I finally gave in and rooted my phone after researching it thoroughly. I used unrevoked to root and have flashed fresh 3.4.0.1 and netarchy 4.1.9.1 and am using set cpu, too. but my battery drain is just as bad before I rooted.
before the last OTA and before root, i could get a good 14 hours with moderate use and time without signal was lower, but now it seems my time without signal is rather high(i do get lousy coverage in my house, but outside its great), and i am sure that may be the main culprit of my battery drain. I am usually lucky to get 8 hours now.
My question is there an app that works reliably to prevent such a heavy drain because of the searching for a signal, without going straight to airplane mode. or is there something i may have missed rooting it and should check some settings? I was hoping to get it back up to 14-16 hours of battery life with rooting it.
I'm curious too and switching to wifi when wifi works helped my battery alot. But still my battery is like 12hrs then dead.

I havent seen an app that does this. I am curious though because unless you are in your home a significantly more amount now then you were pre root you still shouldnt see that big of a drop in battery time from signal.
how long ago since you last wiped data on the phone (probably last time you flashed)?
did you recalibrate your battery after flashing?
did you reset up all your settings to optimize battery?
are you using the HAVS version of Netarchy's kernel?
i know lots of questions but these would greatly help on what you have already tried and what you can still try.
I am also running Fresh 3.4.0.1 at the moment testing it out and i have gotten the best battery life out of it using the No HAVS netarchy kernel and the collins battery tweak set up WITH OUT setCPU. I also use the paid version of juice defender (ultimate juice) and have that set up to drop data connection while the screen is off. I am normally in the heavy user area but lately have been busy so have slipped down to the moderate level and i can still easily get all day (about 14 hours).
If you are a true heavy user i would expect 8-12 hours of battery life, mid user 12-16 and as a very light user your milage may very greatly. I am assuming since you previously fell into the 14-16 hours your a moderate user. if thats the case you should def be able to get back to that.
I did not recalibrate the battery. Is that done through the recovery menu? And should the battery be fully charged?
I am still learning about roofing and what I can do and should be doing.

Even after rooting and wiping battery stat again, it's still barely scraping 6-8 hours(with auto starts and juicer defender on)

I found this app on app brain, green power premium, (can't link since i am a new user on xda) and tried it out last nigt on a full charge before i left for work, about 13 hours later i just got the warning to plug in my phone.
basically it manages your wireless networks within your parameters you can set instead of manually turning off networks, etc...and that was one of my main issues of battery drain.
Calibrating your battery should help out.

11 hours of moderate to light use (about 3.5 hrs of awake time) and the battery has 64% left.
so I flashed from fresh 3.4.0.1 to myn's warm TwopointTwo (RLS3)
and went from netarchy 4.1.9.1 cfs havs kernal to Kings #11 with havs and cfs.
I am using setcpu (all on demand profiles): screen off 384 max/245 min, battery <50% 614/245, temp >40.8C 614/128, and Charging/Full with 998/384
and the other app I am using is called Green Power (i am using the paid premium version) my settings on it are Managing Mobile Network Only. Keep wireless on if power is on, Keep wireless on if screen is on, Check traffic before shutting wireless off and start up at boot, Durations ON 1 min - OFF 10 min.
I am rather happy with this setup so far, and really digging myn's rom. i loved FRESH, but mostly because i spent months just using stock sense and got so use to it, switching to FRESH when I rooted felt natural.
I've read on many reviews (Gizmodo, Engadget, CNet, etc) that the battery on the DInc is not that great, but mine is incredibly... bad. Examples:
I browse the web (mostly mobile websites with not many images, flash etc) for ~20 mins and battery life decreases by 20%
I leave the phone ON overnight without charging and it's at 2% in the morning. When I went to sleep it was at 60%
I turn the phone OFF overnight without charging and it dies (I couldn't turn it on, had to charge for 15 mins even to turn on). When I went to sleep it was at 30%
I've also heard both that ATK is useless and that it's a gift from God for battery life. I'm running the Pro version killing every 30min and it's not helping that much (maybe 30 mins)
Is my battery defective, or are other users also experiencing this bad of battery life? My DInc is SLCD, running UberZ RC1.2 with stock battery.
Im guessing you havent had your incredible for more than five months right? Considering htc didnt start making them until the late summer. Anyways I do know that desire z ports often use up quite a bit of battery in their displays. However considering you left it on overnight and it was nearly dead I dont think it was that. Something you can try is going in the advanced menu on clockwork mod and erasing battery stats. This seems more like a defective battery though. New batteries can be bought for fairly cheap and if you do decide to get a new one you can get them for pretty cheap. Touchpro 2 batteries supposedly work with the incredible as well
Make sure you turn off GPS, WiFi, Bluetooth, etc. when not in use.

Yeah, I've had it for about a month. I will reply after erasing battery stats and trying it out. I'm not sure that I would use a Touch Pro 2 battery - seems like too much of a risk. However, I have seen Evo Batteries on Amazon that supposedly work with the Dinc. Do they?
If it helps, I use widget locker, with: extended controls, fancy widget, nexus revamped (with a lot of spawns on slow) and 3 sliders.

I have, I barely use BT or GPS so they're almost always off. I only turn GPS on when I'm charging and I'm using location based apps. 3G is off at home and Wifi is off on the road / at school and when I'm not using the phone.
What you might want to try doing is uninstalling widget locker and charging your phone all the way up. If after uninstalling widget locker the drain is still significant it may be the battery. And from what I read, the evo battery works with the incredible, it just makes the back cover fit a bit more tight.

OK, I've wiped battery stats, though it's only been a few mins so I can't tell yet. I'll reply in a couple of days. Also, can I just disable WidgetLocker instead of uninstalling it?
I also have a silicone case that hooks on the front edges, will an Evo Innocell (with back cover) mess with that?
I dont think an evo back cover would work for the incredible as they are not the same dimensions.
And btw touchpro 2 battery will work with the incredible

Heres one for $5 if youre thinking about it.

I just moved to an Incredible from my Droid 1 and the battery life is horrible compared... I got it as a replacement for having so many issues with my Droid but the battery life is almost unusable I'm running CM 6.1 and I wiped my battery stats, drained the battery then let it charge overnight powered off and I still get really bad life... I think a lot of it may have to do with the stock 1300mAh battery compared to the Droid having 1500mAh but I'm not sure... I'm considering the 3500mAh sedio battery but $70 bucks is a bit steep atm

Thanks for the great find, though I was thinking about maybe one of those seidio 3500's. Though since it's so cheap, I'll probably buy it

I've seen one on amazon for ~$25. Not seidio though. Reviews were meh.
I don't think its the 1300 mah vs 1500 mah. That's less than 20% (so like 10 hrs vs 12 hrs).

Don't run ATK. Android manages apps by itself. There's a whole lifehacker article on it.
Sounds like a run-away app.
Hmm, turn your screen off and let your phone sit for 5 mintues. Go into Settings > About Phone > Battery > Compare uptime vs awake. They should be AT LEAST 5 minutes apart.
If they're not, go to the market and install "Watchdog Task Manager" (<--this is NOT the same as ATK, again, lifehacker article on it) to monitor rouge apps.
Hope this helps!

My phone has been sitting and charging for ~2 hours, but up - awake = 5:12. Is it normal?
Great work, by the way.
There is no normal.
Up time is the elapsed time since you turned your phone on. (i.e. after the phone was completely off, not just screen off/sleep mode).
Awake time is suppose to only be the time your phone was actively being used (i.e. screen on).
So, Up time minus Awake time should equal the time your screen has been off, (i.e. asleep).
If Up time and Awake time are equal, and you've had the screen turned off (i.e. asleep) for part of that time, then you have some app that's staying active durning sleep mode.

I might reboot when I go to sleep tonight and do nothing on the phone, then check uptime vs awake when I wake up.
1300 Mah battery is not acceptable for a phone of this caliber. There are alternative options for battery's. I use setcpu to underclock the proc and I've seen a dramatic increase in battery life.

I've been using Setcpu as well, with 998 mhz while charging, 245 when screen off, 245-520 when hot or <20%, and 245-850 otherwise.
Agreed about the battery, HTC and VW probably want to force you to spend more on extended batteries.
Too bad, otherwise it'd be a perfect phone.
HTC usually seems to skimp on the battery. It really hurts their reviews but I suppose they can save costs and assume people can always buy an aftermarket battery. I don't agree with it but it's their business.
Anyway, that does sound like abnormally bad battery life, but I have a question - are you in a poor service area? If so, the radio might be working extra hard to acquire a signal. Even when I had my dumb phone Samsung alias (which had decent dumbphone battery life) I would experience complete battery drain if I left it in my poor coverage basement overnight.
Also, when you're browsing the web and such do you use wifi or 3g? I notice that when I continuously surf with 3g the phone starts to get warm, especially in mid-poor coverage areas. When the phone gets hot the battery gets hot, and when the battery gets hot it drains much much quicker. Of course, high power usage generates more heat so I'm inclined to believe our 3g radio consumes way more battery than our wifi radio.
Over the months I've combatted poor battery life by doing the following:
1. Purchase aftermarket batteries. I've fallen into HTC's trap. I bought an evo battery which can last me of 6-7 hours of wifi awake time and 4-5 hours of 3g awake time. I also purchased the extended 2150 battery from Verizon which I can get up to 10 hours of wifi surfing and 5-6 hours of 3g surfing. Back when I was on stock 1300 I would get 3-4 hours wifi surfing and 2-3 hours 3g surfing.
2. Install an undervolted kernel, if you're into that sorta thing. One of the main reasons I'm able to obtain the numbers above is due to my kernel which undervolts the processor. I use adrynalyne's experimental undervolted kernel and it works without a hitch. I use it in conjunction with setcpu so I can have a screen off profile which underclocks the processor to 128-384MHz while I'm not using it. The only caveat to using this kernel is you can only use the conservative CPU governor. This means lower clocked speeds will be preferred as the CPU actively scales itself, and will take longer to ramp up to the higher speeds. But we're talking about maximizing battery life so that isn't necessarily a bad thing.
3. Try to keep screen brightness down, minimize usage of other radios (Bluetooth, GPS). Sounds like you already do this though. Rogue apps have also been discussed but if awake time != uptime then that's usually not the case.
As also prevoiously mentioned, it is possible you have a defective battery and should go about getting a new one from them though I'm not sure how that process goes... someone here is bound to know though.

I definitely stand behind adrynalyne's experimental undervolted. You can find a link in the kernel thread on the android development section of this board. He makes a sense and AOSP version. I've tried some of the newer ones like Chad's but I love the longevity and stability of adrynalyne's too much to live with the switch. As aforementioned, if you decide to use setcpu, make sure to only use the conservative governer. Ondemand will cause it to freeze! Otherwise it's rock solid.

Last straw was last night. Had 13% battery life left before softball last night and knowing I wouldn't use my phone during the games, but having been burned by my battery before, I shut my phone down before the games. Played softball for two hours then turned my phone on. Booted up long enough to see that I had 0% battery before it shut down again.
What am I doing that's causing this? I get maybe 10 hours out of a Seido 1750mAh battery. I have no apps that do background updates. I keep my display on "dim" most of the day. I go most days without even making or receiving a single phone call!
Ideas? Thanks for any help. This is really frustrating.

Seido 1750 mAh battery
I'm not sure, but there have been claims that Seidio inflates their numbers and their 1750 mah battery isn't actually that much. Has this been something that has been happening gradually? Like your battery life is degrading over time and now it's at an unbearable point?
Try a different Kernel or Baseband. I'm using MIUI w/ incredikernel and get great battery life w/ stock battery. I'm also using 2.15.00.07.28 Baseband. I use SetCPU to set a screen off profile of 245min 245max, havn't noticed any lag while having that set. If you wish to update your radio easily you could download "Inc Bits" from the market. Great app has all of our phone radios, all you need to do is rename it and move to SDcard.
Agree with tcberg2010 here. Try incredikernal with Smartass governor. Check out vipermod. I was having intense battery issues which i posted about a week back. My suggestion would be to get spare parts app and check partial wakelock to see if anything is keeping your phone up. I use maps occasionally and it turns out that it was causing partial wakelock constantly. After disabling a locations and gps i am back to standard battery life. Looking forward to next cyanogenmod update, hope there is a fix...
If your phone died while it was turned off, then I would either have battery tested or get another one it could have an internal problem.
Yeah unless the phone some how got turned on in your pocket (I'm not sure how, but it has happened to me), There should be minute if not no drain on the bat at all. I'm not sure where you can get it tested, but I would certainly be wary about that bat. Do you still have the stock 1300? I'd check to see if it looses charge while the phone is off. Maybe there's a short in the phone.
Thanks for all the suggestions. I'm at about 10.5 hours right now and 7% left with the only thing I've changed being the battery. I went back to my stock battery. Going to try a new radio first, then vipermod.
try the "battery moniter widget" from the market. it keeps perfect tabs on your battery, can tell you the REAL mA of your battery, temp, usage stats, all kinds of stuff. it's really a good app to use to watch your battery...you could also use MIUI, and watch your battery life almost double. it's superior to CM7 in so many ways. and the people that have used both, i think pretty much agree...
I have a year old EVO and love it. But lately the battery life f'in sucks. Just today I was using it at work, the battery was at 70% then the device shut off. I rebooted to find the battery at 0%???
I have been on Synergy Rom (Non God Mode) and Freedom Aggressive for months, but it seems the battery is just getting worse and worse. Could it be as simple as a bad battery? Or should I try a less aggressive kernel?
bummed about my phone, and not ready to upgrade just yet... have to wait till may ..
So I just hooked up to the computer to charge and reboot, now it shows at 83%. WTF???
Thanks for any input or advice in advance...
Try undervolting your kernel using viperMOD, or try this trick by zeppelinrox: Calibrating Without Downtime!
Get the F out of here?
Im running into the same issue. Phone is almost a year old, running Mik 2.59 with the agressive freedom. WTF is going on? Im going to try the links above and see what that does. For real though, same thing, charged at 80% then phone shuts off turn back on its at zero, then plug it in to charge and it's at 55%. crazy!!!! Hopefully the tips will help. thanks
edit: The calibrating without downtime wont work. When you pull the battery the phone won't boot at all. This must be a motorolla thing where the phone will still boot without the battery. Didnt try the vipermod tip yet.
I'm experiencing a similar issue - I'll pull it off the charger at 100%, check a few emails on my way to work and i'm suddenly sitting at 70%...sits on my desk with an occasional email check and by lunch I'm at 25%...I can play a few hands of solitaire and watch my battery drop by 10% in less than 5 minutes...or surf the net and see it dropping a % a minute or more ... even sitting in a full 5 bar svc area.
I'm starting to wonder if my choice of Synergy RLS1 with the Freedom (Universal) kernal is the cause.

This is what I came up with after thinking my ROM was messing my phone up. Check it out. Since my phone was almost one year old, I figured I should check to see if battery was good anymore. I went to Sprint to check it and sure enough the battery was bad. Changed it out and now my battery life is back to normal, even better with the ROM and

Try this....it worked for me a little while ago when i had batt issues....charge your phone to full while its on... Then turn the device off and unplug the charger ....wait till the led turns off then plug it back in...wait until it charges to full and them repeat. Unplug...wait for led to go away and charge again...after a few times repeating this process boot into recovery and wipe the battery stats and reboot and unplug from charger...did that and i got a 16 hour batt with moderate usage and no extended battery... Hope this helps

I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.
Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom
Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/
You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.
Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/
Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

I had an Evo, loved it,but the battery was trash,even when I bought my 3500 mah battery, the juice in it wouldn't last a whole day,sorry man,there's just no hope for that phone,without undervolting properly

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.
