Battery has lasted a LONG time!
I have only had to charge this one time so far and I've had it over 6 weeks. When in use its not on longer than a minute so it holds its charge well. I like this brush! It blends my liquid foundation very well and when I started using it I also noticed I was getting a lot more compliments on my makeup than before. So that tells me it must be doing something for me, LOL! I purchased it based on the price, as I was not wanting to spend a ton on something I wasn't sure I would use, and I am VERY happy with this purchase.  Because of the long battery life, I think I use it more than I thought I would.I find that having to always charge things makes it start feeling like its  high maintenance and I'm a low maintenance gal!
