I just upgraded from a mba to a new mbp with retina. I find that the magsafe 2 magnet is much stronger than the magnet that was on my macbook air. I thought I read previously that people were complaining about how easily the magsafe 2 comes off their mbp retinas. Mine is really solid. What are others experiencing?
I think the Magsafe 2 magnet had to be stronger since the connector is longer by a long shot than either the original T style or the more recent right angle style.
Frankly I'm not sure why it's as long as it is. The reason may be that the design takes the strain off of the cable where it had a habit of breaking at the top of the strain relief. In any case, the length is problematic. It allows the cable to apply enough force tilting the connector up that the magnetic connection is pealed apart.
I have a couch that's relatively soft so, when I'm sitting on it with the laptop on my lap, the cushion to the side of me is an inch or two higher than the top of the computer -- particularly if I have the MBPr supported by one knee and the couch. Invariably the connector gets tilted up by the cable and disconnected. Often the top of the magnet is still engaged in the connector, but the pins are no longer making contact. This didn't happen with either the previous right angle version or the original short T version.
I was a big fan of the right angle connector. For most directions you might accidentally yank the cable, it would disconnect easily, but it would never disconnect by local movement of the cable. Others have mention that they were concerned about the right angle connector because pulling it straight back it would not disconnect easily enough. One person has also mentioned that the right angle one would get caught in the hinge. I've never had that happen.
For me personally the Magsafe 2 long connector style is not an improvement. More than once I've run the battery down think it was connected when it was not.
