Instinct 2s – Erratic battery life all of a sudden after 2 1/2 years of use
The watch might stay at ~70 % one whole day but goes from 50 % to zero the next day. Some day a training session uses the battery normally, other session takes 30 % of the charge.
Is this the funeral for my watch?
The distributor (Finland) did not even bother to answer my email. I have not changed any settings.
Before this occurred, the battery lasted at least for a week with one charge.
