Two days ago my battery life took a turn for the worse. Two things seem different. First, I downloaded the Amazon app. Second, when I look at the battery data it shows "MAPS" as having eaten up athe biggest chunk of battery life (Maps-39% and Display-25%). Yesterday, prior to looking at battery life, I did notice it was running in the back ground. But the battery life only tanked 3 days ago. Has something changed to make Maps run automatically? Is it the Amazon app? It does seem that my problem coincided with downloading this app.
