[HD2 Windows Mobile 6.5 ROM Development] dutch64:
I never use the ereader and doc tab, if they are in the rom i disable them and run the cab in this thread to disable those services like indexing etc

In the topix rom, also because it is base 1.66 i believe, i was able to go back to radio 2.06.51.07 which also makes a huge difference i think.

I believe it's a combination of things, like mentioned, a corrupt mp3 or doc, indexing services, base version of rom (and so a difference in drivers) and radio version used.

All i can say for me is that a base 1.66 rom with matching radio seems to have the most impact, about 2-2.5% drain per hour including live mail setting "as items arrive". That's extremely good i think
[HD2 Windows Mobile 6.5 ROM Development] dutch64:
I tested all roms with exactly same data on SD card, some mp3, some software and no docs

base 2.10 6.5.x roms and 207 or 208 radio all about 7-11 % per hour

base 2.10 6.5 roms, same radio, about 4-5% per hour

base 1.66 rom with 206 radio, about 2-2.5 % Same software installed, same SD card, same usage.

Seems for everyone it's a bit different:)
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Thanks dutch64 for the review.

As mentioned, is a combination between MP3, indexing doc's... produce the battery drain. In my case, solved just with the .cab posted here.

Now I'm under a 6.5.5. ROM with Radio v2.08XXX_2 and battery consumption in a stand by mode is about 3% per hour.
[HD2 Windows Mobile 6.5 ROM Development] .hide:
Ok finally finished 19pages of reading. and gotta share my battery consumption and guys please help me out to see if it adnormal battery usage

On dutty 2.3 WWE rom and radio info on my siggy

fully charge at around 1600 and had a 1 hour and 30mins phone call ,3 text in and out, 10 mins of Msn and few hours of playing around with .cab file and setting etc. with around 45mins of sync(without charging). about 10mins of wifi/3G connection and around 4 hours of sleep mode

During the 1 hours and 30mins phone call my battery drop around 10-12% and sleep mode for around 8 hours it drop approximately 8-10% (the day before i tested) so total of idiling in sleep mode and playing around with this device i now left with 12% battery life. over 12 hours i loss 88% without wifi/3G. is this consider battery drain ? and i notice the 1st 10% drain extreme fast ,anyone notice it too?

during the 1st 2 days of flashing the battery consumption is really insane enough. Around 1% per 1-2mins of just pressing around without sync /3G etc , just pure playing around. its really pathetic

thanks for reading. and hope guys outhere able to tell me if my battery consumption is normal or draining. because my prevoius phone is a N95 8gb with have a good battery usage. so need help from pundit here thanks!
[HD2 Windows Mobile 6.5 ROM Development] sternas:
My suggestion (if this problem really exists) is:

1) Flash with Original ROM 1.48

2) Format (full) your SD card with PC

3) Use SSPL to flash a custom ROM.
[HD2 Windows Mobile 6.5 ROM Development] mietekxxx:
If you have read my previous posts, I always flash Original 1.48 in between other flashes. I'm using 2GB card which was delivered with phone (nothing more on in besides LEOIMG.nbh), 'cause flasher doesn't work with 16GB one. And, I've tried HSPL and SSPL in many configurations, all described before.

Today I've tried new Original 1.66. Works fine, based on current usage I can guess that battery will last more than 24h. After first flash of 1.66 and making sure everything is ok, I've flashed Dutty's HG v0.5 - nothing new, -1% every ~2 minutes. So back to 1.66 for now, during weekend I'll run BattLog with bot ROMs. For how long this program should be running to make sufficient log?

p.s.

Glad to see, I'm not the only one with this problem. This probably rules out any hardware problem.
[HD2 Windows Mobile 6.5 ROM Development] mietekxxx:
Here's some news from BattLog. With original ROM 1.66 battery usage varies from -170mA to -308mA when screen is on, sms is transferred, etc. [no bluetooth or wifi, just 3G], and lowers to -4mA in suspend [screen off, no data connection, 3G network].

Now with Dutty's HG 0.5 it also varies between -190mA to even -330mA when I'm using the phone. But after turning off the screen it didn't go to 4ma but stayed around 190~200(!). Again without data connection, bluetooth or wifi, just plain 3G. So first thing, I've turned off 3G - still around -200mA. Then went to airplain mode, also didn't help. And according to Task Manager, CPU usage is at minimum level [mostly 0%].

OK. So we know, it's not related to network/radio. Or it so deep, it stays on in airplain mode. If that is even possible, I don't know. And it's not CPU that eats all that extra 200mA. What else can I turn off? How to identify this power-eater? Any ideas?

p.s.

New idea. Maybe CPU isn't scaling down in suspend mode? It should lower frequency, right? I'm just guessing...
[HD2 Windows Mobile 6.5 ROM Development] pdukanac:
i am using the same duttys rom and have no problems , battery lasts 1-2 days depending on usage = same as with stock rom

for some reason device doesnt go in standby mode , its something with your configuration and/or software installed
[HD2 Windows Mobile 6.5 ROM Development] chris_ah1:
I dont see why it would be config/software if he is flashing a clean ROM?
[HD2 Windows Mobile 6.5 ROM Development] mikgangal:
had the exact same problem..solved?

i know exactly what u've been going through..super fast battery drain with no apparent reason.

in the same time i was getting extremly laggy phone..but kinda at random times..hard to explain.

untill i removed the flash card :confused:...and the next day my phone ran waay longer than the stock rom ever did. when i put the card back in...phone getting warm, laggy and super fast battery drain.

so i formatted my card ..everything ok...copied back all the programs ..laggy and warm again...

eventually i copied one program at a time back to the sdcard...(except some that should run only from the phone)..and for now everything seems ok..

and by the way..the battery program is pretty cool..i managed to graph in excel my power consumption...coupled with gprofile that turns my phone off while at work...power lasts super long.

SO JUST TRY PLAYING WITH U'RE SD CARD might be the solution...

explanation..i have none, but it worked for me
[HD2 Windows Mobile 6.5 ROM Development] mietekxxx:
You were right!

Why the hell I didn't think about it. It was the only thing that I didn't change through all those days... After removing card everything went back to normal, -4mA with screen off. Now I've cleared whole card and recovering folders in order to find faulty one.

I'll write as soon as I'll find it. But problem seems to be solved. At least :D I owe you one.

--update:

Found it. It was folder in /Storage Card/My documents with about 40 ebooks [mostly .doc, few .rtf and .pdf]. Maybe it was manila document tab that was trying to render them [some of them have few hundred pages], but if so, why Task Manager didn't show high CPU usage? Original ROMs 1.48 and 1.66 don't have document tab, so this makes sense. Nevertheless, after removing whole folder everything works as it should. Thanks again mikgangal for the tip.
[HD2 Windows Mobile 6.5 ROM Development] mikgangal:
hum..the document tab makes perfect sense...since it didn't show correctly all my files..probabily it was trying to open them all this long..

for a while i thaught too i screwed up my hd2 (christmas present from gf:rolleyes:)..but it was just another software glitch:)
[HD2 Windows Mobile 6.5 ROM Development] le_paulo:
Can you post this on the tips thread? It's an excellent find that should be floated up as a possible solution to consider if someone's having battery problems...
[HD2 Windows Mobile 6.5 ROM Development] oalex:
I second that. Its an incredibly great find and might save a few folks from unnecessary headaches. Also it makes a lot of sense.

It has to be posted in sticky tip and tricks, with bold letter.

[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Brrrrrrrrrrrrrrrr, I'm going to be crazy, suddenly I found this treat.

Still having the same problem here and don't understand how to solve.

Battery drain 2 minutes=1%:eek:

I'm using a 16Gb micro sd, just formated and re-formated form PC and device

with http:

//www.sdcard.org/consumers/formatter_3/eula/

I can't enjoy my device with this situation, any help would be great.

Thanks a lot in advance.
[HD2 Windows Mobile 6.5 ROM Development] v-b-n:
Did you follow the above posts to check for document files that may be huge in size on your card. Also, what rom are you using ? Does it have the doc and reader tabs ?

I am on stock 1.66 SEA and easily get 2 days with normal usage including movie and multimedia. Custom Roms just didnt give me the batt life.
[HD2 Windows Mobile 6.5 ROM Development] zenkinz:
if the sd card is causing the battery drain, see if you have disable power management for sd card.

I realised that there's two power mgt setting for sd card, one default one, and another one for high capacity one, which I believe is for 4G and above.

so if you check hklm\drivers\sdcard\clientdrivers\classes\SDMemory_Class\High_Capacity, and the "DisablePowerManagement" is set to 1, you may want to change it to 0, to see if there's any improvement.
[HD2 Windows Mobile 6.5 ROM Development] vysus:
Back to stock ROM didn't helped me, battery drain keeps on being unbearable.

Just performed the above HKML tweak, I'll report as well
[HD2 Windows Mobile 6.5 ROM Development] giodesi1965:
Dear Vysus, I think the only solution for you is to buy a spare battery :D :D
[HD2 Windows Mobile 6.5 ROM Development] vysus:
Or to install a ROM showing the battery % like the ones you love, my dear :D
[HD2 Windows Mobile 6.5 ROM Development] giodesi1965:
....oh yeah

your Leo ...like a Vampire! :D

PS

Sorry for OT!
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Thanks a lot. Yes I followed the above post. I just have in my micro SD card the followed folders; iGO8, TT, Voices and that's all. No .pdf, no .doc.... documents 0.

My ROM is MaesusLeo_28232_V1.6Max and radio 2.08 (recommend radio by Chef) and the ROM has the doc and reader tabs.

Tonight, I change to an original ROM 1.66 without the doc and reader tabs and fantastic, just 4% consumption in stand by mode.
[HD2 Windows Mobile 6.5 ROM Development] The_Steph:
To follow cidriver, after tests, I do think it is clear that having having in your rom Sense 2.5 Doc tab is an major factor in battery consumption (even if disabled).
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Every 3 minutes I drop 1% battery. I have unchecked in the home screen tab reader, footprints, recent documents and twitter. My microSD is inside with lots of word, pdf, power point... documents. also iGO8, TomTom applications and maps, music. This folders and documents was carrying from years and in a lot of different devices...

Brrrrrrrrrrrrr, I'm so unhappy to prove a lot of things, installing new ROM and at the moment do not find the right solution.

At least for me, the real solution is not take out the heavy documents from my microsd card.

The only real solution is find a ROM without recent documents, tab reader, so I talking about the original ROM 1.66 for example.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Done, let me see if I notice any improvement, thanks a lot for your help.

After registry change and SR the device still dropping 1% every 3 minutes. Brrrrrrrrrrr. I can't hand it, go back to official one.
[HD2 Windows Mobile 6.5 ROM Development] vysus:
OK, stock ROM 1.66 ITA, I've applied that tweak over two hours ago, full charged battery.

Connection always on so all HTC services on, some e-mails sent & received, 1 call, several RSS received, in this moment 2.15 h have passed, battery is 81%.

I can say that before the report was 1% drain per two minutes.

But there's still something strange that keep holding on....
[HD2 Windows Mobile 6.5 ROM Development] zenkinz:
pretty sure it's more than just your sd card. I have monitored my own device (with my own cooked rom of course), and on average, it's about 1% drop every 30-60 mins (depending on my usage)

for e.g. at 12pm this afternoon, my battery level is 88%. Now, at 11pm, my battery level has dropped to 74%. Quite normal in my opinion, even though it's not a heavy usage in between.
[HD2 Windows Mobile 6.5 ROM Development] zenkinz:
why don't you untick these two tabs, surely with the two tabs opted out, the respective 'engine' will not be running..
[HD2 Windows Mobile 6.5 ROM Development] poo1009:
I also the one who has battery drainage problem with new series of ROM that contain document tab.

I always take document tab out because it is useless for me, consume time to load preview and it is not priority to bring it on SENSE. I also have a lot of my work PDF file in my card.

However, battery still drop like crazy. I thought that the document tab still working in background just not show, if the source of problem come from it.

I can know everytime when I flash new ROM, which ROM consume battery like crazy, by put my Leo in my pocket. The problem ROM will make my Leo Warm all time!!
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
You are right, with original ROM I monitored my device and it's about 1 or 2% drop every 30 minutes on stand by mode.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
I did, and the result is absolute the same one. Still drooping a lot % of battery. My question is somebody can create a .cab in order to delete or disable this two tabs from cocked ROM?
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
I decided to go back to original ROM 1.66 till find a solution.

At least for me the solution is not take of my heavy documents from my microSD card. It come always with me. That's why I bought a 16Gb microSD card, to carry all my documents with me, music...
[HD2 Windows Mobile 6.5 ROM Development] vysus:
Now I'm pretty sure the drainage is up to H3G ITA.

This provider sets the PDP contest always on per default.

The continuos data traffic sucks the battery in that horrible way!

Last but not least, all cookers are realizing that the 576 RAM is not so good for our european/asiatic devices and base ROM 2.0x used for brand new ones represents another possible cause....
[HD2 Windows Mobile 6.5 ROM Development] chris_ah1:
Well I did two tests:

A:

Direct push: on automatic sync

Weather: 2hours

Stocks: 30mins

1hour wifi-router browsing

30mins 3G browsing.

5mins youtube video.

1hour calls+

10texts

general fiddling with phone, some calendar use etc.

8am to 23:00: 87% used in 15hours.

B:

Outlook: every 15mins (push disabled)

Weather: 3hours

Stocks: 30mins

sms: 10 texts

calls: 20mins

Quick calendar use.

15mins browsing.

12pm to 21:00 (9hours): 17%.

12pm to 23:00 (11 hours): 19% used.

So sitting idle WITH syncs on over hsdpa I get approx 1% per hour drain.

In contrast: using the iphone 3GS somewhere inbetween A and B on the vodafone Greece network I only got 5 to 6hours of runtime although that was closer to A's use than B.

Rom: 1.48 stock.

Radio: 2.07.51_05

Network: 02 UK set to 3G auto.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Sure, this is a normal battery consumption. Now I'm testing a ROM who is going to see the light here in xda site and with my micro SD "eat" every 3 minutes 1% battery. Well I take out my micro SD and the consumption is normal.

I'm pretty sure the main problem is with documents tab, I have it disable but there is something still working.

Still working to find the way to solve the problem, maybe in the registry...
[HD2 Windows Mobile 6.5 ROM Development] chris_ah1:
yeah, i just gave it as comparison. I think my batt consumption is still half yours in 'locked'/'standby' (as it is not really in standby but still syncs).

That is from when you said 1 or 2% every 30mins whereas i get about 1%ph.

I also have 16GB microsd card - and big docs, but no ereader app, just adobe+mobipocket.
[HD2 Windows Mobile 6.5 ROM Development] cgrec92:
i too have this battery draining issue

i dont think its only documents as i have none on my sd card

could be photos or music?

i have deleted a folder called notes and inbox which are made by the system, to see if that makes a diff
[HD2 Windows Mobile 6.5 ROM Development] osash2000:
+1

the same issue is here.......however my problem is mostly due to the documents tab,,,solved by using ROM without that tab:D
[HD2 Windows Mobile 6.5 ROM Development] HTCHD2_2010:
Hi Guys,

Thanks for your hard work in investigating battery drainage. I will

try this.

I have similar but not draining every 1 min but definitely 5 times faster

than when i first had it.
[HD2 Windows Mobile 6.5 ROM Development] HTCHD2_2010:
Yeah , I agree with you something i too feel is not right still!

It should not be 19% for 2.15h.

My old Atom 02 XDA is much better and it is like 4 yrs old technology .

Common HTC please help us !!!
[HD2 Windows Mobile 6.5 ROM Development] HTCHD2_2010:
I also applied this registry change and do see noticeable improvement

in the battery drainage but haven't got concrete evident yet.

I will keep on trying to find a way to improve this or search the forum

to see if any master chef or genius has found a solution.
[HD2 Windows Mobile 6.5 ROM Development] Laurentius26:
Hi people,

If you like to find what's causing it I think people who complain here

about the battery drain should give the following info:

What size of storage card are you using?

What rom did you flash (is it t-Mob 2.x or HTC 1.x based)?

Is it a 576mb ram enable rom?

What radio do you use?

Did you use MTTY (task 29) in past (Requested by Appelflap in next post)

Btw I have another request (can you please remove temporary your mp3 from storage card and test battery)?

If everyone post this info you can compair with each other and find the cause. :rolleyes:

So please a small list with these request at the bottum of your post. ;)

Another thing you could do is flash stock T-Mob rom and see if you still have battery drain,

then you are sure if it's a cooked rom that's causing it or not.

And last thing you can try (if you still have battery drain with T-Mob stock) is flash a stock HTC rom and verify.

Good luck.

Grtz Leo :)
[HD2 Windows Mobile 6.5 ROM Development] appelflap:
Hi, just my little contribution: I always have battery drain problems when I flash a new rom these days :)

And it always disappears when I do a mtty 29 task before flashing.

Now, I am beginning to wonder if the problems didn't occur because I used mtty in the first place. So, I like to know from the people that have severe battery drain problems if they have ever used MTTY ..

(Just to exclude some possible diagnosis)
[HD2 Windows Mobile 6.5 ROM Development] The_Steph:
guys,

As far as my tests shown me:

- Sense Document tab engine is the key. Even with Document tab deactivated, the engine is working. But to achieve in draining battery, SD Card has to be present as it creates (and probably updates extremely frequently), %SDCARD%\Application Data folder.

- MTTY is not involved in this process as I had the same battery drainage before and after I did an MTTY format of my HD2 internal memory.

- Radio is also not involved as I tested almost every radio ROM available without noticeable change.

As final argument, using itje Touch-IT BL ROM gave my Leo extra battery life simply because it is using Leo 1.66 software. Using any ROM that has Leo 2.x software (that includes Document engine) litteraly eats HD2 battery.

Hope it helps...
[HD2 Windows Mobile 6.5 ROM Development] Laurentius26:
Hi,

A user in my rom thread was having battery drain (solved now!).

Yesterday he found out that it was a corrupted mp3 on his (16gb) storage card causing the battery drain.

So it's not the document engine cause I'm using it in my V2 rom. ;)

My rom has 1.66 oemdrivers and 2.10 Extended packages.

Grtz Leo :)
[HD2 Windows Mobile 6.5 ROM Development] zephyr:
Hi, I'm one of people who's concern about battery drain issue here, and I was wondering how you can make sure all of your MP3 files are not corrupted? Would Windows' disk error-checking function can spot it, or is there any app to find corrupted MP3 file?

I sometimes use normalisation software which update MP3 - and Windows Media Player can't play some of them whereas Classic Media Player (comes with K-Light codes package) can play without any problem....
[HD2 Windows Mobile 6.5 ROM Development] peterkef:
I was the guy with the corrupted MP3 on the storage card.

I use a 16G Microsd and have a lot of songs and documents on it. I never had battery drain and suddenly it came?

I did reformat the sd, flashed rom's with using MTTY, 2 hardreset's after without any improvement.

I even bought a new micro sd. Did not brought any improvement.

I did copy my files from a backup from the microsd back to the new card and the problem started again.

When I took out the sd: no battery drain.

so I removed all my MP3 and the problem was gone. Then I checked all MP3 and some of them did not play.+9

I did remove them from the SD and this night 2% drop so this is perfect.

Firts I tought the document tab was involved but this is working fine now without any drain.

So check your SD on corruption: MP3, program files, pictures.

First I did not believe this but I experianced myself.

I have great battery live now.

I did check by copying the MP3 from 1 sd to an other and when the process stopped unexpected on a certain MP3 I removed it.

When copy was ok and no stops: problem was gone.I still have around 1000MP3 on my card but no drain anymore.

Let me know if anyone needs more info.
[HD2 Windows Mobile 6.5 ROM Development] Laurentius26:
Thanks Peter for confirm.

Hopefully other users can do benefit with this.

Grtz Leo
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Peter and Leo, thanks a lot for this useful information. But how can I check for the corrupt MP3 or document?

Thanks a lot to share it.
[HD2 Windows Mobile 6.5 ROM Development] Laurentius26:
I don't have experience with this as I don't have a 16gig storage card and neither battery drain.

But I would start with removing all mp3's from storage card temporarily to verify if battery drain is gone. ;)

As battery drain is gone you could place them back by album untill you found the corrupted mp3.

Just like Peter suggest in previous post.

Grtz Leo :)
[HD2 Windows Mobile 6.5 ROM Development] appelflap:
Also, and that is what i am going to do, one can remove the storage card for a day or so and see what that will do.

(this way you can test 2 hypotheses a once, the mp3 hypohesis and

the document tab hypothesis). If there's still battery drain... oh well you know what i mean.
[HD2 Windows Mobile 6.5 ROM Development] cidriver:
Leo; I'll do it, for sure.
[HD2 Windows Mobile 6.5 ROM Development] peterkef:
Battery drain

1 more thing:

remove also the program folder from your sd card after a flash and install them again. But really remove it.

Many people make shortcuts to programtab but after a flash reinstall the program.

if you don't do this then this can give also battery drain.
[HD2 Windows Mobile 6.5 ROM Development] peterkef:
In the beginning I thought the same but I have a lot of documents on my storage and I'm not experiencing drain anymore.

Also after a rom flash: delete the data folder on the storage card. It will add and not delete the previous data. result: drain because your phone gets confused...;)
[HD2 Windows Mobile 6.5 ROM Development] appelflap:
Peter can you elaborate on this a bit more. What did you exactly do to check your mp3's. Just copying them around?
[HD2 Windows Mobile 6.5 ROM Development] manuel_f2003:
