I got my new Forerunner 955 and have been using it for almost two weeks now. I noticed twice now that the battery drains faster than expected. Just recently, last night, I charged it to 100% and wore it overnight. I had the backlight turned off and other typical standard "sleep" settings enabled. I woke up this morning to find the battery at 89% - this is too much battery drain. I've been reading the old threads about 955 battery. My software version on the 955 is 22.18
Help - anyone?
