UPDATE Dec 9:
ALL i did was use Autoboot (Exceller Multiple Build Loader) set at 3 seconds
Try this setup if all else fails
Rom: ChuckyRom Lite HERE
Radio: 2.15.50.14 HERE
Droid: HyperDroid 1.7 HERE
AutoBoot: Exceller Multiple Build Loader for Android/Ubuntu HERE (Comes preinstalled in ChuckyRom)
PLEASE KEEP LEAVING RESULTS AS I TRY THEM, AND CAN UPDATE THE FIRST POST
10/25:
I have been reading and in a recent post I read HAVE THE BUTTON LIGHTS ON WHEN U BOOT ANDROID and u will save battery and its true try this!
AGAIN, PRESS A BUTTON IN WM AND HAVE THE KEYPAD LIGHTS ON.
THEN AS QUICKLY AS POSSIBLE BOOT ANDROID.
I AM CURRENTLY GETTING 3MA WITH SETCPU
I had to try this twice before it worked but THE KEY IS TO BOOT ANDROID AS SOON AS THE KEYPAD LIGHYS TURN ON!

I just posted this in another battery thread but I think the real key is booting Android as quickly as possible and not really the lights so much as I have achieved similar results just using Exceller Multiple Build Loader app and not even touching the keys/lights. C/P from the other thread-->
Tried different techniques to get better battery and found that even on the same build with exact same setup would give varying results. Here's my setup that I would like others to try and post their results. SetCpu with screen off profile set to 245min/max 100 priority and whatever main profile you like; but use conservative preferably or interactive for best battery performance. Any task killer that auto kills all tasks with screen off (be sure to add SetCPU to ignore list). And here is the most important step, use an auto android booting app with minimum boot time setting. I have been doing some experiments with this and found that if you boot into Android as soon as possible, it seems to give better battery performance as opposed to playing around in WM then booting Android. Have tried this with several WM/Android combos. For the first time ever I'm able to get comparable battery performance out of Android as WM. I'm running a bare bones WM (but should work with and WM rom) and using Exceller Multiple Build Loader app set to 3 secs. Even running several sense builds I was able to achieve 3-7 mA draw during standby according to current widget. Took my phone off the charger at about 6:30 a.m. and it is now 11:15 and I still have 25% battery left after pretty heavy usage on standard battery. This is as good or better than what I usually get from WM! Hope this helps.
This was the one thing that was ruining my Android on HD2 experience. I finally got this step right after a few tries.
I've been using it for two days now, and getting consistent 5-8mA readings on standby. There's definitely something to either booting Android quickly and/or hitting the back button to turn on the LED backlight on the buttons.
I just checked my phone, and it's reading 5mA.
And I don't even have SetCPU on my phone. Should I try it out?
I think HTC winmo sense is the culprit. I disable the sense in winmo and get very low Android battery usage during standby. Sometimes around 3mA.

I also suggest to disable sense and put wmo in offline status.

why should turning off sense be good when it comes to battery usage under android? this would mean winmo and sense are running in the background of android...which is not the fact!

You had to try this 2 times before it worked yet you claim this is the final solution for battery drain problems?
i agree with you guys but let me just throw this observation into the mix here. i've read somrthing here in these forums regarding the sd card that came with the phone had something wrong with it ( don't really remember the exact issue ) and if you swapped it out for another sd card, there would be less SODs and a better battery as well.
i've tested this as i have a 4gb sd card and have had no problems whatsoever. everything runs smooth as silk. and, once again, the battery life is great.
NOTE: i do use the keypads lights on trick as well.

Please re-read the post. i updated
Most of us don't need to do keypad gymnastics to get those same results.
Just use the exceller boot loader and set it for 3 or 6 seconds. Having stuff turned off till you need it is a great way to preserve the battery.

Ya thanks for the comment, i was doin this in between class so i didnt have time to just try the Excellor Boot Loader!!!
Updated the First Post Thanks!!!!
well now we hav almost 48 hrs of battery life on android... and moreover i info radio 2.14.xxx is better than 2.15.xxx in battery life...
Not working for me
Sorry thats all not working for me
i'm still having about 60 mA with VBNROM reloaded - 2.15.50.14/ Bangster 1.5 / Scandisk class 2 - 8 GB
I realley tryed everything and have read a lot of posts. I'm really distressed at the moment.
The best battery cosumption i ever experienced was with mccm 2.5 But that one was not stable for me.

1. Are you using SetCPU with a 245 max screen off profile? 2. Are you disabling WiFi, data and GPS when not using it? 3. Are you using a auto task killer with only SetCPU and Current Widget in ignore list? Also, I don't have 3g in my area but if you do I guess it could account for increased battery drain. If you're in an area that is in/out of coverage, this will cause higher battery drain as well. I get spotty coverage where I work and the battery drain is terrible.
Try mdeejay sense rEVOlution 2.0 androind build with your vbn wom rom - works great !
Try this:
1. switch phone radio off in winmo
2. power off and charge until green light comes on
3. boot winwmo on vbn, then immediately click on EBL
4. boot into mdeejay sense rEVO 2.0
5. turn sense off and use LauncherPro
I get *very good* battery life now with avg 5-7mA draw as evidenced by currentwidget.

a few things to try
1
boot into android as quick as possible, 3 or 6 seconds
disable gps location in android
activate the lights when haret is loading
disable wifi & 3g
disable hotspot
disable sync
running htc sense? try a build without it
and many more attempts
im finally at 3mA in airplane mode, 5mA on phone, 7mA with wifi, 20mA with wifi & 3g

no need for keypad gymnastics or other weird and wonderful combinations - before booting into Android, just use KeypadLedControl to force the keypad lights to stay on, then fire up Android using your loader of choice (I use Android Loader, modified to automatically call KeypadLedControl to turn on keypad lights, instead of just letting it run on WinMo startup).
Been rebooting 5-6 times now with consistent low 5-10ma standby current.

The Solution....kind of ;-)
Thx for u'r replys.
I considered all u'r tips and sry dudes it didn't work for me I think the problem was related to the Bangster Build, even though i have been lonesome with my issues.
I changed the LED lib, and tryed to let the LEDs on while booting, set CPU is in condervativ mode/screen off 245min/245max 100% interactiv. And yep, GPS and Wifi where off. I even searched for any SD-Card related Problems in regestry. But Chucky did some great work i think. (i switched again concernig to faster boot)
At some time i think each Leo is different to the other. I changed to Hyperdroid 1.7 with 2.14 Radio and the results are definitely mind blasting.
12 hours on the road, did some surfing, some calls, 2 h musik.
Strange though i used the same kernel and same Radio. Something must have gone wrong by flashing Bangster or something.
So you did flash, and you are running WP7 on your HD2.
Now the battery dies quick?
Firstly, download this ROM and flash it: (google your ass to find out how its done, dont ask me )
http://forum.xda-developers.com/showthread.php?t=941905
Its a custom ROM by football. Works amazing. Better than original ROM or the Moonlight (another custom rom) shiite you're planning on running.
After you have this ROM (or even if you dont have this ROM) if you take care of the follwing things, you will get HUGE battery life.
1. Fix the indicator by installing Registry editor, charge your battery to full and follow following steps:
http://forum.xda-developers.com/showthread.php?t=933751
Thanks arkatis!
2. See that you have a new sd card, not the one which came with your hd2 orignially, buy a new one, any branded one should do, and rplace it with the older card and in your phone go to: settings> about phone> hard reset
These two steps will really show a massive imprvement in your battery life.

Are you able to list even one of the performance difference's between this rom and the Moonlight rom?

well, for astarters, ml has a higher call drop rate, the voice quality over the call isnt all that great either, im on x.12 radio, and its not able to use the radio perfectly - this same problem is not there on footballs rom.
Another bug is while recieving calls, sometimes, when you click "answer" it automatically puts you on speaker phone! Its scary when you dont want others to know who just called. (happened twice on ml)
gps lock took nearly 5 minutes on ml, on footballs rom it snaps on in less than 30 seconds.
thats why i had to switch to hd2 1.00
Odd how I haven't had any of those problems. Anyway there is no difference between this rom and footballs rom. The tools to make any of those kind of fixes aren't out yet. The only kind of change you'll find is simple things like different keyboards or installed apps.

I did both, but there is no improvement in battery life. lasts less than 12h as before...
I will try the hard reset part when my new SD card arrives
Hold on there a sec, top be clear buying a new SD card might not work at all!!
If you dont have lots of cash or you dont have another use for the SD card please dont go spead money on something that may not work!
Not all cards, even within teh same brand and model will work!
and the reg fix doesnt improve battery life, it just lets you know what you have left, most issues with apparent high consumption are because a your phone isnt fully charged yet windows reports it so, apply reg fix once charged, restart and charge again you may been to repeat process, and to check use the HYC battery tool, try it pluged in and unplugged and you may notice a difference, if you do, restart and plug back in again to charge the remaining battery
I am using Moonlight atm..and with calls/sms and wifing i get utleast 1 and a half day..I use my tweak everytime i charge the phone and seems alright!
I am so obsessed with WP7 so i maybe get an official WP7 mobile..i am thinking of Omnia 7..Looks good!

I actually got the best battery life with the card that came with my HD2.... I've tried 8 different cards with wp7, too... most of them bought recently. Just buying a new card doesn't mean it will work with WP7. Your best chance of getting a good working card it to get a class 2 sandisk with part# ending in A11M.

I only seen this now! This just proves you haven't a clue what you are talking about!!
I'm using the Moonlight-Rom and I tried the last Radios (2.12, 2.15, 2.14)
And the winner is 2.14 - used the phone a lot (games used Wifi...) and after 12h I've still 25% left.
With the other Radios I had to charge it after 9houres because it ran out of battery without using it that much only some SMS!

Hey,
at least we could talk in german, but the others should be able to understand our conversation
I also tried many Radio Roms and my fav is 2.12, bu to be honest I only tried 2.10 2.12 and 2.15.
Do you really think, that the 2.14 is better than the 2.12?
Ja dann machen wir das in deutsch... ;-)
Yes The first Rom I tried was 2.15 (it was already installed - previous rom)
Then I read that 2.12 is working very good and because my phone needs to be charged after less than half a day (using 2.15) I tried 2.12 - but I still had the same problem.
Thats why I decided to use a other Radio! And it seems to work!
Maybe it depends on the phones too?
I dont't know - Try and Error....
I too don't think the registry battery fix works. First time I ever installed WM7 ROM was football's and never changed it. Tried the battery fix a few times with no luck.
Had Radio 2.15 and downgraded to 2.12 with no luck. I see some have improvement with 2.14.
I took out my SIM card yesterday to try if SD card "helps" in battery drain. Left wifi on and played with internet for a bit. This morning it had like 90%+ battery left in it. So it's not the SD card. IMO Radio is the major culprit for the battery drain.
I'll try 2.14 tonight.

That is what I am feeling too! In an other forum I read, that it could be helpful to release the battery for 60s before charging it. But I don't want to do this every time I charge my phone

What is that for a tool?
Found it somewhere here.... @ XDA
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.

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.

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 :
http://forum.xda-developers.com/showthread.php?t=1048649
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.
Before I get flamed I have read all the comments I can find on WP7 Rom battery tricks i.e. camera record after reboot trick, leaving 3g on etc. All Im asking is if other HD2 users are experiencing as little as 6-7 hours of battery life on WP7 roms, iv'e tried xbmod, HD20 and YukiXDA and have tried this thread http://forum.xda-developers.com/showthread.php?t=978101.
Phone is hardly used, no phone calls just settings and odd text message and only wifi on when using phone.
I'm gutted because I love WP7, any advice appreciated and am not trying to "Noob" up the forums I just wanted to start a dialogue with other WP7 Rom users.
Thx
Nope, that´s not normal.
There are several possible reasons for your problem. MAGLDR, Radio ROM and SPL versions are crucial. Bad flashing can happen all the time. Plus, an "incompatible" SD card can bring a hell lot of issues, too, as well as an "old" SIM card.
Anyway - I can say that under WP7, I could not reach the same battery lifetime like under WinMo 6.5 - you can more compare to Android (NAND versions). Maximum 2 days at really low usage (week-ends), 1 day with "normal" workload. I could easily double that time under WinMo 6.5.
The HD2 likes battery like i like beer.....as much as possible in the shortest amount of time.
My phone and wifes phone (exact same phone + ROM) work for about 7 hours. ive tried many different tricks, radios, ROMs and no luck. luckily at home and work i have access to charging points, so not so much of a problem. just anooying when we go travelling!
Try latest YukiXDA Rom with 3G on. My phone lasted a day and night ( few calls, texts, games (including installing) Facebook etc. Much improved.
i'm using yuki's latest and mines dead in about 7 hours also (without even using it cos i have a company phone) but some have reported 2 days , i've got the battery tool and my current is usually around -250 sometimes higher before and after camera trick but some have reported 2ma ,, i'm sure i'm using the bat tool wrong lol . gigahurtz whats your current

After installing a number of apps from the market, battery drain issue happens again.yuki xbmod v2 radio 5.51T HD2 EU.
uninstall apps. no go.
reboot and do camera trick. no go.
reset phone fixes issue.
i read from somewhere that putting 5 albums in the SD card also results to this.those who are using toms XAP installer pls send feedback as im not sideloading for now.
any ideas?

My sister has the same problem on her HD2, I told her to order a new SD card. Class 2. I'll post if she has any success.
Does this trick: http://forum.xda-developers.com/showthread.php?t=933751 still works in Mango version? Becouse i have a 5.51t software radio version and 2.15 radio on my HTC HD2 euro version and camera trick doesn't work for me. My battery drain after 4-5 hours (sic!) of using WP7. (music, internet connection etc.). Battery stats show -220 drain. Is it normal? Any solutions?
A Random Battery Fix!!!
Hi all,
I am running mango 7720 (v2) - radio is still 5.69 for 2weeks now.
Have installed both radios 2.15 and 2.12 without any luck in regards to the camera trick. it worked upon a fresh format (-5ma), few apps later i am at -74ma. Battery lasts 9hrs 3g on, barely any use!!! dropped over 90% overnight.
I am aware that 5.51T/5.51 radio fixes this problem but i am waiting until XBmod releases the radio package without the need to format the phone.
I am running radio 2.12 for a few days now with horrendous battery life, until i came across something random.
Now, my drain is at -4/5ma and it lasts well over a day with 3g on. This is what i did (tested for 2days and loving it!):
Connect to wifi, turn off phone, turn phone on, do camera trick, turn wifi off, turn airplane mode on, then off and there you go!
Have tried doing the trick with/without reboots/wifi/airplane mode touched, - all failed!!! How weird, yes?
Hope this helps others.
God bless you XBmod-Yuki

I installed about 30 albums and sideloased a lot of Xaps.
Cameratrick does not work anymore. After fresh install of Mango 7720 everything was ok. Radio 5.51T and European HD2

Did you sideload any apps after the fresh install though? Been running 7720 on my TMOUS with 5.51T and it was great for about a week, then after a full charge, battery saver would show that i'm losing a percent about every 10 mins. Battery tool says i'm getting between 4-10ma on standby so i find it strange. Battery saver used to say time remaining would be 1 day and a few hours, but now on full charge it says 20 hours. Is battery saver even reliable for its readouts?
I really don't want to reset my phone (done it about 10 times) but if this will fix the drain then I will.

Is this trick working???
Please reply
Bluetooth seems power hungry when phone is idle
I have lots of apps & music installed and great battery life as long as i switch off Bluetooth when not in use.
To test standby current correctly:
Launch Battery Tool,
Lock phone,
Wait a couple of minutes to make sure phone has gone into standby.
Unlock phone and wait 10 seconds for reading.
Bluetooth enabled standby current ~100mA
Bluetooth disabled standby current ~6mA.
I am in a 3g area and Wifi is enabled.
