I'm seeing if this is just the issue with the 3rd party MagSafe charger, but I bought a spingen case (thin style); this doesn't have a magnate in the case. I find the magnate is weak in the 3rd party charge when I use the phone with the case. The 3rd party MagSafe can hold the phone really strongly when it doesn't have a case. Are you finding your non-magsafe case is not holding the phone to the apple MagSafe charger?
