We're hoping to re-release a battery test for iOS in the future
but as of right now we don't have an exact timeline of when that
will be available. If you do want a refund, you will need to
request one from the Apple App Store, in your "purchase history"
page. If you have any other questions feel free to email us at

We're working on an update to the battery test. It's in the final stages of testing, and should be available late August. Thank you for your patience, and please let me know if you have any other questions.

The battery benchmark available in 4.2.0 allows you to measure the battery performance of a device by measuring its rate of battery discharge as it completes a consistent load of processor-intensive tasks.
You can run the battery benchmark by selecting either the partial discharge mode (which runs for approximately 3 hours or until the device discharges) or the full discharge mode (which runs from 100% battery level until the device discharges). The battery benchmark provides a score along with a confidence level, which is affected by how long the battery benchmark ran for, as well as some details such as a graph of your device's battery level over time and how the workload was modified over time (if at all) to provide consistent activity.
I've asked them to add explicit information about airplane modern the app, and in that conversation we agreed that it most probably is beneficial to use airplane mode since some background network activities could have a non-negligible effect.
