current consumption is very high! Why?

On device I get feedback the app has a very high current consumption. In ten minutes the battery power dropped from 90% to 68%.

The app is showing ads during game play.

Is this maybe the reason for this or what can cause this and how can I prevent such high numbers?

It could be a memory leakhttps://forums.coronalabs.com/topic/22091-guide-findingsolving-memory-leaks/Sometimes the problem is in the device. Check if it is happening on more devices

Ads shouldn’t affect battery - unless you are showing them a LOT.  If you are running 60 fps that is an unnecessary power drain so drop to 30 fps.  If you are using device hardware like GPS ensure you only access it when needed and not all the time.  If you are doing a lot of networking, limit this as that is also a big battery drain - especially on 3 or 4G.
