Best rom/kernel battery life combos for hw:0003?

I am using ava z3 and caulkins modded(uv and sdfix) HTC 15 kernel.
I only get about 11-12 hours of battery life with moderate to light usage (20 mins of phone, 25 or so texts and maybe 25 minutes of total web browsing)
I see all these posts of people having battery life lasting 20+ hours...
I have setcpu drop my clock when screen is off, random advanced task killer taps, autosync off, gps off, Bluetooth off, and only use 3g all day. Anyone have any combos that I could try or possibly some tips to get my bat life higher?

No clue, MIUI doesn't give the awake vs. uptime like a sense rom does. It was with moderate use, maybe 30-40 texts, a bit of browsing, maybe 30 minutes of mini squadron and a few short phone calls.

Myn's Warm 2.2 RLS5 with netarchy-4.3.2-cfs-nosbc-havs-more has done wonders for my evo. I use SetCPU and set the govenor to smartass, have one profile for screen off (384max, 128min smartass). I can get about 7 hours of uptime(20 hours of total up time= that averages to 21 minutes of use every hour...) with 1.5 hours of that being phone calls, about 50 texts a day, checking 3 e-mail accounts (gmail's push) and reading my hundreds of RSS feeds with NewsRob.
The only other time i got similar results was with Warm 2.2 RLS4, HTC kernel #17, and some very aggressive SetCPU profiles. and similar usage.

well if you look at the power usage you can click display and it'll show how long your display was on.
what brightness do you set yours at and do you use a stock battery

i have a 003 evo and i find myns rls4 & netarchy 4.2.2 less havs/no sbc the best in battery life & speed.

where do u check this 003 thing? and i have miui 1/21 zendroid kernel about 15 hours so far at 72% wifi on all day 50-60 texts and probably an hour of fb hahaha

To check what hardware go to settings-about phone-hardware info
Also, is anyone using aftermarket batteries or stock batteries for these impressive battery lives?

im feeling pretty stupid right now haha i cant see it. Im running miui rom and i go to about phone>more info but i dont see it

Ahh in ava z3 its similar to stock where settings-about phone has software/hardware infos... I wish I could tell you how to find out because I have been getting the feeling the way hardware reacts to Rom and kernels is a big deal. My buddy has hw:004 running same Rom and kernel and gets about double the battery life

Ok so ive been changing different kernels just to see if i can get different results. Now im using KingKlicks #12 w/ myns rls5. I use my phone alot & am just looking for SOMETHING that will help my battery life.
So the other day i was in this super retardly long useless meeting. Less than 10 texts, no internet, no apps no nothing. 4g, GPS, Wifi & bluetooth all off. Granted that isnt my regular useage (I really use my phone) but this is the best battery life i could get. (SetCpu on w/ a helluva lotta profiles)

3 days??? wait wait...either thats photoshop or you've got a different phone than me!!! In any event im flashing netarchy as soon as i finish typing this!!!
Do you use your phone? Like heavy useage? Or is that 3 days with absolute minamal useage?? 4g, wifi, gps & everything else off??

The question is, what is the definition of best battery life... How long the battery will last with the phone doing nothing? If so, I can get a good 4-5 days using the setup in my sig with just a minimum of texts, calls, and emails, while on wifi.
However, actual practical usage, including 3g, 4g, web, text, calls, etc. Results in a good 1-2 days of battery life. I think once a user has all the bugs (rogue apps that are causing wakelock issues) worked out, that user should focus on optimizing the system for best results for the way THEY use THEIR phone, not the way someone else uses theirs.

^^Agreed i am trying to find the best fit for the way "I" use it however suggestions are welcome. BTW you get 4-5 days 'cause you've got the extended batt. I wanna squeeze every last drop of juice out of my stock battery!! If you can help me there then by all means...please do!!!
Edit: side bar i just flashed netarchy's 4.3.2 cfs-nosbc-havs-more-universal and everythings fine but when i plug my charger in AC or USB it throws my phone into a boot loop....Any ideas?? Btw yes i am gonna find the netarchy thread and ask in there as well.

What's the best one for Myns Rls 5 ?

What's the best way to find the wake lock issues, are you referring to maps, voice, or other random apps running in the background? If so what is the best way to keep these apps but put an end to the wakelock issue.
I am still running ava z3 but I flashed the netarchy 4.3.2 cfs-nosbc-havs-more this morning, downgraded my pri and nv because netarchy said to for battery issues, gave it a full charge from 0, and my battery was garbage... 5-6 hours with a moderate use. Calks modded htc 15 w/ uv and sdfix worked way better, but still can't find these magic 20 hour battery lives that I am dying for.
Reflashed the new pri, nv, and Calks modded 15 and my hunt continues, about to give myns a whirl despite liking ava z3 a lot.
How simple is myns, bloatware gone, fairly simplistic, pretty snappy and lag free? Difference between rl 4 and rl 5?

Use the battery history function in Spareparts to see what's causing wakelock. As for ways of dealing with it, that's up to the developer.
I don't have too many apps on my phone, just the necessities. Of the main apps I use, k9 and handcent both had issues.
With k9, any time I'd receive an email (using imap), the phone would stay wake locked for 60 seconds. This may not seem like a lot, but after getting many messages throughout the day, that could add up to an hour or more. I experienced this both with fresh 3.5.0.1 and evio2 1.75. When Evio2 1.7.7 came out, I was hesitant to switch - I'm not one that flashes roms every other day just for the hell of it. I already had the phone set up and configured. Decided to give it one more shot, I installed 1.7.7 from scratch and started reinstalling apps.
Through out the process, I was very careful to monitor wakelock state. For what ever reason, k9 was no longer causing wake lock. Something in 1.7.7 changed. It wasn't kernel related because I've tried way too many kernels with similar results. So now, the only wake lock is when the program actually receives an email. Usually 1-3 seconds per email received.
Now with handcent, there is a known issue if the popup function is enabled. Anytime a text is received, with popups enabled, the phone enters a wakelock state until that text is acknowledged. This occurs even if the only popup task is to display the text, and NOT turn the screen on, or flash the led. The fix? Disable popups in handcent. I've posted on their forums, but haven't gotten any acknowledgment. I'll continue to use the program, but without this functionality.
For other programs, best bet it to try to narrow down the conditions causing wakelock and either work around them, or work with the author to try to resolve.
Any as for stand by time, I'm sure even with a standard battery, 4 days is possible if the phone is idling the whole time with data turned off, and minimal or no other usage.
As for kernels, there are other factors at play besides the kernel itself. These include the governor in use and its parameters. Two otherwise identical phones with the same kernel and governors, but different governor parameters will result in different battery life.
In the end, I chose to stick with the conservative governor.
These are the governor parameters I changed in the init.d folder
Filename: 01cpufreq_screenstate_scaling
Code:
MAX_CPU_SPEED_VDD="921600"
MIN_CPU_SPEED_VDD="245000"
#MIN_CPU_SPEED_VDD="384000" DEFAULT
#MAX_CPU_SPEED_VDD="921600" DEFAULT
CONSERVATIVE_SAMPLING_RATE="50000"
CONSERVATIVE_UP_THRESHOLD="80"
CONSERVATIVE_DOWN_THRESHOLD="55"
CONSERVATIVE_FREQ_STEP="10"
#CONSERVATIVE_UP_THRESHOLD="65" DEFAULT
#CONSERVATIVE_DOWN_THRESHOLD="35" DEFAULT
#CONSERVATIVE_FREQ_STEP="15" DEFAULT
These settings were not arrived at trivially, but were changed slightly one at a time, then tested by using the phone. I was looking for decent response/user experience. I was also trying to get the phone to utilize a larger range of cpu speeds than originally programmed into the ROM/kernel. Google the different parameters to understand what they're referring to.
Edit: I'm also using the -100mV undervolt script as opposed to -50mV that the rom originally comes with.

Battery love (life) on VillainRom 1.4.0

So i'll cut to the chase, Battery has been ok with stock rom, after freezing the **** out of some apps, BUT, with VillainRom the phone is working perfect + battery life is amazing.
What is amazing?
53 Hours and 30 minutes since full charge.
I did charge it in the car for very short periods while using GPS and screen on full brightness.
How was the phone configured?
- Wifi/3G Data on at all times
- Push GMAIL and What'sapp
- Screen Brightness on full and the "Adjust screen power" option ticket off.
- Lookout installed and running in background.
- Bluetooth always on, not always connected though.
- 3 Hours of display usage
- 1.5 Hours of calls
- Some gaming, browsing etc.
Don't believe me?
Here are screenshots!

Thats really good but i couldn't get anywhere near that, not even without using the phone. I average no more than 10 hours.
Well done mate i wish i could manage it myself.

Anyway still don't understand what's good about this battery stats ...

@sumeshd,
You know, I don't get money from Samsung or anyone else for posting this? Why would I lie? Anyway, believe what you what, I really don't care that much.
I'll just say again, brightness is @ FULL.
3 Hours, is not ONLY, that's my usage, and you don't have to like it or not.
@bilboa1,
If I wanted, I can charge the phone almost 24/7 I got a charger my car, at home, at work, and even a portable solar one.
The charging peaks you see are mainly USB file transfers for a few minutes, and the long ones are around 30 minutes while driving with GPS + Screen at full brightness.
So the consumption on those moments is rather high, which means the battery isn't charging all that much.
@Mittaa,
You take a 4.3" Smartphone that does everything, and get 53 hours out of it, it's not enough??
if the little charging peaks were not there i'd still get around 46 hours from the phone, is that not enough???
Anyway the information I posted was to help people who are trying to choose a ROM, chose this one, or other people who are having battery problems have a reference.

eitama dont bother posting let this thread die please .
Two reasons one you will find certain users insist you have poor gps yellow screen bad battery life etc . Not worth bothering with if you are happy with your phone .
Reason two is a bit selfish as posting VR great battery life means we are going to get hundreds of numptys posting in VR rom thread who wont read and cannot follow instructions .

Nice to hear that your happy with your phone ... i'm happy too
I also understand that this is way better than your old desire HD (same for me moving from my old HTC Touch HD)
But I can't understand what this have to do with "whatever Vanilla Rom" ...
Lots of people can get this kind of battery live using stock unmodified, non rooted SGS2!
It could be very usefull if someone made a exact compare between two SGS2 running different ROMs.
First same configuration (screen brightness, auto update, widgets etc) then full charge.
Then 15 min GPS (same route), 15 min browsing WIFI (same websites), 15 min gaming (same game), 15 min talking (same person (sorry bad joke)).
Al together 1 hour of heavy identical usage.
Finally screenshots of battery stats and post here on XDA so we all can clap our hands for the best bettery saving ROM of the week

Well I tried to drain the battery on vr playing games etc to calibrate, and struggled, like noonski did.
I could drain stock rom with ease, but can't do it nearly as easily on vr.
The general consensus from reliable members like nobnut and jje seems to concur with it being better

well as I said I have tried all the roms..
I have tried vr4..for many days..it gave me 9+ hrs..
good u r supporting vr but not good that u r filling threads with "anything"
this is my battery with batista70 rom..and I m happiest with it..
PS: note the screen wake time bfor commenting..(its awake most of the time bcoz my heavy txting and use)..
and I am on 3g/h network with data active all the time..
this is the best I could get till now(with my usage)
no hard feelings..

People seem to be getting time between charges that vary wildly, but for me the biggest indication of battery life is obviously 'display on' time, and this seems to be roughly the same for the vast majority. Best I've seen so far is 4 hours, and that was mainly 3G/HSPDA browsing. My most recent however was slightly over 2 hours with VR 1.4, and again that was mainly browsing with data.
So while a screenie showing over 2 days may look impressive, it's how much actual use the user got that's important. The post above that showed over 6 hours was certainly impressive, but how much 3G browsing was done? How many 3D games played? GPS? etc etc

<shamed> - sorry for long post!!!
@ OP - you had a few minutes under 3hrs of charging. That is in excess of a full charge of the battery! And a total screen of a a few hours.. Nothing impressive at all. Saying you had on GPS and screen on full brightness negates the charging is just silly. It is usage, and usage is what we're interested in.
@ mittaa + Zedwings: Completely agree with both. Even display on (IMO the most accurate comparison) is a long way from the full truth for comparison in testing and a very fixed test environment would be needed to test a pattern of usage. I started to think about this like mitaa suggests (and when you do, you realise it is virtually impossible to co-ordinate without resetting back to factory) and there are still variables.
And anyway, it's kind of irrelevant at that point. You wouldn't consider doing it unless you're battery life is not meeting your hopes or needs. but your usage is your usage and you'll be happy or not.
Unless you are prepared to compromise on screen time, game playing, widgets, sync settings, live wallpaper etc, then what does it matter? You must find the balance between battery life and customisation that YOU can live with.
Personally, I do this by running my phone in 'full fat' mode. All radios on (this inc. GPS), synch on full, screen set to about 75% (no auto), the widgets I want, high spec live wallpaper (like Galaxies!) that make my £500 phone look like a £500 phone. I settle into my daily usage pattern, charging whenever I need to charge. This is why I bought my phone, not to immediately turn everything off and play the 'longest, littlest' game!
After about two weeks and this has settled into a fairly regular pattern, I start to switch off the things that mean least to me, one by one, day by day until after a numbers of days I find the balance that I can live with.
Personally I start with turning into perm 2G mode as I have wi-fi almost everywhere I go and I live in an area where 2G and 3G is on the cusp. This is extremely draining to batteries (I deal with none phone GSM equipment every day where battery life is key) and I know signal stregnth on the band you're using, constantly cylcing between band (and the variance in antenna power) is the single biggest thing to affect battery life asside from screen. It may not reflect this in stats, but trust me on this... If I lived and worked in a strong signal area, it would drop a few places down the list, extra call quality is nice as well as data.
For those of you living and working in London for example, but mostly out and away from Wi-fi, then consider leaving 3G on, and turning Wi-fi off.
Wi-fi scanning for networks constantly is another big drain.I have noticed this about Android, it allows you background apps to work leaner than the iPhone in power consumption when you have lots of widgets and synch etc. However the iPhone actually uses GSM to perform background tasks when the phone is off (shutting down wi-fi radio which reconnects as soon as you unlock the screen). This means that if you're out and away from a friendly hotspot all day, battery is less affected than an android.
Anyway, sorry for the long post, but hope you all have luck in finding your 'sweet spot' in usage / customisation.

Well, that's good. Recently I got a total of 16 hours including 57minutes screen on time.

3h screen time on is nothing, on 2-3 days it's called very light usage.

consistent problem with high "DISPLAY" % on sense roms

hi guys i've been having a problem that i cant get fixed. ive asked some people and they are not sure what the problem, and also looked in threads and the fixes dont seem to work either.
i flashed the chadogr rom a while ago from cyanogen mod 7 becuz there were certain issues i was having with it.
when i had the chadogr sense rom, the battery would continuously die in barely no time at all, and when i looked at what was consuming my battery, "display" was always using at least 80-90%, and the phone would be dead in about 3 hrs or so.
got sick of it, and went to an aosp based rom called gingerbread evo deck 1.2w. it was very good and light on resources and battery life was good WHEN I DIDNT USE THE PHONE. but as soon as i started using it battery would drop so fast, but that didnt bother me, cuz sometimes i didnt need to use it. but there were somethings that i just couldnt stand with asop.
1. GPS never worked, EVER!! (i tried all the fixes to no avail) it was always searching for satellite everytime i wanted to use navigation.
2. it had awful signal strength (even wifi), constant disconnects, and always giving me this info that im internationally roaming (wtf)
3. a couple of other things not really worth mentioning.
i said eff it and decided to go back to sense, and decided on the synergy rom after reading the thread to great reviews.
i like the rom but im back again with those "high display" use problems again.
what is causing this and how do i fix it. there was a "fix" in the synergy rom thread but it didnt work for me. it said to go to the spare parts app and uncheck the compatibility mode, i did that and im still having those display issues.
here are some pics for illustration purposes:
this is the chadogr rom (sense), and after only about an hr, its down to 65% and look at what the biggest user is

and now here is the sense rom i flashed yesterday (7/17/11) (synergy), BACK TO THOSE DISPLAY ISSUES AGAIN
sorry this is so long, pls dont bite my head off or yell at me , i dont know what else to do,
i dont have automatic brightness, screen timeout is set at 30s
im lost
pls help, and thanks alot guys

It's more probably a difference of the battery stats plotting rather than the drainage of the display. Display drains the battery most out of all the components in the phone, so that reading must be pretty accurate. If you're battery is draining ridiculously more over AOSP, which Sense ROMs usually do, than you might have a problem with the ROM or kernel themselves and not necessarily Sense, or it could be a more accurate reading for the Displays battery use. I am running Synergy Nightly 7/16 and my battery life is relatively good to CM7.1 RC1. And yes display is at the top at 66% at about 1/4 the time on(Ex. 2 hrs run time since charge, 30 mins display on). Turn of auto brightness too.

Also remember that it is displaying percentage, so the display being higher is actually a good thing. Your display uses the most power of everything on the phone, or it should be, when it is using a higher percentage of the total power available, it means that everything else is using less. The only way to get the percentage of display use down is to either turn the brightness down, or leave the display off as much as possible.

Click on display and you'll get an accurate reading of how much you actually used the display.
Synergy is awesome though, I went from 86% down to 85% when I woke up this morning. 10 hours off the charger and I wasn't even fully charged when I took it off. This thing is amazing with battery.

I have the exact same issue as the OP. I'm posting from my phone right now so when I get home I'll post a more detailed reply with pics but this is NOT NORMAL display usage. I'm getting sick of people telling me and others with this issue that its "just a percentage of what's using the battery and its normal ". Its not normal because this never used to happen to me and the display never used that much battery before. My battery life is horrible compared to a rom that doesn't do it. At most I'll get ten hours from a full charge and I can visibly watch the percentage drop as I'm using the phone. Even when I haven't touched the phone and the screen being off, the display usage will still be at like 90%.
It didn't use to happen, it seemed to just appear out of no where, the first time being with mikfroyo 4.62. I tried downgrading but no luck. I can only comment on roms that I have tried but it also happens with mikg and synergy and a few other sense roms. Aosp does NOT have this issue as I've tried a few differently ones. Currently using CM 7.1 and I'm getting at least 20 hours with heavy use.
I have been trying to get to the bottom of this for a few weeks but it seems that I just keep getting run around in circles. Now that I've seen other people are having this issue too hopefully we can get this worked out with some help. Its keeping me from using my favorite rom, synergy. I like aosp but it just can't match the performance and functionality of sense, oh and looks hehe. Like I said I will post up some pics when I get home to provide more evidence

Have you checked your wake time on the ROM? Wake lock issues are a more likely culprit than the screen when it comes to bad battery life like you described. Go to menu/settings/about/battery and look at your Up Time and your Awake Time. If they seem close to identical (even though you know you've walked away from your phone for a while and had the screen off, etc.) then you have a problem.
The most likely solution is a PRI downgrade to 1.77. Check your ROM's forum to see whether or not a particular PRI is suggested or not.

Its not a simple wake lock issue. My up and awake time are very different, just like they should be. Its not pri either cause I've changed it multiple times with the same issue. How would that even affect display usage? Every pri problem had caused high cell standby or android system but not display. I just bought system panel and I am going to let it run a monitor for a while and see if it brings up any red flags (using synergy). This is something a little deeper than a simple wake lock or radio issue.

Yep, sounds like it. All I know is that many, many phones (including mine) on gingerbread roms show very high display percentages. However, the phone lasts just as long as normal. The going notion is that gingerbread handles app and service power so much better than Froyo did that the display percentage simply has to be higher. That's how percentages work, of course. However, if your phone is dying at a much faster rate than normal, then yes, something is wrong, but I wouldn't be surprised if it has nothing to do with your display. Not that I have any clue what it might be, just sayin'.

It does it regardless if its a froyo or gingerbread rom. First rom it popped up in was mikfroyo which is 2.2. But weirdly it didn't use to do it on that rom. I achieved my best battery life (30 hours moderate usage) on mikfroyo 4.62.

I have three different phones.
Hero (rooted with CM7) - high display usage
Epic (Unrooted stock 2.2) - high display usage
Evo (rooted various 2.3 rom) - high display usage
All have high display except when I run Deck 1.2.1.
On my Evo some rom such as Sprint lovers (stock after auto root v2.5) 3.70 gave me high Android system, but most if not all gingerbread rom with the exception of deck all show high display usage including miui.
This lead me to think that high display usage is quite normal IMHO, just thought I'd share.

How high though? Mine and the OP display usage stays from like 80-90%. I can understand if its a little higher than everything else but this is extremely high. And why would extremely huh display usage be normal even if i haven't touched the phone and the screen is off? Its not normal because it didn't used to happen on the SAME rom. Like i said i used to be able to get 30 hours with mikfroyo 4.62, then this display issue came up and i cant hardly get 10 hours from a charge.

It's more probably a difference of the battery stats plotting rather than the drainage of the display. Display drains the battery most out of all the components in the phone, so that reading must be pretty accurate. If you're battery is draining ridiculously more over AOSP, which Sense ROMs usually do, than you might have a problem with the ROM or kernel themselves and not necessarily Sense, or it could be a more accurate reading for the Displays battery use. I am running Synergy Nightly 7/16 and my battery life is relatively good to CM7.1 RC1. And yes display is at the top at 66% at about 1/4 the time on(Ex. 2 hrs run time since charge, 30 mins display on). Turn of auto brightness too.

when i 1st got my evo, display was never the biggest power consumer, it was either android system, phone idle or something else.
its hard to believe the reading is accurate, when i know i havent even woken up the phone that much, currently the biggest user of my phone at home is wifi, yet that shows only like 4% or so.
oh and yes auto brightness is off too as stated on the bottom of my original post

Synergy is awesome though, I went from 86% down to 85% when I woke up this morning. 10 hours off the charger and I wasn't even fully charged when I took it off. This thing is amazing with battery.

I have the exact same issue as the OP. I'm posting from my phone right now so when I get home I'll post a more detailed reply with pics but this is NOT NORMAL display usage. I'm getting sick of people telling me and others with this issue that its "just a percentage of what's using the battery and its normal ". Its not normal because this never used to happen to me and the display never used that much battery before. My battery life is horrible compared to a rom that doesn't do it. At most I'll get ten hours from a full charge and I can visibly watch the percentage drop as I'm using the phone. Even when I haven't touched the phone and the screen being off, the display usage will still be at like 90%.
It didn't use to happen, it seemed to just appear out of no where, the first time being with mikfroyo 4.62. I tried downgrading but no luck.

One thing I noticed, in your pics your signal is very low, if your signal is low your phones gonna use alot of juice trying to maintain and/or look for a better signal.
Try checking in an area with a decent signal.

@OP...as long as your up time and awake times are diffrent Your phone is completly normal...1) when your using sense roms your continuously using your phone,so your display screen is on all the time. Hence the display so high. 2) when your using aosp roms..your taking long breaks from your phone..the flat lines on your graphs...your phone is sleeping,allowing more batt life..your in 20+ hrs of use..when your on sense your in 3-4 hrs of non stop use..it looks to me u enjoy sense more and can't put your phone down LOL..so the more u use your phone the higher your display % is going to be.

I Finally Did It! (24 Hour Battery)

I have been desperately trying for SEVERAL months to find a way to get my Samsung Epic to last ONE DAY. Many of you might say thats EASY but not for me. You see I am a POWER USER. Not one of those send a few text message, listen to some music, play a game or 2 users. I actually TALK on my phone a LOT.
I purchased a Yoobao 2800 MAH battery a couple months ago, thinking it would solve my problems and to my dismay I could ONLY get about 5-6 hours with the way I use my phone. So I began searching for apps and configurations that would help me achieve my 24 Hour goal and yesterday I finally found a configuration that works.....
My Results
Battery Life 25 Hours which included 4 HOURS OF ACTUAL TALK TIME W/ BLUETOOTH USAGE
Including 3 email accounts (2 Yahoo set to 1 hour check and 1 Corporate "PUSH" email)
A WHOLE GANG Of TEXT AND PICTURE MESSAGES...LOL
What I Have
Samsung Epic w/Yoobao 2800 MAH Battery
Running Stock Rooted EG22 (Leak) and Generation X "Green" theme.
What I used
Set CPU:
Set up profiles for maximum battery save when screen was OFF and when battery went below 30 percent
Juice defender (Free Version)
Tweaked for maximum efficiency using advanced settings
What I did
Themed everything as dark as possible (Go SMS Pro, Go Dialer, Go Contacts)
No Live wallpaper (Ovious...lol)
My Findings:
Contrary to popular belief....Tasks running in the background IS NOT the biggest source of battery drain. HAVING YOUR SCREEN ON IS! I was having NO success with any of the top task killers so I STOPPED USING THEM ALTOGETHER. All they seem to do is run constantly in the background (Even when the screen is off) killing apps that will RESTART themselves anyway after a few seconds. Juice defender works in a different way. By cutting off the data connection when the screen goes dark. That means any time Ii was on a call and the screen was dark, my data was cut off. (I dont usually need it when I am on the phone anyway) During this entire process I had a rather light wallpaper on my phone. so Im sure I could probably have saved a lil more battery if I wanted to.
Hopefully this will help some people get more battery life out of their epics. After all, whats the point in having a great phone if you can only use it (the way it was INTENDED) for a few hours.
Good Day To All!

lolz
im runnin ec05, srf1.2 rom, bright red & black theme(transmattered reds made by me) pulldown animation, stock battery, no memory mods, live wallpaper(my theme is mostly transparent so the live wallpaper is playing almost all the time), play pandora average of 4-5hrs a day, constantly checking fb xda email market(i have 120ish apps lol), & i get about 13hrs a charge...
you should try those changes on srf1.2 rom if you already havent... some people running similar setups have reported 2 full days or more...
but instead of set cpu you should try voltage control

Pretty sure when you get a phone call it shuts off 3G anyways. Atleast whenever My phone rings my 3G symbol vanishes completely.
Congrats on the 25hours though

I dont think thats true... I've been on a call using speakerphone and 4g data at the same time... I think 4g data still works if you are on a call

The key to good battery life is making sure your phone is sleeping properly when not in use. If CPU Spy shows 100Mhz much higher than deep sleep, then you got something that is keeping your phone from sleeping. I had a problem with some HP printer monitor on one of my computers pinging my phone constantly on my wifi network that would kill my battery if I let it sit with wifi on at home.

Talking on the phone and the 3g network use the same antenna, so you can only do one or the other. 4g and wifi use a different antenna so they will still work for data while on the phone.

Thats unbelievable....

Until the newest RandomRom 2.3 Hawk I had the same problem trying to get my phone to last 24 hours. Now I have the RandomRom 2.3 Hawk installed with bloatware Removed, voodoo sound V9 module loaded, busy box pro and golauncher ex with over 100 apps also. 27 hours and I still have 14% battery life and that has been after using 4g for about 3 hours, flashlight for about 1 hour(teslaLED), played games for about 2 hours combined, sent about 40 emails, texted all day(about 150 texts), browsed the web for about 1 hour, watch some youtube videos for about 30 minutes and used navigation for about 30 minutes(coPilot). That is also with weather bug auto updating every hour and gmail sync'd to do its thing automatically. I am happier than I could ever describe now...I think I will finally leave my phone alone for a while now and stop flashing a million roms since I feel I have the best made for 2.3.4 now.

I get about 18 to 20 hours of normal everyday use out of EG22 but i stay on wifi. on ec05 the most i could get is 6 hours, bottom line no matter what i tried. and thats with a stock battery.

About the battery consumption

Hello, I am a happy owner of the DHD.
It 'a great phone, but as you know, the only drawback is battery life.
I've tried several (few) ROM so far, and one with which I am slightly better is the RCMIX.
Now with this post does not go into details about what set, how to optimize (Sync off, energy saving displays, etc. ...) but I ask all your experience based on the ROM that you have installed:
1 - how to use the terminal?
2 - how long you last on a full charge and use it to do?
3 - What kind of ROM you use?
Thanks to all. I think it will be useful for someone like me, prefer a long battery life rather than three thousand graphicals functions

Battery life... it's been quite heavily documented on the DHD fora, but here we go:
1500mah is not enough for a huge screen, especially if you want to use the phone's capabilities. The versatility of this phone means you'll want to be browsing, doing emails, playing processor heavy games etc. Each to his own
So, limit the stuff you sync (mail/facebook, news, weather), or at least reduce the frequency. These things cause "partial wake locks", which stop the phone falling into a deep sleep, after which battery consumption is minimal. Watch out for wifi settings too. Search for BetterBatteryStats (by chamonix) on the Android Apps section of the xda forum for much more detail, and tips.
You should be able to get to the end of the day with a good ROM (eg Leedroid/Revolution - they are very popular, but the threads are immense, which makes looking for information difficult). These ROMs have over/underclocking built in (governors), and you can also undervolt (theoretically reduces consumption too).
Limit transitions, be reasonable with screen brightness etc.
And if all else fails, and you use the phone intensively and can't get to the end of the day, you could invest in a power pack (search Amazon for the New Trent 5000mah power pack, which costs less than €30)

my DHD lasts around 4 hrs continuous screen on, much longer screen off. IMO, LM based roms have the best battery life.
But you could always get cheap $3 batteries for the Desire HD off ebay.

Battery life on my DHD was very bad before i rooted it. I am now running RCMix3D Runny V1.3 and my battery has lasted over 30 hours with alot of use.

Your kernel? Radio? Ril?

with m0rbus called "normal usage" my phone lasts around 48h. using my rom and lordmod 7.2 cfs and my personal governor/undervolt settings.
edit: though this result is not really specific to MY miui rom. one should be able to achieve these results with that kernel and settings on every aosp rom.
edit2: with "my normal usage" it last around 24-30h. this includes gameing, emailing, testing settings for developing my rom, rebooting etc.

I've used alot of roms most of the sense ones seem to use about the same battery life better than stock (they get me through work stock needed charged at lunch) but for a week now I've been using miui I've been home about an hour played about 15 min of angry birds, watched a few min on youtube and surfed on xda for a bit and I just over 40% i think that's pretty good going.

Hi, I upgrade the ROM from the group Android Revolution, and my internet I put on 2G and work with WI-FI, GPS and SYNC ON. My battery life is working about 1,5 day.
Before I upgrade I use a Super-Wire patch from ARHD, I think this patch get this performace.
PS.: Sorry My English. I´m Brazilian.

I dunno guys.. I think all that is your subjective feeling and that ROM has no effect whatsoever on battery. Maybe small, but unnoticable. You never do things exactly the same or have battery charged exactly the same. In order to prove ROM has effect on battery usage you would have to make lab tests, i.e. make conditions the same. Moreover, if you look at the statistics of battery usage, it is clear that the most battery goes on SCREEN. And then GPS. Everything else is just a couple of %. All the talk of turning off wifi/3G to conserve power is simply not true. Just look at the statistics! Wifi takes like 2-3% of the power used, tops! The screen with it's 40%-70% is the problem, and there is no way to reduce that...

exactly....

You could always try to lower auto brightness levels by way of a flashable patch. I found that after doing this the screen was only using between 30-40% of the battery. Even so, it is the screen that always uses the majority of the battery. All the tips regarding decreasing battery by switching off syncing, wifi, widgets, etc are in my opinion a bit misleading. If you have a good radio and corresponding RIL then this will vastly reduce battery consumption whilst still being able to sync emails, widgets, etc with the wifi on. I recommend Radio_12.54.60.25_26.09.04.11_M2 and it's matching HTC-RIL 2.2.0160HM. I'm currently on Orange in the UK and this combo works best for me across several different ROMs.

Yes and no.
If you are using the device, you can limit transitions, underclock the processor (via a custom ROM), flash a patch to modify the brightness as mentioned below. That definitely will help reduce consumption while in use.
However, and this is not collected in the Battery Usage option in Settings, Partial Wakelocks are the main contributor to battery consumption. When the phone is inactive, it should be asleep as much as possible - applications like Phone, Mail, Latitude, alarms etc wake it up for either scheduled or ad-hoc events. If you install BetterBatteryStats you will see which processes are keeping your phone awake & hence in a higher state of battery consumption.
Oh, do NOT buy cheap ebay batteries. They lie about their capacity. The only battery which offers more capacity than the OEM one, is Mugen (search in the Accessories forum), it's 1500mah. That extra power could make the difference in making it to the end of the day, but it costs about $45 I think.

You think this behaviour is normal?

If I charge the phone before going to sleep to 100% and leave it on, in the morning the battery it at like 60-70% which IMHO is really too much. I have sync set to between 1-2 hour intervals depending on service, but over night I set phone data to OFF so it shouldn't matter, should it? Then why such consumption? I understand it over the day when I use it, but at night the display is off, data is off so what could cause this? It can't be syncing since the data is off....
