Frequently Asked Questions

Among all the tips these should be the most practical:

  • Try to avoid high temperatures
  • When you know you'll not use your MacBook for a longer time, discharge the battery to about 50%-80%, power down the MacBook and keep the charger unplugged
  • For iOS devices: The faster your battery is charged the more this affects battery health in a negative way. Charging via USB will often be better for the battery as using a wall charger.

"Design capacity" is the capacity your battery should have, when it left the factory. As battery manufacturing is still a more or less chemical process, it may be higher (congratulations) or lower when it is put into your MacBook.

Before coconutBattery can access the device you have to "trust" your Mac on the device.
If you haven't received this popup from iOS yet, please try to connect the device via USB, open iTunes (or Finder in Catalina) and navigate to your iOS device. This should force up all the trust dialogs from iOS and macOS

iOS uses a defensive calculated battery capacity value to define 100% (and the percentage calculation). coconutBattery reads out the raw battery data and can give you more precise information.
(for example you will see that the device actually is still charging when iOS tells you that it is fully charged).

Cells inside current SSD devices can only be written a finite amount of time.
To make sure the drive will hold as long as possible the all SSD devices contain an intelligent firmware which is distributing writes evenly across the drive.
These algorithms are monitoring any write activity and are calculating a so called "Wear Level" or "Lifetime used" value which is an indicator of the remaining endurance of the drive (i.e. if 10% of the SSD lifetime has been used this means that the drive as reached 10% of its estimated lifespan)

A "Lifetime used" of 100% does not indicate imminent drive failure but is a good indicator of overall health of the drive.

Please open iTunes (or Finder in macOS Catalina and above) and switch to your iOS device. Please enable the "Sync with this iPhone/iPad over Wi-Fi" option (or the "Show this iPhone/iPad when on Wi-Fi" in macOS Catalina and above))

The manufacture date is not available on new Apple devices as Apple changed the way they encode the manufacture date in their serial numbers
