Game lags on iPhone in low power mode.

My game runs smoothly at 30 fps when my iphone is in normal battery mode but starts to lag a lot when I put it in low power mode. Has anyone seen a huge difference in performance. Also I wanted to know if there is a way in unity to detect low power mode in iOS or I have to write my own plugin for that? Any help is appreciated. Thanks.

I have written my own plugin to detect the low power mode. If anyone is interested and needs to use it you can find it here.
