Shutdown suddenly with >50% battery
I'm having issues sometimes with a new battery. In Genius Bar check correct battery health.
The problem is that the battery state changes from goog to poor state and the system suddenly stops using it . Have or not the charger, stop using it. So if you do not realize and disconnect the charger turns off and if you have the charger turns off directly .
When this issue occur it's necessary make a smc restart and wait to fully battery charge. Otherwise battery seems dead.
In powermanagement log,
Feb 24 02:33:59 MacBook-Air-de-migue powerd <Notice>: Battery health: Poor; was: Good; reason Permanent Battery Failure
Feb 24 02:44:05 localhost powerd <Notice>: Battery health: Poor

Versión de la ROM de arranque: MBA51.00EF.B04
Versión SMC (sistema): 2.4f19
I appreciate any help .
I made the snaps with the 'poor' indicator, this time when I remove the charger not turned off. I have made a smc reset and take new snaps with battery state 'good'.

Is this a good question?
