I have a Runner 3 since november of 2016. In a normal use, I needed to recharge the battery every four days, more or less.
Since I downloaded the last software version (1.7.64) the battery doesn´t lasts more than 35 hours.
Is there any problem with the last version of the software or is a problem of my device?
