Beautiful but short battery life imo

If they upgrade these, I hope they have a much better battery included with it. These really are beautiful and bright and have plenty of color options available. One setting even goes through each of the colors. The battery life after being in the sun all day long from sun up to sun down is only 3 hours, maybe 4 tops. Some would be okay with it but I've purchased many solar lights that stay on until the sun comes back up the next morning. I absolutely love the idea of these, but for the price, they need to include a much better battery!
