theres 2 main questions, are you using sbc or a wall charger and two, who makes the battery

and if its a non-seidio, some of them just plain suck. i've bought 4 different ones from ebay/amazon only one actually works well after calibration and many cycles of usage.

I am usung netarchy sbc

You need to condition your battery
I've been dealing with this for ever and I thin kI finally haqve a routine figured out that is getting me CM7 like battery life on a Sense ROM.
1st, I've had the Sedio 3500 for a few months, and like you, I was getting ridiculous drain, until I started sdoing some reading and experimenting.
Here's what I do.
First, off, I have GPS, WIFI and Data disable all the time, unless I need one of them, and then I turn off again when I'm done. I keep my screen off all the time, unless I'm using the phone. I also only use minimal widgets. Calender, Fany Widgets Weather and Forcast, Messages widget, the Beautiful toggle widget for silence and my MIUI Music player on 3 screens, using Rosie. The other 4 screens are just empty.
Second, as for the battery itself, charge the phone for about 8 hrs, and this is the HTC method, unplug it, turn it off, and charge it for another hour, while off.
Unplug it, turn it on for 2 minutes, then power down and plug it in for another hour.
Now, before powering I up, I do the Hoodoo-voodoo-like 10 time unplug thing.
Basically, unplug, light goes off. Plug it in, light is red, wait til it turns green, unplug it and do this 10 times.
Reboot to recovery, wipe battery stats, power up, all while plugged in, and once fully booted, unplug.
I did this today, using the new Koni 3, with Netarchy 4.3.2 SBC HAVS, and riding then used the phone pretty steadily to play Klondike, text, etc an an hour later was just dropping to 99%.
THAT is pretty good, compared to what it used to be like, when it would drop about 1 percentile per minute, even when it was in sleep mode.

Reconditioning is not going to work when you buy a crappy battery. Someone said voodo? You're kidding, right?
Please understand there is no regulation that prevents people from stating their cheap batteries on eBay are 9800mAh but only providing 1000.
I bought 1500mAh eBay batteries that are only 900mAh, verified with equipment.
Check www.batteryboss.org to see what I'm talking about.
Best thing to do? Buy a $1 battery wall charger, two OEM/non-generic htc batteries and carry in your wallet. I wouldn't be surprised if your 3500mAh battery actually packs less juice than the original battery. Oh and your phone is looking like a brick for nothing.

yeah this is why i asked, if you bought a very cheap extended battery, well its rating is different than what it is providing you with

I think I have battery problems solved; Just turn Data off when you're not using it. My phone has been off the charger since Friday night @ 6:30pm. Now it's Sunday @ 9:30am. That's 39 hours and I'm sitting at 63% and I've been texting, making calls, playing a few games, and anytime I need data, I just turn it back on til I'm done and then back off again. That's the only thing I'm doing different now, and before I made that little change, my battery was a good or bad as anyone else's

When I am home, I have WiFi enabled all the time, no 3G/4G. I heard WiFi is better(with good signal) for your battery than 3G enabled. Is this true? My battery lasts about 7-8 hrs of moderate-heavy usage.
Also, here's a thing with all of you trying to tweak your battery to get best performance. From my own experience, I am never a step or two away from a charger be it while I'm on my computer at work, at home or in the car. So what good is it to have the phone out of the charger for days?

I understand WiFI is better, too, from what I've read.
Also, if I can find it, I found a thread on androidfrums from htc that recommends you let your battery drain to below 50% before charging it.
Like you, I have chargers all over, so it's not a big deal, but to be at where I am now, with this experiment on turning data off is simply amazing to me.
Almost 42 hours and at 59%

That is definitely a huge performance improvement but I wonder what's happening with all your apps that need the data sync in the background. I have apps like Pulse, Facebook, K9, Handcent, etc that update every couple of hours or have "push" enabled. What is the trick to allow 3g, 4g, wifi to be enabled automatically only when sync is required and then disabled?

Good question.
All I use is the weather bug and Fany Widgets weather, ad far as widgets that need updating. I think, once they try to update and can't connect, they "freeze" for lack of a better word, until you reconnect and manually update.
It's a little bit of a pain, but for this kind've battery life, I'm not gonna complain

I think what would work is an app that puts the phone in "Airplane Mode" (bad Moment memories ), but allows the calls to come thru. This way there's absolutely no Internet traffic but your Evo is still usable as a phone.

That's probably, basically what I'm doing, but like you, coming from the Moment, Airplane Mode is a bad word....

I've tried all the hottest kernels and battery saving tricks and still average only 8hrs under real world use
Running Evo Deck 1.2.1, display at 12%, couple widgets, data off (using wifi at home) , sync off, and all of that. Underclocked, undervolted too.
Browsing, xda app, etc results in 20% battery usage per hour. Battery consumption is zero at idle, but drops like a rock if i use the phone at all.

Battery calibration is very important, don't know how I lived without it
Setting the VM heap to 48 allows the dalvik garbage collector to run less, improving battery
Chainfire 3d helps with anything graphical, makes home using lwps smoother, games run better etc, also saves battery by making all animations, graphics processing more efficient
If you use apps2sd bumping the cache makes it faster, and more efficient saving battery
Also updating to the latest radios etc, and making sure your prls and profile is up to date is essential, many aosp users, formerly including my self forget about that stuff
I've spent a huge amount of time expirementing with different setups, I think I've found my phones sweet spot
I have loads of friends with rooted evos, mine has the best battery and is typically fastest (chainfire 3d) makes everything snappier
Maybe with all of this info you can test these apps / settings and find your phones sweet spot. Good luck man

I'll agree with Zac here,
evo 3d with CM7 nightly, SavagedZen 2.2.1 CFS. removed all the crap i dont use or think they suck the battery down. live wallpaper etc.
InteractiveX governor, 245-1113mhz
No setCPU.
no juice defender
no taskkiller.
no 4g - no gps - no wifi
blutooth ON
3g always ON.
battery calibrated is a must
display set to manual around 33% brightness. but i change it on the fly (swipe the notif bar).
Now the results are pretty interesting here:
With the stock battery and all the above; if the reception is good, i can go for 2 days with moderate usage. yes i know i night i sleep, so it idles nicely.
If the signal is not so good, it will destroy the battery, and can't really get anything more than 13hours.
My typical use:
unplug at 10am.
use the phone normally.
plug it back in at midnight that night, and i would have between 35% or up to 67% battery left in the phone, depending on the factors mentioned.
Which to me, going all day is all i wanted before i started tweaking. Mission accomplished.
The quality of the reception is a killer, i'll tell you.

I bought a 3500mah battery from the same company, and it is trash.

are there any extended batteries that fit in an otterbox commuter case?

How do you maintain your battery?

No problem for the link. There are many ways to help save battery. I for one turn off GPS, Bluetooth, and mobile data when I'm not using them. I use AOSP Roms mostly because they give me better battery life, I use Incredikernel because it regulates how my battery works more efficiently, and I also have an extended battery. Wiping your battery stats every once in a while can help you prolong your battery life as well.
Sent from my ADR6300 using XDA App

optimized sense with the stock kernel will warrant some seriously nice battery life. thats how I maintain mine.

Depends on what I do, through a normal day (texting, few short calls, 30 minutes of music streaming, less than 5 minutes of GPS) it'll last ~1.5-2 days with CM7 nightlies and chad's incredikernel - underclocked 128MIN - ~800max
But if I use GPS all day, which I sometimes do- it'll drop 50% after 4-5 hours of use (this means screen-on, GPS running, also uses 3G data for maps) and I'll usually need to plug it in before the day ends.
I have a 1900mAh battery that fits in the stock case, so this isn't what I get on the stock 1300mAh battery.
If you can't last it through the day it usually means that you are a very heavy user (you like browsing the web all the time, streaming music, texting, watching videos) OR you have a setup that likes to eat your battery.

I need two of my 3 batteries to make it through one day. I use juice defender, and when I stream pandora at work I turn it off cause it interferes. I always have a charger handy too

I actually didn't know that the 2150 was smaller than the 3500. That thing is a beast, my friend uses one and his phone is at least twice as thick as mine.

If you are rooted, you can update the radio, I've noticed much better performance out of the updates cause they seem to manage gps and wireless better. The radio update turn off wireless if you are out of range and turn off gps if no app is using it.

yeah but you have to take into account how slim the stock incredible is. Without any case and with only the stock battery it's too thin (for me at least). Hard to hold onto the sides and I accidentally press the volume buttons often. I've also dropped it 3 times with that setup.
With a case it's great and with the 2150 it was great, loved both setups but I'm liking the new style now with the 1900 and case so that's where I'm sticking at.

Does wiping the battery stats help the battery life? Or is it just so the phone better understands how much battery is left?

Stock battery has always worked best for me.. I also have the seido 1750 mah as well as some chinese versions of 1500 mah.. I use them as backups.. I'm currently using miui as my rom and the battery life is great... I usually get about 24hrs before i'm down to 20%. No way I would make the whole day on previous roms..

I take cues from battery university. Basically, don't let the battery go below 20% shallow charge /discharge

I strive on my battery. Using cm7, I make sure everything is toned down and my interface is set at night mode. I was thinking, since I really never need nights on my keyboard, how much more battery would I save by them completely disabled!? They stay off when my battery warns me, so surely their should be a way to rid them all together.
Sent from my SPH-D700 using XDA App

My god how can you stand night-mode colors all the time? There isn't any functionality for changing the keyboard backlight timer in CM7, it will typically stay on as long as the screen stays on. All in all I don't think it will make a huge difference on your battery since it needs the screen to be on for it to be on and the screen uses way more battery. I doubt you would see any major increases in you battery life anyways, considering you're pretty anemic on your battery as it is 0_0

Ultimate Battery life solution (one of many)
here is what i did. I invested in the donate setcpu app on the market. Of course you need to be rooted in order to take advantage of this.
Make a profile for "Screen Off" and underclock your processor to max = 200 and min = 100, and set the priority high. That way, when you are sleeping or not using your phone, while your screen is off, ur processor has absoutely no reason to work hard, and therefore will drain your battery VERY little.
Try it, I tested how it works, and had a 100% battery life when i went to sleep at 11pm, unplugged my phone and turned off my screen, and when i woke up at 7am still had 100% battery life.
oh, I'm also on CM7 as well, i'm sure that's helping too. haha

I do the same on my tw rom and I go to sleep at 100% and wake up at 100%... if I go to sleep at 80% I wake up with it still at 80%... underclocking the processor while not in use works very well to save battery...

Juice defender works the best,what really kills the battery is screen brightness and 3g/wifi/4g data syncing in background for apps that require data.Use juice defender and set profile to extreme,when phone is on standby mode it will turn off radio until you wake the phone back up

Best thing I have found is to totally drain battery to the point it the phone will only slightly vibrate. Remove the Battery. Put the battery back in and then fully charge with the phone on charge mode to 100 percent. Unplug. Then plug back in a few seconds later for fully charged to reappear. Done. Really helps to do this once every month or two. Credit to someone on another forum for this tip. Turning off data when not in use and low screen brightness will substantially increase battery life. No syncing, bluetooth or wifi will help. An app called GSam battery monitor will identify apps that suck battery. I use longevity by trend micro to shut my data off.

Fully draining a lithium ion battery will significantly decrease it's lifespan. Any positive effects you see from this are probably not measurable, or scientifically reproducible. Your other tip is solid, disabling data (or using an app to do so) greatly increases battery life. As well as turning down the brightness.

Battery lifespan for lithium ion batteries is measured on how many cycles its been through (hits 100%). If you go from 90% to 100%, you just used up a battery cycle. Even 99% to 100% counts as a cycle.
The method you described in your earlier post is for conditioning your battery, it works on older batteries but is not needed for lithium or poly lithimer batteries.
Tips for battery life, disable radios and keep screen dim. A dark wallpaper helps too, white screens are a battery drainer!

Get a app that disables other apps that start up on system boot-up or other events. Autostarts its a good app I use. As you all should know dont use app-killers unless u know how and when to use them (READ). Like said keep ur screen dim or on auto if u have that issue like me were ur constantly going in n out at work and find ur phone too dim for daylight. The darker your themes the better battery life. Remember that ur screen is one of the top (if not the top) battery drainers. Data, wifi, gps, bluetooth, auto-sync, running widgets, live wallpapers...if you dont need it on or could live without it, then either turn it off or get rid of it.
Also like said before, lithium-ion batteries dont suffer from memory effect like older rechargable batteries. If you could avoid it, dont run ur battery all the way down. Be free to charge ur battery as often as possible and that way you extend the life of ur battery.

Use the lowested sync frequency setting you can or manally sync. Wifi tether guzzles juice. Live wallpaper is a killer. Make task killing a subconscious reflex. The smaller the number is next to "running in background" also makes for more time away from an outlet. Of course these may not help any one else, but it works for me

I run the ParanoidAndroid 2.51 rom (10/24) with the KKO kernel and it goes pretty good so far. It may be the first day of using it but I will expectedly average 20hours of use on it. (using the live wallpaper phase beam the whole time). Used the wheatly governor with SIO and changed the max cpu to about 1028 so its only using 1Ghz. (seem to get decent battery life)
