Hi Appelflap,

I copied them from one sd to another. Using adapters on 2 USB ports.

Then I had 3 times that the copying stopped because a MP3 could not be copied (reason: not right format,....). I deleted these MP3 and the problem was gone.

I noticed before that some songs didnot play or were skipped. These I deleted also.

I did the same with pictures and the copying stopped also 2 times. I deleted these files also.

I hope this helps.
[HD2 Windows Mobile 6.5 ROM Development] zephyr:
Hi Peter, thank you very much for your post. It really lit up what could went wrong. When you say it didn't play, is it by Windows Media Player? Then I do have those MP3s as a result of nomalising (I use MP3Gain http://mp3gain.sourceforge.net/ ). Maybe I should check all through MP3 files and re-encode them again if they are not played properly. :(
[HD2 Windows Mobile 6.5 ROM Development] HTCHD2_2010:
I do experience extreme drainage when i was on Dutty Rom base 2.10.

I have 16G card and I do MTTY task 29 each time before flashing new ROM.

But when i go back to Dutty Rom base 1.66 v2.x on 27 Feb, the battery seems

to be much better but still i feel it is 30% inefficient. I compare this with

the original HTC ROM before I started flashing other ROMs.

I know for sure that my SD card has exact same content (100mp3, docs etc)

I got some info from this thread by modified the registry for SD card by turning off power mgnt for high capacity card.

This certainly improved a lot.

So now i am running Dutty base 1.66 ROM v2.x with registry mod, battery

life is 90% better.

So you should seriously consider to give this a try if other suggestions fail.

Laurentius26: You mentioned corrupted MP3 file, could there be a correlation

between this SD power mgnt registry setting and file corruption?

I meant like if there is a power mgnt background process which scan the SD card and get stuck on corrupted files times out then repeatedly try again, as

a result cause lot of CPU cycles leading to battery draining?

Well just thought i throw it out there.
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
this is a very good thread, lots of progress being made, is there any chance someone could put the registry tweak into a cab seeing as i don't have a registry editor? this would be much appreciated

thanks in advance
[HD2 Windows Mobile 6.5 ROM Development] The_Steph:
Laurentius26 and peterkef,

Thanks for all your information. I may have been mislead by my tests. As I type I am currently removing all music MP3s on my Storage Card and guess what, I just realised which MP3 is probably causing so much trouble to me. One WMA file I converted to MP3 to warn me when email or SMS is received and that is not sounding as expected at all.

Maybe the solution to my problems is at one MP3 to me ;o)

Let's try during the complete week-end. I'll let you know after the week-end.
[HD2 Windows Mobile 6.5 ROM Development] appelflap:
Thanks. I definitely going to try that. Just to clean up my files (maybe it speeds up the indexing processes as well)

Unfortunately it isn't my Storage Card. I've removed it for a half a day and still a excessive drain. But thanks for the tip anyway.
[HD2 Windows Mobile 6.5 ROM Development] appelflap:
:) I am experimenting with that radio right now. I downgraded from a 2.08 radio and I thought it would solve my problem. Njet ...

Which radio are you using now?
[HD2 Windows Mobile 6.5 ROM Development] appelflap:
Thanks for the tip.

One quick question though. Of course it is hard to remember, but when did your excessive battery drain problems began. Was it after the first time you used mtty?

(again i'm just trying to exclude a hypothesis here. No attack on mtty... )
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
ok guys ive done the registry tweak, ive formatted my memory card and readded files to the memory card, there werent any corrupt files.

ive only got 8% battery left so ill post back tomorrow with my results after a full charge
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
I do not have any music, delete the programs file folder form my microSD and I was testing the hole radios... I'm so furious...

Two days without a microSD in order to test a ROM who is going to see the light here very soon.

My next step, take out all the documents form microSD too. My God!!!!!
[HD2 Windows Mobile 6.5 ROM Development] zenkinz:
some folks who are using my ROM reported a better battery consumption when using 2.07.50.27 so you might want to try it.
[HD2 Windows Mobile 6.5 ROM Development] Laurentius26:
Hi Cidriver,

So what you are saying is that you even have battery drain without the storage card inserted?
[HD2 Windows Mobile 6.5 ROM Development] peterkef:
I know it is a lot of work but my battery is great now.

2% overnight and during the day 55% loss in 8 hours with heavy ise. phonecalls, sms, pushmail and internet all the time.

so for me it was worthwhile.

did you delete the data folder on the sd?

good luck
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Leo, sorry for my English, and the way to explain my problem.

I have no battery drain without microSd inserted.

The problem starts always as soon as insert the 16 GB microSD

// probably time between checking battery status, it's 10s by default, changed it to 20s

all these tweaks do is enable the hidden power management settings for communications and hard drives etc, these have made a very big difference in my opinion

although these tweaks help a lot, there is still a problem with some sort of memory leakage which is being discussed in this thread, this still needs to be solved. These tweaks just help out in the mean time :)

keep up the good work we'll get there!
[HD2 Windows Mobile 6.5 ROM Development] sardelisp:
thanks for the registry tweaks!!!

I have applyed them and post if any improvement come out..

I have also one question to the chefs!

Is there any way to disable all those engines document engine that searches for documents and music library that searches mp3s??

Can we disable them somehow?or make them search less frequently?
[HD2 Windows Mobile 6.5 ROM Development] Laurentius26:
No problem but this confirms it's a storage card issue and not a rom issue to my opinion. ;)

I don't want to anoy you but I think formatting your sd is best thing you can do to verify if you still have battery drain. :o
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Yes it is a storage card problem.

Storage card were formatted twice, now I have just iGO8 and TT maps none documents.:eek:
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
i have formatted the sd card twice - still battery drain

i have changed rom from duttys to artemis - still battery drain

any ideas?
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
I do not have a poll interval option. why not?
[HD2 Windows Mobile 6.5 ROM Development] snipey:
This problem is easily fixed by using mtty task 29 before flashing the room. MTTY is sticky in rom section.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Snipey; every time I flash a new ROM I use MTTY, and believe me, no way:(

I have 0 problem when I flash onto a official ROM. No mp3, no big documents or other issues on my microSD card problem is present. So, my question is, there is something wrong with recent documents, reader... But on a cookeed ROM everything is going fine if I used it without microSD card, estrange yes? I'm in the same place Brrrrrrrrrrrrrrrrrrrrrrrrr!!!!!

Thanks to all to be involved and share your impressions.
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
Is it possible to build a cab that totally REMOVES the documents tab and service entirely, so as to eliminate the potentiality of this issue?
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
At the present time I didn't find it.

The only way is flashing an official ROM that no doesn't have the tab you mentioned and of course, without any problem.
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
can anyone provide an example of what they would consider normal battery drain patterns in typical use? I have almost no reference point because I have been using cooked ROMs since the first day I owned my HD2.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Normal battery drain

in stand by

use: 1%-2% every 30 minutes :)

Un-normal battery drain in stand by mode: 1% every 3 minutes.:eek:
[HD2 Windows Mobile 6.5 ROM Development] snipey:
Mmm, are you sure you did task 29, and not task 28? I had the same problems and that completely solved it. (start MTTY, set 14 0, task 29, task 8, flash)

Good luck, hope it helps, I know how irritating the problem is...
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
Okay that gives me some perspective thanks for the info.

So just with the display on, but no WiFi and not doing anything in particular, maybe just having GPRS connected in the background, for example updating weather about 1 time per hour, how long does it take to "normally" burn through 1% of battery?
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
for me it takes 9 hours to completely run out of battery

i know thats not right

ive disabled every single data service and lights are on 20%

any ideas?
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
But, in that 9 hours, the phone is not constantly being used, correct? I mean, it goes to sleep, etc., correct?

You are saying that, even with all the data services turned off and screen at 20%, the best you can get is typically 9 hours?!
[HD2 Windows Mobile 6.5 ROM Development] vysus:
Same here with every ROM and every provider, I've bought a brand new device, nothing changed....
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
yes thats EXACTLY what im saying and is why im praying for a fix

the phone is off 80% of the time

the most activity i ever do is half an hour music which takes away about 30%

30 mins surfing will use about 20%

the rest is just a few texts

i also use wmlonglife, this has helped give me an extra 10 mins battery life..

its not a dud battery as i have bought 2

help greatly appreciated here!
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
But are you using 3G or WiFi in this 9 hour period? I've flash a LOT of ROMs and Radio combinations, and I never get that poor of a battery performance. I can typically get 12 hours of good, solid use per day. This would include a mixture of internet, email, calls, text messaging, etc. I do not use 3G. I only use WiFi at home, and even with an hour of WiFi use, 12 hours is typical, and sometimes I can get 15 hours or more, depending on various factors.

I have a 16GB class2 card with typically 15 .pdf files, ranging from 1-400 pages each, and about 1,000 mp3 files, etc and I use a ROM with the documents tab.

If I were in your situation, I would:

Format my SD card

Run MTTY

Flash a new Radio, according to which ROM I was using.

Flash the new ROM, and hard-reset 2x before proceeding to any installations.

After, I'd keep my use of "add-ons to a minimum and try to run the ROM as close to "stock" as I could.

That has always been my approach, and it has worked for me.
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
i literally only browse for 30 mins in which 3g is enabled, other than wmlonglife turns that off after 10 seconds and is not used again

ive tried every radio and many roms now, i use mtty and perform a hard reset each time, this has not solved my issue.

i deleted all documents in my sd card as i read this could be related to battery life drain, i have 100 songs and 20 pictures. i have formatted my sd card three times to check for corrupted files and have found none.

i have no addons whatsoever, i flashed not 3 hours ago and have changed nothing apart from backlight and data services

i am clueless about what to do

thanks for your help donalgodon
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
You also said that you tried a different SD card, correct? (I thought I read that)

Man, i don't know what to tell you.... but it does sound strange... almost as if you have a hardware issue.

In standby, my HD2 doesn't even change 1% per hour. I just tested that.

I don't use the "long-life" software you mentioned. I just apply the power management tweaks mentioned in this thread (above) and used BSB tweaks "power saving" feature. That's it.

What brand and class of SD card do you use?
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
yeah i had a 8gb and a 2gb, the 8gb seems to have stopped working with my computer after a hard reset..god knows

so im now using my 2gb

ive applied the tweaks above, the bsb power saving tweak and using wmlonglife which disables connections when not needed

maybe its just me.

thanks anyway
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
The steps I made;

1. Press-hold Volume down + Power on the phone, attach USB port. Wait until "USB" text appear at bootloader screen.

2. run MTTY.exe. Wait quite a while until a config window popup. Select USB port. Enter.

3. type "set 14 0". Enter.

4. type "task 29". Enter.

5. type "task 8". Enter.

6. While the phone turns black to restart, press-hold Volume Down to boot to the SPL screen again.

7. Run LeoRUUcustom.exe from PC and install the ROM.
[HD2 Windows Mobile 6.5 ROM Development] donalgodon:
Something is definitely strange, because my HD2 with a SanDisk class 2 just reached 1.5 hours in sleep mode before dropping 1% as I just checked every few minutes and put it back to sleep.

cidriver,

Running Miri's 23544 ROM and thankfully to the registry changes (and the removal of all MP3 files on my 16 GB PNY micrSD card), I've only lost 12% in a 8 hour long night (in airplaine mode). Compared to the 50% I usually had, that's simply a factor 4 division.

Now I need to readd the MP3 files to see if it changes anything for the next night.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
I was running the last Romeo's OS Version, 23541.5.5.0 and with Manila 2.5.20121412.1, tested with 3 radio version and also with the .resgistrycab. With and disable in home screen:

Reader

Recent Documents

I made a lot of test and I'm pretty sure the problem is with Reader and Recent Documents, :confused: why I said that, simple; One of my multiples test, I did with a just formatted microSd card (so total empty) and the problem persist. :( Repeat, total empty memory card.

Now I removed the microSd card and.... surprise!!!! The device work like a charm, no battery drain. :)

In the way, when you flash onto a ROM (whatever) who do no have the mentioned Reader and Recent Documents on the home screen the battery drain is in stand by mode 1 or 2% every 30 minutes. :cool:

Again, my conclusion, the problem come from home screen with Reader and Recent Documents. :mad::mad::mad::mad::mad::mad::mad::mad::mad::mad:
[HD2 Windows Mobile 6.5 ROM Development] vysus:
OK, now I really have had enough of that f*****g battery drain, so I've applied all the above tweaks.

EDIT: 10 minutes passed and still 19%, HALLELUJAH!!!!!!!!!!
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
alright guys im not really sure what ive done but i seem to have fixed my battery life! ive even increased the backlight to 60% instead of 20%

from 8.00am to 10.20pm now im still on 65% battery with half an hour of browsing, about 50 sms, half an hour of music, about an hour of general playing around

below is what ive done:

1) applied the power management tweaks i posted above

2) installed wmlonglife - actually very useful! can be found in this forum, it simply turns off and turns on 3g/connections to what you set it as, very convenient!

3) (this seems to have done it for me) i installed bsb tweaks and enabled the power management setting

i am using artemis rom v 5.5 which has eReader

i have formatted my sd card three times - this didnt really make a difference for me

hope this helps guys!
[HD2 Windows Mobile 6.5 ROM Development] dutch64:
interesting thread, i started trying out things also and for me the major difference was whether using a 6.5 rom or 6.5.x

I've used the Energy rom as it comes in 2 flavors, 6.5 and 6.5.x. Installed on both the same things, used on both checking 2 email accounts every 30 minutes and windows live mail "as items arrive"

Automatic weather, stocks etc, all the same and even tried to make test call of same length and send same number of sms and email, this all done from the same location in my house so that reception quality would not interfere too much

the results:)

6.5.x rom, roughly about 5-10% drainage per hour

6.5 rom, roughly about 2% per hour...

I like the fingerfriendly 6.5..x interface but back to 6.5 for me now:)

No doc tab

SD Card: Nothhing in it, formated

BattLog: 1 second interval

Same Radio: 2.08.50.08_2

Same: Did not do any MTTY

then I flash my second rom: Tom leo 23544 last night

Over night (about 6 hours), battery from 100% to 96%

Have doc tab

Tbattery: 10 second interval

dwin,

Maybe tom_codon inserted power management registry settings in his ROM...

cidriver,

New test for me, I readded my MP3 files on my SD Card (except the one that expect to be faulty) and still 1.5% battery drainage each hour. It then let me two possible reasons for my problem: power management tweaks or faulty MP3. Let's see that tonight.
[HD2 Windows Mobile 6.5 ROM Development] vysus:
Possible cause

...should be Windows Live Messenger!

If some of you use Hotmail in push mode via the WL, try to disable or set "manual" or any other time interval instead of "as item arrives" and report if it helps....

Thanks MAKEVERAL, I tweak the registry, and here it is:

[HKEY_LOCAL_MACHINE\Software\HTC\Manila\HTCService]

"DocIndexerService"="ocIndexerService.dll"

"ReaderService"="xReaderService.dll"

This registry tweaks, disable your doc indexer and reader service, at least my causing drain battery.

cidriver,

After moving to new Sternas' Artemis ROM I wanted to do some new tests. Newly flashed, the battery drain started again (5% an hour with eReader and Documents tab disabled). Put the power management tweaks ang get back to a reasonable 1.5% battery use/hour (airplane mode or not). These tweaks are really a huge help.

Just seen you have a way (that seems strange to me as you insert some reg keys instead of deleting some) to disable document indexing engine. Next step is to start disabling it in order to see if I can get a 1% battery drainage a night (in airplaine mode of course) as I used to have with my "Old" Blackstone. More news to come tomorrow then.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Thank you mate, still in touch as soon as we have some new news.
