I have charged my Ring Video Doorbell 2 on multiple occasions overnight with different USB cords matching the ring doorbell and the doorbell will not hold a charge. It is not hard wired, straight batter operated. Do I need another battery? If so; what kind and where do I get one? I read a lot of people have been complaining about ring updating their firmware? Any suggestions are appreciated to help me solve this issue! Thanks!
I’m now having the same issue. Used to last 3 months, now less than a week. The doorbell is less than 12 months old.
Hi neighbors! Battery usage is often related to the daily number of events, among other factors. Many motion, ring, or live view events can drain the battery quicker. Check out our Community Post about battery draining to see how to best optimize battery usage.
You can also find additional batteries on our website, here. 
I’ve only used to charge my doorbell 2 every few months and suddenly I’m having to charge it every 2 or 3 days.
Could this be due to an update? I’m getting fed up now.
