Google reveals that Nest doorbells can't charge in cold weather
In a recent update, Google has confirmed that some of its Nest devices can't operate or charge at low temperatures. This problem could mean that your device stops working during cold weather. The affected gadgets are the battery-operated Nest Cam and Nest Doorbell, which have a minimum operating temperature of -4°F (-20°C) and a minimum charging temperature of 32°F (0°C).
Google also warned that colder climes could reduce the speed at which your device charges. Plus, at -4°F (-20°C), the device's battery life may be less than half that it would see in warmer months.
To fix the issue, Google recommends that you charge the battery indoors; it may charge slowly at first as the device warms up to room temperature. There is a maximum operating temperature too, 104°F (40°C), at which the battery will continue to charge without issue.
In the article, which was posted following complaints from Nest customers, Google noted that wired Nest Cam devices would not be affected by this problem, as the camera can use the wires to draw power if the battery runs out of charge. However, this is not the case for the wired Nest Doorbell as its wires do not directly power the gadget; they trickle charge the battery instead.
It's worth noting that this low-temperature charging issue is common for the lithium-ion batteries which power the Nest Cam and Doorbell. For example, the same problem occurs for smartphones that use this battery type. As outlined in this article by the Amazon-owned company, battery powered Ring doorbells are also affected by cold weather.
