Default Computer draining the battery while on USB??

Please Login to Remove!

I just experienced something weird. Last night when I went to bed I left my bold on the USB charger which was on my computer (mac) thinking it would charge till full. It was on 95% when I left it.
The computer was turned on as I was copying some files to a hard drive.

But when I just checked all of a sudden my entire battery is drained it seemed.. Has anyone experienced something like this? I now put it on the travelcharger into an electric plug and it is charging again, but I just don't understand why this happened. Any thoughts?

the only thing I can think is that it did not detect a voltage on the cable and was not charging at all and by morning our glorious battery hog did its toll on the battery.

Actually I am one of the few people (or so it seems) that have no issues with the battery life. Normally when it is at 95% when I go to bed it will be around 93% when I wake up, so not too bad. It certainly shouldn't be empty... Maybe it was just one of those famous once in a lifetime things.. I'll try it again when I have time to recharge it in the morning in case it is dead again...

Not sure if this is true for the Bold, but I do know from my own experience that the old 7230 could not charge from a PC's USB port unless some of the BlackBerry drivers were present on the PC (ie Desktop Manager installed). The PC chats constantly with the Blackberry until the battery is totally exausted...

Here is some interesting info on another thread. Not sure if it is somehow related to your issue.

Pearl / Mac : USB charging current not sufficient
