Displaying either the battery voltage or the battery level is misleading.
Regarding the battery level: if the result of the calculation is 50% the only use for that value is if the user knows when the battery was first installed since the desire is to attempt to anticipate when the battery will need replacement. For example if the level is 50% and the installation date was known to be 100 days ago the implication is that the battery will last another 100 days. This is totally wrong since the depletion of the battery is not linear as discussed at https://github.com/ruuvi/ruuvitag_fw/wiki/FAQ:-battery .
Even reporting the current battery voltage leads the user to do come to the same incorrect conclusion.
A much better, and in fact the only predictor of the nearing of end-of-life for the battery is unexpected resets which should be displayed as presented in issue #17
