I'm translating an article about wearable smart watches. What does "replacement" mean? And what does it refer to in the following context?
[snip: (The author is unsatisfied, because of the high battery consumption of smart watches.)]
That is the single most pressing reason why I am not going to bother bringing any of my Android Wear stuff to CES next month because it is just one more cable, one more charger, and one more item that I will either forget to use, or just as bad, I will end up leaving it at the hotel where I then have to chase it down to have it sent home, or spend some money to replace the part. Of course, the smartwatch won't have enough battery life to stay "on" while the replacement is en route either.
