How to Enable/Disable Battery care function on Sony Vaio to improve Battery life.

Sony Vaio Battery care function increases your battery life time and battery back up in the long run by limiting the max capacity of the battery to 80% or 50%. This means the battery would only be charged to 80% in each charge-discharge cycle. The backup would be lower in the beginning, but in the long run average battery backup would be more. Thus the battery capacity is not utilized fully.

Battery life will be about 80% of the one of the fully charged battery, however, this mode prevents battery degradation and is more effective if you usually use the computer with battery power.
[Note] When you use the AC adapter to power the computer and the battery power is higher than the desired value, it takes time to reach the specified amount of battery charge. It is recommended to discharge the battery to less than 80% by using the computer with battery power.

In order to enable Sony Vaio Battery care function,

  • Take Vaio Control Center (from Control panel or by typing Vaio Control Center in the start menu).
  • On left side click Power management and then click on the Battery sub item
  • Click on enable Battery care function as shown below.
    Enable battery care function on Sony Vaio
    Uncheck it to disable battery care function.
  • Click on advanced and choose 80%
    Battery care window

If your computer is charged to 100%, unplug from the power source, and let the battery go below 80%.

Now you should see lesser battery degradation. :)

    • sony vaio battery care

      You dont have to unplug or remove the battery. Just install the utility and your battery would be charged only to 80%.

  • reason why is better in the long run

    I already read that info in my brand new vaio, but can't find a review or opinion about the reason it will be better in the long run.
    The battery states to last up to 6 hours, but it barely get up to 5, plus 80% it goes down to 4.30 hous, and the last 10% is asking you to plug it again or it will go in hybernation...

    Total, a bit more then 3 hours of utility time. Good computer but battery life not enough imo

    I tried to search for the Vaio Control Center on the Start Menu, but nothing comes up. I don't think I have any Sony Software on my laptop anymore
