Hi,
I'm posting this in return for all the information I found about the HD2 and poor battery performance. I read every thread I could find and every single post in them. I learned a lot and that allowed me to solve my problem.
I got no more than about 10 hours of use out of my battery with average use. Initially I thought this was the norm, reading a number of threads on this issue. I could however not believe that the performance was so poor, even taking the large screen into account.
I decided to try and determine exactly what it was that caused the battery to drain to quickly. I loaded BattLog and found it invaluable (see http://forum.xda-developers.com/showthread.php?t=444920).
I immediately noticed that my phone was drawing 85 mA even when it was in standby (or what I thought was standby). Based on what I was reading, the current draw should not be more than 5 mA while the phone is in standby.
I noticed in one of the threads that there were complaints about G-Profile causing battery drain. Since I had it on my phone I thought that might be a logical place to look. I uninstalled it a lo and behold... the current draw fell to below 5 mA when the phone was in standby!
In addition I loaded Bandswitch which switches off my 3G connection after it has not been used for 60 seconds.
Now I have about 48+ hours of battery life. When not using the phone a lot it extends to a lot more than 48 hours.
The long and short of it is that if you get poor battery performance, chances are it is because of some software that is installed on your phone.
Here are a couple of usefull things I have found in helping resolve my battery issues:
1) Use Batlog (http://forum.xda-developers.com/showthread.php?t=444920) to log the current your phone draws. If it draws more than 5 mA during standby you have a problem, most probably related to a piece of software on your phone
2) Your phone should not be drawing much more than about 150 mA when in 'active' mode with the screen at 40% brightness.
3) If you are running G-Profile, uninstall it and recheck your current draw. Chances are that it is the culprit.
4) Having an active data connection does draw power from the battery. In my case this is about an additional 130 mA. Load something like Bandswitch to disable the data connection when it is not needed.
I hope this information helps somebody. I realise that the situation is different for everybody out there because of all the variants such as age of the battery, sofware loaded and use. However, the reality is that the battery issues are most probably not because of a bad battery or the hardware but rather because of software on the phone.
BTW I am running:
OS Version: 5.2.21869
Manilla version: 2.5.19211619.0
ROM version: 1.48.421.2 (71294) WWE
Radio version: 2.05.51.05_2

Hi Gerhardvr,
What is the batlog software you used?
I'm very interested about your post.
Thanks.

Very useful findings, gerhardvr. Thanks!
found BattLog
ok, I found BattLog
It's just in showthread.php?t=444920
Have a nice day guys.

When I ran the Test, it said that I was using up 242mA in standby! I dont believe I have G-Profile installed, unless it was pre installed on the device. I have the latest versions of the ROM, Radio, Manila, and OS version, so I know the culprit cant be the ROM version... Any ideas? I bought this phone from T-Mobile US.... Sooo yeah
Folks, I've been trying to get to the bottom of this as well. I have a number of cab files which do seem to help a little. One of the bigest culprits I've found is the screen lockers. Disable them and see how you fair!

Soopahsteve,
I suggest you use Battlog to log to file. This is very useful as it will log the time stamp, the current temp of the battery and the current draw at the point in time. In addition it logs arious events on the phone, in particular the startup and shut down of applications, data connectivity, when you make or receive a call, whether you are talking or receiving on the call, etc. This can be opened in Excel and then analysed and if you are very lucky, you will pick up some patterns allowing you to link some programs to the battery drain.
However, the situation is typically slightly more complex to resolve since the culprit software are usually software that is loaded as TSR application at reboot. The result of this is that Battlog will not show the startup of these applications in the log file since they are already running at the time you are starting Battlog.
You should look at programs that manage phone profiles, screen lockers, screen calls or SMS messages, etc. In other words, any program that does work behind the scenes.
The reason you are seeing 242 mA in "standby" is because your phone is not really in standby. Although the screen is blank, something is preventing your phone from going into true standby, the processor is still active. The trick is to find what this is.
Sometimes the only approach is to uninstall the applications you suspect one by one and see if it makes a difference until you either find the culprit or can prove that none of the them are an issue. Then reinstall the ones you think are "safe" one by one and check whether the probelm pops up again. unfortunately you have to do the double sided approach because there could be more than one application that cuases your issue.
Painful I know but worh it when you have two days worth of battery time with some to spare.
Regards
See no reason to upgrade to the latest ROM

You know it. In reality I would love to upgrade to the latest and greatest but I've customised my phone to the Nth degree (did obviously not upgrade the ROM) by installing all the little apps I find useful, Cookies Home tab (best thing since sliced bread), etc. My phone is now just the way I like it.
It would take me quite some time to upgrade the ROM and to customise it again from scratch and I really don't see the benefit. I might be force to do it when I get to a stage where there are software that I would like to load that only works on the later ROMs but until such time I'm not gonna try to fix that that ain't broke.

is this the bandswitch u are using? if not, can i check where to get the program?

I just upgraded my ROM and did a Level 1 restore with Sprite Backup ... everything comes back except (I think) for wifi passwords.
i am drawing 180mA on standby..
im using custom rom, energy rom so thats very strange, but i have to agree that my battery life is terrible.. so i got to find a way to cut down on the 180mA drain..
I've always had good battery life on stock 1.66 rom losing 3% overnight with wifi and bluetooth turned off. Had to do a hard reset and started losing 15% overnight with the same everything. Did further resets and got nowhere. Ended up giving up on 1.66 although it had been fine previously after numerous hard resets - makes no sense but this is what happened. Just flashed to 1.72 and back to losing 3% overnight what it should be. And that is out of the box, to be honest all the battery saving registry tweaks are not worth the time installing and I leave 3G on all the time with updates coming through.
So it's all a bit random and shame on HTC for not sorting it out. My advice is do a hard reset, switch the wifi and bluetooth off and see in the morning if you have a reasonable battery life (or use the batt consumption program to verify standby consumption is sensible). Do this first before installing everything, getting frustrated and starting over again like I did when you discover that you're still experiencing high battery drain. This ensures that your starting point is a good flash and the phone is getting good life before adding any apps that could be causing a problem.
i have found my hd2 really does not like being in a poor or no coverage area. other phones i've owned have normally coped pretty well with no or very little signal. but not the hd2.
also noticed more drain in areas where there is only poor 3g coverage and its switching between 'g' and 'h' coverage.

Energy ROMs, just like the name goes, use a lot of Energy
They are baked in with a lot of performance tweaks so it's not unusual to get lower battery life per charge compared to other more down to earth vanilla ROMs.
Thanks for this thread, a lot of interesting information about the battery life of my HD2.
Just to mention: battconfig shows the power consumption directly in the task bar, a good way to find power guzzlers while they are active.
It's a pity we have no central place in this forum with a list of background applications that are known to drain the battery faster.
Or, also a needed information, a list of applications that are known not to do this (like PhoneAlarm, PocketShield).
I'm using the official rom only and have non fancy apps running or installed while I'm using the test bat program. As I speak the SD card is removed and celular radio is turned off.
Acording to program there is an indicator which is switching from -229ma to +78ma is that what its drawing of power?

Click to collapse
+78ma??? That must mean you are charging the battery. The best way to test current draw is when it is only on the battery.
I get about -5ma draw on standby and it tops out at around 180ma when I have the screen on, but usually hovers around 130 - 150ma. I have my screen brightness at the lowest setting possible.
@OP, I wanted to say this earlier... great topic, very insightful.
I have a few suggestions for everyone posting in this thread. Let's try and get some common data together that is more tangible in order to give us a more similar & common perspective for these discussions.
I suggest the following
1) Soft Reset. Once the device is on, do not run ANY applications. In fact don't do anything except for following the below instructions.
2) Turn your screen brightness all the way DOWN! (Turn off Auto Backlight and manually set it to the lowest setting)
3) Check your power settings and make sure that while your phone is on battery, that it is set to dim the backlight after 30 seconds and turn off after 1 minute
*** I have attached 2 REG files below for both Backlight and Power. Please use them instad of doing it manually.***
4) Turn off all the radios (Phone, Wi-Fi, Bluetooth). Let's make our first round of tests with the Radio's off. Radio ON complicates things a bit as there are several applications to keep track of that use the Data Connection. I'll come up with a more comphrehensive list later so we can do the Radio ON tests.
Screenshots
Use a program like Shave&Save and get the following screenshots
1) Use any Task manager and get a screenshot of all the processes running. Sometimes the number of processes displayed is longer than the screen size can accomodate. Take 2 screenshots in this case making sure that you capture all processes. Edit the image with MS Paint or some other Image Program and attach it here as one image. See the example in the post below this one.
2) Goto \Windows\Startup and get a screenshot of the folder contents
3) If you are using Sense, drag the slider all the way to the end (settings) and goto About Phone. Goto Software Information and get a screenshot of that.
Monitoring the Battery
1) Make sure your phone is not connected to the charger or to the computer.
2) Open BattLog (can be found here), set the refresh rate to 1 second and Start Logging.
3) After you start the logging process do not touch the screen / the phone again for exactly 2 minutes.
TIME THIS with a stop watch. As soon as the 2 minutes it complete, turn the phone back on and stop the logging.
Information to post here
1) All the screenshots from above.
2) The current draw (both on standby and while active). Also, please attach the file that logged all the information in this format: Forum ID - BattLog - dd-mmm-yy.txt
3) ROM - Whose ROM? Release Date? Does it have Cookie's Home Tab Installed or any other MAJOR Sense Modifications.

SAMPLE POST
HTC HD2 (T8585)
OS: WM 6.5
ROM: Energy * Build 21907 * Release 01.JULY.10 * CHT v1.8.5 - Dinik Edition
RADIO: 2.07.50.27_2
Current Draw (mA)
Idle: -3 to -7
Screen On (w/o Radios): -83 to -117
Those figures look normal to me. You should be getting about as good a battery life as a device like this can achieve.

I'll leave it to others to give advice on which radio to use. It might be worth installing danielherrero's (one of our own developers) bandswitch application http://www.commmgrpro.com/ You could use this to limit phone to certain bands only with an easy interface. Would allow you to check out exactly what is causing the drain on battery.
Mike
thanks for helps
Sorry, got me stumped. So with no radios on the consumption is double that when wifi is on!!
Let's see if anyone else has any suggestions.
Mike
infinite loop perhaps??
What ROM/Radio versions are you running? EDIT:: seen the ROMs, perhaps try updating to a newer dopod ROM??
Also what 3rd party apps have you got installed??
(RESCO was a ***** for doing this to my TyTN)
the exact same thing happens to me. i've charged it completely, it obviously got really hot. usually at this point, i would take out the battery and let it cool off before turning the phone on, otherwise it would get even hotter and eat 300+ mA and drain the battery fast. this time i opened the wi-fi connection and immediately the battery status dropped from 332 mA to 130, and stayed down there. the phone even cooled down a bit. after i've turned off the wi-fi, it started draining and heating again. what can i do? is it a software or hardware problem? i'm using schaps 4.31, 1.47.30.10, have google maps, palringo, opera, tcpmp installed
I have the same behavior, too.
But not yesterday evening. After restarted it for the xxx time it staid at 28mA. This was so until I left the train in the morning. It went up to 347mA and I am not able to get it back to 28.
I am using the default HTC ROM "HTC_TyTN_GER_3.54.257.2_103_6275_1.47.00.10_108".
I also tried several other ROMS (Schaps, Pays ...) and different radio versions as "HERM_Radinly_1.16.00.00_CustomRUU", "HERM_Radinly_1.47.00.00_CustomRUU", "HERM_Radinly_1.47.00.10_CustomRUU", "HERM_Radinly_1.47.30.10_CustomRUU" and "HERM_Radinly_1.54.30.10_CustomRUU"
but none of them helped me out.
I also done the Exchange Server trick, deactivated 3G and even deactivated all GPRS or EDGE possibilities from provider side.

Phone gets hot
Hi,
I am not an expert but I had the same problem with my phone, I solved the problem by moving some software I had on my storage card to the internal memory, (in my case it was the encryption and additional language support software I had)
Another way is to look for the Power management tweak in this forum which helps to manage your storage cards power draining,
Sound strange but it worked for me.
Good luck
Hi,
the new battery has arrived.
There is no change in battery draining
What I recognized is, that if the battery is "cold" the power consumtion is around 28mA. But after a call it is getting warm and uses 10 time so much of power.
Please don't laugh now:
I put the battery inside my freezer for 5 minutes. Put it back inside the mobile ...
... 28mA.
If I keep it cold it stays fine for 3 days.
There must be any solution on that.

Hi, I'm new in this forum, and I don't speack English well, so I want to excuse me!
I have the new Touch HD, at the beginning I changed immediately the original ROM with a new one, I installed a lot of programs, and everything woked very well for two weeks, but then I had a big problems with battery...a the first the battery was very good, -10/15% per day, but suddenly after two weeks the battery lose 1% of its charge every 2/5 mintes...if I disconnect the power when the battery is 100%, after one hour without use (and also without wifi, BT and GPS), I have 70% of charge!
I try to change the ROM, a friend suggested me a new upgrade for Radio, but I didn't resolve my problem!
Now I buy a new battery online in htcstore, but if I put my mobile in "Fly mode" the battery work very very good!
I want to say that here normally I have the signal indicator with 2/3 nicks, so the signal is good!
Someone can help me?...someone have my same problem?
Thank you so much fo everything!
Greetings, Eddy
the battery will be used up quickly if your fone is constantly searching in and out for a 3g signal, regardless of 2g signal strength
have you got wifi on?
bluetooth?
a gps app running?
what other apps do you have running in background? some really poll the cpu a lot and will lead to battery drain
other than a dodgy battery, it must be some software running that is using up the battery
Thank you for aswering!
In background normally I have SMS o Contacs, but also if I close every programs in background the battery doesn't work well!
No, Bluetooth is OFF, GPS and WI-FI are OFF, I use telephone just with gsm!
Also when I write message, normally I write a message so long (3/4 messages), after wirting, the battery lost 10%, and I didn't have this problems at the biginning!
I left my mobile on also during the night, and in the morning I had again 100% of charge...now 100% it's a far dream!
try turning off the autoadjust for the screen and setting it at a medium setting, also make sure the backlight turns off after a minute or less.
its a huge screen and will burn up power, although saying that i watched a full length film on my HD the other day and only used 20% in 1.5hrs
if no progs are running in the background and its not a display issue (how have you checked whats running btw? need more than just WM taskmanager, try mem maid or similar) and the problem is not there when in flight mode. then i can only assume its the rom you are using, try another with a different radio rom in it
i found roms with 1.10 radio to be better than 1.09. try this rom (mulitlanguage) works good for me
http://forum.xda-developers.com/showthread.php?t=465637
edit: have you got HDTweak installed? its good to configure the data to auto turnoff after 1 minute or so (even in gsm gprs could be running)
I tried to setup the new ROM but I didn't resolve the problem!
If I leave my mobile only with GSM on, without use it, without call and sms, the battery lost 2% in 30 minutes, and it's not normal!
If I use it, change settings, write message, the battery lose 5% in five minutes!
I don't know what I have to do...this mobilie now can't live without a power connection!
I want say also that at the beginning some application in my HTC wanted "HTCAPI.dll" because they didn't found into the mobile...so I found this dll online and I did copy/paste into the directory!
It can gave me problems with battery?....I don't know how it's possible, but I don't know!
Try to buy or borrow another HD battery and compare them. You should know the problem then.
Of course, I alredy bought it online, and I'm waiting to get the shipping!
But it's very strange that a battery stop to work suddenly, but I know that there are a lot of people who have my same problem!
If i were you, i would flash back the original rom and do a hard reset. Then, without installing anything on the device, see if the problem persists.
Thank you ardsar...I want to try....can you tell me, what I have to do to obtain the original product?...without hardspl and new rom?...like the first time that I turned on this HD! Thank you so much!
For example, I have your same SPL and ROM at the moment!
Hi Ardsar, I flashed my ROM and SPL (brand), and now my mobile is like the original but....do you know Teeter?...I played 2 minutes, I completed 3 levels, and from 85% the battery is now at 79%...
Hi guys...yesterday I did a lot ot tests, but without positive results, but I fund out new problems:
1)The bettery lose a lot of charge also if my Blackstone is offline, when I use it with TouchFLO, Teeter, SMS, Settings...everytime!
2)I have near to icon of signal, the simbol of GPRS, but sometimes it changes with the simbol H and with this new symbol, the signal falls and to resolve it, I have to wait a long ore reset the mobile.
Now I'm not sure that the "target" is the battery...I don't know, I changed also the Radio ROM with new last, but the problem is not over!
Before put it into garbage case, someone can suggest me something to try?
...I will never bring it to Assistence HTC, because I will have to wait some months, and I didn't pay 500€ to have it "under repairing"
Do you have SK Tools 4.4.6 or another battery monitor installed?
With SK Tools, you can see under the sys info the current battery use. My usage is in standby with lighted display -100mA. What's normal?
My battery is also very empty. Last evening i had 54%. This morning, the phone was off, no power any more.
No, now I will try this tool!
But I think that you also have problem with battery, becase the firsts days that I had my HD, I left my mobile on the whole night with 100% and in the morning I had 100%...I had 99% at lunch time!And a lot of friends that have this mobile have the battery so strong, like me at the beginning...so...I'm getting angry
i have this problem too. had my HD for 2 weeks coming to 3 now and my battery seems to deplect very fast, totally different when i had it. could be becoz of the wallpaper and 3rd party theme i had
For me, it seems it's a software or anything else that needs so much battery power, perhaps the hotfixes or something else.
Sadly, the whole battery monitor progs don't show the needed power per running process, only the current usage. Can anyone with a "good" battery life cann post his current usage? (For expample with SK Tools System Information/battery supply)
Is the backup battery always at 0%?
Battlog
How about this. You can log your activities and see how much battery current (discharge) each application is using by the ma figure. It produces a .log file but if you change it to .txt you can open it up in a text editor.
Hope it helps.
EDIT: Just found out there is better info on it here on XDA Raphael forum. Credits to PalladiumTD for this app.
Today I tried a new battery, and also with a good battery, I have the same problem...so I think that I have to send my mobile to HTC service and ask for a new one, because it can be an internal problem, maybe of motherboard, radio, or I don't know...but it's sure that is hardware problem!
Did you a hard reset and installed nothing else?
Yes, I did...I alredy unpacked it and monday I will send it to HTC service....I hope that they will sed me a new one....a friend said to me that maybe this problem for them is called DOA (dead on arrived) and in this case they have just to change it!I hope so!....but I don't like...!
I know that I can reset it pushing the volume control ecc.....someone knows it exactly?Thank you!
I've been looking around for a long time but I haven't found a way to overcome the hell-like battery drain.
I tried to delete MMtaskmanager from windows/startup, I tried to flash different customized roms, but it doesn't seem that the problem is getting better.
Now I'm with RomeOS ROM 4.05, HSPL 2.08. Battery drain is horrible.
Someone said it might be a problem of HSPL2, but I don't think there is another version of HSPL for 1024LEO available.
May I have any ideas from someone here?
Thanks in advance.
The HSPL is just a bootloader, so I can't see that being the issue. Here is what I did:
- Go into \Windows\StartUp and delete "MMTaskManagerhook.lnk" - this is a big savings according to NRG (reboot)
- Turn off your auto "weather" and "stock market" refresh
- Go into Start > Tools > "Device Lock" (present in the NRG ROMs) and uncheck "enabled" and "lock if playing music"
- Turn down your screen's brightness and/or put on "automatically adjust backlight" (this is a huge savings as well)
Using the "tBattery" app located in Start > Tools > tBattery, my temperature is around 26' C and the draw is around -150 to -160. At idle (suspend), it is around -4 to -5.
It has also been said that the "Document Indexing" service and the .mp3 indexing service can cause quick battery drain if you have a lot of documents and/or if you have a corrupt .mp3.
You can turn those off as well, but an easier way would be to remove your MicroSD card and see if the battery drains slower. If that is the case, then you have an issue with or on your MicroSD card.

Using the "tBattery" app located in Start > Tools > tBattery, my temperature is around 26' C and the draw is around -150 to -160. At idle (suspend), it is around -4 to -5.
It has also been said that the "Document Indexing" service and the .mp3 indexing service can cause quick battery drain if you have a lot of documents and/or if you have a corrupt .mp3.
You can turn those off as well, but an easier way would be to remove your MicroSD card and see if the battery drains slower. If that is the case, then you have an issue with or on your MicroSD card.

Thanks for your reply. I'll try to remove MicroSD card and see if the problem still exists. Will report here.

I dunno if it is in the MaxManila version, but it is present in the CookieMonster version.
Take a look in TaskManager and see if you have the MMTaskManagerhook.exe running.
Thanks for the tip. I'm giving this a go right now.
FYI, I'm experiencing battery drain on Energy. I've been reading that this is an issue with lots of roms.

I've been looking around for a long time but I haven't found a way to overcome the hell-like battery drain.
I tried to delete MMtaskmanager from windows/startup, I tried to flash different customized roms, but it doesn't seem that the problem is getting better.
Now I'm with RomeOS ROM 4.05, HSPL 2.08. Battery drain is horrible.
Someone said it might be a problem of HSPL2, but I don't think there is another version of HSPL for 1024LEO available.
May I have any ideas from someone here?
Thanks in advance.

Hello,
I am new to this phone, but not new to flashing and other things with HTC phones. One thing that I have always noticed with them is their battery life is horrible, and as the screens get bigger and more data intensive things are going on, the battery life is not going to be great.
How much time are you getting, a few hours, a day, half a day? Depending on usage and such, don't expect anything more than a day.
Also, if you can do the things that are noted, it will help significantly.
I have the stock rom and the battery life is horrible... worse than my n900 which sucks...
I read everywhere online how great the htc hd2 battery is.. 52hrs of up time? with mild use.. I get less than 10 with mild use.. and only 2-3 with heavy use..
I have had many phones this past year and so far this is by far the worse..
I have made my email update less.. turned off all auto updates as well..
I don't have many apps installed and have reset the device once already.
Screen brightness is set to auto..
Any ideas?

Thanks for your reply. I just sold my HD. I remember my HD could go 1.5 days the same usage as my HD2. But HD2 could only make around 6hrs. I'm sure there is something wrong with the battery system oh HD2.

Hi, is any one here so nice to give a link to tbattery0.56? tbattery0.6 does not work on HD2, it will give out weird and huge numbers....I'm defeated by the battery, frustrating..
For me, the battery drain is all about the screen. The radios are actually pretty efficient. I've got weather/twitter/stock updating frequently (30/30/5 mins), and two push email services humming along (exchange/hotmail), and the phone barely sucks any battery if its just hanging out on my desk, pulling from data every few minutes. Talk time appears pretty good, too.
When my battery disappears absurdly fast is when I'm using the screen. Text messaging, web browsing, emailing....even light-moderate usage here sucks it down fast.
Other than turning down your brightness, I don't know what you can really do about that one. As screens get bigger, but batteries don't (in fact, my Palm Treo 755 had an 1800 mAh battery, Droid 1400, HD2 1230), battery life is going to suffer.

this was, in fact, my biggest concern. Big screen means more power. All the reviews I've read indicated I should be getting better than I have been, which is bothersome. I'm tempted to revert to a stock rom and give it a go.

The current seems about right in all honesty. Even though you *think* that it is idle, there is stuff going on behind the scenes (your screen, for example, takes up A LOT of power).
Go ahead and load up 0.5x or whatever and see if you get anything different.

Yes. You are right. I was just going to update, with microSD inserted and compass program running and tbattery running, the current is around -222. Now I stopped all the running programs in task manager, current seems to be -162.

Miri's Elegant ROM TMO_US HD2
Using the ROM in the image below. Installed it with 64% at around 1pm today 03/29 and so far am still at 65% and thats with at least 30mins phone call, some web browsing and quiet a few text messages. tried the other ROMs for tmo_us and this MIRI ELEGANt is working out great for me. downloaded it at htcpedia.com
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.
Thought I'd just share this. I had been stuck with this issue for a while; basically needing to fully recharge twice a day. I tried a lot of things recommended on here and elsewhere; all of them either made minor differences, none at all, and some made things worse. Things in that category are wifi, 3g, bluetooth, gps, setcpu, task-killers, screen-dimming, resetting battery stats, starting Haret with the key lights on, etc. All these things can potentially make a difference, but didn't help much. Plus, most of them involve de-smart-ing a smartphone, and what's the point of that? I tried changing SD card, as I have a 16GB Transend class 6 card which I believe draws a few more mW than e.g. Sandisk cards, and that didn't really help either.
As an indicative measure, I could charge to 100% (and green LED) at 11pm, put the phone into Airplane mode (GPS off as well), kill all tasks that are not needed, go to bed, and by 7am the battery was on around 50%. So that's with NO comms, NO screen, nothing. Android battery use showed most of this usage was the screen. Er, no. I installed CurrentWidgit (from App Market) and got it to log; during this overnight lack of activity it averaged around 65mW, and was never below 60mW.
So after all that rambling, the answer is: radio ROM version. When I installed Android, I installed the latest radio ROM available at the time (still the latest I think); i.e. 2.15.50.14, from http://forum.xda-developers.com/showthread.php?t=611787. After pulling my hair out trying all the above, I flashed the radio ROM with 2.12.50.02_2, and as if by magic, current draw under similar conditions to above is about 7mW; i.e. 10% of what it was, and an overnight period as above goes from 100% to 96%. Much better
I should point out a few extra things:
a) I arbitrarily chose that radio version. I don't really have time to try them all, so if anyone cares to test and post here, perhaps another version gets even better results. To make them meaningfully comparable, install CurrentWidget, get it to log every minute, put the phone into airplane mode, GPS off, kill any obvious large apps like Maps, camera, email polling, and don't run any "battery-saver"-category apps (I had just Messaging, Google Services and Android Keyboard under Settings > Applications > Running Services), turn the screen off for a few minutes (don't move the phone either), then turn it back on and look at the CurrentWidget log. If you post your results here, include which network you're on.
b) This "secret" is sort-of hidden in a few other threads about this, but only in passing and not really prominent. I thought it deserved its own thread so people can find it a little quicker.
c) I don't know if there are other dependencies at play here; e.g. perhaps 2.12.50.2_2 is best with O2 (which is who I'm with), and maybe others are better with other networks. I don't know enough about radio ROMs to know. If people post their results with their network we might figure it out.
d) Changing radio seemed to also cure another problem I was having, namely the data connection on both 2G and 3G regularly disappearing, even though I had a 2G/3G signal. (I used to fix this by switching between 2 virtually identical APNs, while cursing and muttering...)
e) I'm using AmericAndroid GB233 CyanogenMod7 on SD.
Very usefull info indeed! i use the latest radio too and i face the same battery issues. I've tried all kind of stuff (task killers etc) but with no luck, mb i"ll try a couple of radio vers. hope yours doesn't carry any robo voice incidents (I use the CoreDroid v0.8 one)
Stop using SD, flash android directly to your nand, my battery according to Battery Diviner, lasts 25hrs with a full charge not on airplane mode. I used to do SD but I got tired of the slowness and huge battery drain, NAND is the way to go.
I am thinking of going NAND now, but it wasn't really an option while I might have needed to go back to WM just to make it through a single day without access to a charger. What radio version are you using?
But if radio version is the key, i see no point why we should abandon the sd option & move to the nand one. And the 25h -no charge- nand duration isn't such a big deal, is it ?
I have to version 2.15 and I am on nand.... my battery drain is around 3-5ma standby.... which I think is pretty good.... so I think nand is the key..... not radio
Sent from my HTC HD2 using XDA App
It would be interesting if you now flashed to 2.15 again and record your consumption, you might find the early high consumption is not repeated, your original radio may have been very slighty corrupt? I'm using AmericAndroid on SD and get 3mA drain in standby with radio 2.15.50.14, battery widget predicts 12hrs use with 3g phone on and fairly frequent use or 4 days in standby (doubt I'll ever test that one but the 12hrs is about right).
My only temptation to go for NAND is speed, SD is very slow unless using a RAM build and there are too few of those. Can't quite leave WinMo just yet so sticking with RAM on SD.
Yea... even I'm curious... flash back to 2.15 and let us know your results..
Sent from my HTC HD2 using XDA App
I have also the 2.12 radio since january with different NAND roms (mostly sense) and had always 3-5mA in standby. WIFI and 3G off, GPS On/Off makes no difference. Had never the robot voice problems at the first call and no other problems that 2.15 users not have.
There was already a thread where some android nand users confirm the better battery life of 2.12, but not such a big difference like in your case.
Have found a similar thread of WP7 users with the same results.
Any sd android users around with positive battery results? my battery gets raped in almost 15h with normal use! And yeah my stock winmo 6.5 rom does pretty well, while my Leo stays alive & kickin for about 4 days. And just to get a bit off topic, neither Froyo/Gingerbread got me crazy as an OS, nor the "old ship" winmo 6.5 can keep anyone excited anymore. I hope Honeycomb port will be developed in a stable well working level for our Leos.
I think part of the issue here is different peoples' expectations are different. If you are already getting say 12-24+ hours with ANY type of usage, you are probably in a different category to the one I was addressing. The issue I was addressing in my OP is getting extremely poor battery life, of the order of perhaps 6-8 hours with light usage. Several people seem to experience this; i.e. charging required 2 or 3 times a day.
The WM thread mentioned a few posts back is interesting, as there seems to be a clear trend of 2.12 giving better battery life over 2.15 (some anomalies though - be nice if someone who really knows these things intimately could suggest what the dependencies might be).
When I have some time I'll try flashing a few different radios and measuring in an at-least semi-scientific manner. When I have a little more time I'll try NAND with different radios as well. (Anyone with time feel free to go ahead and post results in the meanwhile though!)
nand that killed battery life
I have been using nand roms for a few months now, ever since mdeejay blessed us with his gingerbread builds.
presently using ginger-honeycomb theme rom.
Battery has to be charged twice a day with minimal usage. 2 hours of kindle/music is enough to fry the battery. radio is 2.15.
the rom is superb in appearance and functionality but battery is a real eyesore.
suggestions appreciated.
@fx.dcny: have you tried 2.12 radio as I suggest in my OP?
Hi All,
I'm using Radio 2.15.50.14 and when I use WinMo (ROM Elegancia 2.0), my battery lasts longer than 24h, with a few phone calls and mails and sometimes use of GPS.
With Android on SD, I must charge my battery 2 or 3 times a day. Even in Airplane mode, drain is very high (losts 40-50% overnight). I'm currently with Rafdroid HD 4.2 SD build, but things are same with all other Android SD builds I've tried.
I've just installed current widget, and drain is 60 mA in standby, which seems very high ! and I frequently kill apps with Advanced Tasks Killer (apps like Maps, Soundhound that always reappear !) but maybe this Task Killer makes more bad that good...
As suggested by the OP (thanks for the tip!), I'll tried another radio when I have some time, I still have a backup of radio 2.10.50.28_2, and report to you...
Do someone know how to find the culprit app from Current Widget log? I just see a long list of running apps, but no clue about which one(s) is/are eating the battery.
@thivi: my experience was that the apps listed by CurrentWidget were not helpful (in this context), and like I say when I was getting ~50% battery loss in airplane mode overnight there were no unnecessary apps running, and Android was reporting the majority of the battery use as "Display". Something else must be happening under the radar of the various battery monitors (both native Android and not). I'm guessing (only guessing at this stage) that something in the radio ROM code causes it to draw more current.
Hi folks, this is a first post for me but battery use seems to be a never-ending holy grail to Android users!! I have a HD2 running HyperDroid CM7 V2.0 Fearless Falcon on NAND with radio 2.15.50.14. The phone is a branded TM UK handset and have to say that the biggest battery-eater I ever met was Google Maps. Once uninstalled (installed it on first setup), and with carefull widget management, I can just get 3 days between charges. I must point out though that I am not a heavy data user or anything, I just like to have a good functional handset that I know will do everything I need effortlesly. The HD2 is just the thing. Just as an edit, with Google maps being installed, even if force closed, I only ever got 6 to 8 hours from my battery.
I have found this out from master rom thread. Most of the build recommend 15 but i recommend 2.12.50.02_2 if you have battery drain issue on standby.

After pulling my hair out trying all the above, I flashed the radio ROM with 2.12.50.02_2, and as if by magic, current draw under similar conditions to above is about 7mW; i.e. 10% of what it was, and an overnight period as above goes from 100% to 96%. Much better
I should point out a few extra things:
a) I arbitrarily chose that radio version. I don't really have time to try them all, so if anyone cares to test and post here, perhaps another version gets even better results. To make them meaningfully comparable, install CurrentWidget, get it to log every minute, put the phone into airplane mode, GPS off, kill any obvious large apps like Maps, camera, email polling, and don't run any "battery-saver"-category apps (I had just Messaging, Google Services and Android Keyboard under Settings > Applications > Running Services), turn the screen off for a few minutes (don't move the phone either), then turn it back on and look at the CurrentWidget log. If you post your results here, include which network you're on.
b) This "secret" is sort-of hidden in a few other threads about this, but only in passing and not really prominent. I thought it deserved its own thread so people can find it a little quicker.
c) I don't know if there are other dependencies at play here; e.g. perhaps 2.12.50.2_2 is best with O2 (which is who I'm with), and maybe others are better with other networks. I don't know enough about radio ROMs to know. If people post their results with their network we might figure it out.
d) Changing radio seemed to also cure another problem I was having, namely the data connection on both 2G and 3G regularly disappearing, even though I had a 2G/3G signal. (I used to fix this by switching between 2 virtually identical APNs, while cursing and muttering...)
e) I'm using AmericAndroid GB233 CyanogenMod7 on SD.

sellotape, you're the boss !
now with radio 2.12.50.02_2 I have 4-7 mA drain in standby instead of 62-66 with radio 2.15.50.14... And last night I only lost 7% battery (and I was not in Airplane mode), it was 40-50% with radio 2.15.50.14 (and in Airplane mode !)
So this radio 2.15.50.14 seems to be the culprit for high battery drainage in Android, at least for some users...
I was happy with the RAFDROID HD 4.2 build but had 2 problems : 1.high battery drainage which is now solved thanks to sellotape thread, and 2.heavy lags that were caused by my SD-Card, problem detected thanks to this thread :

so now I'm enjoying a very fine Android experience with my HD2, even with a SD build
@GPZ550: it's true that Google Maps is almost always in memory, even after killing it. But I'm a heavy user of it so I don't want to desinstall it. And with radio 2.12.50.02_2 it seems that I can have a decent battery life even with google Maps installed.
I don't want to add confusion here, but my experience as in the OP came to an end about 2 days ago, for reasons I couldn't really associate with anything in particular, except *perhaps* an app update from the market. So... what I did is flashed 2.15 again (to at the same time answer boomboomer and fahd_freak's questions), and I am now back to <10mA standby (down from ~60). I suspect if I'd flashed 2.12 again it would also have fixed it, but I'm out of experimental options in that direction for now. This leaves me rather confused. I would have thought that apps (even under SU) would almost certainly not have sufficient access to alter the Radio ROM.
As a dev myself I struggle with the idea of the ROM becoming "a bit corrupt". I would have thought *any* corruption would have been fairly catastrophic. And yet, mysteriously, re-flashing the ROM seems to be an answer (for now). Perhaps there is some state data that the Radio ROM stores that gets corrupted or invalid and this is overwritten with a re-flash?
Personally I'm not too fussed if I have to reflash the ROM every month or so for now, ridiculous as I find it in principle. It does perhaps mean it's not just radio version that's at issue, but perhaps the action of flashing itself.
I managed to get 5mA draw in standby mode on the NexusHD2 for SD builds (3G on but GPS and Wifi off), with some spikes (when data is being pushed). Able to last a whole day with moderate usage. (Radio version in my sig.)
But really, the NAND builds are much better overall. I managed to get a very similar battery usage pattern as above with the latest NexusHD2 Gingerbread ROM V2.7, 3G, GPS and Wifi all on.
