After the main battery drains out my Universal's clock and calendar loose synchronisation. I think it's backup battery issue. Am I right? If yes how to change that?
Uni has no backup battery, sorry.
Normally it shuts down just before the battery is drained, so it still has some power to keep it's clock running for a long time.
So, maybe your device refused to shut down in time.
Guess what? I am using Nokia's BL-5C 1050 mAh battery connected to two top and two bottom terminals of Universal so no one knows how much power is left in battery.
I guess it have
because last time when i change the battery, I don't have to set the time
but now it happend, i have to set the time when the battery drain or remove
Or because of the Rom???
I think, that Universal has a backup battery? Isn't it this small battery next to "turning-on" button on the Mainboard ?
Yes I think there must be some backup battery because if you even remove main battery the Universal retains time sync over a long period of time.
I thought that WM5 and onwards had to have persistant memory since previous CE editions lost everything when battery became discharged.
that is partly true. in wm2003se, the pim data and most of other storage based apps and data were stored in the ram, being the primary partition. all that was lost, if the device ran out of power for a too long time. however, it could persist a normal soft reset or battery change thanks to the backup battery. from wm5 onwards, there is no data stored in the ram, and that is why you don't actually loose data, even after taking out the battery forever. the storage used now is a persistent memory, meaning, like with a usb stick, the data is stored on a flash based chip, that can store files, independant of power supply, while the ramdisk or the wm2003 memory is on the ram, which needs power, not to loose the data.
so whatever the poster has on a potential ramdisk, as well as the clock, will be lost, whenever the power supply is cut. and since apparently that seems to happen directly after the battery is taken out, the backup battery is broken.
to provide the original poster with further information:
you can download the universal service manual here:
http://mikechannon.net/PDF Manuals/HTC Universal_Service-Manual.pdf
in there, you will find the exact instructions and spare parts you need to change the backup battery.
that should solve your initial problem.

Has anyone seen this: my battery was fully charged at the end of the afternoon, I made a few calls (not too long). The day after my machine did not react; after placing it in the cradle it finally came to life... EVERYTHING WAS GONE.
One would think that a daily sync would backup most stuff, but this has proven to me a major misjudgement of mine... My daily time4life reporting is gone. This sucks.
Anyone knows how to recover this? Why isn't the information safe on this machine?
Yep, get sprite back-up it has a battery monitor function.
Turn the Bluetooth and wifi off when you dont need them.
Save your work on the SD card

If you live in an area of poor network coverage, it is advisable to switch off the radio overnight. If the phone can't get a good sugnal it constantly polls looking for a better signal and draining the battery.
But we're living in de 21-th century... Surely some power can be held in reserve to save the memory...
It sucks bigtime!
But, I will look at sprite backup and will put My documents on the SD card.
Thanx for the tips
I had a similar issue but caught it in time...
I was using an MP3 player and had launched the camera function by accident. On taking the thing off my belt, it was HOT :shock: and had hardly any battery left.
I suppose from an 85% battery, using for 1 hour with the MP3 and camera app running had exhausted the battery. Very worrying, but more so was the XDAIIs was so hot - either the battery or the main unit - not sure.
Have used the MP3 on its own for several hours with no probs, so I can only surmise that the camera eats battery power....... so, could it have been that which was running on yours, hst?
Sorry complete newbie to the XDA IIs here after having ditched my Ipaq H6365. (I only had that for 7 days so not exactly a seasoned ppc user)
When you say you lose everything when you have a flat battery what does that mean? Is this the same as a hard reset? Installed programmes gone?
Is it all emails, text messages and contacts?
it is worrying if so as I travel a lot and sometimes might not get chance to charge my XDA and can do without losing these. is there a way to save your contacts etc to a storage card?
Thanks
For all the n00bs and people who don't know...
The XDAs have different types of memory. The Operating system is kept in "Non volatile" memory. This is safe, even without power.
Now, all the programs and your "Documents" that ARE NOT kept on a storage card and kept in the "volatile" memory. This needs constant power otherwise, it wipes it!!!! This is like doing a HARD RESET! Installed programs, e-mail, pictures, etc - GONE!!!!
As far as I'm aware there is NO WAY to recover from volatile memory that has lost it's power.
Regards,
Dom
PS: If any of this is wrong - feel free to correct me!
Well I found out that everything is gone. Still a simple user like me expects all memory to be non-volatile... or at least that when the battery is low, the system will hibernate or something, until it has enough power to operate again. I don't care about e-mail and other recoverable stuff, but I do care about the recording of my billing hours which kept in de database folder!
Bugger.
I am a new BA user. I noticed that to change the SIM card the BA restart " as new" and all data is lost. Is there anyway to change SIM card keeping my data?
Thank you all
Hi
Although I've never done that before (and now you scared me to try it )
I think it's not true.
In order to change SIM, you had to remove main battery. Notice that in this case, the internal backup battery will stand only for few minutes, keeping RAM alive.
Maybe you just weren't fast enough, changing your SIM.
Another thing. When you put main battery back, BA won't use it until you power it on. So putting main battery back, but not waking BA will cause data loss in few minutes.
Maybe i'm wrong.. Maybe I'll play with it later.
Good luck
The only secure way to change SIM is making this with BA conneted to the main power. I try a few times and in all I had my BA hard-Reseted.
Be careful!!

I try on my BA to change the SIM card many times.. and no problem so far the backup batrery is fully charged !!!
Hi again...
I've checked it also.. No data loss..
Dcoelho if you always get data loss when changing sim, it maybe the problem of faulty backup battery (indra9110 suggestion).
Here's what you shold do:
Remove main battery but don't change the SIM !
Just wait minute or so (same amount of time you used when you changed SIMs)
And then replace the battery and see.
If you loose data, it will be obvious that not changing SIM, but only removing battery gets you data loss.
See Settings->System->Power Backup battery power bar.
Maybe it doesn't get charged properly.
Or maybe it says it's charged but it's not (I've seen such case on HP H5550).
Check the thing and report
I have done it many time, iv also dropped the BA the battery has come off, just plug it back in, i find that it only softresests when i remove.
I supose this works similar for Blue Angel as for Himalaya.
Just turn off radio (go into flight mode) before changing sims will avoid your device to hard-reset.
Hello EveryOne,
I have Imate PDA2K and any one who is going to solve my following two issues i will pay him $5 as a gift from me by PayPal.
The problems are:
1. When ever i remove the battery of my phone to change the sim card the time and date changes to the default time and date something like the manufature date. I try to upgrade the rom to wm5, then wm6 but nothing help. Even the backup battery is showing 100% full all the time.
2. When ever i try to call i press the answer button but the call don't connects. Some times connects and some time i have to try hundreds of time to connect my call. Same thing is for the recieving the call. Some time it connects and sometimes it hangs during answering the call.
I will really pay $5 who will help me to sort out these problems. I buy this device as pre-owned device that's why not able to get help at clubimate.com and hence plan to get help here and pay a part of pre-owned fee to someone here.
Thank you,
1.) it's a backup battery problem, change the backup battery.
eventhough it says 100% doesnt mean it's not failing.
the backup battery is charging from your main battery.
it may show 100% but easy recharged when you put the main battery.
if it is easily recharged... it will easily discharge... hence, flat batt.
2.) i dont know this but it maybe related to main battery failing to give power to the phone module. i had a BA with no service /and/ talks disconnection once but when i changed to a new battery it was gone.

Thanx for your response...
1. Can backup battery easily changable i mean is it like a big battery like we have in our pc motherboards or a special service center have to change it?
2. Let me change the baterry today and see what happens.
no prob... just add your reward to your battery procurement.
and i hope that works...
What else may be?

I have changed the battery today and it done the same call answering problem just one time in over 20 calls before this ratio was 99% of 100% times.
What else may be creating this problem of hanging mobile during recieving the call. And also please tell me which rom of wm6 is best you think i will use?
install 2003se rom back, if u hv 2005.
try xplode's latest cook. it's in the WM6 thread of BA
The rom does not matter (well mine is a lil quicker than others but)
1. Simple SIM change procedure - press power, wait 10-20 sec. , then remove the battery and change the sim. after powering on hit reset once (or you will get no radio) - this way the date will not reset
2. Phone LAG - this problem occures when a lot of memory and cpu power is used for the OS, then the phone starts to lag. Here is a simple tweak which will speed up the phone app - press Start => Settings => Sounds & Notifications , remove the check for Events (warnings, system events)
there are a lot of tweaks which will speed up overall performance of the phone, but you need to search the forums for them
And remember, the phone app is the same for all WM5/6 devices so the tweaks are the same, you can look in other devices forums for tweaks
Thnx Every One!
Hello,
Thank you every one for your replies.
I changed the battery and currently checking it to make sure the problems got solve out.
Using my phone I have tried different methods of installing the latest VanijEclair on my Tilt. However ever since I installed everything on Nand including data I have noticed that I have awsome battery life on a fresh install. I am using 2G all the time also but even with 3G on I get a little better battery life when installed strickly on Nand.
Before I settled on this method I tried installing Sys on Nand and Data on SD and I would go to work have to recharge at the end of the day because my phone would just die. The only thing that I can think of is that even when the phone is off the sdcard is constantly reading and writing data sucking down precious battery power throught the day.
Although when installing strictly on Nand you don't receive the benefits of more space you do gain speed I think as my phone is pretty smooth so far.
Has anyone experienced this?
My view is this, when we flash the NBH, it creates 4 partitions in nand, one for boot, one for system, one for data, and one for cache, ( I think that's correct, please let me know if I'm wrong), anyway, if we install sys on nand, data on SD, what happens to the /data partition on nand? Is it magically transformed into RAM or something else? No, it just sits there doing nothing, you could hack the partition sizes to free up more space on system, by 'stealing' it from the redundant /data partition, but that has no real benefit either, apart from being able to install huge experimental builds, like a hero/sense one I'm playing with, ( no it won't boot, and it's so old it has cobwebs on /system/media).
So why waste that space, I've always used sys and data on nand, and tried to control my bad habit of downloading every damn widget and app i like, because I'm really only going to use once, or maybe twice, and battery life is something that 'improves' with use anyway, ( it's called battery calibration, the longer you use a build, the better the battery calibration gets).
I do think that the ideal set up would be similar to the one I use on my G1, sys and data on nand, ( naturally), sd card partitioned 64,512 swap/ext2, the remaining space fat32, use apps2sd and either swapper2 or enable swap from spare parts, (some builds have that option, unsure if it works on kais tho, something else to play with if I get the time).
The reason why battery life is worse using SD may be that is just less efficient anyway, it's certainly slower, and ties you to that SD card, which is usually fine, but occasionally like to transfer data, and removing the SD is possible if it does not contain part of the OS
Hello.
I've just installed android on my HTC Tytn II (Not so Super Froyo Release).
It is very nice but the battery life is very short. I don't think that i can manage for one day without recharging. I think a couple of hours just. Is there something i can do to improve this? When i entered the #*#*4636*#*# it says that the android system is the one that keeps the processor running when in stand by. what can i do?
And another question. How is it better to install. On nand system and data? For now, i've installed data on external data.img. But there is not much room for aplications. Is it better if i install data on sd partition? And if so....how do i do that?

If the processor is still running while in standby then that means you have a widget or program running that's preventing the phone from going to sleep. When you install an app in Android always look for "Prevents Phone from Sleeping" where the app installer says what the app requires to access.
Also, as I have said in the help thread, there is nothing you can do about the battery life. It's Kernel related and being investigated, so until that time unfortunately battery life is very short because the phone's CPU while not in standby runs at 100% speed, unlike all other android phones which decrease their CPU speed and voltage when they are idle (sitting at the home screen or even checking emails).
Also, if you are installing into a data.img file on your SD Card, you should have about 256MB of usable space in /data, if you are running out of space with just a few applications, then you are still installing on NAND, as it only has about 90-100MB available depending on how you have your NAND partitioned, please verify that you have fstab set correctly in atools and re-flash your firmware so that it reads the /data partition under data.img instead of NAND p3.
BEst thing to do if you are wanting to install /data on SD Card (or data.img), is have /system on your NAND for best performance when Android is loading from boot. For quick performance, you should have /data and /system on NAND. For more space and stability, go with /system on NAND and /data on either SD Card partition or data.img.
Thank you for the answer.
I have another problem...when i'm recharging the phone...it says that it is fully charged at 90%.

That means there is a incorrect battery calibration number in the kernel. Run atools and check under Battery Settings > Advanced Settings. If you have a 1350mAH battery (noted on the battery itself), input 2160 units.
If you have any other type of battery, take that battery's mAH and multiply it by 1.6 to get the battery units. If the battery continues to stop at 90% after making that change, and the battery is old, then the battery may be losing it's charge and can only sustain up to 90% of it's core charge.
Thank you. now i'm trying with 2160 set in atools. i will inform you if something is wrong
Another question. How can i see the battery status in %?
i think now it's ok. but still the battery life is very short. and somethig is keeping the android from sleeping but i don't know what. when i enter in the *#*#4636#*#* it says that the "android system" is the one that prevents from sleeping.
And another question. What is the difference between panels. If i am installing with panel 1 the screen looks very bad. Now i've installed with panel 3 but i don't see any difference from panel 2. It is ok that i've installed with panel 3 or should i use panel 2?
I need to know how you set your phone up, including kernel, system/data partitions, which build you used, what radio you're using, anything that could help me investigate further.
I have 2 AT&T Tilt phones, one for daily use and the other for testing purposes only. (nice to have friends with connections, I got them both for free).
My current "daily use" phone will use about 1/2 battery per day with moderate use (texting/Pandora/phone calls) and will last 3 1/2 days if I just let it sit in standby. 3G is enabled and I use Rogue Tools to O/C to 480. I get almost no FC errors and everything works as it should. (The only FC I get is with ADW, which I press "wait" and it comes right back). I was able to set up my phone on the wireless domain at work and ported my work email to it.
Again, I would need to know what you're running as it sounds like your phone is not actually "sleeping" when it should.

So...the radio is 1.70.09.1 or something like that, the latest 2.6.32 kernel. android build is valentine. I am using system on NAND and data on data.img. now i can use the phone for a full day of use but i have other problems. when i charge the phone it freeze and white screen appears. Usually i left for charge at night so in the morning i find it with white screen.
Can u please tell me what are you using so i can use to?
Thank you in advance
