I was using for a long time the rom from QTek with version 2.18. The reason that I sticked so long to this rom is because its efficiency with the battery. As soon I updated to a newer AKU rom I experienced the same problem, in standby it drains much more battery than this QTek rom. Normal a night it costs about 1%, with the newer roms is dropped as soon as 20%. I searched for a reason and finally I found it. I removed the SD card and I saw the problem solved. So there must be something with the SD Card. I searched in the registery and found that the power management function for the SD Card driver is disabled. This means the sd card is always enabled and at full function (= full power).
If you like to enable the power management function of this driver change this key in the registery
HKLM/Drivers/SDCARD/ClientDrivers/Class/SDMemory_Class/DisablePowerManagement change this value to 0. And try then.
I use now WM6 and changed this value, now it is using less battery than the qtek rom.
Without this setting I was able to user Crossbow and newer AKU roms for MAX 48 hours. Normal (and now) it is 4 ~ 5 days or even more if I keep it more standby
Please tell me if this also works for you.
After installing the aku 3.x rom I noticed an amazing increase in battery drainage.
Checked and set the parameter as you said which did the trick.
Thanks for sharing! you really helped me out here.
Well done mkara!
I, as many others, have experienced greater battery drain with the newer ROM's as of late. I'm not sure if this is what the difference was per se...but regardless...this really has helped with battery efficiency.
Fantastic find here.
Does anybody know what enabling power management does?

I just tried it this AM and while it is too soon to really tell, it does seem to be making a difference but I would like to know if all it does is enable full access to the SD card, and exactly how it does this. I don't run programs off the card so that isn't a potential side effect but I wonder if it could be.
The powermanagement means that the driver can disable the SD card.
This is normally done when the device is in standby mode, the SD card is also shutdown.
Only what I can think what happens is that if you get the device back from standby that the sd card is not DIRECT accesible (but after a few ms).
It should not be a big deal
Power management is normally done on Wifi, LCD, CPU and many things.
WiFi is completely shutdown on standby because is not needed. LCD same thing. CPU is running on low frequency.
I didn't experience any problems. It is the same behaviour with the older 2.xx roms. If you used this roms and had no problem this should be work perfect.
My battery is now absolutely perfect running with this enabled. Even better than WM5
I noticed a big battery drain also. I have applied this workaround, and I will let you know in a few days how it worked out.
Thanks for the find!
it seems to be better for me with this reg change, but still not to the same battery life i got from AKU2. This morning it was looking really good. 30 minute phone call plus exchange mail and it only dropped to 95%
then all of a sudden it was down to 83% and is now at 68% with only maybe 5-10 minutes of voice calls since. i'll keep experimenting, but the battery life issues still seem to be there for me.

NICE !!!
I have made a cab to do it.
Hope this solves the problem...
majority of my programs are installed on the SDcard, how would this effect it? will it take a while for me to load my programs?
Well been a full day(workwise) when my device is used the most and this registry change has helped.
Thanks!
.
I just applied it to a full battery.....here's to hoping it works.....will let you guys know.
I was also plagued by this issue. Made the changes - will let you guys know if this helps too.
I made this change yesterday and this moring woke up at 7:30 to 85% battery An hour later it is down to 82% and all I did each time was switch the device on to see the clock (and battery status obviously). This is similar behaviour to when I had the 2.47 & 2.61 Radio ROMs installed, looks like I'll revert the registry setting back and see if it 'cures' itself

Hmm strange, with me it helps. Also with the Radio 2.61 rom (But I don't suspect the Radio rom). If you use batterystatus don't use the extra indicators (that update with a interval). I THINK (not sure) these indicators don't let the CPU go to standby.
I'm sure you've tried correctly this setting but you have to restart your mobile after this setting.... (After changing let the device flush the registry, about 5 a 15 sec in standby, and then soft reset).
If you want to be sure that it not the SD card, remove it if you go to sleep....
i tried this and after 12 hours with barely any use my battery was down to 59%

Reverted the registry change and this morning woke up to 98% battery
I think I'll leave it at the default of 1 for the time being until some more information becomes available.

Hi Andy,
Very Very strange indeed. I also recommend you to leave it in default setting. I use a G3 (maybe here are also differences?). I must say that I didn't test this on Faria's 3.3.0 rom because for me it is very unstable and WiFi is impossible for me on this rom. (I also don't understand it, but there are differences in the phones I think).
For me it worked on Crossbow. But it seems you don't have this problem? If you wake up and battery dropped only 2% it's nothing!. For me it dropped 20~30% just for a night standby
i made the change last night, fully charged and woke up to a DEAD PHONE
as in it wouldn't even turn on! (even though it was a full charge)
I had to pull the battery out, wait 5 minutes, put it back in, and it finally booted to 100%. i thought i lost my phone
Hi guys,
I have updated my Qtek 9090 to WM5. But I found an annoying problem, every time when I plug out the battery, for example to change the SIM card, the date information will lose and I must set it again when I turn it on.
Does anybody have good idea to solve this small problem?
BR,
Peter

What is the status of your backup battery.
Is it fully charged before AND after you change the battery.
If after changing the main battery the system reports the backup battery to be discharged, maybe your backup battery is died?
Mine does the same thing. I think our back up batteries are dead. How does one replace the battery?
the date and time gets erased every time i change batteries. quickest way to get the time/date right is to connect the xda2s to the computer via activesync (or manually correct it)
I have checked the status of the backup battery from WM5 battery information, it is 100% full. Is this information believable or not? If not, does anybody know how to change the backup battery?

What % is the backup battery after you change your main battery.
Thats the key, if it says it is flat after change then your backup battery is not holding charge.
To change it I believe would entail opening your pda case and removing the old battery & installing a new battery of the same type/rate.
Don't know if they are soldered or clipped in, someone with more knowledge may shed some light.
i use the ms activesync to synchronize the date
i have the same problem.. even if i poke the soft reset button, time and date reverts to default.. september 1, 2004..
i can assure that my back up battery still works.. it loses charge and drains (my ramdisk gets wiped out) for about 30 minutes without the main batt..
I'm having the same problem as well.
Anyone found a solution to this yet?
EDITED:
I'm using Helmi_BA_WM2k5_AKU3.5_v1.4.CF2 R2
And I've confirmed this problem doesn't occur when using WM2003SE.

I have no problem with that, and i am using the same rom as you.
When i remove teh battery, first i lock the device, and turn it off, making the screen all black. now i remove it, and in less than 20 secs i swap cards.
No mem loss.
When you mean by "turning it off", you meant pressing the power button and it goes to suspend mode right?
Cuz on my Dell X51v there's a function to perform a full poweroff which I can't find in this ROM.
anyone tried to remove the battery the moment just after choosing a soft reset?
1. choose soft reset
2. then when the four colored lines come out, take out the battery
3. insert new battery
4. turn on the power
5. just in case the R and G values display "NONE", just choose soft reset again
i think it's a good alternative to keep the date/time after changing batteries... i just don't know the harmful ramifications in doing so, if any...

Of course.
Ok, this is strange.
I accidentally moved the battery latch when the screen was on, the battery fell out and the screen faded out quickly. But when I put the battery back in and reboot the device, all settings including date & time were still there!
So I tried the same method when swapping to my other battery and it worked as well! w00tz!
Done it a few times now with 100% success so far.
Drifter
I use Drifter by Kopsis when I'm in wi-fi range. Drifter uses Network Time Protocol (NTP) to set the time. Thus you can set the time even without syncing to your computer.
I'm using AKU 3.5.2 with the BuildOS on default settings and i can change my battery just fine.
Hello all,
it seems there is more to complain about than this video driver nightmare. I'm adding two issues in separate threads. This one deals with the GPS module and resulting battery drain. I observed it right after installing the first GPS software and searched for help nearly everywhere, and I found some more hints pointing at short battery uptimes after GPS was used. Here's how it works:
- access the GPS port (GPS software, "OziExplorer" or the like)
- stop the access
- end all software tasks
- put device into standby
- Due to an additional current draw of approx. 50mA the battery will be empty within a day --- in standby. The GPS unit does _NOT_ return into a low power state, no matter how much time passed.
- Only a complete power-off or pressing the soft reset button ends this condition.
Installing a battery monitor software (BatteryStatus) confirmed an additional current draw of approx. 50mA after the mentioned GPS port access.
I found a promising registry entry HKLM/System/CurrentControlSet/GPS Intermediate Driver/Drivers/SleepOnNoData but again it does not seem to have the least of an effect (default is 1000).
HTC support claimed "they know of no issues in conjunction with the Kaiser" - well at that point I was not even able to put my question. Which somehow tells me how serious these guys take their customers .
BusterTyTN
One thing I forgot: knowing that the GPS does not turn off, I use to apply a soft reset whenever I used a GPS software. Voilá, several days runtime until I have to recharge!
this confirms my suspicion...
now and then it happend that the battery of my tytn was empty in the morning. I never really proved that it happend after using gps, and looked for a thread here....well, here it is...
Others must have made the same observation.....
Today I succeeded submitting a bug report to HTC, at last... built a test setup, made measurements with a digital scope, documented everything. The problem can always be reproduced. There is a smooth, steady state current consumption of nearly 50mA after the GPS has been used, without any software running in the background. Until you soft reset the device.
I will let you know as soon as I have news on this one. Whoever can reproduce this, please add a note to this thread. This power management issue is getting more and more interesting.
BusterTyTN
Hm i must check that in my klaaiser last days i was always instaling something so manu soft restes have been made i'll test it now.
I can confirm that GPS activation seems to drain battery more.
I have installed the latest dutty rom, and have not installed tom tom.
So far I have had the phone on for 28 hours, and still have 40% of the battery.
Previously battery would die after 12 hours.
I am not sure now I want to install Tomtom.... ;-)
But I know I will not be able to resist....
what should my kaisers power usage be at on average, mine seems very high at an average of 250mW?
Good idea. Let's take typical power measurements and state them here. I will come back with some more values later on. I do not have my scope measurements within reach, and I am going to complete the picture with the help of "BatteryStatus". Here's what comes right out of my memory:
In standby, no background software, no communications etc.: next to nothing, 0 to 1mA / 0..3mW
Active, still no software or communications, just the "today" screen, brightness at the second lowest setting: ~180mW

I'm using the Garmin software for gps, and I don't seem to have te battery drain problem. with Garmin xt running 220 - 280 ma. Once I shut down Garmin xt it slowly drops, taking from 3 to 5 minutes, back to a normal 60 -70 ma. (1 -3 ma in standby.)
Good luck sorting this out.
Typical power data
Nakel, negative proof is just as good as positive. Well possible that there is a dependency on the ROM type / branding / OEM configuration, so maybe you're so kind to add the brand / type / ROM # of your device. And perhaps you can try GPSTest and check the battery current in standby again - just to exclude nasty side effects.
My device is the "Vodafone VPA compact V", ROM Version 1.56.162.5, Radio 1.27.12.11. No updates so far. Here comes its power consumption data, taken using "BatteryStatus". I observed the power display for a few minutes in each situation and tried to catch the lowest readouts. The individual sections were activated one by one. Sorry I forgot to check the current increase at full brightness, but I think that is of secondary interest here.
1. Pstby = 0..3mW (reference for the following)
2. Pon = 155..180 mW (reference, set to lowest brightness, no task running, didnt touch screen nor buttons)
3. Pon+20mW = 175..200 mW GSM phone logged in, no calls
4. Pon+5..10mW = 160..190 mW BT on, no link
5. Pon+130..400mW = 280..560 mW WLAN, no data transfers
6. Pon+850mW = 1000 mW GPS on, SW running (OziExplorer or GPSTest), with & w/o GPS fix
7. Pon+200mW = 340 mW On, after GPS access. Same situation as 2. otherwise.
8. Pstby+180 mW = 180mW standby, after GPS access. Same situation as 1.
9. Pon+380mW = 540 mW Mediaplayer running, 0%Volume
10. Pon+530mW = 680 mW 5% volume, internal speaker
11. Pon+260mW = 410 mW, 5% volume, display completely off
Scope readouts show very little battery current ripple (clean DC) in situations 1. and 8. Significant ripple in all other modes.

I've used both Pocket Streets and Fugawi and found that, if I use the "stop" or "close" GPS option in those applications, the GPS shuts down and I have no battery drain issue.
I think you're looking at a problem with an anti-social application rather than a Kaiser issue.
I'm running the stock AT&T ROM, but have upgraded the radio to 1.27.12.17
You have to make sure you close the GPS application and not just minimize it. If you minimize the GPS app that you are running the GPS will continue to stay on, draining the battery.

Both of the applications I mentioned have features that specifically start and stop the GPS. They do not have to be closed to avoid battery drain issues.
I'll go ahead and add my numbers:
Before GPS:
Standby: <1mA
On and Active: ~85mA
GPS turned on (GPS Utilities): ~250mA Steady (450mA peak)
After terminating GPS software:
On and Active: ~80mA
Standby: <1mA

Well I already saw quite a number of complaints out there, regarding quickly drained batteries, in similar circumstances. The problem is definitely there, I only have to find out the prone devices and/or the affected versions.
So anybody who can reproduce these findings, please contribute here, and do not forget your version numbers.
Thank you all

D 1.56.00.00
I think I already wrote that in another thread on the same subject...
any road,
I had battery drain issues just twice: those times the phone completely drained the battery in a few hours... possibly more or less the 6 hours even dhob187 experienced.
I just re-charged the phone and had no more problems. I dunno why that happened but as it is not a common behaviour I'm not that worried.
In my experience I had no problems with GPS-battery relationship.
Rom: 1.56.408.5
Radio: 1.27.12.11
Protocol: 22.45.88.07H
According to MSDN the intermediate driver 'counts' the number of open connections to it. After all programs have closed their connection the driver shuts the gps down. When an program 'forgets' to close it's connection the driver doesn't shut down the driver. Could be an good idea to write an little program to check the status of the driver (with IOCTL_SERVICE_STATUS?) and/or start and stop the driver (IOCTL_SERVICE_START / IOCTL_SERVICE_STOP)
All i can tell is that the new Dutty rom Wm6.1 Beta1 is the best for your Batt. live !!!!
It's the best so far...

Hey guys,
About a week ago I started rapidly losing battery life.
I've done a bunch of research and installed task killers, OS monitors, Spare Parts, etc. I've uninstalled apps that had wake_lock and done a Reset to Factory Defaults,changed the brightness, as well as performed a recalibration for the battery (one cycle). I also turned the phone to Airplane mode since I moved offices and thought maybe that was a problem.
I am not sure why this is the problem, but I have notices through spare parts that my phone does not go to sleep. The time it gives for Time without Sleeping (under "other Usage->Last Unplugged) is typically about the same time as I have had it off the charger. The phone will not last a full day anymore (Actually I'm lucky if it's still on when I get home from work). The only program that I can think of is the new maps application.
Here are my questions:
1) Is there a good way to find out if there is a specific program that is not allowing sleep (w/o uninstalling everything and adding them back one by one)?
2) How do I fix this problem? Would a hard reset work?
3) Generaloes anyone have any ideas on how to fix this? Why wont my phone go to sleep?
4) Could this have anything to do with the new maps/navigation update that Google sent out OTA last week?
Right now it has not slept for over 5 hours, but I been pressing the power button (not turning it off) when I put it down.
I ca provide a list of programs if that helps, probably some statistics too
Thanks!
In Spare Parts under Battery usage, there is a "Partial wake usage" option. Did you check that to see what is keeping it awake?
Since Last Unplugged:
Android System: 6m 16s (blue bar)
Dialer: 1m 40s (blue bar)
Facebook: 56s
Google: 44s
Media 28s
Google Voice: 20s
Calendar: 20s
Messaging 4s
None of that seems to make sense when you look at:
Other Usage: Time Spent Without Sleeping: 6h 36m 1s..
Maybe I am mis-reading it?
Thanks!
Hello Guys,
is there any way I can disable this annoying Feature that turns my top and nav Bars red then my Battery reaches 40 % or lower? And no I don´t have Battery Saver enabled or some other Settings.
The Reason is: When this Power Saving mode is active, Whatsapp don´t get messages when the Display is off, GPS is not working not even in Google Maps (says no GPS Signal when Display is off)
Hope you can help me Guys cause otherwise this is a function that is total useless in my Opinion when you can´t disable it.
Edit:
Ok found the "Bug".... Go to Google Talk / Assistant and say "Open Battery Saver" and select 5 %, cause never was selected at my device and it didn´t work. And yes I changed the Language to englisch cause I don´t know how the Command is in German.
