It seems like my Focus uses more battery since upgrading to Mango (forced upgrade). However, I don't know if it's because of Mango or if I'm using the phone more.![]()
I will echo this suggestion. My battery life has been about the same, but my live tiles do seem to be updating better than in NoDo and, as such, I'd assume slightly lower battery life.Maybe check the Background Tasks in application settings and see if there is maybe a lot of apps running tasks or one in particular that is running larger than normal jobs.
