Battery drain tweak? May solve drain :)!

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

Battery lifetime

Is a lower lifetime characteristic of a WM6 ROM? Before flashing I used to be able to get ~two days life on WM2003, now I struggle to get 12 hours.
I do have the Soft GPRS tweak installed.
I've seen other posts relating to power off at around 30%, but this isn't a problem for me - I'm still getting life at 12%. It's just that I get to this low level so quickly, and have to charge each evening to have power in the morning. My battery is original, and otherwise the ROM (helmi_c's) is stable.
Any hints or comments?

mine is significantly shorter than when i was in WM5. but not as bad as yours. try this. go back to WM5 and see if it still gives u 2days.. then go back to wm6. then if u still get 12hours max with the same usage as you have with wm5.. then it's the ROM.
if you get poor batt life even going back to wm5, then maybe it's the battery. consider borrowing a battery, or buying a new one..

Are you sure your battery can stand only 12 hours ? it's too short. Try to reduce thre brightnes to save the power of your battery.

Ta for the suggestions.
I already have my screen brightness adjusted, and auto power off as appropriate.
Battery is the original, but behaved with 2003. I have two Himalyas (bought the second off a colleague for £40 as nervous about playing with ROMs!) and so two original batteries; both behave the same. I also inherited an aftermarket battery which is truly awful - goes haywire after down to ~45%.
I did try WM5 for a while, and don't recall the battery problem. As I have two devices, switching one to WM5 and comparing is a good suggestion. Unfortunately I need one application (NotifyLink - see thread in the WM5 forum) that I've not been able to get working in WM5, and *does* work on WM6, so if I need to go back it's WM2003SE for me :-(

Before trying to flash back to an older rom, consider some other battery saving options.
Lowering your screen brightness was a good idea, which you have already done.
Some other things to consider:
Turn off "Receive All Incoming Beams" until you actual need to receive something via bluetooth/IR.
Turn off bluetooth if you are not using it (this used to be a massive drain on my himalaya)
After closing a program, go to the task manager and make sure it is actually closed. THe cross in the top right hand corner usually just shrinks things. You can buy/download applications I believe that will actually properly close a program. I've on occasion had 8 progrms running at the same time simutaneously before closing them.
Make sure the terminals on your battery and himalaya are clean (where the battery connects) and also test to make sure your battery is seated correctly.
Change the timeout for your device (IE how long it will wait before turning its backlight off, and then turning off in full). Mine is set to 1 minute. You can set it as low as 30 seconds but I didn't like this as I felt it would wear out the backlight.
If I think of more I'll come back and write them. Perhaps someone has already made a "Save battery power" post. If not, perhaps someone will make one and the mods can sticky it.
cheers

The battery is geting life expired. Better buy a new battery..

Thanks for all the replies and suggestions.
If I've besmirched either of the ROMs published on this forum then please except my apologies - I discovered that my battery problems are NOT due to the ROM. But nor are they due to my battery!
Re-Flashing (or hard reset with reboot options) gives me good/normal battery usage. I therefore figured that my problems _must_ be due to an installed application. It didn't take me long to determine that this was due to NotifyLink, which I unfortunately need to install in order to receive my corporate email. With this present I lose approx. 6% battery power every hour(!), even with GPRS disconnected and the application not checking with its server. Just installing (even before configuring) the application I get this immense battery drain. Weird. Removing my SIM card doesn't help. Neither does uninstalling; I need to hard reset before battery consumption returns to being acceptable.
As I need this application it looks like I need to accept the need to top-up every evening.
(Medium term I know my company are moving away from this app, but will require DirectPush - anyone know if we can activate this in a Himalaya ROM?)

i recently replaced my battery for a new one. it was near 3 yrs old and it's battery life was steadily decreasing lately, shutting off just about 6 hours after a full charge! when i bought a new one it shuts of at 5% on the same rom and operating conditions, nice huh!?. so as a rule of hand slash of around 15-25% of battery life for every year of use. better yet save up for a new one while your on it .

Good job. As you can see on notifylink's newsletter they're very specific on devices fit for the job, for example not just any Wing, but TMobile Wing...

As far as I know all you need for direct push is correct settings of exchange server and a device with WM5 or WM6 with built in MSFP or WM2003 with Global Contact Access installed. MSFP should probably be in your WM6 ROM unless your cook cut it out. In that case you can either try to find it in the ROM kitches of recent HTC devices and see what happens if you cook it into Hima ROM yourself. I don't know which file(s) you should use. Or you can download GCA and see if it works on your WM6 Hima.

Maggy - Many thanks for the response. Yes NotifyLink do recommend specific devices, but I've no idea if their battery consumption is any better. I do see from various postings here in my company that I'm not alone with problems - generally advice is to just check with the server less frequently, etc, which doesn't solve my issue. I'm going to have to live with this inefficiency for the moment.
As regards DP, I'll await with interest my company's progress in moving to this technology. Thanks for your information!

I have similar problem since WM6 Tofclock ROM is installed - getting just about 24hours battery life....Although the battery is quite old the Rom has definetly some incidence on this --- I have installed batti 2.1 following some threads i found here, hope it will help

Actually, I found out the same strange thing, while I was trying to solve another problem. I changed almost all of the OS/Radio Roms combinations, and with WM2003 the battery time when the phone is in stand-by is significally greater than with the WM2005 or 2006 Rom (days vs hours)... and this happens with every radio rom.

Any solution to battery drain?!

Hey everyone. I recently purchased a 8925, and am experiencing the battery drain issue that some others have mentioned. I used to own a 8125 and its battery life was much longer (easily 3 days of my usage). I installed batterystatus on the tilt and it seems at idle with all apps closed its pulling 60-60 mA, where my 8125 used 10-15mA. Has anyone come up with a solution for this? I currently have 3.29 hardspl with the stock wm6.1 installed.. any help is much appreciated

turn the lcd brightness down, get kaiser tweak...set your mobile internet connection to go off after a period of a minute or two of non usage (thats a big one)

I have done these above listed, brightness down all the way, i disabled the internet connections with nodata, and i did a couple things with kaisertweak (sd power management). This seems to have no effect on the drain

Less is better when it comes to longer battery life....

Maybe all the extra bits of software and utilities that have been installed are gobbling up those CPU cycles (and consequently the battery charge). I have a very basic setup on my TyTN II and reducing the screen brightness right down as well as changing to GSM (rather than 3 G) makes a huge difference in battery life. Even disabling HSDPA and resorting to just 3G makes a difference. It's time to simplify things I think and rather than installing apps to stop a data connection starting up for example, delete any data connection settings on the phone and simply don't do anything that may require a data connection.
How long are you getting out of a charge, doing what sorts of things how often? I'm sure if you hard reset back to the basic ROM and test again with just these few changes, you'll notice a big difference

If I simply flash the stock ATT rom on the phone, and install batterystatus to view my drainage, it is still at 47mA. It seems turning off all the data stuff saves maybe 10mA... i understand that a bad battery would drain faster but would that make the 47mA on standby? i thought that measured how much the phone was using? maybe the battery is bad. just yesterday i left at 7:30am with a full charge. I litterally sent maybe 4 text messeges and maybe a 3 minute phone call, the rest of the day it was on standby, and at 7:30pm it was down to about 34%! this is unacceptable!

Does anyone know what batterystatus reads? either the rate that the battery is losing power or the rate the phone is using it. is it possible that the battery is bad and would cause it to drain at a higher amperage? i know a bad battery drains faster but dont know about this.

I feel your problem. My tilt is so bad that it still drains while charged in the car. Maybe a bad battery but this is crazy.

ok I talked on the phone today more than usual (maybe an hour max!) and it shows that the battery drains super fast when making a call, which to me says the battery is just toast because a call uses more power. I was hoping to find a solution but i think I will just purchase a new battery.

how about buying a slim extended battery on ebay, the 1600mah one. You will definitely notice a difference

Well from what I hear the ATT ROMs have lots more 'stuff' than the native HTC ROMs but whether that means more CPU cycles are used when those programs aren't started I doubt. It's really background utilities that'll be of concern. Rather than installing software (which itself will use battery charge) to see why your battery charge is going down so quickly, what's wrong with going about your normal usage without non-essential utilities and keeping an old fashioned log of how long a full charge lasts and what activities for how long you used your device for? If you try some of the suggestions already given and keep a careful log, you will notice a marked improvement - I did. Whether you wan't to keep those changes though is important. I found the screen was just to difficult to see at low brightness settings when out in the sunshine so I've set it back to a high level and carry 2 spare batteries with me when I'll likely be out and about using the device for a full day - I've yet to get through all three batteries in a day and they're compact enough to easily carry around. With my cradle that has a battery recharge bay, I can also recharge all my batteries overnight.

Battery performance of official ROM is the best!

I have tried a lot of roms,including touch it v4.5,Jack's 3.0,offocial rom R2AA010 and some chinese roms etc .
The battery performance of R2AA010 is the best,much much better the others.
I don't know why,someone says the official rom lower the CPU frequency,but it still runs quite smoothly and fast.
I hope someone would find out the real reason and this power issue can be resolved in new roms.

The batt life for the cooked roms seems abt the same to me...

well, doing my personal testing, I just tested official (R1 and R2) and Jack's 4.0, 4.5 and now 5.0 (waiting till fix'd version to do a batt test) and I just find all version with the same autonomy.
the main thing I see, Is that I don't configure HSDPA connection autodisconnect in advanced settings (so the connnection is keep alive) battery drains much faster (in all roms).

why my battery drained so fast besides the official rom,maybe somewhere default settings are different between the various Roms.

tf3d just needs more cpu power and memory than the usual today screen of the stock roms. this, of course, drains the battery faster.

Battery consume depends only on cpu and memory (flash too) use (and on the radio, but you can't change that), so it is independent from the roms. Of course heavy loaded roms and today plugins use more power, so you decide what is important for you.

Yes
I agreed. But my big disapointment is the official have a lot of anoying application that I think I can't live with it.
The official ROM cooking might be the good chance.

it's quite surprising me that x1 battery (1500 mAh) performance is not better than TP (1340mAh).

TP has only VGA screen while the X1 has WVGA and the higher resolution screen consumes more power. So it's not so surprising

imo, battery life for wm6.5 by itje is the best
official rom lasted me around 2 days or less back then

my battery was only lasting about a day until i changed to Touch-IT by itje and the battery is now 3-4 days depending on use.

my battery life is completely pony
This is something that is a big pain for me - my battery doesn't even last a day using itje's roms (haven't tested others yet)
I think HSDPA/3G has a lot to do with battery drain. The stock rom seems to disconnect it when it's not in use, but checking my phone now, it's been connected 11hours (since I last reset it). I could be wrong with this comment tho as I've not run the stock rom in months.
Have had a poke round the registry and can't find anything that might be a timeout...anyone more knowledgeable about this than me care to chime in?

you can setup a timeout with the "advanced config" application and yes, leaving data connection enabled draws more battery than just letting it connect when needed.

Battery Life hacks? Which one?

Hi,
I came across this cab file today for the Kaiser http://forum.xda-developers.com/showpost.php?p=2132767&postcount=151
its right said:
ok guys, some of you want to increase the battery life, i attached a cab file which contains these registries:
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
"DisablePowerManagement"=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
"DisablePowerManagement"=dword:0
all of these can improve the battery life, but if you face any issues with WiFi, just check these registries .

anyone have any comments? surely im not the only one trying to get a full day out of the stock battery.

This is the best hack out there.
http://cgi.ebay.com/AT-T-TILT-8925-...s?hash=item1c05a465c2&_trksid=p3286.m20.l1116

if I not wrong, sp call battery hack ..it not really hack to battery, It only reduce the phone keep searching the network (which consume a lot battery ...according to some forum).
I think this one better ..2800mah ...
http://www.lelong.com.my/Auc/List/2...00-110-120-O2-XDA-Stellar-2800mAh-Battery.htm

My phone will last about 3 days by measurement if I'm not running Flexmail with two mailboxes online. Otherwise, 14 hours.
Want a full day out of your Tilt? Limit network activities, or interactive activities, and don't use the GPS. Network, backlight, and GPS are probably the biggest power users on the Tilt. I assume WiFi too, but the only thing I've used WiFi on my Tilt is for scanning for open access points.

Sorry bumping thread couple of months old....
I've got a Kaiser HTC TyTN II and my battery is a shame.... i can't get it until the end of the day, always getting empty at the end of the day....
What can i do to improve the battery life time?
I've installed those cabs, but nothing really happens....
My phone idle during the night takes like 20-25% of the total battery.
I just use my phone to make and receive calls (lot of them), and sometimes the bluetooth when staying at the car.
Some time ago i ordered a 2800mah battery, but i really don't want to carry always a replacement battery with me, besides its really heavy and big....
Thank you for you advices.

There's an old saying begars can't be choosers... Kinda makes sense you want better battery life yet you want to stick to stock battery.
Ummmm? Buy a OEM new stock battery if the size of 2800 is too much? To be honest the Tilt is a brick anyway so i'm happy to have aprx 1cm added to the base... Also maybe time to try all the Radio's available to see if you can get better battery life, while @ it hard-reset device to start from fresh
