battery recharging and monitoring

Recharging my n93 through an usb 2.0 cable plugged in my laptop seems
to take forevere. After 48 hours it was still charging, Is there
something wrong?
I would like to find an utility to monitor the batery level. Any
suggestiobs?
By the way, will the S60 be upgradable to 3.1, some day?

Thank you

A Laptop USB port cannot provide the kind of current that phone's charger
is capable of producing. So, for the few milliamps the USB port on the
laptop can produce, it takes much longer to recharge it, ESPECIALLY if
the charger must also keep up with the phone pulling nearly as much
current as is available in th efirst place. It might never recharge the
phone.

Get a real USB chaarger for it....

Hi Pol,

I have a Nokia N95 and I never use the mains charger to charge it.

I purchased the Nokia CA-100 USB charger, which is the official USB
charger (NOT the standard USB cable supplied with the phone) but I
also admit I charge it from my desktop, rather than my laptop,
although I can't really see that it would make any difference with the
adaptor.

I agree with Larry to some extent though, that is does take a LITTLE
longer, but not as much time as you seem to suggest, but maybe if the
phone is down to the last 'bar' on the battery indicator, it may take
1.5 hours !
I also have a Nokia 6288 as a spare and my wife has a Nokia 6280 and
they also chatge fine with this adaptor !

I have looked on the Nokia (UK) website and it shows that the adaptor
is compatible with the N93 :-
http://www.nokia.co.uk/A4808753

And here is the actual adaptor itself :
http://www.nokia.co.uk/A4808752

Anyway, I have been using nothing else but this adaptor to charge the
3 phones from the USB port for exactly a year now with no problems !

I am not sure if you are in the UK or USA etc. but the adaptor cost me
£14 (UK) a year ago !

Hope this helps.

Battery indicator shows all bars, so my guess is that charging has
almost stopped at, say, 80-90 per cent.
As far as i can tell, no phone functions were on, during the recharging,

Thankk you

as provided already above ,
an standard USB Port cannot provide the amount of power needed
to recharge an Phone or any other device.
there is difference between USB 2.0 and USB 1.0
also between laptops and Desktops concerning the amount of mA which can
given from USB Port to connected DEvices.
There are few laptops / Toshiba / Asus ... (just google)
which have One USB Port who is capable of charging devices even
when Laptop is off.

Coming back to difference btn. USB 2.0 and 1.0
as far as i am concerned my opinion is that the amount of power provided
by usb 2.0 is ten times larger than the amount of usb 1.0 port.
(just google to check).

Hi again Pol,

I have just had an afterthought .....
My Nokia N95, 6280, 6288 and even my old 6230i NEVER charge through
the USB cable !!!!
You have to either use the supplied Mains Charger, or use the Nokia
CA-100 that I described in great detail in my last reply !!!!!!

No wonder the battery didn't charge by usung the USB cable !
I should have spotted this straight away ... sorry !

So to recap ....
YOU MUST EITHER USE THE SUPPLIED NOKIA MAINS CHARGER....
OR....
PURCHASE THE NOKIA CA-100 IF YOU WANT TO CHARGE THE PHONE VIA A USB
PORT !

Also as far as I know (and i have looked at LOTS of utilities) ther is
no barttery monitoring software for the N93 ... unless someone here
knows different !

The laptops have current limiters in them to prevent users from prematurely
killing the already-overloaded battery packs. Desktops, being nuclear
powered, have plenty of watts to charge batteries.

But, all that said, I still can't imagine why anyone would jeopardize a
thousand dollar computer system just to charge his phone. Suppose
something happens to the battery pack or charging system inside the phone
while it's attached to the expensive computer? Will the USB on the
MOTHERBOARD survive the short? Will the MOTHERBOARD have cooked traces
INSIDE its multilayered printed circuit?

If you trash a charger shorting its output, you're out 10 quid, not 500!

The MOTHERBOARD designers never intended you to charge your phone from
their expensive MOTHERBOARD. Is braggin' rights that important to take
that chance?

I don't think so.....

I see your point.
I use to work with a usb backlit keyboard, Is my motherboard at risk?

Thank you

You mean the battery can never be FULLY charged?

Thank you

Hi Larry,

Yes, you are coorect about mA limiters etc, hence the reason some USB
hubs come with separate power supplies to power them !

Your point about the battery pack (and this is one of the reasons I
ONLY use genuine Nokia batteries !) etc and damaging the motherboard,
has already been taken into account by Nokia ... they don't want to be
sued for motherboard damage cuased by their USB chargers !
Nokia have thought about your point and fully addressed it !

If you look at their adaptor, the CA-100, (see my previous message for
the link to the site for a piccy !) the USB part has a
regulator/current protection circuit in it ... this actually gets warm
in use, then cools when battery is fully charged !
So, sorry to inform you that if you use the correct Nokia USB charger
your motherboard is at NO RISK !!!!
As I said before, I have used it every day for over a year, and charge
3 phones with it and have no worries about damaging my VERY expensive
computer !

It has NOTHING to do with "braggin' rights", I don't know why you
suggest this, I find it quite offensive that you suggest this.
It is just convienient to charge by USB for me, as I am disabled and
my mobile phone sits next to me all day at my computer in case of
emergencies or difficulties I might get into, this way it is always
charged up !
I have no easily accessible mains sockets in my computer room, and
even if I did, access to them for me would be difficult because of my
disability !

Your point was a valid one ... but as I say totally sorted by Nokia !
But please DO look at the pic of the adaptor, and even feel free to
contact Nokia too to verify what I say !

Kindest Regards,
Steve

No, it doesn't have a high tech battery with a perpensity to explode.

Regardless of where they choose to have their products made, Nokia
still have the opportunity to specify the assembly process and manage
the quality control. If they fail to do so and end up with an inferior
product, that's their mistake and they'll suffer the consequences of a
bad reputation.
