Frequently asked questions

How do I keep my maximum battery health over time?

Among all the tips these should be the most practical:

  • Try to avoid high temperatures. (Apple...)
  • When you know you'll not use your MacBook for a few days try to discharge the battery to about 50%-80% 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.

My current maximum capacity is higher than the design capacity. What's wrong?

"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.

Battery percentage on my iOS device differs from the percentage coconutBattery is showing. What's wrong?

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).

I have a 16GB iOS device. Why coconutBattery says "X GB of 12,5 GB" is used? What happened with the missing 3,5 GB?

iOS takes a quite large amount of your memory. coconutBattery only counts the space that's available for your data (photos, music, apps...)
