Time resets when removing main battery

[Guest ahell]

Hi,

I have a QTEK8310 and it has started reseting the clock every time I take out the battery (e.g. to swap memory card)

My first quess was that some sort of internal battery was broken and when I took it apart to clean from dust I had look but didn't see anything that looked like a battery.

Anyone that have an idea how to fix this? (except of handing it in for repair)

Thanks in advance

Anders

hey mine started doing that too it is a battery that has died I believe it is soldered to the circuit board.

I cant even return mine as it was a prize and I don't have a receipt

nor can I find any one who can repair it for me and I am not brave enough to have a go with out having read a guide as to how to do it.

[Guest ahell]

If anyone know where this battery is on the circuit board or atleast almost where. I think that I'm brave enough to try to swap it, I also believe that I have both the skills and the tools to do it ;) hopefully...

[Guest conan_troutman]

if you do do it please provide a guide with pics if possible so that others can attempt it too

Also the tyoe of battery needed and if poss where to get one

[Guest dm251x]

yes, please post any additional helpful info, because this is a pain.

Have you tried a full reset before you do all that? (the factory default one, two soft keys and power button).

My SP5m started doing this after the keypad became unresponsive and I had to remove the battery from it. It was a real pain as I was SIM swapping a lot at the time. I did a full reset and re-install and it's now fine again. Second time it's happened to me, I guess something in NVM got corrupted.

[Guest conan_troutman]

the ony reset i have tried is the clear storage one which I thought was the exact same as do ing the power on two soft button version

and still it does not fix thye time problem

I have tried different products that report memory and battery state and most report the back up battery as 100% but the odd one or two did show it at 0% so Iam st a loss

some peeps have even told me the back up battery is fictious and doesnot exist

but then ask so how does it keep tracking the time with no power?

Isnt this a born problem?

I got this problem since the first day already ;)

[Guest conan_troutman]

nope mine lasted 2 months till it died then it reverts to the 24 march 2006 every time I remove the battery so Presume that was when it was all put together which means the internal battery lasted all of 4 months top

[Guest slimgym]

Not sure what clear storage does, but to factory reset, power the phone off and wait till it's fully shut down. Hold the two soft keys in (either side of the home/back buttons) and press and release the power button. A menu will appear saying to press 0 to restore factory default, press 0 and it full resets. You will lose everything on the phone, texts, calendar, contacts, installed programs etc (obviously leaves the storage card alone so some progrmas can be brought back by re-creating shortcuts).

Hello

I have had this on my Orange C550 and C600 - I have noticed on mine this only occurs if you remove the battery without switching the phone off - if you switch off first and then remove the battery, this doesn't occur!

[Guest conan_troutman]

switching the phone off first does not solve the problem on my Qtek 8310 besides never had to switch it off first during the first two months when it didn't do it.

would seem like a pointless exercise as most people remove the battery with out poering down only when the phone freezes.

I had this problem on my Qtek 8010 after one year and ten months. I claimed the phone in the service center and after few days I got it back with brand new motherboard.

[Guest greenwood]

Great... my Qtek 8310 forgets the date too. What do they make these batteries from?

[Guest Qlphn]

funny... i tought it is expected to work that way :)

Both my C600 are clearing date/time when battery is removed (even if 'removed' means 1/4 s...)

[Guest greenwood]

If the battery is unplugged for a very short time, the time stays on my phone.

[Guest conan_troutman]

try the same next month...mine lost the ability to retain the date and time slowly...its like the battery should charge but never does so the period with out them battery gets shorter and shoerter until it's non existent.

[Guest tobbbie]

I had this already with my SDA-Music (QTEK8100) and now as well with my O2 XDA phone (QTEK8300 in the QTEK8200 housing). I think that the SDA-Music did a save/restore of the time when switched off properly, but lost time when locked up and I had to remove the battery for reset.

Are there no hooks in the shutdown-process that would allow to save the time and retrieve it from there upon startup? This would at least only loose a few seconds/minutes and not reset the time to the ROM-Date. This is especially annoying since several tools are flushing their data in such case (GPRS Monitor, Battery Plugin).

the problem here is not whether the phone shuts down properly or not...the problem is you can not swap the SD card with out it reseting the date and time

wether you close down the phone correctly or not the phones loses the date and time and always returns to the same factory set date and time.

there is a small watch like battery in most smartphones that will keep the date and time while the main battery is removed(which it has to be in order to swap the SD card) this seems to have a half life of about 6 months...hence we are all past our gaurentee date and now have a phone that is not as good as it should be.

we just need to find what type of battery it is wher i can buy one from and how easy/hard it is to dis-assemble the phone to replace said battery.

then we is all rocking and a rolling once more.

also how would a save restore work with out it knowing how long you were switched off for or how long the battery was removed for...there is a flaw in your logic there I am affraid.

[Guest Paraklas]

mine started losing time/date after 1 year.

resets to 01/03/2004 every time battery is removed for more than 10".

[Guest sebbes]

after 1.5year too, My 8310 started to loose time when the battery is out...

I think the point is the small backup battery that you can see on the 4th picture at Disassembly tornado

Seems like it doesnt last very long, and how could a clock continue to run without power :)

I use SKTSync

It pulls the time from the internet

When you put the battery back in, fire up the WiFi run this program and the exact time is set

connecting to AS or booting up some GPS programs do the same, however....that does not solve the issue does it...after all it should not be doing this in the first place.
