I used my Dell laptop to activate my iphone, and ever since then the battery on my laptop could only hold 30 minutes of battery (as compared to a 3 hour lifetime before). Has anyone else experienced this problem? Or is it unrelated?
I really doubt it ruined it or there would be MANY reports of this since there are a lot of laptop users out there.
However, if your iPhone is plugged into your Dell all the time and the Dell itself is not plugged in then you will see a huge drain even when the iPhone is fully charged. I try yo avoid running anything off USB while on battery, but then again I try to keep my PowerBook plugged in all the time too.
While I have no explaination for this, my MBP battery has suffered the same. The last two days, I've barely got an hour of use w/o the iPhone plugged in. Prior to having the iPhone and charging it through the USB ports on the MBP, I was getting over 3 hrs.
It doesn't make sense that the iPhone would cause this but I don't have another explanation at the moment.
