I have owned a Samsung Gear 2 smartwatch for some time and have enjoyed the features and benefits of wearable devices for tacking exercise, messages, and phone calls. During this time my Gear 2 has had about a 5 or 6 day battery life between charges. However, recently my Gear 2 will not last over 12 hours. The only changes I am aware of is that my Galaxy Note 4 phone had an Android update and the Gear Manager App plugins soon followed. Ever since all the operating updates my Gear 2 has sorry battery life. I have read previous battery issues and recent issues with the newest Gear S2 and tried to turn of notifications etc. While some improvement my Gear 2 will not last a full day.
