I am on 4.4.2 and am toying with idea of upgrading to Marshmallow, mainly to use *doze* feature

I have 150+ apps and want to check how many of them are upgraded to work with Marshmallow, *before* upgrading (upgrading my device Huawei Honor 6 and rolling back is complicated and not fail proof)

I am looking for a way to list all apps (on my device) are upgraded to API 23 and not upgraded to take a call. Manual verification is an obvious way, which I don't want

Is there a way to achieve this? ( including app based )
