[Q] Battery - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

Dear XDA members,
I've just reinstalled WP7 after Android, but my battery life is very short (approx. 5 hours after full recharge). My procedure:
1. Back to WM6.5
2. Install HSPL 2.08
3. Flash radio 2.15
4. Install MAGLDR
5. Install WP7 (HD2O ROM)
6. Hard reset at '1234...'
Now, when I check Settings > About, my software radio version is 5.71.09.02a_22.51.50.21U. Shouldn't this be 5.51? If so, how can I fix this? And is this the problem regarding my battery life?
Thanks in advance!

read battery tricks in my signature
to install ROM with radio 5.51 use Pdaimatejam ROM or manually replace part00.bin in data.zip file (look first link in my signature)

Thanks for your reply. So I can just download the Pdaimateja rom, extract the radio, put it in the HD2O rom and flash it again?
Also, I've used the HD2O rom before I switched to Android, never had any issue with the battery (it lasted for approx 20/24 hours). How's that possible?

Alright, I've tried to flash the rom again, now with the 5.51 radio extracted from the Pdaimateja rom. When I check Settings > About the radio version is indeed 5.51, but the problem is still there. Battery life seems to be a bit better (approx. 6-10 hours after full charge), but still not what it used to be (approx. 24 hours).
Something I noticed today: when booting to the tri-color screen, on top it says: "PB81*** HX-BC", I can remember this used to be different. Should it be different?
To be clear, I have a (non T-Mobile) European HD2.

did you use camera trick and other battery savings tips?

I've used the camera trick and now using radio 5.51. The weird thing is, I've used the same rom before, back then the battery life was very good (approx. 24 hours), now with the same rom my battery life is much shorter, while I use exactly the same apps and settings. There must be something wrong, maybe I've overlooked something... What about the "PB81*** HX-BC" at the bootloader? Shouldn't this be something like PB81100 HX-BC? I can remember it was like that before, but don't know how it changed.

I'm sorry to bump this thread again, but I'm still curious about this.

nothing changed... yes my device have
PB81100 HX-BC
SPL-2.08.HSPL 8G XE

So there's nothing to worry about? Since every screenshot/video I see of the HD2 shows something like PB81100 HX-BC instead of PB81*** HX-BC.

I switched to Clean ROM - Stock UI, and now my battery life is 1 day and 15 hours after full a full charge. It's a huge difference, so I'm staying with this ROM

i have almost 2 days of battery use (WiFi and data is turned on non stop) with Pdaimatejam ROM and original HD2 battery old 2 years...
very important it is if you know how to use ROM... SDcard maybe also can make difference....

I use the same SD card, and since I'm a student I can't afford to test multiple cards To be honest, I don't like all the extra apps and modifications on the Pdaimatejam rom, so I will keep this rom for now. I noticed battery life decreases a bit after a couple of hours, but it still lasts approx. 20-24 hours, which is good enough since I charge my phone every night.

Extreme battery usage with non-official ROMs

Hi *.
Two days ago I've installed HSPL and flashed with Dutty's ROM 0.3a. During installation of programs, I've noticed extreme battery usage. 1% every one minute or less! It was almost impossible to fully charge phone.
CPU usage was at minimum level, 0% for most of the time. So I did hard reset but even clean ROM act the same. Today I've tried two other ROMs: Miri's v2.0 [Sense 2.5] and Artemis' v2.1 - same thing.
Quick decision - back to official ROM [1.48 WWE]. It helped. Now 1% of battery, with screen turned on, lasts for about 10 minutes.
Any idea what might causing this? I don't want to be stuck with official ROMs
Possible the radio.
If I remember correctly, Dutty's rom comes bundled with the radio 2.06. So you might want to try flashing another radio from here:
http://forum.xda-developers.com/showthread.php?t=611787
I'm pretty sure that's the culprit. Good luck man.
Didn't help. I've flashed Dutty's ROM again, than Radio 2.05.51.05_2 from 1.48. Battery drops 1% every 2 minutes (3G without data connection).
had the same with that ROM, using radio 2.06.
could't find why. definitely not all cooked ROMs are battery eaters. there are several, but 2 i remember that are nice for your battery are energyrom and of course miri's
try one of those and report back if it's better
I have XannyTechs ROM on my HD2 and I think the battery life is very good, even better than when I had stock ROM.
I have been using Dutty's ROMs since his first release... No battery problems whatsoever.. Actually i have seen an increase in battery-time compared to the stock 1.48... Remember to flash a stock ROM in between your cooked ROM flashes... It keeps the device clean from unused and unnecessary garbage.. More over i also hardreset after each flash... I have seen no problems with this procedure....
BTW. I have the 2.06 radio... No battery problems

You cant just flash one radio then give up. You should try all of them, give each radio a couple days to see its performance.
Correct, plus you have to do some charge/discharge cycles for your battery to better adapt with your newly flashed ROM.
After flashing a custom ROM, don't remove it immediately but do a full charge, let it discharge let's say till 10% then do it again, and also when fully charging let the phone for at least 10-12 hrs in charge although the light has become green.

re:
I use the 2.06 radio on Topix version 1.1.3 and it seems to run forever. My HD2 is running round 5 days with one complete load!
if the battery drains are huge and strange, use mtty.
Im running Dutty's original ROM and its improved my battery life greatly. It shuts down the WIFI etc when the sceen is blanked out and instead of draining battery 30-40%, my battery drains about 8-9% over a 10 hour period. (Without bluetooth enabled)
I have nothing but praise for the ROM i am running atm my phone is better than out the box by factor 10.

It's quite hard to give each radio couple of days. Phone lasts less than two hours without charging. Became kinda stationary. I've tried all radios (with Dutty's ROM) with 1 batery cycle for each, same thing.
Yesterday I've again flashed original 1.48 and then ROM which doesn't update Radio - Artemis ver 2.3, and... still the same story :/ So looks like it's not radio-related problem. Maybe something with HSPL? Could it be a reason?

I don't get it, what changing ROM has to do with forming battery - something you do after buying a phone? Mine HD2 is 2 months old. Nevertheless since yesterday, after flashing Artemis' ROM, phone was fully charged, discharged during night and plugged again at the morning. Didn't help.
Another thing is, where this energy goes to? Doesn't look like radio problem, CPU stays with minimum usage.

do u switch it on sometime? lol
really 5 days? and what do u do in those 5 days? i mean how u use phone...just for call...navigate...watch movie (i watch a lot of moovie in freeworktime ) listen music? just to understand...
im using tom 1.1 and has a not very good battery usage but i keep all automatic updates all the day,100% backlight level...honestly i never tryed to empty all battery with this rom but ill try today watching some movie and tomtom for hours in car...ill let u know a report
ok i stressed a lot my phone this afternoon
14.30 100% battery
Facebook,weather autoupdates every 1 hour
max backlight,always connected to 3g
browsing for 30 min
tcpm movie playback about 125 min
10 min of tom tom and other 30 in background under tcpm
15 min calls
now at 18.42 still have 8% battery
running tom 1.1
I've done some test. Because HSPL was always present in flashing non-official ROMs, I tried SSPL and two ROMs - Laurentius26 v2 and Dutty's v0.3a. Each time flashing official 1.48 before, to restore proper battery usage. Same thing :/ Seconds after new ROMs were booted battery started to drop immediately.
So it's not related to SSPL/HSPL. There must be something inside all those ROMs [Dutty's, Laurentius26, Artemis', Miri's] what's causing problem. But what? Any ideas? Please.
p.s.
Dutty's ROM (with HSPL) was in phone for almost 48h, nothing changed in battery life during this time.
Following makeveral's advice, I've tried MTTY. Quick 1.48 flash to clear everything, next HSPL, than MMTY and finally Artemis' ROM v2.5 from SD card. And guess what, same sh*t Battery drops 1% every 2 minutes or less, CPU usage around 0%.

Have you tried to replace the battery? Very probable that you got a faulty one.
1.66 stock
I had same issue with Cooked roms, So decided to upgrade to stcok rom.
6:00
100% battery
40-50 calls,
15 mins of internet browsing.
30 mins 0f tweet.
Automated (15 mins whether update, 1 hr mail, 1hr tweet)
16:00
battery 76%
19:00
Battery 70%
2hrs of Music Battery 43%
And at 22:00
37%
I suffer from the same issue, though not as bad as you. My drain is about 5% an idle hour on a custom ROM instead of the more normal 1%. Hope you find something, I will be looking also.
Did you try this little app?

Better battery life on HD2 WP7

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

Merci
Hi
I ask if i remove the battery or i charge the phone
should i make this again or not
thank you
hi
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.
Follow the thread below to download the 2.12 radio

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! ;-)

HD2 7720 very bad battery life

OS: 7.10.7720.68
radio: 5.51T.09.29a_22.32.50.10U
Battery tool/Battery Current: - 138 !!!
Yuki back to the future rom.
My battery only last 10 hours standby! by end of the day, the battery is completely dead! Tried the camera trick, but this version of rom had green button mapped to voice dail so just went to camera tool, then go to video and
autofocus. Does not seems to help.
Anyone have solution? With this kind of battery life, I would have to revert back to wm6.5

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.
i dont seam to recall haveing any battery issues on yuki v1 but after i update to v2 i strted experianceing fast battery drain auto focs trick with camira dosent seam to work ither i updated all the way to 7200 i was still not happy about the battery drain tehn i install teh device provisioning and isv beta clean up through zune hopeing to fix my batter issues it didnt i gave up then i wanted to get wireless radio and installed DEV_FM_ANTENNA_INTERNAL.cab and now its even worce i littery wach 17 hr's of battery life dran in 7 min's

i thought only people wear wrong not computers opps gess i was wrong because to me this seams like a fatel error!
the system menu is displaying faulse information
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.

Like this, but don't back out of the camera, tap the homescreen button. You want to leave the camera running in the background.
--------------------------------------------
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.

When you speak abour reset, it is the"Parameter/About/reset"? To gain this autonomy you still use the "camera trick"?

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.

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.

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.
update: the camera trick is spradic.not working no more im back to 10 a day standby. i will give up and flash back to andr9d this wkend

And you have done a reset?

Possible battery trick addressing improper charge issue in 7720 after ISVcleanup

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

Hope this will work also for some other people .
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
Question, on what wp7 phone is our version based ?

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...

Have I missed a post somewhere, how are you reflashing only the radio? I have been wanting to change my radio to one better suited to Australia. I was loathe to go through the entire process of WP7 install again, when essentially I have a bug free functioning install.

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.
Let us know
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.

[Q] battery issues after testing mango. help please

Hi to everyone
after death of my previous hd2, i bought a brand new one with fully working battery
i installed wp7 with no problem, but changed back to wm because it wasn't my taste. but after that, something strange is happening. my battery works fine, with regular rate between 100 and 60 percent. but after that, it suddenly start falling down (60 to 10 percent in half and hour) no hidden active program or network activity
i tested everything. tried different roms, radios, even getting back to original spl and stock rom. but nothing helped
is installing wp7 capable of damaging the battery?
is there any way to recalibrate or wipe HD2 battery?
does anyone have similar problem?
thanks
Hi!
Have you tried running you battery completely down and recharge it fully again several times? That "trick" helped me get some more juice out of mine Seems like the OS can't read the voltage correctly before it has had several complete cycles...
