For those of you who wear your AW to sleep overnight .... how much does your battery drain overnight? I usually charge mine to full before bed and until the past few weeks, it has averaged about a 5-6% drop overnight (I usually sleep 6 hours). The last few weeks, though, it has dropped 10-12%. I haven’t installed anything new .... and my sleep patterns have been the same. Just wondering what everyone else experiences. I’m wearing the 38mm nike plus cellular.
