I have had two iphones in two weeks and I have noticed that the charge i get from the wall seems to last alot longer than the charge from the USB port.

I thought that my 1st phone had a defective battery and I exchanged it but now the new phone does the exact same thing, so I'm thinking its because I keep my phone plugged into my PC at work allday while listening to internet radio?

Has anyone else noticed this or am i over analysing this :confused:
 
Can someone give me the name of a good reliable car charger? I have bought some in the past for my blackberry and ended up with lemoms.
 
I wonder why this could be?

Maybe because the USB charge doesn't actually fully charge the iPhone, but the wall does. Keep an eye on that wall charger though... you may burn your house down. ;)

I thought it wasen't at difference, the wallcharger is just a converter? It's the same cable carrying electricity. I could be wrong though.

remember that the original 3G wall plugs were recalled because they were catching on fire?
 
i have noticed that my wall charger seems to keep the iphone charged longer. also i have the 1st gen iphone and the wallcharger as been plugged into an extension nigh on 6 months without being removed not had a problem yet

Possibly because in the wall socket it just keeps sending in power and over charges it, but the USB into your computer stops sending it power once it reaches "100%"

Just speculating.

This guy noticed as well I guess ---> http://forums.whirlpool.net.au/forum-replies-archive.cfm/1116969.html

Well the iPhone battery can't overcharge so that can't be it.
As for the chargers getting recalled that was only for the US, because in EU we have better standards for these things. The metal things here don't break easily i tell you that!

whatever guy, it had nothing to do with metal prongs -- they overheating and causing melt downs. ;)

No... they changed the prongs on the replacement units. If you look at the original vs. the new ones, the new one's have tapered edges on the prongs. They weren't catching on fire.

Nowhere in that link does it mention they caught on fire or melted. The prongs did indeed break off causing some users to experience an electrical shock.... not fire.
 
Wall Charge vs USB Charge

From Apple:

http://support.apple.com/kb/HT1476

Connect the device to your computer (not your keyboard) using the included cable to charge the battery and sync. Your computer must be turned on and not in sleep or standby mode. If the device is connected to a computer that's not turned on or is in sleep or standby mode, the battery may drain.
