Google’s Nest Doorbell may not stay charged even when wired this winter: gadgets

This is why ring cameras have a small heater on the battery. When the temp drops, it keeps the battery warm and charging right. So Google must have skimped out $ 0.15 per doorbell, and created this problem instead Edit: Amazon also did something similar on more recent rings, post their acquisition. They didn’t fix the problems Ring had, they just removed those features.
