Bad Battery Life

I'm getting bad battery using my phone. Can you guys recommend SetCPU profiles or settings, or do I need a new battery? Thanks!

In case you've set a min/max something like 19 (min) to 768 (max), try setting the min quite a bit higher, like in the 200-400 range. See if that helps. Also, don't go crazy setting a whole bunch of profiles. In fact, for troubleshooting, don't use any so you can narrow things down.

245 245 works really well and doesn't make the phone take forever waking up

Screen Off-480max, 19min
Battery 50%-768max, 480min

Not specific to this topic, but I suspect you really see much difference between 806 and 604...
For your screen-off profile, change the min to something like 245. Just try it for a day or two and see what happens.

I too have poor battery life. We're talking down a percent every 2 minutes. I'm running the Droid does rom. I'm gonna try your settings and see how that works.

My battery drains fast too. I stopped using setcpu. When I'm not using the internet I turn it off. Now my battery last a lot longer.

im at 710/844 2**/4** with half decent battery life. but i do stil walk around with a charger
getting linpacks of 5.783 @ 844mhz!

Well a lot of you have seen my posts on this subject but the op asked so...
I have no setcpu installed, no autokiller. The Froyo ROMs are default set to 710mhz and I enable JIT as it helps battery life. You also NEED to calibrate correctly to see best battery life.
CGriffiths86 summed up my long winded version of battery calibration like this...
1. Fully charge the phone
2. Shutdown, boot into recovery, and Wipe battery stats
3. Reboot from recovery and use the phone as normal until it completely dies
4. Fully recharge the phone
With battery cal, no setcpu, and no autokiller, I get 27-30hrs on a full charge with solid use all day including bt music playback, navigation, calls, texting, and minimal web access.
The other settings I use are.
VMheap 24
Screen at 35% brightness

N2...
What about the other 2 settings with JIT? Do you have them checked or unchecked? Comcache? and Dithering?

I dont use compcache (although I have read that it works well with FROYO based ROMS), and I dont enable surface dithering (doesnt add that much crispness to the display to me and takes away from processing power). I dont believe either of these settings will have much impact on battery life though so try them out and if things are still as snappy as you want then MPTY.

oh yeah try turning off auto sync it helps me a bit

Using CELB 2.8, I get about 24-30 hours of battery life with a fair amount of usage.
http://www.techradar.com/news/phone...android-battery-life-should-last-a-day-690439 when Page made this comment, I was at the time convinced that my phone itself was to blame and quite incredulous with regard to his statement. Turned out...he's right, at least in my case. I'd say stop looking at OS settings and focus on the apps you have installed.
I was having absolutely terrible battery life, even with this rom (though at version 2.5 or so), and couldn't figure it out for the longest time. The culprit turned out to be NewsRob, an RSS reader that syncs with Google Reader. I had it initially set up to sync every 4 hours or so, but the default is 1. Somehow, thanks to Apps2SD, when I flashed a new ROM, the sync settings reverted back to the defaults. I finally figured this out and changed my settings to manual sync and battery life has been epic ever since.
Another app that I think was causing some drain was Locale, as it's constantly polling your phone for data about its condition. I stopped using it altogether and am just out the 6 bucks, I guess.
And another thing that helped was completely removing AutoKiller from my phone.

Last thing, there's an app called JuicePlotter in the market which is really good at helping see trends in your battery drain. It's free.

This is gotta help a lot, thanks! And thanks to the other guys for quick replies!

With a full battery in the morning, o usually have about 20% left about now which is 10:53pm EST. I charged all night last night, wiped battery stats this morning as soon as I took it off the charger, and I have 52% right now! And I have used it more than I usually do. I don't know why that seems to have worked but I hope it does the same tomorrow.
Oh yeah, Setcpu set to 710 max, 245 min, screen set to manual brightness at 45%

Go on ebay and search for HTC Eris batteries. For $15-20 you can buy 2 extra batteries with an EXTERNAL charger. I run my batteries to 15% or less, pop it out, put in a fresh (cool) battery, and put the dead one on the charger. No more carrying a charger everywhere I go or using a landline because my cell is about to die. Then your settings don't really matter. Even if you can use 3 batteries in a day, you'll have a fresh one (or 2) charged by the time you burn up the 3rd one.

[Q] Juice Defender

I have heard good things about juice defender, but i have a basic question. It says it turns of data during times, or when certain apps are running, etc...
Now, is the data only internet connection? Or will it interfere with my ability to get texts as well, because that would be a deal break for me.

Data is only the internet. The only things that you'll be missing out on are e-mails, which will still come through based on your schedule set up and when you have your screen on.
Sent from my SPH-D700 using XDA App

Heard so much about this app, tried it and took me only a few hours to remove it. When screen is off, it kills data, so basically apps like K-9 Mail that push my IMAP-idle email accounts and poll other accounts are basically impotent.
Plus the interface is confusing with a myriad of settings and no real hold on what settings stick or what not to set. I understand the concept of the app but it's not for me. With stock rom and mediahub-DRM-whatever-process killed off manually, i get by a work day with 50% left over on the train/bus-ride home, more than enough to do stuff before i get home.

I dave been using juicedefender for 3 weeks and it has maximized my batt an overall of 1.4x. The interface is confusing for those that don't spend time and learn it....its granular.

U can set it to fcetch data on certain time intervals and u can get emails like that
Sent from my Epic 4G

I'm totally happy with it - I'm getting a rating of around 1.7x to 1.9x I know I can easily go a full day on one charge. The default setting of enabling data every 15 minutes is enough for me - I don't expect to get emails that are time sensitive to the point where a maximum of 15 minute delay would be detrimental. And I play with my phone a lot so I'm usually waking it up to respond to texts and it reenables data then anyway.
edit: I'm not using any battery tweaks or DRM disabling stuff. I'm stock except for rooting.

You guys and this juice defender. you use more battery with this because it is always running in the background. i get 45 hours without juice defender or a task killer. 1 day of battery pleasssseee i could get 2 if it was left in standby or more. no drm removed. root, cwm, galaxy rom and kernel di18 & blue minimalism

Oh well f me... If you're getting 45 hours that must mean I can get 45 hours because, you know, our geographic locations have the exact same coverage and we have the exact same phone usage patterns. Wow I feel like such an idiot. Thank you. Thank you for showing me that juice defender, instead of increasing my battery life by a good 6-8 hours, is actually killing it by 21 hours...

That's fine - always be skeptical especially when an update comes out to improve performance. I'm about to test the new kernel without this to see if it's worth it. But I know that keeping data off on my Hero tripled the battery life and since having this phone it's definitely increased it. But you can't tell me that I'm losing 21 hours of battery life by using it - and definitely don't try to make me feel like an idiot for using it either.

Im sure its not killing you by 21 hours. prolly your STOCK sync settings though. i only turn it on for a minute or two 3x a day. but go with out it i bet its prolly like 8 hours. think about it when your screen is off it is running. well that is another process that is draining battery unneccessarily. My entire phone is set up like on demand it does what i want it to when i want it to not when it wants too and all of this is acheived with stock settings and checking every app for update frequency settings. I use my phone a lot so i need it to be there.

So for argument's sake, and because I wanted an actual test, I installed your setup based on you're post earlier, andromeda rom, no juice, etc. gmail and facebook sync off. I even went in 4 times throughout the day to turn off running services. I got 11 hours and that was with charging while I was in a vehicle. So I would say about 9 to 10 hours really. TWS was only at 16%. Display was the biggest battery drain at 82%.
So now that I've done this, I can say without a doubt, for me personally, juice defender is really extending my battery life. While running juice defender, I take my phone off the charger at 6am typically and when I go to bed at midnight I still have over 20%. And if I don't plug my phone in, I can wake up at 6am the next day and the phone is still on.
You have a setup that works for you, and I have a setup that works for me. In my setup, juice defender gets me through a 24 hour period without charging. Now that I've got the andromeda rom and kernel, I'm going to test battery life with juice.

45 hours is meaningless when you just let the phone sit in standby the entire time. That's like the car commercials that list higher mpg than they get in the real world.

I have juice defender installed only for it's two toggle widgets. With defender disabled it doesn't run in background, I take advantage of the data toggle widget and I've seen it save as high as 5x's life.

Battery

I was wondering how I could extend that battery life on my DINC? Any suggestions and tips would be great.

Ah yes, the battery issue. One I am all too familiar with.
Easy:
For whatever reason our phones charge to 90% and stop there. To correct this, you can either charge while the phone is off or do what we call a bump charge. Bump charging involves charging the phone to "full" while its on (the light should be green) and then turning it off while still plugged in. The light will then change to orange again for 30+ minutes and then green again. You will then Really be fully charged.
Also make sure you have GPS and Bluetooth off when you aren't using them. This will help a ton.
There is an option in Settings - Wireless & networks - mobile networks - called "enable always on mobile data". Unchecking this will drastically help save while the phone is asleep on the 3g network. However, doing this will affect how often you receive updates to chats and sync items when the phone is sleeping. To me it isn't a big deal since if I'm not using the phone why should it be working, but everyone is different!
Finally, a rogue app might be nomming away at your battery. An app from the market called System Panel will monitor how much battery each app is eating. Its free initially but if you want it to monitor over time in the background it does cost. However it is definitely worth it since its a great app and useful for any android owner.
Intermediate (has cost):
Evo batteries fit in our phones! The fit is a little tight but it works just fine. Our stock batteries have 1300mah of capacity which is a bit on the low side. The evo battery has 1500, so it's an hour or so better. You can buy them cheap off ebay (OEM Evo Battery) for around $15.
Conversely, there is the official extended capacity battery for our incredibles with a massive 2150mah. The trade off is that it adds bulk to your phone and costs a lot (around $50). There is the third party seidio battery which adds even more capacity (3500) but adds even more bulk.
Advanced:
Are you rooted? There are kernels out there that are undervolted like Hydra kernel, adrynalyne's undervolted and kingklick's voltage scaling kernel. Everyone has differing experiences with them so there's not a solid "best" so to speak. You can flash these kernels using the clockworkmod recovery. This will all be nonsensical if you're not into the Modding scene.
Also if rooted, you can underclock the processor which, depending on the kernel, can help drastically save battery. You can set profiles to have the cpu work at a minimum speed while the screen is off. Kingklick doesn't advise using setcpu with his kernels and it straight up wont work with hydra's, but it can do wonders on any others.
--
Depending on your activity, you should expect 4-5 hours of 3g awake usage and around 5-6 if you're mostly on wifi using the stock battery. 3g can be a battery drain if you're in an are with inadequate service.
Hope this helps!

turning off gps doesn't matter all that much. GPS isn't called upon unless you have an app using it. I have mine on most of the day (for tasker profiles) and have no issue.
Use WiFi when available, its quicker than 3g and takes less battery.
download setCPU (from xda) and make a profile for screen off max/min = 400/245 or something like that.
i have 'always on data' checked, no issues for me
kernels help a ton, kk#5 is a beast.
I'm running uncommon sense, kk#5 and the above settings. I'm on 20 hours unplugged with 35% less, standard usage. -- not bump charged, charged while on to 100%

isn't the system panel app like a task killer? and from what i've read task killers are pretty pointless with froyo......however i have noticed that my phone is constantly running with about 140mb of ram free, i don't know if this is usual or if something is wrong?? i just got my Dinc so i'm new to all the tweeks and tricks, i do have mine rooted though. i'm not that up on changing roms and kernals though so i'm just trying to find out what all i can do to help my battery without having to buy a bigger one. any help would be greatly appreciated!!

If you are rooted and aren't comfortable with flashing ROMs and kernels, look at setcpu that was mentioned before, and search for instructions to remove the stock apps that always startup on their own in the background. Unless you actually use them, then you can't really do that obviously. I don't have any times on how long it lasted before and how long it last now but I do know its improved. I have mine at a processor clock speed of 500mhz and I don't see much lag time unless I'm really running a lot of things. I'm on WiFi listening to Pandora and I'm not experiencing keyboard lag while typing this.

no...the max it'll run is 1.19 ghz. worst that will happen is a bootloop which can be fixed through nandroid.
Just increment a little at a time. I usually run mine at 1.075 ghz w/ on demand.
screen off profile max/min - 450/245

I use JuiceDefender on my Incredible and believe it or not it really works. It's turns off your data while the phone is on sleep mode so no battery is being drained. I get at least 5 hours extra battery life. You also get other features that come along with it so just give it a try It's free!

Yes system panel CAN be a task killer but I do not suggest using it as such. Instead, it does a great job monitoring how much CPU each app uses so you can take educated action.

1. If you use location based services and have GPS on, it will use the GPS module quite a bit. This is certainly a battery drain.
2. If you dont have any issues with always on mobile data then you must be in an area with good coverage. For me if its left on it drains my battery quite a bit because I'm in a flaky coverage area.
Everyone's phone is different though. Finding what works and what doesn't is the first step to perfection. I just installed the new skyraider sense and my battery life has been ultra fantastic. It works great for me, but I know others dont have that success.

How To Get At Least 15+ Hours of Battery Life

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.

Aside from steaming pandora all day I'm doing all that too. Wifi always on, gps navigation, watching youtube/nfl app videos, twitter/email throughout the day, forums, etc. The only way I can kill my phone anywhere near that fast is hours of constant video steaming over 3g
Edit: oh, and angry birds all day every day, haha

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.

thank you! I will try this out. =]

I wanna put Bionix on my phone so bad, but if I screw up and brick the phone, then no more Vibrant for me. :/ need a better job imo.

It's really hard to screw up. (assuming you have made it though an educational system successfully)

Hah, I think I'm taking this as a personal challenge. How about if I DO screw up you send me your Vibrant? Deal?

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?

[GUIDE] How I got almost 3 days of battery life on my Nexus S 4G

First and foremost this guide is based around the Sprint Nexus S 4G. If you do not have the Nexus S 4G, Than this guide will probably not help you. =)
Secondly all credit goes to the wonderful people that work endlessly to make these wonderful Roms and Kernels. Without you guys Android wouldn't be what it is today!
Third: Please make a back up and use this guide at your own risk. I don't want to bare the weight of someone turning their phone into a paperweight by using this guide.
Alright, Now lets get to the fun part.
Case you've already forgotten why you're ready this topic. This is my rough how-to guide on getting easily over 2 days out of a single charge on your phone, Very much possible to push 3 or more days depending on use and other varying factors.
What you're going to need to start:
- Rooted Nexus S 4G with a custom recovery like Clockwork mod.
- Flash the following Rom http://forum.xda-developers.com/showthread.php?t=1417499
- Flash the following Kernel http://forum.xda-developers.com/showthread.php?t=1436313
-Flash the following "KL2" Radio update http://forum.xda-developers.com/showthread.php?t=1077168
After you have flashed all the above and confirmed your phone is running stable with all the default settings. Charge your phone to 100% and reboot back into recovery, and WIPE YOUR BATTERY STATS
Now. Lets begin configuring your rom and kernel!
- Install CPU MASTER FREE from the android market https://market.android.com/details?id=com.antutu.CpuMasterFree&hl=en
Set the following on CPU Master
- CPU Speed 800 MAX and 100MIN
- CPU Governor CONSERVATIVE
- and Scheduler set to CFQ
- Make sure to click apply on boot as well
- Now Install NSTOOLS from the Android market https://market.android.com/details?id=mobi.cyann.nstools&feature=search_result
Set the following on NSTOOLS
- DEEP IDLE: ENABLED
- Backlight Dimmer: ENABLED
- Make sure Backlight Notifications are left disabled. It keeps phone from idling properly.
- Leave all other settings alone and make sure to check set on boot
- Now lastly install Antutu Battery Saver from the Android Market
https://market.android.com/details?id=com.antutu.powersaver&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5hbnR1dHUucG93ZXJzYXZlciJd
Activate Battery Saver and set to level 2 battery save. Easy as that.
Basically your done! =)
If you notice your phone has a slightly worse or little to no improvement on the battery this is due to you deleting your battery stats. As you use your phone it will write new stats and you will begin to notice a difference after a few cycles. Just make sure your battery is charged when you wipe them, Let the phone run almost completely dead. Plug it up, Let it charge back to 100%, Unplug it. Rinse and repeat. Just be sure to unplug it when you notice it's fully charged even if you don't plan on going anywhere. Just let it sit and run on battery so that it calibrates the battery stats while it's idle as well.
Now as you should already know your battery life is going to heavily depend on use and SIGNAL STRENGTH. It seems a lot of people don't realize the more signal you have the longer your battery will last. If you're in an area with very low signal it can kill your phone in a matter of hours.
I have attached a screen shot of my battery life using this above method. Other settings I will mention
- WIFI ENABLED and CONNECTED
- Bluetooth and NFC DISABLED
- Automatic backlight control enabled
- Facebook notifcations, Weather and Contacts are the only things set to SYNC on my phone.
- Usage: Light to moderate. This includes a few texts throughout the day. A few phone calls, and a brief checking of facebook every now and then.
If I'm missing anything I will update this post. That is all for now. Happy modding and may this tutorial work the same wonders for you as it did me.
Also I should state that the phone finally died at around 2Days 17hrs on battery. My goal for 3 straight days was cut short after a few 30 minute phone calls and other work I had to do on the phone.
If you have any questions. Feel free to post, or PM me. I'll be here =)

I thought it was the More Bars you have the more Data Kills Your Battery... but sprints 3G sucks .. some users only experience a .5kbs to 1.0 Mbs (if your lucky) ... that being said I think that's why your battery lasts longer. But then again I'm on Wifi so my battery has lasted all day ^_^ 15% left. Nfc on , Bluetooth off , screen at 50% brightness and heavy usage. Buuuut in your screen shot below your on 3G ... the 2 days.. was it always on Wifi?
- Google

What is your screen on time?
I don't use any "power-saving" apps, just AOKP Milestone 2 with Steve Garon's 1.14 kernel to run 50hrs with nearly 4hrs of screen time.
100/1100mhz, interactive governor, standard voltage, bln/bld on, wifi used whenever available. It doesn't help that my office is in a poor signal area - battery life would be much better if the signal reception bar stayed green all the time.

Screen time out is on 30 seconds. and Wifi was connected virutally through the entire time, exception was when I visited a friends house which is why in the screenshot it does not say it's connected, However it was still active.

Those are very nice stats, Question, On your battery log, What are the massive drops in battery from? low signal or just heavy use on your phone?
Also I believe I'm going to go back an retry my experiment with SmartassV2 governor and On Demand. because I recently read they are better than conservative.
By all means play around with these settings and if you report back something I can approve on I will be happy to update this post and give credit to whoever finds more tricks to improving the battery life even more =)

They're from heavy use, probably angry birds or web browsing. The poor signal usually results in much slower drain.

Not saying you're wrong, but based on past experience when I lived in an area where my phone was constantly losing and gaining signal or especially switching between Verizon (Roaming) and Sprint to find a signal, My phone would get very warm and it would cause massive battery drain.

Also in regards to the Sprints 3G speed.
Here in town where I live now, with the new KL2 radio
Edit:
I have attached screenshots of 3G speeds. It seems today when I ran the test the speeds aren't that special, I guess it all depends on network load.

I can get about 4-5 hrs on screen-on time a day with a full charge before it dies. I couldn't imagine spreading that amount of time over three days unless I was travelling again or something lol

Haha yeah sorry about that guys, That could have been helpful for me to post, but I actually just now realized you could view your screen on hours by clicking it. I feel about stupid now.
After I tweak some more settings and do this little experiment again I'll be sure to actually include that, Seeing as it would have been helpful LOL

How do you get your phone to idle so well? I can never get the battery stats to flatline like that. Could it be due to me having BLN turned on as the OP said that causes an idle bug?

There's a possibly you're running an app in the background that's preventing your phone from deep idling. Also try the battery saving app I mentioned in the post as well. It works wonders for some, and others don't notice difference. There's a lot of varying factors.
Have you wiped your battery stats and calibrated your battery with the method I mentioned above? Also you can check to see if your phone is deep idling by going into NSTools and clicking Idle stats.
If you see that your idle numbs are higher than your deep idle stats, Than yes, Something is preventing you're phone from doing so, and I would recommend disabling BLN and seeing if that fixes it.
It could be an issue with BLN and it may not be. My entire post is basically the steps and settings I've figured out and tweaked on my own to achieve maximum battery. I've read around and it seems some others have used BLN without any noticeable difference in battery at all. I guess it really just depends.
Also to the other post, The main reason I run my phone unclocked is basically, in use, I prefer the CPU to be at the lowest max speed possible, while remaining smooth, and I've noticed no lag at 800max, So therefor even when I'm using my phone it's still not going to be pulling as much power as if lets say I had it set to 1000 or 1100. Overclocking is great, Don't get me wrong, but unless you're doing something heavy like gaming or a sheet ton of crazy multitasking, I don't really think it's worth it. That's just my opinion though =)

So you're at home all this time? Then why go through all this trouble and handicapping of features and performance? Why not just plug it in?

How exactly am I handicapping? I had people asking me how I was getting my battery life and wanted me to post up details on it, so I decided I would. I run an underclocked phone because like I stated in my previous post, I don't see the point in running a overclocked phone unless you're going for benchmarks or doing a lot of heavy multitasking and then by all means, Take the 5 seconds to change your max CPU speed. If you're referring to me not running BLN, That's because for some, including me it keeps your phone from idling and will cause battery drain. It works fine for some, others it doesn't. I'm SURE it's a problem on my end, but until I get it worked out I'm just leaving it off for now.
I've been learning about rooting and modding since the Sprint HTC Hero days. I'm far from a professional and will be the first to admit I'm an amateur compared to you guys, I cannot develop, I cannot code. I'm simply wrote this guide as a reference point for people wanting to get good battery life, That's why I said tweak with the settings and have fun.
The main reason I'm so ecstatic about the battery life, is up until now I've barely been able to get a days normal use out of an android phone even running custom roms and all that good stuff. Now I can actually use my phone throughout the day, Throw it on my dresser at night, and wake up the next morning with still enough charge to use it again without having to worry about plugging it up every night.

Home or not, this info can prove to be very useful depending on an individual's circumstance. I work multiple jobs and when I get home, sometimes I'm so tired I don't even bother to fiddle with my phone's charging cable and just crash on my bed. I've gotten great battery life using similar tactics (went to bed with a 13% charge once, woke up with the thing still alive and kicking), so again, some may find this extremely helpful. Good work!
