We I am rooted and have tried several different 2.2 roms and kernals with no luck on battery life I can get 16-18 hours out of a charge with minimal use. Does anyone have any suggestions what i can do. Is there a go to rom and kernal? with all of the 2.1 roms i would get a couple days out of a charge. All i really want is to go at least a day without recharging, it sucks when im out and my phone is flashing red around midnight and ive barely used the phone all day.?!
16-18 hours? Jesus, I'm getting maybe 8-10. You should feel lucky.
check out Ava V9 + Netarchy's aggressive undervolting kernel. I swear thats the best combo ever. Battery life gets better daily with it, right now, its "meh" but it feels like its improving. First time i flashed it, my phone wasnt sleeping and it was dying while the screen was off, but wasnt losing any power with the screen on. So i let it die, charged it up to full, now it hardly loses power with screen on and off.
I'm only on my second day with it though, but its pretty amazing. And during the weekdays i use my phone heavy. Constant texting + music + twitter (3min refresh) + autosync + angry birds + wordfeud + space physics + browsing. I use my phone instead of my laptop, so thats why i have all of that going on, so from 6am till noon, i only have the screen off probably for a total of 30 minutes, everything i listed above is being used and it makes it to 60% battery left. As soon as my battery hits 20% it takes forever to drop, 10% takes even longer.
tl;dr Ava v9 + netarchy universal aggressive undervolting is the bees knees. try it out, not promising the same results taht i've gotten, but its always worth a shot
Edit: Also OC'd to 1.22GHz

Yeah but how much do u use it, on an average day i might send 20 texts and talk on the phone for 20 minutes and check fantasy football for a few minutes, if i even try to play games its like each minute of usage correlates to a 1% off my battery, gps off bluetooth off no 4g occasional wifi here and there and i even turn off mobile network which helps but i just feel like the amount i use the phone it should last longer

Since my last post I've tried my best to mimic your usage (i went way overboard on the texting, but thats good in this case). For the game, i chose to play Angry Birds for about 30 minutes. I also played a sht ton of WordFeud, since I cant go a day without dumping a lot of my time into that game. I browsed around on my browser and even downloaded some crap. Had WiFi and 3g on for most of the time.
So far im at 47%. I started at about 2pm and it's 2am now. Im going to sleep at 2am right now so there will be that idle time.
Edit: Just now woke up and I'm at 42%. Battery Indicator indicates that my phone has been on for 19 hours so far. Ava V9 + Netarchy's universal kernel may be the set up for you.
well ive had it on for only an hour so far so good... thank you for your time

No problem right now im at 5%...24 hours unplugged and 12 hours of wake time. Im beginning to think this is the best sense rom/kernel combo.

I don't really know what the problem is :/
Can you not find a charger within 16-18 hours?
Don't sweat the small stuff.
16 hours is good, why not just plug it in when you're sleeping?
I can go a good 24-36 hours on a charge and I'm using the phone 100% original.

I charge it all the time, before i leave work, when i sleep, in the car if i have to, it just sucks the few times i dont get a chance to charge the phone and im out with friends and i cant even use the phone because its like once the screen is on its time for rapid battery drain. Last night i lost 15% in a 7 hour span of not using the phone once. I even have set cpu set to the lowest setting when the screen is off?

Thats what was happening to me at first. With the screen off I lost all the power but with it on, it was all good. Confused me, so i went into recovery and just wiped cache and dalvik...dont think it did much, but i just let the phone die. The next day, it seemed better, the day after that, a lot better. There are some kernels where you barely lose anything while the phone is sleeping...but with this one, its like the opposite for some reason. Which is kind of a good thing and a bad thing at the same time.
I use Ava. I have a battery thread in the general forum.
As I posted in another thread:
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.

I am rooted, S-OFF, using the Sense Modaco ROM. Battery usage was no better with the Stock Bell Rom before rooting or S-OFF.
My main concern is the screen flickering at low brightness. it's as if it's unable to decide on a specific level of brightness and makes me question if it's actually saving any power.
I set my phone to Auto brightness and I am going to see if that is actually worse of if it's on par with 20%.
Ugh - just realized there is another thread pretty much all about this. I thought it was a different issue. Still, does anyone know if there is a better batch of phones or something? I have a FutureShop warranty so it'd be easy enough for me to replace if it will actually provide a solution
No-one has posted anything, to my knowledge, about a different batch of phones having better battery life. I would check out the other threads about battery life (including those on the G2 side too) and see if you can get yours to last better. But it could just be something faulty on your phone/battery.
Auto-brightness would make it even worse..because there is some type of bug or something that isn't making it function like it should. I was also getting terrible battery life until I followed some of these steps: http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
Biggest killers are any widgets that are constantly updating..or facebook/twitter apps that are constantly updating. As well..i recommend SetCPU to underclock your phone when your screen is turned off. This should also help with conserving battery life along with some of the steps provided in that link.

I am considering waiting a month or so and then having mine replaced. Unless I managed to figure something else out. My HTC Legend had better battery life.

The reason I want to try auto or higher brightness is to see if lowering it was actually saving me any battery life. I am curious if there's a driver or display issues that causes it to use the same amount regardless of the setting. So far I don't seem to be running out any faster @ auto than I was at 20%, but it hasn't been a long enough time to tell for sure.
Also I am unable to do the battery tip for the evo because once I turn off the phone and go to charge it again, it's instantly green. But I am going to try it anyway even though it's green.
Since writing the first post I used the OC module to get my phone to 1.2ghz. I have SetCPU set to run on boot with the onDemand setting. I have a profile that says to slow the CPU when the screen is off. From what I've read it doesn't make a ton of difference with this particular phone, but we'll see...

Yep, that's what I found too, when you try and charge it thinks it's already charged and goes green straight away again. But as you said, worth a try.
I just wanted to report back and say that I had my phone replaced. So far so good:
- No screen flicker issue at low brightness
- Battery has lasted nearly 20 hours with moderate-heavy use (played NFS Shift, setup basically everything on the phone after rooting, installed all my apps, backups, flashed some roms, 20+ texts, 3-4 short calls, showing people random apps.)
If it's not all in my head then this is definitely much better now!
Curious. It seems that everyone who reports the screen flickering problem has poor battery life.
Defective displays?
I feel my battery life is pretty bad as well. I've unplugged the phone this morning at 7 AM. Now it's 2 PM, and I'm at 37%. In between, the only things I've done are: send/receive a few emails and chat on gtalk. Brightness is at 40%, animations are turned off, wifi and gps location off. Using latest Cyanogenmod (6.1.1) and have no screen flicker issues
Edit: 17 minutes later, it's now at 27%
How long have you had the phone for?
Initially the first few days I got the phone, battery life was really bad, could drain in a few hours.
After a week or two of use, I now have reasonable battery life, the phone can last all day with light usage and still have lots of juice left. Actually I think if you make a few calls and a few txts, battery could last 2 days. If you play with it, one day for sure but you need to plug in over night.
(if you're talking to me) It's quite new, just picked it up on Friday actually. Also I've kept on researching, and it seems that poor coverage (like I have at work, from 7 til 3) tends to drain the battery even more, since the phone keeps switching between HSPA, 3G, etc.
I had my first one for about a month at least. This replacement was from Saturday.
Today I've had my phone unplugged since 8am, it's 5:30pm and I have 45% battery left, but the screen is the #2 user. Standby is #1 @ 40% of my battery usage, due to over 4 hours of time without a signal. The screen is only 24% and has been on for 48 minutes. Voice calls is #3 at 23% battery usage, with 23mins of calling.
My other phone would have died by now.
Also I spent an hour of streaming bluetooth audio to my car. Bluetooth doesn't even register on the battery usage. I've never seen it use more than 2% and it's always on. I am not sure why people say it uses a lot.
Just want to share my experience.
I too had poor battery life. Stock Bell ROM. Got to 3:00 pm and it used to die. Use this for work. Pushing data all day from Exchange server, bluetooth on all day because I'm in and out of the car, talk on average 30 minutes per day, texting, surfing, tethering, blah blah. Believe it or not, my old Omnia II would get me thru the day no problem.
I was also tempted to return it. But I decided to try a few things. Installed Set CPU and a task killer at the same time. Shut down as many tasks as possible on start up. Widgets and accounts, except Exchange-push, run and sync every hour. I get about 40% battery by dinner. I am happy now .
I'm quite happy with my Desire Z's battery life, It lasts for about 36 hours with moderate use. I have Juicedefender and Ultimatejuice installed, data or wifi are opened only when an app needs data connection, this increased my battery life by 10 hours or sth like that. Nice app.
I had terrible battery life until I went overseas. It is a stock Bell ROM, but I arrived in Spain Monday and am using a Spanish SIM card.
My battery life has increased from 14 hours with Bell's 3G signal to my current 27 hours and 35% remaining battery using GSM and WiFi always on. Funny thing is that no matter where I am it says the screen is by far my biggest power drain.
Where did you buy your Desire Z and how did you get it replaced? I'm with Bell and they would take mine to send out for "repair" but not sure if that will do anything. This will take 3-6 weeks apparently and I'm not sure if they it is worth it.
I'm running 10 hours with that I consider fair usage (few calls, text, map/gsp, and facebook.) My display is the highest battery usage at 60% and on for about 1:45h. I'm very disappointed.
Hey,
it's the same with my G2.
Max 24h.
I've standard ROM installed.
No WiFi.
Brightness to about 30%.
Juice Defender is installed and I'm surfing and just the regular stuff, but even if it's just in standby, it's taking a lot of power (display takes most)
Best!

I bought mine at FutureShop since I didn't think Bell would let me without buying at least a month of service (or being an existing customer). I also purchased FutureShop's extended warranty which is how I was able to get it swapped for a new one so quickly.
I use the extended battery for the evo. Lasts about 1.5 days with ass loads of use. Just have to trim the plastic edges a bit.

I have a couple of those red chichitech batteries but I wasn't able to notice any improvement with the problem phone.
My Desire Z also has a flickering screen at lowest brightness, and with moderate use it dies after about 12 hours max. Even on lowest brightness the screen ueses 59% battery. I rarely manage to make it through the day without having to charge the phone. Im on stock ROM with latest OTA (1.72) btw.
Gonna have it replaced next week just cause of the flickering screen. Has anyone tried the 1700mAH battery from seidio?
I am using Super Z Sense enhanced v3.1 with incredikernel installed. I've used my phone for around 10 minutes of browsing, and the rest of the time the screens been off. It's been unplugged for 3 hours 20 minutes. I unplugged it after fully charging it and now its at 68%. The display has been taking up 79% of the battery, even though the screens been off most of the time. What do I do?
lower the display?
and every ROM displays things differently. If your battery isn't affected don't sweat it. I personally haven't run that ROM so I can't help you there.
It is on miminum brightness, and my battery is greatly affected. Not using my phone I have maybe 12 hours of standby battery life.
I'm having the exact same problem..... backlight is turned off and my display is using 79% of the battery.... I'm in cyangenMod 6.1...
any ideas?

I've replicated the results with a brand new battery from Verizon (after several charges, the capacity should be fine now) and both CM7 (Build 45 from Gridlock) and Uber Z RC2 and several different kernels. I think this is just the design of the phone, or I got two defective batteries in a row
There's an important piece of information missing here... Is your Incredible's screen the SLCD type or AMOLED type? SLCD screens don't use any more power due to what's on the screen due to the type of backlight (same light illuminates the whole screen), whereas on an AMOLED display, each pixel is its own source of light. That's why on an AMOLED display, darker themes offer better battery life as the pixels aren't having to light up as much to display the content.
Might need that info.
I have a slcd display....

Another important question: 3G or wifi for most of the day?
I can get 6-8 hours out of a standard battery running on 3G with wifi disabled, but if I am on wifi I can get 18-20 hours...
I spend most of my time in 3g.... I'm in the nightly cm6 rom with #21 kernel now and I'm getting the 20 hours I was hoping for.... life is good.

I had the same things running Z ROM's. I switched to Myn's Warm TwoPointTwo, and the display is low, right now 7%, and same usage patterns. 3G all day at work (8 - 5), Wi-Fi all night until morning.
Maybe a phone call a day, maybe...emails/TweetDeck/texts/web browsing otherwise. It seems that that's the way Z ROM's on this phone run...?
I too have this problem on any aosp rom ive ran on it whether it be gingerbread or froyo. The display will take up a good 80 percent battery life, making my Seidio 3500mAh battery able to barely able to get through the day. However, on a sense rom the display takes maybe 5 to 7 percent and the battery will last 3 or 4 days. I was wondering if anybody managed to figure out a solution to this, as I want to run gingerbread but can't due to the battery issue.
My incredible is of the slcd type. Any solutions worth trying?
having the same issue with CM7 nightly builds... display using over 70% all the time... terrible battery life. otherwise CM7 seems very stable, thanks to all those involved in making it happen, you guys rock!
any help with the battery/display issue? thanks
Don't forget, these are percentages. Each rom/kernel combo calculates the percentages differently. Your may be getting actual better life, but the meter says 70% of the total usage because the Android System and other services aren't using nearly as much battery vs a stock kernel/stock rom.
The problem we have here though is that the battery life is greatly affected. Stock battery gets maybe 12 hours standby on a fresh install and screen mostly off. My Seidio 3500 barely makes it through a full day on any aosp rom yet lasts 4 days on a sense rom.
Sent from my ADR6300 using XDA App
Sync
Another couple players in battery life besides display are frequency and quantity of accounts synched, as well as GPS on/off.
Not magic bullets to battery savings since Display is the resource hog in this instance, but you may (should) be able to squeeze several additional percentage points out of the battery by tweaking the synch quantity & frequency, as well as toggling GPS to off unless it's needed.
Mindblowing if the 3500 doesn't last a day on a full charge.
Absent that, I've read varying opinions on whether the xx.9 radio is a battery eater.
I figured out my solution. Update your radio. 2.15.00.07.28 doesn't like aosp roms, so I upgraded to 2.15.00.11.19. MUCH better on the battery life (doesn't run my Seidio 3500 dead in just one day, more like 3 now) although as a previous poster suggested, the percentages in the battery life display are just that. Percentages. The display still shows ~50% of the use, however the life has returned to normal.
Link to radio images: http://forum.cyanogenmod.com/files/category/25-htc-incredible/
And I know some of you are wondering "How in the f&$* can the radio affect the displays power usage?" To be honest, I don't know the answer to that either. I just tried this on a hunch and it seemed to work. Full day of not exactly light use (browsing while wifi tethering, some bright sun use as a navigation device, texting all day) and no forced attempts to be frugal with power (letting the screen time out on its own instead of immediately poking the power button, accidentally left wifi on most of the day, automatic brightness with a lot of full sun use...) and I'm still over 60% after 14 hours. Your mileage may vary.
I have to charge it twice a day, and my use is for only couple of hours talking and few browsing.
I tried that with stock as well as
[ROM] cwm-Phantom-X-
is anyone else also experiencing the same?
a few hours being like 10 hours straight talking?
You're crazy. This battery is the best I've seen in a long time.

I can drain a battery in 6 hours or less. I can't make it through a 8 hour work day without charging it. I guess you guys that go 12+ hours on a charge aren't power users. I tried every rom and kernel and my results are exactly the same.
Maybe the people who are complaining about battery life came from a flip phone or a blackberry. As far as smartphones go, this is the best you'll find for the features and enormous screen we have. Don't believe me then get an Amaze, Sensation, myTouch 4g Slide or G2x.

I dont know bout anyone else... but the only battery problems ive experienced is the fact that ive become so damn lazy on keeping the phone charged.
The battery lasts so long that i forget to charge it, and then i run out of battery
I'm a heavy user literally all I do is watch 1080p movies and plays games on my phone. I get twelve to fourteen hours every day. I also get at least a text every fifteen minutes if not more. Maybe the developers didn't remove career ciq which bogs down performance and drain the battery. You can also try a different kernel.

don't forget that in areas where you have crappy signal, you phone pumps up the power to try and compensate. you may notice your phone heating up in your pocket too. If you have no signal at all, i weep for your battery life.
go into airplane mode to save juice.
I too get 24 hours or more from light to moderate use with juggernaut.
Heavy use still nets me at least 10 hours. Although I toggle things off if I remember and don't need them. Like wifi, data, auto bright, sync, etc. although WAY lead important with this phone than it was with vibrant running cm7.

Why don't you try adding another core to your G2 and see if you can even get 6+ hours!!!
Cmon man, this is a dual core phone...it's just common sense that it will use twice as much battery power to get it to run smoothly.
But honestly, I was able to get 21hrs out of a full charge. With heavy use but i had it UC'd @ 1.2max and 192min. Still ran pretty smooth tho.
I get about 18 to 20 hours from a full charge. Stock. Non-rooted, and no modifications of any kind. I have all my apps auto-sync every 4 hours, and my usual display "on time" is around 4 to 5 hours. Here are some screen shots. This is the best battery life I ever had.
Just to add. My brightness is at 40%
is it better to use autobrightness on our device or a set brightness setting to save battery?

I'd say set it to certain level. Having the phone constantly adjust I would think would use more battery.
Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...
It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

Yeah, I know how you feel. Just experiment other ROMs and see if you get any changes.
How much usage would you get out of juggernaut?

Its been a while since ive run juggernaut. But it used to only drain 10% an hour i believe on 4g. I've restored my nandroid of Jugg and will be monitoring that.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost
Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.
I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.
Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).
Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.
The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

I second this. If battery problem persist download better battery stats to see if you dont have any kernel wakelocks
