Battery percentage suddenly drops from ~60% to 7%
A few weeks ago, I decided to replace my macbook’s battery - after 5ish years, the only thing about this laptop (the best laptop ever made) was the battery life drained quickly. I ordered a battery + kit from iFixit, and replaced the battery. I conditioned the battery, but every time it discharged it would jump from above 50% battery to 7% battery, then die shortly after (i.e. a very discontinuous discharge). I received a replacement battery for the replace from iFixit, and replaced again. However, I’m still having the same problem with the battery jumps . I figure it’s unlikely to be the battery, but am unsure what else could could be causing the issue. I’ve reset PRAM and SMC.
Es esta una buena pregunta?
