Should an iPhone recharge when plugged in to a MacBook Air which itself is plugged into its wall charger?
My MacBook Air was closed and plugged into its wall charger. The green light on the power cord was lit. I plugged my iPhone 4S into the MacBook Air USB port under the MagSafe connection. I went to sleep. When I awoke seven hours later, the iPhone was at 30% charge. I thought it would be at 100%.
Is something wrong?
