Poor battery life

I love the styling of this smart watch; I wanted my smart watch to look like a fashion watch but I also wanted smart features like step counting etc. Overall the health monitoring works but the integration with google fit has been useless. All my walks are recorded as just 1 minute long or 10 cals. However the biggest issue I have is the battery life is terrible. If I put it on at 7:30 it puts itself into battery saver mode before 1:30pm , that's less than 4 hours of useful battery life!
