Great app, but it eats up battery! – Shopping List (Grocery List) Review

I downloaded and used this app for the first time yesterday during my weekly grocery shop. For the most part it was wonderful. I did notice that after my time at the store, it had eaten a large chunk of my battery. Also, one thing that I wish was an option is a choice for each item whether or not it was a taxable item; as-is it is all or nothing which was a bit frustrating (not crucial yesterday, but at times when I have a very limited budget left it makes a HUGE deal).
