Strange WiFi battery usage on Marshmallow Nexus 5 I have a question about the WiFi battery usage on the Nexus 5. In the first screenshot you see my battery/WiFi usage. The second screenshot shows the battery/WiFi usage for the Nexus 5 of a colleague of mine. 



Strangely enough, my WiFi is disabled. Why is this so?
There is a known issue on Nexus 5/6 with Marshmallow and wifi. This wifi drain has been noted by many users, me included.
