Disminución de bateria en MacBook Pro 13. / Decreased battery in MacBook Pro 13.

Question

Tengo una MacBook Pro de 13 pulgadas posterior a 2011; hasta ahora la batería había durado bien (aproximadamenta las 7 horas) pero recientemente, y de un día para otro, disminuyó considerablemente su capacidad y empezó a durar un máximo de 2 horas. Es importante aclarar que no he aumentado el número de programas abiertos al mismo tiempo, al contrario los he disminuido, pero no sé porque pueda ser, si es a causa de software o de hardware.
I have a 13-inch MacBook Pro back to 2011, so far the battery lasted well (aproximadamenta 7 hours) but recently, and overnight, significantly decreased their capacity and began to take up to two hours. It is important to clarify that I have not increased the number of programs open at the same time, unlike the I declined, but I know that I may be, if it is because of software or hardware.

Answer 1

The battery life is stated as "up to" 9 hours, not promising 9 hours. Having said that, I would suggest using a browser other than Chrome, as it is often considered a battery hog. Also note, it is perfectly fine to use the computer with the AC power connected. As a rule of thumb, use it AC power when available, and on battery power when portability is required.
