New Samsung S3 Miui V2.11.16 Battery Drain

Nov 21, 2012
Hi, I've just install the rom ytd and realize that my battery is going down way to fast and in the battery status i have 1hour plus usage for 88% of battery life. My display is using up 60% of my battery but my brightness is down to the lowest. I've got stock running power saving and touch key light are off. it's still going down rapidly. is there any way can i slow it down?
