Hi, I have recently acquired (mid Sept. 2007) a TyTN II device: really a very good and nice device ... till yesterday.
Maybe my experience could be shared with some of you...
Yesterday my device suddenly turned off apparently because battery very low (i.e. less than 5% according to the manual): this is strange because as far as I remember my battery was charged enough to survive more than one day considering that I did not use Wifi/Bluetooth or many phone calls.
By the way, the problem occurred when I attempted to recharge the device: it spent hours under recharge but the power led never become green, but remained orange. I attempted anyway to startup the device, but as soon as the Windows OS started it automatically shutdown because battery too low was detected.
I performed several software reset and finally an hardware reset, while attempting also to recharge it also via USB but without any positive effect.
I contacted HTC which suggested me ... to provide back the device most likely for being replaced according to the DOA (Dead On Arrival) policy.
Please note that according to some tests I performed on the battery, this seems to be charged and the problem relying on the device or OS which do not recognize it as charged but so low that no operations are permitted.
Has some one experienced a similar issue with this new HTC device ?
Cheers,
Max
GF's 8125 did almost the same thing; wouldnt charge past 10% and kept sending notification after notification; this was literally right out of the box. Cingular/AT&T suspected the battery but replaced the 8125 as well.
So far I have not seen other reports of this for TyTn II. It is however a reasonably common problem with many different brands of phone.

Could be a Power managment issue its not uncommen at all. things go wrong in all electronic devices think of the millions of Kaisers that will be sold in the coming months a few are bound to messed up from the factory. Its like buying a car you know ****s guna happen but you buy it anyway since it looks really nice that first day!
Did you all charge using the supplied wallcharger instead of via USB?

Make your kaiser power off, and use wallcharger. If it still doesn't work, call for HTC..
Some problems are solved by letting the internal battery drain, by leaving the device without the battery for a couple of days.
That issue can happen if you (almost) run out of battery.
Best practice: NEVER EVER run down your battery below 5% ! As soon as it reach 10%, switch off if you dont have charger at that time.
You might go below 10%, but take the risk .... !
It is known to us that the new Windows Mobile 5.0 supports persistant memory (your data will not lost when the battery runs out 0%), but it does not say that you will not be able to charge the battery!
More explanation? And how to revive the battery?
Read this thread:
http://www.modaco.com/Warning-Battery-Chargin-t233233.html
It is well explained, how that happen and how to recover the battery

ey man, i followed the recommended procedure for the three firsts battery charges. First i plug the PDA and let charge at 100%, then i let the battery goes to 0% (yes, the PDA goes off, of course) and then plugin onto the wall charger, and let charge to the 100%, repeating this procedure three times.
I do this also with my previous PDA, Hermes. And no problem leting the PDA going to 0%...never see this problem before.
What is the supossed problem leting the battery goes to 0%?
Regards.
EDIT: Found this interesting information about LiIon... http://en.wikipedia.org/wiki/Lithium_ion_battery and http://www.batteryuniversity.com/parttwo-34.htm
jcespi2005,
I simply dont know I just shared the link that I knew from modaco which is useful in this case.
Maybe this is not 100% the case, but as I said "best practice" ... something that it is better to follow to avoid this issue as you should read already that quite a lot of people affected by this very low depleted battery.

The modaco thread talks about Wizard, i think it's not 100% the same as Kaiser, cause is not the same battery, and the hard charge interface on the PDA can be different. I'm going to make a deep research about model and manufacturer for the Kaiser Battery, to see what can be the issue.
Anyway, i let my Kaiser goes 0% three times and charge fine for the three times. So i beleave the issue is not related with the battery itself. Can be the charger? don't know...
What is the model and manufacturer for your Kaiser battery, please?
Mine is Samsung model KAIS160.
Just checked and I have the same battery, SAMSUNG KAIS160.
I have now seen another report on another forum with this problem (Kaiser). I suggested the standard method as used when the refusing to charge issue arose with the Hermes (TyTn).
(It worked by the way!)
i.e.
1
Remove the battery for half an hour or so
2
With the battery still removed connect and switch ON the official (1000mA) MAINS charger (Not other brands that deliver only 500mA)
3
Now insert the battery
4
Wait for up to 5 mins for the Red LED to change to Orange
Repeat steps 3 and 4 if you have no success after waiting for a reasonable time.
(If that fails then elsewhere I have reported the technique of delivering a charge to the battery using a couple of AA batteries)
My view for what it's worth:
Although in rare cases there may be a faulty battery, in the main the problem is not caused by the battery. The likely explanation is that the circuit that detects the battery's presence, fails to detect the battery when the battery charge is very low. In other words there is no problem with battery but the battery charge detection circuit is either frozen or does not switch on when the battery charge is too low.
This issue I see reported across many brands of phone and is not a WM specific problem.

Many thanks for the information, this confirms my suspects about the interface to the battery, and not the battery itself... i see this issue time ago with one Nokia 6100, and solve it with the same procedure you write. Sometimes LiIon battery gain some charge if you place in the refrigerator for a while (cool helps LiIon batterys, and warm hurts).
Regards.
EDIT: More info about charging LiIon battery here http://www.batteryuniversity.com/partone-12.htm
Seems there is no need to make three charge/discharge cycle before use the LiIon battery. Simply you can use and charge in any moment. Really is better sorts and many charges rather than less and longs charges/discharges.
Power Failure.
Hi guys,
Well the USB did the trick.
Don't forget the Red Wire is the + (Positive)
and
the black Wire is the - (Negative).
A few minutes holding in place did the trick.
Thanks a lot for this thread, I actually had the feeling that I have lost the Kaiser.

what USB trick? what wires, and where do you put them in the phone? thanks!
nevermind, just tried it and it definitely charged the phone, but when i then plugged it into the charger it the battery just decreased like before

Hello,
Take a USB cable (the one like you use to sync your pda) cut it in the middle, expose the wires inside.
The red wire (+) is to be attached to the PLUS of the battery, and the balck wire (-) is to be attached to the minus of the battery.
About one minute and fater re-install the battery and try charging again, this should do the trick.
You can also use 2 AA batteries in the same manner.
Yours,
Ronen
just happened to mine after only a month. Contacted att and the forum and had to get it replaced. So far nothing wrong with this one!

Hi Mike,
Had my Kaiser sent to a lab, they are checking it but they are saying it is a faulty board.
The battery is ok although I bought a new one and tested it to find still the same problem.
Thanks.
Hi everyone I`m new to this forum and new to all this stuff
So I hope I post this in right place,becouse I think it coul be solved with upgrading or so (is it really?)
So here is the fact:
I just got used qtek 9100.At beginning it didn`t charge at all.(but when I tested it it worked just fine,until the battery run out of juice)SO I charged it in other ways(my brother works with electronics so he just knew the way how to do it.)
And when I put it it my PDA it shows that it`s charging all the time....well some times-rare-it shows full battery.
And when I connect the real wall-charger-nothing happens
it don`t charge at all!even if the battery is fullcharged or compleatly empty.
So theres question-is it foult of hardware or can it be fixed with some soft?
Thanks for your help already
have a nice day.
.
Sorry for trouble,but i found the way-disabling the usb charging.
Sorry for trouble
No actually disabling usb charging didn`t resolve it.The battery isn`t charging at all!the only way is to take out the battery and charge it in other ways.
IS there any other ways?
I am a chinese, I am not good at english, but I hope can be help by you.
My phone I9000 ,ROM with JPY 2.2.1, when it is charge to 100%(indicated 100%）, i unplug it, then the battery displayed 97% or 99%,never be 100%. I am worried about it, what is the problem with my phone or rom or battery?
Charge 100%.... then turn off phone... wait until the phone is charged to 100% then switch back on.
crabby
In 2.2.1 firmwares, samsung made it so it stops charging at 95 to 98% charged, dont be alarmed
Sent from that Green Robot Device with a 4"screen, chewing on some froyo(with an extra .1)
Hundreds of posts on the subject search and you might find a fix .
jje
thanks
thanks for answer, so it is normal, i donn't need to fix it ,right?

That's right, it's a weird quirk.
Laptops do it all the time in order to increase battery life. Fully charging your battery can damage it.
when my phone is fully charged(I also got the notification)the battery's icon on the status-bar said 100%. But when I unplug the phone, the battery icon suddenly became 97%. I don't know what the hell happened to my battery. My phone couldn't charge over 97%. Does anyone can solve it? Please help me out!

This is a 'feature' of the i9000, it will rarely charge to an honest 100%.
There is also considerable debate around this issue or 'feature'.
I suggest you read threads like this one for more info; http://forum.xda-developers.com/showthread.php?t=871051
fear not, there is nothing wrong with your phone. If you like *THIS WILL DECREASE THE LIFE OF YOUR BATTERY* you can 'bump charge' it. This involves charging to 100%, turning it off, letting it charge to 100%, unplugging charger, replugging charger in, letting charger charge to 100%, repeat as much as you like. This process forces more juice in, but it can damage the longevity of your battery and possibly cause an overcharge if you do it too much.
You will find this mentioned in a lot of places, so please learn use the search tool. Apologies if you're getting started, but it is important to learn!
I will be getting my Xperia Z tomorrow, I've read somewhere that upon first use I have to charge the battery to 100% and then let it drop to ~5% and then to charge full again. This apparently extends battery life.
I just wanted to confirm whether or not this was correct or what would you recommend? Thanks :good:
This doesn't matter. The only thing Sony recommends you to do is charge the battery for 30 minutes before turning it on for the first time. Use it until the battery is dead, then charge to 100%, and then just use it as you normally would - no extra steps needed for Xperia's type of battery
If there is not a peice of paper in the box that tells you what you have to do on first use, eg charge for x hours... before you turn it on, would suggest that it is not a problem.
Pretty much what Akiainavas says if you are worried, would not hurt and I am sure would help prolong the life, although I would tend to charge for longer until it shows as fully charged, normally an LED colour change.
Thanks for your replies !
The staff will most likely power on the phone in the store tomorrow to set it up.
After that, I'll power it down and when I get back home I'll follow Akiainavas method
