It will charge via a usb port but only trickle or topup charge and only if your phone is not totally discharged as your mains chargers output is approx 7v and the usb port is approx 5v at least this is what i found out with my usb charger.

This is the CA-100 charger?

Nothing to do with voltage!
It's because USB port specs set a 500mA nominal rating and the Nokia mains charger is 800mA.
The lithium ion battery needs the extra ooomph to get them started from discharged state.
Some PC and laptop manufacturers do supply more from the USB port but it's the luck of the draw.
Simply answer is keep the battery on charge whenever possible. (USB, car, external power pack or mains).
Your battery will thank you for it!

Not Charging From Car Charger!

Hi All,

I can take this a step further I bought a Car Charger for my N95 and now find the phone says "Not Charging" Saddly I bought it from a shop that is to far away now to bother returning it.

But there does seem to be an issue with chargers?

Any advise?

Gerrit

You cannot charge your Nokia N95 through the mini USB port on the phone itself. You can use USB from your PC to the power adapter of the N95 to power the battery. Aftermarket chargers may not charge a battery from a dead state and they may not fully charge the battery to a full battery state. This is because of the mah ratings of the aftermarket chargers being 500mah and the Nokia needing 800mah to initiate charging on a drained battery.

Yes it has, and apparently people continue to still ask the same questions that keep getting the same answers. I now understand "the circle of life."

And sometimes people will take the information from multiple posts and summarize in one post to make it easier to find all the data needed for a specific outcome. Hence this post.

But what's the point of doing this in the same thread which supposedly all will have read by the time you post?
