My lad (grrrrr) who never looks after anything, has managed to bork
his^h^h^h the nokia 9500 he was given for Xmas. It's gone flat, and the
charger jack plug feels very loose in the socket.

The charger charges another 9500 fine, so it's phone-side.

Presuming he's knackered the socket, has anyone any experience of
repairing ? Spare parts aside, is it possible to replace it ?

In his (slight) defence, it really is the crappiest of crappy designs.
I've lost count of how many Nokia charger plugs there have been over the
years. Thank god we're going micro-USB now. One charger for my phone, the
Mrs phone, plus my Kindle ....

Don't know the 9500 but Google for "replace screen nokia 9500" and you will
probably find some detailed instructions and pictures on how to dismantle
it.

If you can get the replacement connector, it looks straightforward

Is it the really microscopic power connector?
I had a few of these die, until I discovered what was going wrong.
I keep my phone in my pocket. Dust gets into the charging socket,
and when you plug in the charger, the dust gets push to the bottom
of the hole. Over time, this builds up, and then the plug doesn't
go in as far, and doesn't click home. Eventually, it won't make
good enough contact to even charge and/or the plug drops out.

Having discovered this is what was going wrong, it was an easy
matter to poke around the hole with a pin, and it was amazing
how much dust came out of such a tiny hole.

Before doing this, I had taken the phone to bits and cleaned up
the contacts on the charging block where they press on the circuit
board, thinking this was the problem, but it made no difference
of course. By searching on the web, I did find someone selling
the charging blocks, but I never got around to ordering a new one.
That would also have fixed my problem.

I had exactly the same problem. Ended up buying another phone.

If only that last were true. USB chargers are as variable as anything else.
The one that charges my headphones for example won't charge my GPS or
Kindle. The one that charges the GPS won't charge the Kindle. And so on.

Are they all microUSB though, or a mixture of USB, miniUSB and microUSB?

Well none of the micro-USBs I have will charge my PS3 controllers - but that
is rather a special case I suppose.

There's a relatively new standard for USB chargers, which involve
using resistors on the data lines to signal back to the appliance
that it's connected to a charger which can supply more current than
a regular USB interface can.

Hisory:

Originally, you could draw 100mA from a USB interface, unless the
peripheral negotiated with the host, in which case it could be
negotiated up to 500mA. This requires an intelligent controller
though, and chargers don't have any such intelligence built in.
Very few USB controllers actually police the current draw to
enforce what's been negotiated, although there have been some
which do. There are many peripherals/appliances which draw more
than is allowed, without negotiating this with the host.

Some manufacturers went for proprietry solutions, and one which
was used in some cases was to raise the voltage from 5.0V (with
a max permitted 5.25V in the USB standard) to 5.5V, which signals
to the appliance that it's plugged into a power supply rather
than a USB data port. However, this was never part of the
standard, and in theory, feeding 5.5V into some USB appliances
could damage them (being above the max allowed in the spec),
although very unlikely.

The EU pushed the mobile phone manufacturers for one type of
charger, and as a result of that, the ability to supply higher
current through a USB interface without negotiating it over the
data lines was added to the USB spec. It's done by having
resistors of specific values connected to the USB data lines
in the charger.

Of course, at the moment there are still plenty of USB
chargers and appliances which predate this new standard.

chargers and appliances which predate this new standard.

And by the time that the standard is being complied with by all the
equipment in use, there'll be a new standard which won't be compatible,
and so on for the foreseeable future.

They are all the same plug which I think is microusb. The problem is that
each has different current limiting.
