Galaxy S4 upgraded to Lollipop, run time from a full charge is reduced..

[AC Question]

I am hearing there is a known bug with 5.x.x that will be fixed in Marshmallow 6.0. Something related to the WWAN radio being left on too long.

Is this accurate? Does anyone have the details?

Welcome to Android Central! I don't have a direct answer for that, but have you already tried a cache partition wipe, which can be useful after a major system update? http://support.t-mobile.com/docs/DOC-5744
