Hi, this is my first post I have the o2 xda iii, and want to know if it is normal for the phone to go through the whole setup/installation process if the battery of the phone is removed and then inserted again?
Thanks
Hi
The so called "backup battery" should keep your data for a few minutes when main battery is removed.
If you immediately loose date after short main batt absence, your backup battery may be old/damaged.
The backup battery is inexpensive coin-like Ni-MH battery.
Can be user replaceable if you know how to hold a screwdriver
Go to settings -> system -> power and check the backup battery power reading.
my battery was getting low and i knew i wouldnt be able to charge it for a day or two, so i thought id take off the battery to save its little bit of life for a moment when i needed to make a phone call. when i put the battery back in, first it asked me to set date and time, then took me to normal screens, but all my data was gone! contact phone numbers gone, text and picture messages gone. where did they go? can i get them back? its critical data that i cant lose. its been 3 months since this happened. can someone please give me some advice
Your main battery has two parts, one that provides power to the device for normal use and one that provides the power to retain you data for several days.
There is a third battery inside the device but that will only retain the data for 20 minutes or so.
So if you take the battery off for more than 20 minutes then you must first back up your data using something like Sprite.
took off battery
i didnt back up anything. whenever i send or received a message i saved it on the phone. and had several phone numbers saved also. the battery was off the device for a few hours. when i put it back on, it asked me to set time and date and then the main screens came up - but none of my info showed. so can it be retrieved?? i had very very important details on the phone. i was writing a book of poetry and the info was on the phone and i didnt back anything up. i only had the phone a week and wasnt aware of how the phone worked in regards to saving data any other way except for on the phone itself. do i have any h0pe to retrieve my data?
No, everything has gone.
u should have kept the battery in there.
WM2003 keeps a portion of the battery to keep the data safe for 72h
so, in future, dont take the battery out.instead switch on the flight mode and mute the volume
then, store it
better, make a back up
Hi guys,
I have updated my Qtek 9090 to WM5. But I found an annoying problem, every time when I plug out the battery, for example to change the SIM card, the date information will lose and I must set it again when I turn it on.
Does anybody have good idea to solve this small problem?
BR,
Peter

What is the status of your backup battery.
Is it fully charged before AND after you change the battery.
If after changing the main battery the system reports the backup battery to be discharged, maybe your backup battery is died?
Mine does the same thing. I think our back up batteries are dead. How does one replace the battery?
the date and time gets erased every time i change batteries. quickest way to get the time/date right is to connect the xda2s to the computer via activesync (or manually correct it)
I have checked the status of the backup battery from WM5 battery information, it is 100% full. Is this information believable or not? If not, does anybody know how to change the backup battery?

What % is the backup battery after you change your main battery.
Thats the key, if it says it is flat after change then your backup battery is not holding charge.
To change it I believe would entail opening your pda case and removing the old battery & installing a new battery of the same type/rate.
Don't know if they are soldered or clipped in, someone with more knowledge may shed some light.
i use the ms activesync to synchronize the date
i have the same problem.. even if i poke the soft reset button, time and date reverts to default.. september 1, 2004..
i can assure that my back up battery still works.. it loses charge and drains (my ramdisk gets wiped out) for about 30 minutes without the main batt..
I'm having the same problem as well.
Anyone found a solution to this yet?
EDITED:
I'm using Helmi_BA_WM2k5_AKU3.5_v1.4.CF2 R2
And I've confirmed this problem doesn't occur when using WM2003SE.

I have no problem with that, and i am using the same rom as you.
When i remove teh battery, first i lock the device, and turn it off, making the screen all black. now i remove it, and in less than 20 secs i swap cards.
No mem loss.
When you mean by "turning it off", you meant pressing the power button and it goes to suspend mode right?
Cuz on my Dell X51v there's a function to perform a full poweroff which I can't find in this ROM.
anyone tried to remove the battery the moment just after choosing a soft reset?
1. choose soft reset
2. then when the four colored lines come out, take out the battery
3. insert new battery
4. turn on the power
5. just in case the R and G values display "NONE", just choose soft reset again
i think it's a good alternative to keep the date/time after changing batteries... i just don't know the harmful ramifications in doing so, if any...

Of course.
Ok, this is strange.
I accidentally moved the battery latch when the screen was on, the battery fell out and the screen faded out quickly. But when I put the battery back in and reboot the device, all settings including date & time were still there!
So I tried the same method when swapping to my other battery and it worked as well! w00tz!
Done it a few times now with 100% success so far.
Drifter
I use Drifter by Kopsis when I'm in wi-fi range. Drifter uses Network Time Protocol (NTP) to set the time. Thus you can set the time even without syncing to your computer.
I'm using AKU 3.5.2 with the BuildOS on default settings and i can change my battery just fine.
Guys.. how to show the status of the backup battery?
any registry edit?
thanks guys..
running 6.5 os
I guess there is no way to show that status on WM 6.5. For me, I never saw anything like that in the roms I tested, till now.
The only way to say that it is damaged, is when you change the sim or the main battery and the device does a hr after inserting the main bat back in!
The backup battery should keep the device alive, at least for a few seconds to change the sim or the main battery, in all other cases it would be shown as 100% working, as it should do. Sometime the ramdisk is erased after running out of power, which might be a sign for a worn out backup battery.
This could only be prevented by keeping the main battery at a good power level, shutting down the device earlier by using proggis like batti.exe or changing the backup battery. But be carefull: You won't be the first to brick your hima!
Sometimes it hard to find the right battery, you can use the same as for the BA, I read somewhere arround here.
tnx.. muckelmaus..
hope some they there is a solution..
use software
Use Batti you will get to know your backup battery status then.
tnx.. guyz..
Hello all,
I tried to install Cyanogenmod 6 as shown here Also made a nandroid backup when i flashed 2.2.1 (from 2.1). Then i tried to install cyanogenmod, but it problably went wrong there. After getting in a boot loop i rolled back the backup made from 2.2.1. When i started my phone i noticed that my battery status was unknown. Tried to install 2.1 again, looking on the interwebs didn't answer my question also. So who can help me?
I can see the battery level in Settings -> Phone Information -> Another page -> Battery level.
Did a wipe /data/battd
Copied thisin /data/system/batterystats.bin and thought that i saw a good battery for a second, so it looks the phone is generating a corrupt one.
It happened to me when I my batt got wet!
I had to buy a new one.
Your case seems different. But have no ideia how to solve it.
I am having the same problem with the LG P500.
Is the original battery?
Sometimes if its a "generic" one it does that thing.
You may try deleting the batterystats in the sdcard.
Or try the battery calibration.
I believe it was:
Connect the charger, reboot/shutdown the phone, when the screen turns off remove the battery, it shoud turn on without it and it will show "no sim" or similar, then plug the battery.
