Battery Saving Apps
There are a lot of battery-saving apps on the market that claim to extend battery life, but my
experience has been pretty dismal, both on my Nexus 7 and my Android phones. The apps
I've tried either do nothing, or in some cases actually drain the battery faster than before.
An app that finally shows some promise is DU Battery Saver ( http://bit.ly/1EfOjLo ) . It has
an Optimize button that automatically shuts down idle apps, and a battery monitor that lets
you shut down apps manually. There is also an Optimize widget that you can use to shut
down apps without opening DU Battery Saver itself. I suggest you test the free version ex-
tensively before buying the paid Pro version.
