Absolutely that's a problem with Android. It's a natural consequence of having a platform where apps are free to access pretty much any hardware in the background with no review (that's a good thing if you're a developer though). However, Android gives you tools to see which apps are using the most battery, and you can uninstall them if they're a problem. Recently I noticed much worse battery life on my nexus 4, opened up the battery stats, and saw 30% of my battery usage was the consequence of a messaging app I don't use, deleted it, and got back to normal.
