i have to admit i didnt expect much from this watch in the first place i didnt expect it to even go through one day at work which can get very bumpy and crack screens on fitness bands so far this one has stood the test of work battery life on average lasts me about 2 days thats with no notifications and hr tracker off thats kinda sad but reasonable one thing i liked is the built in usb charger so i have to rate it 3.5 out of 5
