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

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.
Was getting several data freezes every day (5 to 7 every day). I installed a free app from the Android Market called DATA ON DEMAND which is supposed to switch your data from 3G to 2G in order to conserve battery when phone is idle in sleep mode (screen off). This app did not work on my device. It would kill the data completely after phone was put to sleep and data nor voice would restore unless the phone was restarted. Needless to say, I uninstalled the app and rebooted my phone and strangely, my phone has not dropped data even ONCE in 5 DAYS. I have tested this on 3 other HD2's and all followed the same pattern. I have only tested them for the last 3 days though. My exact setup as far as OS's is:
Windows Mobile Rom: Omega v14 WWE XT CHT
Radio: 2.14.50.04
Android Rom: mattcevoleo1.0.1
Kernel: [email protected] (r1)
Please post if this works for you if you decide to try it. I am curious. That was probably the only real downside to my daily HD2/Android usage.
When you say data freeze, do you mean the issue with the up data arrow getting stuck?.
my build too i am using mattc 1.8 with sense and when data is on the arrow stops and i lose data happen to me 5 time a day

Same here, I've also noticed the phone uses a lot more battery power when the data connection is on. Maybe its linked?
Thanks to the OP for the possible solution.

Since updating to hastrian 7.1 I don't see any improvements to my battery life and data like everyone is taking about is still a problem, if some one could correct this it would be three best setup ever
It not solve my data connexion problem, i have installed the apps, set it to AUTO, reboot, delete the apps, and now everything is same than before i install the apps... nothing better...
using the Mdeejay eVo Sense v. 1.0 Warm|3.29.651.5|[kernel: hastarin R7.1] release with the libhtc_ril_wrapper.zip updated (9/28)
Ill try this on my 1.8 and my evo 1.0.1, will report back

How long were you running michy's r1 kernal before you installed that app? Reason I asked is because installing michy's r1 kernal and rebooting is what solved my data issue.

I concur. Thats why I was wondering how long had he used that set up before downloading the app. I have almost the same exact set up and my data connectivity has been excellent (this is without downloading that app)
I can confirm this has worked for me, after updating my kernel to hastarin 7.1
i started having data disconnections, then this came along
thanks for sharing
My attempt ...
Until now, any build that uses PPP would not work without at least one flaw in the data connection every half hour or less... Terrible...
I then decided to try a combination of the tips that I've been reading in the forum.
First, I edited the build.prop in system folder and changed the last two lines in the file, the primary and secondary DSN. I used Namebench, a free program to find the indication of which DNSuse for my region (I live in northern Brazil). I run the Namebench on my laptop and copied the two recommended DNS addresses.
Then followed another tip, and using the *#*#4636#*#*, changed the network configuration for GSM auto.
And finally, in the phone settings, I changed from GSM/WCDMA auto to GSM only...
It's five hours straight without any disconnection !!!!!! It is true that the connection is slower because of GSM, but it is steady and reliable!
My next step will be to change this last parameter for WCDMA Only and just see what happens
Sorry about my English, hope you can understand!

+1. Had freq. dropouts when on 2.09 radio, 2.10 caused the entire radio to dropout and 2.11 was fairly stable but still freq. dropout. 2.14 was been the most stable radio for me so far, only 2-3 dropouts max per day.
Of course, the early radio dropouts could've been caused by the older buggy ril wrapper library, so I might revert back just to experiment around a bit more.
Using Mdeejay Evo Sense 2.4.2 I Managed to resolve my data drops... at least in the last 24 hours.
I still haven't gotten one freeze on any of the 3 phones I'm testing since I did this. maybe I'm lucky...

Ok. Just to give a feed back...
With GSM only, no drops at all!!!!
When I changed to WCDMA only, overall it's more stable than before, but I had a few drops last night and this mornig...
So, for me, I'm switching back to GSM only. I do prefer a more slower connection but with no drops !!!
I'm using 2.14 radio, with FroyoStoneSense v3.1 (Darkstone) !
Hi guys. I'm testing this for some days and i always get same problem:
All no Sense build i have tested drains my battery with BT activated really quick. A quick log:
Code:
Everything off, less phone connection
2010/11/16 23:35:03,-63mA,61% <- BT on
2010/11/16 23:36:03,-63mA,61%

2010/11/16 23:47:04,-63mA,60%
2010/11/16 23:48:04,-64mA,60%
2010/11/16 23:49:04,-63mA,60%
2010/11/16 23:58:27,[COLOR="SeaGreen"]-5mA[/COLOR],60% <- BT off
2010/11/16 23:59:33,[COLOR="SeaGreen"]-5mA[/COLOR],59%
2010/11/17 00:01:00,-8mA,59% <- Wifi on
2010/11/17 00:02:43,-8mA,59%
2010/11/17 00:09:59,-7mA,59% <- Wifi off
2010/11/17 00:13:57,-5mA,59%
Even with Wifi on i get much better energy consuption than with BT.
Nevertheless i get a good result with most Sense builds i have tested. Not sure the reason. Maybe Sense drivers for BT are more optimized?
I'd be thankful any help with this, i love Android builds without Sense, and i'd like use them but i need BT ON working without a big energy drain.
Thanks in advance (and sorry for my english)
Nobody has a high battery drain with BT on using a build without Sense? i can't believe it...
I do, but turning the Bluetooth off and on again, it'll solve the issue for a while.
It's drained my battery numerous times during the night... Thankfully I use another alarm clock.
Hi and thanks for the report. Maybe your battery drain in the night is due to automatic sync with gmail. You can try to disable all data connections during the night to check if is this the reason. As far as i know sync uses to check frequently changes in gmail to update...
Thanks for the report m8

BT Battery Drain
I still have this problem. It seems they never resolved it, but for some reason I don't see many people complaining about it.
I get 65mA with BT on in standby. It occurs in both MDJs kernels and Hastarin's and all variants of Hastarins.
Hi there,
I'm using this - http://forum.xda-developers.com/showthread.php?t=917590 - and also have 60+ mA with BT on (but nothing connected).
Does anyone know a fix / patch that can be applied to the system?
Or perhaps this issue can only be fixed while cooking the build?
I love that Android version but the battery drainage just kills the joy.
All the best.
yeagh me too,also i would like to know how did u see thoose logs of battery drain?

How are you measuring the battery usage? Is this with just the ROM, or have you installed any apps?
Any ROM will consume a bit after the first boot, and will settle to 1 - 5 mA eventually unless something is wrong.
I have installed Current widget from the market.....

there's quite a few threads on "battery drain" in HD2 / Android forum, right now cannot provide you with links but you'll definitely find sth, via forum browsing, search or google in xda,
afair one of the chief reasons was GPS location turned on, also some ROM used to have problems with BT in standby, for starters disable all sync / comm / location functions, then check the current and if it's ok start turning them one by one, with a few minutes of standby in between
Battery solved, Black Screen
OK, thank you for your help. I manage to get power consumtion of 6mA in st-by eith "Transformers" version of android from this forum but now i have problems with wakeing up my phone. I will ask here to avoid opening new thread. When My phone goes to sleep it happens that i can't wake-up him. Lights on buttons get light, but screen remain black. Only solution is to remove the battery. My Phone info is as follows:
HTC HD2 T-Mobile
OS version: 5.2.21892
Manila version: 2.5.20121412.2
ROM Version: 2.13.531.1
ROM Date: 4/28/10
Radio: 2.10.50.26
SD Card is ScanDisk 2 16GB
Thank you for help and patience...
Does somebody knows the answer to my problem, please....

don't know which build you're using, mine is ACA (SD), in some of the older builds sth similar used to happen, but usually most of the SOD's were shallow, so I was able to get out of them waiting 5-10 seconds between each attempt of unlocking the device, either using power button, of home/menu combo,
what helped for some users was setting the min CPU in Set CPU or CM Settings up from 128 to 245
When I was using SD based builds I have problems with battery drain as well. To solve the problem, power off your phone, power it on while holding the vol. down button, then pull batt and turn it on again. Then boot into Android through Haret. It worked for me, but it got irritating when I had to do that quite often. In the end I just switched to NAND builds, and I never had problems with battery drain since.
O and just btw cyberx85, I think normally we use a 2.15.xxx radio for the HD2. You can try these links on how to get that on your HD2.

I will try that.... Thanks
Hey guys,
I have had this 7.5 build for a while now and everything seemed fine to begin with. But now, within the last 3months or so, when ever I try to make a call, either 1) the phone freezes 2)the phone restarts itself straight away or 3)the call starts but I cant hear anything or see on the screen so I have to restart.
The battery also doesnt last more than 7-8 hours?! with all data settings, wifi, 3G off, brightness at the lowest, battery saver onand I even turn my phone off in the underground!
As a result I have to charge my phone to at least 60%-70% by 11pm otherwise my alarm work go off for work in the morning!
I am using the same radio version that came with the ROM, here are the details:
HTC schubert 7.5 build (os version 7.10.7740.16)
Radio software: 5.71.09.02a_22.51.50.21U
Radio hardware version: A.102.0.D4
Firmware revision: 2250.09.07491.605
Hardware revision: 0002
I have seen some questions about the various combinations of radio and builds? but I am wondering why it freezes still Is it a problem with the phone internals more than software maybe?
Thanks for your help,
Marc
freeze, restarts and speed problems is related to incompatible sdcard
for better battery time you must use radio combination 2.15/5.51 or 2.12/5.51 with camera trick (you have 5.71... this is battery draining radio)
all this explained countless times on forum
