I've had the collar for just about 10 days now and I've only charged it once. I love the collar and remote design. Even with some use the battery indicator for the remote still reads as full and the collar is down a bar. So far on battery life alone im willing to give it 5 stars. The adjustable vibration and beeps are typically enough to get my dog's attention, I seldomly have to use the shock function. Love the collar
