Used my Apple Watch 42 mm for the first full day today and I am less then impressed by the battery life. Took it on this morning at 7am - at 8 pm tonight the watch went into power savings mode. Not great. Of course first day with the watch I used it maybe more then I would usual but not to much as least not as what I would think. I am wondering if I have a lemon because the reviewers in general did not have any issues in regards to this.
