Phone is too flat to charge My phone died today, and now it won't charge at all on the charger it came with. I don't think the battery has failed, as it still gives me just as much charge on a full charge as always. The phone is an LG P500 running CM7.

My battery charged perfectly in another model of the same phone. Does this suggest there is an actual problem with my phone?

What can I do to get my phone to start charging?
The phone should always charge, no matter how empty the battery is. You imply that the empty battery is the reason why it wouldn't charge, but I think that this is not true.

It is more likely that you are dealing with a hardware issue here. But first make sure that you connect the charger for at least an hour to your phone, just to make sure that it is really not charging. Even if there is no visual feedback of the charge process, there is still a chance that it does so. You could also try swapping the battery with the one from your brother, to see if the failure is the battery or with the phone.
