MDM 9.0.90 on iOS iphone 6 drys battery

Hi, since last week when the version 9.0,90 was released, my iphone 6 battery doesn´t last more than 3-4 hours. Before this update, the phone was working normally for 10 hours with no charge needed.

I have unistalled MDM profile and MDM App, and now the battery is working better than ever. 
please check this issue because final users will not be comfortable whit this performance. in their phones.
