    I have used my MBPr (MacBookPro11,1) since 15 months without a glitch, was getting decent battery life,
    updated my OSX to 10.11.2 BETA 4 along with the newer recovery update TWO DAYS ago and since then my mac started to shut down abruptly and randomly at 30% charge, 20% charge. Pressing power key does not help, plugging in boots the system up.

    Now my system report shows:

    Designed Capacity : 6630
    Current Capacity: 2373

    Charge Remaining (mAh): 1194
    Fully Charged: No
    Charging: No
    Full Charge Capacity (mAh): 2373
    Health Information:
    Cycle Count: 424
    Condition: Normal
    Battery Installed: Yes
    Amperage (mA): -549
    Voltage (mV): 1174

    As you can see i have only got 424 cycles on my battery, i do not understand the sudden problem it has got.


    Battery life previously: 7hrs on average
    Battery life now : 3 hrs

    I have tried jumping back to OSX 10.11.1, but no gain, i will be trying to wipe the drive and reinstall OSX 10.11.1 along with the recovery.

    Any help and suggestions in this direction will be highly appreciated.

    Start from scratch and do a clean install of the latest OS X version is what I recommend.
