How to avoid battery drain in WM6?

I've been playing around with all the WM6 rom for my trinity and found that just about all of them have a "battery drain" problem....
Anyone, anywhere has a soltion to this?
Thanks

Well try to keep your bluetooth active only when needed. same applies to wifi and gps.
Other than that some people have suggested that original radio is less power consuming so if you have upgraded it maybe you can consider going back to standard!!
For me the phone with periodical use of bluetooth, wifi, gps and about half an hour of talking time in calls, can last easily on two days!!!

The same
I have the same problem. For "steladamo": Of course I have a GPS, BT and WiFi turned off.
In such a circumstance my batery drains after one day whereas WM5 kept my battery alive for several days.
Any solution?
Is there any tool how to log system actions? I'd like to see what my WM do.
Thx!

Just upgraded to wm6, found out that the incoming beam (infrared) is turned on by default...and that is a power-user...no probs after I switched it off...

Have the same issue.
Infrared was turned on also in my case. Turned it off, let's see how long my device will last now.
Thnx anywayz.

How can you tell infrared is on or not?
By 3rd party tool?

do you try last radio 1.46.00.11 or 1.46.30.11 ?

Yea, how do you do that?

Settings --> Connections --> Beam

Or with the cab which allows to have 10 buttons in commanager

just flash 1.46 radio ...

same problems with both radio 1.41 and 1.46
wm6 and the battery lasts one day, without beam, wifi, or bluetooth on

Turned off infrared. Switched synchronize every X minutes to manual outside office hours. Made a lot of difference for me.

UMTS band ???
Go to settings and choose phone icon then go to the band tab don't use auto but just put it to gsm....utms eats power....

Where is the 10-button com cab?
Does that work with the ax3l rom?

I can confirm that the AX3L_WM6_WWE_v2.0.8.1 rom has had the battrey leaking problem resolved!
So if your not using this rom, flash it now!

I confirm that with heavy use I can still "drain" the battery every day.

Anyone has the CAB file for the Communication Manager with the IR Beam on/off button in an HTC Touch style ?
I can see that NBD has it in his Wizard ROM

Hi,
Did a quick assessment in http://forum.xda-developers.com/showthread.php?t=319278
Here it is for your convenience:
Here is a guide from my recent observation.
It is based on WM5 using BatterieStatus.cap, would be great if someone can do similar to WM6 in comparison.
I also used :
HTCustom1.7 to turn off HSDPA
Turned off Bluetooth and Infrared Beam
(I did discount short burst when app switching)
Idle, screen off = around 21mA
Idle, screen on, low brightness (3 notch from left) = around 62mA
As above, connected to 3G, No applications running using 3G = around 64mA
Active browsing, basic sites, 3G, around 300mA - 400mA
Active browsing, graphic intensive sites, 3G, around 400mA - 600mA
Active browsing, HSDPA on, basic site 500mA - 600mA
Passive browsing, IE open, no action, 3G, drops to 68mA
TomTom using inbuilt GPS, waiting for GPS lock, 180mA
Idle, screen on, low brightness, but 'Receive all incoming beams' (IRDA receive on) also 62mA!!!
Audio call, 3G, 350mA
Mediaplayer, streaming video from Internet, around 600mA.
I believe 600mA is around the ceiling.
Some calculations: Standard Batterie is 1600mAH.
So total idle/standby time is about 1600mAH/20mA = 80hours or 3.3 days
Total call time is 1600mAH/350mA = 4.3 hours approx
Total surf time is 1600mAH/400mA = 4 hours.
This lines up with my usage patterns, idle, screen off most of the day, usage about 30 mins browsing every day, batterie last about 2.5 days.
(Hobby engineer hehe)

Nice man!
And this does also fit into my calling pattern. I have to load my battery every evening, but I also call for about 2 hours per day. Use wireless mail/calander/contactsynchronization with outlook and Windows Live mail. And regular use of some other features.
So like i said in other posts, the drain issue has probably also to do with the expectation people have from the standbytime of their device on heavy usage.

3 questions. gps speed / battery / tomtom splashscreen

heya. i've got 3 questions, hope some1 could help.
i recently upgraded my p3300 to WM6 (official HTC rom) and as i was at it, started to wonder about a few things.
1) in tomtom, when configuring the GPS, i can change the baudspeed (actually at 4800). if i increase that, would a) the GPS navigation while driving be smoother, b) i get a faster satelite fix and most important: c) would the battery last less or same?
2) about the battery... i use very few apps and most of the times i make sure they are 100% closed. i use the calendar, notes and few phonecalls per day. sometimes i turn on tomtom for a few minutes to find a street when walking... but i think the battery life is very short (an average of 1% per hour in standby, more battery loss when using the pda, making calls, etc)
is there any tweaks, programs or whatsoever to see what exactly is consuming XYZ of my battery? and improve it's life?
3) after upgrading to WM6, whenever i start tomtom, i get that logo-splash screen (didnt get that before) is there a way to remove it?
i have many more doubts, but i think i'll leave em for when i solved this things. thx for answer.

1) I didn't noticed differences neither in fix time nor in navigation smoothness.
2) I doubt that it is possible to measure power used by certain application directly. I had problem with power drain and resolved it by switching applications off and on (S2U was guilty), but it seems to me that my Artemis use more power after upgrade to WM6 to.

any1 got any more comments? which is the best way to track your battery life and improve it? any program around to help on this task?

If you want to compare your device power consumption to my Artemis I'll give you some measurements (not very accurate actually):
When I tested my device while playing 320x240 divx movie with TCPMP, fullscreen, brightness set to max, no audio - battery operated about 5,5 - 6 hours before PDA powered off automatically.
During 8 hours in stand-by (I didn't used PDA at all) it was about 5-8% battery drained, but when I switched Pocket Plus indicators (memory, battery, SD free space) off - after 8 hours of stand-by there was 100% battery (full).
Hope this will help you. If you do your own measures let us know.
Good Sunday

ok, as far as i have seen, there is no application that tells your how much battery each application you run, uses. i guess thats normal.
but, is there something like the windows taskmanager, telling you how much CPU and MEMORY each application that runs in the background uses? i think if there is one, that would give a good start on my investigations.

i'll try it, however i've read somewhere that this program itself is a battery-drainer already?

With BS I had 100% battery after 8 hours standby and I didn't noticed more power consumption while normal use (some phone calls, PIM, games, Internet), but you must try to know how it works on your device. Try it and then write about your findings.

Hi,
baudrate has noting to do with refreshing inverval of GPS. The refresh wrt the satellites is determined in the chipset, and the baudrate is the speed in which the chipset (which is actually an external device) communicates with the serial port of the device. Normally speaking the baudrate for gps is 4800 (it is NMEA norm), but also other rates exist for example for bluetooth devices the baudrate is only the speed with which the serial transfer of data is done. It is in the end the GPS software you use that will determine how fast your position is updated on your screen. It can happen that if you set the baudrate wrong, that the data is not received properly, because the software expects the data to be presented at the baudrate you set, and the device delivers at a different rate (like speeking too fast to somebody). It is therefore important to set it correctly.

You could try TaskManager 2.7 from FdcSoft. It shows CPU load en memory load.
Just add the .exe to the sd card and run the file. Use the tabs to selct Process / CPU or any of the other tabs.

thanks for the explanation.
going back to batterystatus, i am tetsing it now. specially the overclock tool to actually UNDERclock my phone, hoping the battery lasts longer.
however, as for what i've seen, when the phone goes into suspend, batterystatus sets back to the 201mhz until it is unsuspended. so that's actually useless.
but it tells me enough info to get an idea about my power consumption, etc.

Not exactly useless - if you read e-book or WWW pages your PDA can save power with BS (although I don't know exactly how much).
About underclocking in standby there is explanation from BS Howto:
Could you make the cpu clock down while it is in standby?
There is no need to. Most of the devices are doing this by themself. As soon as you push the power-button (explicitly not a program mapped to a custom button for this job), your device will gradually stop execution of code and clocks the cpu down.
The latter implies that as soon as you push the power-button, BatteryStatus and any overclocking by BatteryStatus stops working.
Some tests showed that your device automatically steps down to 52MHz and maybe there is a state while the cpu is completely stopped (0 MHz) too.
I'm curious what is CPU speed of Artemis in standby. Maybe somebody knows that and will share with us?

Keep ON wireless in standby mode

Do you know if it's possible avoid turn-off wireless in stand-by???
I'd like to use VoIP with my Artemis (with hand-free and wireless connection), but it's impossible becouse after 1 minute (my pda is set to turn-off after 1 minute) the phone goes in stand-by mode and plugs off the wireless antenna.
Can I set "Always on" to wireless connection???

as yet i failed to accomplish this. all i can do so far is turn off the monitor to save a bit power. not the same as standby mode at all though.

I've got this tweak from somewhere, I'm not sure (maybe wiki page):
"AUTO DISCONNECT WHEN GPRS IDLE
you can edit the registry key ...
HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/CacheTime
Change from 600 to 60
it will disconnect after connection is idle for 60 seconds ...
There's also another key needed to be set. Otherwise, my PDA still has always on 3G data connection.
HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/SuspendResume
Change from ~GPRS! - Always on
to GPRS_bye_if_device_off - switch off after timeout"
It may help if you make the changes THE OTHER WAY ROUND. For you the desired value in 'HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/SuspendResume' is '~GPRS!' And the cache time value should be set to '0' (as infinite), if it doesn't work, set to a high value (i.e. 3600 - it means 1 hour).
I'm not sure it helps but it's worth to give it a try...

i guess he was talking about WLAN connection, not gprs or 3G. however, i might be wrong.

You are right, sorry. I've just misunderstood the problem, paying not enough attention to the first post...

So the only way is disable auto sandby and swith-off screen?
I thought a way to solve this situation could be keeping active OS during VoIP connection, just to avoid standby...

Its not enabled for a very good reason, it consumes so much power your device would last just a few hours before running out of power.

that is true. however, they could still give us the option
i think the real "problem" is that WLAN needs the OS running to work. the GSM unit is working differently.

Using S2U is a solution for me
Using S2U2 is the only solution for me.

It seems to be what I want, an application that avoid standby mode but preserve battery (setting lcd off, various device option off...)
I'll try it!

Skype
I am not sure if this is still relevant, but in skype i think to have seen an option that says: "disable stand by mode when connected to Wlan" or something like that...
however of course the "batteryproblem" will still be there...
Please post your experiences with S2U2 once made, thanks!

Don't mean to "thread jack" but how can I tell the difference between the screen just being off and the phone being in standby mode?
I'm asking because I'm having a problem with my phone when I turn on Flight mode. Usually I turn on flight mode at night or in a meeting but I'm finding that the battery is still draining (rather quickly too) when I'm in flight mode and the device is off all night. If I'm at 40% batt level at 11:00pm and put the phone in Flight mode, by the morning about 6:30am, the battery is down to like 5%! And there are no programs running at all, screen is off, device is untouched all night. So when I saw this thread, I started to wonder if the phone was in really in standby or if the screen was just off.

Is S2U2 the option to keep the WLAN enabled when in standby mode?
I know i can disable going in to standby but would be nice if it can be done without this.
The power drain is most peoples concern but if i'm at work i have it plugged into the power anyway but would like to use one of the WLAN's here that isn't being monitored

[Q] Force WiFi to stay active when screen is off?

Hi everyone!
I'm using OpenDesire 4.0.4, and while it's more or less the perfect ROM for me, I'm getting a little annoyed at the WiFi. As the ROM is based on CyanogenMod, it has the same WiFi behaviour: When the screen turns off, the WiFi enters power saving mode, regardless of the apps that are active at the time, or the amount of traffic over WiFi at the time.
The problem here is that any application that's using WiFi pretty much just stops as soon as you turn the screen off.
1. Sipdroid during a call: Massive packet loss as soon as the screen turns off. You may hear a garble or two, but nothing intelligible.
2. SwiFTP and other FTP servers: Connecting to the FTP server and navigating to folders takes ages when the phone is in standby. Transferring files is more or less impossible (times out)... Everything's fine when the screen's on. If you transfer a big file and turn off the screen during the transfer, you basically pause the transer - turn the screen back on and the transfer goes back to full speed
3. Market: If you turn off the screen while a lot of apps are going to download, like after pressing "Update all" for a few apps, more often than not they'll just fail in the background.
Now, I could beg and ask the ROM developers (Kali for CyanogenMod on Desire, or AdamG for OpenDesire) to just change this behaviour, but it seems that most people are happy with the situation, as it causes the WiFi to use very little battery on standby... so I'm asking if anyone knows how I could change this myself. Is it even possible to do this at runtime without baking it into the ROM directly?
Or am I SOL until (or rather unless) AdamG or Kali takes pity on me?
I'd love to hear some input - hell, maybe I'm just doing it wrong ... Thanks in advance!
PS: Yes, my WiFi Sleep Policy is set to Never, and the Desire DOES stay connected when the screen is off. Just in a very low power mode...
-edit- Should have searched, sorry: http://forum.xda-developers.com/showthread.php?t=752856
-edit2- Looks like there really isn't a fix for this... Anyone found a way to completely disable PSP on the Desire/Nexus WiFi?

I'm on the same ROM as yourself. What value is your "screen-off lock screen delay" set to?
In my observations, the transfer in the state you mention still persists albeit at a very slow rate and the WiFi chip is certainly placed in the LOW power state, although on.
I'm unaware of any workaround but what I use myself when transferring bulk 1-7GB files through WiFi from my PC/Laptop, which is to change the value of the screen lock delay at screen off under Settings>OpenDesire>User Interface>(last option) to a high figure, like 10-30m, depending on how long I'm expecting the transfer to take. It's a trade-off but you'll still save over 95% of the power since your screen is off but the WiFi/SD/CPU remain working as when the screen is on. Maybe you've tried this already?

That's not a bad idea... brb testing .
-edit- Didn't work
As soon as the screen times out, my transfer speed drops to nearly 0 - even with the lock delay set to 30m... :'(

OK, that's confusing. I'll be back by tonight or morning... I have much testing to do on this since for sub-20mins, my connection runs plus 200Kbps according to the PowerTutor log in such a state. Usually it would drop to 0.3-8Kbps when the screen switched off.

Mine drops to practically 0. So low that due to overhead, FTP transfers pretty much stop completely...

I've seen that the linked kernel module provides a temporary workaround for you guys now. During the course of my testing your concern I basically found my WiFi module isn't ever turning off nor switching any connections off - it's always awake and can always transfer some data. Even in the LOW state it is connected at 24Mbps. Whatever I did I couldn't change this behavior on 4.0.4. Time for another wipe...
OD has many user preferred options baked in working fine alongside the conventional options so it'd probably be best suited for a toggle of this feature to be implemented for you guys (if at all possible). Not sure if that WiFi module power state behaviour is write-able and changeable on-the-fly before a reboot, should be, as it's only changing a hardware state.
-----------------------------------
- Sent via my HTC Desire -

The new Wifi module is working perfectly here. No more performance problems, and my power consumption has actually gone DOWN. Probably because I have a bunch of connected apps running in the background and PSP is very inefficient for that.
Also, the delays in Chrome To Phone and Appbrain web installs are gone...
I'm loving this fix...

[Battery] Excellent Solution for high battery drain

Hi to all
After many fights with my loved Desire i'd found an excellent solution for the high battery drain.
I have the OxygeN ROM 2.3.2 (very very very nice and stable ROM) but the average life of a charge was 1 day.
Searching on the market i'd found the app "Green Power" (free version). This app allows to manage the WiFi and/or 3G connections when the smartphone is in stand-by (SLCD turned off). Setting the parameters it is possible to swith-off (i.e. every 30 minutes) the WiFi and/or the 3G. This make a big decrease of energy consuption. So my average life of the battery between two charges is 2-2.5 days .
Very very very excellet solution
Hope to help anyone
BR

If you just want to do wifi its already build into the roms. You just need to go too wifi settings and hit the menu button and select advanced settings then play with "Wifi Sleep Policy" I have mine set to "Never when plugged in"

I read before that the WiFi radio actually uses less power than the mobile data connection, so leaving WiFi on and Data Off would drain less battery. Although obviously both off will increase it, which is how JuiceDefender works as well. But i find if you can live with all data off for periods of time you probably don;t need a smartphone in the first place, the whole point of them it to be always online for push notifications and the like.
