Battery Recalibration

I've purchased a second hand xda2, and found (not entirely to my suprise) that the battery life wasn't great - typically less than a day even if it had sit in the charging cradle the previous night.
So i went to o2 shop yesterday lunch time and purchased a new battery. They charged it for me on a rapid charger - took 30 minutes. However by the time I got home at 8.30pm the XDA2 was reporting very low battery - this is the new one - So I put that down to the rapid charger and I fully charged that one over night last night and took it out of the cradle at about 8 this morning.
It's already reporting 57% percent battery.
Now ok, i'm aware I've been using BT a lot to sort my active sync this morning etc, but surely battery life should be better than this? I used to have an IPAQ and that needed recalibrating because it was incorrect at guessing how quickly the battery would drain. Does this happen with the XDAs? if so how can I recalibrate or is something else likely to be draining the batt?
Thanks
Anthony

well the manual say you have to charge it for 24hours or so the first time
i would try to do that
also look if it's the normal batt or backup batt which is complaining
otherwise the batt life should inc the more times you charge it

Ok i'll try leaving it in the cradle over the weekend and switch back to my normal phone - backup battery is 100%. My old battery is in the aux battery holder in the cradle and has been since 1.30 this morning so maybe tommorow i'll give that one a whirl again!
Thanks

Try it with bluetooth switched off for a day and see if you get a different result. The other possibility is if you're in a low coverage area and your phone is constantly polling for network availability - is this likely to be the case?
If none of these apply, are you running any other peripherals, e.g. SD Wireless card? Just trying to whittle down the possibilities before blaming the hardware.

also upgrading to 1.72 should help.

Make sure that you don't have the Blackberry Software running unless yoou're using Blackberry ! (Check the taskbar for an envelope icon). If you do run it, and you're not connected / subscribed to a Blackberry service then you'll get less than 12 hours on your battery.

Tytn / Vario II Battery

Hey again,
Had my vario for a couple of months now, but really getting annoyed with the battery now...
Charged it to full in the car this morning (11am ish) and now 15:30 it's dead.
It does have push mail enabled and has received around 20 emails, but surely this should kill the battery by then.. I wouldnt mind, but have been at the pc, so havent even switched the screen on....
any comments / advice?

I'm having the same problem with mine. Does the battery pack feel really warm even when it's not charging and just on standby. This is my second Vario, the first had a faulty keyboard latch, but the battery didn't get hot and it lasted for days on standby.

Its the Edge/UMTS/3G chip..
I had the same problems.
Since I switched to GPRSW instead of UMTS/Edge/3G connection my battery will do twice as long. Search for the free tool "BandSwitch" on these forums and you will find a solution to switch between GPRS and 3G without a hassle...

Hmm... whilst that may work, it's one of the reasons I got the Vario is that it has 3g bandwidth, so to disable it to have more than a couple of hours batter seems crazy.....

Well it's a balance - the idea is not to disable it altogether but to switch it on when needed but not keep it on routinely. For example much of what I do does not need the bandwith and so it's only needed from time to time.

have had a look at the running processes, and has been running nothing today, still a pants battery.
As for the rom, am a bit dubious, as if I do that and it turns out to be a hardware problem, then surely that would void my warrenty?

mine also feels warm when on standy. not using andy wifi bt or g3 or highspeed just the phone on standby. Only have had the thing work and hold charge and run cool a few times since I have it. Battery drains in a matter of 6-8 hours

Still loose 2% battery per hour, Vista off and WM in sleep mode

As I loose that much per hour, I was wondering if that is abnormal.
I hard a n d softreset WM, have no SIM card in, just do NOT use WM.
Vista is fully switched off.
Pls tell me if that is normal and, if not, what to do .
Still interested in that miracle tool to switch WM off fully. I do not use it.
Huib

Yes it is abnormal! My Shift still has 92% battery life after 36+ hours (Radio off, WM sleeping, Vista off). I don't even get anywhere near 2% per hour with Vista booted but sleeping (more like 1%).
As I said before in your last thread on this subject, I think there is a specific problem with you device - I get about 2 hours from my Shift when Vista is awake, so I don't think my device is "special".

Dave

Sleeping? Or Hibernated? If you only drain 1% per hour in sleep maybe i will extend the time-to-hibernate in my profile to a few hours. Waking up from hibernate is fast - waiting for all the applications to get back to "normal" speed however takes like 3 minutes. So freakin annoying. Anyone else have this problem?

Neither sleeping, nor Hibernating Vista. Switched off! But WM of course.....
-------------
So:
My Vista is fully switched off.
I would be happy if I could get more statistics from your guys.
Pls switch Vista off on a fully loaded Shift.
Put it next to the bed, and see in the morning ( Lets say 8 hours) if it has more or less then, lets say, 85% power left.
-------------
Of course, as told so many times, when I take out the battery and put it back, there is no powerdrain at all ,because WM has not been started in that case.

Hello again Dave,
You are right, but I was wondering if I was the only one, that's why this new thread.
Can you tell me how you set WM to sleep?
I have of course this "turned off if not used for 1 minute"
Shall I switch flight mode ON in the shagctrl? So turning off also my WIFI?
Coudl WIFI be the killer? Even when Vista is fully off? Did not try that yet, but I certainly will now.
And... How do I switch WIFI off, when not in Vista as as there is no Shagctrl.
Huib

well your problem seems like my problem
I have the same problem like your shift
my battery also drain about 1-2% per hour even without using it (I leave it at my side when I sleep)
Up until now, I still don't get the reason why this happening
Because, when I first time got the device, it was last longer than that, I saw it just maybe drain up to 15% for 2 and a half days

Yep,
Till now only Dave does not have this problem.
I just tested with WIFI off, and same problem. There is no realation and should not be.
Especially when flying it is a problem, because then I really am without juice. I bought an extra battery however, but still.
So I (sigh) take the battery off and put it back quickly. That solves it
Huib

yes and I think right now the snapvue can't take the wifi out to work, so it doesn't have a chance to reduce the battery
Well, if you said only Dave, I think, mine at the first time doesn't have this problem
At the first time the shift was at my hand , it can last for maybe 4days without using it
Strange isn't it

Hmm. @Herpi.
In this Thread
http://forum.xda-developers.com/showthread.php?t=389487
i found out:
If you run only SnapVue, and go off ... battery drain is normal 5mA/h for SnapVue standby.
Now ... if you start up Vista - do something like usb conection to resync, an shut vista down at last. SnapVue drains now 40-50!!! mA/h in standby.
(by comparison: in WM6 200mA/H in Vista 800-1000mA/H if backlight is 2.th low)
A softreset solves the problem - till you start up Vista again.

How do I softreset after closing Vista?
Huib

You must liberate your Shift to unlock SnapVue to real WindowsMobile6.
Guide:
http://www.modaco.com/content/windows-mobile-news/266537/liberate-your-htc-shift/
Then you have a "soft reset" programm, but your can use other applications, like taskmanagers (e.g. WK-Task | http://soft.photoracer.net/docs/wktask_en.html ) too.

Well, when I say sleeping - I really mean "not active". Assuming Vista is asleep or shutdown, when I've finished with WM, I press the "shift" button to switch it back to my inactive vista session.
Shall I switch flight mode ON in the shagctrl? So turning off also my WIFI?

Interesting idea - perhaps if Wifi is on, it remains powered up even if Vista has been shut down.

Unfortunately, at present, you can only switch if on and off via Vista.

Sleeping - I found that hibernating doesn't really give me any speed benefits over a cold boot.

Just an FYI, but I've not used my Shift at all since my first posting on this thread, which is now some 50 hours ago. In that time, the battery on my Shift has dropped a further 12%, so I'm now at 80% capacity. This means in the last 86+ hours, my Shift has only consumed 20% of its battery power.

So here comes my call again: anybody else, somewhere on this world ,has this perfect battery consumption as Dave has?
Huib

Yes, my battery consumption is very similar to Daves, I don't seem to be leaking power when not in use. Vista hibernated, Windows Mobile checking 2 email accounts every 15 mins from 7am this morning until now, (5.20 pm), battery now on 92%.
Left unused, with the modem turned off but winmo running, it drops around 6-8% in 24 hours.

Battery running out over night

Hey
My battery is emty every morning, and phone turned off. That is if the battery is under approx. 70-80% in the evening. Is it just a bad battery?
Anybody seen this problem before.
Hex3

Do you turn on the "Microsoft Direct Push" ?
When this feature is turned on, I also appeared that you have encountered a similar situation, but only consumes 40-50%

where can i check that, cant find it!! I have spb 3
Hex3

Look at your "Comm Manager"-"Microsoft Direct Push"

Found it. No its set to off, so thats not it. Maybe ill try a hardreset!
But thanks for the help
Hex3

hello
i have the same problem for 2 or 3 months now and i did not find a solution.
i bought a new battery but it did not help.
did you found a solution?
marbon

There is always a solution
Your device must have enabled the "turn off device" timeout (aka suspend timeout)
Don't let your device check your emails too often (once an hour is more than enough).
Use Advanced Config to enable GPRS disconnection timeout.
Don't let TF3D check for webpages updates too often.
Don't let RSS reader check for updates too often.
If your device has Wifi turned on all night, check if it turns off while your device is in suspend mode.
And of course, carefully choose applications that run in background - some of them may prevent your device from going to suspend mode.
(suspend mode is the most power-saving mode)

no, havent found the solution yet

Simply put your phone on charge and leave it like that for as long as you possibly can for as much of the time as you can.
Do not run a discharge cycle. Do not try to 'condition' the battery and as soon as you can recharge from an available power outlet.
I get 1.5 days from this and I would suggest that you should get the same.

78michel said:
What happen if you switch off your smartphone ( be carefull ....not suspend mode!)? Is the battery still draining?
Have you check the current delivered by your battery during your ''night stand by''?
The objective is to check if there is any extra leakage current in the main circuit board.

It should not be draining when it's off, it's should actually go up (happend to me).

Hi, i have had my TD2 for nearly 2 weeks and last night i had a similar issue, however my phone was not turned off it was in sleep mode.
Charged battery to full at around 5 p.m went and stayed at my girlfriends and when i woke up this morning the battery was dead, came home plugged in the charger and got no charging light.....oh dear i thought.
So i removed the battery and the sim blew on the contacts etc to remove any possible dust put it back together and now i get a charging light and all seems to be charging ok.
The only thing i did different yesterday was that i went on google maps for the first time and selected the use gps option so it was seeking satellites, when i exited google maps i made sure it was not running in the background.
Im just wondering wether it was still using power to search for sattelites as in my information screen in power it says i have had 8 hours standby and 10 hours 52 mins device usage and i know that is not the case.
To the OP >> Maybe check in your google maps to see if you have use gps selected?

I had same problem after I flashed my phone with new radio 4.48.25.13, after that I used some other raido rom and the problem was gone.

I had the same thing happen, but only once, it was after I was using a gps app in the evening, I had problems with it, it locked up and I terminated it instead of closing it, I assume the gps stayed on and drained the battery in short order.

Hi, no i have not turned the GPS in google maps on, so thats not it. Still trying some different things to narrow it down. Its not every night now, so maybe i have been lucky.....

Same story here...
In my case even worst. I got my TD2 last friday morning. The same afternoon I inserted a new microsd card with zorro-gps installed. The day after, while I was driving with the gps turned on, the phone died. I've thought it was running out of battery, but when i plugged the charger in, I could not see the red led turn on. So I had to remove and reinsert the battery in order to see the led work properly...
Unfortunately from that point the phone is not working properly anymore. While in use it dies and I cannot restart unless I remove and reinsert the battery. The problem is that this happens every 10 minutes...
I'm trying to contact the HTC support, but they are very elusive. They asked for my phone number and they said will call me back...
Did you guys try to change the batteries and see what happen?

No, didnt change the battery. Because its not every night i dont think the battery is the problem. And further more, it began about a month ago ( td2 is approx. 3 month)
FedeR1 maybe you should try hard reset!

while i use it i notice the battery produces too much heat that i can notice
the battery can be drained very easily with any action
I just turn off my phone it was 21% charge i noticed the heating issue
and i turned it on again and the battery was 14%

Well, Its normal to get hot when taking a long call.. (10 min or more), but while in standby, it should NEVER get even WARM (mine stays cold as ice ) !!!
The power drain maybe is cuz your phone is heating.. The heat expands circuits and increase the power drain.

I wouldn't rush to send it back. It all sounds normal to me.

You must remember that the batteries will take a few weeks to attain full capacity operation.
Keep them on charge as much as you can (mains or car/plane etc), don't switch off at night, don't cycle them and don't drain them excessively.
If that does not give an improvement THEN take them back.
When I first got my TD2 I was appalled at the battery life and bought a spare battery. I have never used it.
And when they get warm it shows that they are happily being used or recharged and is no cause for concern.

Hi Cairo,
First of all, sorry for my english.
In my case, I bought my TD2 this summer, & I had some of these problems with the battery.
I'll tell you my steps, perhaps it could help you, if not, you must talk with HTC support.
First, use modaco's nodata to disable HSDPA/3G, use only GSM, it's much better to save battery. the link :http://www.modaco.com/content/pocket-pc-software/246171/new-free-utility-nodata/
Second: Active Sync.
You need a task manager to see notifications.
you must find one of the repllog event.
Use this http://www.dotfred.net/TaskMgr.htm.
In notifications tab find "repllog AppRunAfterTimeChange" and disable it.
In my case I have disabled two events more, PushInternetScheduleTimeChanged and PushInternetScheduleTimeChanged1 and everything works fine.
After that, in process tab, if repllog appears, kill it, and in notifications tab find again the event "repllog.exe /remote /h",disable too, and use a reg editor (dot's taskmgr has one) and search in hkcu\software\microsoft\ActiveSync, find "KeepAlive" and you must change 1 to 0.
In this case, activesync will never start again, till you connect td2 to laptop or pc with activesync (it changes the value from 0 to 1).
I hope you could understand me and the info is ok for your td2.
Regards

You need a task manager to see notifications.
you must find one of the repllog event.
Use this http://www.dotfred.net/TaskMgr.htm.
In notifications tab find "repllog AppRunAfterTimeChange" and disable it.
In my case I have disabled two events more, PushInternetScheduleTimeChanged and PushInternetScheduleTimeChanged1 and everything works fine.
.
I hope you could understand me and the info is ok for your td2.
