What do you think uses more power, using the build-in GPS or use BT and an external GPS? As i have an external HOLUX, I'm not sure wether to use it or sell it...
If nobody knows or have measured that.. is there a way to find out how many mAh the GPS/BT uses?
Quite easily the BT with an external gps will use much less power from the phone.
in my exp the built in gps drains alittle more batter than bluetooth, but it all depends, there is many factor that changes battery drain, so you will have to play around with it to find the best that works for u.
factors to look out for is how well your battery holds charge, the radio your using, screen brightness.
don't forget that you'll have two devices to charge if you use the ext GPS reciever.

My Qtek2020 is linked to a bluetooth headset and the bluetooth setting is "on"; i was very surprised that after a full day outside after roughly 6 or 7hours, the battery which was full showed almost a total depletion of energy; Is there any way to get an "automatic" bluetooth mode on the Qtek2020 that would switch the bluetooth on only when needed or requested by the qTEK when an incoming phone is directed to the bluetooth headset or any way to implement bluettoth energy saving modes, as was done on the Spve200 or Qtek8080 by the people of Modaco; I also own a Spve200 and the tweaking of bluetooth modes they implemented is rather efficent and energy saving
Awaiting yourinput and tweaks for our <qtek2020 IMate, Mda2, i remain, Arnaud
Get a new battery. I have BT on 24/7 and charge twice a day, at most....
Thanks, i have already ordered two and i'm waiting for the delivery; You say you charge at most 2 times a day, could you tell me the time that elapses in bluetooth use from the first full charge until the battery low indication appears for the first time on the headset so i can have a better idea of the ranking of mine? Could you also tell me if your mobile network uses 1800 or 900 MHZ, because that could have a certain importance; Fyi Bouygues Telecom, one of my french networks, is a full 1800 mhz network;
Thanking you in advance, i remain

No idea if my mobile network is 900 or 1800 MHz, i'm on T-mobil ein Holland...
I never see the battery low indicator ! In standby i app. use 20% of the battery in 4 hours... So full changed in the morning, of to work (in the car on charger) and afre 8-9 huors on 50-60% And back home in the car on the charger...
Update :
Last nigh at 01:00 batterystate was at 92%
I left the device on the table with BT on.
Switched my HBH-35 BT headset off.
This morning at 10:00 the batterystat was at 78% !!
So on standby only 24% in 9 hours !!
Dunno if the XDA/MDA II uses more power if the Headset is switched on...
Does the XDA/MDA II keep a connection with a paired headset that is withing range ?
Battery Depletion/XDA1 plugin 1200mah batterypack on XDA2?
Thankyou very much for your continuous follow-up of this topic; I imagine that when both the Xda2 and the bluetooth headset are on , the energy drawn is higher than when only the Xda2 is on, as i think, but am not sure, that the bonded devices keep regurlarly interrogating each other to find about their whereabouts; But again that is pure supposition.
What i have noticed is that on my Qtek2020, with a full night's charge with the radio part off as well as the pda part off, Omega's one Battery indicator shows a figure around 7hours of available usage; When i switch the bluetooth headset and the bluetooth headset profile on the phone and hold a few conversations, lasting, let's say 30 min max, the indicated figure is pretty much close to 3 hours or so;
One good point is that if i put the phone on the craddle to charge-it , the the figure climbs , after also roughly 30 minutes ,to 5 available hours and still rising;
Are these figures in bluetooth headset bonded mode normal and close to normality or are these figures abnormal; If the latter case, what can be done to regenerate the battery while i wait for the additionnal ones i have ordered?
Last question: Tmobile' site offers also the former Xda1 batterypack and states that is compatible with XDA2; Is this the case, as this could also be a working solution to enhance the battery lifetime when you are away from your battery charger or craddle;
Thanking you in advance, once again, for all your valuable time and useful informations, i remain, Brgds, Arnaud

No problem, any other day you might be able to help me instead, that's what is board is all about. Users helping users.... Because the company's don't, i might add :roll:

I expect the same, since the batt. useage is higer at daytime. but that might also be because i'm not fetching mail and adding apointments at night :lol:

Ditch the remaining battery useage time, it sucks, even after chargeing it managed tot show a _lower_ usage then before ! juts look at the percentage, and *know* how long it will last in stanby...

Ofcourse, but i'd rather go for the XDA/MDA II Backpack and get a CF-slot and VGA-out as an extra !! :lol: Afaik it costs € 170,= (app. $ 150,= ?)
Well if you are getting 5 hours on the battery, that is great, mine at 100% charge, phone on but NO BT, shows only 3 hours and this rapidly climbs down during the course of the day. Is this normal? Cause I have to charge it once again every evening around 4 pm to make it through the day till I hit bed.
The no# of hours remaining is an average on the past usage of the battery. Hence, i don't trust the figure...
Uses battery
bt uses a lot of battery!
Hello everybody
How many hours (aproximately) it takes to drain battery when using gps on xda with integrated gps (like artemis, mio a701 etc.)?
It's possible to take a 8-10 hours trip with bike and turned on gps on the xda? Would it last that long?
No way.
Depending on how you set up your device, and depending on a specific phone you may get 4, 5 hours tops.
That's provided you do not use BT / WIFI at the same time, don't talk on the phone and keep the backlight down.
Also if you really want to maximize the battery life you would have to turn the phone off all together (flight mode).
However, you do have the option of carrying extra battery with you. I remember seeing a device (sorry cant remember name or company) that has a 3000+ mAh battery and USB HOST connection. You charge it at home and use it on the road to power / charge any device that takes power through USB cable.
Thanks for replay.
So using pda and gps mouse is better solution, right?
And how long lasts pda with bluetooth turned on? More than 10 hours?
Is it any difference in battery life when using pda with bluetooth 1.2 and one with 2.0? I read on wikipedia that 2.0 consume less energy. Is that true?
Hi,
With my JAMin and a bluetooth GPS I reckon I could maybe push up to nine hours of use, with backlight set to go off after a minute.
I would guess using the inbuilt GPS of the Artemis will reduce this quite a bit.
Regards
I recently went on an 8 day cycle ride with my jamin using tomtom to go from St Malo to Le Cap d'Agde. I have a shimano dyno hub in the front wheel. I set up switch box so that at night it would power the light but during the day would charge my phone.
My GPS lasts about 11hours so only needed charging every otherday. The phone ran on batteries while the gps was charging. Seemed to work quite well except over 30kph when the my regulator seemed to shut down as the voltage was too high for it.
As I had a constant power supply I was also able to play music from the phone to keep me entertained!
I would think this is probably the one levenum mentioned.
Do a search looking for "I-UP3600" this is a small external pack that will power an Artemis for about 6 hours if fully charged, before the Artemis stats to use its own power, very handy gadget. I did read somewhere that they were bring out a larger capacity pack around 5,6A/Hr (the numbers denote the capacity 3,6A/Hr is the one I use), look http://www.busytrade.com/tradeleads/tradeleadsInfo.php?messageID=179864

Found it.
Here is what I was talking about.
Hi,
I'm looking for a Pocket PC windows device to mount on my bicycle - I need to run GPS navigation on the device - GPS receiver can be either built in or on bluetooth.
I need to know which device have best battery life running for example - TomTom or OziExplorer.
Screen size - 2.8" or 3.5" - other functions like GSM, etc - not necessary!
What about - HTC Touch, Touch HD and HTC P3600?
I have been using an HTC P3600 for a few weeks, (Company hand-me-down, replacing a Qtek 9100, (Wizard)).
The battery life on the P3600 is mediocre at best, but abysmal as soon as you start using GPS. It is possible to flatten it completely in under an hour! Even a simple Win32 program that I wrote to just read and display the WGS84 Lat/Long coordinates, no fancy map displays, still canes it. It seems just the act of turning on the GPS com port, which powers up the GPS unit, is responsible for the power drain. The battery may be on its way out, until I find a replacement the jury is still out.
I reckon you could struggle without some extra power, external battery or some regulated supply from a dynamo or similar.
Can't vouch for the newer HTC offerings, anyone else?
what i would do is get a tmobile wing with extended battery an an external gps unit. it would run all day and all night.
Polaris has a wonderful power consumption in my opinion.
Definitely use a bluetooth GPS, it'll take a lot of the strain off. As for battery usage with GPS Navigation, that's a good question. I've never measured the power usage differences between the programs I use; iGO8 and TomTom.
Bad part about the bicycle is you'll need to crank the backlight up, and that's a major killer. Where backlight is at 0% (on, but lowest) being 0 mA of usage, 40% backlight was 54mA and 100% backlight was 123mA on my Tilt. That means that going from the backlight dimmed completely to 100% adds 123mA of battery on top of what you're already doing. In case anyone asks, I say 0% = 0mA, because I did measurements relative to the backlight being all the way down. How many mA the backlight uses at its lowest setting, who knows. I didn't care for what information I wanted from the measurements.
Have you considered a PNA? At least if the batteries go dead, you can still make a call and you can still figure out where to go.
why would you need maximum backlight tho... you can use G-light to adjust backlight automatically and save battery..
and if you cycle at night.. minimum backlight is enough.
Hello,
Why does having bluetooth on drain my battery so much? I used to keep it on for my old phone so I wouldn't have to touch anything when I got in the car making it extremely convenient for me. Is there a way around this that some of you guys use besides a widget where you click on it to toggle bluetooth?
Thanks for the help. Please excuse my noob-ness. First time Android user here! Cheers!
bump.
anyone?
I am investigating the issue myself just now. And I reached a conclusion: the Android battery info chart is misleading. It shows the percentage of time the bluetooth or other devices (like display) are actually on, not the percentage of battery really used.
I used an application to switch the BT on every few minutes and the real battery drain was a nightmare. Now I have been testing it with the BT always on AND connected for nearly 6h. Made few phone calls via bluetooth . Attached are the results. Which are quite good in my opinion. At least compared with before.
PS: nothing. The attachments are not working. Still 19% of battery used in 6 h.
So strange. Thanks for posting your results! Hopefully I can just root it and leave my bluetooth on
Why rooting? It isn't necessary. Just leave the BT on. It has been few days now and I didn't see any difference. Which makes sense thinking about it. The PS3 controllers communicate constantly via BT and they last forever. And they have the mechanical rumble. Again, it's just the battery info that is totally misleading.It should report values on the range 0-100% for the time the devices have been active.
so.. do they use battery if they are on but not used? i have read yes and no. do they use battery if on but not used?
I leave both on and my battery life is great.
Install a battery monitor app (the one that provide how long your battery going to last), when you enabled gps, it showed a 2 hrs drop from the total, so the answer is yes even without using it. A big surprise between wifi and 4g, they consummed almost the same power, only 10min less from the wifi.
Yes.
GPS still tracks where you are for apps running in the background (e.g. Google Now).
Wifi is constantly searching for a connection when on. Staying connected to wifi also takes battery.
I have extensively compared both running with the GPS on all the time & never using it at all.
It made virtually no difference whatever in my battery life (unless it's actually doing something which is infrequent, it really uses no battery at all), so I leave it on 24/7.
I have done this in phones all the way back to my DroidX & don't give it a second thought at this point.
Also tried many tests to see if wifi and gps on/off makes a difference. Almost none, leave them on, even BT left on didnt' make much difference.
