hmmm i don't get it:
after doing a successful flash according to virnik0's procedure http://forum.xda-developers.com/showthread.php?t=818556 everything was fine - for a couple of weeks or so..
battery would last for days and days just in standby - then suddenly it started to run down pretty quick - now it lasts not even 24 hours - and that is even without any usage at all - just lying there on my desk - idle..
i have absolutely nothing running - no wireless - no programs running - only the mobile network connection - all other programs stopped..
i even bought a new battery - but same problem - less than 24 hour standby on idle.. not even making 1 telephone call..
i also tried resetting the battery..
would it help to do a complete re-flash?
My first guess would be, that you installed / updated an app which goes crazy now.
You can rule out every app that is preinstalled, from google or commonly used (such as titanium backup) .
You can try to uninstall these apps one by one and see if the drain persists.
If so I'd flash a full ROM without installing additional apps. After that you'll have to wait 2-3charges until the battery indicator is accurate again. If the drain is still there it could be a hardware problem.
I think reflashing will fix the issue but don't hold me to it
good luck

I am having the same issue. My battery after flashing 2.3.3 JVK was fabulous. now it is not even lasting for a complete day with no wifi and 3g.
I guess i did wipe the battery stats , after which i am getting these crazy values. I am going to wipe the battery stats after my phone is fully charged and see if anything happens.
i guess there is a guide somewhere in these forums that we have to complete recharge, do a wipe and completely discharge and do a wipe again. please have a look at Battery issue threads in XDA.
Hey, check this thread, there are some interesting observations.
http://forum.xda-developers.com/showthread.php?t=1021711
I don't really believe in wiping the battery stats. They have to be rewritten and that also takes time and gives confusing values in the mean time. Just using the phone normally and always discharging as low as possible while always charging full is my approach.
With JVK it's another story, I think no one knows exactly what causes the drain. it could be the update but I also suspect the gallery, I overwrote the gallery3D.apk with a 2.2.1 version and the drain seemed to disappear. But that's not even a observation, more a feeling since I flashed an restarted several times in the past days since I flashed JVK so I'm more or less just trying a lot at the same time and hope something works
Thank you theduckking - yep did that too - uninstalled all apps not needed but still draining too much - so I am inclined to re-flash..
So you say I can try just reflash ROM - is that also via ODIN? and how do I know which ROM to flash and what it is called?
lycan_codex - yep I did do a battery re-set also in recovery mode - following the procedure from another post - didn't help either
I recommend Odin.
It doesn't really matter which ROM, you could take darky's resurrection edition to have a minimal odin rom.
but flashing a romkitchen (wipe) rom through CWM should also do the job
or you head over to [Ramad]'s thread choose a stock odin firmware (some scrolling required) and flash that.
If you find, that the drain is fixed after installing a minimal rom, you can flash a bigger/fuller ROM over it through CWM and customize it and live happily ever after.
After unplugging the phone turn the camera on and record for about 15 secs and your battery should last for about 2 days or longer. I tried it on 3 different HD2 with WP7 and it worked perfect
I know it sounds stupid but don't judge it before trying it !!!!
If you try this pleas let me know if it works with your HD2 too

The trick works untill you reboot your phone or change battery.Then you have to do it once again.Thats it.
The only solution that worked for me amongst all the options (based on my experience)
1. Tried the camera trick - NOT WORKED
2. Followed the steps below - NOT WORKED
* Boot the phone to MAGLDR
* Select "Reset" option from the menu
* Phone reboots normally
3. Hard reset the phone - NOT WORKED
4. Charge the phone in magldr USB storage option - NOT WORKED
5. Finally, flashed the 2.12 radio, did the camera trick (not sure if its relevant). The battery life has improved dramatically. It lasts more than 24 hours and still running (26% left) - WORKED.

my experience not good with 2.12... draining battery is improved with 2.12 on my device.... in stand by battery drain is 40% in 6 hours... with 2.15 is much better for me...
Thanks OP, will try this.
I read that SD cards are the main cause of battery drain.
I have changed the radio from 2.15 ---> to 2.12 , Better sound better signal , Battery but we have for sure a bit of duration improvement not something extraordinary though .
BUT !!! i Have experienced something else.
I have bought a Chinese battery 1650 Mah and i left the battery drain completely.
(you need to be careful with that point cause after the windows will not start if no power !!!) and then the battery can charge (from the HTC official charger) only up to 60% and it lasts more than one 1 day simple doing nothing on the phone . With normal use lasts only max Half day.
But when i charge the phone to Pc or rapid travel charger the battery completes the full 100% capacity .I Believe that this has to do with the software & battery that do not recognize probably the full capacity,
Keep in mind that if the battery is charged up to 60% with the official charger I gain better duration than 100% charging from PC.
…still a big mystery the battery on mango !!!!
Thank you very very very very very very much i'm gonna try it
Good !!!!!!
Different radios never worked for me so I just stuck with 2.15.
Indeed hard to believe, but the video trick helped! Before the Battery was down in about 10 hours, now 8 hours passed and still 75% capacity. Thanks very much!
German HD2 from O2 with mango 8107.79, followed this thread installing it with xboxmods autoupdate. Great work, actually much easier than installing most commercial software packages! ;-)

Mine is the same way. Just a few minutes (10 to 15) doing things on mine from a fully charged battery and it goes down 20%.
I think it has more to do with magldr than the ROM, though. My other HD2 is using a cLK version of Tytung Android and it is the actual first Android build I've ever used that has acted like a stock ROM. The battery life is great and in standby it stays charged really well. Not so with the magldr version. In standby with the same ROM booted with magldr, the battery drops quickly.
There are people here experimenting with different radios to try and get the battery drain down. Both the hardware and software radios and different combinations of both.
As changing the hardware radio is easier at the moment than the software one (you have to re-flash and update to mango), you may want to try that.
Good luck
I have the same configuration but mine works fine (after doing the camera trick the battery last more than 24 hrs.). Maybe it is due to the battery lifetime, capability, quality or any other hardware issues.

its one thang to have fast battery drain but for the system to display faulse info in the system settings and be totaly inacurate?
whats up with that?
Everytime you start the phone or after a reset, you have to do the camera trick.
Also, when you take a picture... before you shut down the camera, do the trick again.
After the MANGO installation, also download and install 2.12 Radio. That seems to be keeping the drain down a little. After I installed the 2.12 radio AND keeping an eye on the camera trick is done, the phone lasts for 1 day and 9 hours. (It's been 1 day and 10 hours now, 11% left...)
update 2.12 rom works!
update. I flashed with 2.12 rom, then did a factory reset, then camera trick.
Now 16 hours after the charge, made a few phone calls and some light internet surfing, I still have 48% battery. This is a remarkable contrast from yesterday. Don't know if this is due to 2.12 or the camera trick, but the combination of the two definitely worked. Now I ca keep my Mango
Thanks all for the help

I also flashed 2.12 earlier today and have just now done a reset (in the "About" menu) and am going to see if it helps with the BL. Mine was down to about 45% after just probably 3 or 4 hours...in standby. Not being used at all.

Regarding flashing the 2.12 radio and then resetting it, something helped. I won't say flashing the 2.12 radio helped because I flashed it first and later I did the reset. My HD2 still drained faster than an old Chrysler sucking gas through a straw. But after the reset, it is still at about 85% since last evening about 8:30PM. It is currently 1:11PM the next day. So that gives me about 17 hours on this one charge. And no, I am not exaggerating. My previous post lists the time I flashed it to 2.12...actually before I made the post. And I just now took another look at it....about 5 minutes ago. It hasn't been used at all during that time period and, in fact, I haven't even set it up yet....no wifi, no syncing of any kind, not even signed into my account. After resetting it, I simply set it aside and did nothing with it. So lets see how it does after I begin using it again...syncing, turning on wireless and all.
My current is -318!!! And I only have 3G on. I tried the camera trich and it does nothing. Any other suggestions.

I'll help.
Put your HD2 in bootloader screen by powering off first, then press and hold the down-volume button and tap the power button. Hold the down-volume button till the red/green/white screen appears.
Then connect your HD2 to your PC and at the bottom is should say USB once Windows sees it.
Once you have the appropriate radio file downloaded and unzipped, open its folder and click the "LeoCustomRUU.exe" file. You may need to right-click and open it with "Run as Administrator".
Go through the checks and it will flash the radio. Once finished, disconnect your HD2 for your PC. It will reboot and your new radio is flashed.
Regarding the battery usage of my HD2 after a reset, I can report that I'm now seeing above normal battery life. Earlier today, around 1PM, I set up my HD2 and established all my accounts...3 email accounts, FB, Twitter with default syncing...and enabled wifi. All of the usual stuff I normally use except the installation of all my previous apps.
Currently the battery is exactly 70%, according to the built-in battery saver menu in the settings. It has not been charged since yesterday about 8:30PM. That's approaching 24 hours since a charge.
EDIT - I took a picture of the current battery condition. It shows time since last charge and time left on charge plus the current charge level.

I have been using the camera trick, but I don't really have faith in it that it is doing anything useful. Once I see how far this first charge will go, I will do more experimenting like not using the camera trick. Right now I want to leave my HD2 exactly like it is...not using it, just leaving it in standby...till the battery dies out.
It's actually not all that good for standby battery life. Being in standby, it should last much longer than the projected 54 hours on this one charge. My iPhone will last longer than a week in standby. My Inspire and other HD2 with Android lasts about the same as this, though.
And the reset I speak of is in the "Settings" > "About" screen. At the bottom of the screen is the "reset your phone" rectangular box.

Damn, that's nice I manage 1 day and 18 hours on a full charge, according to the battery saver app. As soon as I go to work I use the internet a little (Twitter/Facebook/IE). By the time I get to the office (40 minutes), it dropped a good 30%.
When i'm not using the phone, it's good, 1% per hour or so. As soon as I start using it a little, it goes down like an elevator on meth.
What I also noticed, is that when the signal is not very good, the battery will drain up to 6/7% per 30 minutes... i have no idea what that's about.

And you have done a reset?
Using Battery Tool, my HD2 on Mango 7720/ISV cleanup regularly charged pretty much 3/4 of total battery charge or in terms of HTC Battery Tool the charges were as follows:
FULL 1230
ACR 935
With that being said I 'd previously run NODO on 2.12 with great reception and the same charging issue. Update to 2.15 with Mango degraded my reception, battery life and preserved the charging issue. Then I started seeing posts claiming that flash to 2.12 in Mango improves the overall experience and one of them literally mentioned the charging issue which allegedly disappeared. Knowing what to expect from 2.12 due to prior NODO experience, I decided to roll it back and see what happens...
First flashed 2.12 over 2.15 with battery approx. quarter down its charge and despite better reception my battery constatly charged only three quarters of total charge. Sooo, after reading couple posts on 2.12 radio, and how the battery charges fully all the way to 100% (using HTC Battery Tool to check this), I finally decided to charge my battery in external charger and than once again reflash 2.12 this time with fully charged battery and...
No more three quarter charge . Will do some repetitive charging to test and confirm but so far it's always charging all the way! .
Hope this helps someone who's suffering the same half ass charging annoyance .
PS: Drawback to this is need for external charger or properly charging phone

Uhm... WP7 might be considering a theoretical maximum, just like android does with it's battery calibration.
Difference is, Android has on-the-go battery index recalibration. If it reaches the theoretical maximum (100%) and the charge is nowhere near 20/10 mAh, it keeps charging and set's the new maximum to the new charge (i belive it has a arbitrary battery units, at least Android on HTC Kaiser does).
What you're saying is, only flash WP7 if you're charge is at, or near 100% on WM6.5/Android Otherwise WP7 will waste battery charge

Even better... In case that your battery does not charge properly there is no need to repeat WP7 install, only reflash your radio .
Yes, you may ask how device radio rom could have any effect on WP7 installation which comes with it's own radio drivers after all, but today I can attest that it does. My phone is regularly charging all the way to 1190 out of 1230 all the time as opposed to post Mango Rom flash value of 935 and all I did was reflashed device radio with fully charged battery .
Appreciate the Android analogy .
PS: I presume that it does not charge full 1230 due to phone not charging in USB flasher mode and during flashing process

I suppose it's HTC HD7 based as far as drivers for individual device components go. After all, people who are getting their new WP7 Roms activated (on HD2) literally tell Microsoft customer service reps that the activation is for HD7...

Hi.
There is no other way then complete WP7 Rom reflash if you'd like to switch actual WP7 radio but hardware level radio driver (OS independent) can be upgraded/degraded without resetting or reflashing your phone . Note, I am talking about radio e.g. 2.12 and more as made available via the link in post #1.
With that being said, if there's any radio on that list that suits you or if you're in possesion of Australia compatible radio then all you have to do turn of your phone, next hold volume down --> power on your device and wait for the rainbow screen to appear (kernel flash interface ). Once your phone is connected to PC, your interface type will change from serial to usb and do your thing as instructed under the radio rom link in post #1. Let us know how do you and if there's anything else that could possibly prove helpful
Regards to Australia
Interesting.....
I was only getting a 75% charge with Mango and 2.15 so i flashed my radio back to 2.12.
After an immediate restart the battery charge graphic then showed 100%. Weird.
As the amber light was on I left the device charging into it changed to green. I then reflashed back to 2.15 and I have been getting a more accurate battery charge graphic ever since.
Ooh and the bonus, my battery is lasting longer between charges. Yey
Are you supposed to charge the device until green before flashing?
How long does your batt. last? On the worst day I had 4 hours batt. time (with BT on and WIFI on).
Today without WIFI and BT on the batt. seems to be lasting something around 15 hours.
I fully charge to green before I do anything nowadays.
I rarely use WIFI but I do have two email accounts set-up which check for mail every 30 minutes. With moderate talk time and two hour train surfing time I'm getting about 20 hours between charges. Which is considerably more than before.
my battery loses 10% on 30 mins, that's so LOL..
I have 7720 with 2.15.. with camera trick..
i'm gonna try the 2.12.. just a question, DO i need to HARD-RESET(by phone7 about screen) after the radio flashing?

Hi...no, do not hard reset your phone at all. Whenever CustomRUU completes the ROM flash procedure, simply close RUU on your computer screen and your phone will restart (you will be exiting the rainbow/kernel USB interface). Mango install will be fully functional just as before you shut it down prior to flashing new radio .
Srry to hear about your battery drain issues...hope this will help to decrease it by a lot.

I am facing a severe battery problem with my mini (not the well known battery consumption we all know about, this is something else).
First I thought there is something wrong with Windows Mobile and I hoped when going to the NAND version this would be solved but it is not.
Let me first explain what is going on. When I charged the battery on Windows Mobile it would not go higher than 40%. Even after one night it is still at 40%. When I unplug the phone it will drop to 5% in the next couple of hours. And then it will remain at 5% for more than 24 hours, sometimes even 2 days without shutting down!!!
So it is not the battery which has no capacity but the battery level which is completely wrong... This all started when I first began to play with the SD version (may be a coincidence?...)
With the Android SD version and now also with the NAND the battery will charge to 100%. But then it drops very fast and after two hours it is at 5% and then switches off. It seems as Android does switch off the device earlier than Windows Mobile. So I cannot use this at all, my mini will only run for two hours on Android while on Windows Mobile it was running for several hours at 5%...
To make sure it is not the battery I bought brand new batteries. Until today I bought four (yes 4!) new batteries but all have the exact same behaviour. With the last battery I bought I did go into recovery before booting the phone for the first time and cleared the battery stats. But still, the exact same behavior.
Does anyone have an idea what the problem could be? Is it a hardware fault of my mini? Or is there a little piece of code for the battery which is not overwritten when flashing NAND?
What could I do against it? Is there a way to prevent Android shutting down on low battery? As it seems the battery is not empty at all but Android thinks it is empty... Or can I somehow tweak the battery level? Let's say always add 5% to the battery level so Android will not shut down?
Any help would be highly appreciated!! Thanks!
Try task 2a than task 29
Munjeni, please forgive my ignorance. But how can I perform these tasks? From recovery?
Google is your friend . But only found those "task" fixes only related to HD2 and other phones, does this also work on Mini?
Yes, it working! Swisly, you need mtty.exe to perform task 2a and task 29, and you can not do it with recovery.
Ok, thanks. One more question: what is the equal to "POWER + Record + Pen Reset" for the mini? Do I need to flash back to Windows Mobile first?
No, go to 3 color screen and perform mtty tasks, after this you need to install wince becouse your device will be totaly erased

Click to expand...

I managed to do a task 2a and a task 29, flashed everything from the beginning but unfortunately no luck. The problem remains...
I found an interesting thread here. http://www.slatedroid.com/topic/20337-battery-level-fix-for-512-firmware/
They somehow managed to adjust the fullvoltage and emptyvoltage. With this I could prevent the mini from shutting down too early
But I have no clue how to do this. Can anyone help me with this? Or is there an easier way of doing this in CM?
Thanks!
