I read on another site to simply turn off the always on in the wireless settings (not the background data in the sync menu) and my battery life has at least doubled. I was worried that my e-mail would not download or other apps would not work, but all my email still comes. The trick is that while your phone is in sleep mode it does not look for email, but once you use it the phone will get your email. Unless you MUST get your email right away, I would highly recommend changing this setting. All input would be greatly appreciated, I want to see if my good luck is working for other people. On a side note I am using Fresh ROM 2.0d.
Could you post the specific path to the setting you're talking about?
If I set my wifi to anything other than "never sleep", then once my phone goes into sleep mode I have to follow a long, convoluted, pain in the ass procedure to get wifi to work at all.
Hopefully that's not the setting you're talking about?
I posted this exact same thing in another thread two days ago. I was so stoked on my battery performance that I wanted to tell others. It's incredible the difference it makes! If you want even better performance go into Settings>Location...uncheck the use wireless networks box, and check the use GPS. Believe it or not the GPS uses a lot LESS battery life to detect your location than the wireless networks.
I'm getting like 2 whole days out of my phone now after doing these things...and that's with pretty moderate use. Hope other people try it out too.

where are these options?
I agree, I used the GPS as well, not the use wireless network. I forgot about that one. Your phone will only use the GPS when it needs it, not all the time like we used to think. The exact settings are at MENU/SETTINGS/WIRELESS & NETWORKS/MOBILE NETWORKS\AND UNCHECK ENABLE ALWAYS-ON MOBILE

This will vary from person to person. It will depend A LOT on how good your coverage is in the spot you're currently at.
GPS is GPS. It will require the same amount of juice anywhere on the planet.
Cell chips are different. They are hardcoded to give more electricity to the radio circuit when the signal is weak, for obvious reasons. So if you have a cell tower in your back yard, then yeah, you'll get great battery performance relying on cell based options. If your nearest cell tower is 4 miles away, and you're one of those people that loses signal when you go into your basement, then telling your phone to use cell info is only going to chew up battery even faster....
no thanks. This isn't a fix, it's a pref change.
Fix would mean that everything stays the same and you just get better battery life.
But, good advice none the less, just not for me.

Yeah, people on the forum use the word "fix" WAY too quickly.
"Fix" means everything works like you would expect, and like it should. Around here, people use the word "fix" when what they really mean is "here's a half-assed workaround that's a complete pain in the ass, but it will get 10% of the people by until something better comes along...."....

+1 - 6 minutes and counting to receive a test / text msg, while phone is sleeping. Nice the know though, if I need to really trade connectivity for battery duration. I should test whether sms polling is tied to the email polling interval. Cause it ain't interrupt driven with this setting.
edit: i know it's not really sms polling, but rather the lack of an interrupt(-ion of sleep).
Yes, you are right, it is not a fix, but a great way to increase battery life and like I said, everything works the same. I get messages the exact same way and email will go straight to my phone once I use it.

You sure about that?
When my wife sends me a text, I want to see it 5 seconds later, not 5 minutes later.
That may not matter to you, but when you make a statement to the whole world, you have to realize that some of us care about things that you might not.
How thoroughly did you test before you decided to say "everything works the same"?
Did you really test EVERYTHING? Or did you just test "everything that matters to you"?
I used to turn off background data and stuff on my stock 1.5, and I was thrilled I could actually leave it on with 2.1 so I wouldn't have to wait for google voice texts and gmail to come in. With 2.1 I can go the whole day with moderate usage and still have 40% at least left when I go to bed. Let it charge overnight and I'm good. This is good to know though if I am out in the sticks in a pinch and need the extra battery.
maybe it's different in 2.1 but in 1.5 i tried turning off the "always on" setting under mobile network settings under wireless controls but i found that after a while the phone will fail to restart evdo upon awakening and the only way to fix it is reboot. Never tried it on 2.1 but to me between the time on without signal fix nd upgraded radio i get all the battery life i need...
I get messages right away. I just got another one, tested it with a friend and it came right away!
On a side note, messages and phone calls have nothing to do with the internet. Remember we used to get text messages and phone calls way before smart phones.

But at what cost?
That's the big question here. Are you 100% sure that you're not missing any communications, or having them delayed?
I'd LOVE to have better battery life, but when it comes down to it my phone is a communication tool. If any battery tweaks delay messages, then they're WORSE then useless, they're actually harmful.
If I wanted to use my phone as a half-assed replacement for a PSP, then I'm sure I could squeeze some amazing battery life out of it, too. But above all, and with NO compromise, I must be able to send and receive communications instantly.
That's what a phone is.

Have you rebooted while in that mode?
Yes I have rebooted and just did another test. Got the text right away. Even more interesting is I have a program called Mobile Defense which can find your phone if it is missing and that works as well since it is all done through text messages.

Hi everyone!
I'm having a tough time deciding whether to get an HD2 or a Nokia N900, mainly because of one main feature on the N900: As far as I can tell, the Nokia N900 allows you to stay online (Instant Messaging, VoIP) permanently, even when the device is in standby - so ICQ, Skype, SIP, MSN are all connected, and if you get a new message or a call, the device will notify you.
I haven't used many modern WinMo devices, so I'm not sure if anything similar to this is possible with WinMo 6.5 (I've used WM6.5 ROMs on my Prophet, but I'm guessing a lot of features were stripped out to make them run at all )... is it possible to do this on the Leo?
I want the device to _always_ be online - if there's WiFi it should connect to that, and if not then it should connect to cellular data. This should obviously also be automatic, so that I don't have to manually log onto the WiFi every time I get home or to university...
Is this use supported? Or would it be more of a hack that runs down the battery like crazy (IIRC you can turn on WiFi permanently, so that it doesn't turn off when you put the phone in standby - not sure if the apps would stay connected, though)...
Thanks in advance!
I think the HD used to turn wifi off when the phone went into standby (I don't think I ever used wifi), but it used to stay connected over 3g for IM and the like when you turned the phone off (stand by)
Oh really? I thought 3G was turned off too... well, I guess that's a step in the right direction.
Anyone know about WiFi and automatic switching?
By default the WIFI is switched off when in standby, but it's possible to change it.
However, having WIFI always on will drain the battery completly.
Regarding to the automatic change, no idea!
And there's no way to lower the WiFi signal strength enough so that it doesn't drain the battery? What if you set WiFi power mode to best battery? On my Prophet it's unusable because the signal is nearly nonexistant, but I was hoping that they'd have changed this for the HD2...
Ideally it'd lower the signal strength as far as possible without dropping the signal when in standby, and then power up to a sufficient speed when the device is actually on...
Wi-Fi only turns off if you want ot too. You can change the way Wi-Fi works in the settings and let it be always on, even if you turn off the screen.
Is this new on the Leo?
Does that drain the battery quickly? Or is it in a low-power mode?
Even with the Best battery setting it won't last too long, I'm afraid. Or, as you have said, it won't have good enough reception to actually connect to anything.
I have no idea how this is implemented in Nokias, it actually sounds like a kind of magic if you're saying it doesn't kill the battery.
I've never heard about an automatic switching solution (or even about the problem, for that matter). It's relatively easy to implement periodic polling but even that will have serious adverse effect on your battery.

It's been on WM since times immemorial - it's a registry setting, and there are programs that allow you to change it without manually tweaking your registry.

OK, so it's the same feature that's existed for a long time... I thought it was something new, that actually made sense (i.e. didn't drain the battery so frikken fast...).

Sure, but you'd also drain your battery without noticing. I would certainly be cautious about it - I can connect to WiFi at work, at shopping malls, cafes, and sometimes even in the streets. I don't want to end up being unable to make a call because I saved a couple bucks. But maybe that's just me...
BTW, I did a quick poll here at my office - all Nokia owners have this feature disabled, they say it drains battery rather quickly. This is not in any way a scientific research, but I don't believe in miracles anyway.

Uh... what Nokias? I doubt it's the same thing, because the N900 is the first Maemo phone
E-something Nokias primarily - they have this auto WiFi feature, don't they?
Don't know anything about this Maemo thing you're talking about, obviously.
http://maemo.nokia.com/n900/
That's what I'm trying to decide... N900 or HD2
I leave MSN loged in on my diamond all the time. Wifi is on. it turns wifi off in standby, but msn stays logged in over the normal network connections, I alerts me I receieved a msg in the same way it does with a text. When it comes out of standby it auto reconnects to wifi.
Does that work on Fring as well?
how can I turn it off so I can save some battery...

I'm sorry but don't you think that's too many clicks?
I realize that this may not be the popular thing to say around here, but I came from an iPhone 3G. Contemplated getting the 3GS but decided to give WinMo one more try and placed an order for a HD2 just now via DeviceWire.
But getting back on topic.. in the iPhone jailbroken world, there is a fantastic app called "SBSettings". It gets activated by a swipe near the top left area of the screen. From there, you could turn on/off toggles for things such as bluetooth, Edge, HSDPA, rotation, autocorrect, etc etc. People are building other toggles as addons for it all the time. But something like that should also exist for WinMo.
Now that I'm a WinMo newbie (my last windows mobile phone was a PPC-6700 and I swore never then to buy another windows mobile phone again). So there might already be another app just like the one that I'm describing. But if there isn't, it'd be great for someone to build that software. I'd certainly be willing to pay for that kind of conveniences!

Sure, if this was a setting people used one or more times a day, like turning wifi/bluetooth on/off.
How many people will ever even want to switch from the automatic default? 1% who are looking to save battery at the expense of speed? I'm sure there'll be some crazy control freak who wants minute-by-minute control of this, but who cares?
For 99% of people auto-3G degrading to 2G when 3G is unavailable is exactly what they want. For 0.99% of people they'll want to switch to pure 2G for battery purposes, it's a one-off action done on day one. It's easy enough to find in phone settings.
Who cares about that last 0.01%? If they're that bothered they can pay someone like me to knock up a switcher app.
I don't own an HD2, but I wouldn't be surprised if this could be speeded up a bit. On my Touch Pro2 the normal route would be Settings/Communications/Phone/Band (at the bottom of the screen). But the thing that gets launched when you go through that sequence is actually a programme in its own right, called CMBandSwitching.exe (resident in the Windows folder). So if you make a short-cut to that programme and put it in the Start Menu, then you can jump straight into it. Maybe there's a similar trick on the HD2?

Nice find!
So I am at work, looking at my N1, and I'll let you all tell me if you think there is a problem...Since a full charge last night, my phone has been off the dock for 2h9m ...
In that time, my battery has dropped 14% already. The biggest culprit...the display...with 59%...despite only being on for 15m. I always use it on the middle brightness setting from the power bar. Ive lost basically 1% for every minute the screen has been on. At that rate, my phone wouldn't even last 2 hours turned on.
Am I being paranoid? Do I have some rogue program sucking battery life? Your thoughts?
Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

See what the figure for 'running' is, if it's high, something is stopping the phone sleeping. Should that be the case, chage the top drop down box to 'partial wake usage' and see what is to blame.

This is the complete opposite of what everyone else will tell you.
Most people say to force 2G (Edge) because it'll save battery over 3G. There are reports that WiFi will use less battery than 3G though, but not as good as 2G. Google even says this on the screen where you force 2G.
Push Email will require a constant polling on the internet. Since Android is a web OS, its probably connected to the internet anyway, but you can disable Auto Sync and Background Sync to save battery (once again, Google says this on that screen).
I agree with #1 and #4 though. If you don't want to do the lowest brightness setting, try the Auto Dim, it seems to dim it a lot more than my old Windows Mobile phones did.

Battery Drain
My phone would drain 15% battery in 1 hour just being idle witht he screen off. I dialed *#*#4636#*#* and changed the option from WCDMA preffered to WCDMA only. When I don't get a 3g signal (not often) I jsut go back to that and set it to GSM only. For one reason or another the WCDMA preffered SUCKS THE BATTERY!
4 hours of the phone being idle and only 5% battery drain! DO IT! IT WORKS!

You need to be careful of this. The point the video made is that if you download something OF SIMILAR SIZE, you will realize battery gains by virtue of the fact that what you are downloading/uploading takes exponentially less time to retrieve. The real question is, if 2 phones are both casually browsing for the same amount of time...without worrying how much information was actually transferred...one on Edge, the other on 3G...is there a difference in battery performance?
What the video said is just common sense. If I am going to send you 20 MB file and one way takes 2 minutes to download it and the other takes 10 minutes to download, then OF COURSE the 2 minute method is going to be more efficient. So you can download on Wifi where it might take x amount of time, compared to 3G where it takes 5x or edge where it takes 10x. Thus, if the file size the person is going to download is known, then of course it makes sense to tell them to wait until they are on wifi. However, many of us casually browse, on the spot, without regard to the type of connection we are on.

Yeah, what you just said is right. But still you are saving battery up! Plus I wouldn't use edge at all in my N1. What's the point of having almost everything disabled so I can receive calls?
I remind you that while edge is sending/receiving data you cannot get any calls

Thanks, I didn't know this, for the info this thread is full of great stuff...
1) middle brightness is very bright. I'm sure you can live with 25%. Display brightness will always drain battery like mad.
2) 3G power use is usually decent. The N1 has terrible RF so it might be fighting 2G/3G. That will cost you a lot of power. If you're getting full 4 bars 3G everywhere you go even underground, you might be ok, but in low reception areas, it's gonna drain your battery struggling to boost power. Bigger issue during a call too.I notice this on my Milestone. The N1 completely fails at 3G while my Milestone fights for it. As a result the Milestone gets quite hot.
3) There are sometimes apps that run in the background. Some people insist task killers aren't necessary, but lemme give you an example. Stupid Speedtest program failed to acquire my location. After a test, you can't really exit, so you just hit home. Droidforums fanatics will always repost that link to that one thread where they talk about memory and its ok to not have to kill an app. Think again. The GPS turns on because of Speedtest and it keeps trying to acquire your location. Gotta kill it with a task manager or that thing will kill you. Or a webpage. I've heard of people going to some site that keeps refreshing. Oh good luck to your battery. Make sure you close these things. Use a task manager. Sometimes Facebook or Twitter might be the culprit even if your refresh rates are awfully long. I do not understand this phone sometimes. At times I feel that multitasking/memory management on Android gets you into more trouble than if you just flat out restricted it like in the iPhone. I'm not saying the iPhone's restrictions are the way to go, but Apple knew what it was doing. There's a reason Android phones gobble power and pull data like mad even when you aren't aware. Random apps sometimes start. Facebook widget refreshes even though the app itself is set not to auto notify and to update on its own. So with so many things running loose, its quite easy to see why your battery can go down so fast.

2) 3G power use is usually decent. The N1 has terrible RF so it might be fighting 2G/3G. That will cost you a lot of power. If you're getting full 4 bars 3G everywhere you go even underground, you might be ok, but in low reception areas, it's gonna drain your battery struggling to boost power. Bigger issue during a call too.I notice this on my Milestone. The N1 completely fails at 3G while my Milestone fights for it. As a result the Milestone gets quite hot.
3) There are sometimes apps that run in the background. Some people insist task killers aren't necessary, but lemme give you an example. Stupid Speedtest program failed to acquire my location. After a test, you can't really exit, so you just hit home. Droidforums fanatics will always repost that link to that one thread where they talk about memory and its ok to not have to kill an app. Think again. The GPS turns on because of Speedtest and it keeps trying to acquire your location. Gotta kill it with a task manager or that thing will kill you. Or a webpage. I've heard of people going to some site that keeps refreshing. Oh good luck to your battery. Make sure you close these things. Use a task manager. Sometimes Facebook or Twitter might be the culprit even if your refresh rates are awfully long. I do not understand this phone sometimes. At times I feel that multitasking/memory management on Android gets you into more trouble than if you just flat out restricted it like in the iPhone. I'm not saying the iPhone's restrictions are the way to go, but Apple knew what it was doing. There's a reason Android phones gobble power and pull data like mad even when you aren't aware. Random apps sometimes start. Facebook widget refreshes even though the app itself is set not to auto notify and to update on its own. So with so many things running loose, its quite easy to see why your battery can go down so fast.

I'll second this, I never used to use a task killer as I figured it was just extra drain on the battery but after running across some rogue programs that kept running after being closed and draining the heck out of my battery I decided to install taskkiller and set it up to autokill apps when the screen goes off.
It's really easy to setup just install it from the market then use it to kill everything then flip through your homescreens make sure everything is up and running and go back into task killer and add everything there to the ignore list and turn on "autokill when screen off" now you don't ever have to worry about rogue apps killing your battery again and everything else will function normally.

Yeah, what you just said is right. But still you are saving battery up! Plus I wouldn't use edge at all in my N1. What's the point of having almost everything disabled so I can receive calls?
I remind you that while edge is sending/receiving data you cannot get any calls

yes you can, the phone will stop whatever data it's processing and take the call.

I'm sure 100% that while phone is receiving data over edge you wont get calls. I know because I had push enabled and afterwards I was getting SMS from my carrier that I have missed calls. It might say "ey sb is trying to call you" and then stop data transfer but for sure your will miss first call if someone is trying to reach you several times.
Check it out yourself.

Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

there are a lot of people who say do not use a task killer, including google devs etc.
i used advanced task killer for the longest time, being used to needing one as a WM user before getting my n1. after reading various posts on the issue, i tested without and my battery life increased.
i use juice defender now as well to turn off the apn and wifi, based on speeds/location/etc
have it set to prefer 2g (dont get 3g at home)
screebl also setup to turn screen off when not in certain position in hand
last one is setcpu (need root for this though) underclocking the cpu (including advanced setting and profiles i have set)
lowest setting for brightness
also keep gps off unless needed
i hit about 24hr from unplug til 10% w/ heavy useage, wifi on all the time (although juicedefender handles when its on/off)
just now went to kmobs UV kernel and testing that to increase my times
i've done a 24hr test from 100%>10% based on each app i've mentioned
I think while we are on topic of battery life.. for those of you who are rooted. Here is another link that I would recommend. I used these on my HTC Dream and works great on the Nexus One. Increase your battery life 10 fold.
Your Tube: "Get Better Battery Life" by droiddog

JK6 is what I have been looking for. Everything works in this build so far, the quadrant scores are not up to snuff yet, but the rom is snappy as hell. Still getting 60+ fps in Quake3. The issue about the call output not working when you call someone when connected to a headphone or tape adapter with no inline mic is gone. Like I said, when custom roms are built off this base, it will only get better. But if you were waiting for a great Froyo Rom, this is it.
Sorry wrong forum...
Like to to this as well. The battery life and signal strength on jk6 is excellent with out any tweaks. So far so good i feel with a few apk changes here and the there i could use this and wont feel like im missing anything as far as a smartphones goes. that being said i cant wait for tw, eugene or cm6 because this is a hobby
seems strange that when any of the developer starting to mess with the kernel, the battery life goes down. It happened with Cyanogen and it happened to Eugene as well. Anyone got any idea
Additionally, finally have true playlist support in the music player!
One downside is that the Option to enable/disable screen staying awake when connected to power is gone. It is permanently enabled.

Even though it is a downside, you can manually turn off the screen when you charge these power hunger beasts... All else is absofunkytootly amazing.
Yup. I created a word. Thats how much I'm excited about this rom.

Yes, battery was at 60% at 11pm last night!!! 60%!! Signal issues are also gone, GPS is working great, and I am actually getting a usable edge connection now (120kbps / 80kbps) when in areas of suck. Radio update has been incredible.

I wasn't clear on that, when it is plugged in to the computer is stays on as it detects a USB connection. It's possible this only happens when usb debugging is enabled.
Plugged in to an AC adapter though display goes to sleep.
This ROM from the start seems MUCH more "snappier" than the JK2 Eugene put out.
But, I'm still on the fence regarding Battery Life on JK6 vs JK2.
I am testing, but I noticed From a full charge then unplugged overnight (7hours) with only Gmail+Contacts Synching, I went from 100-89% using JK6. When I was using JK2 I went from 100-98% overnight.
Some of the cause could have been from some of the additional bloatware I found running in "Services" on JK6 for me, under Application in Settings, like Slacker Radio, so I will compare again tonight.
On another note, I've also been comparing using Power Tutor, which isn't for Galaxy S phones at the moment, but it does give a lot more detail than the stock Battery Usage app. I found that with the screen off on JK6, there is only a 3-7mw drain. On JK2, that was more like 25mw.
With the screen on lowest brightness, (auto-brightness off). I saw around 400-425mw on both. It's interesting to note that the light sensor draws about 100mw, according to Power Tutor...
Again, all this is up for discussion, especially since Power Tutor is not optimized for the Galaxy S...

Just plugged into USB with debugging enabled and the screen goes off after the 30 seconds that it is set to. Not sure what would cause it to stay on if that is what you are seeing.

There are still issues with Wifi Calling - I don't know about the battery drain piece, which a lot of people complain about, but The ringer still only rings on the earpiece, and not the main speaker , where a normal call would ring from. This makes it easy to miss a call, unless you're using vibrate.
Has anyone tested if the battery drain is better on JK6 with WiFi Calling?
I've made about 90 minutes of wi-fi calls today and a moderate amount of use of the phone display doing some other non-CPU intensive things.
59% after 6 hours of use.
Wi-Fi calling, other than the problem with the ringing, is working pretty good for me.
Battery use is a little bit better than stock JI6. It's not mind-boggling better, bit it is better.
My screen does not stay on while charging. I wish I had an option to do so. When I'm driving around So Cal I like to keep Google Maps up with my current location so I can monitor traffic problems, and there's no way to keep it constantly up on the display, or at least I haven't figured out how to do it yet. If anyone knows, let me know. I wish we still had the option to stay awake while on a charger.
There have been some posts by people which suggest this may be the final ROM. I'm pretty sure it's not. It's got some bugs here and there which I wouldn't expect to see on a final build, even from Samsung/T-Mobile. Nothing earth shattering, but enough to keep this from being the final release. That having been said, if you're currently running stock JI6, I see no reason why you shouldn't migrate to JK6. It's a definite improvement.

Interesting, I guess I'm just an exception
I love this rom, however, there are two things bugging me:
1) There is a slight lag in the app drawer when swiping left and right.
2) In Contacts, when you click on a name to call someone, there used to be the option to Call/Message someone. Now when you click on a contact, their contact card comes up with a big 'Message' button. While nothing horrible, it can be annoying.

Have you used Screebl before? I can't live without it.
My screen goes off too. It's dang annoying because I like to keep it on while I'm sitting at my desk using my pc.
If we can figure out why it still stays on for some people, maybe we could hack it into our phones? Is it a setting stored in a property file or a database somewhere?
My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?
turn off your mobile data when not in use. This will save tremendous amounts of battery.
if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.
I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.
I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~
Could be a Rogue app running killing your battery or radios not updated like stated above.
I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.
Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk
Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.
In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

I appreciate it. I really do. But that is exactly the things I'm saying are already off. GTalk is turned off immediately on my phone from the jump and latitude has never been opened. It's got to be radios. I guess I'm not really asking a question, I'm just telling the OP he isn't alone.

this is the thread with flashable .zips of alllll the radio updates ever out for the EVO.
http://forum.xda-developers.com/showthread.php?t=715485&highlight=radio
if you are having trouble after a radio update, just try some of these other radios and see if that helps
Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.
We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

Actually,
some android users looked at the posting date, saw that the op hasn't updated in over 24 hours, wanted to complain about it, decided against it, posted quickly the most useful idea they had.
All that while doing real science.
