coconutBattery 3.2.1

With coconutBattery you are always aware of your current battery health. It shows you live information about the battery in your Mac and iOS device (iPhone, iPad, iPod touch) including:

  • Age of your Mac, iOS device and battery
  • How often the battery was charged
  • Your battery health (capacity in relation to the original capacity your battery had when it left the factory)
  • and much more...

You are also able to save the current health information, so you can see the changes of your battery over time. With the online service "coconutBattery Online" you even can compare these information with others.

coconutBattery is and will always be freeware. If you like it, a donation is always very welcome.

Current charge
The current battery charge (in mAh - miliampere-hour)

Maximum charge
The maximum capacity your battery can be charged with (in mAh - miliampere-hour)

Design capacity
The capacity your battery could be charged with when it left the factory (in mAh - miliampere-hour)

Model
The Apple model identification string for your Mac or battery

Manufacture date
Calculates the age of your Mac or Battery using the coded production date in the serial number of your Mac or Battery (Note: for Macs only the manufacture week can be calculated, in this case the date represents the first day of the production week)

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...)

Why does coconutBattery gives a range at "Maximum charge"?

The maximum reachable charge (in mAh) should be between these two values. The lower value is the defensive calculated maximum capacity for your battery. In most cases your maximum reachable capacity is higher. You can calibrate this range by charging your phone to 100%. The larger value is the current theoretical maximum capacity of your battery. It only can be reached under optimal conditions (temperature, charge/discharge rate ...). In most cases you'll never reach this value. If you can charge your phone beyond this value, write me a message.
