I am running 4.4.2 on my S3 (AOKP Task650) but unfortunately I am receiving some battery drain. Is there a Kernel I could use to prevent this and save more battery? Which Kernel do you recommend most? Also I am having issues with my Data. I get "E" for edge in a 4G LTE area? Is there a radio that I can flash or APN for this to fix that problem?
