Power off without Warning

Hey friends,
i am using p3400 with windows 6.1 custom rom.
Recently i degraded from windows 6.5 to 6.1. I am not sure if this is the cause for my present trouble.
Now my phone's battery is misbehaving. My phone switches off with out any warning when i am talking or browsing or listening to music. The battery charge before these things happens are no where close to battery drain level. But when i try to restart the phone won't power up as if its battery is fully drained. Then i will have to connect my charger to switch on my phone.
If i have my charger connected when i am browsing , then i am not facing these issues.
If anyone have any information regarding this , plz do respond.
Thank you
regards,
Jerin George

Same here
same is happening with me.
am using 6.5

that's a problem of rom.
complain to cook. may be they has removed some necessary files !

Thanks for your reply.
I am using rom from the file "gene_wm61_wwe.rar"
I have used this for around 4 to 5 months before switching to "Ultimate V7 Old Gene Mega Manilla Version". I encountered nil error with the working of the device those days.
After using "Ultimate V7 Old Gene Mega Manilla Version" for around 3 months i though of switching back to my old rom version. After which i started observing these issues.
I have also seen one more problem. Whenever i restart my device , My clock setting are not saved.
I end up correcting my clock setting each time i restart. I think my backup battery too got some problems !!

Jerin

Hey guys,,
No one to point me out of my misery !!!!!.
Made one more observation.. I changed my rom again to confirm if its the problem caused by rom.
Even with the new rom i am facing this same problems.
These problems will make my phone "Less Mobile ". it always needs a chargers assistance to work !!

Few steps which i tried But no improvement
1. Soft reset
2. hard reset
3. Clear storage
4. Un checking today timeout
5. Disabling advanced network functions in USB to PC
6. disabling touch flow.
7. battery calibration.
8. Keeping battery disconnected from phone overnight.
If it was just a reduced back up time, then i could finalize it as battery problem. But with each reset the % battery remaining shown are random. Some times it reduces exponentially, some times it increases by 40-50%.
My present ron is "SumitsVanillaManilaUltimate_v3.1.1_OldGene"

As you already done battery calibration, I guess you need test your device with another battery.

id rather suggest you to try something different.
1) charge your device to 100%
2) download my W.M.6.1 V.4.1 Pro series rom.And read the instructions in it throughly.
3) flash the rom and see your performance.
4) my W.M.6.5 Ultimate V7 you used included maximum of the HTC MEGA packages, that is the reason it was consuming more RAM.
5) My W.M.6.1 Pro series rom will provide you the best W.M 6.1 experience on GENE.
6) you wont be facing any switch off problems at all.
7) id suggest you to checkout your charger and battery too if you are facing frequent battery issues.
i hope this will help.

@ Ramersonw : Thank you for your reply. But i am the only one in my circle with this phone. So checking with another battery is not possible. Otherwise i will have to spend for a new battery just for the sake of testing this !!!
@ Karan : Thanks karan. i will try out this rom & let u know the results.

Jerin

Hey karan,
I tried ur Rom , Got to say.. Its very impressive. I loved it.
But still my phone continue to show all the problems mentioned above.

[WP7] The two ways by which you can get awesome battery

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.
(google tom xap deployer, registry editor xap for wp7 hd2, chevron unlocker)

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

i think moonlight is good at battery back up .... more than 24 hours used now ...

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

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

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.

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.

(Q) Bluetooth not working and battery dies after 4 hours

Hi!
Long time ago since I was last here but now I'm back and I have a new Windows Phone (last version I used was 6.1).
Love Mango first of all... Realle nice piece of software Using Yuki build 7720 with newest update from Microsoft BUT I still have 2 major problems:
1. My bluetooth wont turn on! It searches for devices for 5 seconds and then turns off again... None of my bluetooth headsets or my bluetooth keyboard will get recognised
2. The battery dies after 4 hours of ligt use - IE no mail sync, low light on screen, no GPS, no Wifi, no BT and still it sucks!
I'm thinking some sort of problem with the radio (using newest version 2.15) but I am not sure! Any ideas? :S
Thanks in advance!

I'm now on 2.51T and battery is good in some ways. You should try trick to solve your battery problem, e.g: http://forum.xda-developers.com/showthread.php?t=1303294
This is the best wifi and bluetooth fix for now http://xboxmod.sylvester20007.com/cabs/tweak/LEO/ (look into WIFI_PLUS)

Thanks for the reply! What are you refering to by saying 2.51T? Is that your radio version?
In regards to the BT issue... What file are you linking to? What does it do?
Lastly I have another question: Is it not possible to share your internetconnection on windows phone? I could easily do that on my old Nokia but this one lacks the funktion

Please post questions in correct section.

Sorry about that - Realised my error a little to late Thanks for moving it!

Ok took the chance and installed the BT update you linked me to - Works like a charm!! Thank you sooo much!
The other problems I still have - Those are NOT yet fixed... But yay one down at least!
Btw is there a fix that makes the buttons underneath the screen light up while the screen is on? Right now they only light up when I push them!

Sorry 5.51T(exactly 5.51T.09.29a_22.32.50.10U - for lastest Radio http://forum.xda-developers.com/showthread.php?t=1287070) is my Radio ROM, with light use(Gmail and hotmail 1 hour interval check, facebook, games and web surfing) my HD2 can last 15 hours. I posted a link about trick to solve battery drain at #2 post, you can check it out.
Are you talikng about 5 buttons at the bottom of the screen? I don't know how to make its light on when you don't press, i got used to no light on it
In some ways, I think Yuki's Mango ROM is not good at battery, you should try HD2O's one and don't forget to upgrade your Radio, you'll get some changes.

Battery life issues are almost always related to SD card. You may have an SD card that seems to be working fine, but it's actually causing massive battery drain. There are a few things you need to do to make sure your battery drain is optimal.
1 - Install HTC Battery Tool:
http://forum.xda-developers.com/showpost.php?p=19048691&postcount=19
2 - Do the "camera trick" - start WP7 > turn on camera > press icon to switch to video > wait for auto focus to happen > exit
3 - With wifi and bluetooth turned off, scroll to and select Battery Tool app > lock your screen or allow it to auto lock > a few minutes later, unlock screen and wait for battery tool to refresh. These should be your idle time discharge numbers. Battery Current should be between -4 and -10. If not, make sure you did camera trick and that you've exited the camera... that you don't have anything multitasking. Make sure BT is disabled. It causes -70 drain for me, so I only enable it when I need it.
If you cannot achieve an idle time battery current of less than -10, then it's most likely your SD card. I had a "perfectly" functioning Kingston 8GB c2, but could only get about 6 hours battery life with minimal usage. The current was -200 or greater at its best. I changed to PNY 16GB c4 and my battery current normalized immediately. This was confirmed over several reflashes and hard resets using both cards.
Good luck!

Hi!
I am using a Sandisk Class 4 16 gig card... Should be the best according to the web but I have no idea!

It's a xap. You have to download the WP7 SDK toolkit and use the Application Installer program while Zune is running and while your device does not have the lock screen active.
Problem may still be your SD card. Different batches, different issues. Until you try another card, you'll never know.

Is there a sdk for XP users also? The one on MS's homepage was only for Win 7

Just to be sure.

You say, Exit, as in using the back button to close the camera right?
What if you want to use the camera? - Should you reapply this trick or?
Regards Lars Mortensen

You only need yo do the camera trick once, each time you power on the device. It has no impact on future use of the camera and does not need to be running the background. It's a glitch pretty much, that helps us get around poor battery life.

YES IT IS. but your Windows Xp must be SP3.
Solution 1:
Requirement: WP7 SDK, here is the link http://download.microsoft.com/download/6/0/9/6092A6EA-8638-4F4B-BD49-4A8FF77B2E99/WPDT_RTM_en1.iso
Let's do it:
1, Extract WPDT_RTM_en1.iso(using winrar) then search for "baseline.dat"
2, Open "baseline.dat" with Notepad. Now, you can press Ctrl+F(search function) to search for "[gencomp7788]" string.
3, Look below string we've searched, you can see "'InstallOnLHS=1" and "InstallOnWinXP=1". Change 1 to 0
4, Save and close "baseline.dat"
5, Run setup.exe
During the installation, you will see error like "Winphone Emulator ....". Ignore it
Solution 2:
Try this mini SDK http://forum.xda-developers.com/showthread.php?t=1265846
NOTE: I don't have any Windows XP computer here so that's best I can do for you.
Good luck!

Perfect! Will have a look later on (and look at radio 2.12 also) and report back! This phone will soon be usable
One more thing... Is it a problem that there are no drivers for the compass? I would like to run Navigon software on the phone but as the compass does not work I am wondering if that is a problem?
/Anders

Btw if I install the reg editor I have seen posted somewhere else will I then be able to fix the problem that the sound is very loud regardless of how high I have turned up the volume? For example when I end a call the phone makes 3 loud "beep" sounds but the sound is turned all the way down! If I play a game it does not matter wether I have the sound turned to 1 or 5 - it's the same!
/Anders

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

You should not need chevron to unlock, as the ROM is developer(=chevron) unlocked by default. see http://forum.xda-developers.com/showpost.php?p=19058358&postcount=3974

[Q] Battery Drain VS Rom?

I know theres alot of topics about battery drain, and some methods have worked for some, but I am still stuck in the loop.
I'm using Back to the Future (XBmod-Yuki/7740) - and have tried The Camera Trick, 2.12 Radio, and Registry tweak (battery indicator) and all have failed, i get around 8-10 hours battey on minimal use, (Facebook app for 30min and 8/9 text msgs) [note: 3g and Data on]
and I was wondering is anyone noticing any difference on other wp7 roms? or is that rom specific?
Thanks in advance

Apparently i've got the same issue as you, I got 3 hours off it with intensive use today ( 2.12 radio, no battery fix, but it was draned down to zero )
I'm also using the back to the future rom ( But it's registered as 7720 )
My device is eastern europeian.

I'm back on winmo
i will try wp7 again (HD2O) (7740) but with different SD cards, hopefully i get a lil better life
ill let you knw how that goes

and so far used 10hours
and still 54% battery remaining
3g and data is ON!
Location OFF
Live Tiles disables (have to manually update hotmail etc, no push)
Tooks round 40pics, used FB app (Biggest drain)
and few small video clips (2.mins each)
also 70-100 txts snt and recieved
im happy now

yeah i was struggling with battery life for a while too.
the camera trick seems to have helped a lot. i get almost 2 days with normal use with location, 3g and data all turned off. i am going to do the registry trick, then turn location, 3g and data back on to see if anything changes.
EDIT: the registry editor that works with mango does not allow me access to these registry files. oh well.

Android SD was still not the best I've tried. while the ROM had more battery life then yuki's back to the future, it still left me 30 minutes before I was ready to let it go.
Today on WP7 i got 3.5 hours with: the camera trick,(Switch to video and leave it running, right?) also no 3g no Wi-Fi and no Location/Bluetooth. Brightness all the way down ( snowy weather ) . Where can I find the instructions/guide to installing pdaimatejam's or is it included in the download?

Do we have to use camera trick every time we reboot HD2? How about the reset command from MDLDR menu? Do we need use it every time we replace battery?

reboot should be fine, bt i tried the HD20 rom over last few days (radio 2.15) and battery drain whilst standby is AMAZING! with 3g on over night it drained like 5-7% battery, but when using browser, whats app etc battery drains too much :S
