[Mac-BR] Fwd: bateria macbook pro

[Davi C. Rodrigues]

Fargas, obrigado por nos contar sobre sua experiência com a bateria. Mas
segundo minha experiência acho que seguir à risca o procedimento sugerido é
trabalho desnecessário.

Minha situação é a seguinte: tenho um macbook faz um pouco mais de 2 anos
também, e o iStat informa que a saúde da bateria está em 100% e esta está no
ciclo 118. Por que tanto ciclos? Além de eventualmente o usar sem estar
plugado, eu dificilmente desligo o meu laptop e deixo ele em sleep mode
enquanto o estou transportando.

Eventualmente eu uso meu mac até ele chegar abaixo de 15% de energia de
bateria. Mas isso ocorre de forma natural em torno de 1 vez a cada 2 meses.
Não me lembro se alguma vez chegou a ficar com menos de 5% de bateria.
Também nunca esperei as tais 5 horas com bateria zerada ou quase zerada para
depois começar a recarregar.

Considero que a saúde de minha bateria está muito boa, senão perfeita. Se a
vida útil da bateria é estimada em 300 ciclos, isto me leva a crer que a
minha tem ainda ao menos mais uns 2 anos e meio. Uns 5 anos de vida útil de
bateria me parece um tempo já extraordinário.

Abraços,
Davi
