Can anybody tell me how strong a drain on the battery Bluetooth will have if it's simply left on but not being used? I usually just leave Bluetooth on all the time even if I don't have my headset with me...will this kill the battery? Everything I've read in the past indicates that Bluetooth in this state isn't much of a battery drain at all.
Thanks!
Not By me.
I have BT on all the time and go throught two full days of usage.

I've always made a lot of thorough battery consumption tests. In new(er) HTC devices, BT battery drain has been a non-issue.
Please also see my articles - I've published a LOT of info on all these (and similar) q's.
Thanks Menneisyys!
Also no problem here.
I also use A2DP alot when at work and usually still don't need to charge the device at all. Sometimes it will sit in it's sync cradle and get a extra battery life but I'm usually not at my desk long. If you were to leave it on discovery mode it will use a little extra but the BT chips nowadays are excellent for minimal battery consumtion/power drain.
I also use a BT carkit which I guess I'm connected to for about 1 hour each day and still see no major battery drop. My old JasJar used to have to be charged upto twice a day with all the above use.
I've had the TyTN now for over 1 month and never had to shut it down due to low battery.

Let me disagree. I've also thoroughly tested this and found no difference. (See my power & battery consumption-related articles.)
That is, you can safely leave BT discoverability on.
Let me repeat that again,
"it will use a little extra" not LOADS extra but a little. I'm pretty sure of that but I agree with you that you will probably not see much difference in general use, just thought I'd mention it.
Just think though - you will be broadcasting/transmitting BT identity information when in discovery mode which you were not when discovery was off.

Hi,
In the last month or two my battery is losing capacity. I can drain out the battery in half a day, when I am working a lot on Athena, for example HSDPA, reboot, phone calls (1h),... but this was not a case before. Usually with “normal” usage I could get the Athena running for a couple of days (3, sometimes 4). Now, when watching a movie or making a phone call the battery drains out about 10 to 20% in couple of minutes. Sometimes it goes from 30% to 5% in just a few minutes. Yes, BT is on always, Wifi amost never. I turn off the data connection completely when I stop using it. All in all the battery is new empty in a day or in a day and a half.
I am really handling my battery with care – so I think. I usually charge it when it is almost or completely drain out and then charge it fully. Athena is 1.5years old with OEM battery.
Is there any way to check the battery capacity or a application which will monitor consumption (or a electrical current)? (I think I read somewhere of such a application??). What do you suggest?
Thx,
Uros
P.s. A recently switched from irus 0mb PP ROM to michy's 4.1 ROM. I find no difference in battery consumption...
Is it possible some application is turning on Wifi or GPS? Either will kill the battery within hours.
However, with 1.5 years on the battery I think your problem is age. I think others on here have had issues after a year. I'm coming up on a year next month and already notice a slight decrease in capacity. Try buying a new battery, worst case you have it as a spare.
Trying to figure out 1) cause of battery drain and 2) poor power mgmt.
I had a fully charged phone yesterday at 5pm, leaving work.
When I tried to turn it on this morning it was completely, completely drained.
I have 4min timeouts set on the phone for backlight off, and 5min for device off when on battery. I had WiFi tuned off, Bluetooth on.
I did have Wayfinder and GPS active on the way home, and may have just turned off the phone. If I turn off the phone with Wayfinder active, would this continue to drain the battery, GPS reception is passive, is it not ???
How come the battery drained to such an exent, it took 5 min on a charger before it would even power up, from a full reset and WM load.
My old XDA would hibernate at low battery percentage, and still have a reserve charge to keep the phone content/settings intact.
Any views, suggestions.

When I first got my x1 end of last year, I found I only got around 6 hours out of a battery.
Now I get about 36 hours of normal use out of one charge. Including 1 hour of gps each day/ half hour of wifi.
What worked for me was to, reduce back light time to 10 seconds when standalone. I also found S2U unlock drained the battery, so I now use the standard unlock.
Also, ensure that no auto updates (only manual) are done e.g SPB weather, insight RSS etc.
I have also changed my battery to a Mugen 1800 mAh. This seems to have increased my time by around 25% on average use.
S2U2 no longer drains my battery, one of the old versions did and so did the old version of AE Button but they are both good now, I get min of 2 days and max of about 5 depending on load of use... normal use is about 3... (internet for emails and dling rss feeds and some reading of forums 1 hour, reading books/texts about 4-5 hours and listening about 2hours plus calls and texts is a normal day for me...)
GPS does drain your battery pretty quick though...

There is no poor power management in there.
It is all because of wayfinder. GPS is still active if you leave Wayfinder active all the time and it will drain the battery supoerfat.
Try closing Wayfinder and you will what I am talking about.
I found out that any Battery applications greatly reduces my (juridically - my wife's) X1i lifetime.
AFAIK to measure any battery charge you need to short circuit it for a millisecond or so and measure the current, not the voltage. When any Battery software does it (through the hardware) every few seconds your battery looses its charge faster.

I am running Home++ and its fairly decent as far as drain goes... I dont notice much more than when its not running...
Tks for all your feedback.
I am fairly ok with normal use and battery life.
In this particular instance the drain happened so fast, overnight, and I was not using the X1 at all. (or so I thought so).
So I am curious to know what caused the rapid drain, and why the X1 does not have a more controlled low power close down.

I have already explained. It was the GPS application that drained the battery, nothing else.
Just as a test try leaving it for as few hours running again and you will see.
battery drain
I do have the same effect. but I do not use GPS or wifi at all.
Sometimes it put the phone down, screen disabled and fully charged. No application running.
Next morning the battery is dead.
It happens about once every two weeks without any sign why...
My solution: I bought a desktop charger which is able to charge a second battery and simply exchange it, when this happens again.
Not ideal - but right now we seem to have to life with it.
do you have an old version of S2U2 or AE Button plus on your phone? And I have also read that batti used to cause drain problems... this might be the case with yours(?) if you have none of these installed then I am of not much help...
If u use Push email or active sync, Google sync Hotmail sync any Email sync on arrivel option ur battery will only last 5hours cause the phone is using mobile web at all times and constantly sending and recieving, turn it off an ur phone will last over 19hours with out charge... EG i turned my email sync off at 10am an the batt level was 60% didnt charge it till next day 11am when the batt levels drop to 20%
Is your X1 fairly new?
I experienced exactly this issue about a week after I bought my X1. No apparent reason for it, but the battery just drained right out overnight.
Strangely, the same thing happend about a week after I bought a HTC Touch Pro.
In both instances it has happened only the one time. Since then things have been normal, or drains caused by known software issues (like the buggy version of S2U2).
As earlier suggested, I loaded the Wayfinder app, with its GPS active.
I tuned off the phone when the app was on screen.
Left it for 3 hours, and there was a noticeable drain of the battery.
Lets hope the new WM 6.5 improves Power Mgmt, and has a more elegant low power handling.
Do you have G-Alarm installed? My Battery gets drained very fast when I have this installed. I tried many different versions within the last few month, allways the same.
I experienced this last night for the first time with my X1. I left the X1 on the bedside table at 11:30 with 90% charge and was awakened by the battery low alarm at 6:30 am (not good).
The only thing that I noticed that was unusual was that my X1 had been connected to the PC with ActiveSync in the connected state. I shut down the PC and then unplugged the X1. In the morning after the battery low alarm I noticed that the phone thought it was still connected. I use SPB Phone Suite and it was still showing the Cradle profile. This would not change in the automatic mode so I had to reboot the phone. Everything has been fine since.
So ... I am wondering if ActiveSync can sometimes go crazy and drain the battery more quickly??
I have a faster draining battery since i installed g-alarm. can anyone confirm that?
In my case I dont have G-Alarm installed.
Well my battery is not draining that seriously. it's ok i guess.
But maybe you should try what is suggested in the last post of this thread:

Deep discharge my X1-battery just almost doubled my battery life in average

I have been using G-Alarm since the very moment I got my X1 and there is no noticeable battery drain. Lasts 3-4days.
Hello,
Sir like many others, I too have a battery problem with my SPV M3100
The battery always shows it's status in the 10s. Which means like..
90%, 80%, 70%, ...
It never shows up something else then tens which is not really good.
The second problem. If the battery is 100% charged, I open WIFI in few seconds it will drain to 90% and 80% and then 70%.. It drains really very fast. I know that WIFI eats up the battery but not like 10% in 1 minute???
Third problem, If I keep my mobile 100% battery on stand by mode and I don't get a call. After 24 hours I go and see it will show and battery left 100%. But if I go and do a small task in mobile, it will drain like 30% in once. That is quite ammazing I have never played on music so can't say how much it drains while playing music on hands free.
Overall on standby mode, the battery lasts like 3 to 4 days. But if you use it for even a small thing, it drains really fast and battery was dead.
Please help, I think this all is not normal, Radio version can be the reason of this???
Thank you very much
Faisal
i have too this problem, if you find any way for solve this plz help me
I have the same problem..
Even when I go online with GPRS/3G/UMTS/HSDPA..
Does the problem come from the battery?
My battery has UTSTARCOM text on the battery. How about you?
EDIT : You need to flash a ROM with a 1% increment fix, it's because the stock/official ROM has 10% increment battery meter, I don't know why.. And my battery drains very fast because I have over-charging it.. I leave my Hermes charging overnight when I'm sleeping, and it leads to over-charging.. You need to unplug the charging cable when the charging complete ASAP..
I have the same problem on my Spv m3100. The power meter deplete at 10% increments. Unlike my HTC TyTyn 2 - Kaiser this shows actual units.
I know the battery life is already pretty bad, but what are your experiences with battery life and bluetooth.
I will keep it in my pocket connected to bluetooth headset, without using the phone much.
Is the battery drain fast or is it slower?
In your estimation how much battery life do you get with bluetooth on listening to music.

it will drain faster obviously but there is nothing to worry about. For example i lose around 10 percent after 2 hours of music with a wired headset

I feel like the cover is going to break off, since putting in my pocket is not as easy as I would like.
It's always in the way and never flush, I'm using an L shaped cable.
I need maybe 5 hours max of music.
2 hours on bus to school, 2 hours back.
I can always have it charged while at school.
Should be able to get enough.
Everything you turn on will drain battery, but my phone is every day the whole day in my pocket, while connected to Bluetooth hands free in car and connected to TomTom navi using Bluetooth tether (for getting real-time traffic info on my data connection) and I'm pretty satisfied with battery life.
At the and of a whole day ive got still left 70%.
