So I finally got rid of my iPhone 3G (jailbroken on T-Mobile), and got an HD2 instead. I've always liked Windows Mobile phones (and had most iterations), and since now there is finally some capacitative goodness on WM, I jumped on the opportunity.
And I'm regretting it already.
I'm hoping that somebody here has some suggestion that my two days of thread searching, and experimenting didn't cover.
The problem is, yay, .... the damn battery.
I left it on the charger from totally empty to completely full at 2AM. At 8AM, it was down to 85%. Ten minutes of reading e-mails, 74%. The thing is really not usable in this state.
Here are all the things I checked already:
It runs the latest T-Mobile ROM and radio (the one that just came out a few days ago).
Latest version of .NET (3.5.9).
No push e-mail, e-mail checking once per hour, weather checking once per hour.
Strong 3G coverage area, still tried out WMLongLife anyway (with no difference).
Did several cycles of full discharge, recharge.
Always check task manager, not leaving programs running.
Nothing else is set to go online - Live is disabled.
Screen brightness is set at 30%.
All charges done via wall charger.
I read every post I could find, especially fun the ones where people get 4 days of standby, and 6+ hours of heavy use. Short of loading the ARTEMIS ROM, I exhausted all options I could find. And really, it seems like people get decent performance from the stock ROM, so I'd like to stick with that for the moment.
What am I missing?
So frustrating. I can see how this sort of thing would make the average "just user" go run for the Android or Apple hills. No wonder we get stuck with restrictive babysitting technology, when others can't get their **** together. Spend $450 on a phone that can't make it through a half day of reasonable use? Argh!!
Any suggestions would be greatly appreciated.
same here
i have all the same problems my batt just sucks i figure i have to just by a new one
hey man, i was like you at first too. all my mates had iphones (i dislike apple in general) i didnt want one. At the time o2 (uk) didnt stock android phones and i had a sony x1 previously. So, i got the hd2 and...like you said was disapointed.
Changed the rom to a custom one here at xda (hdowners btw) which lasts 1.5 days (heavy usage)...never seems to get 2 full days when i use it alot.
installed a few different browsers (opera 9.7 and 10)
installed morphgear (with some amazing landscape skins)
fpsece (i found time crisis to be the only actual playable game)
coreplayer
and found it a awesome phone...changed my views on it. Try some custom roms and see what you think...usually you will go mad installing themes, skins, apps...just go wild and keep the ones you really like/work in a seperate folder. Then reflash and install the best only...thats how i done it and i now love this phone
good luck, im sure the rest of the forum will give you some advice.
wayandrs: The main thing that will help is by upgrading the ROM even if it is to stock 1.66 (the latest UK one available) then you notice a large difference and even more so with some of the cooked ones. Other things to note are the WiFi, make sure it doesn't be left on (and only turn it on if you need it) it proper drains the battery. Without knowing your habbits with your phone it is very hard to come up with decent suggestions that hasn't already been posted elsewhere.
I can safely say I get 2-3 days use out of my device but then I don't use it all that much (anymore), don't forget as it is a new toy for you, you will keep playing with it seeing what it can do, this will soon die down (as it always does) then it will be better.
there must be something wrong with your device or battery.
mine lasts for about 3-4 days while middle use. i think for such a powerful and huge device, this is more than respectable.
heavy use...mh...i would say it lasts minimal 2 days, sometimes more.
did you write a complain to t-mobile?
DN41
The battery will improve after a week or so .
Note : charging your battery the first time for only 6hours isn't much , the first time that i charged my battery i left it charging for 24 hours.
Updating to the latest ROM and Radio helps .
I have two suggestions:
1) Take your phone back to where you bought it and let them deal with it. I get at least a full day with heavy use which is to be expected from a high end device with a 4.3 inch screen. I spent a few dollars on a car charger and an extra wall charger for work, sorted.
2) If you want help on these forums leave out the useless complaining about what a rotten device you have. I think I speak for many contributors of this forum when I say that these kind of posts are getting old and wearisome. You will be more likely to get polite replies with inteligent suggestions if you simply state the problem without moaning about the horrible mistake you made in being seduced into buying an HD2. I have purchased phones that I simply did not care for. I returned them.
First step: Flash a decent ROM with most of the performance/battery tricks in there already. Many of these ROMs are constructed from the best (often most battery efficient) parts of multiple ROMS.
Touch-X, Energy, Artemis, CleanEx, etc. All are excellent (though I favour Touch-X myself for a great utility/preformance/battery balance).
Second step: Flash a good Radio that works well in your area but also works well with the ROM/has decent battery life. You'll need to research this for your chosen ROM.
I use the Korean radio in UK. Good quality/signal/battery life.
Run it for a few days, charging to full and emptying the battery before recharging to full again. Do this for 3/4 days at least.
Those changes alone got me upto 2.5 days standby and 4 hours usage (thats movie playing for 4 hours with 100% backlight in a hotel room). Good for a smartphone and longer than my friends IPhones.
Other small programs like WMLongLife, adjusting down the backlight automatically, added another .5 days to standby (though not much to active use life).

Yes, sorry I fell back on the usual retoric.
I do wonder though if when someone buys a new 'Toy' that they dont hammer it to start with for the 'joy' and never think of the consequences.
I like you, no matter which phone I own, being a businessman and needing maximum performance have a charger at my bedside (the phone is my alarm) and also connect it to the car charger when driving.
I wonder if many of the people that move up from a basic Nokia phone (or similar that can last a week) realise what is involved in powering all the functions they require?
Please don't quote iPhone as it dunt do half!
try elegencia rom v 8.5 and reply back
I use the stock rom 1.66 from the beginning and check my mail automatically every 30 minutes. Now and then I check some websites and download cabs and use HSDPA/3G and WIFI if available. My battery is 100% in the morning and 70 percent in the evening. Not bad at all. The first 12 times I fully charched the battery during the night.
I use Bandswitch, which automatically disables my connection within 30 seconds. This is the most important and useful tip! You don't need a custom ROM to solve the battery drain issue.

+1 - Lovely ROM
it looks like you have not a windows phone before
Thanks.
Thanks for the ROM suggestions. I'll try a few more days of deep cycling the battery to see if that helps - if not, I guess I'll try a custom ROM.
And yea, to those 'get a life' and 'don't complain about Windows phones' posts, whatever. I've owned Windows Mobile phones since they first came out, and it's just frustrating that the out-of-the box usability hasn't gotten any better to this day. Looks at the cool people that actually manage some constructive feedback - they are who make XDA forums great. Thanks guys!
A new 1200 battery is 15 pounds (the official from HTC) as a backup. I personaly have bought the extended battery 2400 and it is great. The default battery doesn't last the full day for me because I use it constinuosly as mp3 player , brownsing and video player. I mean, you have options.
ROM
I'll be trying the Elegancia ROM.
That is, once I find a ROM with 2.8 SPL that works on my 1024 version of the H2, to reflash mine so I can get HSPL to work to flash.
I've always really liked Windows Mobile for its flexibility and massive base of developers ... on the flip side, I've been screwing around with this thing for several days now, trying to get a phone that can last through a day. Ahhh, the bittersweet experience that is WM.
I get at most 2 days combined cycle out of my stanard battery and i've had my phone for about 10 days. It came with the stock 1.66 rom but i've run through the tips and tweaks threads so the phone ui is faster and a bit more usable. One of those is a replacement task manager that disables smart minimize in favour of actually closing programs. I've also set the weather software to update every 3 hours because tbh you don't need it to be any more often than that. I do use the wifi alot but i do turn it off when i'm not using the phone. i have also noticed with my phone is if the wifi is connected to an access point for more than 5 minutes it will automatically disable the 3G connection and turn it back on when the wifi is disabled.
for the first couple of days i was completely discharging the battery and then charging it for about 12 hours. this seems to have been the most beneficial. i also will not put it on charge unless it really needs it.
hi, from experience, 3G medium usuage.. 4/5 a day.
If you disconect the 3G connection when not using, it will help.
And of course if you go on GSM instead, one day is not difficult..
battery killer :
1) constant 3G activity
2) Watching video. Worst, video on 3G !
3) games, especially the 3Ds ones or high on processing like the Tower simulation game.
4) bright screen
5) bluetooth
From my experience, from a fresh flash, my battery improves as I get to use it longer and longer.
take a look at your data sync like weather and stock and also check the social networking sync.
My battery made it to 1:00 o'clock today with the new 2.2 update that i did last night. It normally lasts till 11 - 12 at night. Whats up with that?
FYI - All the same apps,widgets, and settings
**UPDATE**
Doing a factory reset fixed the problem for me!!

Strange, I'm sitting at 75% after 5 hours off the charger and using it for moderate text usage (probably less than 80 messages today). Usually around this time it's sitting closer to 60%.
i have the .3 update and went from about 24 hours to about 8-10 hours. Battery life cut in half. My friend who has .3 is having same issue too. So much for increasing battery life.

Wow. Have you searched the forum to see if anyone else has the same issue? If not I hope it's not an isolated incident. Then again if it's isolated maybe you can get support on it better...? Good luck finding a solution.
You gave us zero information to help you. So thus, you will not get any help.
There are about a billion threads on here about battery life and how to tweak it. When you flashed 2.2 you will need to do those steps again.
yeah some people are reporting bad battery life after update. most people i know are on .3. don't know if .6 fixes this hopefully we get update soon
I did a test last night. Dropped 13% between 1130 and 3:30am With wifi on (got up cause of baby), then only 10% between 330 and 8am with wifi off. So a drop of only 23% overnight.
That's with one exchange account, one gmail account (both syncing as items arrive), htc news set to not sync, but newsdesk and feedr both syncing. Facebook for htc set to sync contacts only.

I had the same issue on all 2.2 ROMs I tried.. i am now going through the apps one at a time to see which one is the issue.
right now I am 7 hours in and sitting at 75% very light use ( read about 7 emails, 5 new articles and little to no Web surfing). installed 10s so far other than the standard with Fresh latest ROM that is.
I've actually had very good battery life, I'm running the .3 release. Battery life for me has been very comparable to running Baked Snack 9.6, with its underclocking/undervolting power save features. Moderate use of the phone for 8 hours (wifi, browsing websites here and there, one navigation route, texting, bunch of short phone calls, playing some games), my battery was around 65 or so, same as I had before for similar usage.
I did do a full wipe though, and haven't calibrated my battery since updating.

I am just stating a observation on my part. And i know all the little tricks of how to get better battery life. But like i said, before the update i was getting a full day of battery and now after the update i am getting half. With the same settings and the usage on my part.

maybe because some of the htc sync stuff that you might have disabled before re-enabled.

This is not directed at you personally, but at the words you chose to use:
I am sick and tired of "tweaks and settings and cutting things off." I used them and got over 30 hours on both DamageControl and Fresh.
I paid Sprint/HTC good money for this awesome phone (and am committed to pay them a whole lot more over the course of the next 22 months).
While I can understand the 4G thing, why should I have to cut off Data-WiFi-Bluetooth, power down the CPU, not use it a lot in order to get... in short, drive it like a Toyota Prius when then phone is billed as a Maserati? Why should I have to try out this app and that app(Overclock widget, SetCPU, System Manager, Task Killer, Autostarts etc which all use battery too) in order to get the phone to do what it should have done on June 4, 2010?
Most of the battery draining apps and widgets come pre-loaded with sense (i.e. the Favorite widget, Friendstream etc). Why should I have to resort to rooting my phone or not using it in order to get the thing to last all day?
I'm keeping my EVO cause I love the device, but maybe Sprint/HTC need a little of the medicine that Jobs/Apple is getting in the form of lawsuits due to over-promising/under-delivering.
/off_my_soap_box
You should send that rant to HTC and Sprint... I think we all stand behind you on that one.
there are lots of reasons a battery might not last. there are way to many tweaks out there which is why you have to do it yourself.
First set the phone up like you normally have it and test the battery life. if you can live with it your good. if not start looking at the settings. Read the tweaks but don't just take them as golden as everyone is different and uses their phone different. Ask yourself if you real need that setting. (I like my screen time out at 2 min. do I need it NO 1 min is fine). When done with the settings move to the apps. load the flat ROM no apps and run for a hour and track your battery life. then add the apps 1 at a time or in small groups and let run an hour and track. there are was if find what apps are using the CPU or Battery but many do this normally and yet don't effect the battery much. Only way i have found is old school add them one at a time. When you find a bad one decide if you need it or can find a replacement.
I am done with Sense as Launcher Pro Plus is awesome and now with the only Widget I was missing (Calendar). Once I done going through my app list I will create a new thread in General to list the bad application I found unless someone else has or does before I done that is.
From what I have gathered from using .3 that apps auto sync/update on their own now with "always on mobile data" turned off. if you use advanced task killer, do a kill of all apps then turn the screen off. If you wait for a few minutes and turn the screen back on you will notice that apps like news, messages, Twitter, Facebook clock, weather and others will be active. From what I gather the decrease in battery life is from apps like those will send/receive data on 2.2 while on 2.1 apps would not update/sync until you manually refreshed or opened the app, as long as you didn't have "always on mobile data" enabled.
Edit: this reason is why I uninstalled fring. Just too bad I cannot uninstalled qik.

It is a mini-computer. You don't use it like a "phone" anymore. You shouldn't expect more than 15-20 hours on it. Do you get angry when your laptop runs out of life after 5-6 hours? If you don't want to do tweaks, then don't. Keep a micro-USB at your desk at work and charge it there. I, myself, enjoy rooting so I don't mind tweaking it. I also get 30 hours of life on it due to this. If you don't like to do that, you get what you put into it.

Again, you have unrealistic expectations for a smart phone it seems. All I have is Set CPU running on my phone with Fresh 3.0.1 and works just fine. I still use my phone like a "Maserati", it just lowers the CPU when the screen is powered off. That is like saying you want your car to idle when you get home at night until the next morning. It doesn't change how you drive it, just how you store it in the garage.

You don't have to use them though. You can remove friendstream and go with either the twitter or FB update app or go without either and just check facebook like anyone else. As far as favorites go, you don't have to use that either. You can just make shortcuts to each person's phone number on that same screen if you think that is sucking all your battery life. There are always other options or fixes, but again you expect the phone to come out of the box perfect without any customization. You are getting away from what Android really is. Something tells me the Iphone would have been more your liking since it is built around lack of true customization. This isn't a rip, but just saying if you want cookie cutter phone reliability, it is hard to beat Apple. If you want the ability to tinker with the phone, the power to change things, and the power to make your phone yours, then that is more Android.

I can understand your frustration, but nothing was ever promised to us on purchase. I don't remember anywhere seeing something saying the battery would last 30+ hours out of the box. Apple had an actual structural issue with their phone, that is why they had the lawsuits and PR nightmare. This is just the phone doing what most would probably expect(at least anyone who had a G1 or Hero or any of the earlier Android phones). You love the device enough to keep it even with your frustration, something tells me it works quite well for you. But I have yet to see any over-promising/under-delivering on the Evo myself.
And no, I don't work for Sprint or HTC. And no offense meant to you as a person, just I didn't understand your motives on your frustration. Guess we will have different opinions on the Evo so far.

I had the same battery problem after updating to 2.2. After 3 hours my battery was at 50%. Normally it'd be at 50% after 9 to 10 hours of usage.
I did find that some settings had been reset. Once I turned off all the crap syncing, gtalk logging in, Sprint Zone, etc my battery usage has seemed to flatten out.
I made it an hour and only dropped 2% which is much more like it. This is all with very little usage going on.
Buy a new battery! Best solution!
No joda!

very funny just pluged my phone in using flipz newest after 19 hours
make sure you are signed out of googletalk !!
I know one of the major concerns regarding the EVO has been the battery life. It was the reason that I rooted my phone in the first place, granting me the ability to rip out bloatware to conserve battery life. It wasn't until Saturday that I got around to noticing the rooted version of the official 2.2 release. All I did was download the ROM and delete all the apks/odexes I didn't want from the zip file, load it, charge my battery. Currently, I've been going almost 70 hours and am still at 60% battery life under normal use. That's a significant increase. The best I ever got was after the rooted second OTA at about 40 hours pushing the battery down to about 10%. Have other people been seeing battery life increases like this?
No, we have not. Quit bragging..
Serious? Experiment with more use of battery life

I have noticed better battery life but not as good as you say. I've tried many different roms and kernels also.
do you actually use your phone on a daily basis? do you have any emails being synched? gmail? exchange? do you use facebook? browse the internet every 4-6 hours to see whats news on BGR or usatoday/cnn? do you text msg.. etc etc
if i leave my phone sitting i can have great battery life too, don't get me wrong i'm not trying to bash you, just trying to understand how you use phone so i can guage if this can apply to me. i know people who haven't installed one single app on their evo yet, usuage is different for everyone.....
Did you say 70 hours? Is that a typo? That's 2.916666666666666666666667 days and you've only dropped 40% battery life?

I was super nervous when I suggested the evo to my aunt's family over the iphone 4. AT&T doesn't even have 3g where they live though. Asked them if they had any battery issues with their 4 evo's and they looked me like I was crazy. Then I found out that they all only had like 1 app installed. They get great battery life on their stock 2.2 phones. If I play around with my phone, and I do, I usually am riding the red line by the end of the day.

I don't use my phone that much for phone calls, actually. Several hundred texts a month, several megs of data a month. It's synched with gmail, I have a separate phone for everything else (work). At work I'm always on 3G, at home wifi. The only time it's not actively connected to a network is when I'm sleeping (sleep profile is only for the alarm). Outside of synching, I use the internet for random browsing periodically, usually sports related, or anytime I'm not at home or work and want information.
When I put this ROM on, I stripped out over 60 files from the zip file (almost 20megs) and only installed about 8 apps that I use regularly. After I configure my phone for all my settings, I remove all the widgets everywhere and setup just three screens with my widgets.
Even though I'm in Dallas, I rarely use 4G (the higher wavelength doesn't penetrate well in the urban areas I work or live in), only turn on GPS when I'm using Google Maps to drive around, and never have both wifi and 3G (Mobile) on simultaneously. I have my profiles setup so that the only time my screen brightness is above 0 is when I'm in my car or on a need basis (separate Bright profile).
I probably would have rooted my phone eventually but I did it about the third day I owned it because of the battery life. Most of the settings and ways I use the phone revolve around making sure I don't tax the battery. My real goal was being able to leave home for more than a day and not having to worry about minimizing my usage of anything, and now it seems I've easily done that.

Hey I did not even know you could get that much time out of a single charge.... I am going at least 17 hrs before empty but thats enough for me in a full day. Hey honestly a car charger is on $13 at Walmart.
well i tried the "shut the phone off" mod and ive been getting weeks of use out of my phone on a single charge.

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?
turn off gps when not need
data when not needed
Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps
also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running
@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks
Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.
I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.
just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery
My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Gingerbread is Android v2.3. Froyo is v2.2.

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.
i owe setcpu and screen off seting for my battery life
I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.
I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!
The Short Version:
Stock froyo downloaded from Samsung's website- My battery would die at work at around 1600, after being unplugged at 0600. We will say it lasted about 10 hours. With minimal usage, with looking at my battery reports my screen was used for maybe 15-20min.
Post root/Midnight ROM 4.2- it is now about 1600 and I have about 90% battery life left with 22min of screen time being used with obviously minimal usage after 10 hours.
Long version:
I was getting fed up with my battery life on my beloved epic and not being able to use it at all. So I decided to do some research and figure out this rooting and ROM flashing business. I KNEW it was not because of the apps and such that sprint blames the poor battery life on because I would monitor that and not use any at all while at work just to see and prove them wrong. I have the same apps installed post root as I did pre root with the same sync settings.
So in other words it is highly depressing that they put so much crap on this phone stock to kill the battery life with not even being used.
I am so happy now, I can actually use my phone without having to worry about being dead in 2 hours.
Thanks for everyone’s help with my flashing question and thanks for this great website as a resource.
Time to try out some different ROMs!
Sounds to be like your phone might of been fighting for a signal or something, maybe a PRL update would of fixed it... I was getting well over a day with the sprint rom.. and now with ACS Rom I get a little better.. but not much..
anyways.. congrats
