    mono - From first hand experience: I had my 15" MBP for about 2 years, kept it plugged in the whole time. Then over the course of a few months I noticed the battery health was dropping dramatically — it had been hovering around 60% for a year, now it was hitting 20% — and when I did run off the battery it was lasting less than an hour. Then one weekend the battery just stopped holding any charge at all, it was completely fucked (solid red when the calibration was checked) and I had to get it replaced because the machine wouldn't even turn on.

    So I drain the battery every month or so.

    • and you think this had something to do with having it plugged in the whole time?monospaced
    • I've had my MPB for years, mostly plugged in, and it works for several hours on battery still and I've never drained itmonospaced
    • draining the batteries is a good idea. leaving them in, like all rechargeables, greatly reduces their lifespan.jaylarson
    • "leaving them in" = leaving plugged in"jaylarson
