thoughts?
Ok, first up I am not a developer, not would I know how to develop for the phone.
With that said, I've noticed a repeatable chain of events that I think have caused at least in my own situation poor battery life from certain modems.
I noticed that after flashing for instance KA7 on top of a previous installation of KA5, KA6 or even JK6 that battery life of the new KA7 modem was horrific. My base ROM was usually always Nero or Bionix
Then I completely changed to the new Bionix-V ROM which is based on KA7 and voila, my battery life is great.
Could it be that the process of flashing different modems causes some kind of internal confusion with the phone that relates to undesirable battery life?
Just an idea, but it's like I said something I have been able to repeat, and perhaps others have had the same experience.

I don't know, but I think it's possible. Sometimes, flashing over causes every kind of problems. Why not?
Isn't that the reason why we clear battery memory after a flash? So that there is no confusion. :-\

Reset the battery stats via recovery and after a full cycle or two you probably won't notice poor battery.

I should have added that I ALWAYS wipe battery stats when making modem/ROM changes - following the usual guidelines.
However, my experience still exists.
Specifics:
Nero V3 Running Voodoo+JK6 = Approx 30 hours battery on light/medium use
Nero V3 Running Voodoo+Updated KA7 = Approx 12-16 hours with same usage
Bionix V running Voodoo+KA7 = Approx 30-36 hours with same usage
It's not placebo - it's a measurable, noticeable difference.
i get good battery ;life out of stock ka7 no bloat prolly around 30h and for instance i had bionix and my battery was sucked up llike no tomorrow thats why i am back on stock
I think the PLACEBO may more correct answer, Since JK2 and on battery has been not a real issue. Every time you flash a new modem etc, if you think you need to (I do not think it is all that important) go into recovery and go in advanced and do the clear battery stats and go from there......
The only Time i have ever had a real issue with the battery life with custom ROMS is when using over-clock roms.
Other than that, I would guess you are using the phone different every day, and do not think so imho. That is a more likely cause of battery performance or lack thereof.
with bionix my battery lasted half less
Is has a lot to do with how much battery you have left when you flash a rom. I always flash with a complete full charge and never really see a difference in battery life going from rom to rom. My battery always last about a day and a half with every rom I have tried. Also I have not once wiped battery stats. This is only needed if you do flash with a battery that is not fully charged.

I apologize but take away about 10 hours of just idling while your sleeping at night, that doesn't count... I could keep my phone asleep with no widgets, 0% brightness, etc. but what's the fun?
As long as your phone lasts you the day, or as long as you need it to, you shouldn't be worried about it going for a week on one charge...

exactly.
Your battery needs to last maximum of 15 hours, unless if you work 24/7.
your going to end up charging it at night so why the hell do you care?
I'm curious about the 20+ hour battery life cases if you have background sync enabled.
I just requested a new battery as my old one I believe is going bad. Running JFD --> JK6 --> JK7. Charged battery to 100% while off over 3 days. (Letting sit all day at 25% 75% and 100%). Resetting battery stats tonight and staying at 100%. I'll see how the new battery compares. (My old battery life was 8-10 hours max).

Na I would rather use my phone as it was intended a smart phone. One should get a day out of it Then plug it in at bed time.
yes well after I wiped everything to re install mikfroyo .4.62 to fix an error I kept getting something surprising happened.
At 6 am I unit my device each day. Now it is 11 pm and I had 49 percent left. That is with about 70 messages, internet browsing l, reading some questionablecontent comic, reading the articles on CNET, two calls. Bluetooth on for 3 hours, 3 short phone calls. Reading xda using this app. Sendong a few mms, and photo downloads.
Now Idk wtf happening to get this battery life but it is amazing.
I also use the throttle tweak, netarchy toatmods.4.3.4 more havs, battery increment fix, and have never gotten anywhere close to this kind of battery life.... ever....
Just thought it was amazing

First, you can never judge battery life until you have ran a rom for a few days. THe first few days will always be a lot better or a lot worse. Second, did you wipe battery stats? Or run the Battery Calibration app? If you didnt, you could be getting a false reading, and while your phone says 40 percent, it may be more like 10, and your phone could die any time.
Yes I did the full large techniques.and reset battey stats everytime I flash. and I have ran this donbefore as in I had an issue that I had to re flash the Rom. Nothing is different except I wiped everything this time LOL. I know the whole Rom and battery thing jot my first time flashing not the last.

I would go about 30-35 hours, but with light surfing, texting here/there and phone calls. maybe -maybe some gps but that usually lessoned my hours. under heavy usage i would get 18 hours or so. ...i miss that cm 7 doesn't seem to be anywhere near that.

It's just the cynic in me. But whenever I've seen people post ridiculous battery life like this with a stock battery, I immediately discredit it unless I see a picture of the battery usage.
And almost every time I've seen someone post the pics trying to "prove" their amazing battery life, they either
a) claimed to use a stock battery but were actually using an extended one (people went back through their posts and saw that they had extended
or
b) they had almost no display usage

Well first off, I don't blame you for being skeptical, cuz I used to be too, untill I started getting it. And second, I won't say something unless I can back it up.
Setup:
Rom: CM7, latest nightly
Kernel : Tiamat 4.0.2 / 3.3.7 [both are the best, in my opinion, 4.0.0 breaks cameras, stay away from it.]
Undervolt: Viperboy's bsm -100mv extreme / bsm v2
I don't use setcpu or juice defender.

It's just the cynic in me. But whenever I've seen people post ridiculous battery life like this with a stock battery, I immediately discredit it unless I see a picture of the battery usage.
And almost every time I've seen someone post the pics trying to "prove" their amazing battery life, they either
a) claimed to use a stock battery but were actually using an extended one (people went back through their posts and saw that they had extended

Well that is true but this is my first time. It is the same exact Rom I just had to re flash. And been running for three days now. It is shocking me to. When I get home I will try to get a screebshot of the batter stats to prove the off charge time and battery usage stats..

Look, if you can't keep track of time, that's your problem. I can well keep track of time and have fixed my phone to suite my needs, and able to get 3 hours of emulator play; if you device fails to perform to that task, not my problem. I'm here to provide information and share my stats, as everyone else he does. If you feel the need to post ignorant degraded posts because you may not believe something, then you sir are ignorant. I won't be putting anymore effort into this, so deuces.
How good a single person's battery life is irrelevant. Consistent results among the majority of users is what is needed. The Droid Charge needs to come to Sprint so we can get a day of heavy use easily.

I will not have bickering over battery lifes or outrages claims on this topic..
It is unneeded,
It's really fascinating to me how some people can get over 24 hours of battery life
on the Evo. I don't think I have bad battery life while my phone lasts about 7 hours, but that's at pretty moderate use. Maybe if I just left my phone alone I can get over 24 hours, but what would be the point of that? Just my thought, everyone uses their phone differently so everyone is going to have different battery life.
And its true that the EVO 3D has a bigger battery, but it also has dual core processor and 3D among other things, so I don't think the results will differ much.
Poor signal strength = short battery life.

I believe the newer processor & graphics chipset use less power than those in the Evo 4G so there could be a decent gain in up time.

It seems that many people talking about battery life forget about the effects signal strength, especially if you have several services syncing data in the background.
Personally I find signal strength to be the largest variable in my battery life, not just on the Supersonic but on a Rhodium and a Kaiser as well. I have a horrible signal at my home (no carrier has a decent signal at my home) and with light usage my battery will be dead in 6-8 hours. When I am at work where I get an excellent signal I can spend 2-3 hours on the phone, and receive and review dozens of email and only use about 15% of my battery.
The moral of the story is that the same phone on the same rom with the same settings and usage can perform drastically different in different areas.
I am kind of amazed with what I am seeing, and am wondering if someone on XDA can help me understand this. So I was running CM7.x on my MT4G for over an year, and this past weekend I switched to CoreDroid because I wanted to try out Sense.
I had a bad feeling about the battery usage because the ROM was "heavier" than CM7.x in terms of UI, Graphics (of course because of Sense 3.5). I went ahead and installed the ROM anyways.
Within a couple of hours, I went from being fully charged to 5% battery....it was draining faster than anything I have seen before. I read CoreDroid release notes and they had mentioned about this severely fast battery drain.
Based on their recommendation, I fully charged the phone once battery level reached 5%. This time, my battery lasted about 17-18 hours, and again I fully charged it when it reached 5%.
Now after the second recharge, its been about 24 hours and I am at 97% battery. I didn't believe CoreDroid release notes that battery life will become better after couple of recharges; I thought it was a bunch of bull to get people to install their ROM.
I am glad to say I was wrong Can someone please explain this battery calibration deal to me?

Best link ever; most informative.
- I think everyone loves Dianne now.
- Someone has a flying car already ...
- In the middle of the most intellectual and technical discussion of battery usage that I have seen, someone asks what is the best facebook app - brilliant!
So...
1. Battery stats are calculated differently per phone and OS version.
2. Battery stats reporting is definitely not %100 accurate.
3. Battery percentage is calculated differently per phone and OS version.
4. Battery percentage reporting is definitely not %100 accurate.
5. On some phones, you can override battery charging limitations by 'bumping'.
6. 'Bumping' is not recommended as can shorten your battery life.
They actually did not cover the OP situation where you let that battery go below 5%, although I am always guilty of skim reading. Still, extremely informative and explains a lot of previously posted battery phenomena.

The drain-charge cycles is just a way to calibrate the battery- takes more time to "forget" the old stats, so people either use an app or manually delete the battery statistics so one can start accumulating fresh statistics.
After a few days you get your statistics right, from then on the battery indicator will be more or less accurate.
Battery drainage has nothing to do, really, with how many times you'll calibrate or drain/ charge or whatever. It has to do with how much you use screen on, Wifi, BT, gps, partial wakelocks, apps syncing etc. In other words- use your phone and be assured battery is going to drain. Leave it alone, let it sleep- battery will last a couple of days...

just to clarify, and sorry for butting in, but there is no such thing as "calibrating your battery"... this has been debunked by many people who understand android's Linux kernel and even an android engineer at Google.
the batterystats.bin file is simply that, a bin. it does nothing more than collect dumped statistics of what exactly has been using your battery, how long, how much power those processes used, etc. it has absolutely nothing to do with your phone's ability to display correct information about how much juice you have left - that function is within the Linux kernel which monitors, and controls power throughout the device.
ask yourself this... ever flashed a ROM with say 50% power left on a charge? what happens after your first boot? does your phone suddenly have no idea how much charge is left? no. it doesn't. because the new kernel you just flashed with your ROM is picking up right where you left off.
wiping battery stats is useless. period. it.does absolutely nothing to better battery life. that is fact. that is your phone. that is your Linux platform and straight truth in how it works.
and since it is stored in the data directory, every time you flash a ROM and wipe data, you are wiping the battery stats... so why do you boot up and do it again... I know... good question.

Yep, agree with your comments 100%. After reading the link posted by estallings15 earlier in this thread, the myth of battery calibration was busted
I agree with most that Battery Calibration is a joke, and doesn't mean anything. However, batteries in many devices (not just our Cell Phones) seem to benefit from proper discharge/full charge cycles. In fact, it's usually recommended in things like electric RC cars that you completely run down the battery as far as you can go (realistically of course!) prior to charging; also to prolong battery life. I always notice at least slightly longer use times if I don't always pop the thing on a charger at 75%. But go with what works for ya, and of course some roms DO drain faster than others. And less screen haha
Alright, nobody probably remembers me, but thats okay! Lol
Anyway, my flashing addiction has unfortunately been starving due to being way too busy with work and such. BUT I FINALLY HAVE FREE TIME! Haha,
So I'm still on Froyo, Syndicate's Frozen ROM (Yeah I know I'm two android versions behind). So I was wondering, whats the steps to going to CM9?
My current setup is:
Syndicate frozen ROM
CWM3
Genocide Kernel
EH17 Modem
Don't get me wrong, I'm not new to any of this, I'm just wondering what the exact steps are if theres anything fancy that needs to be done coming from such an old setup? Or is it as simple as:
Odin stock DK28
Root
Odin CWM(What number are we on now? Link please?)
Flash CM9
Flash Gapps?
Thanks guys!
Flash cwm5 boot into clockword mode wipe "once"
Data cache and dalvik
Flash cm9 it will reboot and install the update then boots up during the animation pull the battery go back in and flash the gapps viola cm9

So theres no need to flash to stock / reroot / all that jazz I did when going from eclair to froyo? Haha.
Not unless you wanna update the modem. You could flash the new EL30.tar with odin, flash cwm5, then flash cm9 in cwm5.

Sounds easy enough, Is EL30 modem a big improvement over EH17?

Not bad at all for an Alpha only a few weeks old for us. Minor bugs that not everyone experiences. A lot of us are using it as a daily. Battery life is not good because it uses a lot of resources. It was meant to run on phones with twice the RAM.

Please stop talking about things that you don't understand. Battery life has little to do with the RAM usage. CM9 alpha4 for me is easily goes 28 hours battery life with a 1.5 year old original 1500mah Epic battery. The trick is to prevent wakelocks, I'm usually ~90% in deep sleep. I disable LED notifications, all haptic feedback, notifications for anything that uses push data (Facebook, gmail, email, etc.) I get an extra ~8 hours battery life if I use Juice Defender to turn off 3G data and Wifi when the screen is off. It takes a little delay for data to start again, but that is acceptable to me. If all my push data notifications are turned off anyway, why bother having data enabled at all?
If someone really needs to contact me they can SMS or Call, which causes both vibrate and sound. Otherwise I'll see messages when I too often turn on the phone screen.

I really respect you and all that you do for us but with all due respect, using your phone for more than just a phone on CM9 eats up the battery pretty quickly. Browsing XDA, polling 4 business email accounts, or on the web uses about 50% more battery than it did on CM7. It was mentioned at initial release how it was meant to run on phones with twice the RAM which attributes to it's sluggishness and lower battery life. I know each Alpha just gets better and better and that is awesome but it will be a while if at all that it can compete with something like CM7 for battery life. I am sure with the same setup you have you can get 50% more battery life on CM7.

Agreed I pulled 5 hours of display on cm7 and can't hardly pull 2h 45m on cm9 same setup no wakelocks no sync browsing xda undervolting as far as my phone will handle..nothing helps. Had to get a 3500mah to compensate the gigantic battery usage and am lucky to 5h45m on it over 13hrs uptime. However we all use our phones differently and to you @wtogami you may see no difference, however for others it drops like a rock.

Yeah if you just stare at your phone while the screen is off and dont do anything haha. But even still with my stock battery haha not even 6 to 7 hours it would be dead. with a 3500 it last longer but its not worth it right now.
Once CM9 progresses to CM7 state then it might be worth it. Still ICS requires more ram so yeah your battery is going to die faster because of memory swapping. IDC what anyone says ICS on our phones still would not last as long as GB.
Plus there was no reason to be rude about. I may not be a DEV but I know how Android works with resource swapping and memory clearing.

Hi, I noticed ics charges faster.
I absolutely love when people who don't build the ****, don't know how to, and couldn't possibly in fine detail explain how it functions argue with the people who do. Cause they like, know better. I'd say if one of the EpicCmTeam says the RAM shortage isn't the cause of the excessive battery drain, he's probably right, as he works directly with providing us with the build, on a level none of us understand or have skill in. Kinda like how certain people wanna argue that they know better than a google engineer. That clearing batterystats does in fact change your battery life despite very explicit explanation from said engineer dictating how that file holds nothing more than the statistics displayed to you about your battery under settings.
