-#License
+Better Battery Stats provides more in-depth battery statistics for your Android device. It can be used to find applications that cause battery drain.
+
+It can be used without root, though it needs special permissions. With root access those permissions can be granted automatically. Without root access, the permissions can still be granted using the `adb` tool on a laptop or desktop computer:
+
+```
+adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
+adb -d shell pm grant com.asksven.betterbatterystats android.permission.DUMP
+adb -d shell pm grant com.asksven.betterbatterystats android.permission.PACKAGE_USAGE_STATS
+adb -d shell settings put global hidden_api_policy 1
+```
