I've just acquired an O2 branded (from HK) XDA IIs, and when phone powers up I am notified that the backup battery is at 0%.
Leaving the phone charging in its cradle for 2 days and backup battery still shows as 0%.
Have done both soft and hard reset, as well as upgrading to latest radio stack and OS.
Am I now forced to do surgery on this unit and replace the internal backup battery?
Has anyone performed this process on this unit before?
Hints, part numbers etc
I appreciate all help and thank you in advance.
Anyone??
I heard that the backup battery charges from the main battery, try charging the main battery separately on the cradle to full, and then putting the phone+battery on the cradle for charging.
Thanks for the suggestion Sandy.
However, the problem persists.
I've even tried putting the phone on the cradle without the main battery to see if this would force a backup battery charge. The charging light stays red, and after a couple of hours, backup battery status still says 0% (so it's not a sensor issue), and if you remove main battery, it continues to be the same as a hardware reset.
On a positive note, xbackup seems to restore things quite well.
Can anyone else think of any good ideals?
The error message on boot-up emphasizes the problem
"To prevent possible data loss, replace or recharge your battery according to the owner's manual"
I find no such instructions in my owner's manual.
Maybe you can try to replace your backup battery with new one.
If anyone has instructions on how to replace a backup battery I'd be more than interested in trying it myself.
I am however under the impression that this involves 'opening' up the unit, using special tools and disassembly procedures, and I'd rather hope to follow someone else's instructions than bravely go where no man has gone before...
If only we had a service manual for these models...

"special tools" are Torx5 and Torx6
screwdrivers. "disassembly procedure"
is surprisingly simple, you only need to
be careful when removing the keyboard cable from the mainboard. I'll take the photos when my
replacement LCD will arrive.
CR2, it sounds to me like there may be some good news on the horizon. Do you have a time table as to when you expect to receive your replacement parts.
The young lady whom I purchased the unit from is more than willing to reverse the transaction, and I believe she should be held up as a role model of a good ebay seller.
If there is a chance that this unit is salvageable, I'd be more than willing to go through with the purchase if the repair can be made with my limited skills.
Let me know when you expect to receive your new LCD, or if you can provide any additional hints on the repair procedure. I guess if we knew the replacement battery part number I could start to source from local suppliers.
Anxiously awaiting a positive outcome to this situation.

Hi guy,
I've got the same problem ...backup battery seems doesn't work, I tried everything...and now I think there's only a way...change it!!
I'm going to purchase the component on the web-page you linked here...
I hope someone can tell us or show us how disassemble our blue angel...a tutorial o something like that.
bye bye
wondering, last night i forgot to charge the Universal, this morning it was off.
Plugged in the mains and booted the universal, all fine. Then i checked battery status and it was charching nicely.
Now my question, never checked it out and couldn't find anything in the forum so i am wondering :
is there no backup battery? it does not show in my battery settings. if it is not there is the universal the first one without? LOL
or does it show the backup battery only after the main removable battery is fully charged?
I also noticed it retained all my settings etc, my qtek s100 would have resetted already??
Greetz
DvL
:twisted:
there is no backup battery, the ram isnt volitile anymore its persistant, hence, no need for backup.
one of the BIG +'s for WM5
hehe
:shock:
wow didn't even know that when i bought my universal LOL
ok i will never sell it now haha. anyone wanna buy a almost new qtek s100? hehe pick up only LOL
i really can't believe those people saying they prefer their mda's 1 2 3 compact now.. they are so outdated LOL
EXEC backup battery
I have just purchased a XDA EXEC on an O2 contract and in one of the instruction books supplied it mentions that there is both a lithium battery (the normal phone battery) and a NiMH button cell inside?
I have not seen any indication of this battery on the system information on the phone itself.
The switch you flick to get the battery out on this and the previous XDA's activated the backup battery on the XDA2, 2i and 2s.
Perhaps we have the same switch but no backup battery inside?
There is no backup battery, cause the Universal doesn't need it. *period*!
It's a new concept with persistent memory. No need for a backup battery (which will last only a limited time), cause memory content is save. It's just flash memory as in the sd-cards, which don't need any battery, too! :shock:
So no backup battery in Universal is an advantage not any disadvantage! :shock:
Got it now?
I dont know if this is common, but my XDA IIs hard resets itself even when I remove the battery momentarily to change sim card. This happens even when the device has just been removed from the charger after having been there for ages (just in case ;-) ).
This is majorly annoying since it means I cannot swap sim cards away from my PC (since a restore is necessary afterwards). I know I can restore from my phone, dont tell me that, its the useless internal battery that bothers me.
I agree!
If the battery is out for about 6 seconds, it's done!
Or, the unit is ON, and the battery falls out... INSTANTLY!
Terrible!
Dumbest design I have ever seen!
The most annoying thing is that when i was trying to do a hard reset once by removing the battery, it wouldnt go! It lasted its full quoted 20 minutes!
I suppose youve just gotta be prepared with a fresh backup beforehand, grrr.
The internal battery is so that it doesn't do a hard reset and wipe everything off of the volatile memory when you pop the battery out; it's not designed to keep your device on when you pop the battery off.
I know that, but it doesnt even do what you said.. (most of the time)

I haven't had a problem with mine; I can keep it out for a few minutes without issue.
Hi:
When I turn on Flight Mode (the phone is off) and when I close all programs before removing the battery, my PDA2K just does a soft reset, not a hard one.
Hope this helps.

Try to check if the backup battery works right... I had this kind of problem when my backup battery didn't work...
Yes, same thing happens with me. This has one permanent solution, upgrade to WM5.

help replacing backup battery
Hello all, I need help replacing the backup battery, and, what type is it?
moving house again, cant find the book.
Also from my previouse Psion Organiser days it was always better useing NEWS PAPER to clean the battery BUT DONT TOUCH IT! use plastic tweezers if you can, and clean the inner contacts with news paper or similar.

It's a boggo standard lithium cell, maxell 1602 or summat, 3v w/tags costs about 3? Open the unit up, peel back the conductive tape, remove the shielding and it's out.

Hi Guys,
Whenever I remove the battery from my XDA 2S I lose everything and have to set up the OS from scratch.
I have spoken to O2 and they have told me this is normal? But how can this be? It is the most stupid thing I have ever heard.
Please if someone could just tell me if their XDA 2S does this I would be more than grateful!
Thanks in advance.
Jonnycash!
Go to settings/ Power icon and check the status of both the Main Battery and the backup Battery, the first could be at any charge % the backup Battery should be at 100%, this is used to hold the data on the phone for a short duration, sim card swap or battery swap with the machine selected OFF first. If its loosing data then there is something wrong with it, I can remove the Battery on my IIs for 10 mins if need be without a problem - Mike
Yes the Backup Battery is at 100%
It loses everything as soon as I take the battery out, I can put the battery straight back on, start the phone and OS setup begins.
When you say selected "off". Do you mean quickly pushing the power button once.
I have done this and still it loses everything.
Looking forward to your response.
Jonnycash!
All I can sugest are two options
1, Return the phone as it is clearly faulty, demand O2 repair the unit or try for an Exec as a replacement as re-compense, you might get this easily as they are no longer offering the IIs.
2, install something like Sprite back-up and configure the back-up to re-install everthing hardly ideal, and this is not what I would do.
Mike
Yes, I have just got it back from being "repaired". they said that they replaced the circuit board but it still does it.
I will send it back as suggested and try get a new one.
Thanks
Jonnycash
After taking out the battery, try not to push the tab(the one you pull back and the battery pops up) that holds the battery back into place until you re-insert the battery.

Sounds like a duff backup battery to me ( see pic), changing the mainboard would seem a sledgehammer to crack a nut. I have had this with blueangels after re-assembly, even with the backupstatus at 100%. I leave on a cradle charging overnight then do a hard reset - seems to work for me.
Richard
i have that problem as well before. but maybe this will help you a bit.
because i always do it removing the battery when changing my sim card. how i wish they would put the sim card away from the battery. ( calling the attention of the engineers for future references).
i started on the permanent save check mostly on contacts and appointments (I needed them all the time) (start>settings>system>permanent save). then i usually turn on the flight mode then turn off the pda from the power button.
thats the time i take the battery off and either to swap the sim card of the battery. then it automatically go to soft reset when the battery is back you will notice that after the automatic soft reset, there will be a small window showing appointments and contacts restoring.
i hope this will help.
I've had this, once. I've heard that this is a bug of that little black thingey that holds the battery, because it supposed to switch between backup battery and normal battery. Too bad sometimes it does not do this at all...
finally this happened to me to today. I by mistake took the battery out and when I put it there again, it hard resetted itself. Many of my notes were stored in main memory, which I had taken from my teacher just 30 mins ago

It happened to me again few days ago, under 2003SE (I had to downgrade for something). One thing i love in WM5 that I don't have to worry about this.
It has happened to me many times as well as I am always changing batteries. As somone mentioned above it seems to be a bug with the battery holder (the little black tab you clisk to hold the battery in.) I just keep my contacts backed up each time I add a new one. as for the applications they can usually waite till I restore them.

Eeerrrr. how about ' replace the battery' - they are standard cells...
Richard
Mabey its not clear what seems to be happening here
When you drop the unit and /or when you open the little black clip that holds the battery in place. Somtimes the phone looses all stored information and goes to hard reset. There seems to be 2 bugs in action here.
1) The batterys seem to get into a strange state where they dont work properly. (I have found that putting the battery into the rear slot of the charger reconditions it to fix this problem.)
2) Some units seem to have a bug with the battery latch when you open the latch accidently or somtimes even just when changing the battery intentionaly it seems not to switch to back up battery corectly. My theory is that there is a dead zone in the latch that does not make the correct transfer if it isn't fully engaged in either direction. It is a really poorly devised way to handle battery changes but hey its too late for them to redesign it. I can not say how many ppl have this issue or if it is everyone or just some people but I do know this is the case on mines and many of the forums I've read.
Solutions:
1) Back up your unit whenever you add data to it. you can just do a contact list back up which only takes 1 min for me and my sx66 has over 2k contacts. Do full back up once a week that should cover your apps and data.
2) Keep your battery reconditioned at least once a week use the rear charging slot for the battery. If you only have one battery this is not an option so I suggeest if you are going to keep your sx66 for any length of time buy a spare battery.
3) Recently I have begun using a small peice of duck tape to secure my battery latch. It is a pain in the rear but I have droped my unit once in this configuration and the battery and latch stayed in place.
Additionaly:
To make restores easier you can include some of your favorite applications in your ext roms. Just snoop around in the forums and you will see directions for manipulating ext rom.
Also look into changing the directorys where you store information. IE your mem card and the onboard storage directory seem to never get nuked unless it is done by the user.
Anything short of the above listed or replacing the hardware is not viable, because these are HARDWARE bugs. Version 5 avoids this issue because it does not hard reset your data like all previous versions of ppc. However the hard ware issue is still there it just doesnt effect you. But if you upgrade your rom be carefull because you are trading the bugs you know for the ones you don't know...lol
thanks for advice ........
dont worry richard am shifting to o2 exec

Hi all
I have a problem with my blue angel - when i disconnect the main battery (even for 1 second) it hard resets. It's strange because in the settings->Power the backup battery shows as fully charged.
So what should i do? Is it a faulty backup battery or what? And if it is how can I replace it?
Thanks for your answers!
I'm having exactly the same problem and getting sick of my blue angel, i use it for my sat nav and it's annoying to lose all s/w and settings
can anyone help??

Two options
1. Upgrare to w5 or w6 to advoid data lost when battery got trouble.
2. Use backup, such as spb back up and shceduled (everyday) backup, then you never lost your data and sw
Yes it is possible to replace backup battery as I had to change mine from my old broken xda iis < it was a little tricky job to remove the cap which holds the battery in its place securely, once you release the cap change the battery ( make sure you insert the new battery with correct polarity) and re insert the cap .
Takes 10 minutes thats only if you can release the cap without damaging any bits on the board. Just take your time dureing this process.

You forgot to mention.... Make sure to replace with proper "Rechargeable" Battery.
Where is the backup battery located on an SX66 BA? Where can one get one without spending a lot?
Thanks in advance.
Backup Battery
OK. I finally found some pictures of the HTC Blue Angel completely disassembled. Go here:
http://www.land-of-kain.de/ppc/mda3/disassembly/
It shows something that looks like a battery with a piece of silver tape. I assume this is the backup battery.
I am running a fantastic version of WM6.1 that is extremely stable and fast.
I've increased the memory available to 60MB (see the BA Wiki's upgrading to WM5 instructions). While WM6.1 does store your contacts and other info in non-volatile memory (i.e., it won't be erased if you battery goes dead), there are some passwords for internet settings, etc. that are not saved. So if my battery falls off (mine always does), I often have to add the password to connect to my carrier and I have to re-enter my password for the my push email. I believe I would not have to enter either if the backup battery was working. So I'm trying to figure out how to do it.
I found some of the backup batteries for $5.00 but one has to make a $35 minimum purchase. I'm still probably going to do it.
you can buy them from most shops - just make sure you buy the right type -
it would be this: http://www.onlybatteries.com/webimages/images/15293.jpg

I've opened my i-Mate PDA2K and the battery turns out to be an LR55 (aka AG8), judging by the dimensions (11x2mm).
The trickiest part about getting access to the battery was the battery cap. It twists in place but that doesn't do anything. I had to pry it open using a small knife as a lever against the component to the right of the, but that seems to have unglued the whole battery+cap ensemble from the PCB. I have no idea if the device will still work after I replace the battery.

Looking at your photos it seems you have took aout all the pieces.
If you see this http://forum.xda-developers.com/showthread.php?t=501989&page=11 you'll realize there are two pieces: the cap with three labels and the "small saucepan" where the batt properly is. And that should remain attached (soldered) at the mainboard. So, perhaps you have unsoldered something you shouldn't.
And the battery is the V18HRT, also known as V20HR ("V" because is Varta company). I bought one through ebay.
Good luck
Sigh. This is also my problem as my old Xda2s and HP iPaq both require internal battery replacement - Varta V18HRT. Is there a substitute for this considering its quite hard to find this Varta battery? And if one knows, where does one find this Varta battery in Manila.

I know this is an OLD thread, but I thought I would post regardless.
There is a suitable and AVAILABLE Varta NiMH button cell for our HTC Blue Angel smartphones. The Varta V20HR is a slightly higher capacity battery (20ma vs 18ma), same diameter and only super slightly thinner (2.25mm vs 2.3mm). The small difference in height should NOT make a difference as the backup battery cell holder is a spring tension design. I have order a couple of these (under $5 each) and will be undertaking the replacement once my order arrives.
Wow
I have found out that looks like the MBU20 also replaces the V20HR so it can be another option. I am going to try that one as I am in Europe and it seems all the V20HR available are in the US. It has a Nominal capacity of 20 mAh.
Here is a link for the MBU20 saying it replaces the V20HR: http://www.master-instruments.com.au/products/59150/MBU20.html
It has same measurements as the original V18HRT as you can see in the datasheet from Varta: http://www.varta-microbattery.com/applications/mb_data/documents/data_sheets/DS55802.pdf
And those MBU20 are quite cheap in Europe. I will post here an update. I still have my original Blue Angel going strong and 5 more as backups that I am working on making them nice again. I am glad I took them out of the drawer
