The Android platform uses more battery usage. I like the live wallpapers as well. I am using the 1800 mAh battery and I am getting a lot better battery usage. I am not using a live wallpaper at the moment though. I like the stock ones and I have found free ones in the market as well. They are going to use more battery use. So, if that is the main concern, get a better battery. I like the 1800 mAh because it doesn't require a differnt battery cover, still a thin battery. I was recommend HTC Express website. It is a decent battery can get two with a wall charger for 39.99 and free shipping. I was charging up my phone 3 times a day. I can get 1.5 days depending on usage with this battery. Enjoy the wallpapers. I love everything the DINC can do.......
