Battery Backup? - JASJAR, XDA Exec, MDA Pro General

On my PDA2k, when I looked at the battery display, it showed me the main battery and the backup battery.
On my M5000, I only see the main battery...? Does it have a backup battery? Am I safe to get the SIM out without it all resetting?
I'm guessing it is, but would like to be sure

The Universal uses persistent memory. Your data is safe if the battery runs down. Just like a mobile phone, when you change the battery etc you don't lose your phone back! Its taken M$ and HTC years to get this basic tech to market!

Backup Battery problem

My XDAII backup battery shows 100% all the time but if I remove the main battery even for 5 seconds I lose everything. When I power it back up the backup battery still shows 100%. would this be a fault with the batter or the pda?
I have sprite backup software but I am unsure if it backs everything up properly as last time I used it to restore, something was corrupted and I could send sms messages but was unable to receive them. So I had to take the battery out and then tediously load all of my apps again and forget about restoring from a backup.
Any ideas???
I do have the same problem and the phone resets on 25% main battery
any help?
Change you back up battery
hey guys you just need to change your Back up battery. There is a small battery inside our phone. search for battery change manual (or a PDF) available online. Please take a back up of data or you may loose everything.
check your manual and bring the same make battery before you open the phone.

noob backup battery Q...?

when is th Backup battery used and for what?
thanks
the magician (and many others older model) doesn't have persistent memory, it needs a battery to keep its contents. The backup battery will not start your phone, but it will keep your data safe for a few days (after your main battery goes dead), giving you enough time to charge your battery.
Super!
thanks for the info!
Cheers,
Klenovsky

Have you tried how long the backup battery lasts? Because once my main battery exhausted, and after 30 minutes I put on the charger, and saw the backup battery is at 80 %... So I think the backup battery lasts for a half day, or is it depends on what background porgrams running, or what?

Jam and all other wm2003 device have two type of backup battary option....
1)Which is situated in jam motherboard...a 3v battery...
if u remove ur man battery then it will keep power on ram for 30-40 min at most....after that a hard reset...
2)jam keep a portion of main battery for backup reason...that is if even ur main battery reach 0%...then this backup portion of main battery will keep power to ram for nearly 72hours (3Days)...if ths portion also reach to 0% then the 1st option will work for 40 min..
i think this will clear any quary abt backup battery of wm2003 device..
PS:new wm5 devices doesnt have any backup batter nor the 1st one nor do the 2nd one...as this is a persistent memory based os...thats is one another reson thats why wm5 devices have better battery performance then of wm2003..

Anyone changed the internal battery?

I am having problems with the internal battery in my wizard. Everytime I switch battery my clock and calender resets. I have the service manual and see where the back-up battery is. I was just wondering what kind of battery it is and if I can just replace it?

The Wizard does not have a backup battery like other PDA's. It has a persistant memory model like a PC. I have never had to remove the battery so I guess the clock would reset.
Whether the Wizard has a battery or not there is definitely a design flaw. It always used to remember the time and date settings when removing the main battery buy after about 6 months it no longer does. this has happen on both our Wizards and many others. It's very annoying when you change sims and then have to reset the time and date.
So far nobody has been able to explain why this is happening. There are thoughts that it may be the new roms which have changed something in the power management.
Kiru, you say you have the service manual and have found / identified the backup battery? That would very interesting if there is one.
I remove my battery to move my sim to other phones quite regularly, and my clock/date settings always remain intact on my mini-s. If I look at battery stats on my SPB pocket plus, it shows 2 batterys. Main batt and backup batt. I always assumed the device had a backup battery to store date/time settings.....

The wizard does have a back up battery. If you look in the service manual it shows where it is. My wizard used to hold the time and date when changing battery....just lately is hasn't been doing it......just want to know what kind of battery it has so I can see if I can change it myself...
here is the manul for anyone that wants it....I remember it was posted here b4....

He's talking about the small backup battery inside the device. If your sure Wizard has a backup battey, then yes its removable.
The type of battery, and volt is labeled on either side of the battery.
Just my $.02...
If this problem is less than a year old try warranty repair options?
Also, you can set the phone to update its time and date from the cell tower. I've never set the clock on my device it just nabs that information from the cell tower. Should happen as soon as you get a signal instantly...
The setting for it is under Phone -> Time Zones
Hope those help...
As i'm sure the backup battery is only used for the RTC (Real Time Clock) since the device is now persistent storage...

I clicked on this link and it showed me a file name Wizard_Service_Manual.pdf, but no way to download it!
To download from that site, you have to type in the security key shown on that page. Then a time will begin and after 60 seconds, you'll be allowed to download the file by right clicking and selecting 'save as...'

Just follow what FESCSteve said...and it should work....if not....then send me a pm and I can email it out to you
When i switched my mainboard my back up battery was dead, but after a couple days its back to normal, so i guess just keep charging your device and the back up battery will work again.
as for replacing it, it's soldered on so you'll have to unsolder it to replace it.
At page 37 of the service manual you can see about a "Golden Cap". It is not a battery, it is an high capacity capacitor. It works like a battery but has never to be replaced because it (should be) is charged by internal circuitry from main battery.

okay I managed to get my internal battery working once again!!!.....I think is drained due to the fact that I don't charge my batteries with my phone, but use a desktop charger. I then plugged my phone into the charger for about 24 hours, and finally, the back battery is charging (as to what pocket breeze says) It still isn't 100% charged, but it seems to be holding the time and date again!!!... just fyi I have 3 batteries for my wizard and never charge them using the phone....so that could have been my problem.
same problem here

Last week my battery was totally empty so I had to charge it using my 220V charger.. At that time I also found out that my internal battery is empty when I exchange SIM cards. Last Sunday I charged my SPV M3000 for like15-20 hours but I still have the same problem...
What more can I do to make it work again?
I have same problem with my O2 Mini S. I charged it with the wall charger for around 18 hours although it took just 2 hours to get the the main battery fully charged. The date/time still reset when I plugged it out and removed the main battery.
Anybody kindly help please. Thanks so much in advance.
too bad my problem came back again....and I don't know why.....when I left my phone charging almost all day, my battery meter says my backup battery is 75% full.....then when i changed my battery.....all my clocks reset again...it's gets really annyoing especially if you change batteries alot. But does this only happen when people are using spare batteries?..and always swapping back and fourth?, I rarely use the phone to charge my battery as i have a desktop charger.

It seems that there really is a backup battery (capacitor) that can be damaged. I have read the Wizard service manual and this little component has to be replaced if this problem still occurs :-(....
both mine and my wife's wizards are only charged by the mains charger and they both loose the time and date settings when changing sims. This problem started about 6 months after having the phones so I think some component seems to fail after a while as there are many reports of this happening.
All I can say is that it's very annoying as I travel frequently and change sims often.
As for getting the time from the cell tower, this doesn't work for me for some reason.

Unfortunatly I have the same problem. When changing the sim and thus removing the battery I lose the time and date setting. I charge my phone by the mains charger or sometimes by an USB port.
Perhaps it has to do with the new ROM I use? I recently upgraded to the molski rom. Perfect ROM by the way.

I don't think it's the ROMs. I still use the original WWE I-Mate rom (2.16, the one and only update they did so far). It's possible that the ROM introduced the problem but then everyone using the ROM would have the problem which is not the case I believe.

does backup battery is useful?

we know that backup battery is important in wm2003, but does it still useful when we're in wm06? since the memory still be saved in the main memory..
just a thought= is there any tweak or registry input which read both battery (main and backup) as one unity (a big battery) so after the main battery drains, device will automatically change to backup battery...
regards
adri
The backup battery does not hold enough power to drive the full PDa..it would not last long at all...it is only used to keep the memory data intact.
Works without the backup battery..
I ran my BA for a while without the backup battery. The only thing that happened was that the clock resetted itself on reboot...

Battery dies very fast, how to monitor tasks better?

My battery on the HTC Pure went from 45% charge to 2% auto-shutoff within a matter of 1.5 hours without any usage on my part. In fact, I had rebooted it and not touched it since.
The thing has been dying a lot faster after I installed some programs from Marketplace. I'm wondering if they are doing background processes that zap its power or what.
Any recommendations on monitoring what's going on in the background???
try to calibrate battery
(thanks helgee):
1. Discharge the device. Absolutely.
2. Take out battery for 60 sec.
3. Put the battery back. Don't switch on the device!
4. Charge the device by normal way (not by usb!) to the full state (green LED).
5. Take out battery again for 60 sec.
6. Put the battery back.
7. Switch on the device.
How can you discharged your battery? I didn't find a option on my Touch Diamond 2.

You don't do this unless you want to damage the battery.

Exactly the same thing here, after installing some apps from Marketplace, the batt started to drain very fast. Don't know why yet. The apps installed are:
Mobeedo
Bing
Pocketnow
The Daily News
I've removed Mobeedo, The Daily News and Pocketnow just to test if they were doing something.

Fast battery discharge
I had this very same problem. I had it with WM 6.1 and the Pure. Both due to the same app. BING is your problem. If you have a memory card in your phone it causes it to be constantly accessed instead of just on demand such as with storing pictures from camera. This is a battery life killer. Ditch BING, remove your storage card, save what you want to a PC and wipe it. After that put your saved files back on the card and put back in phone. This should stop the battery drain issue. Hope this helps.
ALSO: Some people swear by the battery drain and charge thing...others do not. Use it if you like but without getting rid of BING or finding a way to keep it from accessing your memory card the difference you will see will be barely noticeable.
Radio!~
u can change the radio , then u will get better.
