I bought the Pro 4K and sent it back because of horrible battery life, disconnected constantly from my internet and it had grainy pictures. I purchased another Pro 4K and it stays connected with great pictures but the app shows 100% battery life after running for 12 days! I know it's a bigger battery but I receive 10-20 events per day. It has to have used a percentage of battery life by now! Is anyone else having this problem?
