- 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.

When I connect my iOS device I only get the message "Access to iOS device denied"

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 and open iTunes. This should force up all the trust dialogs from iOS and macOS

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...)

Where can I find the Advanced Viewer for iOS or Mac in coconutBattery Plus?

For the iOS Viewer please open the "iOS Device" Tab in coconutBattery Plus, click on "Device details" and then click on the Info icon in the top right corner

For the Mac Viewer please open the "Mac details" popup in the main view and then click on the Info icon in the top right corner

What is the "Lifetime used" of my SSD shown in the Advanced Viewer for my Mac?

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.

My iOS device isn't available in coconutBattery Plus via Wi-Fi. How do I enable Wi-Fi sync in iTunes?

Please open iTunes and switch to your iOS device. Please enable the "Sync with this iPhone/iPad over Wi-Fi" option
