I've yet to see such. Or rather, there was a company with longer life span batteries with 1000 cycles instead of the usual 300 but if you fit the biggest battery they offer it isn't any longer life (still 300 cycles) but since each cycle has more hours, the months you get out of a battery are higher.
Did you calibrate the battery?
I love my my Ideapad laptop, but the battery life is so poor, I rarely disconnect. Does anyone know where I can find a long life replacement battery? I have searched but have had no luck. Thanks!
