I recently replaced the battery in my mid-2012 11in MacBook Air. It does not appear to be holding a charge. For instance, the charging cable’s green LED will indicate a full charge, but when I remove the cable, the battery percentage immediately drops to 95%-96%. The battery is also draining at about 1% every 2-3 minutes. I calibrated the battery correctly - or so I think - after I replaced it. I’ve also let it drain completely multiple times before recharging. Any suggestions?
There is no need to calibrate the battery on this model. When charge shows 96% or so, drain the battery below 90% and start charging again. 1% every 2-3 minutes sounds totally normal.
