What turns the GPS on/off?

Just got my O2 Orbit yesterday. An awesome piece of kit. It's impossible to see just how small it is in photos somehow. Really nice and so far it's performed great. I happen to find all of the things others have complained about to be plusses (the roller and wheel, the location of the MicroSD card), so it's ideal for me, really ideal. Glad I waited for the Orbit rather than the P3300 too, even though I'd rather give my money direct to HTC! It's much nicer looking.
Anyhow, my question is that I expected GPS on/off to be on the Comm Manager screen but it isn't. Am I right in guessing that what turns the GPS on and off is whether something has COM4 open and listening? So as soon as an app closes COM4, it starts to lose location? It might be nice if there were some programmable delay post-close where it keeps monitoring in case something else opens COM4 again a few minutes later.

I think this is because keeping a fresh GPS signal is severe on the battery life.
I have a BT gps receiver which works around 20 hours on a default nokia battery. But ofcourse the Artemis is a whole pocket/phone which draws its power from a 1200mah battery.
All GPS receivers need to get a fix at the start, this takes from 30 sec. up to 2 min.
It could be when disconnecting it saves the GPS positions so on another connection it can find the satelites faster. But I don't really know how the technical part works and if this is true.

I don't know how exactly it happens programmatically, but what I know for sure is that it is turned on/off by TomTom. As long as TomTom is working, the receiver is working, too.

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.

How to enable the gps module permant?

I want to enable the gps module of my mda compact iii permant. The problem is, that tomtom enables the module at startup, but if I exit the application, tomto disables the module. It tooks to much time for the gps sync.
Any suggestions?
Regards,
Rushmore

sorry, no chance. If there is no software, wich is using the GPS, the GPS urns off.
That's okay, because with GPS on, your device will run 4-5 hours, only.

you can use fransons gpsgate

what i usually do is just press the red 'End call' button, this 'minimises' TomTom, so it is still running in the background, thus still connected to GPS

after walking with memory map on, after 2 hours the battery went down only 8% and thats with the cpu overclocked, I reckon it would last a good day with gps always on...
could use visual GPSce its a small free program that just uses the gps to get a siginal and gives details about your position, its not cpu demanding at all and will run in the background with hardly any drain on the battery

GPS on the TP2

I am losing my mind with my GPS. I have had my TP2 since last August and I have never been able to find a solution to the horrible GPS quality. I have tried matching up the ports, changing the ports, different software, hard-resets, I have installed the hotfix, I have called HTC, but things are still terrible. The only thing that ever cause an improvement was manually choosing the ports and such, however the improvement was only slight.
I have used GPS on Google Maps on the iPhone under the same provider (Optus in Australia) and the moment I opened the program there was always a GPS lock, not once did I ever have to wait or get it ready, but on my TP2 using Google Maps (or any other application), sometimes I am forced to wait minutes before getting a signal, if at all. I have searched and searched for a resolution but im not finding any. I just don't understand what I paid top dollar for, I chose the TP2 over the Xperia for it's GPS capabilities, but its hardly capable. I feel as if I am out of options, i've had it for too long to get my money back; I would really appreciate your thoughts on this?

I use iGuidance2009 and have no problems, though I do update quickGPS regularly. Google Maps I dont know about as I dont use it.

This has been a problem ever since the Touch Pro. My old Kaiser never had these horrible GPS issues, Touch Pro and Touch Pro 2 do.
What I have found to work well is to toggle the phone in the Comm manager when GPS is not working correctly.
Also, if you can get AGPS to work correctly, that does wonders for GPS lock time speeds! It would take minutes before, but once AGPS is set to work correctly, I can get a lock in 10 seconds! You have to go into the registry and make sure AGPS is set to use the right data connection.
This only improves acquisition times, it does not reduce the lag which was introduced in the original Touch Pro.

Google maps is probably the worst test app for speed. I use TomTom and iGo on Juicy R5 now, default rom before, and both have no lag. Google maps lags as much as 30 seconds, Garmin and also a few free gps apps I tried lagged 10-15 secs. So this is really, really app dependent. Don't know why.
As for lock speed, agps is a must. If QuickGPS/SEASGEE isn't working then you get the same lock speeds that you would get on old, old car gps systems (up to 5 mins to get a lock).

It's just you with such serious problems, maybe your phone has problems..

AGPS is key to getting a fast lock. That's where you should be focused.

Some registry tweaks may improve your fix. It rocks for me and others owners, but not sure for every body.

No, its not. Everyone has position lag. It isn't unbearable, but it is pretty annoying. You take an exit on a highway and it takes about 3 seconds to realize you took it sometimes. What is really weird is it keeps going on one road while the arrow turns in the direction you are headed until it finally places you on the correct road. That part may be due to TomTom though, but I'm not sure.

As per my personal experience, this is due to internal GPS data filtering by WM, so tweaks recalled by woaloo (I mean reducing of WM's GPS-related data buffer sizes) can help here.
Be careful however with it as too low values will drives GPS to become "nervous" - your position will become unstable, starting to jump randomly with a radius of few hundreds meters.
Another reason of the lag is (most likely) related to the navi software one uses. I use iGO8 and there are for sure settings moderating position behavior from pretty quick (but unstable) to rather slow but noticeable more stable. I personally prefer this last one.

To the original poster, have you tried running a program like VisualGPS? If so, how much signal strength is it showing for the satellites? I see as high as 39 when indoors. I get quick and accurate locks and I am very happy with the GPS performance. I have to believe that you have a hardware problem.
As for the thread drift on the few seconds delay, yes, that is there, but not a big issue.

Personal experience with the GPS... initially could never get it to connect, basically because every time i tried i was inside behind venitian blinds..... never use GPS before so my bad.
Walked outside and it was great. About 10 secs or less to lock, the lag is only a couple of seconds, no more than 5 secs. Added the tweeks and it was improved slightly. The accuracy was within 5 meters or less (used the property boundries in google maps to verify).
Moving at high speed it was pretty good too.
Compared to other phones and iPhone borrowed from a mate there is negligable difference in the accuracy and lag.
BRETT

So the GPS performance on the Touch Pro 2 is not that much better than the Touch Pro? The receiver on the Touch Pro is extremely weak.
At my work we have a GPS re-radiator for use with the equipment that we build. Indoors using the re-radiator I can get a lock in seconds with 11 satellites (the signal is abnormally strong). Outdoors, I'm happy if I can get a lock with 7.

I did try something like that, not sure if it was VisualGPS but it showed me the strength of GPS signal and it was quite accurate with how the GPS appeared to be behaving.
I got the phone's motherboard replaced and that fixed the issue. Thank you all for the replies though, it was possibly faulty.

Have the new Energy rom on but used the GPS hotfix. Seems to have increased lock time considerably.
I'll keep an eye on it though in case the lock time increases...
Wonder if we can find an app that would imbed GPS co-ordinates in any pics we take... Got a Samsung S8300t as well & it does this though the GPS navigation software is non-existant....

One of the extra camera modes you can unlock in the TP2 is a geotagging mode that does exactly that. There's a number of ways to enable them...Rhodium Settings Tool has a switch for each of them individually (burst, sport, video share, and geotagging), or you can just run the cab below

....and, for anybody else on this thread who hasn't tried it already, I'd suggest checking out the cab fone_fanatic put together to help with GPS locks on the TP2, details HERE

Battery Life

I have a widget that shows me how much I have left and when I unplug it after a full charge, I have 6 hours left.
Ridiculous.
This is on auto brightness, wifi, twitter/facebook/mail updating every 15 minutes.
whenever I take my phone out the house I have to bring a charger...
bloody ridiculous.

couple of points.
1) When you leave the house, don't leave your wi-fi on! I find wi-fi to be the biggest battery drain out of everything ( expect gps)
2) I use a brightness widget, therefore when your in doors you can have it on low, then when your out doors have it on high, i assume this will use less battery then auto brightness
3) why do you need facebook updating every 15 minutes?? Do you honestly look at your phone that much when your out? change the settings so it updates every 15 when your on wi-fi at home, and every hour for when your not.

Wifi isn't an issue. I leave it on 24/7 as well as bluetooth and still can get 36 hours out od a charge. Its hooked up to wifi 20hrs a day as well.

1. Battery and other constantly updating widgets are one of the causes for battery drain. Get rid of it.
2. Battery widgets try to get an estimate of your typical use. They are mostly wrong in my opinion
3. I can get 6 hours of battery, yes, but only if glue the phone to my hand and use it constantly for that time
4. there are tons of battery threads around, use those suggestions (mid brightness, no live wallpaper, turn airplane on when you know coverage will be unavailable for long, etc)
5. Battery gets better in 10 days.
6. Most people can get at the very least one day of heavy usage. If you really need to hammer the battery get a spare one, they are cheap. Oh, and realize you are lucky because you CAN have a spare battery !
7. If you are using an automatic task killer, get rid of it.

1) go to the market and search brightness level, or brightness widget, there are a number of these. The best i find is brightness level by curvefish, it lets you pick a percentage and keep at that .
2) Cant remeber actually where the settings are but there is a way. But i prefer to use another widget, autosync on/off, this allows you to update every 15 when on wi-fi, but when you want to save battery, turn auto sync off and it doesnt sync ,

I suggest you use switchpro widget. its like the power control widget but with more options to turn on/off things.

I typically charged my Nokia N97 every other day or so, even though I used it frequently, and needless to say the HTC Desire doesn't have the same stamina. I was quite frustrated by it, and I started thinking of ways to save power. I came up with 19 tips, and I have actually noticed quite a difference by following them
19 Tips to Keep the HTC Desire Running a Little Longer

Nice post thanks.ill give this a go. But I have a question to do with the positioning using data or gps. I believe your stating that you should turn data off for this purpose, and let the gps do it? however my phone was set to opposite. when I changed as you were suggesting and I clicked allow gps, I had a message come up saying to turn off to conserve battery? But your saying to turn on? And have data off? Also how do you get into htc facebook settings,i cant even find it!

yep i also use this widget
also use a free juice defender or paid ultimate juice that keeps turning on and off your 3g every now and then depending on how you schedule it, my phone with snowstorm weather widget updating every 80 minutes + 30s of 3g every 5 minutes to update mail etc and average usage lasts about 36 hours which is good enough for me

I leave my WI-FI on at home and suffer hardly any drain.
At work like today leave my Mobile network on down to 47% with just twitter usage!
Pathetic is the mobile signals drain.

Ok, ive had another read of this and am now just even more confused! Are you saying to have gps turned off via settings and location aswell as data, or just having gps on? Are you saying that having gps selected via settings for the purpose of locating services uses les batty than via using data? Either way, it appeatss that the power control widget controls the gps the same as via settings. Right now ive deselected gps and the data location.

I believe this is what I'm saying:
"To let your device learn your location via wireless network triangulation requires less battery than by using the GPS for this purpose. However, using both methods simultaneously is probably not a good idea from a battery point of view. The GPS can handle this task by itself, although it will get a fix on your location a little bit slower. Also, wireless network positioning will be used to collect anonymous Google location data, which will drain the battery further. You can change this option from Settings > Location > Use wireless networks. "
In other words, to only use wireless network positioning will supposedly use less battery than by only using the GPS, but using both methods will naturally use the most juice

For me...
- Turn GPS On when I needed.
- Turn WiFi On when I needed
- Turn Bluetooth On when I needed
- Use 2G Network for standard internet, we use 3G if we want more speed such us watch video

I can get get good days heavy usage (except games) from mine, I haven't tried the 2G thing yet.
Apparently it is the connectivity thing that kills the battery, but turning off 3G, doesn't that take all the fun out of it???
If you just use it as a phone then I reckon you can get a couple of days out of it, or so I've read...
