AC Question
This facility was available via a simple toggle up to Kitkat but was removed in Lollipop. Various battery saving apps also used to allow mobile data to be turned off when the phone was sleeping. Again, this was stopped in Lollipop. I reverted to Kitkat because I can get over 3 days battery on my Nexux 4. Lollipop never got more than 36 hours.
